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.

    STUDIES ON RICE PRODUCTIVITY UNDER MODIFIED SRI IN THE FIELDS OF CHITTOOR DISTRICT
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) NAGA JYOTHI, M; Dr. M.V. RAMANA
    Field experiments were conducted for assessing productivity in rabi under modified SRI in the fields of Chittoor District. The investigations comprised of two sets of field experiments conducted at Agricultural Research Station, Perumallapalli. In both the experiments, the test variety was BPT 5204. Experiments were designed with RBD with four replications. The treatments comprised of combination of 10 different nursery bedding materials and five intra row spacing planting patterns. The water applied was also documented for estimating water use efficiency (WUE). The highest PH value was found in with rice husk as nursery bedding material as 7.9 followed by groundnutshell (7.8) and highest EC was found with groundnutshell (GS) as 5.1ds/m, whereas lowest EC was recorded in rice husk (RH) as 0.95ds/m. However, the highest N value was found in groundnut shell as 1.7% followed by FYM (1.42%), whereas the lowest N value was recorded for rice husk as 0.48%. Vermicompost (0.72%) followed by groundnutshell (0.48%) and rice straw (0.26%) were considered to have the highest and lowest P values. Similarly, 1.9% and 0.48% were recorded as the highest and lowest K values for rice straw and rice husk respectively. Finally it is concluded that using the entire nursery bedding materials and it is not only conserves the soil but also adds nutrients to the soil and leads to reduction in the requirement of fertilizers and so these materials were mixed with soil in different combinations and used for rising nursery. It is also concluded that transplanting of seedlings from younger stage provides sufficient nutrients for vegetative growth and also for reproductive phase which ultimately leads to increased plant height. Highest and lowest numbers of tillers were found to be 6.75 and 5.00 at 15 DAT in T10 and T2 respectively. Similarly, 14.50 in T8 and 9.50 in T2 at 30 DAT and 36.75 in T3 and 23.75 in T10 at 60 DAT were considered to be the highest and lowest number of tillers respectively. Highest panicle length was observed in T9 as 20.90cm where as the lowest panicle length was observed in T1 and T3 as 19.37cm. in T2 and T10, 39.45 and 20.80 were considered to be the highest and lowest number of productive tillers. Similarly, number of unproductive tillers i.e., 3.62 in T6 and 2.37 in T1 and T7 as the highest and lowest values were observed. Filled grains and unfilled grains also had the highest and lowest values i.e 186.58 in T2 and 144.53 in T6 and 24.32 in T5 and 10.90 in T8 respectively. Finally, highest and lowest values for total grains were found to be 200.45 and 158.27 in T4 and T6 respectively. Finally, it has been concluded that spacing and nutrients available in different bedding materials helps the plants to grow healthy, which has more number of tillers and increases the yield. Highest grain yield 4858.54 kg/ha in T8 and lowest grain yield, 2212.60kg/ha in T6 were observed. Similarly, 5081kg/ha and 2380 kg/ha in T1 and T6 were considered to be the highest and lowest values for straw yield. T8 and T6 possessed the highest and lowest thousand grain weight values as 13.86 gm and 10.58 gm respectively. In transplanting experiment, panicle length, filled grains and root length possessed the highest and lowest values in different treatments i.e 20.77 cm and 19.59 cm in T3 and T1,25.31 and 153.79 in T4 and T5 and 11.96 cm and 9.17 cm in T3 and T5 respectively. In the same way, highest and lowest grain yield were observed in T3 and T5 as 7267.50 kg/ha and 5831.00 kg/ha respectively. Straw yield was highest in T4 and lowest in T5 and had the values of 8872.50 kg/ha and 6332.50 kg/ha respectively.13.88gm and 11.34 gm were recorded as the highest and lowest thousand grain weight values were in T3 and T5. Higher water use efficiency (5.69kg/ha-mm) was recorded in mechanized paddy crop compared to conventional method i.e., (2.31 kg/ha-mm). It was also observed the increase in the water use efficiency as (3.38 kg/ha-mm) and concluded that higher yield (15.78%), high water use efficiency (57%) and reduced water consumption (49.48%) were possible through machine transplanted rice production system. Human labour is one of the most critical components in rice production system and also a major cost influencing factor of any crop cultivation. The total labour requirements for mechanised and conventional paddy production were 26 man days and 85 man days per hectare respectively. The total variable costs per hectare mechanised paddy and conventional paddy were Rs 39755/- and Rs 41580/- respectively. On an average, the yield advantage of 4.75 quintals per hectare was observed in mechanised compared to conventional paddy. The higher productivity on mechanised paddy farms were relatively better and timely management practices (like young seedling transplantation, aerated field with more row space and mechanical weeding) were followed. The by products from the mechanised and conventional fields were 2.5 and 2 tonnes respectively. Mechanised paddy farmers were able to secure a net income Rs 1.81/- per every rupee of expenditure. While, the convectional paddy farmers realised Rs 1.42/-. Key Words: MSRI, Growth Parameters, Yield Parameters, Economics
