Effect of Moisture Stress on Dry Matter Production, Dry Matter Partitioning and yield in Groundnut (Arachis hypogea L.) Genotypes

Background: Drought is a leading abiotic factor limiting groundnut production globally. Therefore, the screening and development of moisture stress tolerant genotypes key issue towards sustainable agriculture. Methods: An experiment was laid in split plot design taking two conditions, control (T1) (T2) as main treatments 7 sub treatments. Several morpho-physiological traits like dry matter production, partitioning, photosynthetic traits, relative water content, were measured after 10 days imposition. Yield yield attributes also recorded at harvest along with drought tolerance index principal component analysis. Result: Results showed significant differences among conditions. Significant decrease observed chlorophyll total partitioning efficiency, except specific leaf area all genotypes. TCGS-1694 have been identified stress-tolerant analysis higher efficiency interms rate, to pods, index, while Kadiri-6 has susceptible genotype.
