Effect of integrated nutrient management on soil fertility, uptake of nutrients and yield of maize in southern tansitional zone of Karnataka.

摘要

Higher fertility levels were observed in T₈ which received 75 kg N through inorganic fertilizer, 25 kg N through compost, Azospirillum, recommended P and K with French bean intercrop. Similarly, higher nitrogen uptake (139 kg/ha), phosphorus uptake (58 kg/ha) and potassium uptake (131 kg/ha) and highest grain and stover yield of maize (4,689 kg/ha and 6.68 t/ha, respectively) was observed in T₈. Addition of compost, French bean green manure and Azospirillum favored higher fertilizer use efficiency when applied in combination, thus leading to higher yields.
