Abstract
A field experiment was conducted in rice during Kharif, 2015 at Agricultural College Farm, Mahanandi to study the influence of different levels of potassium either alone or in combination with green manure on plant height, yield, yield attributes and economics of rice. The results revealed that plant height, yield and yield attributes were increased with increasing levels of potassium up to 120 kg K2O ha-1. However, there was no statistical difference between three levels of K (40, 80 and 120 kg K2O ha-1) in increasing plant height, yield and yield attributes. Application of green manure in situ (GM) in combination with K recorded higher values of above mentioned parameters than when applied alone. The higher plant height, yield and yield attributes were obtained with GM+120 kg K2O ha-1 which was on a par with GM+80 kg K2O ha-1 and GM+40 kg K2O ha-1. However, the highest gross returns, net returns and B: C ratios were recorded with GM+120 kg K2O ha-1 followed by GM+80 kg K2O ha-1 and GM+40 kg K2O ha-1.
