Nitrogen management strategies on growth

Farmers in flood prone areas mostly use only urea without any solid recommendations. Possibilities of recurrent flooding/submergence during the season are one of reasons for avoiding nutrient application, through it has a strong bearing on regeneration growth and yield of rice varieties after floods, hence suitable nutrient management strategies are essential to enhance the productivity.

A field experiment was conducted to investigate the methods of cultivation and optimization of nitrogen requirement of rice crop in coastal alluvial soils, Karaikal, Pondicherry, India. Experiment was laid out in a split plot design with methods of rice cultivation as main plot treatment consisted of System of Rice Intensification (SRI), Integrated Crop Management (ICM), Line Planting (LP) and Random Planting (RP) and nitrogen managements strategies as subplot treatment consisted of without nitrogen as control, blanket recommendation, LCC 4, LCC 5, SPAD 35 and SPAD 37.

Nitrogen management strategies developed so far are mainly based on soil tests targeted yield and generally N recommendations are made for large areas which certainly do not take into account the field to field and season to season variability. Nitrogen being the most dynamic nutrient, we have to develop real time N management strategies which are meant by applying the N doses to the crop as and when needed.
