    PERFORMANCE EVALUATION OF FARMYARD MANURE PULVERIZER CUM SPREADER
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) NKR GURUDATT MADDU; Dr. S. JOSEPH REDDY
    On one side of the coin negative impacts coupled with escalating prices of mineral fertilizers and on other side high demands of nutrients to soil due to intense cultivars of high yielding varieties, the use of organic matter is necessary to meet the nutrient demands with low cost. In India application of farmyard manure (FYM) to the agricultural fields has been generally accepted practice, which improves soil physical, chemical and biological properties of soil. Keeping in view the problems of not meeting the desired agronomic rates and disintegration of large manure un-decomposed clods during manual application of FYM to the field, a machine (FYM pulverizer cum spreader) was developed by RARS, Nandyal to pulverize and spread the manure simultaneously to the fields. Pulverization of large un-decomposed FYM clods to 0 to 40 mm size encourages the faster decomposition when hits the lands due to the more surface area exposed for the attack of microorganisms present in the soil, environment and FYM. To meet the desired FYM application rates to the fields in required pulverized form, it is necessary to study the physical properties of manure affecting the performance of the machine and behavior of the machine at different component settings and operated under prescribed levels. Hence, a study was carried out on the performance evaluation of the FYM pulverizer cum spreader. The machine parameters with levels viz., feed control shutter opening (half open and full open), number of blades per flange of rotor (2, 3, and 6) and operational parameters viz., spreader peripheral velocity (4.72 ms-1, 6.92 ms-1and 7.86 ms-1) spreader forward speed of (2 Km h-1,3 Km h-1 and 5 Km h-1) were selected to study the effect on bulk density, clod size distribution and FYM application rate. Based on the study, the machine and operational parameters were optimized for minimum bulk density, higher percentage of 0 to 40 mm clod distribution and desired range of agronomic application rates. The experiments were carried out at stationary condition as well as in field conditions. The experiments revealed that, the decrease in bulk density and increase in percentage of 0 to 40 mm clod size distribution was observed when the rotor peripheral velocity was increased from 4.72 ms-1 to 7.86 ms-1 and numbers of blades were increased from 2 to 6. The lowest bulk densities of 0.510 g cm-3and 0.515 g cm-3and higher 0 to 40 mm clod size percentages of 78.28 and 66.55 was recorded at peripheral velocity of 7.86 ms-1 and 3 number of blades for both half and full shutter opening of the machine respectively. The application rate was increased when rotor peripheral velocity increased and decreased with increase in forward speed. The agronomic application rates of 5.8 t ha-1and 12.6 t ha-1with minimum bulk density and higher percentage of 0 to 40 mm clod size distribution was observed at forward speed of 3 Km h-1, peripheral velocity of 7.86 ms-1 and 3 blades per flange of rotor at half shutter and full shutter opening. A prototype FYM pulverizer cum spreader was developed and evaluated under field condition with the best optimized variables derived from the experimental trails. The bulk density, clod size distribution and application rate was observed as 0.512 g cm-3 & 0.521 g cm-3, 75.99 % & 64.45 % and 5.9 t ha-1 & 12.5 t ha-1 at half and full shutter opening area respectively. The cost of operation of FYM pulverizer cum spreader works out to be Rs.620 per acre when the machine is used for dry FYM pulverizing cum spreading operation. There was a saving of Rs.504 per acre over traditional method of spreading.

    DEVELOPMENT AND EVALUATION OF MULTI CROP PRECISION PLANTER
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) SRIGIRI, DOPPALAPUDI; Er. G. VEERA PRASAD
    Sowing is one of the most important operations in crop production. The time and method of sowing decisively influence the germination and hence production. Sowing at optimum depth and time is essential which will affect the yield of the crop. Sowing in late season will decrease yield about 35%. With the present day advanced agronomic practices, seed genetics and on- farm technology to deliver optimal yield while using fewer resources, precision planting is not out of place. Although many planters having different seed metering mechanisms i.e. inclined plate, cup feed type and roller with cells on periphery for the application of single seed at a time has been developed, their performance is not up to the mark due to nonperformance in obtaining required spacing for irregular shaped seed crops like Paddy, Maize, Black gram etc. It is a well-known fact that the bulk of agricultural production in the India is in the hands of the small holder farmers who depend very much on tools with very low mechanical advantage. Most of the commercial equipment available in market are very expensive to procure and manage by the small holder farmer. A study was taken up to develop a manual planter suitable for different crops without changing metering mechanism and to evaluate its performance. The planter was developed at workshop, Department of Farm Machinery and Power, College of Agricultural Engineering, Bapatla. The planter was evaluated in the field at College of Agricultural Engineering, Bapatla as per BIS test code IS 6316: 1993 for Bengal gram, red gram and paddy. The cost of operation of the planter was compared with manual sowing cost. The capacity of planter was found to be 2.25, 2.87 and 1.91 kg h-1 for Bengal gram, red gram and paddy respectively. The planter capacity is more for red gram compared with Bengal gram and paddy. The seed rate required for planter was observed to be 30.67 kg ha-1, 24.76 kg ha-1 and 36.26 kg ha-1 for Bengal gram, red gram and paddy respectively. The planter requires less seed rate than manual sowing. The seed damage was found to be 1.96 %, 1.41 % and 0.89 % for Bengal gram, red gram and paddy respectively. The seed damage was due to size of the groove on metering cone and rupture of the seed between hopper and metering cone. The missing rate was found to be 4.38 %, 2.94 % and 3.67 % for Bengal gram, red gram and paddy respectively. It was also observed that missing rate is less for red gram compared to Bengal gram and paddy. The effective field capacity of the planter was found to be 0.081 ha h-1, 0.152 ha h-1 and 0.059 ha h-1 for Bengal gram, red gram and paddy respectively. The field efficiency was found to be 77.33 %, 81.06 % and 78.66 % for Bengal gram, red gram and paddy respectively. The depth of sowing was found to be 0.0410 m, 0.0362 m and 0.0355 m for Bengal gram, red gram and paddy respectively. The seed to seed spacing was found to be 0.2820 m, 0.2742 m and 0.2664 m for Bengal gram, red gram and paddy respectively. This variation is due to some early dropping of seed from hopper sometimes at edges of metered cone to furrow openers. The germination was found to be 96, 98 and 98% for Bengal gram, red gram and paddy respectively. The number of plants per square metre was found to be 30, 26 and 47 for Bengal gram, red gram and paddy respectively. The number of plants per square metre was more for paddy than Bengal gram and red gram. The cost of planter was found to be Rs. 4500 with an operating cost of Rs. 41.34 per hour. The cost of operation was found to be Rs. 474.99, Rs. 271.60 and Rs. 700.29 per ha for Bengal gram, red gram and paddy respectively. The cost of sowing for red gram was found to be less with planter than compared to other crops. The cost of sowing was less with planter compared to manual sowing in all the crops. Finally it was concluded that the seed rate requirement of the planter was less compared to traditional method of sowing. The cost of sowing was less with the planter compared to traditional methods of sowing. The planter is useful equipment for small and marginal farmers who cannot afford large machinery. Key words: Development, Evaluation, Bengal gram, Red gram, Paddy, Planter, Operating cost.

    (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.
