Melia azedarach belongs to family Meliaceae. It is a deciduous tree, native to Indian sub-continent but now has spread in many Asian countries and also in different regions of the globe. It is an economically and medicinally important woody tree that is traditionally used for management of malaria, diabetes and skin diseases. It is highly valuable indigenous species. The main difficulty of establishing forest plantation of Melia azedarach species is its poor seed germination. Seed of Melia azedarach are hard and seed pre-treatments aim at breaking the physical barrier to enhance water absorption. The experiment consisted of 38 treatments in which various pre-sowing treatments were applied to the drupes such as normal water (24, 48 and 72 hrs), hot water (4, 6 and 8 min.), hot water with keeping drupe in same water for 24 hrs (4,6 and 8 min.), conc. H2SO4 (4, 6 and 8 min.), Gibberellic acid (200, 300 and 400 ppm for 24 hrs), cow dung slurry (2, 4 and 6 days) and these treatments were also given in combination with mycorrhizal fungi namely Glomus mosseae. Results revealed that the germination, growth, biomass and physiological parameters of pre-sowing treated drupes were significantly increased as compared to control, except for hot water treatment. The germination percentage (75.87) and other quality parameters such as mean daily germination, germination value and speed of germination were recorded highest in treatment with cow dung slurry for 6 days + Glomus mosseae followed by cow dung slurry for 6 days.
To stabilize the crop productivity in rainfed agriculture, it is necessary to characterize rainfall with respect to amount, distribution and its dependability which is an important parameter to evolve suitable cropping patterns. The present investigation has been done to study rainfall characteristics of Rakh Dhiansar (320 39’ N, 740 53’ E, 294 m amsl), Samba district of Jammu region using 30 years (1987-2016) daily rainfall data. In this study, weekly rainfall was worked out from daily values and used for initial, conditional and consecutive dry and wet spell analysis done by using Markov chain probability. The highest rainfall received during the month of August followed by July, September, June and March with the corresponding values of the total amount of rainfall are 321.6, 317.8, 146.6, 92.3 and 63.5 mm with coefficient of variations of 48.7, 41.3, 66.2, 85.0 and 129.2%, respectively. Maximum amount of rainfall was received through S-W monsoon i.e 878.6 mm which accounted for about 77.5% of the annual rainfall in kandi belt of Samba district. The probability of occurrence of wet week is more than 35% during 24 SMW (11-17 June), thus the pre monsoon rains can be utilized for summer ploughing and initial seed bed preparations for the sowing, better germination and good crop stand of kharif crops. It is concluded that there is a need of reconsidering the cropping pattern, selection of crops, their varieties and management practices for kandi belt of Samba district to minimize the risk in crop production as inflicted by rainfall variability.
Physicochemical and sensory characteristics of red and yellow banana pseudo stem flour biscuits were studied to standardize the banana pseudo stem flour supplement in the combine for preparing biscuits. The composite of wheat flour was replaced by banana pseudo stem flour at various percentage incorporation ranges in biscuit production. Nutritional properties of red and yellow banana stem flour incorporated biscuits showed significant difference (p<0.05). Bulk density, water activity and Color values exhibited higher as a result of yellow banana stem flour. Physical properties of biscuits substituted with 30% of banana stem flours were observed significantly higher (p ≤ 0.05) value. Proximate analysis results showed higher fibre content in red banana flour biscuits than yellow banana biscuits. Water activity, hardness and colour of the developed biscuits were showing significant difference than control. Sensory attributes indicated that the yellow banana stem flour biscuits had the higher acceptability. Hence, banana stem flour proved acceptable not only in quality characteristics but also fulfills the demand of dietary fibre and is very palatable to ingest and will be one of the agreeable biscuit taste with improved nutritional properties
In this paper, the results of an optimization study to calculate the optimal partial gear ratios of three-stage bevel helical gearboxes are presented. The objective of the study was to achieve the minimum gearbox bottom area. To implement it, a simulation experiment was conducted. In the experiment, the influence of eight main design parameters including the total gearbox ratio, the coefficients of wheel face width of three stages, the allowable contact stresses of all stages, and the output torque to the optimal transmission ratios of the analyzed gearbox. In addition, regression formulas determining the optimal gear ratios of the second stage u2 and the third stage u3 components have been given.
This study mentions the problem of calculating optimal gear ratio according to the objective function minimal gearbox bottom area. A review of an approach to the optimization of gear ratio is conducted. By using the Design of Experiment technique combined with the Minitab®19 software, we studied the impacts of the design variables on the optimal transmission ratio u2. The results received indicated that the input variables, as well as their interactions, have an important influence on the response u2. Finally, a useful regression model is proposed based on the experiment data and its reliability is confirmed through the results obtained.
