Abstract

The present investigation was under taken during kharif 2011 season, to study the effect of long-term application of manure and fertilizers on pod yield, haulm yield and nutrient uptake of groundnut crop. The experiment was initiated in the year 1981 during kharif season at Regional Agricultural Research Station, Tirupati, Andhra Pradesh, India. The results revealed that application of NPK (20:10:25 kg ha-1) + gypsum (250 kg ha-1) + ZnSO4 (25 kg ha-1) recorded significantly higher pod and haulm yield in groundnut. Further, the uptake of N, P, K, Ca, Mg and S in haulm, kernel and shell at harvest in the treatment NPK+ Gypsum + ZnSO4 was found to be at par with NPK (20:10:25 kg ha-1)+gypsum (250 kg ha-1). The results revealed that there is significant influence of long term use of manure and fertilizers on the productivity of rainfed groundnut and soil nutrient status in alfisols of Andhra Pradesh.
