“…Determination of the severity of infection is used the scale of each disease according to ICRISAT (2007) in [15] which the disease scouring showed in Table 1-3 Large spots are located on the lower leaves, with very few in the middle. 3 Large spots are found on the lower and middle leaves but very severe on the lower leaves, and some of the lower leaves are defoliated. 4…”

“…is a food commodity other than rice and corn in Indonesia [1]. Sorghum has the potential to be developed in Indonesia because it adapts widely on sub-optimal land [2,3,4]. Sorghum has the advantage that it is more tolerant of abiotic stresses such as drought and acid soils than sugarcane and maize [5,3,6,4] and as well as of wet conditions.…”

The study aimed to obtain sorghum mutant lines from the Numbu variety resistant to 3 major diseases (leaf rust, leaf spot, and anthracnose). The research was conducted at the ICERI Experimental Garden. The treatments were arranged using a Randomized Block Design with 3 replications with materials tested were five mutant lines derived from a Numbu variety (lines MM-5, MB-3. MB-5. MM-3, MM-4) and resistant comparison varieties (Kawali and Numbu) and check susceptibility lines (Super 2 and line SRN48-1) as a comparison for each disease. The results showed that the five test genotypes had high resistance to 3 main sorghum diseases. The MB-3 and MB-5 mutant lines were resistant to leaf rust and leaf spot Cercospora, and moderately resistant to anthracnose. The lowest infection rate of leaf rust disease was in the MB-5 line, which was 0.0019. This illustrates the low development of rust disease in this line. While the other 3 strains (MM-3, MM-4, and MM-5) consistently reacted moderately resistant to the 2 main diseases of sorghum (rust and anthracnose).

Background: Seed quality, an important determinant of germination and vigor potential, can be improved through seed priming. This study was therefore aimed at assessing the effects of steeping duration and inoculum concentration on the germination and seedling growth of five seed crops through priming with growth-promoting rhizobacteria. Methods: Broth cultures of five bacterial strains, belonging to Providencia vermicola (2 strains), P. rettgeri (2 strains), and Bacillus cereus (1 strain), isolated from rhizosphere were used for priming in the study. Seeds of cowpea (Vigna unguiculata), soybean (Glycine max), sorghum (Sorghum bicolor), sesame (Sesamum indicum), and okra (Abelmoschus esculentus) were used as experimental materials. To determine the effects of steeping duration, viable seeds of the respective crops were primed with broth cultures of the respective isolates and allowed to stand for a known duration (1, 2, 3, 4, or 5 h). Then, another set of viable seeds was steeped in varying concentrations of the bacterial cultures for a period that was determined to be the optimal steeping duration in the first experiment. Result: At the expiration of both experiments, final germination, mean germination time, germination index, and vigor index of the respective seeds were estimated. Generally, higher final germination and seedling vigor index values were restricted to shorter steeping periods for cowpea and soybean. With respect to inoculum concentration, there was no consistent pattern with the parameters. Conclusion: The study revealed the primacy of steeping duration over inoculum concentration with respect to bacterial priming.
