Effect of organic and inorganic fertilizers on growth attributes and yield of wheat varieties in intermediate zone of Jammu, Jammu and Kashmir

A field experiment was conducted to study the effect of organic and inorganic fertilizers on the growth attributes and yield of wheat varieties in intermediate zone of Jammu, Jammu and Kashmir during winter 2018-19 and 2019-20 at RegionalAgricultural Research Station Rajouri, Jammu and Kashmir. The study comprised 4 varieties (WH 1080, WH 1025, VL 907 and VL 967) in mainplots and 5 levels of nutrient combinations (N₁ : Control, N₂ : 100% RDF, N₃ : 50% RDF + 50% RDF through FYM, N₄ : 50% RDF + 50% RDF throughvermicompost (VC), N₅ : 50% RDF + 50% RDF through FYM + 50% RDF through VC + biofertlizers). The experiment was laid out in split plot design with three replications. The pooled mean (2018-19 and 2019-20) showed that plant height (98.9 and 99.8 cm) and dry matter accumulation per plant (22.3 and 26.6 g) at 150 DAS and at harvest respectively were found significantly highestin variety VL 907 over all the varieties. Leaf area index was highest (6.3 and 3.2) in VL 907 at 120 and 150 DAS respectively. Shoot length at 120 DAS (78.9 cm) and grain yield (4,891 kg/ha) were also observed highest in VL 907. Maximum plant height (100.2 and 101.7 cm) and dry matter accumulation per plant (22.9 and 26.0 g) at 150 DAS and at harvest respectively were recorded in RDF (100%) treatment. Leaf area index (6.1 and 3.0) was maximum in RDF (100%) at 120 and 150 DAS respectively. RDF (100%) also resulted in highest shoot length (79.1 cm) at 120 DAS and grain yield (4,757 kg/ha).
