Evaluation of Optimum and Economical Dose of Fertilizer for Groundnut Variety SP-2000

Abstract

Studies were carried out on different doses of NPK fertilizers applied to groundnut variety SP-2000 sown at Agriculture Research Station (N) Mingora, Swat to evaluate the optimum and economical dose of fertilizer for groundnut cultivation in the area. Based on yield and yield components data, it was concluded that treatment T2 (25:60:60  N:P₂O₅:K₂O kg/ha) gave the highest pod yield of 2490 kg/ha followed by treatment T6 (50:75:60 and T8 (50:60:75) with pod yield of 2319 and 2296 kg/ha, respectively, against the control T9 (00:00:00) which gave 1850 kg/ha. It is therefore suggested that these doses of NPK fertilizer should be recommended to the farmers in order to raise a healthy and good groundnut crop and ultimately get highest yields of pods.
