Abstract : A field experiment was conducted at Sardarkrishinagar Dantiwada Agricultural University
Sardarkrushinagar to study the effect of integrated nutrient management on growth and yield attributes of summer groundnut
in 2012. The soil of experimental field was loamy sand in texture, low in organic carbon (0.17 %) and available nitrogen
(149 kg ha-1), medium in available P2O5 (29.3 kg ha-1) and rich in K2O (287 kg ha-1) status.
Result revealed that the significantly highest pod yield (2650 kg ha-1), haulm yield (4633 kg ha-1), growth and yield
parameters viz., plant height (43.9 cm), filled pods plant-1(22.6), total pods plant-1(31.4), pod weight plant-1 (22.3 g)
and 100 kernel weight (43.9 g) were recorded under the treatment which received 125 % recommended dose of nitrogen through
vermicompost. While in case of phosphorus application @ 50 kg P2O5 ha-1 recorded significantly higher pod (2824 kg ha-1) and
haulm yield (4655 kg ha-1) over PSB only and 25 kg P2O5 ha-1 which was at par with the application of phosphorus @ 25 kg
ha-1 + PSB for yield attributing characters viz., filled pods plant-1, total pods plant-1, pod weight plant-1. Maximum net
realization of `1,13, 056 ha-1 with CBR 4.49 was obtained under application of 125 % RDN through vermicompost with 50 kg P2O5 ha-1 (V3P4).
Vermicompost and phosphorus did not exert its interaction effects during course of investigation. This concludes that the
groundnut crop should be inoculated with PSB culture @ 200 g per 8 kg seeds before sowing and crop should be fertilized with 125% RDN
through vermicompost and phosphorus @ 50 kg P2O5 ha-1 loamy sand soil of North Gujarat agro-climatic condition.
