Abstract: Today microbial lipase occupies a position of distinction amongst biocatalysts due to their capability to catalyze a broad range of reactions in water and non water media. In view of the enormous applications of lipases in the industries, lipase produced by Cunninghamella sp. in submerged fermentation was partially characterize to determine its suitability in industries. High level of activity of Cunninghamella lipase was found at 37 ºC and pH 9.0. Stability of lipase was superior within the temperature range of 28 ºC to 50 ºC and pH 4 to 10. Significant activity at pH 9 to 10 and stability at temperature 50 ºC indicates alkaline and thermostable nature of lipase which would determine its use in detergent industries. Among the organic solvents (10% v/v), acetone was found excellent inducer of lipase activity. Monovalent cations (K+ and Na+) and divalent Ca2+ showed stimulatory effect on lipase activity whereas Mn2+ comparatively declined lipase activity.

Abstract:  The Present investigation was conducted during summer-rainy season, 2013 at Vegetable Research Block of Uttarakhand University of Horticulture and Forestry, Ranichauri Campus, Tehri-Garhwal in polyhouse equipped with thermo censored exhaust fans and drip irrigation system. The experiment was laid out in two factors RBD with five replications. The treatments in first factor included two methods of application of NPK viz., soil dressing ( A1) and drip fertigation (A2) whereas second factor included four nutrient packages viz., N:P:K @ 160:80:40 kg/ha + FYM @ 20 t/ha (F1), N: P: K @ 160:80:40 kg/ha + FYM @ 20 t/ha + lime @ 3.0 q/ha + PSB + Azotobacter (F2), Observations were recorded on plant growth and fruit yield characteristics viz. number of fruits per plant, fruit yield per plant (g), The results indicated that the drip fertigation of NPK (A2) appeared to be the most promising treatment in polyhouse grown capsicum for fruit yield (per plant as well as per m2) (870.0 g and (6.80 kg, respectively), number of fruits per plant (31.31), intervals starting from 45 days after transplanting would result in 990.0 g fruits per plant or 7.71 kg/m2 area or 77.0 q/ha in temperate hills of Uttarakhand.

Abstract:  Potato tubers of variety Kufri Jyoti and Atlantic (35 – 45 mm size) was taken as planting material. The effect of various seed treatment (Urea, Thio-urea and KMB) was examined by treated the seeds before planting. the observations of the study was number of stem per plant, number of tuber per plant and total yield, the haulm was killed at 75 days after planting and the data for number of tuber/plant and total yield were taken at 25 days after haulm killing at harvesting. It is observed that the seed treatment by urea at 5 % found most suitable concentration to increase the total yield of potato crop variety Kufri Jyoti in comparison to all other concentrations i.e. 1, 10, 15 % and in comparison to control also, but to establish the fact, the study must have recommended for further investigation in future. 1% thio-urea is also found most suitable concentration for early emergence, higher number of tuber per plant and highest yield of potato crop. It is also observed that with the increases in thio-urea concentration more than 1%, days taken for emergence as well as yield is also decreases. Seed treatment by KMB at 5 % also found most suitable concentration to increase the total yield of potato crop variety Kufri Jyoti in comparison to all other concentrations i.e. 1, 3, 7 % and in comparison to control also.

Abstract:  The present investigation was carried out at the Research Block, Department of Crop Improvement, VCSG Uttarakhand University of Horticulture and Forestry, College of Forestry, Ranichauri, Tehri Garhwal, Uttarakhand. The experimental material comprised of 73 diverse faba bean genotypes. The crop of different genotypes was raised in an augmented design. Analysis of variance revealed among the checks were significant for six characters viz., significant for days to maturity, field emergence, plant height (cm), number of pods per plant, pod length (cm) and seed yield per plant (g). The correlation revealed that seed yield per plant showed positive correlation with pod length, while days to maturity exhibited highly significant and positive correlation with days to 50% flowering, number of pods per plant showed significant positive correlation with field emergence and highly significant and positive correlation with plant height, number of seeds per pod showed significant and positive correlation with plant height and 100 seed weight also showed highly significant and positive correlation with number of pods per plant. The results of path coefficient analysis using simple correlation coefficient showed that highest positive direct contribution towards seed yield per plant was exhibited by pod length followed by number of pods per plant and days to maturity.

Abstract:  The experiment was laid out in a Factorial Completly Randomized Design (FCRD) with three replications and 5 treatments namely; T(bael leaves extract @ 15%), T(bael leaves extract @ 25%), T(turmeric powder @ 15%), T4  (turmeric powder @ 25%), and T­5 (control). After harvesting of fruits were treated with different botanical extracts treatments and stored in room temperature from 0 days to 120 days and physico-chemical analysis was done at an interval of 30 days viz., initial day, 30 days of storage, 60 days of storage, 90 days of storage and 120 days of storage. The present investigation clearly revealed that post harvest treatments of apple fruits with different botanical extracts was effective in increasing the shelf life of fruit as it helps in decreasing the PLW and rotting percentage of fruits and also helps in increasing the physico-chemical characteristics of the fruits. Among the treatments highest (7.36%) PLW and decay rotting (45.55%) was observed in T5 (control) and lowest (3.09%) PLW was recorded in T(bael leaves extracts @ 15%). After 120 days of storage maximum total sugar (11.76%) were observed in T(turmeric leaves extract @ 15%) and maximum reducing sugar (9.90) was found in T5 treatment (control)  was at par with the treatments having lowest physiological loss in weight, rotting percent and highest total sugars.
