ThesisItem Open Access COMPARISON OF BRINJAL PRODUCTION UNDER DRIP FERTIGATION WITH DIFFERENT FERTILIZER LEVELS AND TRADITIONAL METHOD OF FERTILIZER APPLICATION.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-09-19) ADAWADKAR, MAYUR PRAKASH.; Deshmukh, Dr. M. M.A field experiment was conducted to study the comparison of brinjal production under drip fertigation and traditional method of fertilizer application, at Dr. PDKV, Akola during November 2017 to May 2018. The experiment was laid out in randomized block design with five treatments which includes four drip fertigation levels (75, 100, 125, and 150 % of RDF) and control treatment of traditional fertilization at 100 % RDF and these all treatments are replicated four times. The study indicated higher plant growth, more number of branches, higher number of fruits per plant and enhancement in the yield under all drip fertigation levels. Yield of brinjal was maximum in treatment of drip fertigation at 150 % RDF (T4) (557.10 q/ha) and found at par with treatment of drip fertigation at 125 % RDF (T3) (554.88 q/ha). It was seen that yield of brinjal in treatment T4 was found to be higher than that of treatment T3, which was statistically at par. But the advantage in treatment T3 was requirement of 25 % less amount of fertilizer. Considering requirement of less amount of fertilizer in treatment T3 than treatment T4; the treatment T3 may be suggested as a best treatment. Minimum yield of brinjal was found in treatment of traditional fertilization at 100 % RDF. Higher irrigation water use efficiency 7.33 q/ha-cm was found in treatment of drip fertigation at 150 % RDF (T4) followed by treatment of drip fertigation at 125 % RDF (T3). On the basis of benefit cost ratio (3.22) and net monetary returns (267653 Rs/ha), it is economically viable for the farmers to adopt drip fertigation at 125 % RDF for brinjal production.ThesisItem Open Access SIMULATION OF WATER FRONT ADVANCE FOR ONLINE DRIP IRRIGATION SYSTEM BY USING HYDRUS-2D.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-09-06) THUTE, RANI SAHEBRAO.; Kale, Dr. M. U.Drip irrigation has gained widespread popularity as an economically viable method of applying water. A constraint of drip irrigation is the number of emitters and laterals required to adequately deliver water to plant roots. During irrigation the water content in the soil changes spatially and temporally. Water distribution in the soil is strongly dependent on the design parameters of the irrigation. For effective design of drip irrigation systems, the water dynamics in soil needs to be predicted using all design parameters. The modeling of water movement in soil requires the knowledge of the soil hydrological properties especially soil water retention curve and hydraulic conductivity-water content relationship. These two basic hydrological characteristics must be defined experimentally before it is possible to carry out numerical analysis of water movement in unsaturated and saturated soils. In the present study, HYDRUS-2D was used to study the moisture movement through soil under drip irrigation system. Richard’s equation was solved using HYDRUS and vGM parameters obtained by using ROSETTA were used as input for HYDRUS. The HYDRUS model was calibrated and validated for different discharge rate and volume application combination. The modeling results showed that the HYDRUS-2D simulated the soil moisture satisfactorily in terms of statistical parameters R2 and RMSE. Effect of different discharge of emitter with combination of different volume on moisture distribution pattern was also studied and results showed that as discharge rate and volume of water increased wetted diameter also increased upto 30 hours and decreased after 30 hours from time of application. For Akola station, it was observed that the distance between two emitters should not be more than 48 and 52 cm in case of 4 lph and 8 lph emitter respectively.ThesisItem Open Access 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.ThesisItem Open Access STUDY OF DRY SPELLS IN YAVATMAL DISTRICT USING GEOINFORMATICS.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-08-03) KOKATE, KIRAN MOHAN.; SATPUTE, Dr. G. U.The success or failure of crops particularly under rainfed condition is closely linked with the amount and distribution pattern of rainfall. The knowledge of onset of effective monsoon (OEM), its withdrawal, period of occurrence and distribution of dry spells during monsoon months are essential for crop planning and management of rainfed farming. The study on “Dry spells in Yavatmal district using geoinformatics” was undertaken with specific objectives of rainfall analysis at taluka level for onset of effective monsoon (OEM), dry spells and withdrawal of effective monsoon in Yavatmal district according to Ashok Raj (1979) criteria. The average monsoon seasonal rainfall in different taluka stations varied from 556.75 to 890.32 mm with coefficient of variation of 25 to 49 percent. The mean dates of onset and withdrawal of effective monsoon varied from 18th to 29th June and 17th September to 4rd October respectively at different taluka places in Yavatmal district. The average monsoon seasonal rainfall during low, medium and high rainfall years varied from 409.2 to 616.7 mm, 549.9 to 938.5 mm and 702.2 to 1201.0 mm respectively. The critical dry spells (CDS) in Yavatmal district varied from 1 to 3 in number during different years with an average of 2 Critical Dry Spells (CDS). The average starting date of CDS (in different monsoon months) varied from 19th to 28th June, from 13th to 24th July, from 12th to 20th August and from 6th to 19th September. The highest probability of occurrence of dry spells of different duration (2 to 3, 3 to 4, 4 to 5 and more than 5 week) during August, followed by September (except for 2 to 3 week duration dry spell) and July or June at almost of all talukas in Yavatmal district. The spatial variation of probability of occurrence of different duration dry spells indicated the maximum chances of occurrence in Arni, Darwha, Digras, Yavatmal, Babulgaon and Ner talukas and some parts of Ghatanji, Mahagaon and Kalamb taluka as compared to remaining talukas in Yavatmal district. The temporal variation in occurrence of different duration dry spells in four monsoon months indicated higher temporal variation in number of occurrence of 2 to 3 weeks duration events in all the monsoon months, followed by 3 to 4 weeks duration dry spell event only in August and September month and 4 to 5 week duration dry spell events in the month of August in different talukas of Yavatmal district. The spatial variation of available water holding capacity of soil in different talukas of Yavatmal district indicated that the available water holding capacity of the soils in the study area varies from 10 to 14 cm per meter depth of soilThesisItem Open Access WATER RESOURCE PLANNING OF MICRO WATERSHED USING GEOSPATIAL TECHNIQUE.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-09-03) DONGARDIVE, MILIND BHIMRAO; PATODE, Dr. R. S.Geospatial Techniques like Remote Sensing (RS) and Geographical Information System (GIS) were used for land and water management action plan for some part of Purna-Tapi micro watershed in Akola district, Maharashtra. Keeping in view the need of micro level planning and usefulness of modern tools and technology a study on water resource planning of water resources for micro watershed was conducted. The objectives of the present research work were to prepare the thematic maps of land use/ land cover, soil, slope and drainage using satellite imagery data and survey of India (SOI) toposheet, morphometric analysis of micro watershed and to integrate all the maps under GIS environment to prepare the water resource management plans for the study of micro watershed. The study will be helpful in identification of sites for construction of different soil and water conservation structures like water harvesting structures, check dams, farm ponds, percolation tanks, nala bunds, nala widening and deepening of drainage network etc. Different soil and water conservation works are suggested under water resource action plan with specific sites, locations and maps. The study will be helpful in sustainable development of the natural resources of the micro watershed with the proper implementation of the proposed action plans.ThesisItem Open Access COMPARISON OF BRINJAL PRODUCTION UNDER DRIP FERTIGATION WITH DIFFERENT FERTILIZER LEVELS AND TRADITIONAL METHOD OF FERTILIZER APPLICATION.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-09-19) ADAWADKAR, MAYUR PRAKASH.; Deshmukh, Dr. M.

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.
