O experimento foi conduzido na área experimental do Departamento de Engenharia da Universidade Federal de Lavras, Lavras/MG. A cultivar utilizada foi a Vereda, variedade Inodorus, e a irrigação da cultura foi por gotejamento sendo aplicada quatro lâminas, com turno de rega de dois dias. A evapotranspiração da cultura (ETc) foi calculada com base na evaporação do tanque classe A reduzido (ECA) a as lâminas líquidas (LL) aplicadas foram equivalentes a 0,5.LL, 0,75.LL, 1,0.LL e 1,25.LL. Cada parcela foi composta de 3 linhas com oito plantas por linha. Foi considerado planta útil as seis plantas da linha central de cada tratamento. As características avaliadas foram a altura de planta e diâmetro do caule, o peso médio, o diâmetro longitudinal e transversal dos frutos colhidos das plantas úteis de cada tratamento. O peso médio e os diâmetros longitudinal e transversal dos frutos não foram influenciados significativamente pelas lâminas aplicadas, entretanto apresentou tamanho abaixo do exigido pelo mercado. A altura e o diâmetro do caule tendem a ser maior na lâmina de irrigação equivalente a 0,75LL. UNITERMOS: lâmina de irrigação, Cucumis melo L., peso de fruto, LIMA, E.

GROWTH AND PRODUCTION OF MELON CULTIVATED IN GREENHOUSE UNDER DRIP IRRIGATION   2 ABSTRACT The objective of this study was to evaluate the effect of different irrigation depths on melon growing in greenhouse. The experiment was conducted in an experimental area of the Engineering Departament of the Universidade Federal de Lavras, Lavras/MG. Melon (Cucumis melo L., var. Inodorus, cv. Vereda) was drip irrigated, in a two-day interval, with four different depths. Crop evapotranspiration (ETc) was calculated with a reduced class A pan evaporimeter (ECA). Irrigation depths were input using four different fractions of the net depth (LL): 0.5.LL, 0.75 LL, 1.0.LL and 1.25.LL. Each irrigation treatment was applied to three plants rows, each one containing 8 plants. Only 6 plants located at the central row of each treatment were used for measurement. Evaluated parameters were: plant height, stem diameter measures, average weight and fruit longidutinal and transversal diameters. Average weight and fruit longidutinal and transversal diameters were not significantly affected by irrigation depth; however, they  presented smaller size  than the one demanded by the market. Plant height average and stem diameter average measurements showed tendency to be higher on the irrigation depth equivalent to 0.75.LL. KEYWORDS: irrigation depth, Cucumis melo L., fruit weigth.

The objective of this study was to evaluate the effect of different irrigation depth on initial development of Coffea canephora seedlings. The study was carried out at the farm Perobas, in the municipality of Rio Bananal, Espírito Santo, Brazil. The experimental design was completely randomized, with five treatments, comprising different depths of irrigation, being: 5, 7.5, 10, 12.5 and 15 mm dia-1. At 55 days after planting the seedlings were evaluated for characteristics:stem diameter, plant height, dry mass of aerial part and dry mass of the root system. The stem diameter and dry mass of the root system presented an inverse behavior to the increase of the irrigation depth. The plant height and dry mass of aerial part presented an increasing effect in relation to the variation of the irrigation depth. The 5 mm dia-1 irrigation depth provides the best result for development in the initial stages of the root system of the seedlings, while the irrigation depth of 15 mm dia-1 favored a greater accumulation of dry mass of aerial part of the seedlings.

One of the main problems faced in corn cultivation, especially in Cerrado regions, is the deficiency of micronutrients. Among the micronutrients essential for the development of plants, boron (B) stands out for participating in a series of physiological processes. Based on this, the present work aimed to evaluate the performance of corn under fertilization with different sources and doses of boron. The randomized block design in a 4x3 factorial scheme was used. Four boron doses (0, 1, 2, and 3 kg ha-1) and three nutrient sources (boric acid, borax, and ulexite), applied in topdressing, were evaluated. Plant height (cm), stem diameter (mm), first ear insertion height (m), ear length (cm), ear diameter (mm), number of rows per ear, number of grains per row, 1000-grain weight (g), and grain yield (kg ha-1) were evaluated. It was concluded that the boron sources and doses used did not influence the results of plant height, first ear insertion height, number of rows per ear, and grain yield. The three doses evaluated provided increases in stem diameter, with a dose of 2.08 kg ha-1 being the one with the highest average. The application of borax and ulexite results in higher values of ear diameter, number of grains per row, and 1000-grain weight. The dose of 1.74 kg ha-1 of boron provides the highest 1000-grain weight.

While supermarkets devote whole aisles to hybrids, traditional varieties are hard to find, and becoming scarcer day by day. Unfortunately, countless old melon varieties have already been lost. Luckily we succeded in collecting most of these varieties, and thus conserving them in Gene Banks. Landraces, local types, and old breed races show many characteristics that could be useful in organic farming. It is important to get acquainted with these varieties and cultivars, because they have greatly adapted to the climatic and pedological conditions of the Carpathian basin. Therefore their conservation is essential for the protection of Hungarian genetic variability. With the help of utilising our landraces in organic farming; careful selection; and the usage of marketing strategy in order to enhance quality features, such as unique flavour; we could reclaim the one-time excellent reputation of Hungarian melon.

E-mail: [email protected]  1 RESUMO  Neste trabalho, estudou-se o efeito da água com diferentes níveis salinos em termos de condutividade elétrica (CE = 1,1; 2,5 e 4,5 dS.m-1) e duas frequências de irrigação (1 e 2 dias) na produção da cultivar de melão do tipo HoneyDew (Orange Flesh) e a do tipo cantaloupe (Trusty), em solos de textura franco-arenosa na Fazenda São João Ltda, município de Mossoró-RN. Adotou-se o delineamento experimental em blocos ao acaso no esquema fatorial 3x2x2 com quatro repetições. Dos resultados obtidos, concluiu-se que mesmo sob estresse, a produção de melão irrigado com águas nos níveis salinos de 1,1 dS.m-1 até 2,5 dS.m-1, consegue-se produções economicamente viáveis em relação ao irrigado com as águas de 4,5 dS.m-1. A cultivar Orange Flesh mostrou ser mais sensível aos efeitos dos sais que a Trusty em todos os parâmetros avaliados, demonstrando ser esta última medianamente tolerante aos efeitos deletéricos, reduzindo sua produtividade apenas no nível salino 4,5 dS.m-1, em conformidade com a literatura.  UNITERMOS: Cucumis melo L., salinidade, produção, freqüência  BARROS, A.

MELON PRODUCTIVE BEHAVIOR IN RELATION TO WATER SALINITY AND IRRIGATION FREQUENCY  2 ABSTRACT  This work has studied the effect of different water salinity levels in terms of electrical conductivity (CE = 1.1; 2.5 and 4.5 dS.m-1) and two irrigation frequencies (1 and 2 days) on HoneyDew (Orange Flesh) and cantaloupe (Trusty) melon production, in loam sand soils in São João Ltda farm, municipal district of Mossoró-RN. The experiment was a 3x2x2 factorial randomized block design with four replications. The results allowed to conclude that even under stress, irrigated melon production at 1.1 dS.m-1 up to 2.5 dS.m-1 saline level water , make production economically feasible in relation to the one at 4.5 dS.m-1 saline level water. Orange Flesh seemed to be more sensitive to the salt effects than the Trusty cultivar in all appraised parameters. Trusty cultivar has shown to be reasonably tolerant to the deleterious effects, decreasing its  productivity only at  4.5 dS.m-1 saline level , which is according to the literature.  KEY-WORDS: Cucumis melo L., salinity, production, frequency

Cucumis Melo L

Anti-mitotic agents such as colchicine have been used to induce polyploidy in various plants. On the other hand, vincristine and vinblastine are also antimitotic agent extracted from Periwincle (Catharanthus roseus [L] G. Don) were previously studied to produce autotetraploid on shallot tuber (Allium cepa L.). Therefore, in this study phenotype character and ploidy of muskmelon (Cucumis melo L.) produced by etanolic extract of periwikle leaves were determined. The effects of different concentration of etanolic extract of periwinkle leaves on polyploidy induction in muskmelon were examined. Melon seedling of two days old were immersed in 0.5%, 0.1%, and 0.05% for 8 hours. Then seedling was grown on the polybag and a drop of each concentration of periwinkle leaves’s etanolic extract was added into apical shoot.  Melon seedling of ten days old were moved and cultivated and harvested on 60 days after cultivation. Phenotypic character such as: plant high, stem diameter, leaf area, fruit weight, fruit area around, flesh fruit thickness, skin fruit thickness, fruit horizontal diameter, fruit, vertical diameter, number of seeds, weight of 100 gram of seed, seed leght, seed width, and seed thickness were examined. The ploidy degree was determined by count of chromosome number root tips of second generation muskmelon sprout. Result of this study revealed that 0.05% etanolic extract of periwinkle leaves for 8 hours immersed is optimum concentration to induce autotetraploid muskmelon (4n=48). Autotetraploid phenotypic character of muskmelon produced by 0.05% etanolic extract of periwinkle leaves were generally bigger than control plants statistically significant in stem diameter, leaf area, and fruit horizontal diameter. The result also showed that the chromosome number of second generation autotetraploid muskmelon sprout was tetraploid (4n=48).

Rockmelon (Cucumis melo L.) belongs to the Cucurbitaceae family, which can adapt to various soil and climate areas, especially in Malaysia. The production of rockmelon in Malaysia has highly declined, and for this reason, farmers have opted to use the concept of soilless cultivation due to it benefits accrued from soilless media such as cocopeat, perlite, and burnt rice husk. The study was carried out to determine the effect of different growing media on the physical morphology of rockmelon seedlings. This experiment was set up using RCBD arrangements with four replications. Different growing media used were: (i) 100% Black Soil (BS), (ii) 75% cocopeat + 15% burnt rice husk + 10% perlite (M1) and (iii) 75% cocopeat + 20% burnt rice husk + 5% perlite (M2). The parameters measured were plant height, number of leaves and total leaves area, and stem girth. The data were collected within two weeks after transplanting. The parameters measured were subjected to ANOVA and LSD was applied to compare means. In this study, rockmelon seedlings treated on BS showed significantly (P<0.001) the highest plant height, number of leaves per plant, and total leaves area and stem girth. Seedlings on soilless M1, however, grew in slightly good conditions, as it showed the insignificantly higher values on morphological parameters measured. Thus, BS is still suitable for better use of media for 15 days old rockmelon seedlings (after transplanting). It gives the optimum conditions for adapting seedlings to the new exposure environment.

The plots were the irrigation depths: 60; 80; 100; and 120% of the culture evapotranspiration (ETc), the subplots were five doses of the Stimulate® biostimulant: 0; 0.6; 1.2; 2.4 and 4.8 L ha-1, and the sub-plots were two growing periods: hot and cold. The variables total and commercial productivity, the average weight of the commercial fruit, total soluble solids (SST), pH, total titratable acidity (ATT) and pulp firmness (FP) were evaluated. The dose of 4.8 L ha-1 with a depth of 120% of ETc, in the hot period, promoted better conditions of development and, consequently, a greater increase in productivity compared to the cold period of the Brazilian semiarid region. The quality of the fruits was influenced by the higher SST content in the hot period and ATT in the cold period, submitted to a dose of 4.8 L ha-1 of Stimulate® and to the depths below 100% of the crop evapotranspiration.   Keywords: periods; irrigation, Cucumis melo L., productivity, fruit quality
