The study was conducted with dug out farm pond at Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during 2010-11 to 2013-14. Reutilization study on protective irrigation to soybean was conducted during kharif 2013. On an average, runoff of 12.43% and harvesting potential of 11.10% of rainfall was observed from the catchment area of 1.60 ha during experimentation period. An average total storage loss of 1718.10 m 3 was observed during the period from July to December comprising an evaporation and seepage losses of 150.59 m 3 (8.67%) and 1567.51 m 3 (90.29%), respectively. One protective irrigation of 5 cm to soybean at maturity stage during prevailing critical dryspell, increased soybean grain yield by 30.87%. An average irrigation potential, on the basis of monthly storage volume of farm pond during 2010 and 2013, was observed as 0.87 ha.
Morphometric analysis of Pingalgarh watershed in Maharashtra state was carried out using remote sensing and GIS techniques for 1977 and 2016. Detailed drainage map was prepared from LISS-IV high resolution satellite image of 20th November 2016 to assess the present situation and from Geo-referenced toposheet on 1:50,000 scale for the year 1977 to bring out the past condition. These maps were used for morphometric analysis and also for runoff estimation. Low drainage density values indicated that the area was underlain by moderately impermeable sub-surface material. Circularity and elongation ratio showed that the watershed had elongated shape. Due to change in land use, the total stream length in the watershed had reduced. The low to moderate value of basin relief indicated gravity of water flow, moderate infiltration and runoff condition of the study area. The length of overland flow indicating the long flow path with moderate ground slope, reflecting the areas associated with moderate runoff and infiltration. Low values of relief are the characteristic features of less resistant rocks of the area. Due to change in land use and cropping pattern over a period of time, the time of concentration was reduced in the later stage resulting in increase in peak runoff rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
