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.

    CHARACTERIZATION, CLASSIFICATION AND EVALUATION OF GROUNDNUT GROWING SOILS OF SRIKALAHASTI DIVISION IN CHITTOOR DISTRICT FOR SUSTAINABLE LAND USE PLANNING
    (Acharya N.G. Ranga Agricultural University, 2017) NAGARJUNA, V; NAIDU, M.V.S.
    The present investigation involves "Characterization, classification and evaluation of groundnut growing soils of Srikalahasti division in Chittoor district, Andhra Pradesh for sustainable land use planning". For this, twenty typical pedons from groundnut growing areas were studied for physical, physico-chemical, chemical properties and mineralogy. The area is characterized by semi-arid monsoonic climate with distinct summer, winter and rainy seasons. The pedons occurs in plains (P1, P2, P4, P5, P6 and P8), very gently sloping (P3, P7, P9, P10, P11, P12, P13, P14, P15, P16 and P17) and gently sloping (P18, P19 and P20) topography. The P4, P6, P14 and P16 were developed from alluvium parent material while P1, P2, P3, P5, P7, P8, P9, P10, P11, P12, P13, P15, P17, P18, P19 and P20 were originated from granite-gneiss. The morphological features indicated the presence of AC (P4, P6, P11, P13, P14, P17, P18, P19 and P20), A-(Bw)-C (P1, P3, P7, P8, P9, P10, P15 and P16) and A-(Bt)-C (P2, P5 and P12) profiles. The soils were deep to very deep in depth (expect P11), very light pale brown to very dark brown in colour, sand to sandy clay in texture (in the horizons of different pedons) and had varied structure including crumb, sub-angular blocky, angular blocky and single grain. xv The clay content in P11 and P18 exhibited almost a decreasing trend with depth whereas P1 and P12 showed an increasing trend with depth. However, no specific trend with depth was observed in remaining pedons. Physical constants like water holding capacity, loss on ignition and volume expansion followed the trend of clay content. All the pedons exhibited an irregular trend of bulk density with depth. The groundnut growing soils were moderately acidic to strongly alkaline (5.54 to 8.16) in reaction, non-saline (0.01 to 0.09) and low to medium (0.06 to 0.74 %) in organic carbon. These soils had CaCO3 ranging from 2.40 to 3.23 per cent. The CEC varied from 8.02 to 46.26 cmol (p+) kg-1 and exchange complex was dominated by Ca+2 followed by Mg+2, Na+ and K+ . Chemical composition of soils revealed that all the pedons registered higher silica content indicating siliceous nature. The soils were low to medium (19.20 to 247.60 mg kg-1 ) in available nitrogen, low to high (4.10 to 21.67 mg kg-1 ) in available phosphorus and potassium (30.23 to 408.14 mg kg-1 ) and deficient to sufficient in available sulphur (5.58 to 47.99 mg kg-1 ). The soils were sufficient in available Fe, Cu and Mn. However, available Zn was sufficient in surface horizons and deficient in sub-surface horizons in all pedons expect P13, P15 and P18 wherein it was found to be sufficient. Based on CEC / clay ratio, X-ray diffraction analysis, physical, chemical and physico-chemical properties, it is concluded that the mineralogy class for P1, P3, P7, P8, P9, P10, P14 and P16 was smectitic whereas, mineralogy class for P2, P5 and P12 was kaolinitic. However, P4, P6, P11, P13, P17, P18, P19 and P20 have more silica (>80), hence the mineralogy class for these pedons was siliceous. Based on the morphological, physical, physico-chemical, mineralogical and meteorological data, the groundnut growing soils in Srikalahasti division of Chittoor district were classified as: Fine-loamy, smectitic, isohyperthermic, Typic Haplustepts (P1, P8, P9 and P10); Coarse-loamy, kaolinitic, isohyperthermic, Typic Haplustalfs (P2); Coarse-loamy, smectitic, isohyperthermic, Typic Haplustepts (P3 and P15); Sandy, siliceous, isohyperthermic, Typic Ustifluvents (P4); Fine-loamy, kaolinitic, isohyperthermic, Typic Haplustalfs (P5 and P12); Sandy, siliceous, isohyperthermic, Typic Ustipsamments (P6); Fine-loamy, smectitic, isohyperthermic, Vertic Haplustepts (P7); Coarseloamy, siliceous, isohyperthermic, Lithic Ustorthents (P11); Fine-loamy, siliceous, isohyperthermic, Typic Ustrorthents (P13); Fine-loamy, smectitic, isohyperthermic, Fulventic Haplustepts (P14 and P16); Coarse-loamy, siliceous, isohyperthermic, Typic Ustrorthents (P17, P18 and P20) and Sandy, siliceous, isohyperthermic, Lithic Ustrorthents (P19). xvi Based on climate, site and soil characteristics, the groundnut growing soils of Srikalahasti division of Chittoor district were classified into land capability classes and sub-classes viz., IIIs (P1, P2, P3, P4, P5, P6, P8, P9, P14 and P15), IIIes (P18), IVs (P10, P13, P16 and P17), IVes (P7, P12 and P20) and VIes (P11 and P19). The soil-site suitability evaluation of groundnut growing soils of Srikalhasti division indicated that P2, P3, P4 P5, P7, P10, P13, P14, P16 and P17 were suitable (S1), P1, P6, P8, P12, P15, P18 and P20 were moderately suitable (S2 – constraints of soil pH, organic carbon and soil depth) and P9, P11 and P19 were marginally suitable (S3 – constraints of soil pH, organic carbon and soil depth) for growing groundnut crop. Production potential of groundnut growing soils of Srikalahasti division revealed that P1, P2, P3, P5, P6, P7, P8, P9, P10, P12, P13, P14, P15, P16, P17 and P18 of were grouped under the good productivity class while P4, P11, P19 and P20 were classified under average class. The coefficient of improvement (Ci) varied from 1.23 to 2.61 indicating the implementation of judicious soil and water management practices to sustain crop productivity. Groundnut index leaf samples were severely deficient in leaf N, severely deficient to deficient in leaf P, adequate in leaf K, S, Fe, Cu and Mn and marginally adequate to adequate in leaf Zn.
