摘要

Mid-storage seed invigoration treatments in medium vigour rice seeds effectively controlled seed deterioration of rice after subsequent ageing. Dry dressing treatment with aspirin (ortho-acetyl salicylic acid) @ 100 mg/ kg of seed, crude plant material, viz., neem leaf powder @ 2g/ kg of seed and wet treatment (soaking in double volume of water for 4 h at room temperature and then drying back to its original moisture content) showed significant improvement on field performance and productivity over untreated control in both System of Rice Intensification and conventional method. Among the treatments, dry treatments have shown better results in improving field performance and productivity. The increase in yield was significantly higher in SRI method than the conventional one. Among the dry and wet treatments, aspirin in particular showed better results in improving storability, yield and other yield attributes. The interaction between treatment effect and cultivation methodology was not significant implying thereby that the treatment effect was independent of cultivation method. The membrane functions as measured by electrical conductance of seed leachate and leakage of sugar were significantly lower in the wet and dry treated seeds than the untreated control. The dehydrogenase activity was significantly higher in the treated seeds than the untreated control. On the basis of the present result, mid-storage dry treatment with aspirin and neem leaf powder employing System of Rice Intensification has been suggested to the rice growers for improved storability, field performance and productivity.
