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.

    AGRONOMIC EVALUATION OF CROP ESTABLISHMENT TECHNIQUES, N-LEVELS ON RICE (Oryza sativa L.) AND EFFECTS ON SUCCEEDING GREENGRAM (Vigna radiata)
    (Acharya N.G. Ranga Agricultural University, 2018) AMARA JYOTHI, P; MARTIN LUTHER, L
    A field experiment entitled “Agronomic evaluation of crop establishment techniques, N-levels on rice (Oryza sativa L.) and effects on succeeding greengram (Vigna radiata)” was conducted for two consecutive years (2015-16 and 2016-17) on sandy clay loam soils of Agricultural Research Station, Ragolu. The experiment was laid out in a split plot design, replicated thrice with four crop establishment techniques as main plots and five nitrogen levels as sub plots. The main plot treatments consisted of (i) Dry direct sown (DDS) rice, (ii) Aerobic rice (iii) Planting with machine and (iv) Normal planting. The subplot treatments consisted of five nitrogen levels (90, 120, 150, 180 and 210 kg N ha-1). Before harvesting of rice, greengram was sown to assess the residual effects of treatments given to rice in rice - greenram sequence. Cultivars used in the study for rice and greengram were MTU 1001 and LGG 460 respectively. Among crop establishment techniques, planting with machine recorded significantly higher plant height, drymatter production, yield attributes, grain yield, straw yield, nutrient uptake, nitrogen use efficiency and gross returns compared to other crop establishment techniques of rice. However, DDS rice recorded higher net returns and return per rupee investment and aerobic rice registered maximum water productivity. Application of nitrogen @ 150 kg N ha-1 recorded significantly higher growth and yield attributes, grain and straw yield, NPK uptake and available nitrogen, phosphorus and potassium in the soil after harvest of rice over that of other nitrogen levels. Whereas the N use efficiency was found to be superior with nitrogen application @ 120 kg N ha-1 compared to other levels. Though the maximum gross returns, net returns and return per rupee investment were noticed with 210 kg N ha-1, which was however comparable with 180 and 150 kg N ha-1. Number of pods plant-1, number of seed pod-1, seed yield, haulm yield, gross returns, net returns, benefit cost ratio of green gram and the available nitrogen status in soil after harvest of greengram were significantly higher with aerobic rice establishment technique over planting with machine and comparable with DDS rice. There was a progressive increase in seed yield of succeeding greengram with the increase in nitrogen levels applied to the preceeding rice crop in the sequence. Among N levels the highest seed yield of greengram was recorded with 210 kg N ha-1. However the difference in seed yield among the N levels was measurable up to application of N @ 150 kg N ha-1 only. Maximum system productivity of rice–greengram was recorded with planting with machine technique followed by normal planting. System productivity of rice–greengram increased progressively with increase in level of nitrogen. Highest net returns of system was recorded with DDS rice-greengram followed by planting with machine -greengram system. The results of the study “Agronomic evaluation of crop establishment techniques, N- levels on rice and effects on succeeding greengram” conducted consecutively for two years indicated that, among rice establishment techniques planting with machine emerged as productive and dry direct sown rice was emerged as profitable and aerobic rice emerged as water saving techniques of rice. Irrespective of the crop establishment techniques, application of nitrogen @ 150 kg N ha-1 was found to be optimum for reaping higher grain yield and economic returns.
