Response of groundnut (Arashis hypogaea (L.) to phosphorus and potassium under different water management practices

Abstract

The study revealed tho favourable Influence of frequent irrigations on growth characters like pleat height, number of branches end loaves per plant, MI, dry matter production per pleat sad number sad dry weight of nodules par plant end through these characters, haulm yield. The yield end yield attributes also showed a significant increase at higher levels of irrigation. The highest yield of 2533 kg/ha was obtained by scheduling irrigation at 0.9 1H/GPS ratio. In general a decrease in phosphorus content could- be observed at higher levels of irrigation. Frequent irrigations helped to increase oil content, oil yield end kernel protein yield par hectare. In general, the nitrogen end potassium content in tho plant parts were less affected by irrigation. More frequent irrigations had increased nitrogen. Phosphorus and potsssium uptake by the crop
