Currently there is a great need for reuse of water in agricultural activity, aiming at reducing environmental impacts and production costs. The objective of this study was to evaluate the fruit production of hybrid Satrapo bell pepper, under fertilization with yellow water and cassava wastewater. The experiment was conducted in a greenhouse located at Campina Grande city, PB. The experimental design was completely randomized, with eight treatments and five replications, totaling 40 experimental plots. The treatments were characterized by fertilization with cattle manure (EB); NPK; human urine (HU); cassava wastewater (M); cassava wastewater and human urine (UH+M); the double volume of human urine (2xUH); the double volume of cassava wastewater (2xM); and the double volume of human urine and cassava wastewater (2xUH+M). At 60 day after transplanting (DAT) were evaluated the diameter, thickness of mesocarp, fresh and dry phytomass and number of lobes of yellow bell pepper fruits.According to the results, there were significant differences in the variables analyzed due to the treatments applied. The treatment corresponding to 2xM provided the highest results for length, diameter, thickness of the mesocarp, fresh and dry phytomass of the bell pepper fruits. On the contrary, 2xUH was the treatment that provided the lowest values for these variables and provided the highest number of lobes.

The objective was to map spatially and temporally the degradation of the lands of the Sucuru River basin in the region of Cariri Paraibano. The SPRING 5.2.7 program was used for the digital processing of orbital images and the photointerpretative keys for evaluation of levels of degradation, field visits, consultations with literature and public agencies. There was a regeneration of the areas that previously were in the levels of degradation very serious and moderate severe, due to factors such as the drought that is hindering the agricultural exploration, as well as the reduction of the animal exploitation and of the arboreal extractivism. The banks of the water bodies of the basin, for the most part, are at the level of severe degradation, resulting from the removal of this vegetation due to the exploitation of these areas for the most varied uses. The degradation processes, together with the incorrect use of the lands of the studied basin had as main consequence, the rural exodus, requiring the intervention of the public power so that the local communities can develop sustainable activities, considering social, economic and environmental aspects.

Nesse sentido, objetivou-se avaliar o crescimento do milho híbrido AG1051 cultivado sob fertilização química e orgânica, utilizando nitrogênio, fósforo e potássio (NPK) e combinações de manipueira e urina humana tratadas, aplicadas via solo e fertirrigação. O experimento foi realizado na Universidade Federal de Campina Grande, Campus I, Campina Grande, PB, Brasil. O delineamento experimental foi o inteiramente casualizado, com 14 tratamentos, quatro repetições, totalizando 56 unidades experimentais. Foram analisadas as variáveis altura de planta (AP), diâmetro do colmo (DC), número de folhas (NF), fitomassa fresca e seca da parte aérea (FFPA, FSPA), estado de nitrogênio na planta – índice SPAD e área foliar (AF) aos 15 dias após a emergência das plântulas. Todas as variáveis apresentaram melhores resultados em função da fertilização química com NPK, destacando-se a aplicação via fertirrigação, já a adubação orgânica promoveu valores superiores quando aplicada via solo. A variável AF apresentou aumento para todos os contrastes em relação às demais variáveis de até 147%; já a variável NF apresentou menores valores em função dos contrastes, com aumento de 2,25%.   Palavras-chave: Zea Mays L., adubação organomineral, ecossaneamento.     RAMOS, J.G.; DE LIMA, V.L.A.; PEREIRA, M.D.P.; NASCIMENTO, M.

CULTIVATION OF HYBRID MAIZE UNDER MACRONUTRIENTS, HUMAN URINE AND CASSAVA WASTEWATER APPLIED VIA BASAL DRESSING AND FERTIGATION     2 ABSTRACT   The use of organic waste in agricultural production is already a reality in several countries worldwide. In this context, this work aimed to evaluate the growth of hybrid maize (AG1051) under organic and chemical fertilization using nitrogen, phosphorus and potassium (NPK) and the combination of both treated cassava wastewater and human urine, applied through basal dressing and fertigation in a protected environment. The experiment was carried out at the Federal University of Campina Grande, Campus I, in the municipality of Campina Grande, state of Paraiba, Brazil. A completely randomized design was used, with 14 treatments and 4 replications, totaling 56 experimental units. Plant height (PH), stem diameter (SD), number of leaves (NL), shoot fresh matter (SFM), shoot dry matter (SDM), nitrogen in the plant – SPAD Index and leaf area (LA) variables were analyzed at 15 days after emergence. All variables presented better results as function of chemical fertilization with NPK, specially the application via fertigation. Organic fertilization promoted higher values when applied via basal dressing. The variable leaf area showed higher increase for all contrasts compared to the other variables (up to 147%). The variable number of leaves presented lower values due to the contrasts, with an increase of 2.25%.  Keywords: Zea Mays L., organo-mineral fertilization, ecological sanitation.

<p>The objective of this work was to evaluate the development of vetiver grass (Chrysopogon zizanioides L. Roberty) cultivated in PVC columns and fertilized with bovine manure levels under different ambient conditions. The experiment was installed in a completely randomized design, with three replications, in a factorial scheme 5 x 2 being five levels of bovine manure (0%, 10%, 20%, 30% and 40%) and two types of environments (free and protected environment with 80% opening shade), totalizing 30 experimental units. Evaluations were carried out regarding plant height and number of shoots to 15, 30, 45 and 60 days after transplanting (DAT). At 60 DAT at the end of the experiment, the plants were separated to determine the root length and the production of green and dry mass of the aerial part and the root. The results obtained showed that the absence of bovine manure contributed to the greater development of the root system of vetiver grass plants. The 10% level of bovine manure provided a greater number of sprouts and increase in the green mass of the aerial part and green dry mass of the root. The free environment provided the greatest development of vetiver grass plants.</p>
