Navneet Tripathi and Jeetendra Kumar Rao
Chickpeas contain protein, carbohydrates, and the right amount of fat, making them highly nutritious. They are also rich source of calcium, iron, vitamin C (green plants), and vitamin B. It is used in various forms such as dal, chhole, sweets, flour, and other attractive dishes. Their leaves contain malic acid and citric acid, which are very helpful for stomach ailments and are the best blood purifier. The fungi causes several diseases in chickpea among them Fusarium wilt is common. Fusarium oxysporum f. sp. ciceri. was isolated from root of wilted plants of chickpea and extract of ten plant species were tested against wilt causing pathogen Fusarium oxysporum f. sp. ciceri. Among them Hyptis suaveolens was found most active against wilt pathogen. In the present investigation plant extract of Hyptis suaveolens has been selected for phytotoxicity against chickpea. The extract of Hyptis suaveolens had no adverse effect on the root - shoot lengths of the host plant because the root/shoot length ratios for treatment set was approximately equal to that of control set. When the seeds were treated with the extract of Hyptis suaveolens for 4h showed better results than 2h as 36 plants were found to be healthy on 50 days in 4h treatment while 27 plants were healthy in 2h treatment and all the plants were found to be completely wilted on 31 day in control set.
