Abstract
Phosphorus (0,23,46 or 69 kg P20S ha') and potassium (0,50, 100 or 150 kg K20 ha') were applied in different combinations to pea cv. Samrina Zard at the time of seed bed preparation. Nitrogen level (46 kg N ha') was kept constant and applied in two split doses, i.e. half at the time of sowing while the other half was applied before flowering. Vine length, number of pods plant", pod length, number of grains pod" and green pod yield were significantly affected by the levels of P20S. Number of grains pod" and green pod yield were maximum at the highest dose of P20S (69 k~ ha'). However, vine length, number of pods plant" and pod length increased up to the level of 46 kg P20S ha' . Application of K20 to the crop up to the dose of 100 kg ha·1 had significant positive effect on all the parameters studied, beyond this dose further application of K20 was ineffective. As combined effect of P20S and K20 is concerned, it significantly influenced the pod length and green pod yield. Maximum pod length was attained when 69 or 46 kg P20S ha" was applied in combination with 100 or 150 kg K20 ha'. Green pod yield was maximum at 69 kg P20S na" x 100 or 150 kg K20 ha'. Key words. Green pod yield, Pisum sativum , plant nutrition, vine growth, yield components.
