Onion is valued for its bulbs having characteristic odour, flavor and pungency. It is an export oriented vegetable and earns a valuable foreign exchange to our country. Boron helps in the uptake of calcium and encourages efficient utilization of calcium in plants, it also helps in protein synthesis. Zinc is a constituent element of number of enzymes i.e. ironic anhydrate of growth hormones (auxins). It enhances heat and frost resistance of plant and affects the uptake of phosphorus by plants. It also acts as a catalyst in chlorophyll formation. Micronutrients help increase the efficiency of the use of macronutrients. Micronutrients have a great role in the fertilizer program to achievement higher and sustainable crop yields. Unfortunately micronutrients have received less attention in fertilizer management research, development and extension. Growers should carefully follow recommendations for micronutrients to avoid unnecessary costs and possible toxic effects or deleterious interactions with other nutrients. The literature available on response of zinc and boron in relation to growth, yield and quality of onion under following heads: 1. Effect of zinc and boron on growth and yield of onion. 2. Effect of zinc and boron on yield of onion. 3. Cost economics analysis.
