Abstract

A field experiment was carried out at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur during October, 2020-2021 in humid and sub humid condition of Rajasthan. The experiment was laid out in the Factorial Randomized Block Design with three replications and consist of two factors. The first factor including four genotypes of mustard i.e. ‘Bio-902’, ‘Giriraj’, ‘RH-0749’ and ‘NRCHB-101’ and second factor was four fertility levels i.e.75% RDF, 100% RDF, 75% RDF + Bio-fertilizer and 100% RDF + Bio-fertilizer. On the basis of performance highest seed, straw, biological yield, harvest index, and yield0 attributing characters i.e. primary, secondary, tertiary branches/plant, siliqua/plant, seed/siliqua and 1000 test weight exhibited by genotype ‘Giriraj’ and fertility levels. Further, among the various fertility levels maximum yield and yield attributes were significantly obtained under 100% RDF + Bio-fertilizer which was superior over rest of the treatments. However, significantly higher values of all the yield and yield attributing characters of mustard 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 (`/ha 103762, 97238), net return (`/ha 83347, 77148) and benefit-cost ratio (4.09, 3.84) was found with Indian mustard variety ‘Giriraj’ with application of 100% RDF+ Bio-fertilizer. Challenges to instability in yield and production because of appropriate donor source for major biotic stresses like alternaria blight, white rust, aphid pest attack, and abiotic stresses like drought, frost, salinity. Indigenous sources with rich quality of oil and seed meal are available but are poor yielders. Hence, genotype Giriraj with the application of 100% RDF + Bio-fertilizer were proved economically viable in mustard crop under prevailing agro-climatic conditions of Rajasthan. A big challenges in mustard is disease infestation sclerotina rot, orobanchae parasite, alternaria blight disease, non availability of quality seed, painted bug were identified and their management require the on farm technology.

Conclusion

The results of the investigation maximum seed yield (1812 kg/ha), gross return (` 103762 /ha), net return (` 83347 /ha) and B-C ratio (4.09) was obtained with genotype Giriraj further, maximum seed yield, gross return, net return and B-C ratio was realized under application of 100 % RDF + Bio-fertilizer compared to other fertility levels. Hence, genotype Giriraj with the application of 100% RDF + Bio-fertilizer were proved economically viable in mustard crop under prevailing agro-climatic conditions of Rajasthan.
