Effect of different irrigation and fertility levels on dynamic growth and yield of late sown wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted at Kumarganj, Faizabad during Rabi season of 2016 to evaluate the effect of different irrigation and fertility levels on dynamic growth and yield of late sown wheat (Triticum aestivum L.). Results revealed that the irrigation levels significantly affected grain and straw yields as well as most of the growth and their attributes of wheat. Four irrigations recorded highest plant height (74.63cm), number of tillers (81.33 m-1 row), dry matter accumulation (93.16 g m-1 row) at harvest stage and leaf area index (3.85) at 90 DAS as well as higher grain (23.12 q ha-1) and straw yield (32.37 q ha-1) over two and one irrigation. Among fertility levels application of 25% more than RDF of NPK fertilizer recorded highest plant height (69.65cm), number of tillers (78.41), dry matter accumulation (82.80 g m-1 row), leaf area index (3.50) as well as grain (19.65 q ha-1) and straw yield (29.64 q ha-1) over 100% RDF and 25% less than RDF of NPK, respectively.
