Abstract:

A field experiment was conducted during the kharif, 2018 at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.), to study the “Nutrient management in kharif rice (Oryza sativa L.) through inorganic and organic sources for enhancing productivity and profitability in konkan region of Maharashtra.” The experiment was laid out in split plot design which comprising of 25 treatment combinations replicated thrice. Main plot treatment consisted of five levels of nitrogen through urea (N1-100 per cent RDN, N2-75 per cent RDN, N3-50 per cent RDN, N4-25 per cent RDN and N5-No fertilizer (control) and sub-plot treatment comprised of five levels of nitrogen through FYM (M1-100 per cent RDN, M2-75 per cent RDN, M3-50 per cent RDN, M4-25 per cent RDN and M5-No FYM (control).The experimental plot was sandy clay loam in texture, moderately acidic in reaction with very high in organic carbon content. Soil was low in available nitrogen, low in available phosphorus and moderately high in available potassium. The experimental results revealed that application of 100 per cent RDN through urea recorded significantly higher growth parameters and yield attributes resulting into significantly more grain and straw (q ha-1) than remaining levels of nitrogen. The highest gross returns of Rs.1,25,685 ha-1, net returns of Rs. 6,974 ha-1 and benefit to cost ratio of 1.06 were obtained due to application of 100 per cent RDN through urea. Among the levels of nitrogen through FYM, 100 per cent RDN (M1) recorded significantly higher value of growth parameters and yield attributes which resulting into significantly more grain and straw yields (q ha-1) than remaining levels of nitrogen under the investigation. Significantly highest net monitory returns of Rs. 22,650 ha-1 and B:C ratio of 1.30 registered under the treatment (N5) No FYM (control) than other higher levels of FYM during year of experimentation. Among the different treatment combinations, the highest net returns and B:C ratio of Rs. 32, 749 ha-1 and 1.41, respectively were obtained under treatment combination of (N1M5) i.e. 100 per cent RDN through urea with no FYM.
