Com o objetivo de fornecer subsidios para a recomendacao de fertilizantes para o sistema associado milho-feijao (Zea mays L.) - (Phaseolus vulgaris L.), foram conduzidos experimentos durante o ano agricola 1978/79, em duas localidades do Estado de Minas Gerais: Lavras e Patos de Minas. Utilizou-se o delineamento em blocos casualizados, segundo um esquema de parcela subdividida, com quatro repeticoes. Os tratamentos das subparcelas foram uma combinacao de tres niveis de nitrogenio (0-75-150 kg/ha) com tres niveis de P2O5 (0-150-300 kg/ha). Constatou-se para a cultura do feijao, uma interacao significativa entre o nivel de fertilizantes utilizado e o arranjo usado. No experimento de Lavras, as maiores respostas foram obtidas para P2O5 e, em Patos de Minas,... |

Finding more efficient ways to fertilize crops will reduce N losses and increase nutrient uptake. A field experiment was conducted at the Agronomic Research Farm, University of Agriculture, Faisalabad, Pakistan, during 2006 and repeated in 2007. The crop was planted in three different geometrical arrangements, viz. flat sowing (rows spaced 75 cm), ridge sowing (ridges spaced 75 cm), and strip planting (double row strips spaced 120 cm with 30 cm between rows in a strip); NPK was applied in four different combinations (0-0-0 control, 200-100-100 low dose,250-125-125 medium dose, and 300-150-150 high dose kg ha-1). Both fertilizer use efficiency (FUE) and N use efficiency (NUE) were significantly lower with the high fertilizer dose (300-150-150 kg NPK ha-1)... |

Optimum planting methods better ensure water and nutrient supply through improved root development resulting in better crop growth and productivity. This study was conducted to evaluate the effects of planting methods on root development, crop allometry, water use efficiency (WUE), productivity and economic returns of different maize (Zea mays L.) hybrids. Maize hybrids NK-6621, Pioneer-30Y87, and Pioneer-30Y58 were sown on beds, ridges, and flat surface. Ridge sowing was better followed by bed sowing; while amongst the hybrids, 'Pioneer-30Y87' performed the best. Well-developed root system, with longer primary root, more number of lateral roots and higher root growth rate, was observed in 'Pioneer-30Y87' planted on ridges, which led to higher WUE, grain... |
