    IMPACT ASSESSMENT OF WASTEWATER IRRIGATION ON SOILS AND CROPS IN PERI-URBAN AREA OF NAGPUR.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-12-03) PANGUL, CHETAN SURESH.; Mhaske, Dr. A. R.
    The wastewater of Nagpur city discharged into Nag River is utilized for irrigating vegetables and other agricultural crops without giving due consideration to soil, plant and human health. Therefore, the study was conducted to see impact of wastewater irrigation on soils and crops in peri-urban area of Nagpur. The wastewater and soil samples were collected from five different villages from the farmers’ fields in Kamptee and Kuhi talukas of Nagpur district where the wastewater is continuously used for irrigation over the years. For reference (control), well water and soil under well water irrigation were also collected from nearby area of each selected wastewater sites. The samples of different crops were collected from the fields irrigated with wastewater and well water. The pH of wastewater was in the range of 7.18-7.60 with higher EC (0.64-0.85 dSm-1), low BOD (10.98-27.88 mgL-1) and COD (25.25-60.23 mgL-1). The concentration of HCO3-, Cl-, SO42-, Mg2+, Na+, K+, total hardness, micronutrients (Fe, Mn, Cu and Zn) and heavy metals (Cd, Cr, Pb and Co) in wastewater was higher than that of well water. The concentration of trace elements like Mn, Cu, Cd, Cr and Co in wastewater was higher than the recommended safe limit hence wastewater use in agriculture indicating chances of toxicity hazards to soil and plant. The soils under long term use of wastewater irrigation showed relatively lower bulk density (1.27-1.33 Mg m-3) and saturated hydraulic conductivity (1.40-1.48 cm h-1). The wastewater irrigated soils showed slightly lower reaction (pH 7.33-7.60) with higher EC (0.70-0.84 dSm-1), high organic carbon (5.41-5.53 g kg-1). The available N, P, K status of wastewater irrigated soils was appreciably higher as compared to those in the well water irrigated soils. The concentration of Fe, Mn, Zn, Cu, Cd, Cr, Pb and Co was comparatively higher in wastewater irrigated soils and found above recommended safe limit. The concentration of these elements was observed to be approaching their critical concentration and may lead to soil contamination in near future if the same levels of wastewater are applied on these soils. The concentration of micronutrients (Fe, Mn, Zn and Cu) and heavy metals (Cd, Cr, Pb and Co) in wastewater irrigated crops like wheat, chickpea and spinach was higher than that of well water irrigation. Thus, it can be concluded that the long-term use of wastewater for irrigating agricultural crops was beneficial in improving soil chemical properties like organic carbon, available N, P and K, micronutrients (Fe, Mn, Zn and Cu). However, higher concentration of bicarbonates, chlorides, sodium and potassium and heavy metals (Cd, Cr, Pb and Co) in wastewater showed considerable contamination of soil and plant which may enter in the food chain hence the continuous use of wastewater in agriculture for irrigation should be done cautiously.

    DRY SPELL STUDIES IN BULDHANA DISTRICT USING GEOINFORMATICS.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-10-04) PAGAR, NITIN KARBHARI.; Satpute, Dr. G. U.
    The onset of southwest monsoon over various parts of the country can be early, timely or late as compared to the set of normal dates. Initiation of monsoon and its progress depends on air movement and land topography which could be either rapid or slow or sometimes there could be prolonged stagnation in the advance of monsoon. The timing of the monsoon onset and knowledge about the occurrence of dry spells during monsoon period has vital importance in the agricultural sector. The present work on “Dry spell studies in Buldhana 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 monsoon in Buldhana district according to Ashok Raj (1979) criteria and the spatial variation of the above said monsoon events. The average monsoon seasonal rainfall in different taluka stations in Buldhana district varied from 581.8 to 792.7 mm with coefficient of variation of 27.2 to 29 percent. The mean dates of onset and withdrawal of effective monsoon varied from 20th June to 5th July and 22nd to 30th September respectively at different taluka places in Buldhana district. The average monsoon seasonal rainfall during low, medium and high rainfall years varied from 405.8 to 560.8 mm, 519.8 to 761.4 mm and 760.5 to 1055.8 mm respectively in the district. The critical dry spells (CDS) in Buldhana district varied from 1 to 4 in number during different years with an average of 2 CDS. The average starting date of CDS in different monsoon months varied from 16th to 25th June, from 15th to 28thJuly, from 12th to 28th August and from 8th to 18th September. The highest percent chances of occurrence of dry spells of different duration (2 to 3, 3 to 4, 4 to 5 and more than 5 week) was found in August, followed by July and September at almost all talukas in Buldhana district. The spatial variation study of probability of occurrence of different duration dry spells indicated the maximum chances of occurrence in Khamgaon, Mehkar, Sangrampur and Shegaon talukas and in some parts of Nandura, Sindkhed Raja, Lonar, Jalgaon Jamod, Buldhana, Motala and Chikhli talukas as compared to remaining talukas in Buldhana district. The temporal variation in occurrence of different duration dry spells indicated higher temporal variation of 2 to 3 week duration events in almost all the talukas of Buldhana district in different monsoon months except for June during which the chances of occurrence of dry spells were very less in few central talukas. The higher temporal variation in occurrence of 3 to 4 week duration dry spell events was observed in almost all the talukas during July compared to other monsoon months in which it was observed in less number of talukas of Buldhana district. The spatial variation of available water holding capacity of the soils in the study area varies from 140 to 200 mm per meter depth in different talukas of Buldhana district.

    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-13) DABRASE, SUMIRAN. S.; Patode, Dr. R. S.
    Hydrological investigation of Kajaleshwar micro watershed was carried out for groundwater development and crop planning. Geospatial Techniques like Remote Sensing (RS) and Geographical Information System (GIS) were used for preparing thematic maps. The research work was undertaken with objectives to prepare the thematic maps of the study area i.e. Kajaleshwar micro watershed, to study the impact assessment of rainwater harvesting structures i.e. CNB’s on groundwater fluctuations and also suggestion of crop planning. Thematic maps including land use/land cover map, soil texture, DEM, and slope maps were generated using RS and GIS technique for the micro watershed. According to the maps generated for the watershed, agriculture area, waste land and built up land was calculated. The soil texture of the watershed was also analyzed. The elevation and slope of the watershed was studied using thematic maps. The observations of wells and CNB’s were monitored and monthly recharge was checked. The aquifer properties i.e. hydraulic conductivity, transmissivity and specific yield were determined. Average hydraulic conductivity of Kajaleshwar micro watershed was 7.83 ×10-4 (m/s), average transmissivity of Kajaleshwar micro watershed was 5.312 × 10-3 (m2/s) and average specific yield of Kajaleshwar micro watershed was 13.33 % were observed for the micro watershed. The runoff of the watershed was calculated by SCS curve number method. The storage capacity of CNB’s was calculated. From the results, it was observed that due to construction of water conservation structures, the water availability was increased and the farmers were benefitted and for the rainfed agriculture areas of the micro watershed crop planning was suggested. The study was therefore helpful in sustainable development of the natural resources of the micro watershed.

    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-26) MAL, NIKUNJ.; Gharde, Dr. K. D.
    Ground water plays an important role in the overall development of any area. The ground water of India has been decreasing with a significant rate since last decade. Hence, the present scenario of ground water development calls for an urgent step for augmenting ground water resources. The remote sensing and GIS is one of the most advance tools for studying groundwater recharge potential of the particular area of interest. Hence, keeping ground water development by artificial recharge In mind, the present study has been taken up with objective of investigation to find out the morphometric properties and probable recharge perceptive zones of Mann river basin of Maharashtra state. In the present study; the factors like geology (lithology), soil texture, drainage density, slope and land use land cover have been used along with Digital Elevation Model (DEM) to determine the morphometric properties and to prepare the ground water recharge potential zone map. The total catchment area of the basin was found out to be 2424.43 sq. km with a perimeter of 345.41 km. The Mann river was found to be a 5th order stream having a total number of 660 streams. The mean stream length of 1st to 5th order streams were 1.3 km, 1.46 km, 6.67 km, 26.52 km and 72.07 km respectively. The stream length ratio of the basin varies from 0.39 to 0.75. The value of bifurcation ratio of the basin varies from 3.04 to 7. The length of overland flow was found to be 0.41 km. The stream frequency and drainage density of the basin was found to be 0.27 number per km2 and 0.82 km/km2 respectively. The texture ratio of the basin was found to be 1.91 and form factor was found to be 0.20. The circulatory ratio and elongation ratio of the basin were found to be 0.26 and 0.51 respectively. The total relief of the basin was found to be 400 m and the relief ratio was found to be 3.64. The ruggedness number of the basin was found to be 0.328. The final ground water recharge potential map was prepared by overlaying five thematic maps namely, geology, slope, LULC, drainage density and soil map using weighted index method. The map was divided into four categories i.e. low, moderate, high and very high potential zones. The area under low groundwater recharge potential is found to be nearly 103.8774 sq. km. The area under moderate groundwater recharge potential was found to be 1855.96 sq. km. and under high recharge potential was 540.871 sq. km. The area under very high recharge potential zone was found to be only 15.59 sq. km.
