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.

Kothari, Chairman of the University Grants Commission stressed the need for establishing at least one Agricultural University in each Indian State... 23, June 1966: Inauguration of the Administrative building of the university by Late Smt. Indira Gandhi, the then Hon`ble Prime Minister of India... July, 1966: Transfer of 41 Agricultural Research Stations, functioning under the Department of Agriculture... May, 1967: Transfer of Four Research Stations of the Animal Husbandry Department... 7th November 1996: Renaming of University as Acharya N. G. Ranga Agricultural University in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga... 15th July 2005: Establishment of Sri Venkateswara Veterinary University (SVVU) bifurcating ANGRAU by Act 18 of 2005... 26th June 2007: Establishment of Andhra Pradesh Horticultural University (APHU) bifurcating ANGRAU by the Act 30 of 2007... 2nd June 2014 As per the Andhra Pradesh Reorganization Act 2014, ANGRAU is now... serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication...

    RESPONSE OF AEROBIC RICE ZERO TILLAGE MAIZE CROPPING SYSTEM TO SUB SURFACE DRIP FERTIGATION
    (Acharya N.G. Ranga Agricultural University, Guntur, 2016) PRASADA RAO, V; VENKATESWARLU, BALINENI
    A field experiment was carried out for two consecutive years (2012-13 and 2013-14) on a sandy loam soil of Jain Hi-Tech Agri Institute, Jalgaon, Maharashtra with an objective to study the response of aerobic rice-zero tillage maize cropping system to sub surface drip ferigation. The experiment was laid out in a split-plot design with four replications. Four irrigation schedules were taken as main plots and four nitrogen levels in sub plots in drip system for both rice and maize crops. Irrigation schedules for rice included I1: Sub surface drip irrigation (SDI) at 100% pan evaporation (Epan), I2: SDI at 125% Epan, I3: SDI at 150% Epan and I4: at 175% Epan with four nitrogen levels viz., N1: 90; N2: 120; N3:150; and N4:180 kg ha-1 through fertigation. For the subsequent maize crop irrigation treatments included I1: SDI at 75% Epan, I2: SDI at 100% Epan, I3: SDI at 125% Epan and I4: SDI at 150% Epan with four nitrogen levels i.e., N1:120; N2: 160; N3:200 and N4:240 kg ha-1 through fertigation. Outside the layout of the main experiment, two checks and one check were tested in rice and maize crops, respectively. The checks for rice crop included, check 1: Aerobic rice non-irrigated with 120 kg N ha-1, check 2: Aerobic rice with supplemental irrigation at IW/CPE ratio of 1.5 with 120 kg N ha-1 In maize crop, the check tested was surface irrigation at IW/CPE ratio of 1.2 with 160 kg N ha-1. The cultivars used for the study were ‘25P25’ (Pioneer Hybrid) and ‘Dekalb’ (Private hybrid) and maize (DKC-8101) crops, respectively. Growth parameters, yield attributes, yield, nitrogen uptake, water productivity, nitrogen use efficiency and economics of aerobic rice and zero tillage maize were influenced by irrigation schedules and nitrogen levels through fertigation. Plant height and tillers m -2 and drymatter production of aerobic rice were significantly higher in 175% Epan schedule compared to that of 100% Epan but comparable with that of 150% Epan. The number of panicles m-2 and filled spikelets panicle-1 increased from 100% Epan to 175% Epan while sterility of spikelets was higher with 100% Epan schedule. Higher grain and straw yield, nitrogen uptake, and economics were recorded with 175% Epan over the other three schedules. Irrespective of the irrigation schedules, growth parameters (plant height, tillers m-2 and drymatter accumulation), yield attributes (panicles m-2 and filled spikelets panicle-1) increased with level of N application from 90 to 180 kg N ha-1. The number of days taken to flowering was significantly lower with 180 kg N ha-1 while, sterility of spikelets was higher at 90 kg N ha-1compared to other doses. Grain yield, straw yield, nitrogen uptake and economic parameters were higher at 180 kg N ha-1. In general, growth parameters (plant height, drymatter accumulation) yield attributes (cobs plant-1, kernels cob-1, kernel weight cob-1) kernel yield, stover yield and nitrogen uptake of zero till maize increased with increase in irrigation schedule from 75% Epan to 150% Epan irrigation schedule in drip irrigation. Tasseling and silking was hastened in 150% Epan schedule compared to 75% Epan. Increase in the level of N application from 120 to 240 kg N ha-1 resulted in the increase of all the growth parameters, yield attributes, kernel yield, stover yield and nitrogen uptake. The economic indicators (gross returns, net returns and returns per rupee of investment) were higher with the irrigation schedule of 150% Epan and nitrogen dose of 240 kg N ha-1 applied through fertigation. Productivity of cropping system in terms of rice equivalent yield was the highest with the irrigation schedule of 175% Epan and 150% Epan and with the application of 180 and 240 kg N ha-1 to rice and maize crops respectively grown in the sequence. Water requirement increased with the increase in water input while, its productivity reduced correspondingly in both rice and maize crops and the cropping system as a whole. However, nitrogen use efficiency enhanced with the increase in water input and reduced with increase in the N level. The investigations conducted for two consecutive years, clearly indicated the benefit of fertigation at 175% Epan with 180 kg N ha-1 to rice and 100% Epan with 240 kg N ha-1 to maize crops in increasing the productivity and profitability of aerobic rice - zero tillage maize cropping system.
