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.

    EFFECT OF PLANT DENSITY AND NITROGEN MANAGEMENT ON YIELD AND QUALITY OF SWEET CORN
    (ACHARYA N G RANGA AGRICULTURAL UNIVERSITY,GUNTUR, 2019) ANJANEYULU NAIK, A; SRINIVASA REDDY, M
    A field experiment entitled “Effect of plant density and nitrogen management on yield and quality of sweet corn (Zea mays var Saccharata)” was conducted at Agricultural College Farm, Mahanandi during kharif, 2018-2019. The experiment was carried out in randomized block design with factorial concept and the each treatment was replicated thrice. The treatments consisted of combination of three plant densities (D1 : 60 cm X 15 cm, D2 : 60 cm X 20 cm, and D3 : 60 cm X 25 cm) and five nitrogen management levels (T1: control, T2: 100% RDN, T3: 75 % RDN + FYM @ 10 t ha-1 , T4: 100% RDN + FYM @ 10 t ha-1 and T5 : 125% RDN + FYM @ 10 t ha-1) in Factor – I and Factor – II respectively. A popular sweet corn hybrid in this region, sugar-75, released by a private company M/s Syngenta India Limited, Baner, Pune, Maharashtra, was used for the study. The soil was sandy loam and it was slightly alkaline in reaction with a pH of 8.08; EC of 0.25 dSm-1, low in organic carbon (0.49%) and available nitrogen (166 kg ha-1), medium in available phosphorus (46.6 kg ha-1) and high in potassium (675.3 kg ha-1). Plant height, leaf area index and drymatter accumulation was maximum with a plant density of 60 cm X 15 cm which was significantly superior to 60 cm X 20 cm, and 60 cm X 25 cm. While, the planting density with 60 cm X 25 cm registered significantly the lowest plant height, leaf area index and drymatter accumulation. Application of 125% RDN + FYM @ 10 t ha-1 (T5) recorded significantly more plant height, leaf area index and drymatter accumulation compared to control, 100% RDN, 75 % RDN + FYM @ 10 t ha-1 throughout the growth period and was on par with 100% RDN + FYM @ 10 t ha-1. Higher number of days to 50 % tasseling and silking was recorded in a plant density of 60 cm X 20 cm and the lowest number of days was observed in 60 cm X 25 cm. The number of days taken to 50 percent tasseling, silking were significantly lowered when the crop was fertilized with 125% RDN + FYM @ 10 t ha-1 followed by 100 % RDN + FYM @ 10 t ha-1. Among the plant densities 60 cm X 25 cm recorded more yield attributing characters like no. of cob plant-1, cob length, 100 grain weight (g) and no. of grains per cob over the other treatments. Yield attributing character like no. of cob plant-1, cob length and 100 grain weight (g) were superior with the application of 125% RDN + FYM @ 10 t ha-1, however it was on a par with 100 % RDN + FYM @ 10 t ha-1 and no. of grains per cob were significantly superior in 100 % RDN + FYM @ 10 t ha-1 followed by 75 % RDN + FYM @ 10 t ha-1. Among the plant densities 60 cm X 25 cm recorded significantly higher cob yield and lower cob yield in 60 cm X 20 cm and higher stover yield in 60 cm X 15 cm and lower stover yield in 60 cm X 20 cm. Significant increase in sweet corn yield and stover yield was noticed with increasing levels of nitrogen. Higher cob and stover yields were obtained with the application of 125% RDN + FYM @ 10 t ha-1 but it was significantly superior with rest of the treatments. Among the plant densities 60 cm X 15 cm recorded significantly higher nitrogen, phosphorus and potassium uptake in stover and cob over other treatments. The maximum nitrogen, phosphorus, potassium uptake in stover and cob was recorded with the application of 125% RDN + FYM @ 10 t ha-1 at harvest. Among the plant densities 60 cm X 20 cm recorded higher total sugar, starch and amylose content over the other plant densities. Application 100 % RDN + FYM @ 10 t ha-1 recorded significantly higher total sugar, starch and amylose content over rest of the treatments. Among the plant densities 60 cm X 20 cm recorded higher available nitrogen and 60 cm X 25 cm recorded higher available phosphorus and potassium available in soil after the harvest over other treatments. The maximum available nitrogen, phosphorus, potassium in soil was recorded with the application of 125% RDN + FYM @ 10 t ha-1 and it was on par with 100 % RDN + FYM @ 10 t ha-1. The highest gross returns and net returns were higher at a plant density of 60 cm X 15 cm with application of 125 % RDN + FYM @ 10 t ha-1 but the benefit cost ratio was highest at a plant density of 60 cm X 25 cm with application of 100 % RDN.
