Introduction

Leguminous crops are the most important source of plant protein, which is a fundamental part of people's diet and animal feeding. Such leguminous crops as peas and lupine white play the most important role for agricultural industry in the condition of the right-bank Forest-steppe zone (Lapinskas, 1998). Important scientific researchers results in the technology of peas and lupine growing were made by national and foreign scientists A. O. Babych, V. F. Petrychenko, A. V. Cherenkov, S. M. Kalenska, V. G. Myhailov, M. I. Bahmat, M. J. Shevnikov, O. M. Bahmat, V. V. Lyhochvor, O. V. Ovcharuk, K. Novak, B. Furseth etc (Hunt & Layzell, 1993).

Systematic researches that would promote optimizing the production process of high yielding and industrial peas varieties are currently important for increasing yields and improving grain quality (Davis & Narenda,1986). The important factors of cultivar adoption to growing technology of such peas varieties are improving ways of basic tillage, choice of optimum fertilization alternative, in particular biopreparations and modern types of fertilizers for foliar nutrition of sowing usage (Eviner & Chapin, 1997).

Leguminous crops that are studied are strategically needed high protein crops of modern crop production, and economic and bioenergetic valuation of their breeding efficiency is long-range and important issue nowadays (Bohlool, Ladha, Garrity & George, 1992). In present-day socioeconomic conditions one of the main problems of agriculture economic sector of Ukraine remains essential increasing and stabilization leguminous crops production, that are the main source of balanced in amino acid composition and content of eco-friendly protein (Bollman & Vessey, 2006).

Materials and methods

Field researches have been conducted on the basis of the Vinnytsia National Agrarian University's field in Agronomichne village Vinnytski rayon Vinnytska oblast during 2011 -2017. Soil cover is represented by gray forest soils that are characterized

27_Energy-economic efficiency of growth of grain-crop cultures_

by low humus content - 1.97%. The amount of absorbed bases is 1.44 mg Equiv per 100 g soil. Hydrolytic gray forest soils acidity of the trial field is 3.44 mg Equiv per 100 g soil, and pH salt is 5.1. Soil moistening is provided with atmosphere precipitation, since groundwater level is situated at a depth of 10-15 m.

Hydrothermal conditions during vegetative period of lupine white in 2013-2015 were different and characterized by certain features. However right-bank Forest-steppe zone in general is quite favorable for peas, lupine white and bean growth. In the experiment pea variety Ulus and lupine white variety Veresnevyy are studied.

The researches cover studying of effect and interaction of three factors. They are A - variety, B - foliar nutrition, C - pre-treatment of seeds.

Phenological observations were conducted according to "Method of state sort testing" (2000). Mathematical treatment of the obtained results was conducted by means of dispersion and correlation-regression analyzes (Dospehov, 1985; Vergunova, 2000) using modern program pack Exсel, Sigma and Statistica. Evaluation of cost efficiency of lupine white narrow-leaved breeding was conducted by means of Macybor O. K.'s methods "Agricultural economics" (1994). Calculation of lupine narrow-leaved growing technology energy efficiency was conducted using the Medevskogo O. K. and Ivanenko P. I.'s method "Energy analysis of intensive technologies in agriculture production" (1988) and the method of All-Russian Williams Fodder Research Institute (1989).

Results and discussion

The yield of grain legumes

The deficiency of vegetable protein, the orientation of agriculture to environmentally appropriate cultivation, as well as the high cost of mineral and organic fertilizers cause increased interest in legumes (Brelles-Marino & Boiardi, 1996). These culture-an inexhaustible source of soil enrichment by nitrogen compounds nitrogen fixing nodule bacteria in symbiosis with plants, and therefore have important agronomic importance (Brevedan & Egli, 2003). Their cultivation can reduce the cost of crop production due to the inclusion in the process of agricultural production of atmospheric nitrogen, improve the phytosanitary state of crops and significantly increase the productivity of arable land (Novak, Slajs, Biedermannova & Vondrys 2005).

The results of researches for 2011 -2013 indicate the significant influence of investigated technological techniques on the size of the grain yield of pea peas of the Ulus variety (Table 1).

The maximum value of the grain yield of white lupine varieties was obtained on variants of the experiment with pre-sowing seed treatment with an inoculum Risogumin and growth stimulator Emistim C in combination with two non-root nutrients Emistim C. In this case, the grain yield was 3.61 t/ha, and exceeded the control variant on 0.65 t/ha, and in percents, respectively, 18%.

The economic efficiency of the technology of growing leguminous crops

Grain economy develops due to increased economic efficiency of production, with an increase in gross and marketable products (Djekoun & Planchon). In the calculations of the economic efficiency of growing peas for grain, the indicators of grain yield, grain yield, material costs for its cultivation, labor remuneration, depreciation, repair, and others were taken into account (Dorcinvil, Sotomayor-Ramirez, & Beaver, 2010). The complexity of the calculations of economic efficiency consists in instability and disparity of prices for industrial (agricultural machinery, mineral fertilizers, pesticides, fuel and lubricants) and agricultural products (Duke & Collins, 1985).

The basis of the analysis of the economic efficiency of the estimation of the technology of cultivation of seedlings of pea has been laid the variants of pre-seed treatment of the seeds with the composition Polymiksobacterin+Risogumin and foliar fertilization with KODA fertilizers in the phases of budding, green beans and seed filling (Table 3).

The best indicators of economic efficiency, namely the profitability rate-119%, were noted for the technology of growing lupine of the white variety of In Veresnevyy, the lowest yield of gross (49526 MJ/ha) and exchange energy(27918 MJ/ha) in the Veresnevyy variety on the control version, where the bactericidal preparation Risogumin and the growth stimulator Emistim C in combination with two non-root nutrients Emistim C. were used in pre-planting seed treatment. Cost and profit were thus respectively-3657 UAH/t and 15680 UAH/ha.

Bioenergetic efficiency of technologies for growing leguminous crops

Widespread use of intensive technologies has led to an increase in the volume of fuel, electricity, chemicals and protection and, as a result, energy costs (Elkins, Hamilton, Chan, Briskovich & Vandeventer, 1976). The newly created technologies should be more plastic, which will allow them to adapt to the conditions of various resource-technological support (Mateos et al., 2001). They should provide for the maximum realization of the potential of cultural productivity (Furseth, Conley & Ane, 2011). The scientific substantiation of the technological process of cultivating crops will help to optimize the flow of energy through agrotechnical measures with the purpose of purposeful formation of highly productive agrocenoses (Furseth, Conley & Ane, 2012).

According to energy estimation, the technology of cultivating seedlings was the most effective, which included pre-planting of seed with the composition of Polymycobacterium+Risoguminum and the use of frozen fertilizers of KODA in the phases of budding, green beans and seeding on the background of fertilizer N45P60K60, which ensured a gross energy output of 76.24 GJ/ha, net energy gain-58.12 GJ/ha in the Ulus variety (Table 5).

In the article the processes of yield growth, development and formation of leguminous crops and influence of organized factors in view of hydrothermal conditions of right-bank Forest-steppe zone of Ukraine made on them are theoretically founded and practically proved. Researches were aimed at solution of set scientific problem. It helped to make next conclusions:

Top yield 4.31 t/ha of field pea variety Ulus developed owing to seed inoculation with Ryzohumin and Polymycobacterium and to arranging foliar nutrition with fertilizers CODA Fol 7-21 -7 in the stages of budding and green beans and CODA Complex in the stage of seed filling, that is relatively more on 1.16 t/ha comparing to control.

Seeds pre-treatment with the bacterial fertilizer Ryzohumin and the growth stimulator Emistim C in combination with two foliar nourishments with Emistim C conduced to development of the highest of lupine white seeds productivity. Therewith the productivity of the variety Veresnevyy was 3.61 t/ha that is more on 0.65 than without seeds pre-treatment. Evaluation of cost efficiency shows that the highest operating profit 8.1 thousand grn/ha, the level of profitability 108.9 % and the lowest prime cost 1.7 thousand grn/t were obtained owing to seed inoculation with Ryzohumin and Polymycobacterium and to arranging foliar nutrition with fertilizers CODA Fol 7-21-7 in the stages of budding and green beans and CODA Complex in the stage of seed filling. The same production methods provided the best energy measures and turned out to be competitive. So energy coefficient was 3.21.

Economic and energy analyses of growing technology shows that the lowest prime cost 3657 grn/t and the highest level of profitability of the variety Veresnevyy 119% were obtained owing to seeds pre-treatment with the bacterial fertilizer Ryzohumin and the growth stimulator Emistim C in combination with two foliar nourishments with Emistim C. In this case energy coefficient was 2.09.
