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.

    IMPACT OF CLIMATE CHANGE ON CROP WATER PRODUCTIVITY IN GODAVARI EASTERN DELTA
    (guntur, 2022-08-18) KISHORE KUMAR, G.; RAGHU BABU, M.
    Climate change has been considered to have calamitous effects on agriculture and global fresh water. Due to the alteration in climate, crop productivity is being affected adversely resulting in food and livelihood security issues. In view of climate changes, there is a need to increase agricultural water productivity for better management in view of less resources and demand. Proper water management is the only option that ensures a squeezed gap between the demand and supply. For proper planning and efficient utilization of the land and water resources it is necessary to understand the hydrological cycle and estimate the hydrological parameters. Rainfall is the major component of the hydrologic cycle and this is the primary source of runoff. Worldwide many attempts have been made to model and predict rainfall behavior using various empirical, statistical, numerical and deterministic techniques. They are still in research stage and needs more focused empirical approaches to estimate and predict rainfall accurately. This study investigated the Impact of Climate change on Crop Water Productivity using CROPWAT 8.0, AquaCrop, RS&GIS and statistical tools used for climate data. Estimation of mean rainfall over Godavari eastern delta of Andhra pradesh and mandals in the delta has been done using different deterministic methods. Weathercock and Mann-Kendall software were used to compute Rainfall variability and trend analysis on time series data for 30 years period from 1987 to 2016 collected at local stations and departments. Godavari eastern delta comprises of around 15 mandals and the same being considered for the present study. The normal rainfall of the area is 1197 mm. Crop land occupying 70% of the area of Godavari eastern delta. Different thematic maps for the study area have been developed for water resources assessment and for the runoff estimation using SCS-CN. Runoff generated through rainfall with the help of RS&GIS softwares, it is very important in various activities of water management. Results indicated that over 30 years of rainfall-runoff 1996 year showing highest 34.79 % runoff following 2006 with 34.13%. NDVI was derived to observe the change in land productivity for 2011-12 and 2016-17 years using RS&GIS techniques. Vegetation has a distinctive spectral signature that is characterized by low reflectance in visible region of solar optical spectrum as xvi well as high reflectance in infrared (IR) spectrums. The combination of these two spectral regions allows classification of vegetation. In this normalized difference vegetation index (NDVI), Where NIR is the reflectance in near infrared band and R is the reflectance in red band of satellite data. NDVI indicates the vigor of vegetation. Higher NDVI indicates higher amount of green vegetation on ground. NDVI of non-vegetation classes are generally lower than vegetation classes. Vegetation was influenced by time due to land usable changes. There was nearly 11% of change in kharif and whereas it was 30% change in rabi season. Estimation of crop water productivity of rice for prime rice-producing region using CROPWAT and AquaCrop model using soil, climate, crop data and management details. With the help of relatively few conservative crop parameters, AquaCrop simulates final crop yield. The results (WP) for the different years and the different mandals in the study area were varied from 0.75 kg/m3 in 1987-88 to 1.17 kg/m3 in 2016-17 for rabi season. In kharif water productivity is varied from 0.46 kg/m3 in 1990-91 to 0.86 kg/m3 in 2016-17. The average water productivity for 30 years in the study area is 0.68 kg/m3 in kharif and 0.98 kg/m3 in rabi season. WP is higher for the rabi (dry) season than for the kharif (monsoon) season. This is may be due to poor irrigation management practices such as inundation, waterlogging and less sunlight due to cloudiness in crop growth stage. Crop water productivity is highly depending upon weather; therefore, future climate change could affect productivity. Conclusively, CROPWAT 8.0 and AquaCrop models may be used to estimate crop water productivity, water requirements for different cultivars in different climatic conditions to ascertain their minimum water requirements for maximum yields. Thus, further study in Crop water productivity should be carried it out. Key words: Water Productivity, Rainfall-Runoff, CROPWAT, AquaCrop, NDVI, RS&GIS
