Semi-decomposed chicken manure on Chinês and Macaquinho taro yield - DOI: 10.4025/actasciagron.v25i1.2609

Abstract

Chinês and Macaquinho taros and doses of 0; 7; 14; 21 and 28 t ha^-1 of semi decomposed chicken manure - CFC were studied, aiming to know the fresh mass plants yield, in Dourados, state of Mato Grosso do Sul, Brazil, in a Dystrorthox soil, arranged as 2 x 5 factorial scheme in a randomized complete block design with four replications. The harvest was done 225 days after the sowing. Average yields of leaf fresh masses were not influenced by clones/CFC doses interaction, they did not vary among clones, and were neither influenced by doses of CFC incorporated into the soil. Corm (RM) production of Macaquinho clone (4.56 t ha-1) was 65.2% higher than Chinês (2.76 t ha-1). There was an increase of RM yield, varying from 22.6% (14 t ha^-1) to 72.3% (28 t ha^-1), with the CFC use in relation to treatment with 0 t ha^-1. Large and medium cormels (RF) production of Macaquinho and Chinês corresponded to 89.9% and 84.6%, respectively, of total production of RF.
