“…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.…”

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.

“…Por exemplo, a altura de planta e os rendimentos de massa verde e de massa seca da rúcula, cuja família Brassicaceae e o ciclo de cultivo são os mesmos do rabanete, foram favorecidos com o aumento nas doses de C. procera (15,6 t ha -1 ), M. aegyptia (12,2 t ha -1 ) e S. obtusifolia (15,6 t ha -1 ), incorporadas aos 15; 20 e 30 dias antes do plantio, respectivamente (LINHARES, 2009). O desempenho agronômico da cenoura e da beterraba também foi maior com o crescente aumento nos níveis da adubação com M. aegyptia (15,6 t ha -1 ) e C. procera (45 t ha -1 ) sob parcelamento (OLIVEIRA et al, 2011(OLIVEIRA et al, , 2012SILVA et al, 2011SILVA et al, , 2013. Batista et al (2013) observaram que a dose superior dos adubos verdes M. aegyptia, C. procera e S. obtusifolia (21 t ha -1 ) possibilitou uma maior massa fresca de raiz comercial de rabanete (10,01 g planta -1 ) e redução na porcentagem de raízes refugo.…”

Intercropping system and the use of green manure with spontaneous species has been an alternative farming method applied to the productive sector of vegetables in the northeastern semi-arid region. The objective of this work was to determine which amount of Calotropis procera must be incorporated into the soil to provide the highest productive performance of the component crops and increase the profitability of the carrot and cowpea intercropping. The experimental design used was randomized complete blocks with five replicates. The treatments consisted of four amounts of C. procera incorporated into the soil: 10, 25, 40 and 55 t ha-1 on a dry basis. The characteristics evaluated in this intercropping system were: commercial productivity of carrot roots, yield of cowpea green grains, land equivalent ratios for component crops and for the intercropped system, score of the canonical variable of the association, and the economic indicators of gross income, net income, rate of return, and net profit margin. The maximum agronomic efficiency of the carrot x cowpea intercropping was reached at the land equivalent ratio of 1.12, using 43.39 t ha-1 of C. procera biomass incorporated in the soil, while the maximum economic efficiency of the carrot and cowpea crops association was obtained at the net income of R$ 17,856.43 ha-1, in the amount of 40.60 t ha-1 of C. procera biomass added to the soil.
