Twelve actinobacterial strains were isolated from tomato rhizospheric soil Manipur, a state in North East Indian Himalayan Region and screened for keratinolytic plant growth promoting traits. Nine promising isolates identified as Streptomyces species using partial 16S rRNA gene sequencing. Among the seven showing chicken feather degradation activity, three RCM-SSR-2, -6, -12 found to be most efficient degrading achieving 90% weight loss within 48 h of incubation. They also showed maximum...

Rapid postharvest physiological deterioration (PPD) in cassava ( Manihot esculenta Crantz) tuber is a significant concern during storage. The freshly harvested tubers start spoiling within 24 to 72 h. Accumulation of H 2 O one the earliest biochemical events that occurred PPD, which was detected using 3,3 diaminobenzidine (DAB) two contrast genotypes, MNP Local A (29–57 μg g –1 ) and Sree Prakash (64–141 ). Accumulating fluorescence hydroxycoumarin compounds emitted by observed under an...

To assess the irrigation strategies, an experiment was conducted with three wheat varieties viz. BARI Gom-19, Gom-21, and Gom-24 four levels of no (control), one at crown root initiation (CRI) stage [17 days after sowing (DAS)], two irrigations CRI (17 DAS) booting (52 DAS), heading (67 DAS). Variety, their association revealed notable impact on yield wheat. Within tested, demonstrated highest performance, producing greatest total tillers/hill (4.43), effective (3.75), grains/spike (40.55),...

Abstract The study was carried out with the main objective to prepare silage using leaves of Melocanna bacifera a dominantly available bamboo species in Mizoram. chemical composition and fermentation coefficient (FC) fresh were analyzed before preparation. DM content ( baccifera ) 40.38 g per 100 leaves. buffering capacity sample estimated 30.95 mE DM. A lower water soluble (WSC) (4.8%) makes it difficult for ensiling without additives. uniform spray molasses solution (4%) applied compacted...
