THE PRODUCTIVITY OF STANDARD SEED AND SOWING QUALITIES OF WHITE SWEET CLOVER IS DEPENDING ON ELEMENTS OF AGROTECHNICS

Abstract

The results of experimental researches are resulted from influence of technological elements on forming of the seminal productivity of white sweet clover. A purpose was to set influence of width of spaces between rows and doses of nitric fertilizer on the productivity of standard seed and sowing qualities of different sorts of culture in the unirrigated terms south of Ukraine. Researches conducted during 2016–2018 on the base of Institute of the irrigated agriculture of NAAN in obedience to the confessedly methods of carrying out the field test, methodical recommendations and manuals. Used such methods: scientific, special, comparatively analytical, regressive, informative-logical analysis and mathematical design. Maximal exit of standard seed from unit of area – 89.0 % got at sowing of sort Pivdennyy with the width of spaces between rows 45 see and bringing of nitric fertilizer by the dose of N 60 . On this variant got the most productivity of standard seed – 413 kg/hectare.
