DOSES DE POTÁSSIO APLICADAS VIA FERTIRRIGAÇÃO POR GOTEJAMENTO SUPERFICIAL E SUBSUPERFICIAL NO MELOEIROCULTIVADO EM AMBIENTE PROTEGIDO  Inêz Gifone Maia Sales; Thales Vinícius de Araújo Viana; Valdemício Ferreira de Sousa; Benito Moreira de Azevedo; Solerne Caminha CostaDepartamento de Engenharia Agrícola, Universidade Federal do Ceará, Fortaleza, CE,  [email protected]  1 RESUMO Esta pesquisa foi desenvolvida com o objetivo de estudar os efeitos de três doses de potássio, aplicadas via fertirrigação por gotejamento superficial e subsuperficial, na produtividade do meloeiro (Cucumis melo L.). O trabalho experimental foi conduzido, de abril a agosto de 2002, em um ambiente protegido, em Limoeiro do Norte, Ceará. Utilizaram-se mudas do híbrido de meloeiro Bônus 2, espaçadas de 0,5 x 1,0 m, com tutoramento vertical, em espaldeiras de 2,0m de altura. Os tratamentos resultaram de combinações entre doses de potássio (40; 120 e 200 kg ha-1) e o local de aplicação (superfície do solo ou subsuperficialmente). O delineamento experimental foi em blocos ao acaso, com arranjo fatorial 2 x 3, com 4 repetições. Foram avaliadas quatro variáveis: número e peso médio dos frutos e produtividades total e comercial. A aplicação de adubos potássicos na subsuperfície via irrigação não proporcionou diferenças significativas, assim como as doses de potássio aplicadas. UNITERMOS: Cucumis melo L, estufa, irrigação localizada.  SALES, I.

POTASSIUM DOSES APPLIED BY FERTIRRIGATION USING SUPERFICIAL AND SUBSUPERFICIAL IRRIGATION IN NET MELON IN GREENHOUSE  2 ABSTRACT The purpose of this research was to study the effects of three doses of potassium application, under drip irrigation in two soil profile layers, on melon productivity (Cucumis melo L.). The experiment was carried out in a kind of chapel-shaped greenhouse, in Limoeiro do Norte, CE, Brazil, from April to August 2002. Bonus 2 hybrid young plants were transplanted, separated every 0.5 x 1.0m and vertically supported on 2.0 m high racks. The treatments were a combination of doses of potassium (40; 120 and 200 kg ha-1) and the following nutrient application depths: 0.0 m (surface) and 0.20 m (subsurface). The experimental design was made in randomized blocks with factorial arrangement 2 x 3 and 4 replications. The evaluated variables were: number of fruits, average fruit weight, total productivity and commercial productivity. The potassium fertilizer application on subsurface by irrigation did not provide significant differences, in comparison to a surface application; the potassium level increase from 40 kg ha-1 to 120 kg ha-1 and 200 kg ha-1 did not cause significant changes in the analyzed variables. Keywords: Cucumis melo L, greenhouse, drip irrigation.

This study aims to determine the effect of trimming with a wide variety of growing media hydroponic system fertigation on growth and yield of melon. Research will be conducted in the green house (House of plastic) UMSIDA Agriculture Faculty, Campus 2, Gelam, Candi, Sidoarjo, research time between the months of March to June 2016 using analysis of variance and continued test HSD 5%. The variables measured were plant height, leaf number, level of sweetness of fruit, fruit weight, high-fruit, thickness of the flesh of the fruit, conclusion from this research is going on the effect of trimming and a wide variety of growing media hydroponic system fertigation in treatment PM5 (trimming down, kokopit). There was also a real influence on the treatment PM6 (without pruning, kokopit) .In observation of plant height, leaf number, fruit weight, and high fruit. And also happens to influence a wide range of growing media on growth and yield of melon on hydroponics fertigation system, the PM6 treatment (without pruning, kokopit) had the highest rates in the observation of plant height, weight of the fruit, and the number of leaves.

Genetic variation among 378 melon (Cucumis melo L.) germplasm accessions collected in India in 1992 and 26 accessions in China in 1994 was evaluated with 19 isozyme loci. `Top Mark' and `Green Flesh Honeydew', which represented two distinct C. melo ssp. melo L. groups, Cantalupensis and Inodorus, respectively, were used as reference cultivars. Genetic distances among accessions were calculated, and an initial cluster analysis using these distances resulted in 148 groups of varying size, ranging from two to 47 accessions. One accession from each of the 148 groups was chosen at random and used in a second cluster analysis that identified 11 accession groups. Group 1 was unique and consisted of only two C. melo ssp. agrestis (Naudin) Pangalo accessions. Two large branches were detected at cluster node 2. One branch was comprised of three groups of 3, 12, and 34 accessions, while the other branch contained seven groups of 2, 3, 14, 16, and 47 accessions, and the reference cultivars. Of the 148 accessions, 132 were from 41 sites in Rajasthan and Madhya Pradesh, India, which were distributed unequally across the 11 groups. The 14 Chinese accessions originating from seven provinces were also dispersed unequally in the four major cluster groups. `Top Mark' and `Green Flesh Honeydew' were genetically distinct and uniquely clustered in the same group. These results indicate that additional collections of melon germplasm should be made in eastern and southern India.

ABSTRACT: Melon or muskmelon (Cucumis melo L.) is of considerable economic importance in Brazil. Nearly all the cultivars currently grown are hybrids. Heterosis has been used to advantage in the melon plant, and the use of uniform hybrids is one of the reasons for successful cultivation. The aim of the present study was to evaluate the agronomic potential of yellow melon lines and hybrids. An experiment was conducted in randomized blocks with three replications to evaluate 24 hybrids generated by crosses among three elite lines used as female parents (AF-01, AF-02, and AF-03) and eight lines used as male parents (LAM-01, LAM-02, LAM-03, LAM-04, LAM-05, LAM-06, LAM-07, and LAM-08). Yield and fruit quality traits were evaluated. Partial diallel analysis was carried out to estimate general combining ability and specific combining ability. Additive and non-additive effects were observed for the yield, mean fruit weight, and pulp thickness traits. The lines AF-02, LAM-02, and LAM-03 are the most promising as parents as they more frequently have favorable alleles. The most prominent hybrids in diallel analysis were AF-02 x LAM-02, AF-02 x LAM-03, AF-02 x LAM-04, and AF-03 x LAM-06.

Cucumis Melo L

The quality-oriented fruit production in well-controlled enclosed hydroponic systems has been greatly enhanced by the technology of precision agriculture. Over-fertilisation has been commonly applied to the traditional hydroponic culture of fruit crops, without considering different nutrient demands during development. Adjusting the nutrient formulations depending on crop developmental stages could enable efficient fertilisation to increase yield quality. In this study, N-reduced and K-modified nutrient solutions were applied for a two-step nutrient manipulation experiment, to improve the fruit quality (Experiment I) and optimise the fertilisation schemes (Experiment II) of hydroponic netted melon (Cucumis melo L. var. reticulatus). The N-reduced and K-modified treatments, before fruiting stage in Experiment I, obtained higher fruit quality with increased fruit weight, dry matter ratio, flesh thickness, and total soluble solids. In Experiment II, fruits cultured under treatment II-3 (applied with 100-75-100% N and 100-125-75% K during VG-PYF-FEM) had the highest overall preferences, with ‘rich’ aroma, ‘dense’ texture, and ‘perfect’ sweetness, compared to all other experimental treatments. Our study successfully improved the fertilisation schemes for a hydroponic netted melon with precise N- and K-nutrient formulations specific to different developmental stages. Our study promotes the future advancement of precise fertilisation to improve fruit quality and reduce environmental pollution from farming activities.
