    Evaluation of sugarcane varieties for quality jaggery production
    (CCSHAU, Hisar, 2020) Shweta; Kanika, Pawar
    The present investigation entitled ―Evaluation of sugarcane varieties for quality jaggery production‖ was carried out with the objectives to evaluate the sugarcane varieties for producing jaggery and to study the quality and nutritional value of the jaggery. The sugarcane varieties namely CoH 160, Co 238, Co 89003 (Early varieties), CoH 119, CoH 167 (Mid varieties) were harvested at November, January and March months and examined for quality jaggery production. The extracted juice of all the five sugarcane varieties was analyzed for its quantitative characteristics. The data showed that the juice extraction percent of different sugarcane varieties ranged from 48% (CoH 167) to 55.7% (CoH 119) and the jaggery recovery percentage ranged from 17.2 (CoH 119) to 19.9 (CoH 160) among all three harvesting months. There was non-significant difference observed in the TSS, pol percent, purity percent and ccs percent in different sugarcane varieties in all the three months. The jaggeries were nutritionally, physico– chemically and microbiologically analyzed. Jaggery samples were vacuum packaged with polyester polythene packaging material and stored at room temperature for 60 days. The data showed there was non- significant difference observed in sucrose percent, net rendement value, mineral content and proximate composition of the jaggery prepared from different sugarcane varieties in the month of November. In the month of January, there was non-significant difference observed in iron, calcium and proximate composition of the jaggery. In contrast significant difference was observed in the zinc content of the jaggery. In the month of March, there was non-significant difference observed in reducing sugar, total sugar, sucrose percent, net rendement value of the jaggery. According to sensory evaluation, Co 89003 followed by CoH 160 was observed maximum and statistically different from all the other varieties. Storage studies were done with two best varieties (CoH 160 & Co 89003) up to 60 days in the month of January. Significantly decreased in moisture content, total sugars, non-reducing sugars was observed with the increased storage period. But the reducing sugar of variety CoH 160 increased significantly and the other variety Co 89003 decrease significantly with the advancement of storage period. There was no microbial load was observed in jaggery stored for the period of two month.

    Study on sustainability and survival rate of in–vitro propagated sugarcane under green house conditions
    (CCSHAU, Hisar, 2021-09) Shweta; Tallapragada, Sridevi
    The investigation was carried out to study the effect of different energy sources and gelling agents on in vitro multiplication and rooting response on sugarcane cultivar Co-89003. For in vitro multiplication plant cultures were inoculated on MS media supplemented with various sugars (fructose, sucrose, glucose, table sugar and maltose) and gelling agents (agar-agar, agarose, gelrite, guargum and isabgol). The maximum shoots (11.5±0.23 and 9.7±0.23) were observed on medium enriched with table sugar and agrose, respectively. And the maximum shoot-length (7.1±0.39 cm and 7.1±0.51cm) was noticed in sucrose and agar –agar media on after 28th day of inoculation. The very good growth/ rooting (+++++) was observed on ½ MS media supplemented with sucrose and gelrite. Then well rooting plantlets were transplanted into pots containing various compositions of soil, sand, vermicompost, FYM, coco pit and perlite for acclimatization. The maximum and survival (100%) were observed in four different potting mix including sand : soil : FYM, Sand : Soil : Vermicompost, Sand : Soil : FYM : Vermicompost and Coco pit : Vermicompost : Perlite under green house conditions. Hardened plantlets were successfully transferred to the field conditions

    Effect of heavy metaltoxicity on biomolecules and antioxidative enzymes in earthworm, Eisenia fetida
    (CCSHAU, Hisar, 2020-06) Shweta; Gupta, R.K.
    Earthworms are most easily obtained and one of the largest component of the soil biota and these organisms are very suitable for estimating disturbance to soil ecosystems. The worms have the ability to increase the availability of nutrients to plants due to the presence and activity of micro flora in their gut. Many activities of human beings such as waste disposal and land treatment etc. have led to increase in amount of metals in soil ecosystems. These metals not only kill target species, but prove harmful to non-target organisms like earthworms and due to this reason; the present study was carried out to investigate the effect of heavy metals on biomolecules and antioxidative enzymes of earthwormE. fetida. The maximum reduction in biomolecules i.e. 17.80% in crude protein, 33.37% in total tissue carbohydrate and 37.59% in crude lipid was seen in earthworms treated with Cu + Sn (0.05 +0.05 ppm). There was a significant increase in the activity of antioxidative enzymes i.e. SOD, 23.65% and 31.77% and POD 44.44% and 28.57% in worms exposed to Cu (1.00 ppm) and Cu+Sn (0.05+0.05 ppm), respectively. Thus the study proves that copper is toxic to earthworms as compared to tin.The maximum ethanol production i.e. 5.30% was observed with 0.50% earthworm cast as compare to control in which no cast was used and ethanol production was found to be 0.83%. After the observation it can be concluded that earthworm cast, is also a rich source of nitrogen and phosphorous, may be considered as alternative of chemical fertilizers like urea and disodium hydrogen phosphate, required for the growth of yeast during fermentation.
