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.

    Title: ASSESSMENT OF IRRIGATION WATER AND ITS EFFECT ON SOIL PROPERTIES IN TELHARA AND NANDURA TEHSILS OF PURNA VALLEY.
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-09-15) Authors: AKHADE, SHUBHAM HANUMANT.; Advisor: Konde, Dr. N. M.
    Abstract: The present investigation entitled “Assessment of irrigation water and its effect on soil properties in Telhara and Nandura tehsils of Purna valley” was undertaken during 2020-2021 at Department of Soil Science and Agricultural Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra. The investigation was carried out to assess the quality of irrigation water in Purna tract and to study the soil characteristics of irrigated area in Telhara and Nandura tehsil. Twenty water samples from borewells were collected in post monsoon season (winter). Similarly, twenty respective soil samples were also collected from the respective field irrigated with borewell from villages viz. Dapura, Bhamberi, Khaparkhed, Thar, Dahigaon, Manatri BK, Adsul, Talegaon Paturda from Telhara tehsil of Akola disrict and Nimgaon, Dadgaon, Hingna, Narkhed, Zadegaon, Yerali, Belad, Alampur, Pathonda, Parsoda from Nandura tehsil of Buldhana District. Based on the data generated, it was observed that, the quality of irrigation water in Purna valley is having high salinity and medium sodium hazard (C3S2) during post monsoon (winter) season. Amongst the cation sodium was dominant in water samples. The anionic composition was within the permissible limit, except bicarbonates which was dominant amongst anions and beyond the permissible limit. The sodium adsorption ratio was close to the permissible limit and Mg:Ca ratio of all water samples during post monsoon (winter) season found to be disturbed. The adjusted sodium adsorption ratio was above the permissible limit. As per Kelley’s ratio most of the water samples were above the limit. On the basis of permeability index irrigation water was categorized in class II and III. The residual sodium bicarbonate of water collected from borewell were above permissible limit. Whereas the soluble sodium percentage of the irrigation water were found above permissible limit. The magnesium adsorption ratio was lower than the permissible range. The collected soil samples were analyzed for soluble cations and anions in soils and it was observed that, the soils were highly saline. Amongst the cation’s sodium was dominant followed by Ca2+ > Mg2+ > K+. The pHs and ECe of soils irrigated with borewell was comparatively higher than the normal range. The concentration of soluble K+ was very less in the borewell. While, among the anion HCO-3 > SO42- > Cl- were dominant in borewell as compared to normal range. The soil properties were highly influenced due to application of borewell water during irrigation. The fertility parameters viz, available nitrogen, phosphorus and potassium were numerically changed after irrigation. The continuous irrigation with borewell water found to be measurable in declining available nitrogen in the soil. Similarly, the available phosphorus and available potassium also decreased due to borewell irrigation water. The significant change in concentration of exchangeable cations in soils were observed due to continuous application of borewell water. Exceptionally the sodium content in soil increased due to high sodic water of borewell. The cation exchange capacity and hydraulic conductivity of the soils irrigated with borewell was lower. The bulk density of soils irrigated with borewell water was found to be high while the MWD was found to be lower. The calcium carbonate content of soils irrigated with borewell water was higher however, organic carbon was declined. The overall result exhibited that, the water collected from borewell have shown adverse effect on soil properties. The consistent use of the borewell water can create unfavorable environment beneath the soil. This can ultimately be hazardous for sustainable crop production. Therefore, while irrigating the crops, it is advisable to use other sources for irrigation, or borewell water can be used along with blending of other sources and with precautions. Similarly best management practices need to be amalgamated with advance irrigation methods.
