Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    STUDIES ON THE INFLUENCE OF SEWAGE IRRIGATION WATER ON THE PROPERTIES OF RICE GROWING SOILS
    (Acharya N.G. Ranga Agricultural University, Guntur, 2021-12-07) . ANJANI CHOWDARY, B; SREENIVASA CHARI, Dr. M.
    ar of submission : 2020 Investigations were carried out to characterize the sewage water, ground water and its suitability for irrigation in Pathakadapa area of YSR Kadapa district and effect of sewage water irrigation (>20Years) on soil physical, chemical and biological properties. The sewage water and ground water samples collected at periodical intervals from Pathakadapa area in four radiant directions during summer (April – June) and winter (October to December) were analyzed for various constituents and its suitability for irrigation was assessed. Profile pits four in number were opened in the area receiving the sewage water continuously for 20 years. Their morphological and pedon characteristics were studied. Horizon wise soil samples were collected and analyzed for various Physico-chemical and biological properties. Surface soil samples were also collected in study area and were analyzed. Rice straw samples were collected at harvest in four radiant directions and analyzed for chemical constituents. Adsorption column studies were conducted to evaluate the effectiveness of soil, biochar and rice husk ash for removal of heavy metals present in the sewage water. The study was also looked into the effectiveness of column heights and particle size of adsorbents in pollutants removal and the data was subjected to statistical scrutiny. The salient findings of the investigation are summarized below. Sewage water collected in different time periods was dark in colour with appreciable quantities of suspended and dissolved solids with high values of BOD and COD. The sewage effluent had alkaline pH and high EC with appreciable quantities of Cl-1 , SO4 2- , CO3 2- , HCO3 - , Na+ , K+ , Ca2+ and Mg2+ and variable amounts of heavy metals. A marked seasonal variation in composition of sewage water was observed and further, with distance from the source the constituents were decreased in all the directions. Sewage water registered heavy metals Cu, Mn, Cd, Pb and Ag above the permissible limits of FAO, (1985). The sewage water fell under the category of C4S1 as per the USSL classification. The ground water showed alkaline pH and high EC with appreciable quantities of Cl-1 , SO4 2- , CO3 2- , HCO3 - , Na+ , Ca2+ and Mg2+. Further, it was observed that the concentration of Na+ , Cl-1 and NO3 - were higher in ground water than in sewage water. Ground water registered notable amounts of heavy metal and categorized as C4S1. The sewage water irrigation markedly increased the apparent specific gravity, pH, EC, available NPK, organic carbon, CEC, exchangeable cations and heavy metals viz., Zn, Cu, Fe, Mn, Cd, Pb and Ag of the pedon which are receiving sewage effluent for over 20 years. Further, with depth the values were decreased. Increased population of bacteria, fungi and actinomycetes was observed due to sewage water irrigation. Further, actinomycetes population increased with depth. The surface soil samples analyzed data reveals that pH, EC, available NPK, organic carbon, CEC, exchangeable cations and heavy metals values were high up to 1.0 km radius from the source point and in general with distance the values were decreased. The soil quality index developed for the study area recorded as 0.67, which falls under the category of “moderate”. Sewage water irrigation increased the concentration of Phosphorous and potassium in rice straw. Though the heavy metal concentration was recorded below the permissible limits, bioaccumulation of iron, lead, cadmium and Ag was noticed. Adsorption column studies demonstrated that biochar is effective in sorption of heavy metals from sewage water and further the sorption was increased with decrease in the particle size. With increase in contact time upto 120 minutes the sorption was increased while for Cu, Cd and Ag the equilibration was attained at 240 minutes. The perusal of the data on the sewage water shows alkaline pH, high EC, high exchangeable sodium and heavy metal load which limits its usage as irrigation water. Further, bioaccumulation and soil quality index are quite alarming to use sewage water for irrigating rice crop in the study area.
