Abstract

Phosphorus gets fixed (.> 80%) and becomes unavailable to crop after its application to soil. Baby corn can be successfully followed after groundnut. The experimental was conducted at RRS, BCKV, Jhargram during 2019 and 2020 in split plot design with three main and six subplot treatments to find out the effect of phosphorus management on growth and yield of groundnut varieties and its residual effect on succeeding baby corn. Highest pod yield (2007 kg/ha), shelling % (67.35%), Oil % (49.97%), number of nuts/plant (23.23) & 100 kernel weight (40.55g) were obtained with groundnut variety TG 51 and application of (100% RDP + PSB + FYM). The residual effect was highest for variety TAG 24 and above said phosphorus dose applied to previous groundnut. So, groundnut variety either TG 51 alone or TAG 24 followed by baby corn can be successfully grown with application of 100% RDP + PSB + FYM.

Conclusion

So, groundnut variety either TG 51 alone or TAG 24 followed by baby corn can be successfully grown with application of phosphorus @ 60 kg/ha along with PSB @ 25 g per kg of seed & FYM @ 2 ton /ha. Regarding the beneficial role of PSB & FYM, FYM performed little better than PSB on different growth (particularly at later crop growth stage) & yield parameters of groundnut crop and for the subsequent baby corn PSB was found better than FYM. Inoculation of PSB and FYM to reduced phosphorus dose (75% of RDP) may be recommendable to farmers instead of 100% RDP application for prolonged residual effect on succeeding crops.
