“…Therefore, hairy woodrose becomes a good source of organic fertilizer for small producers, considering that this green manure is available spontaneously in the region where the study was conducted. These results are in agreement with those obtained by Silva et al (2011), in cultivating beetroot in monoculture, fertilized with hairy woodrose, and with those determined by Oliveira et al (2011Oliveira et al ( , 2012 and Bezerra Neto et al (2014), in planting the tuberous vegetable carrot in sole crop, and intercropped with leafy coriander and arugula crops (Oliveira et al, 2017), both fertilized with hairy woodrose. The economic indicators for the production system of beetroot in sole crop, as a function of the quantity of hairy woodrose biomass incorporated into the soil, were submitted to regression analysis, with the purpose of optimizing their agro-economic efficiencies.…”

“…Among the species that have been tested is the hairy woodrose, a spontaneous plant of the family Convolvulaceae that is native to northeastern Brazil. This has a green phytomass productivity of around 36 t ha , S = 1.3 g kg -¹ and a C/N ratio of 18:1, presenting as an excellent alternative for use as green manure (Bezerra Neto et al, 2011;Linhares et al, 2012b;Oliveira et al, 2017). Bezerra Neto et al (2011), in studying the agronomic performance of lettuce as a function of different amounts of hairy woodrose incorporated into the soil, observed a higher productivity of lettuce leaf (10.26 t ha -1…”

Beetroot (Beta vulgaris L.) is a tuberous vegetable that is under experimentation in the vegetable production system in Rio Grande do Norte state (Brazil). It is quite demanding, in nutritional terms. One of the alternatives to meet this need is green manuring using spontaneous species of the Caatinga biome. The aim of the present work was to optimize the agro-biological performance and economic profitability of the beetroot 'Early Wonder', fertilized with different doses of hairy woodrose (Merremia aegyptia (L.) Urb.) in this semi-arid environment. Hairy woodrose is a spontaneous species of the Caatinga biome that is widely distributed, being found in forests, fences, forest clearings and fields, growing in soils of different textures, producing biomass with a high content of macronutrients. This material was collected from spontaneous vegetation, native to the region, and used as green manure.The experimental design was a randomized complete block, with four treatments and five replicates. The treatments consisted of four amounts of hairy woodrose biomass incorporated into the soil (10, 25, 40 and 55 t ha-1 of dry matter). The following agronomic characteristics were evaluated in each beetroot treatment: plant height, fresh mass of shoots, number of leaves per plant, dry mass of shoots and dry mass of roots, total and commercial root productivity, and root productivity classified into scrap and extra roots, extra A roots, extra AA and great roots. Apart from these characteristics, the following economic indicators were also determined for each treatment: gross income, net income, rate of return and profit margin. The maximum agro-biological efficiency of beet root productivity (22.68 t ha-1) was obtained from 44.92 t ha-1 of hairy woodrose biomass added to the soil. The maximum economic efficiency of the yield of beet roots was achieved as a net income of AU$2,491.00 (R$6,406.36) ha-1, provided by the production of 22.04 t ha-1 of commercial roots, using 37.03 t ha-1 of hairy woodrose biomass incorporated into the soil. The use of hairy woodrose as green manure presents agro-economic feasibility in beet cultivation in this semi-arid environment.

“…The increasing productivity per unit of area is one of the important reasons for cultivating two or more crops in intercropping system. According to Oliveira et al (2017), the cultivation of tuberous with leafy vegetables provides better use of the land and other available environmental resources, resulting in higher economic yield. Rezende et al (2005), estimating economic indicators in intercropping systems of radish with lettuce, obtained return rate of 4.13 and 4.53, and profit margin of 75.77 and 77.94% respectively, results these close to those obtained in this work.…”

The association of crops presents as one of the cultivation practices to be used in the systems of vegetable crop production in the northeast Brazil semiarid, fertilized with biomass of spontaneous species of the Caatinga biome as green manure. Under this approach, a study was performed during the period from June to December 2013, in the research area of the Experimental Farm belonging to the Universidade Federal Rural do Semi-árido, Mossoró, RN (Brazil), to assess the feasibility of the agro-economic efficiency of the radish × cowpea-vegetable association manured with different amounts of roostertree biomass in semiarid environment. A randomized complete block design was used with four treatments and five repetitions. The treatments were composed of four biomass amounts of roostertree incorporated to the soil (10, 25, 40 and 55 t ha-1 on a dry basis). The highest agronomic and economic efficiencies of the intercropping of radish with cowpea-vegetable were obtained with the incorporation of 53 and 47 t ha-1 of roostertree biomass added to the soil. The roostertree spontaneous species of the Caatinga biome it is showed as an efficient green manure in the association of radish with cowpea-vegetable.

Contudo, atualmente são escassos os estudos sobre SAFs irrigados. Desta forma, este trabalho teve como objetivo avaliar a produção da cultura da alface (Lactuca sativa L.) em cultivo solteiro e consorciado com rúcula (Eruca sativa L.) e rabanete (Raphanus sativus L.), no interior de um SAF e a pleno sol, sob irrigação por gotejamento. O estudo foi conduzido no Sítio Agroecológico da Embrapa Meio Ambiente, em Jaguariúna, SP. Os resultados demonstraram que o sistema de condução não influenciou o diâmetro horizontal da alface, enquanto o cultivo a pleno sol promoveu maior produção de massa seca e número de folhas de alface e rúcula. O rabanete apresentou folhas mais longas no SAF quando comparado ao pleno sol. O policultivo aumentou a produção por unidade de área, em 129,5% em média, em relação ao monocultivo no SAF e pleno sol. Estes resultados demonstraram que a consorciação foi vantajosa em relação ao monocultivo, ao produzir uma maior quantidade de hortaliças por unidade de área e insumos.

RESPONSE OF LETTUCE UNDER AGROFORESTRY SYSTEM WITH DRIP IRRIGATION 2 ABSTRACT Agroforestry systems (SAFs) commonly provide optimization of the cultivation area, labor, inputs and water, with yield diversification and stability, greater efficiency in weed control and soil protection against erosion. However, studies on irrigated SAFs are currently scarce. Thus, this work aimed to evaluate the production of lettuce (Lactuca sativa L.) in single cultivation and intercropped with arugula (Eruca sativa L.) and radish (Raphanus sativus L.), grown in an agroforestry system and in full sun. The study was conducted at the Sítio Agroecológico of Embrapa Meio Ambiente (experimental farm), in the city of Jaguariúna, in the state of São Paulo, Brazil. The results showed that the conduction system did not influence the horizontal diameter of lettuce, while cultivation in full sun promoted greater production of dry mass and number of lettuce and arugula leaves. The radish showed longer leaves in SAF compared to full sun. Polyculture increased production per unit area, by 129.5% on average, compared to monoculture in SAF and full sun. These results showed that intercropping was advantageous in relation to monoculture, as it produced a greater number of vegetables per unit area and inputs. Keywords: farming system, crop optimization, localized irrigation system.
