Studies on Sprinkler irrigation and its frequency on Productivity And Water use Efficiency For Production Of Wheat

Abstract

newline Irrigation is the backbone of agriculture, irrespective of size of holding, utilizable water resources for agricultural sector are becoming increasingly scarce owing to ever increasing population, abnormalities in weather and depleting ground water resources besides ever increasing competition from household and industrial sectors. Most common irrigation method is by surface where was stage of water is mare by many wags sprinkler irrigation was found the most efficient water saving method. Sprinkler irrigation technology was introduced in the world about 100 years ago but its application increased to larger areas sine 80 years only. newlineEarlier, sprinkler system was used for plantation crops such as tea, coffee, cardamom and other crops raised on hill slopes as a supplementary irrigation during post monsoon periods or dry season, where surface irrigation was not practicable. The concept of sprinkler irrigation has gathered momentum in the recent post because of two important factors viz., impact of climate change resulting in unpredictable showers and long periods of drought and second due to the non availability of labour. newlineSprinkler irrigation efficiency is about 70 % as against 45 % under surface irrigation. Sprinkler irrigation is an advanced technique for water saving and controlling irrigation time and water amount. Looking to these facts, an experiment entitled Study of Sprinkler Irrigation and its Frequency on Production of Wheat was carried out during winter seasons of 2016-17 and 2017-18 at the Instructional Farm, MGCGVV, Chitrakoot, Satna (M.P.). It was essential to maximize the production of wheat growers of this region. newlineThe soil of the experimental field was sandy-loam having pH 7.8, organic carbon 3.8 mgkg-1 available N, P2O5 and K2O 154, 7.9 and 170 kg/ha, respectively. The bulk density of soil was 2.64, field capacity 39.7 and water holding capacity 43.2 and infiltration rate 4.2. The treatment comprised two irrigation methods (surface and sprinkler) and four frequencies of irrigations
