Effect of partition foliar applications of organic, biochemical, and chemical fertilizers on some growth characteristics and yield of sorghum

Abstract

To determine the effect of partition different types of fertilizer (Acadian, Humus and Foliater) on some vegetative traits and seed yield of sorghum var. Inkath. Field experiment was carried out during spring and autumn 2017 in the experimental fields of crop science / college of agricultural engineering sciences, factorial experiment was applied according to RCBD design with three replications. The three types of fertilizers was the first factor and control treatment. The second factor was the partition of the spray into three ways (whole concentration for one spray, half concentration for two sprays and one third concentration for three sprays ) at seed initiation stage, beside control treatment (spray with distil water only). The results of the statistical analysis showed that there was a significant effect of the three fertilizers in the studied traits. The plants treated with Acadian gave the highest average leaf area, chlorophyll content, seed per head, grain weight, and plant yield when compared other treatments. The results also showed partition spray to three sprays was superior to other fertilizer treatments in most studied traits. The results indicates that spray with Acadian into three sprays was best treatment in this study.
