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.

    QUANTIFICATION OF AGRO ECOSYSTEMS HEALTH IN MAIZE GROWING TRACTS OF GUNTUR DISTRICT RECEIVING SEWAGE WATER IRRIGATION
    (Acharya N G Ranga Agricultural University, 2023-12-02) APPICHI KAVITHA; V. VISALAKSHMI
    A field survey based study was conducted entitled “Quantification of Agroecosystems Health in Maize growing tracts of Guntur District receiving sewage water irrigation” was undertaken at the Department of Soil Science, Agricultural college Bapatla, ANGRAU during Rabi 2021-22 to assess the impact of untreated sewage water and ground water on soil and maize crop. Twenty five locations were selected in Chebrolu to observe the effect of sewage water irrigation on physical, chemical and biological properties of soils in comparison to the ground water irrigation. The four sewage irrigated villages selected under study were Suddapalle, Vejendla, Selapadu, and Sekuru and three ground water irrigated villages were Thotapalem, Vetapalem and Tsunduru. The sewage as well as ground water quality was tested. The soil samples were collected at pre-sowing stage and harvest stage of maize crop from sewage irrigated fields and ground water irrigated fields of 25 locations separately. Sewage water and ground water samples collected from 25 locations in the month of February, 2022 during post-monsoon season. Maize samples (Root, Stalk and Grain) were collected from same locations at the time of harvest. Physico-chemical and chemical characteristics of the collected sewage water, soil, ground water and maize samples were analysed. The pH and Electrical Conductivity of untreated sewage water used for irrigation in peri- urban areas of Guntur district ranged from 7.57 to 8.60 and 1.23 to 2.30 where as in ground water varied from 6.30 to 7.30 and 0.45 to 1.70 dSm-1 respectively indicating that the sewage water is alkaline, marginally saline in nature. Carbonates, bicarbonates, sulphates, chlorides, sodium, potassium, calcium and magnesium concentrations ranged from0.4 to 1.4, 9.2 to 13.4, 1.37 to 2.23, 4.08 to 6.40, 5.40 to 8.20, 0.6 to 1.5, 3.30 to 5.00 and 1.73 to 2.90 where as in ground water 0.1 to 0.5, 1.00 to 1.90, 0.04 to 0.5, 0.50 to 2.30, 0.8 to 2.3, 0.01 to 0.5, 1.12 to 1.96 and 0.2 to 1.10 me L-1 respectively.

VISALAKSHMI University : ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY Year of submission : 2022 xv Residual Sodium Carbonate content in sewage water were in the range of 2.70 to 4.10 and 4.1 to 7.00 where as in ground water 0.40 to1.15 and 0.36 to 1.96 me l-1 respectively. Total Dissolved solids (TDS), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in sewage water ranged from 844 to 1472, 110 to 152 mg L-1 and 195 to 245 where as in ground water 288 to 1088, 35 to 89 and 92 to 180 mg L-1 respectively. The micronutrients Iron, Copper, Zinc and Manganese of sewage water ranged from 6.93 to 9.62, 1.12 to 1.93, 2.14 to 4.20 and 2.93 to 5.76 where as in ground water 0.01 to 0.08, 0.02 to 0.08, 0.02 to 0.08 and 0.01 to 0.08 mg L-1 respectively. It indicates that sewage water have more micronutrients compared to ground water. Heavy metals Chromium, Cobalt, Nickel, Cadmium and Lead of sewage water ranged from 0.1 to 0.3, 0.003 to 0.38, 0.02 to 0.12, 0.01 to 0.018 and 0.21 to 0.62 where as in ground water 0.002 to 0.008, 0.01 to 0.04, 0.01 to 0.05, 0.012 to 0.018 and 0.21 to 0.48 mg L-1 respectively The pH and Electrical Conductivity in soils irrigated with sewage water ranged from 7.40 to 7.78 and 0.55 to 0.82 dSm-1 at pre-sowing stage whereas from 7.73 to 7.92 and 0.43 to 1.23dS m-1 at harvest stage respectively. The pH and Electrical Conductivity in soils irrigated with ground water ranged from 7.10 to 7.42 and 0.43 to 1.20 dSm-1 at pre-sowing stage whereas from 7.00 to 7.20 and 0.83 to 1.23dS m-1 at harvest stage respectively. The per cent organic carbon content of soil irrigated with sewage water ranged from 0.70 to 0.92% during pre-sowing stage and 0.79 to 0.95% at harvest stage. Available Nitrogen, Phosphorus, Potassium, Sulphur, Calcium and Magnesium were high in sewage irrigated soils than that of ground water irrigated soils at both stages. The DTPA extractable Zinc, Iron, Copper and Manganese content in sewage irrigated soils ranged from 0.42 to 1.09, 4.10 to 8.60, 1.57 to 5.24 and 1.76 to 4.95 mg l-1 respectively at pre-sowing stage and 0.54 to 1.52, 4.85 to 9.89, 2.99 to 6.47 and 2.49 to 5.61 mg l-1 respectively at harvest stage. Low micronutrient content in ground water irrigated soils at both stages. The Cadmium, Chromium, Nickel and Lead content were higher in sewage irrigated soils than the ground water irrigated soils. In fact, the concentration of the heavy metals increased during the study period (from pre-sowing to Harvest stage). Macro and micronutrient properties of root, stalk and grain of maize crop sufficient with sewage irrigation. Heavy toxic metals in general are poorly translocated and are usually accumulated in roots. The micronutrient and toxic heavy metals uptake by maize plant sample at harvest revealed that these metal ions are taken up by plant and in general are more than what is observed in normal plant. However, the plants analysed in the present study heavy metal contents are below the permissible limits, and did not exhibit reduced yields compared to groundwater irrigation.
