“…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.…”

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...

“…In the cultivation of chives (condiment), Araújo Neto et al (2010) observed that productivity was 43% higher in soil covered in weed mulch than in uncovered soil. Sediyama et al (2011) founded an increase of 20% in the productivity of beets in soil covered with coffee bean husks.…”

“…The growth of vegetable crops under no-tillage on straw of cover crops has been stimulated, aiming at the sustainability of natural resources in vegetable crop production. Researches have been implemented to increase the sustainability of the production of vegetable crops, such as lettuce (Hirata et al, 2014), green onion (Araújo Neto et al, 2010), and coriander (Tavella et al, 2010), among others, in no-tillage systems. Some studies have shown that different cultivars of a vegetable crop can differ for their adaptability to the same production system (Meagy et al, 2013;Resende et al, 2016), and that it is important to assess the compatibility of cultivars to a reduced soil tillage.…”

The objective of this work was to evaluate the adaptability of different lettuce (Lactuca sativa) cultivars grown in no-tillage on straw of ruzi grass (Urochloa ruziziensis), as well as its effects on soil temperature and weed control, in successive cultivations in the summer. The treatments were carried out in a randomized complete block design, with four replicates, in a split-plot arrangement (2x4), in which soil management (no-tillage on ruzi grass and convention tillage) was the main plot, and the different crisphead lettuce cultivars (Amanda, Solaris, Vanda, and Vera), the subplots. No difference was observed between cultivars for soil management. No-tillage reduced the soil temperature by up to 3.7°C and weed density by 3.7 times, in comparison with conventional tillage. Ruzi grass promoted a greater bed conservation. In comparison to with conventional tillage, the no-tillage management of lettuce cultivated on ruzi grass straw resulted in a lower yield in the first crop due to excess straw; in a similar yield in the second crop; and in a greater yield in the third crop. Lettuce cultivated on ruzi grass straw in no-tillage management results in a greater sustainability, in comparison with conventional tillage, in three successive plantings.

“…The protected environment, which was once used more intensively for the flowers production, now expands to the cultivation of fruits, especially during the seedling stage. Araújo-Neto et al (2010) report that the protected environment of seedlings involves climatic modifications that change the environment-plant-substrate relations. These changes may have a positive or a negative impact in plant growth.…”

It is aimed to evaluate the effect of cattle manure, and ground crushed cassava branches based substrates in the growth of 'Formosa' papaya seedlings under different environmental conditions. Four protected environments were tested: greenhouse in arched, covered with polyethylene film with a thermo reflective screen underneath it; similar greenhouse but without the reflective screen; monofilament nursery with 50% shade screen and thermo reflective nursery with 50% shade screen. In the protected environments, seedlings were accomodated in polyethylene bags (15.0 x 25.0 cm) were filled with cattle manure, and ground cassava branches based substrates in the following proportions: 100% cassava branches; 80% cassava branches and 20% cattle manure; 60% cassava branches and 40% cattle manure; 40% cassava branches and 60% cattle manure; 20% cassava branches and 80% cattle manure and 100% cattle manure. Because there was no repetition of the culture environment, each one was considered as an experiment. The substrates with 80 and 100% cattle manure promoted better growth. The cassava branches alone is a poor substrate. The black screened and the thermo reflective proved to be the best environments.
