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.

    EFFECT OF IRRIGATION WITH SALINE WATER ON OKRA [Abelmoschus Esculentus (L.) Moench] UNDER DRIP SYSTEM
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) ARULSELVI, A; Er. R. GANESH BABU
    A field experiment “Effect of irrigation with saline water on okra (Abelmoschus Esculentus (L). Moench) under drip system” was conducted at College of Agricultural Engineering, Bapatla during 2015. The experiment was laid out in Split plot design with 4 main treatments and 3 sub treatments replicated thrice. The treatment comprised of M1S1- Fresh water(0.42 dS m-1) +100 % CWR; M1S2- Fresh water(0.42 dS m-1) + 80% CWR; M1S3- Fresh water (0.42 dS m-1) +60% CWR; M2S1-Saline water (2 dS m-1+100% CWR); M2S2-Saline water (2 dS m-1+80% CWR);, M2S3-Saline water (2 dS m-1+60% CWR);, M3S1-Saline water (4 dS m-1+100% CWR); M3S2-Saline water (4 dS m-1+80% CWR); M3S3-Saline water (4 dS m-1+60% CWR); M4S1-Saline water (6 dS m-1+100% CWR); M4S2-Saline water (2 dS m-1+80% CWR) and M4S3-Saline water (6 dS m-1+60% CWR). The influence of main treatments on physical and chemical properties of soil was determined by standard procedures. The crop water requirement of the okra was calculated as 460.4 mm using CROPWAT model developed by FAO. The climate data of previous year in the experimental area was considered for CWR estimation. The moisture distribution and salt distribution were studied before and after the experiment in the experimental area. It was concluded from the soil moisture distribution study that the water retention in the soil upper layer was increased with increase in salinity of irrigation water applied and salt accumulation was increased with increase in depth in all the treatment plot irrigated with saline water. The hydraulic performance of drip irrigation system was evaluated and it was found that significant effect on emission uniformity of the system was because of saline water. The yield and yield parameters were analyzed and it was found that the significant effect of saline water is found on yield and yield parameters because of both salinity and irrigation quantity. The highest yield was recorded in the treatment irrigated with fresh water at 100 % of CWR as 6.35 t ha-1 and the lowest yield was recorded in the treatment irrigated with saline water of 6 dS m-1 at 60 % of CWR as 2.08 t ha-1. The significant increase in yield of 17.4 % was observed under drip system as compared to the control treatment irrigated by conventional irrigation practice. The threshold salinity level of irrigation water using drip irrigation method in sandy soil to get 90 %, 75 % and 50 % yields of okra are 1.68 dS m-1, 3.04 dS m-1 and 5.04 dS m-1. The influence of various treatments on water use efficiency was analyzed and it was found that the highest water use efficiency was achieved by the treatment irrigated with fresh water at 60 % of CWR. Considerable amount of water saving was achieved by the crop irrigated with 60 % of CWR under drip system.
