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.

    SCREENING OF BLACKGRAM (Vigna mungo L. Hepper) GENOTYPES FOR PHYSIOLOGICAL EFFICIENCY AND DROUGHT TOLERANCE
    (Acharya N.G. Ranga Agricultural University, 2017) YOHAN, Y; SUDHAKAR, P
    The experiment entitled “Screening of Blackgram (Vigna mungo L. Hepper) genotypes for Physiological efficiency and Drought tolerance” was conducted at crop physiology laboratory (Lab study) and dry land farm (Field study), S.V. Agricultural College, Tirupati. Forty five blackgram genotypes obtained from RARS, LAM, ANGARU were screened for heat tolerance using the standardized Thermo Induced Response (TIR) protocol, where seedlings were exposed to gradual and challenging temperatures in environment chamber. Among the 45 genotypes, top ten genotypes (KU-12-55, LBG-623, LBG-680, NDU-12-300, LBG-685, KU-12-14, LBG-645, KU-12-37, TBG-104, KU-12-13) having higher heat tolerance in terms of higher seedling survival and less reduction in root and shoot growth were selected along with two genotypes having lower heat tolerance viz., LBG-752, LBG-20. A field trail was conducted with two irrigation treatments (Control and stress) and 12 blackgram genotypes replicated thrice in split plot design. Moisture stress was created at pod formation stage i.e for a period of 15 days starting from 40 to 60 DAS. Sufficient moisture stress was created among stress treatments leaf relative water content was reduced by 25.2 per cent. xxii Morphological characters like plant height, number of nodules, leaf area, total dry matter, physiological parameters, drought tolerance traits viz., rooting abilities, Water Use Efficiency (WUE), Relative Water Content (RWC), chlorophyll Stability Index (CSI), Proline (Osmoregulant), Super oxide dismutase, Perioxidase (POD) (Antioxidant enzyme) and Nitrate reductase (NR) and yield related parameters were examined. Growth and physiological traits viz. plant height, crop growth rate (CGR), net assimilation rate (NAR), leaf area index (LAI) and leaf area duration (LAD), WUE traits (SLA, SCMR), other drought tolerant traits viz., CSI, RWC, yield and HI significantly reduced under moisture stress conditions compared to irrigated control, where as proline, POD and SOD were increased. The genotypes TBG-104, KU-12-13, KU-12-37 and LBG-623 maintained higher leaf area, dry matter and higher physiological traits viz., CGR, NAR, LAI and LAD compared to other entries under irrigated as well as stress conditions. These genotypes also recorded higher drought tolerance interms of WUE traits i.e moderate SLA and high SCMR, higher chloroplast stability (CSI), higher accumulation of proline and SOD enzyme, which denotes the efficiency of these genotypes in conserving water as well as maintaining osmoregulation and cell membranes integrity under drought condition. Genotypes TBG-104, KU-12-13 and KU-12-37 recorded higher mean root length and low root dry weight and hence maintained higher tissue water content compared to other genotypes. TBG-104, KU-12-13 and KU-12-55 which maintained higher growth, physiological and drought tolerance attributes also recorded higher HI, yield and its components followed by LBG-680, KU-12-37 and LBG-623. The genotype NDU-12-300, KU-12-14 and LBG 645 recorded lower yields under imposed moisture stress conditions as these genotypes recorded lower physiological attributes and drought susceptibility characters. TBG-104, KU-12-13 and KU-12-37 recorded lower percent yield loss in terms of higher drought tolerance index. The genotypes TBG-104, KU-12-13 and KU-12-55 were superior in terms of physiological efficiency, heat and moisture stress tolerance with high seed yield. These genotypes can be fit in rainfed cultivation or can be used as donor source for development of drought tolerant blackgram genotypes through conventional as well as molecular breeding

    INFLUENCE OF WATER LOGGING ON CERTAIN PHYSIOLOGICAL AND BIOCHEMICAL CHARCTERS OF PIGEONPEA (Cajanus cajan (L.) Millsp)
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) YOHAN, Y; UMAMAHESH, V
    Laboratory and pot culture experiments were conducted at P.G Laboratory, Department of Crop Physiology, S.V. Agricultural College, Tirupati and at RARS, Tirupati during Kharif, 2013-2014. The laboratory experiment was conducted in a Completely Randomized design with 17 red gram genotypes. There were five treatments with four replications. Three genotypes were selected based on their performance evaluated through germination percentage, vigor index and electrical conductivity .Germination percentage and vigor index of LRG-30 was 76.25% and 60.81 respectively. Besides LRG-30, Maruti and Asha were the other genotypes used to evaluate the sensitive stage of redgram crop to waterlogging through a pot culture experiment. Experimental layout for pot culture was in split plot design. Three main stress imposing stages viz., 40 DAS, 80 DAS and 120 DAS were taken as main plots and three genotypes (LRG 30 (Palanadu), ICPL 8863 (Maruti) and ICPL 87119 (Asha)) were taken as sub plots. All the morphological and physiological characters used for evaluation of Pigeonpea genotypes under waterlogged conditions viz., plant height, number of primary branches, leaf area, total dry matter, leaf dry matter, root dry matter, SLA, SLW, CGR, LAI varied significantly among waterlogging treatments and genotypes at all stages of crop growth. Biochemical characters viz., SPAD chlorophyll meter reading (chlorophyll content), total sugars, reducing sugars and super oxide dismutase enzyme content varied significantly at all the stages of stress imposition viz., 40DAS, 80DAS, 120DAS. Anatomical character in terms of aerenchyma formation was also varied among the genotypes as a response to hypoxia. The average percentage decrease over before imposing stress three genotypes at three different crop growth stages with respect to leaf area, root dry weight and LAI was 66.73, 42.12 and 66.13, where as the same values for chlorophyll content, total sugars, reducing sugars and superoxide dismutase content were record 38.07, 28.47, 48.66 and 36.40. The results showed that the number of pods per plant seems to be the major yield component affected seed yield under stress. Among the crop growth stages pod development stage was the most sensitive stage as for as final yield is concerned. Among the genotypes LRG-30 proved superior in majority of physiological and biochemical characters compared to Asha and Maruti. Higher seed yield was also observed in LRG 30 (27.51 g plant-1) followed by Asha (26.70 g plant-1) and Maruti (13.57 g plant-1). Water logging at 40DAS affected plant height and crop growth rate. When stress was imposed at 80DAS number of primary branches, leaf area, SLA, LAI and SLW were affected. A greater decrease in leaf area, total dry matter, leaf dry weight and root dry weight was observed when stress was imposed at 120 DAS. The present study forms a physiological basis to understand the sensitive stage of redgram to waterlogging stress.
