Impact of Boron and Zinc on Vegetables: A Review

Abstract

Micronutrients are necessary for the development and continued existence of plant life, as well as the nourishment of crops. Boron and zinc are found to have beneficial effects on the growth, production, and quality of a wide variety of crops, such as tomatoes, chilies, brinjal, cauliflower, broccoli, okra, and carrots, amongst many others. The different studies show that boron in soil and foliar increases tomato vegetative growth and production. Boron 2 kg/ha in the soil and 150 ppm or 3.8 mg/L foliar spray improve yield. According to investigations, adding boron to chilli at 1-3 kg/ha increases yield. Boron, vermicompost, and magnesium are also claimed to increase yields in significant amount. The applying boron on brinjal produced a significantly higher yield, 26% yield increase over control. Applying borax in the soil and foliar concentration at 100 ppm increases cauliflower output and improves its vegetative characteristics. 100 ppm zinc foliar spray increases production by 150-200% in tomato. However, zinc treatment improves vegetative development and reproductive traits, directly increasing tomato output. Zinc applied at 0.5 to 0.75 % to chili increased overall yield significantly.it is also found that application of the zinc in bottle gourd, broccoli and okra found to be beneficial in increasing the overall production which will cause the benefit to the farmer. Concluding that the application of boron and zinc on vegetables found to be significantly beneficial in various ways as per discussed in the review.
