Effect of Irrigation and Potash Levels on Keeping Quality of Potato

Irrigation and fertilizer are the most dominating factors, in deciding the keeping quality of potato. It is, therefore, essential to formulate the efficient, reliable and economically viable irrigation management strategy with the use of potassium nutrient in order to produce better keeping quality. The investigation comprising four levels of irrigation (25, 30, 35 and 40 mm CPE (Cumulative pan evaporation) and four levels of potash (0, 100, 125 and 150 kg/ha) was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, (Haryana) Hisar, India during two years to find out the optimum level of irrigation and potash for obtaining higher yield of potatoes with better keeping quality at ambient room temperature. The potato variety used for the investigation was Kufri Bahar. The treatments were laid out in a split plot design with three replications. The increasing levels of irrigation and potash showed significant improvement in keeping quality parameters of potato. Likewise, the values for physiological loss in weight and decay loss of potato tubers (%) at 15, 30, 45 and 60 days after harvest were the lowest with irrigation level 40 mm CPE and application of potash @ 150 kg/ha. The two years results suggest that the irrigation level 40 mm CPE along with potash @ 150 kg/ha has shown the best treatment combination for the storage of potato at ambient room temperature under semiarid conditions of Hisar (Haryana)

Increasing Throughput by Efficient Target Localization in WSN

The assumptions made for target localization in wireless sensor network is not up to date. Restricted equipment assets, vitality protection and clamor disturbance because of remote channel dispute and instrumentation commotion make new limitations on originators these days. In the proposed paper target localization system which is based on TDOA is discussed. At the point when an event is identified, every sensor having a place with a gathering computes an estimation of the objective's area. A MAC convention for remote sensor systems i.e. Occasion Based –Medium Access Control (EB-MAC) is produced, which is adjusted for occasion based frameworks that portrays target confinement frameworks. Besides, EB-MAC gave a dependable correspondence stage where high channel conflict was brought down while keeping up high throughpu

Classical and Bayesian estimation of stress-strength reliability of a component having multiple states

PurposeThis article presents the multi-state stress-strength reliability computation of a component having three states namely, working, deteriorating and failed state.Design/methodology/approachThe probabilistic approach is used to obtain the reliability expression by considering the difference between the values of stress and strength of a component, say, for example, the stress (load) and strength of a power generating unit is in terms of megawatt. The range of values taken by the difference variable determines the various states of the component. The method of maximum likelihood and Bayesian estimation is used to obtain the estimators of the parameters and system reliability.FindingsThe maximum likelihood and Bayesian estimates of the reliability approach the actual reliability for increasing sample size.Originality/valueObtained a new expression for the multi-state stress-strength reliability of a component and the findings are positively supported by presenting the general trend of estimated values of reliability approaching the actual value of reliability.</jats:sec

Isolated cutaneous leishmaniasis over face – A diagnostic dilemma

Cutaneous Leishmaniasis (CL) is a disease caused by an intracellular protozoa belong to the genus Leishmania, transmitted by the bite of a sandfly. It has diverse clinical presentation and may create a public health problem in endemic countries. CL is often confused with lepromatous leprosy, pimples and fungal dermatitis. This case is an isolated cutaneous variety in facial region which was mistaken and treated initially for fungal dermatitis and then for leprosy by local physicians. Smears examined from the skin lesion confirmed Leishmania amastigotes. The isolated localized CL may create confusion and its many differential diagnoses made delaying in the diagnosis

Comparative evaluation of different reference evapotranspiration models

The study was carried out to select best alternative method for the estimation of reference evapotranspi-ration (ET0). Accurate estimation of potential evapotranspiration is a necessary step in water resource management. Recently, the FAO-56 version of Penman-Monteith equation has been established as a standard for calculating ref-erence evapotranspiration (ET0) which requires measurement of a number of meteorological parameters namely, air temperature, relative humidity, solar radiation, and wind speed which may not be available in most of the meteoro-logical stations. Still there are different approaches (requiring less data) which estimate ET0 closely to Penman- Monteith (P-M) method for different climatological conditions. The present study is based on analysis of long term of 13 years (2000 to 2012) climatic data to calculate monthly reference evapotranspiration for Capsicum production (September–March) and also to compare the performance of evapotranspiration equations for Jhalawar district of Rajasthan with the standard FAO-56 Penman-Monteith method on the basis of the least root mean square error (RMSE) analysis. Hargreaves method and Pan evaporation (E-Pan) method overestimated the values of ETo when compared with FAO-56 Penman-Monteith method. On the basis of lowest value of RMSE, Pan evaporation method is found best alternative method to FAO-56 Penman-Monteith method in the study area

Effects of Postharvest Chemical Preservatives on Shelf Life of Tomato (Lycopersicon esculentum cv. Srijana)

In recent years, the practice of increasing the shelf life of post-harvest crops is gaining attention worldwide due to the failure of proper techniques to increase post-harvest shelf life. Tomatoes are fragile and have a low shelf life. It fetches low market prices during on-season production and fetches high market prices during off-season production. To address this scenario, research was conducted to study the effect of different preservatives on various physiochemical attributes of tomato (Lycopersicum esculentum). The effects of preservatives were studied on shelf life, disease infestation days, total soluble solids (TSS), titratable acidity (TA), pH, and weight loss percentage (WLP) at 2-day intervals during the storage period. The 7 treatments used were 2% CaCl2, 4%, CaCl2, 1% GA3, 3% GA3, 1000 ppm sodium benzoate, 2000 ppm sodium benzoate, and control in distilled water with 3 replications each. Each replication was immersed in a chemical preservative for 20 minutes and kept in a polyethylene bag. Among the treatments, fruits treated with 3% GA3 recorded the longest shelf life of 31.33 days, followed by 1% GA3 (27 days) and 4% CaCl2 (22 days) over the control (15.667 days). Disease incidence days were highest for 3% GA3 (32.33 days) followed by 1% GA3 (28.33 days) and 4% CaCl2 (23 days) over control (16.667 days). The percentage of physical weight loss on the day of data recording was minimum for 3% GA3 treated fruits and maximum for control. Similarly, TA, TSS, and pH of treated fruits show significant results over control

Comparative study of titanium elastic nailing v/s dynamic compression plating for the management of fracture shaft of femur in adolescent age group

Background: Femoral fractures are one of the common long bones fractured in paediatric age group. Over the past 20 years, there has been a dramatic and sustained trend toward the operative stabilization of femoral shaft fractures in school-aged children. Femoral fracture demands stable fixation in adolescent.Methods: A retrospective cohort study was conducted in a tertiary care hospital. All children’s between the age 11 to 18 years with femur fracture managed with either TENS or dynamic compression plating between march 2014 to march 2017 were included into the study.Results: most common mode of injury was RTA. Middle third being the most common site for fracture. There was100% union in our study. The mean time of union in TENS group was 12 weeks and that of Plating group Was 13.1 weeks. Irritation at entry site was seen in 11 (22.9%) out of 48 patients. Malunion was seen in 9 out of 48 children’s in group a, whereas malunion in group b seen in 1 child. All the malunion was less than 5 degree and Varus being most common type of malunion. Limb length discrepancy in group A was observed in 5 patents (10.5%) out which 3 were shortening and 2 were lengthening. In group b 1pateint had shortening at end of follow up. In group B superficial infection was seen in 4 (15%) out of 33 children’s and in group A it was observed in 2 children’s (5%).Conclusions: we concluded that compression plating in adolescent age group especially older and obese children for the management fracture shaft of femur comparatively better than TENS.
