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.

    ESTIMATION OF CROP WATER REQUIREMENT OF GLADIOLUS (GLADIOLUS GRANDIFLORA L. NEES) UNDER DIFFERENT FIELD CONDITIONS
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) KALYANA SRINIVAS, D; Dr. G. CHANDRAMOULI
    Irrigation is a costly and scarce input in agricultural and plays an important role in increasing food production. It is important that the water requirements of crops are known at different management levels within the irrigated area to accomplish effective irrigation management. In order to apply irrigation water efficiently, the water requirement of the crops are to be estimated accurately. Agriculture being the major water consumer in the ambit of multiple uses of water resources, it emphasizes better knowledge on crop water requirement, planning and scheduling of crops with the internationally accepted state of art of predicting models. When supplied unchecked, every consumer, either a farmer or an industrialist or a domestic users, is tempted to use more water, for no extra gain. In most of the irrigation canals, the farmer in the upper reach of the canals over use the irrigation water leaving the tail end farmers starve for water. In the past, due to non availability of sufficient quantities of water in reservoirs canal water was supplied at much lesser rates than normal rate. Inspite of that, the farmer got good yields of previous years this raised question that whether the farmer has been applying more than the required irrigation water or the estimation of crop water requirements was incorrect. Unscientific and injudicious application water in considerable parts of the canals commands in the state of Andhra Pradesh has also resulted in rise of water table and development of salinity. In order to avoid excess irrigation, there is a need to estimate the crop water requirement accurately and compare them with the actual amounts of water applied in the field. Several computer models are now available to estimate the crop water requirements like CROPWAT, CRIWAR etc. Hence a study was conducted at Precession Farming Development Centre, Agricultural College Farm, ANGRAU, Rajendranagar, Hyderabad. In the present study, the CROPWAT model was used to estimate crop water requirements of Gladiolus in three different field conditions. The methodology consisted of the following main steps; data collection, estimation of water requirements, irrigation scheduling and evaluation of the modeling results. In first step of work, weather parameters were collected on a daily basis. The data of air temperature, humidity, wind speed, solar radiation and precipitation were collected. The data was used for the calculation of reference evapotranspiration using Penman-Monteith equation. Other agronomic parameters acquired during the field work to the study area included the soil characteristics (texture and depth), the period and length of growing season, water use per crop, water availability, irrigation system and its efficiency, the other data of crop productivity under specific input of water and crop coefficient data were collected. The next step of work was the estimation of crop water requirements and irrigation requirements of this crop on a weekly/monthly basis. This analysis was done by using CROPWAT model. This analysis was done by using CROPWAT and model for the actual cropping pattern for gladiolus in the different field conditions. Crop water requirement and irrigation scheduling plan was prepared by average meteorological data and vegetative characters and floral characters are also prepared for three filed conditions. The crop water production function related to yield proposed in the present study. It considers the applied water, crop evapotranspiration and crop yield. Water Production Function was developed for three different conditions by fitting the data into 6 different well established mathematical functions. Crop Water Requirement (CWR) and Gross Irrigation Requirement (GIR) were effectively calculated using Penman-Monteith method using CROPWAT simulation programme and could be adopted for large scale implementation under large field conditions. Crop Water Requirement (CWR) under different field conditions, open condition was estimated to be ranging from 201.8 – 219.8 mm/season, shade net estimated to be ranging from 197.4 – 312.2 mm/season and polyhouse estimated to be ranging from 202.7 – 310 mm/season. To match the irrigation supply vs demand, irrigation water measurements should be made. Study on influence of planting dates on growth and yield post harvest keeping quality in different gladiolus (Gladiolus grandiflorus L.) Different growing conditions were undertaken at Precision farming development center (PFDC), Agricultural college farm, Rajendranagar, Hyderabad. The experiment was laid out in Factorial randomized block design. Highest spike yield was produced by open condition on September 1st and lowest spike yield was produced by polyhouse on October 1st. Study on crop water production function related to yield. WPFs were developed for each experiment by fitting the data into 6 different well established mathematical functions. Among all the six different mathematical functions, best-fit function is third order polynomial based on the maximum value of coefficient of correlation “R2=1”. From this study it is clear that efficient water management becomes crucial and critical in normal or deficit rainfall years. The informal means of ‘adjusting’ irrigation water in such years, at field level, was not scientifically documented or explained. The method adopted in this study provides the solution which is scientific and at the same time practical.
