Abstract

Growth characteristic of crop plants ultimately decides the crop productivity. In low land rice production growth attributes can be enhanced through integrated nutrient management (INM) and effective cultivation practices. In this view to enhance the crop productivity by influencing better growth of rice plants in low lands, an experiment was conducted at experimental farm, Faculty of Agriculture, Annamalai University, Tamil Nadu, India. Experiment was laid out in split plot design with two main plot treatments (SRI and conventional system of cultivation) and seven sub plots treatments (integrated nutrient management practices) and replicated thrice. Growth attributes viz., plant height, number of tillers, DMP, root length, root volume and root dry weight hill-1 values were recorded at tillering, flowering stages and at harvest. Enhanced growth attributes were noticed under system of rice intensification method of rice cultivation i.e. more than 35 percent increases over conventional system of rice cultivation. Among the integrated nutrient management practices, the application of STCR based IPNS (combined application of NPK fertilizer along with 12.5 t ha-1 FYM and bio-fertilizers viz., Azospirillum and PSB as soil treatment) proved its superiority over other treatments significantly. It was closely followed by application of 75% fertilizer N + 25% organic N through EFYM. Lower values of growth attributes were registered by 100% RDF applied treatment at all the crop growth stages. From the experimental results, it may be concluded that STCR based IPNS or 75 percent N through inorganic and 25 percent N through EFYM or FYM could be the better options for enhancing growth attributes of low land rice crop for improving its sustainable productivity.
