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.

    DEVELOPMENT AND EVALUATION OF SEMI AUTOMATIC INTER AND INTRA ROW WEEDER FOR WIDER ROW SPACED CROPS
    (guntur, 2022-08-18) KISHORE, ARIGELA; JOSEPH REDDY, S.
    Weeds are unwanted and undesirable plants which interfere with the utilization of land and water resources and thus adversely affect crop growth. They can also be referred as plants out of place. Weeds compete with the beneficial and desired vegetation in crop lands, forests, aquatic systems etc. Weeding is an essential requirement to enhance crop growth. Handling the weeds nearby crop plants needs more attention and operation of machine is difficult along with crop. Hence, it is weeds grow mostly carried at present by engaging manual labor and become a labor intensive agricultural operation. Weeding accounts for about 25 % of the total labour requirement during a cultivation season. Whereas on the other hand machines can perform weed control when the crops are wellrooted, because if the intra-row weeders mentioned above have contact with the crops, the crops will not be damaged. This requirement causes a difficulty in controlling weeds at very early planting stage. The crop parameters those influence the weeding operation are row to row spacing, intra row spacing between the plants and also the crop physical parameters. Generally, the row to row spacing in wider spaced crops varies from 60 to 90 cm or 60 to 120 cm. while plant to plant spacing varies from 30 to 60 cm. The height of the plant, number of branches and crop canopy varies at different stages of weeding also influence the design of the weeding machine. Clearance required between the rows and also from ground to chassis of the power source, in case of power operated weeding equipment also effect the weeding efficiency. The height of the plant as well as the canopy of the plant at different stages are to be taken into consideration to improve weeding efficiency and to reduce the plant damage, particularly, while working between the plants with in the row. A study was therefore undertaken on “development and evaluation of semiautomatic inter and intra row weeder for wider row spaced crops” at Dr. NTR College of Agricultural Engineering, Bapatla. The tractor mounted implement was evaluated by varying forward speeds i.e., 0.6, 0.8 and 1.0 km h-1 at constant RPM of 180, 220 and 290 respectively and 2, 4 and 6 cm depth of operation levels in chilli crop. Name of the Author : ARIGELA KISHORE Title of the thesis : “Development and Evaluation of Semi- Automatic Inter and Intra Row Weeder for Wider Row Spaced Crops” Degree to which it is submitted : Master of Technology Faculty : Agricultural Engineering & Technology Major field of study : FARM MACHINERY AND POWER ENGINEERING Major Advisor : Dr. S. JOSEPH REDDY University : ACHARYA N. G. RANGA AGRICULTURAL UNIVERSITY Year of Submission : 2021 Lower weeding efficiencies were obtained at all depth of operation levels at forward speed of 0.6 km h-1. The rate of increase in weeding efficiency was more when forward speed increased than increase in depth of operation. The weeding efficiency was almost constant for further increase of forward speed from 1.0 to 1.8 km h-1. It was clear that the percentage of plant damage was zero or constant above 45 cm plant to plant distance. Below 45 cm plant to plant distance, the percentage of plant damage was found to be from 0 to 100 %. Draft increased with the increase in forward speed at all levels of depth of operation. It was observed that the field capacity increased with the increase of forward speed at all levels of depth of operation in all the crops both at 45 cm intra row spacing. It was observed that the fuel consumption was almost constant for further increase of forward speed from 1.0 to 1.8 km h-1. Cost of operation with developed inter and intra row weeder was observed to be low when compared with traditional method of weeding operation. The saving in cost was about Rs. 5,220 ha-1 over traditional method of weeding. keywords: Semi-automatic, inter and intra row, depth, weeding efficiency, plant damage, draft, field capacity.
