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.

    DESIGN AND DEVELOPMENT OF GROUNDNUT PLANTER - CUM- SITE SPECIFIC PRECISION WATER APPLICATOR
    (Acharya N.G. Ranga Agricultural University, 2018) ANITHA, GUGULOTH; ASHOK KUMAR, A
    Groundnut (Arachis hypogaea L.) is the sixth most important oilseed crop in the world. It contains 48-50% oil and 26-28% protein and is a rich source of dietary fiber, minerals and vitamins. Planting operation is one of the most important cultural practices associated with crop production. Increase in crop yield, cropping reliability, cropping frequency and crop returns all depend on the uniform and timely establishment of optimum plant population. In India, most of the farmers are small and marginal farmers; hence, there is a demand of small implements which could be used as multifunctional devices by attaching simple components to be fitted to the low hp tractor. In general, the groundnut crop has been planted during starting of the rainy season and most of the crop is cultivated under rain fed conditions. The basic idea of ground nut planter cum site specific precision water applicator is application of water/chemical at the targeted location i.e. seed placement and it can be done using modern sensors. With this system, seed planting and water/chemical application can be done simultaneously in a single operation. This increases the moisture content of soil and sustainability of seed for germination during nonrainy days. An attempt was made to develop a groundnut planter suitable for mini tractor. Before designing of groundnut planter suitable for the mini-tractor, all the required components were designed individually, made auto-cad drawings and fabricated the total machine using created drawings. An Electronic Control Unit (ECU) was developed for delivering the precision water at required time, by detecting the seed in seed delivery tube using IR obstacle sensor and activation of solenoid valve for delivering site specific precision water. The developed ground nut planter and electronic control unit for site specific precision water application unit were integrated to work as a single unit for planting as well as site specific water/chemical applications simultaneously. Initially ECU was tested under laboratory and it was observed that, the three IR sensors were responded well while focusing the seed in seed delivery tube. During field evaluation, it was observed that the draft force requirement of the planter found to vary from 125 to 296 kg as changing the depth of operation from 5.3 to 11.5 cm at varying speed of operation. The maximum seed mixing index of the planter was found as 9%. The uniformity of seed spacing in all the rows found to vary from 9.6 to 11.5 cm. The theoretical and actual field capacity of the planter found to vary from 0.06 to 0.15 ha/h and 0.05 to 0.11 ha/h as change in speed of operation from 1 to 2.5 km/h. The percentage wheel slip of the groundnut planter found to vary from 10.52 to 23.68% at varying depths of operation. The seed damage and water saving percentage of the planter cum developed ECU is 5% and 77% respectively. With this sensor based technology application of excess liquid chemical consumption could be saved which leads to reduction in environmental pollution Keywords: IR obstacle sensor, Solenoid valve, Microcontroller, Water saving; Planter.
