Abstract:
The vegetables are highly demanding in readily soluble nitrogen fertilizers. Alternatively, organic practices, such as green manure, compost application, crop rotation and consortia are adopted in various management programs and soil conservation in several countries in order to regain fertility and reduce the use of mineral fertilizers contributing to a better sustainability. The experiment was conducted at Old Weir property located in the Rural Municipality of Pombal PB, from December 2012 to January 2013 aimed to evaluate the efficiency of carnauba straw as organic fertilizer in coriander in succession to the cultivation of carrot. The same design was used was randomized blocks with nine treatments and three replications. The treatments were (0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4 and 1.6 kg m-2 on a dry basis construction of carnauba straw ). Each plot consisted twelve rows of plants spaced 0.1 mx 0.05 m with five plants pit-1. An increase of 12.0 cm-1 on plant height was noted in the absence of fertilization (0 kg-m 2 plot) and the largest amount of straw, carnauba wax (1.6 kg m-2 construction), with a height average maximum of 17.4 cm plant-1. The number of stems per plant, there was a mean increase of 3.0 stems per plant between the smallest amount (0 kg m-2 of construction) and the highest (1.4 kg m-2 of construction), with maximum 7,5 rods plant 1. Fresh pasta coriander adjusted to a linear equation with an average value of 457 g m-2 of construction, equivalent to 9.0 bunches of coriander, with the application of 1.6 kg m-2 of construction of carnauba straw . The amount of 1.6 kg m-2 of construction of carnauba straw was what caused the greatest accumulation of fresh mass of coriander, with an average value of 457 g m-2 of construction, corresponding to 9.0 bunches of cilantro. The carnauba straw is decomposed into viable alternative to be used as organic fertilizer.
