| dc.description.abstract | A field experiment entitled “Effect of different combinations of organic nutrient sources on growth and yield of maize (zea mays L.) under cauvery command area” was conducted at Zonal Agriculture Research Station, V.C. Farm Mandya, during kharif season of 2009-10 on sandy loamy soil to study the effect of different combinations of organic nutrient sources on growth and yield of maize, soil properties, uptake of NPK in maize and to compute B: C ratio. The treatment consists of FYM, poultry manure, vermicompost, press mud equivalent to FYM (N) in combination of biodigester liquid and cattle urine equivalent to 150 kg N compared with recommended dose of FYM+NPK. The experiment was laid out in a randomized complete block design with nine treatments replicated thrice. significantly higher plant height (187.17cm), number of leaves per plant (13.32), grain yield (61.84 q ha-1) and stover yield (111.31 q ha-1) was recorded in the treatment combinations of recommended dose of FYM 10 t ha-1 + NPK 150: 75: 40 kg ha-1 N and it was on par with the treatment combinations of poultry manure equivalent to FYM (N) + biodigester liquid equivalent to 150 kg N. The soil properties viz., Bulk density , particle density, maximum water holding capacity, pH, EC, OC, major nutrients, secondary nutrients and micronutrients (Zn,Fe,Mn &Cu) was not differed significantly due to different combinations of organic nutrient sources. Significantly higher total nutrient uptake of N, P and K (194.17, 50.70 and 223.60 kg ha-1 respectively) were recorded in the treatment receiving FYM 10 t ha-1 + NPK 150: 75: 40 kg ha-1 N. Higher B: C ratio (3.15) was recorded in the treatment combination of poultry manure equivalent to FYM (N) + biodigester liquid equivalent to 150 kg N followed by the treatment combinations of FYM 10 t ha-1, recommended NPK 150: 75: 40 kg ha-1 N (3.08). | en_US |
