Gália Melons Production in Protected Environment Under Different Irrigation Depths

ABSTRACT:The study aimed to evaluate the "Gália" melons productive characteristics grown in greenhouse under different irrigation levels, and conducted with and without soil cover by plastic mulching. Experiments I (WC) and II (WtC) were conducted simultaneously in a protected environment, using a completely randomized design (CRD), where plants of Gália melons (Hybrid Nectar cv.) received five levels of water depth defined by 50, 75, 100, 125 and 150% of evapotranspiration (water requirement), with four replications, differing only by utilization (WC) or not (WtC) of plastic mulching. The results showed that the variables productivity, average weight, length and diameter of the fruits were affected by different levels of water replacement in the soil regardless the use or not of the soil cover. The largest reductions in productivity 46.32 and 32.03% were observed for the treatment of 50%, compared to the treatment of 100% for experiments I (WtC) and II (WC), respectively.

“…The beneficial effect provided by the soil covering, such as reduction in weed infestation (SILVA et al, 2009), reduction of soil temperature (OLIVEIRA et al, 2005), greater nutrient availability (OLIVEIRA et al, 2008), greater microbial biomass (WANG et al, 2008) and greater water economy (OLIVEIRA et al, 2005;MOTA et al, 2010), which promote greater yield in other crops like chives (ARAÚJO NETO et al, 2010) and beets (SEDIYAMA et al, 2011), did not translate into better performance for onion. The use of a protected environment, the residual effect of the succession of organic management in the area and the efficient control of irrigation may have neutralized the effect of the soil coverings.…”

“…Despite the beneficial effect of mulch soil covering in the reduction of weed infestation (SILVA et al, 2009), in the reduction of soil temperature (OLIVEIRA et al, 2005), in nutrient availability (OLIVEIRA et al, 2008), in the increase of the microbial biomass of the soil (WANG et al, 2008;LEE, 2010) and in improved water economy (OLIVEIRA et al, 2005;MOTA et al, 2010), the effect of the use of soil coverings on crop production depends on three other factors: the physical, chemical and biological traits of the material (SEDIYAMA et al, 2011) that can increase the productivity of vegetables (LEE, 2010). Thus, it is advisable that the use of mulch soil covering must be regionally adapted, and that, in addition to being technically possible, must be economically viable.…”

Abstract:The soil preparation in horticulture, including organic, is characterized by intense soil tillage, which increases energy costs and unbalanced the environment. The organic system in onion cultivation has shown satisfactory results, however the soil covering use tends to improve the cultivation environment and may result in higher yields. The objective of this work was to evaluate the performance of onion cultivars in organic cultivation under different soil coverages. The experiment was conducted in the period of April to October of 2009, under protected cropping, in the experimental area of the horticulture sector of the Universidade Federal do Acre (UFAC), in Rio Branco, Acre, Brazil. A randomized block design was adopted, in a split-plot arrangement, the plots being comprised of soil coverings: coffee bean husks, grass straw (Brachiaria decumbens); dessicated bamboo leaves (Bambusa spp.) and uncovered soil (control treatment), and the subplots comprised of three onion cultivars (IPA 10, IPA 11 and IPA 12), with four repetitions. The variables analyzed were total bulb yield (t ha -1 ), marketable bulb yield (t ha -1 ), fresh mass of the bulb (g bulb -1 ), classification of the bulbs and loss of mass as a function of storage time. There was no interaction effect between the soil coverings and the cultivars. Cultivars IPA 10 and IPA 11 showed greater agronomic performance of the studied variables. The soil coverings did not affect the yield and average mass of the bulbs under organic cultivation. The three cultivars presented more than approximately 70% of the bulbs in class 2 and a maximum of 5% of unmarketable bulbs. The loss of mass after 49 days of storage was 10% independent of the cultivar or soil covering.Key words: Allium cepa. Organic agriculture.

O cultivo de cebola em sistema orgânico tem mostrado resultados satisfatórios, todavia o uso de cobertura do solo tende a melhorar o ambiente de cultivo, podendo resultar em maior produtividade. O objetivo deste trabalho foi avaliar o desempenho de cultivares de cebola em cultivo orgânico sob diferentes coberturas do solo. O experimento foi conduzido no período de abril a outubro de 2009, em cultivo protegido, na área experimental do setor de olericultura da Universidade Federal do Acre (UFAC), em Rio Branco, Acre, Brasil. Adotou-se delineamento experimental em blocos casualizados, com arranjo em parcelas subdivididas, sendo as parcelas constituídas pelas coberturas de solo: casca de café, palha de gramínea (Brachiaria decumbens); folha de bambu dessecada (Bambusa spp.) e solo descoberto (tratamento controle), e as subparcelas constituídas pelas três cultivares de cebola (IPA 10, IPA 11 e IPA 12), com quatro repetições. As variáveis analisadas foram produtividade total de bulbos (t ha -1 ), produtividade comercial dos bulbos (t ha -1 ), massa fresca do bulbo (g b...

“…It is important to point out the homogeneity of the soil in the area (Table 1), which in this case was not an expressive source of variation to affect the results, i.e., the variation in the data for water storage in the 0.0-0.3 m layer was due to the applied treatments, as well as other factors, such as variations in water distribution via irrigation. Details of the discussion on the variation of water storage in the soil of this experiment are presented by Mota et al (2010).…”
