Crescimento e índice de clorofila do milheto ADR 300 em monocultivo e consorciado sob adubações orgânica e mineral

Abstract

The consortium consists of growing different plant species at the same time in one area. Millet (Pennisetum glaucum), gliricidia (Gliricidia sepium) and cactus (Opuntia stricta) are rustic, productive, adapted to the Northeast and recommended for intercropping, being sources of fiber, protein and energy, respectively. The objective is to evaluate the height, tiller population density (DPP) and total chlorophyll of millet in monoculture and intercropped with cactus and/or gliricidia with organic and mineral fertilization in the Brazilian semi-arid region. The experiment was conducted at the Federal Institute of Education, Science and Technology of Piauí - IFPI, Campus Valença do Piauí. The management of organic fertilization was with cattle manure and poultry manure (chicken litter). Mineral fertilization carried out simple superphosphate, nitrogen potassium chloride. A 5% Tukey test was used to compare means and the design was in randomized blocks with four treatments and 4 replications. The following fertilizer management (organic, mineral and organic + mineral) and crops (millet monoculture (MM), millet + gliricidia (M+G), millet + palm (M+P) and millet + palm + gliricidia) were evaluated (M+P+G). Total chlorophyll, millet height (cm) and tiller population density were analyzed 70 days after planting. The growth characteristics of ADR 300 millet, such as total chlorophyll and height. and tiller density are enhanced with organic and mineral fertilizers combined in intercropping with forage cactus and gliricidia, highlighting the higher density of millet tillers in monoculture and in intercropping with gliricidia.
