Acharya N. G. Ranga Agricultural University, Guntur (AP)

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 ZINC APPLICATION ON GROWTH, RE-MOBILISATION EFFICIENCY AND GRAIN FORTIFICATION IN FINGER MILLET (Eleusine coracana (L.) Gaertn)
    (guntur, 2022-08-08) MRUDULA, G.; SANDHYA RANI, P.
    The present investigation entitled “Effect of zinc application on growth, re-mobilisation efficiency and grain fortification in finger millet (Eleusine coracana (L.) Gaertn)” was conducted in two consecutive years during kharif, 2019 and 2020 at S.V. Agricultural College, Tirupati, Andhra Pradesh. The experiment was laid out in split plot design with three replication and two varieties Vakula (V1) and Tirumala (V2) as main treatments; seven zinc treatments viz., Control (T1), 60-30-20 of NPK + FYM @ 10t ha-1 (T2), T2 + soil application of ZnSO4 @ 25 kg ha-1 as basal (T3), T2 + soil application of chelated zinc sulphate @ 5 kg ha-1 as basal (T4), T2 + foliar spray of 0.2% ZnSO4 at ear head emergence stage (T5), T2 + foliar spray of 0.2% ZnSO4 at grain filling stage (T6), T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) as sub treatments. Crop response to different treatments was measured in terms of quantitative and qualitative indices viz., morphological, physiological, yield and its attributes, quality parameters of grain, zinc partitioning among plant parts and re-mobilization of zinc to grains. Between the varieties, Tirumala (V2) variety recorded higher quantitative and qualitative indices compared to Vakula (V1) variety. Among the sub-treatments, upto ear head emergence stage, T2 + soil application of ZnSO4 @ 25 kg ha-1 as basal (T3) recorded significantly higher growth parameters, followed by T2 + soil application of chelated zinc @ 5 kg ha-1 as basal (T4). After ear head emergence stage, T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) recorded significantly highest growth, yield and quality parameters of finger xv millet. The interaction effects revealed that the dry matter production and growth parameters which represent sink activity viz., crop growth rate (CGR), net assimilation rate (NAR) and sink capacity viz., leaf area index (LAI), leaf area duration (LAD), specific leaf area (SLA), specific leaf weight (SLW) and SCMR were higher in V2T7 i.e., Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7), followed by V1T7 i.e., Vakula (V1) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) during kharif, 2019 and 2020. The growth parameters viz., plant height, number of tillers per plant, leaf area, total dry matter revealed that, V2T3 i.e., Tirumala (V2) variety with T2 + soil application of ZnSO4 @ 25 kg ha-1 as basal (T3) recorded significantly highest growth upto ear head emergence stage. And thereafter V2T7 i.e., Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) recorded significantly higher growth parameters compared to other interactions. The yield attributes viz., number of productive tillers per plant, number of fingers per plant, 1000 grain weight were significantly highest in V2T7 i.e. Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7), followed by V1T7 i.e., Vakula (V1) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) compared to all other interaction effects. Highest grain yield, straw yield and harvest index were recorded in V2T7 treatment compared to all other interactions during both years of experiment. Among the interaction effects of grain quality parameters, V2T7 i.e., Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) recorded significantly higher protein, iron, zinc and calcium content, followed by V1T7 i.e., Vakula (V1) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) compared to other interactions. The contribution of zinc from different plant parts viz., root, stem, leaf and leaf sheath to grain was highest in V2T7 i.e. Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) and the least contribution was noticed by V1T1 i.e. Vakula (V1) variety with control i.e. no fertilizer and also no zinc (T1) during kharif, 2019 and 2020. Re-mobilization efficiency was higher in V2T7 i.e. Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7), followed by V1T7 i.e. Vakula (V1) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7) and least was recorded by V1T1 i.e. Vakula (V1) variety with control (T1). xvi The zinc use efficiency and root to shoot translocation index were lesser in V2T7 i.e. Tirumala (V2) variety with T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7). Whereas V1T1 i.e. Vakula (V1) variety with control (T1) recorded higher translocation compared to other interactions. The highest post harvest available soil zinc status was recorded with T3 i.e. T2 + soil application of ZnSO4 @ 25 kg ha-1 as basal and T4 i.e. T2 + soil application of chelated zinc sulphate @ 5 kg ha-1 as basal with no significant difference between them. However, the available soil zinc status was low with control (T1). Based on the results obtained from the present study, it is evident that the variety Tirumala (V2) found effective for physiological efficiency, yield attributes, partitioning efficiency, quality, zinc fortification and grain quantity parameters compared to Vakula (V1). The soil application of T2 + ZnSO4 @ 25 kg ha-1 (T3) recorded increased growth parameters up to ear head emergence stage, However, T2 + foliar spray of 0.2% ZnSO4 at ear head emergence and grain filling stage (T7) proved to be the best with higher grain yield, partitioning of zinc to grain, re-mobilization efficiency and grain fortification.
