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.

    CROP STAND ESTABLISHMENT AND NUTRIENT MANAGEMENT IN RICE BASED CROPPING SYSTEM IN NORTH COASTAL ANDHRA PRADESH
    (Acharya N.G. Ranga Agricultural University, Guntur, 2021-12-07) .RAJENDRA KUMAR, B; PRASAD, Dr. P.V.N.
    A field experiment entitled “Crop Stand Establishment and Nutrient Management in Rice based Cropping system in North Coastal Andhra Pradesh” was conducted for two consecutive years (2017 -18 and 2018-19) at the Agricultural College Farm, Naira. The experimental site was uniform in topography and the soil was a sandy loam in texture. The soil pH was slightly acidic, low in organic carbon, low in available nitrogen, medium in available phosphorus and medium in available potassium. The experimentation was conducted during both kharif and rabi seasons and during kharif experiment was laid out in split plot design with three replications. The treatments consisted of two main plots (Wet seeded rice (Drum seeding) and transplanting method) and four sub plots Viz., S1: 100% RDF (Chemical fertilizers); S2: 75% RDF+ 25% RDF through FYM; S3: 75% RDF + 25% RDF through green manure crop (Sunhemp); S4: 50% RDF + 25% RDF through FYM + 25% RDF through green manure crop (Sunhemp). During rabi rice fallow crops viz., blackgram, ragi and sunhemp were sown each where in kharif sub plot treatment which was sub divided into three sub-sub treatments and thus, double split plot design was adopted for rabi and the total number of plots during kharif was 24 (8×3=24) and during rabi was 72 (24×3=72) respectively. The experiment on rice-rice fallow crops sequence was repeated in another site during the 2nd year. Application of 75% RDF + 25% RDF through green manure crop (S3) manifested significantly superior performance in terms of growth characters of rice and other parameters studied, but remained on a par with the application of 100% RDF (S1) during both the years of study. The highest number of xxiii productive tillers m-2 (425 and 404), maximum number of filled grains panicle-1 (138 and 132) and test weight (24.22 and 22.53 g/1000 grains) were recorded respectively during first and second year of study with S3 treatment applied with 75% RDF + 25% RDF through green manure crop but it was on par with S1 treatment receiving 100% RDF. The lowest number of yield attributes were recorded with S4 50% RDF + 25% RDF through FYM + 25% RDF through green manure crop in both the years of study. Significantly higher grain (6166 and 5586 kg ha-1 ) and straw yield (7157 and 7143 kg ha-1 ) were recorded with the application of organic sources with 25% in S3 treatment and 75 % RDF + 25% RDF through green manure crop which was at par with S1 where only (100% RDF) chemical source of fertilizers were used. The lowest grain and straw yields were recorded when nutrient applied with 50% RDF + 25% RDF through FYM + 25% RDF through green manure crop during both the years of study. All the nutrient contents (%) and uptake (kg ha-1 ) i.e., nitrogen, phosphorus, and potassium at different growth stages including grain and straw have recorded the highest values with the treatment that received 75% RDF + 25% RDF through green manure which remained on par that was applied 100% RDF in both the years of study. Post harvest available soil N, P and K status was significantly influenced by nutrient management interventions. The N, P and K status in the soil was recorded higher with 50% RDF + 25% RDF through FYM + 25% RDF through green manure crop (S4) which was at par with 75% RDF + 25% RDF through FYM (S2) and was found significantly superior to the rest of the treatments. During rabi significant increase in growth and yield attributes of rice fallow crops (blackgram, ragi and sunhemp) was recorded with the treatment, which received 50% RDF + 25% RDF through FYM + 25% RDF through green manure crop (S4) which was however at par with 75% RDF+ 25% RDF through FYM (S2) during both the years of study. The residual effect of INM treatments iimposed in kharif rice on succeeding rice fallow crops, resulted in higher net return and return rupee-1 investment with 50% RDF along with 25% RDF through FYM + 25% RDF through green manure crop which was at par with 75% RDF + 25% RDF through FYM during both the years of study. Among the three rice fallow crops sunhemp recorded significantly higher net return rupee -1 investment (Rs. 63225 3.62) with 50% organic sources (FYM and green manure) and (Rs. 59097 3.38) with 25% organic sources (FYM) respectively. The second best crop in terms of net return and return rupee -1 investment was blackgram with Rs. 24401 and Rs. 23251 with return rupee -1 investment of 2.08 and 1.99, respectively. However, the crop ragi recorded the lowest net return and return rupee -1 investment.
