Effect of liquid organic fertilizer on growth and yield of maize

Abstract

This study investigated the effect of liquid organic fertilizer (LOF) application on growth and yield of maize var. Seeds Tech 188. The experimental design was arranged in completely randomized design (CRD) with 3 replications and 8 treatments. The results showed that the application of LOF of 1,200 L/rai in combination with chemical fertilizers containing all major elements equivalent to 1,200 L/rai of the LOF provided the highest of plant height, leaf greenness (SPAD reading), ear weight, ear without husk weight, grain weight, 100 grain weight and total N in grain which were not significantly difference from the applications of chemical fertilizers containing all major elements equivalent to 2,400 L/rai of the LOF and the application of LOF of 2,400 L/rai. Furthermore, the application of LOF of 1,200 L/rai in combination with chemical fertilizers containing all major elements equivalent to 1,200 L/rai of the LOF gave the highest of protein content in grain, followed by the applications of chemical fertilizers containing all major elements equivalent to 2,400 L/rai of the LOF and the application of LOF of 2,400 L/rai, respectively
