The objective of this work was to evaluate the physiological quality of seeds of different cultivars of beans in terms of densities. The experiment was conducted at the Experimental Farm Unimontes in Janaúba, MG, with sowing in March 2011. The experimental design was a randomized block in factorial 4 x 5 with four replications. The treatments consisted of four bean cultivars of different growth habits (Ouro Vermelho, Ouro Negro, BRSMG Madrepérola and Manteigão Vermelho) and five densities (100, 200, 300, 400 and 500 000 plants ha-1). The seeds were evaluated for water content, germination and vigor tests (seedling emergence, speed of emergence index and accelerated aging). Cultivars Ouro Vermelho, Ouro Negro and BRSMG Madrepérola produce better quality seed physiological, relative to cultivate Manteigão Vermelhão. Increasing the seeding rate did not affect the physiological quality of seeds of bean cultivars, with the exception of Madrepérola, where the population density up to 290 000 plants ha-1 is suitable for production of quality seeds under the conditions studied.

The objective of this study was to investigate the effect of shading and seed coating on the initial development of cultivars of Panicum maximum. The experiment was conducted in 2011 in the field of Plant Science, State University of Mato Grosso of Sul, Unit Aquidauana, and the soil of the area classified as dystrophic Alfissol. We used conventional seeds with high physical purity, and seed coated bonding material of macro and micronutrients. We used three cultivars of P. maximum: Tanzania, Mombasa and Massai. The cultivation environments consisted of full sun (C1) and a greenhouse with 50% shade (C2). Because there is no repetition of environments, each experiment was considered. For each culture environment, we adopted the randomized block design in a factorial 2 x 3 (two types of seed cultivars x three cultivars) with four replications, performing variance analysis and pooled analysis of individual experiments to compare the environments cultivation. We evaluated the following morphometric characters: plant height (PH), leaf blade length (LBL), number of tillers (NT) at 27, 40 and 54 days after sowing (DAS) and dry mass of shoots (DMS) and roots (DMR) at 60 DAS. The development environment provided better C2 cultivars of P. maximum. The coated seed treatment did not influence the variables measured, with the exception of NT. The cultivar Mombaca showed better development in relation to others, but for the parameter NP, the cultivar Massai obtained the highest values. © 2014, Association for Information Systems.

Aiming to identify quantitative descriptors directly or indirectly related to grain yield and to verify whether this relationship depends of the growth habit of soybean (Glycine max (L.) Merrill), an experiment was conducted at Universidade Estadual de Mato Grosso do Sul –Aquidauana Unit, in a soil classified as Ultisol sandy loam texture. The experimental design was randomized block with four replications. The treatments consisted of six soybean genotypes, being three determinate growth habit and three indeterminate. The following descriptors were evaluated: plant height (PH), first pod insertion height (PIH), number of ramifications per plant (NR), number of pods (NP), mass of hundred grains (MHG) and grains yield (YIE). The data of each parameter of genotypes with determinate and indeterminate growth habit for each genetic class were compared by t-test at 5% probability. The results obtained showed that genotypes with indeterminate growth habit are more productive compared to those who have determinate growth habit. It is recommended simultaneous selection of the descriptors NP and NR for genotypes with determinate growth habit and PH, NP and NR for genotypes with indeterminate growth. © 2015, Universidade Federal de Uberlandia.

The millet crop in recent decades has shown an increase in planted area, mainly in the Cerrado region. However, there are few studies related to the management and phytossociology of weeds in this culture. Thus, the objective of this research was to perform a phytosociological survey in millet under different soil managements in Savanna Sul-Mato-Grossense region. The experiment was conducted in the experimental area of Universidade Estadual de Mato Grosso do Sul – Unit of Aquidauana (UEMS/UUA), in Aquidauana-MS. The area is cultivated to five years with soybeans in first crop and corn in second. The experimental design was randomized complete block in a split-plot design consisting of four blocks with four replications. In the plots were used soil preparation systems (minimum tillage and no-tillage) and in the subplots was utilized the nitrogen fertilization at 50 kg ha-1 and absence of nitrogen on millet at 25 days after emergence (DAE). Were evaluated the parameters number of species (NS), total number and dry mass of weeds (TN and DMW, respectively), dry mass of millet (DMM) and frequency (F), density (D), abundance (A) and Importance Value (IV) of weeds. The no-tillage system provided greater dry mass of weeds, whereas the nitrogen resulted in a smaller total number of weeds (TN). Cynodon dactylon and Commelina benghalensis were the most predominant species on area. © 2015, Universidade Federal de Uberlandia.

The spatial arrangement of soybean plants affects the intraspecific competition for light, water and nutrients, which can change the biomass production, incidence of pests, diseases and weeds, plant lodging, and grain yield. This work aimed to evaluate the agronomic performance under different row spacing, plant densities and crossed rows. Two field experiments were carried out in Campo Mourão, Paraná State, Southern Brazil, using the randomized complete block experimental design, in a 3x3x2 factorial arrangement, with four replications. The treatments were formed by the combination of three row spacings (0.30, 0.45, and 0.60 m), three plant densities (300,000; 450,000; and 600,000 plants ha-1), and two row design (crossed or parallel rows). For all variables, interaction of the experimental factors was not significant. The row spacing of 0.45 m provided the highest grain yield in relation to 0.30 and 0.60 m. The density of 300,000 plants ha-1 showed higher yield of soybeans in late sowing. The crossed lines did not increase the productive performance in soybean.
