Abstract

This study investigated the biomass productivity of sorghum main crop, first ratoon, and second ratoon. A randomized complete block design was employed for the main crop experiment, with eight sorghum genotypes (NS2-19, NS2-102, NS2-109, NS2-111, NS2-140, IPB 4, IPB 8, and “Numbu”) as the treatment factor. The ratoon crop was designed using a Split Plots Design with two treatment factors and three replications. The first factor was fertilizer treatment on the ratoon crops, with two levels: complete N, P, and K fertilizer (urea 133 kg.ha-1, KCl 100 kg.ha-1, and SP-36 100 kg.ha-1) and N fertilizer only (urea 133 kg.ha-1); this factor was arranged as the main plot. The second factor comprised eight elite sorghum lines, the same as those used in the main crop experiment, arranged as subplots. The results indicated that complete NPK fertilization and N fertilizer alone produced similar biomass productivity in sorghum ratoon crops. Among the genotypes, NS2-140 demonstrated the highest biomass productivity in the main crop, NS2-109 in the first ratoon, and NS2-19 in the second ratoon. The second ratoon exhibited the highest biomass yield compared to the main crop and the first ratoon.

Abstract

Indonesian sorghum (Sorghum bicolor L.) germplasm with the highest genetic diversity can serve as a valuable resource for developing high-yielding cultivars. Therefore, the present research aimed to obtain information on genetic variability in the population and also determine the key traits associated with grain yield using correlation and path analysis in sorghum F2 population. The sorghum parental genotypes 'Demak 4' and 'Soraya 3', and a local high yielding IPB line, NS 19, NS 109, and NS 111, were used in the crosses. The F2 population was evaluated against parental cultivars and four check genotypes. The results showed that 64 individual plants were observed as transgressive segregants. Meanwhile, the number of leaves and plant height were controlled polygenically through additive genes. The traits of panicle diameter, dry panicle weight, and grain weight per panicle possessed the highest genotypic coefficient of variance. The traits dry panicle weight and diameter were significantly positively correlated with grain yield. The considerable positive correlation with dried panicle weight, panicle length, and diameter could be used as selection criteria. The path analysis reported that the observed agronomic traits explained 97.07% of the total variation in grain weight per panicle.
