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.

    PRODUCTIVITY OF MAIZE AS AFFECTED BY CROP RESIDUE INCORPORATION AND NITROGEN LEVELS IN LEGUME – CEREAL SEQUENCE
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) AMMAJI, PYDI; PULLA RAO, Ch
    A field experiment entitled “Productivity of maize as affected by crop residue incorporation and nitrogen levels in legume - cereal sequence” was conducted for two consecutive years (2011-12 and 2012-13) on sandy clay soil at Agricultural college, Aswaropet, Khammam (dt.), Andhra Pradesh with an objective to find out the influence of kharif legumes, residue management practices and nitrogen levels on the performance of maize crop. The experiment was laid out in split- split plot design and replicated thrice. The treatments consisted of three legumes, viz., cowpea, (M1) fieldbean (M2) and greengram (M3) as main plot treatments during the kharif season and two residue management practices viz., residue removal (I1) and residue incorporation (I2) as sub- plot treatments. Four nitrogen levels 75 kg ha-1 (N1), 150 kg ha-1(N2), 225 kg ha-1 (N3) and 300 kg ha-1 (N4) as sub- sub plot treatments allocated to maize during rabi season. Therefore, each kharif main treatment was divided into 8 sub- sub treatments during rabi season. The trial was repeated in a separate field in the second year. During two years of the study, Co-4, HA-3, MGG-295 varieties of cowpea, field bean and greengram respectively, were raised as kharif legumes while 30-V-92, a popular maize hybrid was grown during rabi. Among the different legumes evaluated,the highest gross returns, net returns and benefit cost ratio were recorded by greengram during both years of study. The highest pod yield, fresh and drymatter yields and greengram equivalent yields were obtained with cowpea followed by fieldbean and greengram crops. The total microbial population numerically increased over the initial value by taking legume crops in the sequence. Incorporation of crop residues has further increased the total microflora of the soil over the residue removal. Decreased trend of the total microbes was seen after the harvest of maize. The growth parameters of maize like plant height and drymatter accumulation were significantly influenced by legume crops, residue management practices and nitrogen levels. The highest plant height and drymatter accumulation of maize were recorded when grown as succeeding crop to cowpea followed by field bean during both the years. Incorporation of crop residues has resulted in significant improvement in growth parameters over their removal. Application of higher levels of nitrogen (300 kg ha-1) was found significantly superior to the lower levels during both the years but was comparable with 225 kg N ha-1. Similarly, yield attributes like number of cobs per plant, number of kernel rows per cob, number of kernels per cob, test weight were significantly higher when cowpea was taken as a preceding crop to maize. Residue incorporation has resulted in significant improvement in yield attributing characters compared to residue removal with all the three kharif legumes. Application of nitrogen @ 300 kg ha-1 was found to be significantly superior to 75 and 150 kg N ha-1 but comparable with 225 kg N ha-1. Higher kernel and stover yields were also obtained when cowpea was grown as a preceding crop to maize. Residue incorporation was found to be significantly superior in enhancing the kernel and stover yields of maize. Increase in the dose of nitrogen has increased in the grain and stover yields of maize. Application of N at 300 kg ha-1 was significantly superior to lower levels (75 and 150 kg ha-1) but remained at par with 225 kg N ha-1. Nutrient uptake of N, P and K at different intervals of maize crop growth had also followed the similar trend. The N, P and K uptake of kharif legume crops was more with cowpea followed by field bean and greengram during both the years of investigation. The nutrient uptake of maize was significantly high when it is preceded by cowpea followed by field bean and greengram. Residue incorporation had resulted in significantly highest N, P and K uptake than the residue removal. The uptake of N, P, and K was significantly higher with 300 kg N ha-1 applied plots over the lower doses. The soil available N, P, K after harvest of maize was the maximum in cowpea followed by field bean and greengram. From the investigation conducted for two consecutive years with different legumes, soil incorporation of residues and nitrogen levels, it can be concluded that the cowpea - maize sequence was profitable with incorporation of crop residues either in combination with 225 or 300 kg N ha-1 in Central Telangana Zone of Andhra Pradesh.
