Study of soil properties under integrated nutrient management in irrigated condition in Allahabad

Abstract

Field experiment was conducted during Rabi 2005-06 and 2006-07 at the crop Research Farm, Department of Soil and Agricultural chemistry Sciences, Allahabad Agricultural Institute – Deemed University, Allahabad, to study the performance of winter maize as affected by inorganic and organic use of nutrients on the yield of Winter Maize (Zea mays L.). The experiment was laid out in randomized block with 13 treatments, each replicated three times, using Maize variety Arjun. The experimental observations were recorded during the cropping time are Length of the cob, weight of the cob, grain yield, pH, Ec, organic carbon, available nitrogen, available phosphorus and available potassium. 25 per cent nitrogen through poultry manure plus 75 percent nitrogen through urea (T8) found to be best in case of growth parameters.pH of the soil marginally decreased from intial values of soil by the use of different organic nutrient sources and electrical conductivity was found to be highest in 25 per cent poultry manure plus 75percent nitrogen (T8). Application of 25 per cent poultry manure plus 75 per cent Nitrogen (T8) emerged as superior over all other treatments in relation to physico-chemical properties of soil of maize (Zea mays L.)
