    DESIGN AND DEVELOPMENT OF TRACTOR OPERATED GROUNDNUT COMBINE FOR HARVESTED CROP
    (Acharya N.G. Ranga Agricultural University, 2018) VENNELA, BASIREDDY; RAMANA, C
    Groundnut (Arachis hypogaea L.) is an important oilseed crop in India cultivated in an area of 6.7 million hectares with a production of 7.0 million tonnes annually. The crop can be grown successfully in areas receiving the rainfall ranging from 600 to 1250 mm. The best soils for groundnut crop are sandy loam, loam and medium black with a good drainage system. The present practice of manual harvesting and threshing consumes huge amount of labour to a magnitude of about 175 to 200 women h ha-1. It is very tedious and time consuming operation and is being adopted by for small scale farming. The manual method is the process of harvesting groundnut manually by hand, using expensive human labour. Since it is a labour intensive operation, scarcity of labour is often experienced during the peak harvesting season. One of the solution for reducing losses and dependency on human labour is to mechanize both harvesting and threshing simultaneously in groundnut cultivation. Several efficient independent machines are available for harvesting and threshing separately by manual feeding, but collecting harvested crop and feeding into thresher is again a labour intensive operation. Moreover, the harvesting requires maximum energy and combining may not be feasible with a commonly available tractor. Hence, the combine was developed by designing collecting, conveying and threshing systems for harvested groundnut crop. In this process, available machines like digger shaker and wet pod thresher were evaluated and synchronized the harvested quantity with the threshing ability of selected threshing mechanism. The tractor drawn groundnut digger shaker implement was tested in a total area of 0.27 hectares of sandy loam soil. Trials were carried out and the crop was sown with recommended row spacing 30 cm and 10 cm intra row spacing. The results revealed that plant height, plant width, root length, number of plants, number of pods per plant and number of filled and unfilled pods at the time of harvest was recorded as 35.8 cm, 17.53 cm, 25.27 cm, 27.12, 20.04 and 7.08 respectively. The highest average effective field capacity obtained using tractor drawn groundnut digger shaker was 0.35 ha h-1. The highest average field efficiency of 80.10% recorded for tractor drawn groundnut digger shaker at a soil moisture content of 12%. The haulm yield of the windrows formed for a harvested distance of 10 m was 1.011 kg for xv single row, 2.128 kg for two rows and 3.518 kg for three rows. Performance of wet pod thresher selected for a design was observed at a feed rate of 870 kg h-1 and the thresher output was 227.25 kg h-1 with the total number of the labours of 7. The designed collecting unit was provided with a rake angle of 600. The maximum conveying efficiency of the groundnut combine of 82.40% for the lateral conveyor was obtained at a combination of 1.19 ms-1 peripheral velocity of picker conveyor, forward speed of 1.59 km h-1 and 10 cm spacing of flaps. From the statistical interaction it was confirmed that the second speed of the prime mower i.e. 1.59 km h-1 is optimal for the collecting, conveying and hence the forward speed of the operation was fixed as 1.59 km h-1 for ensuring better collection. Similarly, the spacing of the flaps out of 5, 10 and 15 cm, the 10 cm spaced flaps gave best results in all independent trials with respective conveying of collected crop mass. Hence spacing between flaps designed to be 10 cm. The highest lateral conveying efficiency of 92.40% was obtained at a combination of Sf2-F2-Pv2 i.e. 10 cm - 1.59 km h-1- 1.19 ms-1 which confirmed for designed collecting mechanism. In the design of vertical elevator, the increase in slat spacing from 50 to 100 mm increased the conveying efficiency at all selected levels of peg end projections and peripheral velocity. The highest vertical conveying efficiency of 92.56% was obtained at a combination of S2-Pf2-Pv2 i.e. 10cm -1200- 1.19 ms-1, which confirmed results obtained during the trial. The performance of the developed combine for the harvested crop was observed that efficiency of the lateral and vertical conveyor was 92.40 and 92.56 respectively and the effective field capacity was 0.122 ha h-1 with an average fuel consumption of about 4.67 l h-1. The threshing efficiency of the developed groundnut combine was 82.54% compared to wet pod thresher because of slow feeding of the crop into the thresher from the trough. It was observed that the operation of groundnut combine resulted in 74.92 % saving in cost when compared to conventional method of manual collecting and hand stripping. It was also concluded that, the number of hours required for operating the developed combine harvester was 6.67 machine hours + 16 man hours which was least compared to treatment T3 conventional method of collecting and threshing was 200 h. As cost reduction between T1 and T2 were 1253.75 Rs ha-1 and 1370.94 Rs ha-1, the time required for collecting and threshing was more in T2 which is of 5.7 machine hours and 56 man hours, whereas for T1, it requires only 6.67 machine hours and 16 man hours. An overall saving of man hours from the developed machine was 92% and 71.42% over T3 and T2 respectively. It was observed that the output capacity of the thresher was 216.6 kg h-1 and the broken pod loss was 1.27%. The threshing capacity was 83.58% and the cleaning efficiency was 81.68%. The machine was tested in the experimental plot and field efficiency was found to be 76.72% with optimized design parameters at 1.59 km h-1 forward speed.

    EFFECT OF DIFFERENT IMPLEMENTS FOR IMPROVING THE PRODUCTIVITY AND QUALITY OF SUGARCANE RATOONS (SACHARUM OFFICINARUM L.)
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) VENNELA, BASIREDDY; Dr. AUM SARMA
    The experiment entitled “Effect of different implements for improving the productivity and quality of Sugarcane ratoons (Sacharum officinarum L.)” was conducted during Eksali, 2014 on red sandy loam soils of Agricultural Research Station, Basanthpur, Medak Dist. The treatment includes conventional and mechanical management practices of sugarcane ratoon laid in four replications. The field performance of different ratoon implements (Disc off barrier, Ratoon manager, Mini rotoweeder, Ridger, Mini plough, Conventional plough and Harvester) was evaluated in three village viz., Basanthpur, Kalbemal and Madgi of Medak District. Among the three villages, Basanthpur village had recorded highest values for all the ratoon implements. The effective field capacity of the disc off barrier, Ratoon manager, Mini rotoweeder, Ridger, Mini plough, Conventional plough and Harvester in Basanthpur are 0.18 ha h-1,0.45ha h-1, 0.31 ha h-1, 0.04ha h-1,0.088 ha h-1, 0.02 ha h-1, 0.34 ha h-1 respectively , with a fuel consumption of 0.013m3ha-1,0.0152 m3ha-1, 0.018 m3ha-1,0.015 m3ha-1, 0.0125 m3ha-1 , 00 m3ha-1,0.020 m3ha-1respectively. Biometric observations of growth parameters, yield attributes and yield were recorded and analysed. Accordingly, the effect of different implements on soil parameters and root growth was also recorded. Significantly highest and at par tiller number at 75 and 120 DAP, plant heights, millable canes, single cane weight, cane yield, sugar yield and cane girth(96.750, 162.91, 333.60, 102.280, 1.39, 148.46, 19.80, Name of the Author : BASIREDDY VENNELA Title of the thesis : “EFFECT OF DIFFERENT IMPLEMENTS FOR IMPROVING THE PRODUCTIVITY AND QUALITY OF SUGARCANE RATOONS(SACHARUMOFFICINARUML.)” Degree to which it is submitted : Master of Technology Faculty : Agricultural Engineering Major field of study : FARM MACHINERY AND POWER Major Advisor : Dr.AUM SARMA University : Acharya N.G Ranga Agricultural University Year of Submission : 2015 2.97) were recorded in T6 (Improved method running with stubble shaver + disc off barrier + inter cultivation by tractor + mechanical harvesting) and T5(83.15, 152.07, 319.04, 99.643,1.36, 136.82,18.54, 2.88) (Improved method running with stubble shaver + intercultivation by tractor + manual harvesting) treatments. While, significantly lowest and at par crop parameters were noted with T1 (Conventional with manual shaving + inter cultivation by draught animal + manual harvesting) and T2 (Conventional with manual shaving + inter cultivation by tractor + manual harvesting) treatments. Higher root mass of 205.69 – 211.36 g was recorded in T4, T5 and T6 treatments which involve the use of stubble shaver, disc off barrower and a ratoon manager. On the other side, the conventional treatments in which shaving was done manually has registered a root mass of 171.65 – 188.97 g. Maximum decrease of 1.38 gm cm-3 in bulk densitywas observed in T6 while the minimum was observed in T1. On the other hand, the pore space was maximum (38.85%) in T6 and minimum in T1 (31.62%). The crop fetched maximum gross and net returns of Rs.385996 and 263108 ha-1 respectively due to T6. Whereas, the minimum gross returns of Rs. 275600 and 168820ha-1, respectively were obtained due to T1. Therefore, ratoon management with stubble shaving, disc off barring followed by intercultivation by tractor and mechanical harvesting was foundeconomical with a benefit cost ratio of 2.14 followed by T5 with a benefit cost ratio of 2.08.
