O melao (Cucumis melo L.) tem grande importância para a economia nacional, fazendo-se necessario o conhecimento sobre as praticas de manejo adequadas, de modo a facilitar a conducao de sua cultura, sem comprometer a produtividade e a qualidade dos frutos. O objetivo deste trabalho foi avaliar a qualidade fisico-quimica e a produtividade de tres tipos de melao, conduzidos com um e dois frutos por planta. O experimento foi realizado de setembro a dezembro de 2013, no Setor de Cultivo Protegido, da Unioeste, Campus de Marechal Cândido Rondon. O delineamento adotado foi o de blocos ao acaso, em esquema fatorial 3 x 2, com seis repeticoes. No primeiro fator, foram alocados os tipos de melao (Amarelo, Rendilhado e Pele de Sapo) e, no segundo, o numero de frutos (um e dois frutos por planta). Os frutos foram avaliados quanto a massa media, aos diâmetros transversal e longitudinal do fruto e do loculo, a espessura da polpa, ao indice de formato do fruto e do loculo, aos solidos soluveis, ao pH, a acidez titulavel, a firmeza, a ratio e a produtividade. Frutos obtidos de plantas conduzidas com um e dois frutos apresentam maior massa media e maior produtividade, respectivamente. Meloes do tipo pele de sapo apresentaram maior massa media de fruto e maior produtividade. A ratio foi influenciada pelo numero de frutos mantidos por planta, para melao do tipo amarelo. Melao do tipo rendilhado apresentou reducao de acidez, em comparacao com a dos demais tipos, independentemente do numero de frutos por planta. A maior espessura da polpa foi encontrada em frutos de plantas conduzidas com um fruto por planta. Os indices de formato do fruto e do loculo nao foram influenciados pelo numero de frutos por planta. Independentemente do numero de frutos e do tipo de melao, o teor de solidos soluveis foi superior ao minimo recomendado para comercializacao.

The objective of the present work was to evaluate gas exchange and its influence on productivity and quality of melon cultivars conducted with one and two fruits per plant. The experiment was conducted from September to December, 2013. The experimental design was of randomized blocks in factorial design 3 x 2 with six replications. In the first factor were allocated the melon cultivars, belonging to types canary melon, net melon and frog skin melon; and the second factor was the conduction of plants with one and two fruits per plant. Three melon cultivars were used for each type. The evaluations were performed at 40 and 56 days after transplanting. The characteristics evaluated were: CO 2 assimilation rate (A), transpiration (E), stomatic conductance (gs), the internal CO 2 concentration (Ci). From these measurements was calculated water use efficiency (EUA). The soluble solids content was determined by direct reading, while the average fruit weight was measured at harvest, estimating productivity. With the results, it can be concluded that differences in gas exchange indexes to cultivars of frog skin melon type have no influence on productivity and soluble solids content. To cultivars of canary melon and net melon types is recommended the Goldex and Louis cultivars respectively. Independent of cultivar is recommended cultivation with two fruits per plant, because its higher productivity and did not change the indices of gas exchange in plants.

This work aimed to study the influence of plant spacing and level of basal leaves defoliation on yield characteristics of tomato. The experimental design was a randomized complete block design in a factorial 2x4 with five replications. Two spacings (0.30 and 0.50 m) and four levels of defoliation (0, 50% and 100% of basal leaves removed after fruiting the first cluster and 100% of basal leaves removed after harvest of the first cluster). It was evaluated the number of normal, defective and total fruits per cluster, mass of normal, defective and total fruits per cluster, longitudinal and transversal diameter of the normal fruits; and productivity of normal and total fruits per cluster. Removing the basal leaves is favorable for production, when there is a higher plant density, and must be performed before the formation of the first cluster. For more spaced plants the basal leaves influenced these characteristics, not being favorable their removal during the formation of the first cluster, but after sampling this. Defoliation is a practice that can be used to increase aeration, improving the utilization of solar radiation and reduce pest problems.

An important aspect in the cultivation of vegetables is the quality of the product to be marketed, free from dirt and damage and the practice of mulching could be an option, but there is scarse information. The aim of this study was to evaluate the influence of mulching on the production traits of three cultivars of Pak Choi. The experiment was set up during March to May 2013 using a split plot randomized block design, with four replications. Soil cover treatments (white agrotextile, black agrotextile, black plastic, silver plastic, tifton straw and bare soil) were arranged in the plots, and three cultivars of Pak Choi (Green Pak Choi, White Pak Choi and Chingensai Natsu Shomi) in subplots. Height and diameter of shoots, number of leaves, fresh weight of the head and petiole, base diameter, dry weight of stem, petiole, and leaf were evaluated thirty-five days after transplantation. The total dry weight and leaf area were measured, and then we estimated the yield. There was a significant effect of soil cover and cultivar. In general, the cover with synthetic materials showed higher values on production of Pak Choi. The cultivar White Pak Choi was better adapted to the growing conditions, with an average yield of 57.78 t/ha.

Plant growth promoting substances, either from biological or chemical origin, are widely used in modern agriculture. In this context, this study evaluated the physiological quality of maize seed treated with thiamethoxam and inoculated with Azospirillum brasilense . Initially, we tested bacterial growth on medium with increasing concentrations of thiamethoxam. We also evaluated the physiological quality of seeds through morphometric measurements, emergence speed index and chlorophyll content by SPAD through a 2x3 factorial arrangement with seed inoculation with A. brasilense (100 mL per 25 kg of seed) and three doses of thiamethoxam (0, 80 and 120 ml per 60,000 seeds). Bacterial population showed a linear reduction according to increasing doses of thiamethoxam. The dose of 120 ml thiamethoxam (42 mg active ingredient) caused a decrease in several variables, while, the inoculation proved a positive activity in seedlings physiological quality. Thus, the inoculation combined with 80 ml thiamethoxam (28 mg active ingredient) show synergistic action in early development in maize seedlings.
