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.

    DYNAMICS OF SOIL CHARACTERISTICS AS INFLUENCED BY ORGANIC AND INORGANIC SOURCES OF NUTRIENTS IN RICE FALLOW MAIZE CROPPING SYSTEM
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) MOHANA RAO, PULI; Dr. P.R.K. PRASAD
    In order to arrive at a profitable and eco-friendly nutrient management, it is necessary to consider cropping sequence as a whole rather than an individual crop, as the need for different nutrients by a crop would vary depending upon the preceding crop and its nutrient management. With this background, a field experiment was conducted for two consecutive years (2011-2012 and 2012-2013) on fine texture soils of Agricultural college farm, Bapatla. The experiment was laidout in a randomized block design for rice in kharif season with four treatments and replicated five times. The treatments consisted of M1 (RDF - Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75%NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. The experiment on rice - maize sequence as detailed above was repeated on a separate site but in the same block during kharif 2012 and rabi 2013, respectively. Popular cultivars of rice and maize, BPT – 5204 and 30 V 92, respectively, were used for the study. Data collected on growth parameters viz., plant height, dry matter accumulation, yield attributes, grain yield, straw yield and nutrient content of rice were significantly higher with the application of 100%NPK in combination with FYM @10t ha-1. However, it was on par with that of green manuringtogether with 100% NPK during both the years of the study. Data collected on succeeding maize on growth parameters, yield attributes, yield, and nutrient content and uptake were significantly influenced by the nutrient management imposed to preceding rice crop, irrespective of NPK levels given to succeeding maize in the sequence. Plant height, dry matter accumulation, cob length, number of kernels cob-1 and kernel weight cob-1, test weight, kernel yield, stover yield, nutrient content and uptake of maize recorded in all those plots, which received organics along with 100% NPK to preceding rice were more than those received fertilizer NPK alone. Irrespective of nutrient management in kharif rice, increased N PK application to maize (75% to 175%) increased the kernel yield significantly in both the years (6825kg ha-1 to 8949kg ha-1 and 6544kg ha-1 to 8367kg ha-1, respectively). The maximum kernel yield (9116kg ha-1) of maize during 2012 was recorded with the application of 175% NPK and the residual effect of green manuring along with 100% NPK imposed to preceding rice crop whereas it was recorded with the application of 175% NPK and the residual effect of FYM @ 10t ha-1 along with 100% NPK imposed to preceding rice crop during 2013. The data regarding influence of organics applied to preceding rice crop and NPK levels applied to maize on nutrient content and uptake at different growth stages during both the years of the study was increased significantly with increase in level of NPK application to maize up to 125% NPK (N3) whereas, the treatments N3, N4 and N5 were on par with each other regardless the organics applied to preceding rice crop during both the years of the study. Application of organics in combination with inorganic fertilizers to preceding rice crop, irrespective of NPK levels, resulted in significant increase in nutrient content and uptake of succeeding maize in rabi than the treatment that had not received organics during both the years of study. In general, the available nutrient status and soil fertility status after harvest of each cropping sequence was higher by following organics along with 100% NPK imposed to preceding rice crop than that of 100% NPK alone.
