Groundnut Response to Boron and Molybdenum
As micronutrients required by the plants in a small amount but it perform different function in different plants. Micronutrients play an important role in the phsyiomorphological characteristics of many crops especially in leguminous crops. The aim of this review was about to study the role of micronutrients like boron and molybdenum in growth and yield parameters of groundnut or peanut plant as well as in nutrients concentration and uptake by the plant. Boron and molybdenum has the ability to improve yield and yield parameters of peanut plant. Several results showed that root nodulation, nodules numbers per plant and nitrogen fixation in groundnut plant were significantly improved while applying boron and molybdenum fertilizers. Molybdenum involve in nitrogenaze an enzyme which is responsible for biological nitrogen fixation which further improve nitrogen content of the soil. Furthermore, increasing level of boron and molybdenum showed significant increased in the concentration of micronutrients (B and Mo) in both plant and soil. As several researcher found earlier that application of boron and molybdenum significantly affect nutrients uptake by the plants. Boron and molybdenum availability of soil depends upon on soil type and soil pH, some soil type have boron and molybdenum deficiency but these deficiency can be recovered by the application of these nutrients to the plant which can be helpful in the uptake of nutrients from the soil and the soil status also improved. Micronutrients can be applied to the plant in two ways soil application and foliar application but the foliar method is the most efficient way of micronutrients application.
