Abstract:

A field experiment “Effect of Genotypes under Varying Fertility Levels and Bio-fertilizer Inoculation on Yield, Yield Attributes and Economics of Mustard {Brassica juncea (L.) Czern & Coss.}’’ was carried out at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur, Rajasthan during rabi season of 2020-2021 in factorial randomized design (RBD). However, the treatment comprised of four genotypes i.e. Bio-902 (V1), Giriraj (V2), RH-0749 (V3) and NRCHB-101 (V4) and four fertility levels i.e. 75% RDF (F1), 100% RDF (F2), 75% RDF + Bio-fertilizer (F3) and 100% RDF + Bio-fertilizer (F4). Results clearly revealed that the entire yield, yield attributes and ultimately on economics were immensely influenced by genotypes and fertility levels. Yield and yield attributes i.e. seed, straw, biological, harvest index, primary, secondary, tertiary branches/plant, siliqua/plant, seed/siliqua and 1000 seed weight were increased with increasing the fertility levels. In among genotypes, Giriraj (V2) recorded significantly higher value of yield component i.e. seed, straw, biological, harvest index and yield attributes i.e. siliqua/plant and seed/siliqua. Further primary branches, tertiary branches and 1000 seed weight which were statistically at par with NRCHB-101(V4), Bio-902 (V1) and NRCHB-101(V4), respectively and significantly superior to RH-0749.Among the various fertility levels maximum yield and yield attributes were significantly obtained under 100% RDF+ Bio-fertilizer (F4) which was superior over rest of the treatments. However, significantly higher values of all the yield attributes and yield of mustard crop were observed with genotypes ‘Giriraj’ followed by NRCHB-101, Bio-902 and RH-0749 and fertility level 100% RDF + Bio-fertilizer as compare to other treatments. Relative economic analysis for crop cultivation indicated that the maximum gross return (₹/ha103762, 97238), net return (₹/ha83347, 77148) and benefit: cost ratio (4.09, 3.84) was found with Indian mustard variety ‘Giriraj’ with application of 100% RDF+ Bio-fertilizer.
