M., MADHU; SINHA, D. K.; GOWDA, HARISH; HARIPRIYA, SIRIPURAM; KUMARI, TULIKA Abstract: The present study evaluates the costs and returns associated with mulberry silk production. Primary data were collected through personal interviews with 90 sericulture farmers from six randomly selected villages and 35 silk reelers from two taluks. The analysis reveals that the total establishment cost for mulberry cultivation amounts to₹ 50,222.76 per acre, while the annual maintenance cost is₹ 28,568.73 per acre. The overall cost of producing mulberry cocoons per batch is estimated at₹ 44,234.86. Annually, the production cost of raw mulberry silk for six reeling basins totals₹ 1, 45, 76,798.40. Gross returns from the sale of the main product and by-products of silk reeling amount to₹ 1, 60, 46,945.76 per year, resulting in a net return of₹ 14, 70,147.36. This study highlights the profitability and economic viability of mulberry silk production, suggesting that while the initial and maintenance costs are significant, the industry remains profitable with a positive net return. The findings provide valuable insights for stakeholders in the sericulture sector, including farmers and policymakers, to make informed decisions regarding investment and management in silk production. Additionally, the study highlights the importance of efficient cost management and market strategies to enhance profitability in the mulberry silk industry.

The major breakthrough in the productivity of rice resulted in green revolution which may be regarded as the threshold line for the advancement in rice cultivation. The development of technologies in the area of breeding, biotechnology and sequencing is the major driving force for boosting the rice production. The content of this chapter presents the glimpses of development of improved rice varieties through the intervention of biotechnological approaches such as genome sequencing, molecular marker technologies, etc. The varietal development through rice breeding programme involves pure line selections and hybrid rice technologies. The biotechnological approaches, DNA marker technologies, genome sequencing and genetic engineering, improve the rice breeding at parent selection, trait mapping and their introgression at early stages, thereby reducing the time, labour and cost of development of improved varieties with high precision. The involvement of marker technologies leads to the development of an area of marker-assisted breeding, marker-assisted backcross programme, marker-assisted gene pyramiding and marker-assisted recurrent selection. The genome sequencing increases the density of DNA markers at base level such as SNP improving the genotyping of mass population through chip and array type platform, genomic selection, association mapping and allele mining. The major genomic sites have been mapped for qualitative traits, viz., biotic and abiotic stress tolerances, nutritional improvement, and the quantitative traits such as yield-related traits like blast resistance, bacterial leaf blight resistance, gall midge resistance, salt tolerance, submergence tolerance, drought tolerance, high Fe and Zn content, dwarf stature, etc. Sat, 01 Oct 2022 00:00:00 GMT http://irrpcau.inflibnet.ac.in:8080/jspui/handle/123456789/666 2022-10-01T00:00:00Z http://irrpcau.inflibnet.ac.in:8080/jspui/handle/123456789/665 Title: Introduction of Novel Biochip Technology in Seed Science Authors: NANDI, ASIT; SINGH, SUMEET KUMAR; KUMARI, SARITA Abstract: Novel technologies come with novel innovations. Biochips are small microprocessor, which can track desirable characteristics of materials under investigation. Introduction of biochip in seed science will provide huge avenue for agriculture in terms of profit, yield or satisfaction. A technology becomes fruitful when it satisfies human wants, enhance livelihood of the country. Biochip-seed integration at specific situations may enhance the productivity. Biochip technology along with satellite, software integration provides huge number of data through tracking biochemical reactions. Major advantages like tracking of biochemical and physiological changes in seeds under storage or in germination. Beside this many challenges also like complexity of technology, lack of technical personnel and heavy initial investment are also linked with commercialization of technology. Therefore, public-private partnership investment in research and development section, training of personnel and creating awareness among people especially farmers may make this technology practicable in near future.

Once seed is a precious resource for rehabilitation of nature for crop production in agricultural, horticultural, forest crop etc. But nowadays various issues are arising; some of it for a long period; its long-lasting effect providing worst result in present time, in near future too. Among all issues ‘Climate Change or Climate Alteration’is very big issue which was the biggest reason for less production in many crops for last two decade. Even NASA study finds drastic decreases in Corn yields in several continents by 2030.(Global Climate Change NEWS, 2021). One another study revealed that Maize, Soybean, Wheat, Rice which give us two-third caloric contribution of our body are gradually reduced by 7.4%, 3.1%, 6%, 3.2% respectively (Zhao et al., 2017). This kind of shocking result will give fearsome consequence in upcoming three-four decade or by 2060. Seeds of crops are cannot survive in the changing environment after sowing in field. If crops survived also they are providing very less yield. In case of some crop production decreases with line sowing with this warm environ; even a farmer apply broadcasting method (eg-Rice) then too reduced crop growth (low tillering as well as lower than average height) results into low yield due to huge competition for inputs and changing climate change. That’s the transition time to shift the technique as climate smart farming through synseed. A new innovation came in seed world is Synthetic seed or shortly Synseed. Synseed is encapsulated seed of plant tissue (embryonic and non-embryonic) like somatic embryos, shoot buds, root tissue etc. Synseed is effective in many cases. In many crops natural seed storage is a big problem due to proper technical facility, but synseed can replace this issue where synseed do not need any storage facility of proper temperature, relative humidity, moisture percentage (%). No chance of seed dormancy which is opposite to natural seed but this is also manage by synseed. Genetic variation is another issue that is very difficult to maintain in case of natural seed but synseed replace this disadvantage too. Another thing is chances of seed borne pathogen and disease is also minimized in case of synseed. If pathogen not acts as internal or external seed borne pathogen then chances of seed borne infect is also minimized as well as huge intake of pesticides also minimized by farmers. Synseed is evolved in less crop species till now. Possibilities of synseed in novel crops are very high. In new forest crops like Saw palmetto (Serenoa repens), Pacific yew (Taxus brevifolia), Goldenseal (Hydrastis cnadensis) having high chances of possibility.
