Impact of integrated nutrient management on performance of rice under system of rice intensification (SRI)
Author(s): L. Tzudir and R.K. Ghosh
Abstract: Field experiment was conducted during season 2008-09 on up-medium land situation at ‘C’ Block (Incheck) Farm, Kalyani, BCKV to study the effect of combination of organic manures and inorganic fertilizers on rice production using SRI technology. The experimental results revealed that the best result was obtained with application of 75% N (Enrich Adhar) + 25% N (Urea) + PK and consequently an increase in grain yield by 27.63%, 28.98% and 20.94% was observed over full NPK (60:30:30), 75% N (urea) + PK and farmers’ practice treated plots respectively. The corresponding increases in straw yields were 23.38 24.4 and 17.73% respectively. Organic sources of plant nutrient also showed positive effect on other yield attributes such as panicle length, tiller number and filled grains per panicle. The effect of different treatments on availability of soil nutrients also showed that application of integrated plant nutrients showed better results and application of 75% N (Enrich Adhar) + 25% N (urea) + PK resulted in highest nitrogen percentage, available phosphorus and potassium respectively, while the lowest was from sole application of NPK through inorganic nutrient sources...
