Abstract
<!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } --> The objective of this study was to evaluate the effect of doses and sources of nitrogen and phosphorus, on the production components and grain yield, on irrigated common beans cultivated in a Cerrado area of Selvíria, Mato Grosso do Sul State, Brazil (20°22���S, 51°22’W, altitude 335 m). The experimental design was a randomized block, with 4 doses of top-dressed N (0 kg ha-1, 40 kg ha-1, 80 kg ha-1, and 120 kg ha-1) and 2 sources (urea and coated urea), and 4 doses of phosphorus (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, and 150 kg ha-1 of P2O5) and 2 sources (triple super phosphate and coated triple super phosphate), at sowing, with 4 repetitions. Nitrogen and phosphorus content in leaves, pod/plant number, grain/plant number, mass of 100 grains, and grain yield were evaluated. The sources of N, as well as the sources of P2O5, did not differ, as related to the number of pods per plant, grains per plant, mass of 100 grains, and grain yield. The doses of N influenced linearly the leaf N content, as well as the grain yield. The doses of P increased linearly the leaf P content and the grain yield, up to the 120 kg ha-1 dose. KEY-WORDS: Phaseolus vulgaris L.; coated fertilizer; Cerrado. <!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } --> O objetivo deste trabalho foi avaliar o efeito de doses e fontes de nitrogênio e fósforo, sobre os componentes de produção, e a produtividade do feijoeiro irrigado, cultivado no inverno, na região de Selvíria, MS (20°22’S, 51°22’W e altitude de 335 metros). O delineamento experimental adotado foi o de blocos casualizados, com 4 doses de N em cobertura (0 kg ha-1, 40 kg ha-1, 80 kg ha-1 e 120 kg ha-1) e 2 fontes (uréia e uréia revestida). Para o fósforo, foram 4 doses na semeadura (0 kg ha-1, 50 kg ha-1, 100 kg ha-1 e 150 kg ha-1 de P2O5) e 2 fontes (super fosfato triplo e super fosfato triplo revestido), com 4 repetições. Foram avaliados os teores de nitrogênio e fósforo foliar, número de vagens e grãos planta-1, número de grãos vagem-1, massa de 100 grãos e produtividade de grãos. As fontes de N, bem como as fontes de P2O5, não diferiram entre si, quanto ao número de vagens por planta, grãos por planta, massa de 100 grãos e produtividade de grãos. As doses de N influenciaram, linearmente, tanto o teor de N foliar, como a produtividade de grãos. As doses de P2O5 aumentaram, linearmente, o teor foliar de P e a produtividade de grãos, até a dose de 120 kg ha-1. PALAVRAS-CHAVE: Phaseolus vulgaris L.; fertilizantes revestidos; Cerrado.
