This study aimed at the evaluation of the management of the sunn hemp used as green manure, in intercropping systems, on taro performance in the edaphoclimatic conditions of Magé, Rio de Janeiro State. 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. 0000001641 00000 n 2nd edition. 2005. Sunn hemp is most commonly used as a green manure, where it is grown for 2 to 3 months before cash crop planting and then incorporated into the soil at early blooming stage. Significant differences among the factors studied were determined by variance analysis, using the F test. The cultivation of taro intercropped with green manure could contribute to the overcoming of such problems and consequently to improve yield. The useful area corresponded to the five central plants in each of the two central rows.

O solo da área experimental foi classificado como Gleissolo Háplico. Sunn‐hemp has potential to be utilized as an alternative to winter legumes for ground cover and as an N source for a subsequent corn crop in the Southeast. Furthermore, the volumetric humidity of the soil increased when the sunn hemp was kept without cuttings, which may represent a positive factor for the intercropped cultivation of sunn hemp and taro, if this is the sunn hemp management chosen. The use of the land to produce green manure requires the maintenance of agriculture fields without an economic return in the short run, which makes it unviable, mainly for family farmers. 0000001027 00000 n Sunn hemp has bright green, simple leaves that are 3 to 5 inches long, approximately 1-inch wide, and are arranged in a spiral around the stem. This finding could be explained by slower decomposition rate of sunn hemp when used as surface mulch as opposed to using as soil incorporated green manure (Reeves, 1996). Among the factors that limit its yield, particularly in organic systems, we may cite the competition with spontaneous plants and the leaf burning, caused by the direct incidence of solar rays (Oliveira et al, 2004). esculenta) and sunn hemp (Crotalaria juncea) cut close to the ground and pruned at the height of the canopy.

Worth mentioning, it represented also a deposition of 6.85 Mg ha-1 of dry substance. 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).

Alternativas para o manejo orgânico do taro (Colocasia esculenta L. Schott) em diferentes condições edafoclimáticas no estado do Rio de Janeiro. Although green manure brings several advantages for the production systems, many farmers have been reluctant in adopting it as a pre-cultivation method. 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). On the other hand, when the sunn hemp was pruned at soil level or pruned at mid-height, besides the benefits already shown in relation to the spontaneous vegetation control and protection against leaf burning, there was no reduction in the yield of tillers when compared to the monoculture. It is now widely grown throughout the tropics and subtropics as a source of green manure, fodder and lignified fiber obtained from its stem.

Therefore, it was shown that under this study conditions, carried out at a productive pole in Magé, the intercropping with sunn hemp is an alternative for taro cultivation. Fourteen species were identified forming the spontaneous vegetation of the experimental area, with a predominance of goosegrass (Eleusine indica), Bermuda grass (Cynodon dactylon), and hairy beggarticks (Bidens pilosa), which all together represented 90% of the collected samples. Sunn Hemp is NOT recommended for cool or short season climates. Such management of the sunn hemp in the intercropped system did not compromise the yield of taro. [ Links ], NOLASCO F. 1984.
