Growth of Groundnut (Arachis hypogaea L.) as Influenced by Genotypes and Sulphur Levels

Groundnut is an important oilseed crop and belongs to the family Leguminosae. However, the productivity of groundnut in India is less as compared to average productivity of the world. The type of variety and nutrient, especially sulphur is crucial for the physiological growth and yield of crops like groundnut. Because groundnut is a legume-oilseed crop, it has a high phosphorus, calcium and sulphur demand. Therefore, this field experiment was conducted during the Kharif season of 2023 at crop physiology field lab, Department of Agronomy, CCS Haryana Agricultural University, Hisar. The experiment was laid out in split plot design with four genotypes (G1-MH 4, G2-HNG 10, G3-HNG 69, G4- GNH 804) in main plots and four sulphur levels (S1-Control, S2-20 kg S/ha, S3-40 kg S/ha, S4-60 kg S/ha) in sub-plots with three replications. Among the groundnut genotypes, GNH 804 found best in respect to the studied growth parameters followed by HNG 69. Among the sulphur levels, application of 60 kg S/ha recorded significantly higher variation for most of the studied parameters closely followed by sulphur levels of 40 kg/ha.
