abstract
The objective of the study was to evaluate the growth response of mungbean [Vigna radiata (L.)] cultivars subjected to different levels of applied N fertilizer. To achieve the aim, an experiment conducted in the experimental field of University Research Farm, Rama University Mandhana, Kanpur 209217 (U.P.). The soil of the study area was basic in reaction, salt free, medium textured having low organic matter & total N contents. Three different cultivars of mungbean viz., (IPM 02-3, PDM-139, IPM 410-3) grown in kharif season for one consecutive years i.e., 2023. Three different levels of RDF applied @ 75%, 100% and 125% ha^-1. While, a constant dose of P₂O₅ and K₂O also applied to each N level (except control, zero). Urea fertilizer used as a source of N, while DAP and MOP as sources of P & K, respectively. The plot size kept as 21 m² (7x3), and arranged in a Spilt plot design (SPD). Results showed that different fertilizer levels did significantly (p<0.05) influence most of the growth attributes of the mungbean. Maximum plant height (63.51 cm), dry matter plant^-1 (9.46 g) and leaf area index (6.84) in 125% RDF. Whereas number of branches plant^-1 (3.49), yield (9.20 q ha¹) recorded for plants subjected to highest 100% RDF ha^-1. Similar responses toward also noted for various cultivars of mungbean. Maximum plant height (61.75 cm), dry matter accumulation (9.89 g), number of branches (3.45), leaf area index (6.95), number of root nodules plant^-1 (15.90), number of pod plant^-1 (23.04), number of grain pod^-1 (7.95), test weight (41.21 g), grain yield (9.26 q ha^-1), strow yield (26.18 q ha^-1), and biological yield (36.11 q ha^-1) recorded for IPM 02-3. Whereas, the maximum number of flower initiation days (35.77) in PDM139. But length of pod (8.39 cm) obtained for mungbean cultivar IPM 410-3.
