Experiment with Biol of Sugarcane Byproducts for greater Ecological Performance in Lettuce Cultivation (Lactuca Sativa L.)

Abstract

This research deals with the use of residues derived from sugar cane, to reduce contamination in the soil. The objective is to determine the appropriate concentration (ml of biol / l of water) of biol, for the highest yield of lettuce. The fertilizer was obtained from the composition of 16.5 kg of stubble, 16.5 kg of guano guinea pig, 11 kg of bagasse and 11 l of stillage. 
The completely randomized block design statistical model consisting of 5 treatments including the control and the standard dose was used: T1 with 0.0, T2 with 250, T3 with 500, T4 with 750, T5 with 1000 ml of biol over 200 l of water. It was evaluated in the field and laboratory.The obtained data were operated with the analysis of variance and Duncan.
The results determined that the T5 with 12.02 tn / ha of yield, in plant length with 26.92 cm, with a weight per lettuce 165.83 g, and an equatorial diameter of 24.80 cm. However, T4 obtained greater root length with 9.00 cm. In foliar analysis, T5 with 1000 ml of biol obtained a low concentration of the elements (N, P, K and others), however, this amount influenced lettuce yield.
