PRODUCTIVITY OF RAPSO-BARLEY MIXTURE IN THE INTRODUCTION OF MINERAL FERTILIZERS
The purpose of the study is to study the features of growth and development of rape-barley mixture, to determine the effect of mineral fertilizers on the productivity of intermediate crops in the conditions of Central Tajikistan. The experiments were conducted in 2017-2018 years. on irrigated serozem meadow lands of an experimental production facility located in the Gissar district. It has been established that intermediate crops (rapeseed, barley) are an important source of feed production when the need for them is particularly high. It is proved that the optimal rate of mineral fertilizers for rape-barley mixture is N90Р60К40 kg/ha, which ensures 505 centners/ha of green mass or 75.6 centners/ha of dry matter, corresponding to a yield of 96.0 centners/ha of feed units and 12,5 kg/ha of digestible protein
