Effect of nitrogen and phosphorus levels

An experiment entitled "Effect of nitrogen and phosphorus levels on yield and quality of baby corn" was carried out in kharif season of 2014-15 at the Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The experiment was laid out in Factorial Randomized Block Design with three replications and twelve treatment combinations with factor A viz. nitrogen(N) i.e. 150 kg ha-1 (N1), 175 kg ha-1 (N2), 200 kg ha-1 (N3) and 225 kg ha-1 (N4) factor B phosphorus (P) i.e. 50 kg ha-1 (P1), 75 kg ha-1 (P2) and 100 kg ha-1 (P3). Growth and yield parameters were significantly influenced by nitrogen levels, treatment with application of nitrogen 225 kg ha-1 recorded significantly higher plant height, no. of leaves, leaf area index, total dry matter accumulation per plant, chlorophyll content. Minimum days to 50% tasseling, silking and maximum cob emergence were recorded at 225 kg ha-1 of nitrogen application. Number of cob per plant, cob length, cob diameter, cob weight with and without husk also significantly influenced by N3 (200 kg ha-1) levels of nitrogen application.
