Cultivo de pimenteiras submetidas a níveis e qualidades de água de irrigação e fontes orgânicas de adubos.

Abstract

In irrigated agriculture reuse of water of lower quality is an alternative to regions with water shortages, because the cost of inputs like fertilizers during cultivation.Thus, this research has been developed in order to evaluate the effects of irrigation with waters of different qualities and replacement levels in the cultivation of peppers under Organic fertilization, with experiment under protected environment the CTRN/UFCG and in field on the campus of UEPB Lagoa Seca. In experiment 1 the experimental design was randomized blocks, in factorial scheme 2x5x2, and 2 types of water (water supply and wastewater treated), 5 water levels based on need hydro (NH), culture (100%, 80%, 60%, 40% and 20%) and 2 types of organic substrates (cattle and sheep), in 3 repetitions, with 2 plants per plot using the pepper BRS Moema, were evaluated development variables and physico-chemical properties of organic substrates in the end of cultivation. In experiment 2 randomized in blocks at random, in factorial scheme 3 x 6 + 1 (witness supply water without addition of cattle manure with 100% level of NH), being 3 blades of irrigation with wastewater [100%, 75% and 50%] and 6 ounces of cattle manure [0%, 10%, 20%, 30%, 40% and 50%], cultivating the malagueta pepper, were evaluated variables of production and quality of peppers produced. From the data obtained from the substrate in beef peppers germination of Beak had better averages, expressed through 44% germination and the irrigation level that released water demand of culture provided was 80% and 100% with the need of water peppers Pout. The peppers peppers irrigated with 75 and 50% of the water needs of culture produced peppers with best features in the physical qualities of the fruit and the substrate composed of 50% cow manure allowed best medium production of chili peppers.
