The soil of the experimental area was classified as Haplic Gleysol, usually cultivated with vegetables. Crotalaria juncea, known as sunn or sunn hemp, is a tropical Asian plant of the legume family (Fabaceae). 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. Helpful in nematode management. Seropédica: UFRRJ. For green manure purpose, April to July is optimum time for sowing. Australian Journal of Plant Physiology 13: 699-756. 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. Method of sowing Broadcasting method is used in case of green manure purpose and seed drill is used when … Cultivo orgânico de taro (Colocasia esculenta) entre faixas de guandu na Região Serrana Fluminense. 0000029901 00000 n Taro harvest took place in April 2003, and tillers average mass, number of tillers per plant, and yield of tillers and central rhizomes were measured. Saia oats (black oats) and Sunn Hemp are the two main cover crops grown around the world, and for good reason. We are a shop who sale a green manure seed such as sunn hemp, jack bean, cowpea, pigeanpea etc. Gliessman (2005) emphasized that the choice for monoculture in a determined area can create problems proceeding from the increase of the susceptibility to pests, biodiversity reduction, and a less efficient use of the available natural resources, such as water, light, and nutrients. (1996) observed identical phenomena in cassava plants raised between intercalated rows of Pigeon pea (Cajanus cajan) and leucaena (Leucaena leucocephala).

Sowing Depth Sowing depth should be 3-4 cm. The use of leguminous plants as green manure, besides the Nitrogen provision which comes from the process of biologic fixation for cultures of economic interest, limits the erosion risks and lessens the competition impact with spontaneous plants (Espindola et al.,2005). Season. Dhaincha Seed. However, in the treatment in which the sunn hemp was kept unpruned the persistence or the reappearing of two species was identified: goosegrass and tropical spiderwort (Commelina benghalensis), the latter in lower frequency. The dry weight of sunn hemp, of which the stem occupies the largest proportion, was higher than that of peanut at time of incorporation. The aerial biomass of the sampled plants was also assessed. It bears yellow flowers and elongate, alternate leaves. It is now widely grown throughout the tropics and subtropics as a source of green manure, fodder and lignified fiber obtained from its stem. By the time of the sunn hemp cutting, an assessment of the nitrogen biologic fixation was made through the method of the natural isotopic abundance 15N (Shearer & Kohl, 1986). Regarding the physical characteristics of the soil, it was noticed, 150 days after planting the taro (30 days after the sunn hemp cutting) that the soil temperature was lower in the treatment in which taro was intercropped with the sunn hemp without pruning than in the other treatments (Figure 1). For seed purpose use row spacing of 45 cm. Quando a crotalaria foi cortada rente ao solo, houve um acúmulo de 211 kg ha-1 de N, além da reciclagem de, em média, 17 kg ha-1 de P, 85 kg ha-1 de K, 151 kg ha-1 de Ca e 27 kg ha-1 de Mg. Observou-se ainda a deposição de 6,85 Mg ha-1 de matéria seca. SEND EMAIL. 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. 565 p.         [ Links ], VILPOUX O.

GST No. (2018) evaluated the taro-sunn hemp intercropping with the leguminous plant cut in different periods. When intercropped with sunn hemp without cuttings, taro plants experienced a decrease in the number of tillers per plant and consequently a reduction in productivity. Sunn hemp growing in a field. Alley cropping on an Ultisol in subhumid Benin. It also presents the results for green manure cover crop trials at the Great Basin Plant Materials Center, with two forage soybean Glycine max varieties; 'Big Fellow' and 'Large Lad' and a tropical legume, sunn hemp Crotalaria juncea 'Tropic Sunn'. Sunn Hemp (Crotalaria juncea L.) is a multipurpose tropical and subtropical legume grown in many countries, notably India, mainly for its high quality fibre. 2004. TrustSEAL Verified. A randomized blocks design with four replicates was used and the soil of the field plots was classified as Haplic Gleysol. 0000008403 00000 n Using a winter cover crop/green manure is a conservation practice that Sunn hemp suppresses weeds, slows soil erosion, and reduces root-knot nematode populations. The use of sunn hemp as green manure intercropped with taro allowed a considerable addition of Nitrogen to the system. 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). It can reach 6 to 10 feet tall, depending on soil fertility. When planted as a summer annual it regularly produces 2.5 tons of biomass and 120 lbs N/acre. 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. The taro was planted in double rows spaced by 1.0 m. The planting furrows had a space of 0.5 m, with rhizomes placed at every 3.0 m. The experimental plot consisted of four 3.0 m rows and the useful area corresponded to the five central plants in each of the two central rows. Sunn Hemp is used for green manure forage, organic soil building and cover crop applications. green manures build soil OM, and several other benefits green manures can provide in a crop rotation.

Independente do manejo da crotalária, as plantas de taro apresentaram maior área foliar e foram mais altas quando cultivadas em consórcio do que em monocultivo. Even when the sunn hemp was pruned, with its respective biomass left on the soil, there was a significant reduction of the spontaneous plants throughout the following month, comparatively to the plots with taro in monoculture. Ca and Mg contents were also determined by atomic absorption spectophotometry, after the referred nitricperchloric digestion (Bataglia et al., 1983). Métodos de análise química de plantas. This document synthesizes information about the warm-season cover crop, sunn hemp.

Sunn hemp, Crotalaria juncea L. is popular as a green manure in many tropical and subtropical areas in the world as an organic nitrogen source. Used as a cover crop, Sunn Hemp can improve soil health, decrease soil erosion, improve water retention, and recycle plant nutrients. This behavior might be associated to the light income restriction, inducing a physiological plant response that resulted in leaf blade increase and petiole elongation. It is generally considered to have originated in India. Mesmo quando cortada a meia altura, a crotalária ainda forneceu 60% de nutrientes em relação ao tratamento em que foi cortada rente ao solo.
