Abstract:
A field study entitled “Effect of Varied Levels of Fertility, Zinc and Zinc Biofertilizer on growth attributes of Indian mustard {Brassica juncea (L.) Czern & Coss} Under Inceptisols of Southern” was conducted with 18 treatments at Rajasthan College of Agriculture, Udaipur during rabi 2020-21. All the growth attributes improve significantly with the application of 100% RDF, zinc fertilizer as well as zinc biofertilizer. Among fertility levels, the highest plant height of mustard recorded under application 100% RDF at 30 (40.21 cm), 60 DAS (195.30 cm) and at harvest (210.75 cm), significantly maximum dry matter accumulation at 30 (5.89 g plant^-1), 60 (26.01 g plant^-1), 90 DAS (34.53 g plant^-1) and at harvest (38.74 g plant^-1) and crop growth rate (0.670 g m^-2 day^-1) between 30-60 DAS. Whereas, among zinc levels application of 5.0 kg Zn ha^-1 recorded significantly higher plant height at 30 (38.84 cm), 60 DAS(186.10 cm) and at harvest (202.28 cm), maximum dry matter accumulation at 30 (5.17 g plant^-1), 60 (24.52 g plant^-1), 90 DAS (33.71 g plant^-1) and at harvest (37.28 g plant^-1) and crop growth rate (0.645 g m^-2 day^-1) between 30-60 DAS. Application of zinc solubilizer recorded significantly higher plant height and dry matter accumulation at all stages.
