Abstract:
A field experiment was carried out at Agricultural College Farm, Bapatla during rabi 2021. In order to study the impact of crop residue incorporation and potassium releasing bacteria (KRB) on the growth and available nutrient status of maize (Zea mays L.) The experiment was laid out in a Randomized Block Design with ten treatments replicated thrice. The treatments comprised of T1: Control, T2: KRB alone, T3: 50% RDK+KRB, T4: 75% RDK+KRB, T5: 100% RDK alone, T6: 100% RDK+ KRB, T7: 50% RDK+50% K through rice straw incorporation, T8: 75% RDK + 25% K through rice straw incorporation, T9: 50% RDK + 50% K through rice straw incorporation + decompo A & B, T10:75% RDK + 25% K through rice straw incorporation+ decompo A & B. The results revealed that application of 100% RDK along with KRB and 75% RDK + 25% K through rice straw along with decomposers showed the significant effect on plant height, drymatter production, grain and stover yield and available potassium status in soil found superior over the rest of treatments.
