Stimulated effect of organic and inorganically originated transitory nitrogen sources on the nutrient concentration, uptake and production of hybrid maize

Abstract

Soil productivity one of the essential factors which enhanced either through adding the chemical fertilizer or by incorporation of organic sources of nutrients to the soil. Regardless by the used of imbalanced fertilizer without the application of organic manure and without seeking knowledge of crops and fertility classification of soil causes to much hazards such as deterioration of soil structure, soil and water pollution etc. Two years field experiment was carried out to check the impact of transitory nitrogen sources on the nutrient concentration, uptake and production of hybrid maize at the Agronomic Research Area, University of Agriculture Faisalabad, Pakistan, during the year 2008-2009. Treatments included two hybrids: H1 (Pioneer-30Y87) and H2 (Pioneer-31R88) with six nitrogen sources each, which included at the rate of S0: control (0) kg N ha-1, S1: chemical source (urea) 250 kg N ha-1, S2: poultry manure (PM) 9.6 t ha-1, S3: farm yard manure (FYM) 17.8 t ha-1, S4: pressmud of sugarcane (PMS) 8.5 t ha-1 and S5: compost (C) 10.0 t ha-1. Finding concluded that changing effect of nitrogen sources on both maize hybrid was found to be non significant during 2008-2009 while grain yield was significant during both years. Maximum nutrient concentration, uptake and yield were observed with nitrogen source S1: chemical source (urea) 250 kg N ha-1 during 2008-2009 as compared to other nitrogen sources and minimum was found in control (0) kg N ha-1, respectively. Interaction among hybrid and nitrogen sources was found to be non significant.
