ThesisItem Open Access Assessment of Morphological, Biochemical and Molecular Diversity in Zea mays L.(MPUAT, Udaipur, 2014) Sharma, R. S.; Joshi, ArunabhThe present investigation was carried out with 20 diverse genotypes of Maize (Zea mays L.) comprising hybrids, composites and land races for the assessment of genetic diversity through morphological, biochemical (Isozyme) and molecular (RAPD and ISSR) markers. The crop was raised during kharif, 2011 in randomized block design with three replications at Instructional Farm of Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur, India. Observations were recorded for all 11 characters including grain protein content. Data so obtained were subjected to analysis of variance, genotypic variability parameters, correlation, path coefficient analysis and genetic divergence analysis. For biochemical characterization enzymes were extracted from young leaves (28 DAS) to develop zymograms. Similarly for molecular analysis, DNA was isolated in seedling stage (21-25 DAS) and used as a template for PCR amplification using 16 RAPD and 10 ISSR primers. Analysis of variance revealed significant genetic variability among the genotypes for all the 11 characters including grain protein content. Test weight, grain yield per plant, grains per cob, grains per row and harvest index revealed high genetic gain along with high estimate of heritability and GCV indicating that selection could be practiced for improvement. Correlation coefficient revealed close association at genotypic and phenotypic level. Grain yield per plant was strongly correlated with days of 50% flowering, days of maturity, cob length, grains per cob, cob girth, grains per row and harvest index. Path coefficient analysis indicated that harvest index, biological yield and grains per row exhibited significant direct effect on seed yield in maize.ThesisItem Open Access Development of Low Cost Production Technology for Sustainable Productivity of Rice - Wheat Cropping System(jnkvv, jabalpur, 2002) Shrivastava, Deepak; Sharma, R.

S.A study was carried out to elucidate the effect of addition of antioxidant principles of onion skin via a preextract on the oxidative stability of ghee. A composite sample of onion skin obtained from local vegetable market contained 9.56 per cent moisture, 0.79 per cent fat, 0.56 per cent protein, 8.35 per cent ash and 80.74 per cent carbohydrates as major constituents. It also contained 3.17 per cent total phenolics, 0.41 per cent water extractable phenolics and 0.015 per cent phospholipids. Fresh ghee manufactured in a commercial dairy by creamery butter method employing prestratification and clarified at 110°C without' any holding period was used for the study. The antioxygenic compounds of onion skin were extracted into methanol, dried and ground to get a fine powder which was added to ghee at a rate of 0.5 per cent (w/v). The mixture was kept at 40 ± 2°C for 12 h and then at 50 ± 2°C for about 3 h followed by decantation of clear ghee, the pre-extract. This pre-extract was finally added to ghee at the rate of 0 (T0, control), 10 (T1), 15 (T2) and 20 (T3) per cent levels constituting different treatments. For comparison, the last treatment was addition of butylated hydroxy anisole (BHA) at the legally permitted rate of 0.02 per cent (T4) . To monitor the effectiveness of the additions, peroxide value of all ghee samples was determined immediately after receiving the ghee and after every 48 h interval of storage at 80 + 2°C in a memmert type oven. The pre-extract contained on an average 21.3 mg per cent water extractable phenolic compounds. The water extractable phenolics content of ghee samples added with the pre-extract at various levels were in order : 3.580 mg/100 g (T3) > 2.894 mg/100 g (T2) > 2.211 mg/100 g (T1) > 1.106 mg/100 g (T4) > 0.843 mg/100 g (T0). The antioxygenic indexes were in the order : 1.22 (T4) > 1.19 (T3) > 1.17 (T2 and T1) > 1.00 (T0). From the results of this study, it is concluded that the antioxygenic compounds of onion skin can be extracted in a crude form using methanol, dried and ground to obtain a fine powder. Addition of these antioxygenic compounds in the form of pre-extract enhanced the oxidative stability of ghee. Addition of such pre-extract at all the levels studied in this experiment (10, 15 and 20 per cent, v/v) was found to be almost at par with addition of BHA at 0.02 per cent level. The phenolics present in the onion skin appear to be the main contributory factors in enhancing the oxidative stability of ghee. Quercetin and anthocyanin, the phenolic compounds reported to be concentrated in the onion skin are expected to be the principal antioxidants. Besides these compounds, carotene, Vitamin C and phospholipids/ phosphorus containing compounds of onion skin could also be responsible for part of the antioxidant effect observed.ThesisItem Open Access Effect of planting geometries and age of seedlings on growth parameters, yield attributes and yields of the inbred and hybrid rice(JNKVV, Jabalpur, 2007) Parte, Archana; Sharma, R. S.ThesisItem Open Access EFFECT OF SODIUM AND POTASSIUM METABISULPHITES ON SHELF-LIFE OF KHOA(AAU, Anand, 1982) Patel, Keshavlal Hemrajdas; Sharma, R. S.An experiment was planned to assess the effect of addition of sodium and potassium metabisulphites on the shelf-life of khoa. Khoa was prepared from buffalo milk in a steam jacketed stainless steel kettle. The treatments imposed were control (no additive), addition of sodium metabisulphite (T1) and potassium metabisulphite (T2) each separately at the rate of 1000 ppm on the basis of milk used for preparation of khoa in a particular batch. The added sodium and potassium metabisulphites supplied respectively 673.9 and 576.3 ppm of sulphur dioxide. The samples of khoa were stored in plastic boxes of 21.5 cm x 11.5 cm x 11.5 cm size at room temperature (31°C). Khoa was filled in boxes upto three-fourth of their capacity and the lids were put on only when the samples attained normal temperature.ThesisItem Open Access Effect of tillage and sowing management on productivity and economics of rice-wheat cropping system and soil properties in vertisols(JNKVV, Jabalpur, 2006) Jha, Amit Kumar; Sharma, R.
