Abstract

There is a dire need to explore the potential of seed priming in different aged rice nursery seedlings under system of rice intensification. The field experiment was executed to evaluate the role of seed priming in improving the performance of nursery seedlings for system of rice intensification during the 2 nd week of June, 2010 and 2011 at Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan. The experiment was laid out into randomized complete block design with split split plot arrangement having three replications. The experimental treat ments were comprised of two rice varieties (Super Basmat i and Shaheen Basmati), three seedling ages (2, 3 and 4 weeks old) and seed priming (non-primed seeds; control and primed with 1.5% solution of CaCl 2). The results showed that rice cult ivars, seedling age and seed priming significantly improved the leaf area index, crop growth rate, leaf area duration and net assimilation rate during both the years. Two weeks old seedlings performed better than 3 and 4 weeks old seedling by improving t iller production, kernels per panicle, 1000 grain weight, kernel yield, straw yield and harves t index. Two weeks old seedlings raised from seeds osmoprimed with CaCl2 improved kernel quality and remained best by giving higher net benefits (Rs. 136124 & 144933) and marginal rate of return (35 & 39) during the year 2010 and 2011.
