Evaluation of single pod sowing in groundnut

Abstract

In groundnut, the coverage of area by a particular variety is very poor compared to cereals, this is mainly due to non-availability of quality seeds at the time of sowing. The formation of single pods is inevitable one. To utilize the single pods as such without decorticating, it can reduce shelling cost and meet out the demand of the crop at needy time. The present investigation has been formulated and conducted at Oilseeds Research Station, Tamil Nadu Agricultural University, Tindivanam during January 2018 with the six different soaking treatments viz., soaking of single pods for 5 hrs, 10 hrs, 15 hrs, 20 hrs, sowing of dry pods as such and kernel sowing as control in two varieties TMV 13 and VRI 7. From the above treatments irrespective of varieties, the results of 20 hrs soaked seeds is on par with kernel sowing in number of days to emergence (5 days), days to initial (26 days)and 50% flowering (33.5 days) flowering and in all yield parameters including No. of pegs/plant (32.7 for kernel sowing and 31.8 for 20 hrs soaked pods), No. of pods/ plant (27.3 for kernel sowing and 26.7 for 20 hrs soaked pods), 100 seed weight (45.3 for kernel sowing and 45.0 for 20 hrs soaked pods) and seed yield/ha (1904 for kernel sowing and 1858 for 20 hrs soaked pods).
