Abstract:
A field experimental trail on groundnut was conducted during Kharif, 2021 at Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (U.P.) to evaluate the effect of biofertilizers and gypsum levels on growth and yield and of groundnut. The soil of the experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225 kg/ha), available P (19.50 kg/ha), available K (92 kg/ha). The experiment was laid out in Randomized Block Design (RBD) with ten treatments replicated thrice. In the view of this experiment, two kinds of biofertilizers were used for seed treatment and three levels of gypsum (200, 300 and 400 kg/ha) along with RDF and control plot with RDF alone. Results revealed that significantly higher growth parameters at 60 DAS and yield parameters at harvest viz: plant height (44.47 cm), plant dry weight (14.80 g), number of pods per plant (25.00), number of kernels per pod (2), seed index (40.33 g), shelling percentage (74.00%), pod yield (3.64 t/ha), seed yield (2.69 t/ha), haulm yield (4.45 t/ha) and harvest index (33.29%) were recorded with the application of Bradyrhizobium 2g/kg seed + Trichoderma harzianum 2g/kg seed + 400 kg/ha Gypsum. Thus, with the use of Bradyrhizobium 2g/kg seed + Trichoderma harzianum 2g/kg seed + 400 kg/ha Gypsum per hectare along with RDF could be a promising option for yield enhancement in groundnut.
