title: Agronomic performance and land equivalent ration in cassava and sweet potato arrangements plants

description: ABSTRACT Two or more cultures intercropped can have the best soil use, an alternative to reduce losses and increase income. This study aimed to evaluate the agronomic performance of cassava intercropped with sweet potato in different arrangements and determine the Land Equivalent Ratio (LER). The experimental design was randomized blocks with five treatments and five replications. The treatments were: C (cassava monoculture); 2C:1P (two cassava rows intercropped with one sweet potato row); 1C:1P (one cassava row intercropped with one sweet potato row); 1C:2P (one cassava row intercropped with two sweet potato rows) and P (sweet potato monoculture). Each experimental plot consisted of 6 or 8 rows with 7 m length spaced 0.9 m from each other, and the experimental plots were separated by a 2.0 m space. The following were evaluated: commercial yield, individual fresh weight, length, diameter and dry mass of roots. The data were compared by Tukey test at 5% probability. The cassava highest yields occurred in C and 2C:1P, while the sweet potato highest yield was in P. The treatments did not differ significantly for individual fresh mass, length, diameter and dry mass of cassava root. In sweet potato, the treatment 1C:2P resulted in lower value of fresh mass and individual root diameter. There was also advantage of intercropping over monoculture because all arrangements with the intercropping promoted a LER value greater than 1. Thus, cassava intercropped with sweet potato results in better utilization of environmental resources compared to monoculture.

title: Yield and quality of three types of melon, varying the number of fruits per plant

description: ABSTRACT The purpose of this study was to evaluate the characteristics of yield and quality of three types of melon, bearing one and two fruits per plant. The experiment was conducted from September to December 2013, in the Greenhouse Sector belonging to Unioeste, Campus Marechal Cândido Rondon - PR. The experimental design wasrandomized blocks in a factorial scheme 3 x 2, with six replications. In the first factor the melon types (canary melon, net melon, frog skin melon) were allocated and in the second factor, the plants with different number of fruits (one and two fruits per plant). The characteristics evaluated were fruit mass, longitudinal and transversal diameters of fruit and locule, thickness of the endocarp, fruit and locule shape index, soluble solids, pH, titratable acidity, fruit firmness, ratio and productivity. The fruits obtained from plants with one and two fruits showed higher fruit fresh mass and increased productivity, respectively. The frog skin melon type had higher fresh fruit mass and productivity. The ratio was influenced by the number of fruits per plant for the canary melon type. The net melon type showed a reduction in acidity compared to the other types, regardless of the number of fruits maintained per plant. The thickened pulp was found in fruits of plants with only one fruit. The fruit and locule shape index were not influenced by the number of fruits per plant. Regardless of the number of fruits and the type of melon, the soluble solids content was higher than the minimum recommended for marketing.

title: Vegetative, productive and qualitative performance of grapevine "Cabernet Sauvignon" according to the use of winter cover crops

description: ABSTRACT To study the effect of winter cover crops on the vegetative, productive and qualitative behavior of "Cabernet Sauvignon" grapevines, an experiment was conducted in two wine harvests by sowing different species of winter cover crops and additional treatments with manual weeding and mechanical mowing in an experimental vineyard located at the Experimental Station of Epagri in Videira, state of Santa Catarina, Brazil. Plant attributes of the grapevine, such as number of rods and weight of pruned material and number of branches per plant. At the time of skin color change, petioles of recently matured leaves were collected for analysis of the levels of N, P, K, Ca, Mg, Fe, Mn, Zn and B. Moments before harvest, 100 grape berries were collected randomly to determine the total soluble solids, titratable acidity and pH. At harvest, the number of bunches per branch, the number and mass of clusters per plant and the average mass of clusters per plot were determined. Fresh and dry matter yields of the cover crop and weed plants were also determined when coverage reached full bloom. The winter cover crops did not alter the yield and quality of "Cabernet Sauvignon" grapes and showed no differences from each other for the management of spontaneous vegetation by hand weeding or mechanical mowing. Rye and ryegrass are effective alternatives for weed control alternatives. The species of white and red clover present difficulty in initial establishment, producing a small amount of biomass.

title: Quality of Moringa oleifera Lam. seedlings cultivated in substrates with green coconut fiber and organic compounds

description: ABSTRACT Moringa oleifera Lam. is a vegetal species with great potential to use as food, medicine and forage as well as water clarifying and decontamination agent, biofuel, among others. Low cost techniques for seedling production using regional residues are useful to introduce this species in low-income communities. This research aimed to evaluate the nutritional responses and growth of moringa seedlings cultivated in substrates with different concentrations of green coconut fiber (GCF) associated to organic compounds (OC). The experiment was performed in randomized blocks. Two organic compounds were tested: the urban waste compost (UWC) and earthworm compost (EC) associated with GCF in various volumetric proportions (OC: GCF): 0: 100; 25:75; 50:50; 75:25 and 100:0%. The data after 51 days of cultivation showed that the increase of the concentration of GCF in relation to the organic compound decreased height, dry biomass, Dickson Quality Index and the contents of N, P, K, Ca and Mg of the seedlings. There was no difference for these characteristics between the use of UWC and the EC. The substrate with 100% of GCF without complementary fertilizers caused symptoms of N deficiency in the moringa seedlings.

title: Cowpea yield on soils with residues of NPK and natural phosphate fertilizers in succession the area of degraded pasture

description: ABSTRACT The cultivation of cowpea [Vigna unguiculata (L) Walp] can be an important alternative in succession to maize in areas of degraded pastures due to the use of residue from fertilizers . With this, we aimed to evaluate the productivity of cowpea as a successor culture to undergo corn doses of reactive natural phosphate Arad and combinations with NPK. The experimental design was a randomized block design in a split plot with four replications. The fertilizer was applied in previous cultivation (crop) using four phosphate doses in the form of Arad natural phosphate: 50, 100, 200 and 300 kg ha-1 of P2O5 and the sub-plots in combination with NPK, NK, NK + liming, and control (no liming and fertilizer). The cowpea yield components were evaluated in this work. The residues of P2O5 from the natural phosphate increased the phosphorus content in the plant and influenced the number of grains per pod. The residual effect of NK+ liming and only NK showed better results for the variables grain yield, number of pods per plant, number of seeds per pod and dry mass of aerial part. The residual effect of NPK showed better results for the mass of 100 grains.

title: Growth and productivity of sesame in entisol as a function of organic and mineral fertilization

description: ABSTRACT In sesame crop, the average grain yield is around 650 kg ha-1, but its production potential is 1500 kg ha-1 with an appropriate fertilization program and water availability. The objective of this research was to verify the response of two sesame cultivars to organic and mineral fertilizers and their effects on productivity, final growth of biomass and some yield components of sesame. A field experiment was conducted with the BRS Seda and CNPA G4 cultivars, fertilized with five organic sources, plus two relative controls, fertilized with ammonium sulfate, in four replications, totaling 48 plots. The experimental design was a randomized block, with 12 treatments in a factorial scheme (5 x 2) + 2. The results were submitted to analysis of variance, Tukey test, and analysis of principal components and clustering. In fertilizations with organic sources, the equivalence of 80Kg of N/ha was considered. The following characteristics were evaluated: plant height, capsules per plant, stem diameter, dry biomass, seeds per capsule, seed yield per plant, productivity, among others. The nutrient sources were statistically significant for productivity, while the cultivars present significant effects for mass of a thousand seeds. In relation to productivity variables and dry biomass, there was no statistical difference among cultivars. Sesame cultivars responded similarly to organic fertilization in large part from verified variables.

title: Evaluation of Maillard Reaction intensity, Physical-chemistry Attributes and Texture Analysis in "Dulce de Leche"

description: ABSTRACT The Dulce de Leche, a product which is marketed and produced in Latin America, is much appreciated by consumers, with great importance for the Brazilian market. The standardization of the characteristics of this product as well as the suitability for recommendations of the Technical Identity and Quality Regulation becomes difficult due to the large cultural diversity and technological changes. In this context, the study of physical-chemical and rheological characteristics the Dulce de Leche becomes of great importance to achieve such uniformity, mainly by the lack of technical and scientific literature about this product. This work aimed to evaluate and relate the physical-chemical and texture attributes. Twelve Dulce de Leche brands were analyzed to moisture, water activity and texture analysis with statistical analysis of the data. Descriptive statistical analysis for texture attributes showed high variability between samples. As for the moisture content, 51.11% of the samples were outside the statutory standards. The analysis had results of free HMF and elevated totals. Through the Principal Component Analysis (PCA) it was found that the main source of variation and contribution to group of the appraised brands is related to the elements that make up the rheological characteristics of the product. The results showed high correlation between water activity, moisture and rheological attributes. The combination of physical, chemical and rheological attributes were shown to be useful for characterization and evaluation of Dulce de Leche quality. These results expand scientific knowledge about Dulce de leche favoring the dairy industry and the scientific community.
