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 SEED PRE - TREATMENT AND FOLIAR APPLICATION OF ZINC ON GROWTH, PHYSIOLOGICAL PARAMETERS AND YIELD OF MUNGBEAN (Vigna radiata L.) UNDER WATER STRESS
    (Acharya N.G. Ranga Agricultural University, 2018) BATHULA, SRIKANTH; JAYALALITHA, K
    The present investigation entitled “Effect of seed pre - treatment and foliar application of zinc on growth, physiological parameters and yield of mungbean (Vigna radiata L.) under water stress” was undertaken at Agricultural College Farm, Bapatla during rabi, 2017-18.The experiment was laid out in split plot design with two main treatments viz., no stress i.e. control (M0) and water stress from flowering stage (i.e. from 30 DAS) upto harvest (M1) and seven sub treatments viz., no zinc application (S0), seed treatment with 0.05 and 0.075% ZnSO4 solution for 5 hrs before sowing (S1 and S2, respectively), foliar spray of zinc @ 300, 400 and 500 ppm at 30 DAS (S3, S4 and S5, respectively) and water spray at 30 DAS (S6) in three replications. The results of the study revealed that, significant differences were observed between main and sub treatments and their interactions. Plant height and number of branches plant-1 decreased significantly under water stress condition, and the decrease was 5.0 and 14.7 per cent with the plants that were subjected to water stress from flowering stage, respectively, over control plants. Foliar spray of zinc @ 500 ppm at 30 DAS increased the plant height and number of branches by 21.6 and 20.9 per cent, respectively, compared to untreated plants. Under water stress condition, foliar spray of zinc @ 500 ppm at 30 DAS (M1S5) recorded 23.9 per cent increase in number of branches compared to no zinc application (M1S0). Leaf area was reduced by 14.8 per cent and leaf, stem, reproductive parts and total dry matter was decreased by 23.0, 23.3, 15.3 and 18.7 per cent, respectively in the plants that were subjected to stress from flowering stage over control plants. Foliar zinc spray @ 500 ppm at 30 DAS increased the leaf area by 30.0 per cent at 45 DAS and; leaf, stem, reproductive parts dry matter and total dry matter by 24.6, 24.8, 20.9 and 22.5 per cent, respectively, over untreated plants. Normal irrigated plants sprayed with zinc @ 500 ppm (M0S5) recorded the highest values of above parameters and the lowest values were recorded by the stressed plants with no zinc application (M1S0). Under water stress, mungbean plants sprayed with zinc @ 500 ppm at 30 DAS (M1S5) increased the leaf area and leaf, stem, reproductive parts and total dry matter by 23.9 and 17.6, 16.4, 23.9 and 21.3 per cent, respectively, over unsprayed plants (M1S0). The plants that were subjected to water stress from flowering stage decreased the RWC, total chlorophyll and carotenoid contents by 10.0, 7.5 and 12.6 per cent, respectively; and increased the proline accumulation and SOD activity by 10.3 and 30.0 per cent, respectively, over control plants. Zinc foliar spray @ 500 ppm at 30 DAS increased the RWC, total chlorophyll and carotenoid contents by 8.1, 10.2 and 6.1 per cent; and increased the proline and SOD activity by 10.8 and 21.3 per cent, respectively, over untreated plants. The plants that were stressed from flowering stage with foliar spray of zinc @ 500 ppm at 30 DAS (M1S5) recorded 24.3 and 60.5 per cent increase in proline and SOD activity, respectively, compared with the unstressed plants with water spray (M0S6). Number of pods plant-1, 100 - seed weight and seed yield decreased by 23.0, 6.0 and 33.6 per cent, respectively, under water stress condition compared to irrigated plants. Foliar spray of zinc @ 500 ppm at 30 DAS increased the number of pods plant-1, number of seeds pod-1, 100 - seed weight and seed yield by 24.7, 20.0, 3.3 and 55.2 per cent, respectively, over untreated plants. Foliar zinc spray @ 400 ppm at 30 DAS and seed pre - treatment with zinc @ 0.075% before sowing came in the second order pertaining to the improvement of all yield parameters. Irrigated plants that were sprayed with zinc @ 500 ppm at 30 DAS (M0S5) increased the number of pods plant-1 and seed yield by 31.0 and 65.0 per cent, respectively, over unsprayed plants (M0S0), whereas stressed plants from flowering stage sprayed with zinc @ 500 ppm at 30 DAS (M1S5) increased the number of pods plant-1 and seed yield by 17.0 and 42.0 per cent, respectively, over untreated plants (M1S0). According to the results obtained, it can be concluded that, foliar application of zinc @ 500 ppm at 30 DAS could improve the growth, yield and yield components of mungbean plants both under irrigated as well as water stress conditions. Zinc foliar spray @ 400 ppm at 30 DAS and seed pre - treatment with zinc @ 0.075% before sowing came in the second order. The use of zinc spray @ 500 ppm at 30 DAS especially under stress condition, could alleviate the negative effects of water stress on growth and yield of mungbean by increasing the antioxidant defence system in terms of higher activity of superoxide dismutase, carotenoid content and proline accumulation, which helped the stressed plants to grow successfully from flowering to maturity.
