Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    DEVELOPMENT OF BELT TYPE SEED METERING MECHANISM.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-08-21) MORE, MAYAVATI SATYABHAN.; Gajakos, Prof. A. V.
    Seed sowing is an important and time bound operation for crop cultivation. At present, the sowing operation is done manually by broadcasting, dibbling, putting seed behind the plough and other methods or with the help of manual, animal or tractor drawn seed drills/planters. These have lower efficiency, poor quality seed placement and high cost of cultivation. Presently, among different sowing techniques, precision sowing by pneumatic seed metering is preferred, since it provides more uniform seed spacing than other methods for sowing. For sowing of soybean seed most commonly seed drill either bullock drawn or tractor drawn are used and they have some limitations in sowing of soybean seeds. Considering lack of precision in seed metering in case of existing sowing equipments and the very high initial cost involve in the existing precision pneumatic planters the efforts are made to develop a belt type seed metering mechanism for soybean crop which will help to minimize the problems and reduce the cost of existing soybean planting machines. The physical properties of soybean seed variety (JS-335) in terms of equivalent length, sphericity, Surface area, bulk density, angle of repose, angle of friction and thousand seed weight were observed as 6.69 mm, 83.76%, 93.89 mm2 ,703.52 g/m3, 22.77˚, 23˚ and 102.01 g, respectively. The belt type seed metering mechanism was tested for its quality parameters by taking the three levels of forward speed (2.5 km/h, 3.5 km/h, 4.5 km/h) and at three inclination angle (00, 100, 200) of seed metering belt. The overall best results were obtained at the forward speed of 2.5 km/h and at an 00 inclination angle of seed metering belt with seed missing index (29.70%), multiple index (0%), quality of feed index (60.70%), precision index (26.70%) and uniformity index (50%). The forward speed for this type of mechanism should be minimum with minimum inclination angle for getting better results and may be used for other seeds with different groove size on seed metering belt.
