How Public Extension Services Affect Farm Income in Rural India?
Using 70th round of a nationally representative survey of farm households from the National Sample Survey Office (NSSO) conducted in 2013. This study examines the determining factors of participation in public extension services and their impact on farm income in rural India. To account for selection bias, the effect of participation in public extension services in terms of farm income in rural India was appraised using propensity score matching (PSM). The findings suggest that factors such as age, education, formal training in agriculture, higher consumption expenditure level, farm size, and exposure to mass media significantly determine participation in extension services. Further, it was also found that public extension services have significantly contributed to an increase in the farm income of the participants. These shreds of evidence provide an important impetus pointer from a policy perspective for the proper household targeting for participation in public extension services in rural India.
A Study on Determination of Optimum Partial Gear Ratios of Bevel Helical Gearboxes
This paper introduces a study on the optimal design of a two-stage bevel helical gearboxe. The objective of the study is to determine the optimal partial gear ratios of the gearbox to achieve the minimum gearbox bottom area. To do that, a simulation experiment was conducted. From the results of the experiment, the influence of main design parameters including the total gearbox ratio, the face width coefficient of bevel gear, the face width coefficient of helical gear, the allowable contact stress of the first and the second stages, and the soutput torque on the optimal gear ratios was investigated. In addition, a regression formula for calculating the optimal gear ratio for the second stage has been proposed.
Management of Foliar blight of Wheat (Bipolaris sorokiniana and Alternaria triticina) through the application of Fungicides and Plant Extracts
In the present work, a single, combination of fungicides and plant extracts were evaluated for effective management of foliar blight of wheat caused by complex pathogens namely Bipolaris sorokiniana and Alternaria triticina under in vivo condition. Among single fungicides spraying Propiconazole (1g /L) proved to be the most effective treatment in which the least disease score (02), highest grain yield (66.4 q/ha), and highest plant height(88.6 cm) were recorded. Among the combination of fungicides spraying Nativo (Tebuconazole + Trifloxystrobin) proved to be the most effective treatment in which the least disease score (01) highest grain yield (69.2 q/ha) and highest plant height (89.1 cm) were recorded. Among single plant extracts spraying garlic (5%) proved to be the most effective treatment in which the least disease score (13), highest grain yield (66.3 q/ha), and highest plant height(88.4 cm) were recorded. Among the combination of plant extracts spraying (Ginger + Garlic) proved to be the most effective treatment in which the least disease score (11), highest plant height (89.1 cm), and highest grain yield (67.9 q/ha) were recorded.
Ecofriendly Approach to Improve Drapability and Process Optimization of Aminosilicone Treatment on Jute Fabric
The current research work sets the radar towards the finishing of jute fabric by application of aminosilicone softener by pad-dry-cure method, which was set after optimization of concentration, pH, material to liquor ratio, treatment temperature and time, drying temperature and time & curing temperature and time. The impregnation of the finish into the jute fabric resulted decrease in bending length, flexural rigidity and drape coefficient, thus causing improvement in softness and drapability of jute fabric. The finish also had a positive impact in controlling the colony forming units of Gram +ve bacteria (Staphylococcus aureus) and Gram -ve bacteria (Escherichia coli). There was no comparable difference in ultra-violet protection property of the treated jute fabric. The surface morphology was studied by scanning electron microscopy. This finish is of extreme importance because it not only improves the drawbacks of jute fabric but also it is environmentally benign and non-toxic.
Development of a Planning and Mission Supervision System for a Ground Agricultural Mobile Robot
A series of algorithms was implemented to plan optimal routes and generate smooth trajectories, for optimal and safe navigation of an agricultural robot. For the generation of optimal routes, the algorithm called A* was implemented, while for the smoothing of the trajectory the algorithm called Bezier curves was utilized. The system is capable of generating smooth trajectories with a resolution of up to one centimeter, in less than a second, performing by teleoperation the monitoring and remote control of the robot with frequencies of 2 Hz, which makes it suitable for robots in agricultural tasks. The developed software permits demarcating, from an aerial image, the crop rows or other obstacles present, and once the optimal route is generated to visualize its smoothing and geo-referencing, to provide a sequence of geographic coordinates, through which the robot must navigate.
