Abstract: A field experiment entitled was conduct under title as, “Effect of organic and inorganic sources on soil properties, yield and growth of spring maize (
Zea mays L.)” at Research and Advance Studies Farm, Department of Agricultural Sciences, Sant Baba Bhag Singh University, Khiala, Jalandhar during spring 2023. The field experiment was designed in Randomized Block Design, with 7 treatments and 3 replications. The field experiment was designed to study the influence of biofertilizer on soil properties, yield and growth of maize.
It was observed that treatment T4 (Seed treatment with 160 ml of PSB + 100% N and P) shows the superior after 90 DAS under growth parameters (plant height 160.6 cm, number of leaves 11.1, LAI 5.42) but it was statistically similar with the treatment T6 (Seed treatment with 220 ml of PSB + 100% N and P). T7 (Soil application of 450 g Azotobacter + FYM + 100% N and P) produced maximum grain yield of 61.5 q ha-1. Similar results was observed for the number of cobs per plant, number of grains per cob, 1000-grain weight, cob length, cob girth, stover yield, etc. So, it was observed that growth parameters, grain yield and yield attributes was significantly increased with applications of biofertilizers. On the other hand applications of biofertilizer increase the available nutrients status in soil, but there is no significant effect on soil organic carbon percentage.
