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.

    NITROGEN DYNAMICS AND NITROGEN USE EFFICIENCY WITH NEEM COATED UREA IN RICE CULTIVATION
    (Acharya N.G. Ranga Agricultural University, 2017) DEEPIKA, JANGAM; SUDHA RANI, Y
    A field experiment entitled “Nitrogen dynamics and nitrogen use efficiency with neem coated urea in rice cultivation” was conducted at Agricultural College Farm, Bapatla during kharif, 2016. The experimental soil was clay in texture, slightly alkaline in reaction and non-saline. The soil was medium in organic carbon and available nitrogen, high in available phosphorus and potassium and sufficient in sulphur. The soil was high in zinc, copper, manganese and iron. The experiment was laid out in RBD with nine treatments replicated thrice. The treatments comprised of T1- Control, T2-100% RDN through urea in 3 split doses, T3 - 75% RDN through neem coated urea in 3 split doses, T4 - 100% RDN through neem coated urea in 3 split doses, T5-125% RDN through neem coated urea in 3 split doses, T6-100% RDN through urea in 2 split doses, T7-75% RDN through neem coated urea in 2 split doses, T8-100% RDN through neem coated urea in 2 split doses, T9-125% RDN through neem coated urea in 2 split doses. Well decomposed farmyard manure @ 10 t ha-1 was applied to the field as per recommended dose ten days before transplanting. The inorganic nitrogen through urea and neem coated urea was applied in 3 splits (as basal and at tillering and panicle initiation stages) to four treatments i.e T2 to T5 and applied in 2 splits (as basal and in between tillering and panicle initiation stages) to four treatments i.e T6 to T9. Entire quantity of P2O5 in the form of SSP and K2O in the form of MOP were applied to all the treatments as basal dose at the time of transplanting. (Recommended dose of fertilizers was 120-60-40 kg NPK kg ha-1 ). The influence of various treatments on growth parameters, yield attributes, yield, soil properties (physical, physico-chemical properties and available nutrients), nutrient contents and uptake at different stages and forms of nitrogen at every three days and one week after application of fertilizers were determined by standard procedures. All growth parameters, productive tillers m-2 , filled grains per panicle, grain and straw yield were markedly influenced by the application of neem coated urea. Maximum grain yield was recorded with 125%RDN through neem coated urea in three split, which is on par with 100%RDN and 75%RDN through neem coated urea. The maximum nitrogen use efficiency and apparent N recovery was recorded in treatment 75% RDN through neem coated urea in 3 splits, while grain yield is on par with 125% RDN through neem coated urea. The soil properties viz., bulk density, pH, EC and organic carbon and micronutrients were not markedly influenced by the imposed treatments. There was a significant influence of the treatments on available nitrogen and phosphorus, but not on potassium. The available nitrogen and phosphorus contents were markedly influenced by the application of neem coated urea at all the crop growth stages. The nitrogen content of rice plants at all growth stages was markedly influenced by the treatments with highest N recorded in treatment supplied with 125% RDN through neem coated urea in three spits. The effect of treatments on other nutrients in plants was non-significant. The uptake of N, P, K, S and micro nutrients at all growth stages was markedly influenced by the treatments with higher values recorded with 125% recommended dose of neem coated urea in three spits which was at par with 100% RDN through urea applied in three and two splits. Application of neem coated urea showed significant influence on forms of nitrogen. Neem coated urea proved to be more efficient in maintaining the maximum amount of ammoniacal – N, total nitrogen and mineralizable – N and lower amount of nitrate – N than urea and control where no nitrogen was applied.
