Nitrogen use effectiveness and life cycle of root knobs in Alfalfa after various mineral treatment and soil development Paper ID: BJESM-01-10-2019-121
Abstract : Nitrogen use productivity and life cycle of root knobs in horse feed after various mineral treatment and soil development practices were examined. Field preliminary was directed in the Organization of Scrounge Yields, Pleven, Bulgaria on filtered chernozem subsoil type and no water system. The following medicines were tried: I) for preparation as pursues: N0P0K0 (control); N60P100K80 (an acknowledged innovation); N23P100K35 (nitrogen was connected 1/2 in first year of developing and 1/2 in third year); N23P100K35 (nitrogen was provided pre-planting); N35P80K50, and Amophose - 250 kg/ha, determined at treating rates N27P120K0; ii) for soil development as pursues: soil losing 10-12 cm, furrow at profundity 12-15 cm, 22-24 cm (an acknowledged innovation), 18-22 cm and 30-35 cm. It was discovered that dirt development and mineral preparation had impact on nitrogen use productivity and life cycle of root knobs in Hay. Nitrogen use effectiveness was observed to be most astounding at N23P100K35 and furrow at the profundity of 22-24 cm. Life cycle of root knobs was the longest at N35P80K50 and furrow at the profundity of 18-22 cm. The better root mass to knob number proportion was found at N23P100K35 and furrow at the profundity of 22-24 cm.
