ABSTRACT
Nitrogen (N) fertilization mostly determines the productivity of a crop. The supply of N can be ensured in both inorganic and organic means. Slowly released organic N can be combined with inorganic N to minimize the detrimental effect of chemical fertilizers to environment as well as to ensure the sustainable production. To observe the response of baby corn in integration of organic and inorganic N field experiments were conducted in N deficit soil in consecutive winter and summer. There were five nutrient levels as treatment in the experiment. The treatments used in the winter season were T1=N 0 kg + CD 15 t ha-1, T2=N 60 kg + CD 15 t ha-1, T3= N 90 kg + CD 10 t ha-1, T4= N 120 kg + CD 5 t ha-1 and T5= N 150 kg + CD 0 t ha-1 while in the summer season T1=N 30 kg + CD 15 t ha-1 varied and others remained same as in the winter season. The lowest cob yield without husk was found where minimum inorganic N was combined with organic N in both seasons. Plant received only N from inorganic source represented highest cob yield. Statistically similar yield was also obtained from one combination of inorganic and organic N (120 kg N + 5 ton CD ha-1), where the rate of inorganic N was 20% lower than that of sole inorganic N source. Between seasons, significantly positive yield response was recorded in winter irrespective of nutrient levels. Therefore, one fifth of inorganic N application can be minimized in terms of integrated N management from organic and inorganic sources without affecting potential yield of baby corn.
