To study the effect of species varieties and number of seedlings per hill on the growth and yield of agronomical plants, a field experiment was conducted on glutinous rice (Oryza sativa L. glutinous). The experiment also investigated the efficiency of solar energy utilization. The treatment consisted of four glutinous varieties (Lusi, Grendel, Malang, and Gajih), and three levels of seedling per hill (1 seedling, 3 seedlings, and 5 seedlings). These treatment combinations were arranged in a split-plot randomized block design with three replications, and the difference in varieties as the main plot, while the number of seedlings per hill as the subplot. The measurement was done for leaf area, yield, and solar energy utilization. The study concluded that varieties of glutinous rice used in this experiment had a significant influence on the yield component, grain yield, the Efficiency Absorbed Energy (EAE) and the Energy Conversion Efficiency (ECE). The number of seedlings per hill did not give a significant effect on the number of productive tillers and grain yield. The highest yield achieved by Malang variety (7.81 t.ha-1) with ECE of 3.89 %. © 2018 ISISnet: Innovative Scientific Information Services Network. All rights reserved.
