Nutritional requirement for horsogram (Dolichos biflorus Roxb.)

Abstract

A field experiment was conducted at the college of Agriculture, Vellayani during 1932 to study the effect of three levels each of nitrogen (0.15 and 30 kg/ha), phosphorus (0. 25 and 50 kg P2Os/ha) and potassium (0.20 and 40 k2O/ha) on growth, yield and quality of horsegram. The trial was conducted as a 3 partially confounded factorial experiment with two replications. Application of nitrogen phosphorus and potassium had profound influence on all growth characters like height of plant* number of functional leaves and branches per plant and leaf area index. The highest nodule count was obtained by the application of 15 kg N 25 kg Pg 5 and 20 kg KO per hectare while tho dry weight of nodules per plant was maximum at 15 kg N 50 kg 40 kg K2O per hectare
