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.

    MODIFICATION AND PERFORMANC EVALUATION OF TRACTOR OPERATED PIGEON PEA STEM CUTTER.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-08-21) GAWAI, KIRAN SUBHASH.; Thakare, Dr. S. K.
    A pigeon (Cajanus cajan L. Mills) stem cutter was developed in the department and its performance was evaluated in the field. During testing equipment problem were observed in the improper cutting, height of cut was more than requirement, Conveying lugs were getting bend during conveying operation, Plant guiding system was not guiding the plant up to the last, and shaft on the gearbox getting bend results in improper transmission and Visibility to operator was also poor. Thus, the modification in different system was carried out by the department of Farm Power and Machinery, Dr. PDKV, Akola. Improper cutting of plants was due to low sharpness, when stem were in bunches, cutting is not possible at that situation. Due to peripheral effect of moving blade, plant of pigeon pea bends and hence the stem was move out of the cutting area of the blade. Hence stem remains uncut and the same plant get choked in revolving pulleys. In view to avoid this, curve sharp blade introduce in the equipment. When plant is moved in the conveying system, lugs bend to the opposite side of travel due to the pressure of pushing the plants. Lugs don’t hold the stem properly because of more distance in the lugs and hence affects the conveying of plants. Gear box shaft connected to first sprocket of transmission system frequently disengage as it gets bend during operation. Proper arrangement was introduce to solve all predicted problems to the equipment. The modified pigeon pea stem cutter was tested in the field and was found working satisfactory. Cutting efficiency increased due to due to reducing height of cut. Thus the Conveying efficiency increases due to strengthening conveying system and introducing rectangular frame on right and left side of plant guiding system. Support was also provided to individual lugs to avoid bending of lugs due to pressure. To increase grip on the stem distance between two lugs was reduced which was working satisfactorily. The M.S. shaft was replaced by shaft of steel alloy which work satisfactorily. As there was visibility problem to the operator during working of machine, a was window introduce exactly at the center on conveying platform to observe the working of the equipment The performance of newly modified equipment was evaluated in the field at the operating speed of 3 and 3.5 Km/hr the maximum cutting efficiency was found 90.56 % and 87.27 % at 3 Km/hr and 3.5 Km/hr speeds respectively. Conveying efficiency was found 91.66 % and 89.58 %. Whereas the field efficiency was observed 82.59 % and 85.71 % at the above mentioned speeds respectively. The plant damage was found 5.66 % and 7.27 % at 3 Km/hr and 3.5 Km/hr speed of operation. The cost of operation was observed 58.07 % less compared to manual harvesting of the pigeon pea crop.
