Abstract
ABSTRACT The use of organic fertilizers to improve the agronomic parameters of soy (Glycine max (L.) Merrill) has been considered a key production practice. During the period from December 2015 to May 2016, the productive behavior of Var-21 soya under the application of two organic biofertilizers was assessed in southern Haiti. Four random repetitions were carried out with biofertilizer A (cow dung + leguminous waste + ash + rice chaff) and biofertilizer B (cow dung + molasses + quick lime). The variables analyzed were days to flowering, plant height, number of beans per pod, weight of 1,000 beans, and yield per hectare, with statistical evaluation by analysis of variance and Tukey’s test. The best yield was obtained with biofertilizer A in treatment T2 (150 L/ha) (4,129.99 kg/ha). This study enabled us to identify the most efficient foliar fertilizer to improve the production parameters of Var-21 soya. The information obtained will serve as a basis for future research, especially into the effectiveness of organic fertilizers on other crop species, and under other agro-environmental conditions.
