Uso de rejeito da indústria leiteira na produção de amendoim consorciado com palma forrageira

Abstract

The cactus pear is a culture of long cycle, which require the producer to find alternative source of income and can be a viable practice the consortium. The present study aimed to determine the appropriate dose of dairy waste to meet the nutritional needs of the peanut variety BR1 and determine the best population in peanut intercropped with forage cactus. The experiment was conducted under field conditions in the municipality of Garanhuns. In two stages, where the first was to determine the best dose of the milk residue able to meet the nutritional needs of peanuts. And a treatment fertilization (PK chemistry with) the doses of milk residue (0.0; 2.5; 5.0; 7.5 and 10.0 m3 ha-1) treatments were used. The experimental design was a randomized block design with three replications and six treatments, five doses of milk residue and a treatment containing P and K. The yield of groundnut was higher in the dose of 10 m3 ha-1. The second step was to determine the best population of peanut intercropped with being fertilized with the dose of milk residue determined in the previous step cactus pear. The treatments were T1 = Single Cultivation of cactus pear , T2 = Growing a single line of peanuts per plot, T3 = 2 Growing Single peanut lines per plot, T4 = 3 Growing Single peanut lines per plot, T5 = Palma 1 row intercropped with forage peanut, T6 = forage Palma intercropped with 2 rows of peanuts, T7 = forage Palma intercropped with 3 rows of peanuts. The characteristics evaluated were: shoot height, stem number, stem diameter, diameter of the main root diameter of pods, number of days for early flowering, number of gynophores not throw the soil, total biomass, number of pods, peanut production in the bark, productivity grain. In cactus pear were assessed the number of cladodes, length, width and diameter of the cladodes, plant height, yield and percentage of dry mass. The dose of 5.8 m3 ha-1 was efficient on the agronomic characteristics of peanut. The best production was obtained for the cultivated peanut with 225,000.00 plants per acre. The intercropping system does not impair the initial development of cactus in early do. The efficient use of land was efficient regardless of intercropping population.
