Agromic behavior of pigeonpea cultivars (Cajanus cajan L.) Millsp.
Main Article Content
Abstract
Find alternatives to food production and are in turn crops food and nutritional value is a necessity of the present moments. The INIFAT has collections of species with high value, among which is the gandul which is a legume with high nutritional value and multiple uses as may be used for human and animal feed. The work had as main objective evaluate the agronomic performance of cultivars of gandul beans to propose more competitive range. It is a culture that tolerates high stress conditions aspect that gives value to studies of adaptability to tropical conditions. For the study were used six cultivars belonging to the collection of gandul beans (Cajanus cajan L.) of the INIFAT in red Ferrallitic soil, which were characterized and evaluated attending international descriptors listings. All cultivars collected nodules in the roots from which a total of 25, of which only 10 corresponded with the genus Rhizobium isolates. By a selection for their ability to fix nitrogen in conditions in vitro, only three showed a positive response, which correspond to the collected cultivate ´Cándido´ which, in turn, showed the greatest potential for its high grain yield, small carving in its architecture and 148 days harvest cycle.
