“…Increasing total yield (ton / fed.) with increasing chemical N fertilizer rates agreed with those obtained on pumpkin by Das and Swain (1977); Rajendran (1983), Swiader et al, (1988; Reiners and Riggs (1997) and Feleafel et al (2000) , on squash by Huett (1986); Huett and Dettmann, (1988), Hilal and Selim (1992); Abd-El-Fattah and Sorial (2000); and on melons by Buwalda and Freeman (1986). Application of organic manures had increased total yield.…”

during the two successive Autumn seasons of 2003 and 2004 . Squash Cv. "Eskandrany" was selected to study the influence of chemical N rates . organic manure and biofertilizers on yield of squash. Treatments were arranged in split split -plot design in complete randomized block with four replicates. Chemical N rates ( 0.0, 30, 45 and 60 kg N / fed. ) treatment were arranged at random in the main plots .Three organic manure treatments (untreated, chicken manure and sheep manure) were distributed at random in the sub-plots, while three biofertilizer treatments (untreated, T26, T16 ) were distributed at random in sub-subplots. All flowers parameters significant affected by chemical N rates and biofertilizers. All interactions among the studied factors had significant effect on flower characters. All yield parameters were significantly affected by the chemical N rates in both seasons, where 45 Kg. N / fed. was obtained the highest value of early yield (kg) / plant , while there is no different between 60 kg N / fed. and 45 kg N / fed. on number of fruits ,average weight of fruit (g.) and total yield (ton/fed.) . NO3 and NO2 concentrations were significantly affected by the chemical N rates in both seasons. T26 decreased NO3 and NO2 concentrations.

“…Iranian farmers have used pruning and thinning techniques to produce melons from ancient times. These techniques have been widely used to enhance fruit size, yield, and quality elsewhere (Baljee et al, 1982;Buitelaor, 1987;Duwalda and Freeman, 1986;Kashi and Abedi, 1999). For selection of fruiting vines and maintaining two fruits per plant, the main stem tip is pinched when young and melons will be set at the sixth or seventh node of the two primary branches.…”

Photosynthetic characteristics, concentrations of mineral elements in xylem sap, and some vegetative traits of ‘Khatooni’ melon were compared with those of melons grafted onto three Cucurbita rootstocks cvs., Ace, Shintozwa, and ShintoHongto, and trained with three methods: T1) no pinching and fruit thinning; T2) pinched to produce two lateral branches; and T3) pinched to two branches and all the flowers and lateral branches from lower nodes thinned. Internal CO2 and water use efficiency varied with rootstocks. Stem diameter of scions, aerial fresh and dry weights, mean fruit weight and yield, electric conductivity, pH, and sap volume per plant of grafted plants were higher in grafted melons than in the nongrafted ones. These traits were unaffected by training methods. Mineral concentrations varied considerably depending on the rootstocks and training methods used. Xylem sap collected from the decapitated stem base of grafted melons trained with T2 and T3 methods contained a higher amount of mineral ions, especially NO3−, PO43−, and K+, than did the sap from own-rooted plants. The increase in the mineral levels in sap resulting from grafting was most apparent in ‘Khatooni’ grafted onto ‘ShintoHongto’ rootstock.

“…Para a lâmina de água de 422,1 mm, correspondente à evaporação do tanque Classe "A", o rendimento máximo estimado seria alcançado com a aplicação de 383,5 kg.ha -1 de nitrogênio. Este valor é praticamente três vezes o obtido por Buwalda & Freeman (1986) para a cultura do melão.…”

ASPECTOS ECONÔMICOS DA PRODUÇÃO DE MELÃO SUBMETIDO A DIFERENTES LÂMINAS DE IRRIGAÇÃO E DOSES DE NITROGÊNIO Rodrigo Otávio Câmara Monteiro1; Raimundo Nonato Távora Costa2; Moisés Custódio Saraiva Leão2; José Vanglésio de Aguiar32Departamento de Engenharia Rural, Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo, Piracicaba, SP, rocamara@esalq.usp.br2Departamento de Engenharia Agrícola, CCA, Universidade Federal do Ceara, Fortaleza, CE3Instituto Brasileiro de Geografia e Estatística - IBGE. 1 RESUMO O lucro constitui o principal objetivo da empresa agrícola, portanto, o uso racional dos recursos disponíveis no processo de produção de forma a se obterem os mais altos níveis de rendimento econômico deve ser considerado. Água e nitrogênio merecem atenção especial dentre os fatores de produção, haja visto suas participações no custo total da cultura. O objetivo deste trabalho foi trazer informações de ordem econômica da produção do melão a níveis de água e nitrogênio em Pentecoste, CE, de setembro a dezembro de 2002. O delineamento experimental utilizado foi blocos ao acaso no esquema de parcelas subdivididas. Os tratamentos constituíram-se da combinação entre quatro lâminas de irrigação (W1=232,7; W2=334,7; W3=422,1; W4=567,8 mm) e quatro níveis de adubação nitrogenada (N0=0; N1=75; N2=150; N3=300 kg.ha-1), com quatro repetições. A máxima receita líquida estimada de R$ 3.353,24 foi obtida com um nível de rendimento de 25.384,3 kg.ha-1 de melão, utilizando-se 609,2 mm de água e 186,2 kg.ha-1 de nitrogênio. Para otenção do custo total mínimo de níveis de rendimento abaixo de 22.000,00 kg.ha-1, foi recomendado apenas o insumo água no sistema de produção, em face do alto valor unitário do nitrogênio em relação à água.

ECONOMIC ASPECTS OF A MELON PRODUCTION UNDER DIFFERENT WATER AND NITROGEN LEVELS 2 ABSTRACT The main objective of a rural company is profit, therefore the rational use of the available resources in the production system to reach high levels of economic income must be considered. Water and nitrogen deserve special attention among the production factors because their participation in the production total cost. The objective of this work was to supply economic information of a melon production under different water and nitrogen levels in Pentecoste, Ceara State, Brazil, from September to December 2002. The statistical design was completely randomized blocks in split-plots. The main treatments were four water depths (W1=232.7; W2=334.7; W3=422.1; W4=567.8 mm) with four levels of nitrogen (N0=0; N1=75; N2=150; N3=300 kg ha-1). The largest economic result was R$ 3,353.24 ha-1, obtained with 609.2 mm of water and 186.2 kg ha-1 of nitrogen, providing a yield of 25,384.3 kg ha-1. To obtain minimum total cost of productivities below 22,000.00 kg ha-1, only water factor in the production system was recommended, due to high unit value of nitrogen against water.
