Abstract
Modern world tendencies of formation of the food and feed resources can't be solved without a solution of the protein crisis – a key component of the global food problem. The need for vegetable protein causes rapid expansion of the area under annual grain legumes, increase of their yield with the aim of obtaining a qualitative high protein food, valuable protein ingredients and, consequently, animal feed. Taking into account the biological characteristics of the narrow-leaved lupin, this culture can grow and develop even at the early sowing, that’s why the narrow-leaved lupin, like other types of this culture, belongs to the spring group of the very first sowing. The shown data evidences about the considerable prospects of this crop in agriculture, because of the high level of productivity and relatively short growing season, varieties of the narrow-leaved lupin can be popular among legumes, along with soya and peas. The purpose of the research was to determine the influence of sowing date and methods of the narrow-leaved lupin on the yield and seed productivity in conditions of Polissia, taking into account global climate changes. Weather conditions in the research years significantly differed in precipitation during the vegetation period of the narrow-leaved lupin (April-July). 2015 was the driest year with 105 mm of rain during the vegetation period, which is 2.5 times less compared to average multi-year norm. 2014 and 2016 were more moistened with 201 and 175 mm of rain respectively during vegetation. The lack of moisture in the soil negatively influenced the growth and development of the narrow-leaved lupin; this fact affected the formation of its seed productivity and quality of obtained seeds. In such weather conditions the potential of the variety and seeds is not fully used. Ineffective action of mineral fertilizers, which have been applied by basal and foliar methods, is observed. In this regard, in 2014–2016 there was the study of seed productivity of the narrow-leaved lupin and quality of obtained seeds from the harvest, which depended on the combined effect of technological factors in the context of global climate changes. Analysis of the results of the research that was conducted in the years with favourable weather conditions, helped to determine a clear correlation of the influence of sowing methods, seeding rate and fertilization system on grain yield of the narrow-leaved lupin, as well as the yield of certified seeds with their qualitative indicators. The highest average yield for research years was obtained using line sowing method with the seeding rate (0.6 million pieces/ha) of similar seeds with 15 cm row space with a complete fertilizer dose of N 30 P 60 K 60 in combination with two foliar feedings – 19,8 centner/ha of Grozynsky 9 and 16.0 centner/ha of Winner. The highest seed productivity, high quality of seed and the multiplication factor of the seed were provided by the sowing of the narrow-leaved lupin with 0.9 million pieces/ha of similar seeds by line sowing method with 15 cm row space and by interlined method with 30 cm row space with a complete mineral fertilizer N 30 P 60 K 60 in combination with foliar feeding of water soluble NPK-fertilizers with microelements. These sowing methods are suitable for growing of basic seeds of the narrow-leaved lupin in test and elite seed groups. The highest grain yield and the yield of certified seeds were got due to a seeding rate of 1.2 million pieces/ha of similar seeds by line sowing method with 15 cm row space with a complete mineral fertilizer N 30 P 60 K 60 in combination with foliar feeding of water soluble NPK-fertilizers with microelements. This sowing method and seeding rate are recommended for growing of certified seeds and commercial grain.
