Abstract
The present investigation was carried out in kharif season 2022-23 at Agronomy Research Farm of Chandra Bhanu Gupta Krishi Snatakottar Mahavidyalaya, Bakshi ka Talab, Lucknow (U.P). The 8 treatments comprised of T1- RDF(IF), T2- 100% RDF+25 kg ha-1 ZnSO4 (B), T3-100% RDF+2 foliar spray of ZnSO4, T4- RDF+50 kg ha-1 FeSO4 (B),T5-100% RDF+ZnSO4 25 kg ha-1 (B) + FeSO4 @ 50 kg ha-1 (B), T6- 75% RDF (IF)+25% RDN (FYM), T7- 50% RDF (IF)+50% RDN (FYM),T8-100% RDF through FYM were laid out in Randomized Block Design (RBD). The soil was silty-loam texture with slightly alkaline pH 8.1, organic carbon 0.70 %, available nitrogen 270.00 kg ha-1, available phosphorus 27.0 kg ha-1, and available potash 262.0 kg ha-1 during 2022-2023. The values of growth contributing characters viz., plant height (cm), number of tillers per m2 (439.73), dry matter accumulation (g m -2 ) (829.62), at harvest and significantly highest (6.33) leaf area index (LAI) was recorded under 100% RDF + 2 foliar spray of ZnSO4 and yield attributes and yield like number of effective tillers per m-2 (200.66), panicles weight (g)(4.51), length of panicle (cm) (28.33), number of grains panicle-1 (175.33), test weight (g) (29.10), grain yield (47.85), straw yield (q ha-1 ) (64.75) of rice were significantly higher under T3- 100% RDF + 2 foliar spray of ZnSO4 compared to other treatment. The nitrogen content (%), and its uptake (kg ha-1), and protein content (%), and its production (kg ha-1) in grain and straw was significantly higher under T3-100% RDF + 2 foliar spray of ZnSO4. The Fe and Zn content (mg kg-1) and its uptake (kg ha-1) in grain and straw was higher under T3-100% RDF + 2 foliar spray of ZnSO4. Economics analysis viz gross return (123514), net return (84107) and benefit cost ratio (2.13) was recorded highest with T3-100% RDF + 2 foliar spray of ZnSO4 while lowest with T8- 100% RDF through FYM. Thus for obtaining better yield and profit apply T3-100% RDF + 2 foliar spray of ZnSO4.
