Quality of Yellow Bell Pepper Fruits Cultivated in Fertilized Soil with Yellow Water and Cassava Wastewater

Abstract

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.

Nutrient contents and growth of corn fertigated with human urine and cassava wastewater

“…According to Araújo et al (2017a, b), the highest growth of cowpea and production of lettuce were obtained with fertigation with human urine associated with cassava wastewater. On the other hand, Ramos et al (2017) obtained increase in the quality of bell pepper fruits under fertigation with only cassava wastewater.…”

“…The agricultural use of human urine associated with cassava wastewater has been tested in the cultivation of cowpea (Araújo et al, 2017a), lettuce (Araújo et al, 2017b) and bell pepper (Ramos et al, 2017). According to Araújo et al (2017a, b), the highest growth of cowpea and production of lettuce were obtained with fertigation with human urine associated with cassava wastewater.…”

ADUBAÇÃO DO PIMENTÃO (Capsicum annuum) COM A MANIPUEIRA E SEUS EFEITOS: UMA REVISÃO

“…O pimentão (Capsicum annuum) está entre as principais hortaliças cultivadas no Brasil, sendo um alimento com alto teor de valor nutricional, bem como, fonte de várias vitaminas, como A, C e E, característica medicinal devido ao alto teor de propriedades antioxidantes (RAMOS et al, 2017).…”

“…Logo, representa uma atividade com significativo impacto ambiental negativo pela geração e produção de resíduos inorgânicos (RAMOS et al, 2017). Isto é, além do aspecto agressivo ao ambiente, deve ser considerado também que o despejo indevido dos subprodutos da mandioca constitui em desperdício de rendimento para o produtor (LIMA e VALENTE, 2017).…”

“…Contudo, o reaproveitamento de águas residuárias como a manipueira está sendo estudado como fonte de manutenção da fertilidade do solo e redução do uso de água de qualidade superior (RAMOS et al, 2017). E, segundo Bertoncini (2014), este reaproveitamento de resíduos na agricultura tornou-se uma prática viável para trazer benefícios ambientais variados pel exploração de matéria orgânica.…”
