Abstract

Studies were initiated to evaluate the influence of seed priming technique (Tricoderma viride 10%, Tricoderma viride 10% + Rhizobium 10%, Tricoderma viride 10% + Rhizobium 10% + Phosphobacteria 10%, Carbendazim + Rhizobium 10% + Phosphobacteria 10%and control) in conjunction with crop management techniques viz., foliar spray (Panchakavya 1 %, Ground nut rich 1% and Panchakavya 1 % + Ground nut rich 1%) along with NPK application. The results revealed that seeds primed with Tricoderma viride 10% + Rhizobium 10%+ Phosphobacteria 10%,and foliar sprayed with 1 %ground nut richas crop management technique improved the productivity of ground nut and the seed recovery. On comparison of seed and crop management techniques the contribution of seed management technique was higher than crop management techniques.

Conclusion

The seeds primed with combinations of bio products evaluated for seed quality characters were (Tricoderma viride 10%, Tricoderma viride 10% + Rhizobium 10%, Tricoderma viride 10% + Rhizobium 10% + Phosphobacteria 10%, carbendazim + Rhizobium 10% + Phosphobacteria 10%) evaluated for productivity along with unprimmed seeds under ambient conditions of coimbatore, where the primed seeds were dried back to original moisture content. The results indicated that Tricoderma viride 10% + Rhizobium 10% + Phosphobacteria 10% performed best compared to unprimed seeds at productivity, measuring the higher order level of morphological, yield and yield attributing characters in terms of field emergence, plant height @ 60 DAS, No. of branch per plant, number of pods per plant, pod weight per plant, number of seeds per plant, seed yield per plant, seed yield per hectare. The seeds foliar spray of organic products evaluated for yield characters were (foliar application of Panchakavya 1%, foliar application of groundnut rich 1%, foliar application of Panchakavya1%+groundnut rich1%) evaluated for productivity. The results indicated that foliar application of groundnut rich 1% performed best compared to foliar application of Panchakavya 1% at yield and yield attributing characters.
