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.

    EVALUATION OF YIELD AND QUALITY OF GROUNDNUT UNDER HIGH DENSITY PLANTATIONS WITH GRADED LEVELS OF PHOSPHORUS
    (Acharya N.G. Ranga Agricultural University, Guntur, 2021-11-18) . SUNIL KUMAR, T; Dr. SUMATHI, V.
    A field experiment entitled “Evaluation of yield and quality of groundnut under high density plantations with graded levels of phosphorus” was carried out during rabi, 2019-20 on sandy loam soils of dryland farm of S.V. Agricultural College, Tirupati campus of Acharya N.G. Ranga Agricultural University. The experiment was laid out in randomized block design with factorial concept, with three replications. The treatments comprised of three plant densities viz., 22.5 cm x 10 cm (4,44,444 plants ha-1, D1), 20 cm x 7.5 cm (6,66,666 plants ha-1, D2) and 22.5 cm x 5.0 cm (8,88,888 plants ha-1, D3) and four phosphorus levels viz., 25.0 kg P2O5 ha-1 (P1), 37.5 kg P2O5 ha-1 (P2), 50.0 kg P2O5 ha-1 (P3) and 62.5 kg P2O5 ha-1 (P4). Groundnut cultivar ‘Dharani’ was tested in the present experiment. Phosphorus was applied as per the treatments, while nitrogen and potassium was applied common to all the treatments and gypsum was applied just before flowering @ 500 kg ha-1. Plant densities and phosphorus levels significantly influenced the growth parameters, yield attributes, yield, nutrient uptake, and economic returns of groundnut as well as post-harvest soil available nutrients. Plant height was higher at plant density of 6.66 lakh ha-1 and it was comparable with plant height at plant density of 8.88 lakh ha-1. Application of 62.5 kg P2O5 ha-1 produced taller plants. At all stages of sampling, leaf area plant-1 was maximum at 4.44 lakh ha-1 density, whereas, dry matter production increased with increase in plant density from 4.44 to 8.88 lakh ha-1. Leaf area plant-1 was maximum with application of 50 kg P2O5 ha-1 and DMP was higher at 62.5 kg P2O5 ha-1. Higher number of nodules was produced at plant density 6.66 lakh ha-1, but on par with 4.44 lakh ha-1 density except at harvest, where nodule count decreased with increase in plant density. Higher nodule count was obtained with application of 62.5 kg P2O5 ha-1. xvi Regarding the yield attributes viz., number of pods plant-1, number of kernels pod1, 100-pod weight, and 100-kernel weight were higher in lower plant density of 4.44 lakh ha-1. Application of 62.5 kg P2O5 ha-1 recorded higher yield attributes which was on par with 50 kg P2O5 ha-1. Pod yield, kernel yield and shelling percentage were higher with lower plant density of 4.44 lakh ha-1. Whereas, haulm yield was higher in higher plant density of 8.88 lakh ha-1. Regarding phosphorus levels, application of 50 kg P2O5 ha-1 recorded higher pod yield, kernel yield and shelling percentage and it was on par with that of 62.5 kg P2O5 ha-1. Interaction between plant densities and phosphorus levels was found to be significant only in influencing pod yield. Higher pod yield was recorded in combination of 4.44 lakh ha-1 with 50 kg P2O5 ha-1 followed by 6.66 lakh ha-1 with 62.5 kg P2O5 ha-1. Plant densities and phosphorus levels failed to exert significant influence on quality parameters viz., oil and protein content of groundnut. Nitrogen and potassium uptake by groundnut crop was higher in plots sown with higher plant density of 8.88 lakh ha-1 and fertilized with 62.5 kg P2O5 ha-1. Phosphorus uptake exerted significant disparity among treatments, significant interaction was found at 25 DAS. Phosphorus uptake increased with increase in plant density and phosphorus fertilization. The higher post-harvest soil nutrient status was registered with plots of lower plant density of 4.44 lakh ha-1 and plots supplied with higher levels of phosphorus i.e. 62.5 kg P2O5 ha-1. Among varied treatments imposed, the higher gross returns, net returns and benefit-cost ratio was realized when groundnut was grown at plant density of 4.44 lakh ha-1 conjugated with 50 kg P2O5 ha-1, which was comparable with 6.66 lakh ha-1 plant density with 62.5 kg P2O5 ha-1. The lower economic returns was obtained with 8.88 lakh ha-1 with 25 kg P2O5 ha-1. In conclusion, the present study disclosed that growing of rabi groundnut on sandy loam soils at a plant density of 4.44 lakh ha-1 with 50 kg P2O5 ha-1 resulted in higher pod yield and economic returns. However, when farmers are opting for high density planting, maintenance of groundnut population at 6.66 lakh ha-1 in conjugation with 62.5 kg P2O5 ha-1 will be recommended for enhancing productivity and monetary returns.
