Effect of Organic Manures, Sulphur and Foliar Application of Micronutrients (Zinc and Boron) on Growth and Yield of Mustard (Brassica juncea L.)

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.

Effect of Nutrients Management Management Practices on Growth and Yield Parameters of Gobhi Sarson (Brassica napus spp. napus).

“…This may be due to provision of macro and micro nutrients at latter stages which might have improved accumulation of assimilate in seeds and thus resulting in heavier seed. The results of this investigation are in consonance with the findings of Ramya et al [22]. As compared to 100% NPK, skipped application of any primary nutrient significantly decreased the Gobhi sarson seed yield.…”

Correlation Analysis between the Contents of Zinc (Zn) in Soil and Corn Seeds on Lime Main Material

“…Soil pH levels also play an important role; acidic soils generally make Zn more available, whereas alkaline soils tend to bind Zn in a form that is not available to plants [21] . In addition, agricultural practices, including fertilization and soil management, can affect Zn availability, and unbalanced fertilization can cause Zn deficiencies or excesses [22] . Climatic conditions such as high rainfall causing leaching of Zn from the top layer of soil and lower temperatures reducing soil microbial activity that aids Zn mobilization also affect Zn availability.…”
