Seed hardening, a simple method of economic rice production in rainfed ecosystem.

摘要

Seed hardening with water (24 hours soaking), KCl or triadimefon was found to induce stress tolerance in rainfed rice by way of better root growth and consequent absorption of more nutrients and water, resulting in 23-26% higher grain yields, highernet income and benefit:cost ratio. Of the 6 cultivars tested, cv. Rasi and Tulasi performed better both in terms of grain and straw yield as well as higher net income and benefit:cost ratio.
