Abstract:A field experiment was conducted during the summer season of 2021 at ZAHRS, Brahmavara, KSNUAHS, Shivamogga to study the "Effect of potassium and zinc solubilizing microorganisms on yield and quality of groundnut (
Arachis hypogaea L.) in Coastal Zone of Karnataka.” Field experiment consisted of eight treatments
viz., absolute control (T
1), RDF (T
2), RDF with KSB and ZnSB either alone (T
3 and T
4) or in combination (T
5), RDNP + 75% RD of K and ZnSO
4 + seed treatment with KSB +ZnSB (T
6), RDNP + 50% RD of K and ZnSO
4 + seed treatment with KSB +ZnSB (T
7) and RDNP + seed treatment with KSB + ZnSB (T
8) are replicated thrice was laid out in RCBD.
Among treatments tried, significantly higher pod yield (1675 and 1654 kg ha-1), kernel yield (1245 and 1224 kg ha-1), were recorded with recommended dose of fertilizer + seed treatment with KSB + ZnSB (T5) and RDNP + 75% RD of K and ZnSO4+ seed treatment with KSB + ZnSB (T6), respectively. The better values of these indices in T5 and T6 resulted in higher protein yield (333.04 and 325.95 kg ha-1) and oil content (613.79 and 598.54 kg ha-1), respectively, recorded in treatments T5 and T6. Seeds treatment with both potassium and zinc solubilizing microorganisms in addition to state recommended nutrient practices for groundnut resulted in better pod yield, protein yield and oil yield, over package of practices.
