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.

    SUSTAINING SOIL HEALTH IN RICE (Oryza sativa L.)THROUGH AQUATIC WEED COMPOSTS
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) BALACHENNAIAH, Y; Dr. P. MADHU VANI
    A green house experiment entitled “Sustaining soil health in rice (Oryza sativa L.) through aquatic weed composts” was conducted at Department of Soil Science and Agricultural Chemistry, Bapatla to study the effect of compost prepared from aquatic weeds on soil properties and performance of rice in terms of yield and nutrient uptake, besides the physical, physico-chemical, chemical and biological properties of soil. The experimental soil was clay in texture, neutral in reaction, medium in organic carbon (0.35%), low in available nitrogen (235 kg ha-1), medium in phosphorus (24.6 kg ha-1) and high in potassium (386 kg ha-1). All the micronutrients were above the critical limit except zinc. The experiment consists of ten treatments viz., Recommended dose of fertilizer nitrogen only (T1-160 kg ha-1) and integrated use of fertilizer nitrogen with Eichhornia, Ipomoea compost and FYM at three levels of substitution( 25, 50 and 75 % RDFN ). The treatments were laid out in completely randomized design and replicated six times. Aqautic weed compost and FYM were applied to soil as per the treatments based on their nitrogen content one week before transplanting of rice seedlings. Fertilizer nitrogen, phosphorus and potassium were applied through urea, single superphosphate and muriate of potash. 100 per cent recommended dose of nitrogen (160 kg ha-1) and 75, 50 and 25 per cent N in combination with organics was applied in three equal splits. Whereas, phosphorus and potassium @ 60 and 40 kg of P2O5 and K2O ha-1 were applied uniformly to all the pots. Entire quantity of phosphorus was applied at transplanting and potassium was applied in two equal splits. Standard methods of analysis were followed for estimating the nutrient composition of fresh weed biomass, compost prepared from those and FYM. Plant samples collected at 60 DAT and 120 DAT and soil samples collected at 15, 30, 60, 90 and 120 DAT were also analysed chemically for nutrient composition and various soil properties. The compost prepared from Ipomoea contained higher amounts of macro and micronutrients, narrower C:N and C:P ratio than Eichhornia compost and FYM. The physical and physico-chemical properties viz., bulk density, pH, EC and CEC were not significantly influenced by imposed treatments. The organic carbon, available macro and micronutrient contents and biological properties viz., dehydrogenese activity, biomass carbon and respiration rate in soil at 15, 30, 60, 90 and 120 DAT were significantly influenced by the treatments. Among the treatments, the treatment T9 which was substituted by 75 per cent nitrogen through Ipomoea compost was superior in improving the soil properties whereas, the treatment T1 was inferior which received 100 per cent RDFN. The performance of rice in terms of drymatter production, grain and straw yields, nutrient uptake at 60 and 120 DAT was significantly influenced by the treatments. The treatment (T3) which was integrated with 75 per cent RDFN and 25 per cent RDN through Ipomoea compost recorded maximum dry matter production, grain and straw yield and nutrient up take. Next best treatment was T2 which received same level of fertilizer nitrogen along with 25 per cent nitrogen through Eichhornia compost. Significant and positive correlations were observed between soil properties and performance of rice. Considering the soil health and rice productivity, the application of 75 per cent nitrogen through Eichhornia, Ipomoea composts and FYM along with 25 per cent nitrogen through fertilizer and 75 per cent RDFN+ 25 per cent RDN through Eichhornia, Ipomoea composts and FYM was found to be beneficial in improving the soil properties and yield of rice as compared to sole application of fertilizer nitrogen.
