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.
