Abstract
The field study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Krishi Vigyan Kendra farm, Fatehabad, (Haryana) during Kharif 2020. The experiment was laid down with fourteen treatments, viz.T1 (Control), T2 (100% RDN (through urea)) + 50% RDN through FYM), T3 (75% RDN + 25% N through FYM), T4 (50% RDN + 50% N through FYM), T5 (25% RDN + 75% N through FYM), T6 (100% N through FYM), T7 (75% RDN + 25% N through Vermicompost), T8 (50% RDN + 50% N through Vermicompost), T9 (25% RDN + 75% N through Vermicompost), T10 (100% N through Vermicompost), T11 (75% RDN + 25% N through Poultry manure), T12 (50% RDN + 50% N through Poultry manure), T13 (25% RDN + 75% N through Poultry manure) and T14 (100% N through Poultry manure). Different nitrogen sources affected the yield and yield attributes variably. Highest (56.90, 90.07, 95.42 cm) and lowest (46.63, 77.37, 84.02 cm) plant height was observed in treatments T2 and T1 at 30 DAT, 60 DAT and harvest stage, respectively. The number of tillers varied from 166.14 (T1) to 205.15 (T2), 213.00 (T1) to 372.17 (T2) and 205.90 (T1) to 364.47 (T2) m-2 among different treatments at 30 DAT, 60 DAT and harvest stage, respectively. Highest grain yield (44.61 q ha-1) was observed in T2 and lowest (28.55 q ha-1) in T1. Treatment T6 and T1 showed highest and lowest straw yield with 52.28 and 32.93 q ha-1, respectively. Higher biological yield (96.88 q ha-1) was recorded with treatment T2 while lowest was recorded with treatment T1 with 61.48 q ha-1. Highest (46.99%) and lowest (43.18%) harvest index was observed in T6 and T1, respectively. In the treatments where N was applied either through manures alone or in combination with chemical fertilizer (urea), highest growth parameters (plant population and Plant height), yield and yield attributes (number of tillers, test weight) was observed higher in poultry manure as compared to vermicompost and FYM.
