Abstract:
The present study on the topic “Assessment of physiological indices for growth and yield of groundnut (Arachis hypogaea L.) was performed at AICRP on groundnut, M.P.K.V., Rahuri, (M.S.) during summer 2021.The experiment was laid out in Randomized Block Design with three replications includes sixteen genotypes. The observations on growth and morphological characters, dry matter accumulation and its distribution, phonological traits, physiological parameters, biochemical analysis i.e. protein, oil, chlorophyll content and correlation studies were recorded. The yield and yield attributes were recorded at harvest. The increased growth was higher between 60 DAS to 80 DAS. The groundnut genotypes with highest rate of photosynthesis and transpiration processes are higher in yielding. According to correlation studies, it was concluded that primary and secondary branches, number of mature pods per plant, 100 kernels weight (g), TDM (g) per plant, leaf area (dm²) per plant showed maximum influence on dry pod yield (g/plant). The genotypes Phule Unnati, ICGV-15311 and ICGV-15303 showed higher yielding ability this may be due to the most promising yield contributing characters like number of mature pods per plant, hundred kernels weight (g), dry pod yield per plant and HI (%).
