A field experiment was conducted at Agricultural College Farm, Bapatla, Andhra Pradesh on sandy upland soils during post-monsoon, 2018. The experiment consisted of four levels of nitrogen and four population densities laid out in randomized block design with factorial concept. Nutrient content significantly increased with increase in nitrogen levels and higher content of N, P, K, Zn and Fe were obtained with 90 kg N ha-1 which was significantly on par with 60 kg N ha-1. Nutrient content was higher with wider spacing of 30 x 10 cm, which was on par with 25 x 10 cm. The microbial population was significantly influenced by levels of nitrogen fertilization and significantly superior population of fungi, bacteria and actinomycetes was found with 90 kg N ha-1. Microbial responded significantly to population densities and significantly higher microbial count was obtained with 15 x 10 cm spacing.
