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.

    INTEGRATED WEED MANAGEMENT IN PEARLMILLET [Pennisetum glaucum (L.) R. Br. Emend. Stuntz]
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) SURYA PRAKASH, MISHRA; REDDI RAMU, Y
    A field experiment was conducted at S. V. Agricultural College Farm, Tirupati campus of Acharya N.G. Ranga Agricultural University of Andhra Pradesh, during kharif, 2014, to study the effect of integrated weed management practices on growth and yield of pearlmillet. The present investigation was laidout in a randomized block design with three replications. The experiment consisted of ten weed management practices viz., preemergence application of atrazine @ 750 g a.i. ha-1 (T1), pre-emergence application of oxyflourfen 100 g a.i. ha-1 (T2), pre-emergence application of atrazine @ 750 g a.i. ha-1 fb hand weeding at 30 DAS (T3), pre-emergence application of oxyflourfen @ 100 g a.i. ha-1 fb hand weeding at 30 DAS (T4), pre-emergence application of atrazine fb post-emergence application of chlorimuron-ethyl 10% + metsulfuronmethyl 10% @ 8 g a.i. ha-1 (T5), pre-emergence application of atrazine fb postemergence application of ethoxysulfuron @ 37.5 g a.i. ha-1 (T6), pre-emergence application of oxyflourfen fb post-emergence application of chlorimuron-ethyl 10% + metsulfuron-methyl 10% @ 8 g a.i. ha-1 (T7), pre-emergence application of oxyflourfen fb post-emergence application of ethoxysulfuron @ 8 g a.i. ha-1 (T8), hand weeding twice at 20 and 40 DAS (T9) and weedy check (T10). The test hybrid used in the present study was PHB –306. Weed flora observed in the experimental field accounted for three species of grasses, two species of sedges and ten species of broad leaved weeds. The lowest weed density and dry weight of weeds with the highest weed control efficiency was observed with hand weeding twice at 20 and 40 DAS (T9), which was however on par with pre-emergence application of atrazine @ 750 g a.i. ha-1 fb one hand weeding at 30 DAS (T3). Pre-emergence application of atrazine @ 750 g a.i. ha-1 fb xvi post-emergence application of ethoxysulfuron @ 37.5 g a.i. ha-1 (T6) or chlorimuron-ethyl 10% + metsulfuron-methyl 10% @ 8 g a.i. ha-1 (T5) and preemergence application of atrazine @ 750 g a.i. ha-1 alone (T1) were the next best treatments for the above said weed parameters, which maintained statistical similarity with each other. Pre-emergence application of oxyflourfen @ 100 g a.i. ha-1 alone (T2) or pre-emergence application of oxyflourfen @ 100 g a.i. ha-1 fb hand weeding at 30 DAS (T4) or post-emergence application of herbicides were inferior over that of atrazine. The highest weed density and dry weight of weeds along with the lowest weed control efficiency was associated with unweeded check (T10). The lowest nutrient uptake by weeds was observed with hand weeding twice at 20 and 40 DAS (T9), which was comparable with pre-emergence application of atrazine fb one hand weeding at 30 DAS (T3). The nutrient drain in the unweeded check (T10) recorded the highest nutrient uptake by weeds i.e., 23.4, 4.3 and 23.1 kg N, P and K ha-1, respectively. Among the weed management practices studied, hand weeding twice at 20 and 40 DAS (T9) resulted in the highest values of growth parameters viz., plant height, LAI, total number of tillers plant-1 and dry matter production and the highest values of yield attributes viz., number of panicles plant-1, panicle length, panicle girth, panicle weight, number of grains panicle-1 and test weight. These parameters were on par with pre-emergence application of atrazine fb one hand weeding at 30 DAS (T3). Pre-emergence application of oxyflourfen (T2, T4, T7 and T8) showed phytotoxicity scoring of ‘4.0’ on pearlmillet. The highest grain and straw yield was recorded with hand weeding twice at 20 and 40 DAS (T9), which was however comparable with pre-emergence application of atrazine fb one hand weeding at 30 DAS (T3). These treatments recorded 86.5 and 83.8 per cent higher yield, respectively compared to unweeded check (T10). The highest nutrient uptake by crop and the lowest nutrient uptake by weeds were noticed with hand weeding twice at 20 and 40 DAS (T9), which was comparable with pre-emergence application of atrazine fb one hand weeding at 30 DAS (T3). Among the weed management practices tried, the highest gross returns were observed with hand weeding twice at 20 and 40 DAS (T9), which was on par with pre-emergence application of atrazine fb one hand weeding at 30 DAS (T3). However, the later weed management practice recorded significantly higher net returns and benefit-cost ratio. In conclusion, the present study has revealed that hand weeding twice at 20 and 40 DAS resulted in effective control of all the categories of weeds and resulted in higher grain yield and gross returns. Pre-emergence application of atrazine @ 750 g a.i. ha-1 supplemented with hand weeding at 30 DAS recorded the highest net returns and benefit-cost ratio in pearlmillet.
