Productivity agro-economic Peruvian carrot in response to addition of broiler manure in soil.

Abstract

The aim of this work was to evaluate the agricultural economic yield from Peruvian carrot 'Yellow of Carandaí ', in response to addition of broiler manure on the soil. The treatments were the result of combinations of doses (1, 6, 10, 14 and 19 t ha-1) and addition forms (and incorporated coverage) of litter, ground chicken determined using the experimental matrix Plan Puebla III. The experimental design was randomized blocks with four replications. Evaluated the fresh and dry weight of leaves, shoots, crowns, marketable yield and unmarketable. We also counted the numbers of shoots, roots marketable and nonmarketable and made the diameter and length of marketable and non-marketable yield. Highest yields of leaves and crowns (7.97 and 7.04 t ha-1) were obtained under treatments 19 SA/19 IS and 19 SA/1 IS, respectively, increased to 47.30 and 35.94% when compared to lowest values by treatments 6 SA/1 IS and 6 SA/14 IS, respectively. Fresh mass of marketable roots was not significantly influenced by the studied factors, its highest average yield (22.08 ton ha-1) and net income (R$ 43,475.76) were attained under 19 SA/14 IS t ha-1 of broiler manure. Greatest length of marketable roots (98.16 mm) was attained under 9.19 SA/11.56 IS ton ha-1, increased to 50.37 mm compared to the smallest one using 19 SA/1 IS. Thus, under conditions in which the experiment was carried out, it leads to conclude that the combination among doses and addition methods of broiler manure enabled the rise productivity of marketable roots and net income; thereby to obtain higher net income the Peruvian carrot growth should be done by adding broiler manure split as 19 ton ha-1 surface applied and 14 t ha-1 incorporated to the soil.
