title: Effects of grain-producing cover crops on rice grain yield in Cabo Delgado, Mozambique

description: ABSTRACT Besides providing benefits to the environment such as soil protection, release of nutrients, soil moisture maintenance, and weed control, cover crops can increase food production for grain production. The aim of this study was to evaluate the production of biomass and grain cover crops (and its respective effects on soil chemical and physical attributes), yield components, and grain yield of rice in Mozambique. The study was conducted in two sites located in the province of Cabo Delgado, in Mozambique. The experimental design was a randomized block in a 2 × 6 factorial, with four repetitions. Treatments were carried out in two locations (Cuaia and Nambaua) with six cover crops: Millet (Pennisetum glaucum L.); namarra bean (Lablab purpureus (L.) Sweet), velvet beans (Mucuna pruriens L.), oloco beans (Vigna radiata (L.) R. Wilczek), cowpea (Vigna unguiculata L.), and fallow. Cover crops provided similar changes in chemical and physical properties of the soil. Lablab purpureus, Vigna unguiculata, and Mucuna pruriens produced the highest dry matter biomass. Vigna unguiculada produced the highest amount of grains. Rice grain yields were similar under all cover crops and higher in Cuaia than Nambaua.

title: Base temperature for florets opening and anthochron in gladiolus

description: ABSTRACT Gladiolus is an important cut flower in national and international markets. The floral stem, a kind of spike, is composed of florets that have acropetal opening. Knowledge on the opening speed of florets, represented by the anthochron, can assist in planning harvesting and marketing activities. The objectives of this study were to estimate the base temperature for floret opening in gladiolus and to determine the anthochron, with the time unit represented by the thermal time. Two field experiments were conducted in Santa Maria, RS, Brazil, for two years (2011-2013), each experiment composed of 12 planting dates and three cultivars. The daily thermal time (STd) was calculated as the difference between the daily mean temperature and the base temperature (Tb) and the accumulated thermal time was obtained by the sum of STd. To estimate the Tb for floret opening, we used the number of open florets (NFA) collected in the experiments. We concluded that the Tb for floret opening in gladiolus is 6 °C and for the anthochron is, on average, 14.7 ºC day per floret, but the anthochron Tb varies according to solar radiation during spike flowering period.

title: Genetic diversity among bitter palm populations in the state of Goiás

description: ABSTRACT Bitter palm is a palm tree species that produces bitter core, which is too appreciated in cooking and can be used in animal feeding, as well as in landscaping, but it is still little studied, which hinders strategies for its cultivation and breeding. The present work aimed at evaluating the genetic divergence among bitter palm populations of three municipalities of Goiás and quantifying the relative contribution of eight characteristics in the diversity, using multivariate procedures. Twenty-four individuals from three populations were analyzed, with individuals from three plants with 30 and 36 months of age. The characteristics evaluated were: stipe diameter, number of definitive leaves, plant height, length of first green leaf, number of leaf sheaths, length and weight of heart of palm, and diameter of heart of palm base. The genetic diversity of the populations was evaluated by Tocher’s grouping method based on the dissimilarity matrix obtained by standardized mean Euclidean distance and the principal component analysis with graphical dispersion in the Cartesian plane. The results demonstrated the existence of genetic variability and heritability estimates of high magnitude for plant height, leaf length, stalk diameter at 10 cm soil, number of heart of palm sheaths, and core diameter of heart of palm. The performance of the grouping by Tocher’s method based on the dissimilarity matrix promoted the formation of eight groups, evidencing the influence of the geographical origin in the grouping and the selection in non-destructive characters of high genetic correlation as stalk diameter and leaf length can promote important gains in the production of heart of palm.

title: Yield of cotton as a second crop in narrow planting in response to nitrogen and potassium fertilization

description: ABSTRACT Nitrogen and potassium are the most required nutrients for cotton crop. Cotton grown as a second crop, after soybean harvesting, has been an option for crop system in the Brazilian savanna. This study aimed to evaluate the effect of N and K fertilization on the nutritional status and the yield components of cotton grown as a second crop, after soybean, and in a narrow planting system. The experiment was carried out adopting a completely randomized block experimental design. The treatments were set up in a 4 × 4 factorial arrangement with four replications. Factor A was the four N doses (0, 50, 100, and 200 kg ha-1) and factor B was four K2O doses (0, 40, 80, and 160 kg ha-1), applied as side-dressing. The N and Mg concentration levels in the leaf increased linearly with the N doses, while the concentration levels of S and Fe decreased (quadratic effect). The K2O doses resulted in positive and negative effects on K and Mg, respectively, in the leaf. The N fertilization promoted higher lint yield response when compared with K fertilization, as lint yield rate per kg of N was twice the yield rate per kg of K2O. The highest lint yields were reached with 148 kg ha-1 and 107 kg ha-1 of N and K2O, respectively.

title: Phytochemical characterization of soybean oil with addition of Portulaca oleracea L. extract

description: ABSTRACT The main objective of the present work was to measure the total phenolic compound content and antioxidant activity of Portulaca oleracea L. extract, besides evaluating the oxidative stability and phytochemical compound retention present in soybean oil plus synthetic (TBHQ and BHT) and natural (Portulaca oleracea L. extract) antioxidants. The treatments soybean oil (SO), soybean oil plus 100 mg/kg TBHQ (TBHQ), soybean oil plus 100 mg/kg BHT (BHT), and soybean oil plus 100 mg/kg extract (Extract) were subjected to thermo-oxidation at 180 ºC/5 h. The extract presented 99.5 mg EAG/100 g of total phenolic compounds and 84.6, 35.5, and 1.8µM Trolox/100 g of antioxidant activity to DPPH, β-carotene/linoleic acid system, and FRAP, respectively. The oxidative stability for the Extract treatment was inferior to TBHQ, which showed the longest induction period (7.6 h). After heating, TBHQ and Extract treatments presented higher capacity of tocopherol and phytosterol retention, reaching values over 88 and 87%, respectively. Similar percentages of polyunsaturated fatty acids were found in SO and Extract treatments. The purslane extract in the 100 mg/kg concentration reduced the alterations suffered by soybean oil after heating and it can be used as a natural substitute for synthetic antioxidants.

title: Isotonic regression analysis of Guzerá cattle growth curves

description: ABSTRACT The objective of this study was to apply data transformation via isotonic regression in growth curves studies of Guzerá cattle whose data presented disturbances characterized by decreased body weight in certain age groups. Weight-age data were collected on newly weaned Guzerá males according to the methodology of weight gain tests (WGT) defined by the Brazilian Association of Zebu Breeders (ABCZ). The Logistic, Von Bertalanffy and Gompertz models were fitted to weight-age data using the generalized least squares method for non-linear regression models through the Gauss-Newton algorithm. The proposed transformation based on isotonic regression theory proved to be efficient; and the Logistic model was the best to describe the growth of animals, with a high percentage of convergence (100%) and goodness of fit assessed by the mean squared error (MSE) and the coefficient of determination (R2).
