Cultivation of potato is highly labour intensive when it is carried out by labours with kodali and pavda. Delay in planting due to shortage of labour during season causes progressive decrease in yield. The area under potato crop cultivation and yield may be increased if planting is mechanized through introduction of low cost planting technologies. In India, there are medium and big tractor (35 hp or more) operated potato planters which are manufactured by the various farm machinery manufacturers. During last few years mini tractors of 20 hp or less than 20 hp are being popularized and are being manufactured by various tractor companies but there is lacking of matching equipment for these mini tractors. So, according to RNAM test code, mini tractor mounted two row automatic potato planter was designed and developed for sowing whole potato tubers (Kufri pukhraj) at (60 cm x 20 cm) in the field. The total manufacturing cost of the planter was worked out Rs.49000/-. The size of potato used for the experiment was in the range of 35 to 45 mm and the tractor used was 18 hp mini tractor. Evaluation of the planter was done in the laboratory for calibration at three different speeds. Performance evaluation of the planter in the field was carried out at three different speeds (1.5 km/h, 2.0 km/h & 2.5 km/h) and at three different levels of front ballasting (50 kgf, 100 kgf, & 150 kgf). The effect of these two independent variables on theoretical field capacity, effective field capacity, field efficiency, draft requirement, power requirement, fuel consumption, wheel slippage and skid of ground wheel, missing and multiple percentage and cost of operation was evaluated in field conditions.ThesisItem Open Access DEVELOPMENT OF BATTERY POWERED INTER AND INTRA-ROW WEEDER(Department of Farm Machinery and Power Engineering College of Agricultural Engineering and Technology Anand Agricultural University, Anand, 2019) Shamkuwar Snehal Vidyasagar; Dr. Pankaj GuptaEfficient weed management is necessary to increase the productivity with judicious use of inputs. Weed control is one of the most difficult tasks in crop production that accounts a considerable share of cost involved. There are many methods for weed management, but out of those methods, chemical methods are most popular. These methods are hazardous for environment as well as for human health. To ensure the food security, growing demand for organically produced food and sustainable development of agriculture, it is critically important to develop chemical free agricultural products. This has necessitated the shift towards mechanical weeding. Although, many weeders have been developed to remove the weeds from the row, but weeds in intra row remain inattentive, which are indispensable to be removed for more crop production. Although, the weed control in intra row region is challenging for mechanical weeding, efforts required for development of low cost, effective and efficient inter and intra row weeder with less drudgery for small farmers. Considering all, a push type manual weeder was developed for inter as well as intra row weeding simultaneously.ThesisItem Open Access DEVELOPMENT OF TRACTOR DRAWN ELECTRONIC MULTI-CROP PLANTER CUM FERTILIZER APPLICATOR FOR PRECISION FARMING(DEPARTMENT OF FARM MACHINERY AND POWER ENGINEERING COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY GODHRA, 2019) Sidhartha Shankar Baral; Dr. R. SwarnkarPlanting is one of the most important operations in crop productions. Optimum depth and time are essential which affect the yield of the crop during the time of planting. In the present day advanced agronomic practices, seed genetics and on-farm technology are essential to deliver optimal yield. While using fewer resources, precision planting has an important place.ThesisItem Open Access DEVELOPMENT OF BULLOCK DRAWN BATTERY POWERED SOWING MACHINE(DEPARTMENT OF FARM MACHINERY AND POWER ENGINEERING COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY, GODHRA, 2019) Monpara Alpeshkumar M.; Dr. R. SwarnkarSowing is one of the most important operations in raising crops. Timely sowing has a dominant effect on germination of seed, plant growth, plant population in the field and ultimately on the total production. The most important source of power in the farm all over the India and especially in Gujarat is bullocks. Bullocks are the largest contributor of farm power in Gujarat and yet, the major source of power for marginal, small and even medium farmers who account for more than 60 per cent of total agricultural holding. Since the majority of farmers are small and marginal using animal as a source of power and to provide a better option, a bullock drawn battery powered sowing machine was developed at CAET, AAU, Godhra for the small-scale farmers. Bullock drawn battery powered sowing machine consist of main frame, furrow openers, seed box, seed metering mechanism, DC motor as power unit for metering mechanism, seed tube and 12V rechargeable battery. The seed rate during calibration in laboratory for three crops (soybean, pigeonpea and maize) at 3.0 km/h were recorded as 22.82 kg/ha, 12.08 kg/ha and 20.0 kg/ha, respectively. Performance evaluation of the sowing machine in the field was carried out for three different angle of pull (20°, 25°, 30°) and at three different levels of angle of penetration of furrow (20°, 25°, 30°).ThesisItem Open Access DEVELOPMENT OF BULLOCK DRAWN PLASTIC MULCH SHEET CUM DRIP LAYING MACHINE(DEPARTMENT OF FARM MACHINERY AND POWER ENGINEERING COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY, GODHRA, 2019) Kothiya Amitkumar V.; Dr. B. K. YaduvanshiPlastic mulch sheet has shown significant effect over farming technique. It has several advantage like weed control, moisture conservation, yield enhancement etcetera. Now a days drip irrigation is become necessity. When mulching is practiced along with drip irrigation, provides best results. At present, Farmers have to lay the drip line and mulching sheet manually. Manual operations are cumbersome and consume much time. Some automatic mulch and drip laying machines were developed but these are not economical. To provide a better option, a mulch sheet cum drip laying machine was developed at PAE, AAU, Dahod for the small farmers. Bullock drawn plastic mulch sheet cum drip laying machine consist of multipurpose tool carrier (main frame), mulch roll carrying unit, dripline roll carrying unit, mulch sheet pressing cum transport wheel, mulch sheet covering unit, mulch sheet punching mechanism. The performance of the machine was evaluated by determining the draft, power requirement, theoretical field capacity, effective field capacity, field efficiency, punching uniformity, punching efficiency and mulch sheet covering. Machine was tested at two levels of mulch width 0.75 m & 1.20 m and three levels of thickness (25, 30, 40 micron). The results were analysed statistically using factorial randomize block design. Average forward speed of developed machine was found as 1.98 km/h. Draft was found minimum (29.14 kgf) for 0.75 m width and 25 micron thickness.ThesisItem Open Access DEVELOPMENT OF WIND AND SOLAR POWERED BIRD REPELLER(DEPARTMENT OF FARM MACHINERY AND POWER ENGINEERING COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY, GODHRA, 2019) Chauhan Virendrasinh J.; Dr. R. SwarnkarCrops production and grain efficiency decreases due to poor maintenance of the farm and pest attack. Birds eat sown grains which considering decreases plant population, hence other all production. Wind and solar powered bird repeller was best solution for small and marginal farmers to protect farm from bird. A solar and wind powered bird repeller was developed in this study to small and marginal farmers, It consisted of two units, in which one was wind powered and other one was solar powered.

The maximum sound level recorded at 1 m distance was 121.6 dB (stainless steel), 116.2 dB (bronze), 114.5 dB (brass) and different materials with 300 rpm of motor, 10ft height.ThesisItem Open Access DEVELOPMENT OF AUTOMATED GUIDED VEHICLE FOR AGRICULTURAL SPRAYING OPERATION(DEPARTMENT OF FARM MACHINERY AND POWER ENGINEERING COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY, GODHRA, 2019) Bhabhor Mukeshkumar S.; Dr. Pankaj GuptaIndia is an agricultural dependent country, as still more than 55% population depends upon it for their livelihood. But, most of the farmers are very poor due to the low income from the agriculture. To enhance the income from agriculture, it is essential to increase the productivity or to bring more land under cultivation, which is limited. Mechanization of field operations is one way to increase productivity as agricultural machinery and implements are capable of doing field operations with precision and in lesser time. Judicious management of all the inputs is essential to increase production, profitability and the sustainability of such a complex system. Thus, precise application of inputs and agricultural operations are needed. Apart from these, Indian agriculture is facing challenges of ever increasing population and day by day shortage of agricultural labour. Thus, time has now arrived to exploit all the modern tools available and agricultural science together to improve economic and environmentally sustainable crop production. The advent of autonomous system architectures gives us the opportunity to develop a new range of flexible agricultural equipment based on small, smart machines that reduces waste, improves economic viability, reduces environmental impact and increases food sustainability.ThesisItem Open Access DEVELOPMENT OF PULL TYPE BATTERY OPERATED MULTI-CROP PLANTER FOR WOMAN FARMERS IN TRIBAL REGION OF GUJARAT(DEPARTMENT OF FARM MACHINERY AND POWER ENGINEERING COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY ANAND AGRICULTURAL UNIVERSITY, GODHRA, 2019) Chavda Shaktisinh; Dr. R.
