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 DIFFERENT SOURCES AND METHODS OF SILICON APPLICATION ON DIRECT SOWN RICE
    (Acharya N.G. Ranga Agricultural University, Guntur, 2021-12-09) BHAGYA LAKSHMI, MARURI; LATH, Dr. M.
    A field experiment entitled “Effect of different sources and methods of silicon application on direct sown rice” was conducted at Agricultural College Farm, Bapatla during kharif, 2019-2020. The experimental soil was sandy clay in texture, slightly alkaline in reaction and non-saline. The soil was low in organic carbon, low in available nitrogen, medium in available phosphorus, high in available potassium, medium in silicon and sufficient in all available cationic micronutrients (Zn, Fe, Mn and Cu). The experiment was laid out in randomized block design (RBD) with nine treatments replicated thrice. The treatments consisted of T1- 100% RDF (180:60:40 N-P2O5-K2O kg ha-1 through Urea, SSP and MOP); T2- 100% RDF + soil application of 100 kg ha-1 Calcium Silicate; T3- 100% RDF + soil application of 200 kg ha-1 Calcium Silicate; T4- 100% RDF + soil application of 20 kg ha-1 Silixol granules; T5- 100% RDF + soil application of 40 kg ha-1 Silixol granules; T6- 100% RDF + foliar spray of Stabilized Silicic acid @ 0.4% at 30 & 60 DAS; T7- 100% RDF + foliar spray of Stabilized Silicic acid @ 0.4% at 30, 60 & 90 DAS; T8- 100% RDF + foliar spray of Potassium Silicate @ 0.8% at 30 & 60 DAS; T9- 100% RDF + foliar spray of Potassium Silicate @ 0.8% at 30, 60 & 90 DAS. A common dose of nitrogen @ 180 kg ha-1 was applied in the form of urea in three equal splits i.e 1/3 as basal, 1/3 at active tillering and 1/3 at panicle initiation stage. Phosphorus in the form of single super phosphate 60 kg ha-1 was applied as basal just before sowing. A common dose of 40 kg K2O ha-1 was applied as muriate of potash, in two equal splits as half at basal and half at panicle initiation stage by considering the plot size. Different sources of silicon were applied as per treatments. The influence of various treatments on growth attributes, yield attributes, yield were recorded. Nutrient content, uptake and soil properties (Physico-chemical properties and available nutrients) were determined by standard procedures at different stages. xvii The soil properties like pH, EC, organic carbon, cation exchange capacity were not significantly influenced by application of different silicon sources. Soil chemical properties like available nitrogen, phosphorus, potassium, silicon significantly increased with application of 100% RDF + soil application of 200 kg ha-1 calcium silicate (T3) and it was on par with 100% RDF + foliar application of stabilized silicic acid @ 0.4% at 30, 60, 90 DAS (T7), 100% RDF + foliar application of potassium silicate @ 0.8% at 30, 60, 90 DAS (T9) and 100% RDF + soil application of 40 kg ha-1 silixol granules (T5) whereas available micronutrients like Fe, Mn, Zn and Cu non-significantly increased by application of different silicon sources and methods. Growth attributes like plant height, number tillers per hill, SPAD chlorophyll values, leaf area index and yield attributes like test weight, harvest index, dry matter production as well as yield (straw and grain) significantly increased by application of T3 treatment (100% RDF + soil application of 200 kg ha-1 calcium silicate) and it was on par with T7 (100% RDF + foliar application of stabilized silicic acid @ 0.4% at 30, 60, 90 DAS), T9 (100% RDF + foliar application of potassium silicate @ 0.8% at 30, 60, 90 DAS) and T5 (100% RDF + soil application of 40 kg ha-1 silixol granules). Plant nutrient content (N, P, K, Si) and its uptake at tillering, panicle initiation, straw and grain at harvest stage of direct sown rice was significantly increased with application of 100% RDF + soil application of 200 kg ha-1 calcium silicate (T3) and it was on par with 100% RDF + foliar application of stabilized silicic acid @ 0.4% at 30, 60, 90 DAS (T7), 100% RDF + foliar application of potassium silicate @ 0.8% at 30, 60, 90 DAS (T9) and 100% RDF + soil application of 40 kg ha-1 silixol granules (T5) whereas content and uptake of micronutrients like Fe, Mn, Zn and Cu nonsignificantly increased by application of different silicon sources. Quality parameters like grain protein and total carbohydrate content significantly increased by application of T3 treatment and it was on par with T7, T9 and T5. The T3 (100% RDF + soil application of 200 kg ha-1 calcium silicate), T7 (100% RDF + foliar application of stabilized silicic acid @ 0.4% at 30, 60, 90 DAS), T9 (100% RDF + foliar application of potassium silicate @ 0.8% at 30, 60, 90 DAS) and T5 (100% RDF + soil application of 40 kg ha-1 silixol granules) treatments significantly increased the soil chemical properties, plant nutrient content and its uptake, growth and yield attributes, yield as well as quality parameters and these significantly increased treatments like T7, T9 and T5 are on par with T3. Overall, the results suggested that 100 % RDF + soil application of 200 kg ha-1 calcium silicate enhanced the soil available nutrients and yield of direct sown rice. But the highest B: C ratio was obtained with the foliar application of 0.8 % potassium silicate at 30, 60 and 90 DAS which also gave the significant increment in soil properties and as well as yield of direct sown rice. So, taking into consideration of three aspects like improving soil properties, yield and B:C ratio, the foliar application of potassium silicate at 30, 60 and 90 DAS was the best option for the farmers.
