    BIOCHEMICAL PROFILING OF POTENTIAL GENOTYPES OF NORTH-WEST HIMALAYAN CEREALS, PULSES AND OILSEEDS
    (CSKHPKV, Palampur, 2018-09) Banta, Neha; Mohini, Kamal
    The mature seeds of four potentially superior genotypes/varieties each of the nine selected crops viz. barley, oats, wheat (cereals); linseed, sesame, soybean (oilseeds) and kidney bean, horsegram, moth bean (pulses) were evaluated for relevant biochemical constituents by following standard procedures. Significant statistical differences were observed for the biochemical constituents in the four genotypes each of all crops and the three crops of each group. Differences among the three groups were also apparent. The results from this study were utilized for carrying out the cumulative grading based on desirable quality parameters for identifying the best genotype in each crop i.e. Dolma/ VLB-118 in barley, TP-40 in oats, Saptdhara in wheat, Himani in linseed, Nurpur in sesame, Hara Soya in soybean, Mandi in horsegram, Kanchan in kidney bean and Jadia in moth bean. Highest protein content was observed in soybean (36.10%), followed by kidney bean (26.18 %), moth bean (21.51%) and the lowest was seen in barley (10.20%). However the protein digestibility of oats (75.87%) was found to be the best followed by wheat (72.77%), kidney bean (72.17%) and lowest was seen in sesame (56.52%). Linseed exhibited the highest fat content (48.86%) followed by sesame (47.96%) and soybean (20.59%) whereas minimum was observed in horsegram (1.76%). Highest carbohydrate content was seen in wheat (71.57%) followed by barley (69.47%), moth bean (60.73%) and the lowest was seen in sesame (14.62%). Potassium and calcium content was high in soybean (963, 392 mg/100g), horsegram (962, 296 mg/100g) and kidney bean (815, 298 mg/100g). For the trace element iron the best source was sesame (12.80 mg/100g) and moth bean (10.84 mg/100g). In the oilseeds UFA content was found to be more than twice the SFA content. Soybean was the richest source of essential ω-6 linoleic acid (51.87%) and linseed of ω-3 linolenic acid (53.57%). Sesame had the highest content of oleic acid (40.64%) and also a good amount of linoleic acid (44.41%). The lysine content was quite low in cereals (0.51%) in comparison to the pulses (8.95%) whereas an opposite trend was observed for the methionine content in cereals (1.7%) and pulses (0.46%). However a low content of both these amino acids was observed in the oilseeds linseed and sesame while soybean was poor in methionine (0.48%) and high in lysine (8.08%). The potentially superior genotypes/varieties thus identified can be used for further developmental research by the plant breeders and cultivation on a large scale by the farmers of H.P and others. The information regarding the identification of best crop for nutritionally important individual quality parameter will prove highly beneficial for the consumers.

    FATE OF BISPYRIBAC SODIUM IN SOIL AND ITS EFFECT ON RICE QUALITY
    (CSKHPKV, Palampur, 2018-07-24) Devi, Sureshna; Sharma, Neelam
    In present investigation entitled “Fate of bispyribac sodium in soil and its effect on rice quality”, a field experiment consisting of four treatments viz. bispyribac sodium 10g/ha, 20g/ha, 40g/ha and control was laid out in randomized block design (RBD) in the Department of Agronomy, Forages and Grassland Management, CSK HPKV, Palampur during kharif 2017. For residue and biochemical studies, soil and rice plant samples were collected at different time intervals after herbicide application and rice grain samples at crop harvest. Bispyribac sodium at three application rates i.e. 10g/ha, 20g/ha and 40g/ha persisted in soil upto 10, 15 and 45 days after herbicide spray, respectively. The degradation data generated indicated that more than 75 per cent of applied bispyribac sodium dissipated within 7 days of herbicide application. The logarithmic plots of herbicide concentration of different doses vs time fitted first order kinetics decay curve. Terminal residues of bispyribac sodium in rice grain were below detectable level (≤0.025μg/g). A significant decrease over control in biochemical attributes of rice leaves i.e. ALS activity and total carotenoids was observed upto 10 and 30 days respectively after bispyribac sodium application and thereafter the ALS activity and total carotenoids values were not influenced conspicuously. Whereas, total chlorophyll and total sugar content in rice leaves increased significantly with maximum increase noticed in treatment bispyribac sodium 20g/ha. Quality parameters i.e. total protein, total sugars and starch content were not influenced very distinctively with applied bispyribac sodium treatments. The data on residues and biochemical studies of bispyribac sodium in rice suggest that use of bispyribac sodium at three rates of application in rice crop is safe both in terms of crop quality and food safety point view. It can also be inferred from the above findings that effect of bispyribac on ALS and total carotenoids was temporary and recovered with passage of time.

    ANTIOXIDANT PROPERTIES AND MOLECULAR DIVERSITY OF MEETHI NEEM (MURRAYA KOENIGII (L.) SPRENG)
    (CSKHPKV, Palampur, 2018-02-09) Reetu; Singh, Nageswer
    Fifteen wild Meethi Neem leaf samples collected at three stages viz. pre-flowering, flowering and fruiting stages from different locations of Kangra and Mandi district of Himachal Pradesh were analyzed to evaluate phytochemical constituents and to identify the genetic diversity. The range of variation for phytochemical constituents at three stages varied significantly viz. total chlorophyll (0.79 to 1.43, 1.31 to 1.94 and 0.88 to 1.10 mg/g), total carotenoids (30.55 to 49.25, 49.09 to 60.81 and 31.24 to 41.42 μg/g), ascorbic acid (7.01 to 9.82, 3.58 to 6.06 and 2.99 to 4.93 mg/100g), total phenol (170 to 304, 266 to 450 and 213 to 364 mg/g), simple phenol (93 to 163, 150 to 243 and 123 to 220 mg/g), tannins (76 to 143, 116 to 207 and 47 to 156 mg/g), flavonoids (15.17 to 33.40, 25.16 to 58.17 and 17.54 to 37.34 mg/g), polyphenol oxidase (0.030 to 0.058, 0.017 to 0.031 and 0.007 to 0.021 ΔOD/minute), antioxidant activity (4.01 to 7.42, 8.08 to 13.60 and 3.11 to 6.37 μg/ml), essential oil (0.64 to 0.89, 0.85 to 1.00 and 0.54 to 0.70 per cent) and quinones (2.05 to 2.97, 3.07 to 4.95 and 1.02 to 1.96 mM/min/g tissue). All parameters showed highest value at flowering stage except ascorbic acid and polyphenol oxidase activity. Clustering analysis with respect to biochemical constituents revealed that the geographically distinct collections of Meethi Neem were clustered together. For molecular characterization by ISSR, a total of 120 highly reproducible bands were obtained out of which 74 were polymorphic. The polymorphism ranged from 12.5 to 100 per cent. Dendrogram generated using UPGMA separated 10 collections into 2 major clusters with 46 to 100 per cent similarity. The overall analysis revealed that Meethi Neem collections from the same geographical location were genetically and biochemically diverse.

    QUALITY ASSESSMENT OF UNDERGROUND DRINKING WATER SOURCES OF AGRICULTURE UNIVERSITY PALAMPUR, HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2018-07) Meenakshi; Chauhan, Ramesh C.
    The present investigation was carried out to assess the underground drinking water quality of Agriculture University Palampur, Himachal Pradesh. The physico-chemical characteristics such as temperature, pH, turbidity, conductivity, total solids, total suspended solids, total dissolved solids, alkalinity-P, alkalinity-M, total alkalinity, calcium, magnesium, chloride, fluoride, iron, total nitrate-nitrogen, total phosphate-phosphorous and microbiological characteristics like total coliform were estimated and recorded at four different study sites seasonally from July-2017 to June- 2018. The majority of physico-chemical characteristics showed significant relationships among themselves. The quality parameters i.e. temperature, pH, turbidity, conductivity, total solids, total suspended , total dissolved solids, total alkalinity, calcium, magnesium, chloride, fluoride, total nitrate-nitrogen, phosphate-phosphorous and microbiological characteristics like total coliform were found much below the desirable limit except for iron as per BIS. The iron concentration during study was recorded maximum (1.54 mg/L) in the summer season and minimum (1.4 mg/L) in rainy season which is beyond the permissible limit as per BIS. Although iron has got little concern as a health hazard but is still considered as a nuisance in excessive quantities. The limits of iron in waters are based on aesthetic and taste consideration rather than its physiological effects. Microbiologically also all of the water samples were found free of MPN bacteria. It can, therefore, be concluded that the underground water of university is of very good quality and suitable for drinking purposes
