Effect of Potassium Levels and Potassium Solubilizing Bacteria on Growth and Yield of Maize (Zea mays L.)

A field experiment was conducted during kharif 2020 at, Prakasam Krishi Vigyan Kendra (KVK), Jayaprakash Nagar, Jammikunta, Karimnagar District ? 505 122, Telangana State. To study the effect of potassium and potassium solubilizing bacteria on growth and yield of maize (Zea mays L.). The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. It was observed that T6 - K2O 40 gm + KSB 20 ml/ kg Soil (SA) + KSB 30 ml/ kg Seed (SI) 80 DAS was found to be the best treatment for obtaining growth and yield attributes such as Plant height (243.33 cm), Dry matter production (358.33 g/plant), No. cobs per plant (1.77), No. of grains per row (36.67), No. of rows per cob (16.00), No. grains per cob (586.72), Seed index (44.00 g), Grain yield (5.78 t/ha).
