PATTERN OF DRY MMTER AND NUTRIENT ACCUMULATION IN WHEAT VARIETIES AT DIFFERENT STAGES OF GROWTH AS INFLUENCES BY LEVELS OF POTASSIUM - I. EFFECT ON DRY MATTER AND

摘要

A pot experiment was conducted under net house condition to study the effect of potassium on dry matter, N, P, K and S accumulation at different stages of wheat crop. The results showed that dry matter and grain yield as well as accumulation of N, P,K and S were found significantly highest with K_(90) followed by K_(120) The uptake of N, P, K and S by wheat shoot, root and grain was increased with advancement of crop age. All the five varieties of wheat (Lok-1, GW-496, GW-27.3, GW-1139 and HI-8439)revealed significant diversity in view of N, P, K and S uptake by wheat shoot, root and grain.
