PRODUÇÃO E APROVEITAMENTO DE RESTOS CULTURAIS DE ABACAXI IRRIGADO NO CERRADO GOIANO

Abstract

The objective of this work was to evaluate the vegetative, productive and nutritional value of the silage of the cultural remains of Pérola pineapple under different drip irrigation blades during the flowering period. The work was conducted at the Goian Federal Institute - Campus Ceres - GO, following the randomized blocks design with five treatments of average evapotranspiration of the Class “A” tank: 0, 35, 55, 75 and 105%, with four replications to evaluate development, production and productivity characteristics and a completely randomized design and to three treatments of fermentation times of pineapple silage, with 0, 30 and 90 days of fermentation, with five replications. The analyzed variables were: peduncle height. leaf length 'D'; number of seedlings; plant height; number of leaves; length of the fruit with and without crown; circumference of the fruit; weight of the fruit with and without crown; productivity; soluble solids content; fresh pasta; dry mass, protein, silage pH, FDN and FDA. There was no significant difference for peduncle height, leaf length 'D', number of seedlings, fruit length with and without crown, soluble solids concentration and productivity. The variables plant height, total leaf number and fresh matter weight presented a linear behavior in relation to the water slide. The circumference of the fruit is greater in the lamina relative to 66.87% of the ECA. It is advisable to wait for 60 days of fermentation of the silage, so that the protein and pH content reach the recommended limits.
