Studies on Drought Tolerant and High Yielding Groundnut Varieties in Perambalur District

Three varieties of groundnut were used to assess the drought tolerance and high yielding potential. Groundnut (Arachis hypogaea L.) is an important oil seed crop mainly grown under rainfed situation. Erratic rainfall frequent during growth period, yields are generally low conditions. Drought critical stages crucial for loss in yield varieties. But tolerant genotypes may give better due maintenance physiological responses that triggered drought. On Farm Trials was conducted by Krishi Vigyan Kendra, Hansroever campus, Perambalur district Tamilnadu, India suitable variety terms yield, acceptability adoption potential rabi 2018-19 district, India. viz., Dharani, Co7 TMV 7. The study revealed Dharani recorded higher pod (2402 kg ha-1), number pods plant-1 (26) optimum plant population (26.3 plants m-2) as compared farmers practice. resulted highest shelling percentage (75%), while lowest registered with Gross net returns ` 115324 66593 ha-1, respectively cultivating against 87523 41550 ha-1 check variety. would be a option forrainfed cultivation district.
