INFLUENCE ON SEED DESIGNING ON THE PRODUCTIVITY AND THE RESULTANT SEED QUALITY OF RICE CV. ADT 39
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 57
Abstract
To evaluate the influence of seed designed with different seed management techniques in rice, the seeds of rice cv. ADT 39 were imposed with physiological (seed hardening with KCl one per cent for 16h and drying back to original moisture content), physical (seed coating with polymer @ 3 ml that followed with sequential application of imidacloprid @ 2 ml, P. fluorescens @ 10 g and Azophos @ 120 g kg -1 of seed) and their combinational seed treatment (designer seed) (seed hardening with KCl one per cent for 16h and drying back to original moisture and combined with seed coating treatments viz., polymer @ 3 ml + imidacloprid @ 2 ml, P. fluorescens @ 10 g and Azophos @ 120 g kg-1 of seed) and were evaluated for their production potential in comparison with untreated seed. The results revealed that the field emergence was four per cent higher with designer seed than untreated seed and hardened seed. The yield attributing characters measured through number of panicles plant-1, panicle yield plant-1, seed yield plant-1 and the seed yield ha-1 were higher with designer seed which exerted a percentage increase of 4.0, 29.1, 61.1 and 22.5 per cent in comparison with untreated seed on seed yield. The resultant seed quality characters observed germination, shoot length and vigour index were also higher than untreated seed by 3.2, 0.71 and 9.1 per cent.
