Assessment of the Quality and Productive Performance of Brassica juncea L. (Indian Mustard) in Response to Varied Growth Regulator Treatments and Spatial Factors

Production quality plays a crucial role in individual well-being and national economic prosperity. Indian mustard (Brassica juncea L.), the third most vital oilseed crop globally and the second most cultivated in India after groundnut, faces challenges due to shrinking land availability and improper fertilizer use. These issues reduce mustard yields by limiting essential micronutrient uptake. This study investigated the impact of agrochemicals on mustard crops grown in reduced row spacing to boost yield. Mustard plants responded variably to boron, sulfur, and cytokinin foliar applications. The research assessed how these nutrients influence the crop's growth, development, and yield under limited spacing conditions. Boron (0.5-1.5%) and sulfur (0.10-0.25%) were applied individually and in combination with cytokinin (0.003-0.0045%) as a foliar spray using a split-plot design. Morphological, physiological, biochemical, and yield-related parameters were carefully monitored. The application of these agrochemicals enhanced the mustard crop's growth, physiology, and quality, improving production quality under limited space conditions..
