Abstract:
A field experiment was conducted during (Rabi) season of 2020-21 at Research farm of SKUAST- J University Chatha, Jammu, India to study the effect of foliar application of seaweed extract, under different doses of NPK at various vegetative stage of wheat. Treatment comprised of seed priming with seaweed extract @ 3 ml/kg seed, seed treatment with seaweed extract @ 3 ml/kg seed, and control without seaweed extract in main plot, foliar application of seaweed extract @ 2 ml/litre water and 4 ml/litre water at tillering and heading stage in seven treatments control spired with water in sub plot and two graded levels of NPK viz., 75 and 100% recommended fertilizer in sub-sub plot laid out in a split-split plot design and replicated thrice. The result revealed that seed priming and treatment with seaweed extract did not show any significant influence on growth parameters of wheat, however, foliar application of seaweed extract in (T6) 4 ml/litre water at tillering and heading stage was observed significantly higher growth parameters after 30 DAS viz., leaf area index, dry matter accumulation, as compared to (F7) control. also statistically at par with (F5) foliar application of seaweed extract 2 ml/litre water at tillering and heading stage, on the other hand plant height and number of tillers showed non-significant effect. Among two graded level of NPK 100% significantly higher than 75% between all growths parameters at all stage except 30 DAS. As a final point the interaction effect was noted significantly maximum under (F6) foliar application of seaweed extract @4 ml/litre water at tillering and heading stage with 100% NPK, also at par with (F5) foliar application of seaweed extract @ 2 ml/litre water + 75% NPK.
