The present study entitled “Influence of zeolite and nitrogen levels on grain yield and nutrient uptake of maize grown in red soils,” was a pot culture study carried out in Green House of Soil Science department, College of Agriculture, Rajendranagar, PJTSAU, Hyderabad, Telangana state during kharif, 2018-19. The treatments consists of combinations of 3 levels of nitrogen (100, 150, 200 kg ha-1) and 4 levels of zeolite (0, 2.5, 5, 7.5 t ha-1) along with a control in which only P and K were applied and they were replicated thrice in a factorial completely randomized design. The results revealed that application of 200 kg ha-1 nitrogen in combination with 7.5 t ha-1 zeolite (Z7.5 N200) increased grain yield of maize which was on par with the treatment receiving 200 kg ha-1 nitrogen in combination with 5 t ha-1 zeolite (Z5.0 N200). The combination of 7.5 t ha-1 zeolite with 200 kg ha-1 nitrogen (Z7.5 N200) have significantly increased N, P, K uptake of maize compared to rest of the treatments.
