abstract
Groundnut (Arachis hypogaea)is one of the most important cash crops as it is a low-priced commodity but a valuable source of all the nutrients for human nutrition. The contribution of micronutrients like boron and zinc has their pivotal role in determining the yield of groundnut., therefore the experiment was laid out to venture the effects of boron and zinc on quantity parameters. Six groundnut genotypes (TG 26, TG 51, TG 71, TG 72, BARC 150 and BARC 200) were tried with nine different treatment combinations with three levels of each of boron (boric acid) and zinc (zinc sulphate) [B₀ = no boron, B_L = boric acid @ 0.25% and B_H = boric acid @ 0.5%, Z₀ = no zinc sulphate, Z_L = zinc sulphate @ 0.5% and Z_H = zinc sulphate @ 1%]. All together treatments were: B₀Z₀ (T₁), B_LZ₀ (T₂), B_HZ₀ (T₃), B₀Z_L (T₄), B_LZ_L (T₅), B_HZ_L (T₆), B₀Z_H (T₇), B_LZ_H (T₈) and B_HZ_H (T₉). All yield parameters except the number of productive nodes per plant were substantially influenced by the foliar treatments of boron and zinc. The response of the genotypes to the different treatments was not uniform. TG 26, TG 51 and TG 71 performed substantially better in T₈ (BLZH), T₃ (BHZ0) and T₆ (BHZL), respectively than any other treatments including the control. Hence, with appropriate treatment of boron and zinc yield of groundnut can be enhanced and in some cases quality of the yield also can be augmented.
