Acharya N. G. Ranga Agricultural University, Guntur (AP)

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 DEVELOPMENT AND PERFORMANCE EVALUATION OF PUNCH PLANTER FOR MAIZE IN RICE FALLOWS
    (Acharya N.G. Ranga Agricultural University, 2018) HARI BABU, B; JOSEPH REDDY, S
    Maize (Zea mays L.) is an important cereal food crop of the world with the highest production and productivity as compared to rice and wheat. It is the most versatile crop grown in more than 166 countries around the globe. During the year 2017-18, Andhra Pradesh ranked in 2nd in maize productivity in India.(Anonymous, 2018) Sowing is an important and time bound operation for crop cultivation. Early or delayed sowing adversely effects crop yield. The recommended seed rate has to be maintained by adopting adequate inter and intra row distance especially in maize crop. The crops grow uniformly if seeds are planted at uniform spacing. Thus, to obtain maximum yields, seeds should be planted at the desired spacing and in such a way all viable seeds germinate and emerge promptly To offer better seeding performance than conventional planters under no-till conditions a punch planter was developed which moves a minimum amount of soil and residue and offers precision in seed spacing. Minimal research has been carried to overcome limitations in punch planting concept, specifically making punches and simultaneously seed placement to obtain optimum population rate. The developed method of punch planting involves placing seeds into holes instead of furrows, which creates favorable environment for seed by providing good contact between seed and soil. The increase in use of mini tractors in all the states necessitated to design the technology for precision planting of maize to benefit the farming community. A mini tractor operated punch planter was designed and developed at College of Agricultural Engineering, Bapatla. It consisted of two major units with different components. The first unit was punching unit and second one seed placing unit. Punching unit draws power from tractor PTO and the main function is to punch holes in the field at a desired spacing and depth. The seed dropping unit is operated by punching rod and the main function is to drop single seed in the punches. The overall speed reduction ratios from engine to punch wheel were 22.61 and 15.53 for PTO lever position 1 and 2, respectively. In PTO lever position 1 and gear position 1, the forward speed of the tractor increased from 0.35 to 0.98 kmh-1 by increasing engine speed from 800 to 2400 rpm. In gear position 2 and 3, it was 0.80 to 1.53 kmh-1 and 1.69 to 3.28 kmh-1 , respectively. In PTO lever position 2 and gear position 1, the forward speed of the tractor increased from 0.35 to 0.99 kmh-1 by increasing the engine speed from 800 to 2400 rpm. In gear position 2 and 3 it was 0.85 to 1.68 kmh-1 and 1.75 to 3.50 kmh-1 , respectively. No effect of PTO lever position on forward speed of the tractor was observed. The mean punch spacings of 10, 16, 24, 35 and 53 cm were obtained in different gear and PTO lever positions. No significant effect on punch spacing in a particular gear and PTO lever position with forward speed of the tractor was observed. The punch spacings obtained in PTO lever position 1 and varying gear positions 1, 2 and 3 were 16, 24 and 53 cm, respectively. The punch spacings were obtained in PTO lever position 2 and varying gear positions 1,2 and 3 were 10, 16 and 35 cm, respectively. The required punch spacings can be obtained by selecting the gear and PTO lever position and the forward speed of the tractor can be maintained between 0.35 to 3.28 kmh-1. The seed miss index increased with the increase of punch planter speed in both punch spacings and also for two types of punch shapes. It was observed that in sandy clay loam soil, seed miss index was increased from 9.6 to 13.9% and 7.5 to 10.8% for 24 cm punch spacing and for type1 and type 2 punches, respectively, as the speed increased 0.8 to 1.7 kmh-1. In case of 16 cm punch spacing, it was observed that seed miss index was increased from 9.3 to 13.3% and 9.0 to 13.0% for type1 and type 2 punches, respectively, as the speed increased 0.8 to 1.7 kmh-1. The statistical analysis showed that there was a significant effect of interaction forward speed & type of punch and forward speed & punch spacing on index in both sandy clay loam and clay soil with rice fallow. decreased with the increase of punch planter speed in both punch spacings and also for two types of punches. I from 84.9 to 83.4% and 85.8 to 84.9% for 24 cm punch spacing and for type1 and type 2 punches, respectively, as spacing, it was observed that quality of feed index was decreased fro and 84.3 to 83.7% for type1 and type 2 punches respectively The theoretical field capacity was 0.1, 0.16 and 0.20 hah h-1 forward speed of operation efficiency were observed forward speeds of 0.8, 1.3 and 1.7 kmh obtained as 1.20, 1.48 and 2.14 Lh respectively. The total fixed cost with mini tractor and punch planter w 233.0/-, 18.0/- per hour with mini tractor was found to be and 66.0% in terms of manpower, time of operation and cost of operation due to use of punch planter than traditional manual sowing.
