Abstract

A field experiment to determine the optimum NPK requirement of groundnut (Arachis hypogees L) (variety M-13) was conducted at the Agricultural College Farm. Dopoil for the three years j. 1977. 1978 and 1979 during Kharif season. The results reves ed ther the N. P and K combinations viz.. 26:50:00, 25:50:25 and 25:50:50 kg/he gave significantly more dry pod yield of groundnut over 0:0:0 (control) 4:4:18 and 12 5:25:12 5 kg NPK/ha. Former treatment combinations were at per with each other, Highest dry pad yield (23.45 q/ha) was obtained due to application of 25 50:0 followed by 25:50:50 (23.21 q/ha) and 25:50.25 22.79 q/ha) MPK par hectare respectively. The per cant ineroase was in the range of 67.65 and 62 respectively in later three treat- mante overcontrol.
