Full Text:

Abstract

At cultivation of a clover meadow on luvisol loamy sand soil it is established that its efficiency depends on weather conditions, a hay crop and doses of mineral fertilizers. Productivity of green weight of a clover was formed at level of 5,05-6,93 t/ha, hay - at level of 0,97-1,23 t/ha. The maximum productivity of 693 t/ha, gathering of solid of 1,04 t/ha and gathering of fodder units of 1,46 t/ha are received at application Р70К120 and entering N30Р70К120 under the predecessor a winter rye. The maximum recoupment of 1 kg o. s. fertilizers in green weight of 58 kg it is received at application of fertilizer system Р40К80. On the average for three years in a variant with optimum productivity the following specific carrying out with 1 t green weight: nitrogen 3,6 kg, phosphorus 1,0, potassium 6,5, calcium 1,7, magnesium of 0,8 kg and with 1 t hay: nitrogen 20,5 kg, phosphorus 5,6, potassium 36,7, calcium 9,4, magnesium of 4,7 kg.
