As such lupine is of the greatest importance for a good growth of it can accumulate, by the time it is plowed under in preparation for autumn grain sowing, about 160 ralograims of nitrogen per hectare, that is, not less than are contained in 30 - 35 tons of man,.ire. It was estimated that in the European; portion of the USSR alone, (in the fon--chernozen area) green manure can be utilized yearly on an area of 2,5 million hectares A wide field for utilization of green manures is also available an Siberia, where fallow precedes sprang wheat, a nd hence a green cover crop can be plowed under later than it. is done in prepara. tion for au tame sowing. Within the sub-tropics, growing of legumes as green manure is also achieving great importance. Soring of legumes as green manure results in more rapid. effect than the sowing of clover and alfalfa (see above). These rn2 sure s must now be given especially great consideration in the ref abilitataon of a. ricua_ture in regions devastated by the war so as to raise soil fertility in spite of manure shortage, The use of green manures was previously restricted mainly to sandy soils, but now it should find the widest application, since it substitutes for manure ? shortage in any soil even in the cherno z,em belt, if used from autumn on in preparation for spring grain) But in this we encounter the obstacle of seed shortage In coinbatng this evil, selection of the plant acquires s Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 great significance, arid preference must be given to legumes producing sr sesince they require less seed per hec- tare and provide better opportunity for sowing the nitrogen- gathering plants in adndxture with other crops, thereby ob- viating the necessity of allocating a separate field to there in the spring (they are sowed together with a grain crop)6 Unfortunately, >>p to now, we have grown mostly- narrow- leaf lupine, which produces large seeds, This makes it neces- sary to raise the a 'ount of aced used to 160- 200 kilograms per hectare, 1rGrhich is expended to obtain only one mows ng of green plants, so that the expenditure must be repeated each year, Joreover, north oi' L oscow, where the seeds of this lupine do not ripen, there arises the necessity of meeting further costs and providing organizati onal measures in connection with she transportation of seeds, Therefore it is also necessary, without giving up development of seed production of the annual lupine, to utilize the perennial lupine having small seeds in the pro ciuct'L"n of wiiicji the ratio between the amount of seed and that of green plant ? teriai obtainable therefrom is 35 to 45 times more advantageous tlian in the case of the annual lupine. In the case of the former, one hectare requires about six times less seed (30 kilo;rams per hectare), whale the period of hay f1o~Tin gs is about 6 to t3 times longer (sometimes even 10 times) 0 In addition perennial lupine can yield in one summer from two G (near eningrad) to three (near Chern?gov) hay harvests, so that the above-referred to ratio in the case of perennial lupine is found to be about 100 times more advantageous than that attained in the case of the annual lupine.

Hence no early seed crop was obtained during that year, In addition to further steps in this direction one must, of course, develop by all means the production of perennial lupine seed locally in the northern areas, As an example of successfu solution of this problem, there can be cited the case of the Semenovskiy Rayon of Gor 'kiy Oblast 1.) It mush be pointed out that introduction o?' lupine culti- vation on fallow fields throughout the entire Non-Chernozer a area may also solve another very important problem; it greatly facilitates the labor-consun irrg operation of manuring. The fact is that if lupine (in con junction with phosphates and potassium salts) here to fully replace manure, on more distant fields of the holdings, the manure would need to be used only on . nearby fields (primarily for vegetables, but also for cereal grains), and if the average distance over which manure must be carted be decreased only one half, it becomes readily apparent what fuel cost savings would be attained in the performance of this laborious orperatican, ..of course lup:Lrre fallow is suitable primarily for sufficiently humid areas, but the turning under of mowed lupine grown on an i outside area will not produce the same drying_out effect obtained from growing the lupine on the field where it is plowed under. (According to data of the Sudogodsk Experirrrenta S ]. ~tation, it is necessary to replow the land after turning under the lupine fallow crop to prevent weed growth in the autumn sawn crop.) In the future rich sources of perennjal lupine seed? may be found among timbering areas where pines are grown on sand Experience in the west has demonstrated quite clearl r that Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 dESTRICThU inter-row growing of lupine for 5 - 6 years without any addi- tional care is a good method of promoting tree growth (thus a 20 year-old pine tree attains the size of a 30 year-old one groom without the use of lupine), while the annual seed harvest derived from such inter--rows of lupine on young plantations is an addi- tional source of income for the forestry enterprise, as well as an important source of supply of lupine seed for agriculture. Besides the perennial lupine there are, of course, other nitrogen collecting plants having small seeds, but none of them can be utilized as widely in the northern half' of our plain 0 Serradilla, for example 'if~en planted in rows, requires as little as 30 kilograms of seed (if the seed is scattered 45 - 50 kilo- ;rams are needed) . It can be sown with grain crops and yields in the au.tunn a good mowing of green plant growth suitable for use as feed and as fertilizer. chile this can be successfully :practiced in the Gherrigov region and in Belorussia, even in the vicinity of lVioscovr the autumn season is too short to permit u.tili- zation of serradilla after the grain crop with which it had 'been sown has been harvested. However, serradilla should be given due cons:i.deration within a very vd.de area, and it affords substantial advantages in rapid growth. Thus, wi erz sovn with cereal crops, it can be mowed in the autumn (and the remainder plowed under as fertilizer), while clover and perennial lupine can be mowed only in the followa.ng year. According to computations of Ye,.. ; K. Alekseyev, within Poles?ye and southern Belorussia there are approximately ley nalJ.ion hectares where 'serradila:a could be utilized (incJ.udin; ~ESraecr~~ Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 ft,~ Y?N 'k lM1. U TEn sowing in conjunction with grains). Still larger areas within which growing of serradilla, in one manner or another, is possible are located between Belorussia and the southern portion of Gor!kiy Oblast ? . There is no point of estimating their size, however, at present, since there a. ~ is a huge discrepanc between the required amount of seed and the quantity available. It is. important to in- crease this quantity, but here we can see the difference between annual plants, the growing of which as green manure conflicts with growing for seed production, and the perennial l.upinek which is adapted to give a seed harvest and still yield a crop of green plant growth for use as fertilizer. Among the other small-seed annual legumes suitable for sowing with grain crops the following may be of interest: hop- like alfalfa frequently grown in Germany; crimson clover which is found growing in 'rance and Switzerland, and the annual variety of sweet clover developed in the United States. These plants have been tried in this country to a lesser extent than lupine and serradilla. We should obtain, however, more seed than has been possible hitherto, in order to test them on a large scale. The fact that we are stressing the great importance of perennial lupine and serradilla does not mean that annual lupine is not worthy of our attention. It still retains its signifi- cance and possesses' certain advantageous features which are lack- ing in perennial lupine, Thus annual lupine can be sown on har- vested rye fields in southern Belorussia and in he Sherrigov area, it is also of interest as a seedcrop legume, especially the "sweet~i lupine which yields valuable nutritive feed. At the same time root residues remaining after the lupine seed crop has been harvested 1fl Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 e rmist point out that it is entirely` inadequate for such a large country as ours, to have available but one\ western lo- cated source of lupine and serradilia seeds We must create new sources in the central portion and in the eastern part of the country. As such, we believe to be suitable primarily for such a, purpose the huge area of sandy soils extending southward from Murom along the right bank of the Oka and the Tsna to Mor.,shansk and Tambov. Here can be found conditions suitable for the pro- duction of seeds of not only the blue (narrow lean) lupine, but also of yellow lupine; from here seed could be supplied to the northern areas where the seeds do not mature and also the e treme southt where seed is needed for winter sowing of lupine to be used as fertilizer, but where it is not war thwh],le to tie up. valuable land for seed production. Then it is possible that large amounts of lupine seed would become readily available where their production on a large scale is found advantageous by farming communities. An example of such advantageous production may be found in Earring areas in sandy soil regions, provided it is based on the tb.ree pillars of lupine, potatoes and hogs 1 had occasion to observe abroad in 192n/ fare ng prac- tices in sandy soil areas, where hogs were fed on a large scale exclusively on potatoes and lupine; but in those days lupine seed had to be steamed and soaked to remove its bitter taste, while now with trswee't14 lupine, available and serving as a valuable source of proteins in feeding young pigs this tedious operation ~ ~beera elirr .nated.

Un- fortunately outside of Belorussia this has not taken place up to now. For example, the Sudogodsk Station could not promote or- dinary lupine grown for seed in local farming cou nunities of Ivanov Oblast '; only the sweet lupine attracted. the interest of collective farm members. lupine harvested for seed leaves in the soil no less nitrogen than lupine turned under in bloom (this was ascertained by prior experi- ments of Kudrin), and, if farming practices also utilize lupine straw, the total amount of nitrogen put to use excluding the seed, is greater than that obtained on plowing tinder the lupine while in blossom, Incidentally, tests at the Sudogorsk Experimental Field have shown that the'straw of sweet lupine, when cut--up and treated with boiling water, is readily eaten by livestock. Since in the vicinity of Tambov and Yoronezh, rye can follow early potatoes, it is conceivable that on humous, riverside sands the following intensive four-course system is possible: lupine to yield a seed crop, potatoes, rye and serradiLLa (to be mowed after the rye harvest), and spring grain. But individual cases may ~,/ vary What is important is that lupine seed must cease being con- Let us consider other entirely novel possibilities of green manure utilization in Central Asia, where conditions have undergone drastic changes during the war. On the one hand cotton growing has been deprived of nitrogen fertilizers\ which played the prin- cipal part in the cotton yield increases, so that yields dropped ESTfflff' Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 sharply reverting to 1930 levels; on the other hand, in 1943 there became apparent unprecedented possibilities for a wide utilization. of green manures due to substantial alterations the rotation system. Up to then, farming was surfeited with o.f cotton, ' growing of grains on irrigated areas was not permitted at all. Hence farrns were deprived of straw, and without straw no means were availab7.e for absorbing liquid excretions of cattle, which contain all the nitrogen of the digested portion of al- falfa hay. Therefore there was little manure and it was poor in nitrogen. Hence the huge demand for mineral nitrogen and its shortage in cotton growing during the war. In addition, under the then-prevailing rotation system in irrigated areas, no use could be made of autumn sown nitrogen collecting crops. The system of sowing cotton in succession to cotton for six consecutive years precluded utilization of this procedure, since cotton occupied the land until December, when it is too late to sow winter peas, while attempts to sow peas between rows before cotton harvest time were not successful. But since 1943, of the 900,000 hectares of irrigated land in Uzbekistan previously cropped exclusively to cotton, 300,000 hectares were allocated to grain crops and sugar beets, thus making possible the modest utilization of autumn--sown nitrogen collecting crops. Since not only grains but sugar beets as well are harvested much earlier than cotton. (Partial harvesting of the beet crop must begin on August 15, since at that time the sugar content of beets planted in March reaches 17 percent, and it is mulch more advantageous to put the mij.ls in operation earlier than to process later on in 9arch beets of 10 - 12 percent sugar? content because beets in Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 ~ESTA1~ the south stand storage less well than in the Ukraine. But the most extensive field for utilization of autumn-- sown nitrogen collecting crops develops on the area vacated by grain crops. In the case of winter grains it is possible to visual- ize the attainment of a three--stage sowing and to effect autumn planting of legumes as the third sowing of the season. Since har- vesting of winter barley begins around Samarkand about June 1st and in Tadzhikistan and Turkmeniya in the middle of May, it is possible t.o have another harvest of a food crop (potatoes, early varieties of dzhugora, etc , ) and still make passible a sowing of winter peas in September or October depending on the latitude. The winter-grain crop can also be sowed together with Persian c1o-- ver and use its summer mowing either as hay or green fodder, (whicii would yield additional amounts of milk, which is so badly needed in Central Asian towns) and carry the second stand through the winter to be plowed under in the spring as a green manure for cotton. Finally, there are data (Ge1ltser) showing that certain varieties of peas, if irrigated after grain harvest, continue to ..L grow and yield again a stand of green plants; thj.s it is possible to sow in early June peas as a seed crop, leaving the harvest residues to serve as a fertilizer for cotton through subsequent plowing under in October - November or in the spring, L Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 Concerning the effectiveness of green manures under Central Asian conditions, we can cite the results obtained by Academician Ye. K. Alekseyev near Samarka>7d in 1942. He at- tamed a doubled yield of beets (384 centners as compared with 182 centners of control) through having peas plowed under as a fertilizer. In Kazakhstan there were obLai.rmed increases in the flSTRCTEk)' Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 13- Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 flESTRtCI E yield of beets amounting to 140 160 centners due to after harvest green manures (Zubrilin), (lie do not make reference here to ;previous experiments in which the green manure crop was sown in the spring in lieu of cotton; at present only after-harvest growing and concurrent growing of nitrogen fixing crops are of interest,) Analogous effect must be produced on cotton by green manure. The question of the special importance of wide utilization of autumn-sown nitrogen fixing crops in Central Asia during the war was raised by me in the sprang of 1943 so as to allow time for obtaining seeds from the United States. We were unable to secure these seeds by the autumn of 1943, but in 19/4 a shipment of 4 thousand tons of winter peas and other nitrogen fixing plants was received, which were used for propagation. if by so doing, the supply of these seeds is raised to 30 ?- 45 thousand tons, this amount, would be sufficient to cover an area of 200 - 300 thousand hectares, which would constitute an important factor in raising cotton yields in Uzbekistan. While my suggestion, made in 1943, relative to the sowing of nitrogen gathering crops following the harvesting of grains and beets was limited, in spite of the importance of this m.eas- ureb to only one out of six fields of cotton, encountered in the usual rotation systems, as early as 1944 1 raised another question, namely; would it be possible not to limit this procedure to a single application, but to find means for utilizing it repeatedly'? In this connection there appeared the possibility of a' wining even a 100 percent saturation of the cotton-growing area with nitrogen fixing crops without decreasing the planting of cotton.

Experience gained in Egypt nnot, of course, be. applied directly to the . ca entire cotton belt, but on due consideration there might be certain problems which should be studied by derived therefrom our own researchers, The basic problem which interested me is the foLLowing; In some portions of Eg rpt, especially in the delta of the Nile, ~~ there is practiced the repeated sowing of cotton on the same areas, cannot be designated as a single crop method because and yet this in between the consecutive cotton crops the land is cropped to 4~andria clover which produces several. mowings during the ~~le,~ uvinter period; the last of which is not utilized as hay, but is plowed under as green manure . The acreage under this clover in Eg~. )t is about 520 thousand hectares, while cotton occupies 770 thousand hectares, i.e, practically all the cotton is planted in succession to clover. In pa b there is also cultivated on the same dual rotation system, another pair of crops, there, rarely corn and ,^rheat, but from our standpoint what is import-- rn ant is the fact that as a ?ule cotton is sown over plowed-,under clover, which is its main source of nitrogen. Could we not adopt some similar method in our country'? Would it not be possible to obtain at least one legume crop between two sowings of cotton? Flitherto it apl,)eared tl:Lat this could not be done, since experiments in which winter peas were grown with cotton did not yield satisfactory results ? however, we should not give up and consider the problem as being settled; we must test different nitrogen fixing plants, different methods, Es*ctuciE9i Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 Declassified and Approved For Release 2012/03/08 : CIA-RDP82-00039R000100200009-0 and times of sowing. That a transition is attainable by such means is apparent from the publications of V. C. Petrov (see Sov]oye wproizvodstvo, 1944, No 7) concerning the planting of winter Mith. cotton, which previously also did not produce good results, but now, according to data presented in the above- referred-to publication, the problem could be solved satisfactory ily, if the proper variety (one of the Cxraecum species) were to be u~~ red, and the he time of sowing changed. The wheat is sower bet'Neen cotton rows fairly early - in August, k, This leadsnto believe that~mong the numerous varieties constituting the genus of legumes, there con be found annual species adapted for sowing in conjunction with cotton. l~hereas Alexandrian clover may be suitable only in Tadzhikistan and hrkmeniya, in TJzbekistan we must consider, for instance, fenugreek (Trigonella foenum raecum ) which is grown successfully as a feed crop in Azerbajdzb,n, where it is called "sharnbola". The i growing of this crop is centered in the Nakhichevan' Kray, where it occupies a fairly prominent position among field crops.

Insofar as selection of green manure crops is con- cerned the conditions which hinder wider utilization of annual lupine in the northern portion of European USSR and induce its replacement by the perennial lupine are the very conditions v'rhich prevail on a wader scale in Siberia e They include, among others, the possibility of growing the seed locally and greater ease of seed transportation. Of course, in Altay and inusinsk krays the annual lupine can also be grown for seed production but there is also the fact that 30 kilograms of seed are suffi- cient in lieu of 180 - 200 ki.:Logratris to effect the sowing may be the determining factor. h many instances sweet clover will be found to be useful, since, while unsuited on acid ,soils, it is better adapted than lupine for solonetz 50?14 and weakly alkaline soils and may be thus used \ ?th spring-sown grains and. plovred under the next year as a fallow crop (the fear that sweet clover will become a weed is unfounded; all that is nec~ essary is to prevent seed formation).

It is very difficult to say what portion of them could be utilized in the future m It is clear, however, that with a general shortage of fertilizers, one may not ignore the vast possibilities afforded by this source of nitrogen, especially utilized in conjunction with peat.

In the same manner solar heat could be used in the production of poudrettes from ordinary mixtures of excreta when these are first subjected to a chlorination process. Thus several results would be at- tained simultaneously; - conservation of ammonia, sterilization, and elimination of objectionable odors.
