The reduction in spacing and higher plant densities, has been used by farmers in order that the new genotypes are more productive, justifying the increase of crop yield. The study was conducted to evaluate the effects of different row spacings and maize hybrids for yield components and crop productivity in the Cerrado region of Mato Grosso do Sul. The experiment was carried out at the University of Aquidauana - State University of Mato Grosso do Sul, the land area classified as Alfisol. The statistical design was randomized blocks in factorial (6 × 2) with four replications. The treatments consisted of combinations of two row spacings (0.45 and 0.90 m) and six hybrids (AG 9040, DKB 330, Pioneer 30F35, 2B707, 2B688 and 2B433). The results indicate no interaction between hybrids and spacing and that the largest spacing increased ear length and number of rows of the spike. Source

The leucaena is a leguminous that has high protein content and digestibility, can be supplied fresh or made into hay. The objective was to verify the influence of dehydration time of leaves and fine stems of leucaena and storage time on their chemical-bromatological characteristics. Cutting the fractions to be haymaking (leaves and stems smaller than one centimeter) was deposited on a plastic canvas for dehydration, being collected samples of the material at 0, 4th, 8th, 24th and 48th hours of dehydration to determine the levels of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), total carbohydrates (TC), not fibrous carbohydrates (NFC), ether extract (EE) and mineral matter (MM). The bales of hay were made using a manual baler and were kept stored in environment shaded, ventilated and protected of rain for 90 days. In that bales also were collected samples monthly to determine if occurred losses in nutritional quality. The dehydration time for 24 hours and storage for 30 days in water and allowed to dry to obtain the best chemical-bromatological composition of leucaena hay. The levels of CP, NDF, EE and MM decrease as function of drying time and storage both during the rainy as in the dry season, while the DM, TC and NFC increased due to these variables for both periods. © 2015, Universidade Federal de Uberlandia.

The cabbage crop is cultivated in small areas and requires much labor, this crop being mostly driven by family farmers. This study aimed to evaluate the effect of boron levels in different cultivars of cabbage in western Mato Grosso do Sul state, Brazil. The experiment was carried out at the Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Aquidauana. The experimental design was randomized blocks in factorial scheme 2 × 5, two cultivars and five doses of boron, with four replications. We evaluated the following features: boron foliar plant area, plant height, number of outer leaves, fresh weight of outer leaves, leaf content of boron, plant area, plant height, number of outer leaves, fresh weight of outer leaves, dry weight of outer leaves, classification according to head weight, compactness and yield per hectare. The cultivar 60 Dias showed higher values for yield components and consequently greater productivity. The application of boron influences linearly in the boron content of leaves, head diameter and number of inner leaves. The boron levels interfered the yield of cabbage, the maximum dose for '60 Dias' being 7.2 kg ha-1 and the minimum necessary dose for the cv. Chato de Quintal being 1.06 kg ha-1. Source

The identification of the probability distribution function for the representation of the monthly rainfall is relevant in agricultural planning, mainly regard to the establishment of crops. The aim of this work was to verify the probability distribution (exponential, gamma or normal) which best fits to data monthly rainfall of 14 sites in the state of Mato Grosso do Sul. Rainfall data of 14 stations (sites) of the State of Mato Grosso do Sul it were obtained from the National Water Agency (ANA) database, collected in the period 1975 - 2013. At each of the 168 time series of monthly rainfall was applied the Kolmogorov-Smirnov test to assess the fit to probability distributions exponential, gamma and normal. The normal probability distribution presented the best fit to monthly rainfall series of Mato Grosso do Sul and it can be used for the estimation the monthly rainfall, especially in the rainy season months (October to March). The exponential probability distribution can be used for the estimation of monthly rainfall in the driest months of the year (May to September). Thus, we recommend that these distributions be used in future research, aimed to estimate the probable rainfall for the Mato Grosso do Sul State. © 2016, Universidade Federal de Uberlandia.

With the aim of to evaluate the correlation and the direct and indirect effects of morphological descriptors on oil content of castor (Ricinus communis L.) genotypes, an experiment was conducted in the agricultural years 2010/2011 and 2011/2012 at Universidade Estadual de Mato Grosso do Sul – Unit of Aquidauana (UEMS/UUA). The experimental design used was randomized blocks with three replications. The treatments consisted of seven castor genotypes (BRS Energia, IAC-2028, IAC-Guarani, BRS Nordestina, BRS Paraguaçu, IAC-80 and IAC-226). The following descriptors were evaluated: plant height (PH), stem diameter (SD), number of bunches (NB), number of fruits (NF), mass of fruits (MF), mass of hundred seeds (MHS) and oil content (OC). Initially, it was determined the following genetic parameters: genotypic variance, environmental variance, coefficient of experimental variation, coefficient of genotypic variation, heritability, environmental correlations, phenotypic correlations and genetic correlations. The phenotypic correlations were deployed by path analysis in estimates of direct and indirect effects, and preceded the diagnosis of multicollinearity in explanatory variables and independent explanatory variables on the OC (primary dependent variable). The results indicated that the direct and indirect selection of genotypes with plant height, stem diameter, number of bunches and mass of hundred seeds is promising to select genotypes with high oil content in castor. © 2015, Universidade Federal de Uberlandia.
