Evaluation of different varieties, seed rates and row spacing of groundnut, planted under agro-ecological conditions of malakand division

Abstract

Studies were carried out to evaluate different varieties, seed rates and row spacing of groundnut planted at the Agriculture Research Institute (N) Mingora, Swat to find the most suitable seed rate and row spacing for cultivation of different promising groundnut varieties in the area. Based on yield and yield components data, it was concluded that among different varieties, the highest pod yield of 3738 kg ha-1 was recorded for variety SP-2002. Among different seed rates, the highest pod yield of 3808 kg ha-1 was recorded for S3 (60 kg acre-1), while among different row spacing, highest pod yield of 3739 kg ha-1 was recorded for R1 (30 cm). The interaction between varieties, seed rates and row spacing revealed that highest pod yield of 5784 kg ha-1 was recorded for treatment # T7 (var. SP-2000, 60 kg acre-1, 30 cm) at 5% level of significance followed by treatment # T16 (var. SP-2002, 60 kg acre-1, 30 cm) and # T13 (var. SP-2002, 40 kg acre-1, 30 cm) with pod yield of 5312 and 5284 kg ha1-, respectively. It is therefore suggested that variety SP-2002 may be recommended to the farmers for cultivation in the area at a seed rate of 60 kg acre-1 and row spacing of 30 cm. © 2007 Asian Network for Scientific Information.
