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.

    DYNAMICS OF SOIL POTASSIUM UNDER DIFFERENT CROPPING SYSTEMS IN SOUTHERN ZONE OF A.P.
    (ACHARYA N G RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2019) CHARANKUMAR, G.R.; MUNASWAMY, V
    Present investigation was carried out to study “Dynamics of soil potassium under different cropping systems in Southern Zone of A.P.” Soil samples were collected from five locations in prominent cropping systems at 0-15 cm and 15-30 cm depth from three districts of Southern Zone of Andhra Pradesh. The soils of study area were light in texture and ranged from sandy loam to clay. Soils of Chittoor district were acidic to alkaline in reaction, while soils of Y.S.R Kadapa and S.P.S.R Nellore district were near neutral to alkaline in nature. Soils from three districts were non-saline with respect to soluble salt content. In Chittoor district, the highest available K was recorded under groundnut + redgram intercropping system (139.30 mg kg-1) in surface soils, while in subsurface soils under groundnut monocropping system (100.70 mg kg-1). Highest water soluble K in surface soils was recorded under bajra-groundnut cropping system (41.20 mg kg-1), while in sub-surface soils under groundnut + redgram intercropping system (25.85 mg kg-1). Highest exchangeable K was recorded under groundnut monocropping system in surface soils (111.80 mg kg-1) and subsurface soils (81.20 mg kg-1). Highest non-exchangeable K in surface soils was recorded under paddy-groundnut cropping system (581.55 mg kg-1), while in sub-surface under bajra-groundnut cropping system (495.90 mg kg-1). Highest mean lattice K and total K were recorded under redgram monocropping system in surface soils (42529.80 mg kg-1 and 42990 mg kg-1, respectively), while in sub-surface soils under groundnut+redgram intercropping system (38496.60 mg kg-1 and 38970 mg kg-1, respectively). xiii In Y.S.R Kadapa district, highest available K was recorded under paddypaddy cropping sequence at both surface (282.80 mg kg-1) and sub-surface soils (160.90 mg kg-1). Highest water soluble K was recorded under groundnutgroundnut cropping sequence at both surface (43.30 mg kg-1) and sub-surface (17.25 mg kg-1) layers. Highest exchangeable K was recorded under paddy-paddy cropping sequence in both surface (254.10 mg kg-1) and sub-surface (144.05 mg kg-1) layers. Highest non-exchangeable K was recorded under fallowbengalgram cropping sequence (970.35 mg kg-1) in surface soils, while in subsurface soils under paddy-paddy cropping sequence (623.00 mg kg-1). Highest lattice K and total K were recorded under groundnut-groundnut cropping sequence (23326.60 mg kg-1 and 24190 mg kg-1, respectively) in surface soils, while in sub-surface soils under groundnut monocropping sequence (35828.20 mg kg-1 and 33330 mg kg-1, respectively). In S.P.S.R Nellore district, highest available K was under groundnutpaddy cropping sequence (278.85 mg kg-1) in surface soils, while in sub-surface soils under fallow-blackgram cropping sequence (175.50 mg kg-1). Highest water soluble K was recorded under paddy-paddy cropping sequence both in surface (38.35 mg kg-1) and sub-surface soils (28.15 mg kg-1). Highest exchangeable K was recorded under groundnut-paddy cropping sequence (256.05 mg kg-1) in surface soils, while in sub-surface soils under fallow-blackgram cropping sequence (161.50 mg kg-1). Highest non-exchangeable K was recorded under groundnut-paddy cropping sequence at both surface (672.95 mg kg-1) and subsurface soils (696.30 mg kg-1). Highest lattice K and total K were recorded under paddy-paddy cropping sequence at both surface (33370.60 mg kg-1 and 33950 mg kg-1, respectively) and sub-surface soils (20383.50 mg kg-1 and 20910 mg kg-1, respectively). In Chittoor district, available K of surface soils was highly and significantly correlated with water soluble K (r = 0.779**), exchangeable K (r = 0.963**) and non-exchangeable K (r = 0.837**). In sub-surface soils available K was highly and significantly correlated with water soluble K (r = 0.541**) and exchangeable K (r = 0.963**). In Y.S.R Kadapa district, available K of surface soils was highly and significantly correlated with exchangeable K (r = 0.987**) and nonexchangeable K (r = 0.791**). In sub-surface soils available K was highly and significantly correlated with exchangeable K (r = 0.766**) and nonexchangeable K (r = 0.943**). In S.P.S.R Nellore district, available K of surface soils was highly and significantly correlated with exchangeable K (r = 0.990**) and nonexchangeable K (r = 0.875**). In sub-surface soils available K was highly and significantly correlated with exchangeable K (r = 0.982**). In all the three districts high degree of correlation was observed among lattice K and total K at both surface and sub-surface soils.
