Abstract
The study was conducted to determine the optimal fertilizer levels for Kadiri Lepakshi groundnut. The experiment consists of eight treatments and was laid out in randomized complete block design with three replications. The present investigation was conducted at Integrated Farming System demonstration plot, ZARS, UAS, GKVK, Bengaluru Karnataka, during the summer of 2022 and Kharif 2023. Five plants from the sampling area were randomly selected and observations on growth and yield parameters were recorded at 30, 60 and 90 days after sowing (DAS) and at harvest. The results revealed that among the various nutrient levels, application of 100 % RDF combined with Phosphogypsum @ 750 kg ha-1 and Borax @ 10 kg ha-1 resulted in significantly higher values for plant height (32.95 cm), number of branches per plant (12.60) and dry matter production at harvest. This treatment also led to a substantial increase in the total number of pods per plant (59) and filled pods per plant (48) in groundnut, performing on par with the treatment that included 100% RDF, Gypsum @ 750 kg ha-1 and Borax @ 10 kg ha-1 (with 57 and 44 pods, respectively) when compared to other treatments. The similar trend was observed with respect to pod yield (2327 kg ha-1), kernel yield (1580 kg ha-1), and haulm yield (3594 kg ha-1). So, the application of 100% RDF with Phosphogypsum @ 750 kg ha-1 and Borax @ 10 kg ha-1 significantly enhanced growth attributes (plant height, branches per plant, and dry matter production) and yield parameters (pods per plant, filled pods, pod yield, kernel yield, and haulm yield) in groundnut. This indicates that Phosphogypsum is an effective source of calcium and sulfur for boosting groundnut yield.
