Grasses $ 5.00. Taxonomy. 70 degrees is much better. The soil of the experimental area was classified as Haplic Gleysol, usually cultivated with vegetables. Sunn hemp suppresses weeds, slows soil erosion, and reduces root-knot nematode populations. Viçosa: UFV. Manufacturer of Green Manure, Hibiscus Seed & Sesbania Seed offered by Vijay Sai Trading Company from Gangawati, Karnataka, India. In addition to the nutrient supply, the use of taro intercropped with sunn hemp cut at soil level or pruned at mid-height represented efficient alternatives for controlling the spontaneous vegetation and for reducing taro leaf burning by solar radiation, without compromising the yield of taro. �,)���#-4B�w���V��J����+J2W����J�Y�. 78p. General results allowed us to conclude that intercropping taro with sunn hemp cut at soil level or pruned at mid-height represent efficient alternatives for the spontaneous vegetation control and for the reduction of taro leaf burning by solar radiation. Sunn hemp is also being looked at as a possible bio-fuel. When cut and incorporated into the soil as “green manure”, it provides a considerable amount of organic matter that will improve soil fertility and tilth. 0000009252 00000 n Sunn Hemp is a summer annual that performs well in sandy soils and other soil types that may be nutrient-poor as a result of intensive farming. 0000012027 00000 n Adubação verde com leguminosas. It has also been grown in Brazil and Bangladesh as a soil-improving crop. 2004. The biomass Nitrogen level was determined by the Bremner & Mulvaney (1982) method, whereas P, K, Ca, and Mg were quantified using the nitricperchloric digestion (Bataglia et al., 1983). When the sunn hemp was cut at soil level, an accumulation of 211 kg ha-1 of N was observed in its aerial biomass, 40% of this value (84 kg) proceeding from biologic fixation. Keywords: Crotalaria juncea, Colocasia esculenta, organic farming, leaf area, leaf burning, weed control. Furthermore, the incidence of leaf burning, due to the direct solar radiation over taro leaves was analyzed through a diagrammatic scale adaptation named Michereff, previously utilized by Oliveira (2004). O taro foi plantado em fileiras duplas espaçadas de 1,0 m. Os sulcos de plantio tiveram espaçamento de 0,5 m, com os rizomas colocados a cada 3,0 m. A parcela experimental consistiu de quatro linhas de 3,0 m, adotando como área útil as cinco plantas centrais em cada uma das linhas do meio. GST No. Alley cropping on an Ultisol in subhumid Benin. 2007;25(4):562-566 DOI 10.1590/S0102-05362007000400013 . The cultivation of taro intercropped with green manure could contribute to the overcoming of such problems and consequently to improve yield. Sunn Hemp (Crotalaria junicea L.) has two major advantages over the common cover crops used in the area. :ӫ����L��@VL@`膞\m�|����eau�{ʧ5�p��bLI8+�c�^�E�\����� 2. ed. The intercropping with sunn hemp influenced the number of tillers per plant and tillers productivity, without altering, however, tiller average mass and central rhizome yield (Table 3). Sunn Hemp is a rapid, fibrous growing plant - often reaching 6ft in height. The useful area corresponded to the five central plants in each of the two central rows. 2nd edition. Australian Journal of Plant Physiology 13: 699-756. (Tese mestrado). When cut and incorporated into the soil as “green manure”, it provides a considerable amount of organic matter that will improve soil fertility and tilth. This form of permaculture is particularly useful if you want to grow vegetables, fruits, or herbs.It’s suitable for use in large orchards or on small raised beds, and also attracts beneficial pollinators to your garden while repelling destructive pests. The use of sunn hemp as green manure intercropped with taro allowed a considerable addition of Nitrogen to the system. Journal Homepage. Season. Part II. When ploughed under at early bloom stage, nitrogen recovery is the highest. Quick growing green manure -cum-fibre crop; Does not withstand heavy irrigation or continuous water logging ; Soil. 0000012938 00000 n It is now widely grown throughout the tropics and subtropics as a source of green manure, fodder and lignified fiber obtained from its stem. (Tese mestrado). Season. Among the alternative practices to reach a broader diversity in the agroecosystem, we highlight green manure. Plow down the crop in the bud or early flowering stage (normally about 60 days from planting). Scientific Crotalaria juncea English Crotalaria Sunhemp Sunn hemp Dutch Crotalaria French Crotalaria German Crotalaria Ostindische Hanf. 0000001027 00000 n Saia oats (black oats) and Sunn Hemp are the two main cover crops grown around the world, and for good reason. It is a member of the legume family. Sunn hemp suppresses weeds, slows soil erosion, and reduces root-knot nematode populations. SEND EMAIL. Crop categories. O experimento foi desenvolvido no município de Magé, Região Metropolitana do estado do Rio de Janeiro, para avaliar a influência do manejo da crotalária (Crotalaria juncea), usada como adubo verde, na forma de consórcio, sobre o desempenho do taro.
