CARACTERÍSTICAS AGRONÔMICAS DE MILHO CULTIVADO EM DIFERENTES ARRANJOS POPULACIONAIS Objetivou-se determinar a resposta de diferentes arranjos populacionais sobre o desempenho agronômico do milho. O experimento foi realizado no Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso (IFMT),Campo Novo do Parecis O delineamento experimental foi o de blocos casualizados, em esquema fatorial 5 x 2, sendo cinco populações do híbrido simples DKB 390 VT PRO3 (50.000; 60.000; 70.000; 80.000 e 90.000 plantas ha-1) e dois espaçamentos entre linhas (0,45 e 0,90 m), com quatro repetições. Foram avaliadas características vegetativas e reprodutivas do milho. Os dados obtidos foram submetidos à análise de variância e análise de regressão. O aumento na população de plantas do milho incrementa a massa verde e a massa seca ao mesmo tempo em que reduz a massa de mil grãos (80.000 plantas ha-1), comprimento e diâmetro de espigas e número de fileiras por espiga de milho. O reduzido espaçamento entre linhas (0,45 m) e a população de 50.000 plantas ha-1 apresentaram os melhores resultados para as características reprodutivas, com menor variação de comportamento entre as populações avaliadas.Palavras-chave: desempenho agronômico, espaçamento entre plantas, população de plantas, Zea mays. ABSTRACT: The objective of this study was to determine the response of different population arrangements on the agronomic performance of corn. The experiment was carried out in Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso (IFMT), Campo Novo do Parecis. The experimental design was a complete randomized block in a 5 x 2 factorial scheme, with five populations of single hybrid DKB 390 VT PRO3 (50,000, 60,000, 70,000, 80,000 and 90,000 plants ha-1) and two row spacings (0.45 and 0.90 m) with four replications. The experiment evaluated the vegetative and reproductive characteristics of corn. Data were submitted to analysis of variance and regression analysis. The raise in corn plant population increases the fresh mass and the dry mass while reducing the mass of a thousand grains (80,000 plants ha-1), length and diameter of the ears and number of rows per corn ear. The reduced row spacing (0.45 m) and the population of 50,000 ha-1 plants presented the best results for reproductive characteristics, with lower variation in behavior among the populations evaluated in the experiment.Keywords: agronomic performance, plant population, spacing between plants, Zea mays.

Studies addressing the interaction of different spatial arrangement in soybean are needed in order to achieve management that leads to higher grain yield associated with rational seed use. The objective of this work was to evaluate the yield components and productivity of an undetermined growth type soybean as a function of different row spacing and plant densities. The treatments consisted of three row spaces (0.25, 0.35 and 0.45 m) and three plant population densities (30, 40 and 50 plants/m²). There was no interaction of row spaces and plant population on soybean yield. Regarding the overall spacing average, the grain yield of the population of 30/m² plants was higher than the productivity of the populations of 40 and 50/m² plants. The largest populations reduce plant sizes due to greater competition between plants. In addition, smaller populations promote higher individual plant yields due to the increase components of the production. This characteristic is defined as the ability of the plant to change its morphology and yield components in order to adapt to the conditions imposed by the spatial arrangement.

In 1957-58 and 1958-59, Virginia Bunch and Natal Common peanuts were sown on Tippers clay loam at Katherine, N.T., in a multifactorial experiment at two inter-row spacings (2 ft and 3 ft), four plant populations (10, 20, 40 and 80 thousand per acre) and two dates. In 1960-61, Natal Common only was sown at the same inter-row spacings, at two dates, and at populations of 10, 20, 30 and 40 thousand per acre. Over two seasons, the yield of Virginia Bunch kernels was not significantly influenced by variation in population, though the yield of hay was 42 per cent higher at 80,000 plants per acre than at 10,000 plants per acre. Kernel yields from 2 f t rows were 14 per cent higher than from 3 f t rows. In the first two seasons, the yield of Natal Common kernels was lower at 80,000 plants per acre than at 40,000 plants per acre. Over three seasons, maximum kernel and h g yields were achieved at 40,000 plants per acre ; the kernel yield at this population was 35 per cent greater than at 10,000 plants per acre. With early-planted Natal Common, 2.ft rows gave an 11 per cent higher yield of kernels than 3 f t rows, but with later planting there was no significant effect of inter-row spacing. The optimum economic seeding rates were estimated approximately as 30 lb an acre for Virginia Bunch and 45 lb an acre for Natal Common.
