PARÂMETROS DE CRESCIMENTO E PRODUTIVIDADE DE VARIEDADES DE FEIJÃO CAUPI CULTIVADAS SOB PROCESSOS AGROECOLÓGICOS EM CONDIÇÕES DO SEMIÁRIDO

Abstract

Community Seed banks (CSB) are important organizations in the management of biodiversity and food safety, despite the advance in the organization of these CSB, they still have some limitations determined by technological factors. By receiving a significant number of criola varieties (traditional), who is in charge for the CSB does not always know the genetic potential of each material, and its adaptations for its various production environments, especially the conditions of soil fertility. This study aimed to compare the grain production and growth parameters of traditional varieties of Caupi beans with commercial varieties, based on agro-ecological processes semi-arid region of Paraíba. The experiment was installed in a factorial scheme 4 blocks x 4 treatments (T1-witness; T2-10 t ha-1 of organic compost, being, manure, + vegetable materials; T3- 4.2 t ha-1 of dust rock ; and T4 - 5 t ha-1 of dust rock + 2.1 t ha-1 of organic compound) x 3 varieties, being, and commercial identified as 1-Nova Era and 2- Guaribas (provided by EMBRAPA), and 01 traditional, 3- Sedinha (already in common use by farmers). The field project was developed in partnership with Assessoria e Serviços em Agricultura Alternativa (AS-PTA), which was also used as experimental unit, located in Esperança – PB, the soil of the experimental area was a Regolitic Neosoil, the evaluation parameters were: number of plants (NP), plant height (PH), number of leaves (NF), leaf area (LA) , stem diameter (SD) number of pods per plant (NPP) total weight of seeds (TWS), grain productivity (GP) and dry matter production of aerial part (PMSPA), the analyses were performed at the Laboratório de Matéria Orgânica, situated at DSER/CCA/UFPB. . On the average productivity of each variety, depending on the treatment, it was observed that the grain production of the variety 3-Sedinha, showed the greatest result in relation to the other, getting the weight of 228.406 kg/ ha -1, this variety also stood out among the others, when compared against the parameters of growth and development of the culture. Among the treatments, the one that expressed the best behavior in production, independent of the varieties studied, was the organic compound.
