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.

    GENESIS, CLASSIFICATION AND EVALUATION OF SOILS IN CHENNUR MANDAL OF KADAPA DISTRICT, ANDHRA PRADESH
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) SREEDHAR REDDY, K; NAIDU, M.V.S.
    The present investigation involves study of genesis, classification and evaluation of soils in Chennur mandal of Kadapa district, Andhra Pradesh. For this, eight representative pedons were selected in eight different locations of the study area covering all types of soils. All the eight pedons were described for their morphological features in the field and horizonwise samples were collected and analyzed in the laboratory for physical, physico-chemical and chemical properties. The study area was characterized by semi-arid monsoonic climate with distinct summer, winter and rainy seasons. The pedons selected were located on plains, very gently sloping and gently sloping topography. Pedon 1was developed from limestone whereas remaining pedons were developed from weathered gneiss. The morphological features indicated the presence of AC or AR (Pedons 1, 2 and 6) and ABC (Pedons 3, 4, 5, 7 and 8) profiles. The soils were shallow to very deep in depth, very dark grayish brown to dark brown in colour, sandy clay loam to clay in texture and had sub-angular blocky, angular blocky and crumb structure. The clay content decreased with depth in pedons1and 7. Pedons 3, 4, 6 and 7 showed no specific trend with depth. Physical constants like water holding capacity, loss on ignition and xv volume expansion followed the trend of clay content. All pedons exhibited an irregular trend of bulk density with depth, corresponding to decreasing organic carbon content with depth. The pedons were slightly alkaline to alkaline in reaction, non-saline and low to medium in organic carbon. All the pedons registered medium to high CaCO3 status. CEC values were low to medium and exchange complex was dominated by Ca+2 followed by Mg+2, Na+ and K+. Chemical composition of soils revealed that all the pedons had high silica content indicating siliceous nature. Regarding nutrient status, the soils were low to medium in available nitrogen, medium to high in available phosphorus, low to high in available potassium and high in available sulphur. However, soils were deficient in available iron and sufficient in available zinc (except in pedon 4 and subsurface horizons of pedon 3), copper and manganese. Based on morphological, physical, physico-chemical, mineralogical and meteorological data, the soils of Chennur mandal were classified as: Pedon 1: Fine, siliceous, isohyperthermic Lithic Ustorthent Pedon 2: Fine-loamy, siliceous, isohyperthermic Typic Ustorthent Pedon 3: Fine-loamy,smectitic, isohyperthermic Typic Haplustept Pedon 4: Fine,smectitic, isohyperthermicVertic Haplustept Pedon 5: Fine-loamy, smectitic, isohyperthermic Typic Haplustept Pedon 6: Fine-loamy,siliceous,isohyperthermic Typic Ustifluvent Pedon 7: Fine,smectitic,isohyperthermic Typic Haplustept Pedon 8: Fine,smectitic, isohyperthermic Vertic Haplustept Based on the soil properties, the soils of the Chennur mandal have been classified into land capability classes and sub-classes viz., IIw (Pedon 5), IIs (Pedon 8), IIIs (Pedon 1), IIIse (Pedons 2, 4 and 6), IIIwe (Pedon 3), IVew (Pedons 7). The soil-site suitability evaluation of study area revealed that pedons1, 2 and 6 were marginally suitable (S3) for rice and temporarily not suitable (N1) for groundnut and bajra, pedons 3 and 7 were marginally suitable (S3) for rice and bajra and temporarily not suitable (N1) for groundnut, pedons 4 and 8 were marginally suitable (S3) for rice, groundnut andbajra, pedon 5 was temporarily not suitable (N1) for rice, groundnut and bajra and pedon 6 was marginally suitable (S3) for rice and temporarily not suitable (N1) for groundnut and bajra.
