  To optimize the NPK fertilizers requirements with hybrid rice (CORH 2) and graded levels of NPK during (Pishanam) wet season (September 2000 to January 2001), a field experiment was conducted in Alfisols of Agricultural College and Research Institute, Killikulam, Tamil Nadu. The experiment was laid out with 14 treatments of NPK combinations. The results indicated that among the treatments, application of 150:75:50 kg N: P2O5: K2O ha-1 had registered the higher grain yield of hybrid rice. The 150:50:50 kg N, P2O5 and K2O ha-1 fertilizer treatment had the higher total Phosphorus and K uptake. The N, P2O5 and K2O doses, respectively 200: 75:75; 200:10:100 and 200:50:75 kg ha-1 resulted in higher soil available N, P and K, irrespectively in post harvest soils after the CORH2 rice hybrid. The physical optimum levels for getting the maximum grain yield for the medium duration rice hybrid CORH2 was found to be 151:66:57 kg N, P2O5 and K2O ha-1. The economic optima for N, P2O5 and K2O are 149:62:56 kg ha-1, respectively for obtaining the highest grain yield.

  A field experiment was conducted in the saline field of Annamalai University, experimental farm, Annamalai Nagar during Kharif season of 2000-2001, to study the screening of rice accessions for growth and yield attributes contributing to salinity tolerance. The experiment was laid out in Randomized Block Design with three replications. Fifteen rice accessions from the International Rice Soil Stress Tolerance Screening Nursery Trial (IRSSTN) of IRRI were used for the study. Based on the grouping, the rice accessions were grouped into High Yielding Tolerant (HYT), High Yielding Susceptible (HYS), Low Yielding Tolerant (LYT) and Low Yielding Susceptible (LYS). The results revealed that the rice accessions of the high yielding and tolerant group recorded a higher value for the yield characters viz., number of productive tillers/hill, number of filled grains/panicle and thousand grain weight in which Rice Acc. No. 12 (IR-60494-2B-18-3-2-3) recorded the highest value for yield characters. The rice accession of the high yielding and tolerant group recorded a higher value for the grain and straw yield of which Rice Acc. No. 12 (IR-60494-2B-18-3-2-3) recorded the highest value for grain and straw yield. Based on the results of the investigations, it clearly indicates the direct effects of growth and yield attributes on the higher yield of rice accessions for salinity tolerance. It appears that the number of productive tillers/hill, number of filled grains/panicle and thousand grain weight had direct influence on the grain yield of rice accessions grouped in high yielding and tolerant category for saline soils.
