Abstract

A field experiment was performed on growth and yield of mustard (Brassica juncea L.)” variety NRCHB-101 at Agricultural college, PJTSAU, Polasa, Jagtial, during spring 2021-2022. The soil of the experimental site was sandy clay loam in texture. The present research work was tested in randomized block design with 11 treatments comprising of different nutrient management practices i.e. T1: Control, T2: 100% NPK @60-40-40 NPK Kg ha-1, T3: 100% NPKS @60-40-40-40 NPKS Kg ha-1, T4: 100% NPK+ Vermicompost @2.5 t ha-1, T5: 100% NPK+ FYM @5 t ha-1, T6: 100% NPK+ Foliar spray of 0.5% Zinc-EDTA at flower initiation and at 50% flowering, T7: 100% NPKS + Foliar spray of 0.5% Zinc-EDTA at flower initiation and at 50% flowering, T8: 100% NPK + Foliar spray of 0.2% Boric acid at flower initiation and at 50% flowering, T9: 100% NPKS + Foliar spray of 0.2% Boric acid at flower initiation and at 50% flowering, T10: 100% NPK+ Foliar spray of 0.5% Zinc-EDTA and 0.2% Boric acid at flower initiation and at 50% flowering and T11: 100% NPKS+ Foliar spray of 0.5% Zinc-EDTA and 0.2% Boric acid at flower initiation and at 50% flowering. The results revealed that significantly higher plant height (174 cm), Leaf area index (LAI) (2.94), No. of primary branches plant-1 (10), No. of secondary branches plant-1 (19.3) dry matter accumulation (4260 kg ha-1) No. of siliquae plant-1 (189.33), seeds siliqua-1 (16.13), test weight (5.97 g), seed yield (1271 kg ha-1) and stover yield (3141 kg ha-1) with the application of 100% NPKS along with  foliar spray of 0.5% Zinc-EDTA and 0.2% Boric acid at flower initiation and at 50% flowering.
