Chip bud technology is the most promising technique of sugarcane production, where chip bud seedlings raised in controlled environment are transplanted in main field. Generally, in this technology, seedlings are transplanted at a particular age, with a definite spacing and proper management practices. This technology is found to be beneficial in terms of growth, cane yield over conventional and other method of planting. However, depending upon the edaphic and climatic variation, researchers are working on evaluation of proper nursery management, spacing and other production technology of chip bud seedlings related to its growth, yield and economical return. In this article an attempt has been made to reveal some of the research finding srelated to this technology for further research with an objective to maximum the economical return by curtailing the cost of production.

Recent times highly demand an efficient and cost-effective alternative for keratin waste degradation. Studies have shown that microbial hydrolysis of keratin waste is a popular biotechnological substitute for the process of ker-atin waste valorization, which is achieved through the microbial keratinases. To sequester keratinolytic microorganisms with potential to influence com-mercial utilization as keratinase manufacturers, the present work evaluates the endophytic bacterial strains isolated from the host plant Capsicum chinense. Spectrophotometric analysis revealed that out of 4 isolated bacte-rial strains from the root and shoot parts of C. chinense, 1 strain showed sig-nificant caseinolytic and keratinolytic activities. The caseinase enzyme was measured spectrophotometrically and found to be 6.3 U/ml and the keratinase production was measured to be 93U/ml. Bacillus subtilis strain was used as a positive control. Molecular identification showed the efficient endophyte Cb4 to be Enterobacter sps, while the lesser efficient isolate Cb1 was identified as Proteus sps. The potential of the bacterial strains to dena-ture keratin substrates was assessed by SEM, FTIR spectra analysis. Bacterial endophytes isolated from the roots and shoots of C. chinense were tested for their economic importance to replace severe chemical approaches for remediating the environment. The results confirmed the amplified efficacy of the host plant, harboring the beneficial bacterial endophytes.
