Abstract
AbstractCapillary rise from groundwater is known as the upward flow of moisture in the soil and is a significant component of soil water balance, specifically in the occurrence of a shallow groundwater table (SGT). Extraction of moisture from the SGT needs a proper understanding of the capillary rise. Various soil, crop, and environmental parameters possess a significant effect on the capillary rise. The objective of the study is to identify the impact of crop parameters on the capillary rise by performing field crop experiments on crops i.e., Wheat, Maize, Indian mustard, and Pea. Experiments are conducted using a Lysimetric setup on an agricultural farm at Hamirpur, Himachal Pradesh, India. Various models are considered to investigate the influencing parameters for capillary rise due to the crops for local climatic conditions. Regression analysis and performance indicators are used to perform analysis for the present study. Crop parameters (root depth, plant height, leaf area index), crop evapotranspiration, and soil moisture variation are found to affect capillary rise from the SGT. The proper understanding and estimation of capillary rise will supplement in optimized usage of moisture for irrigation purposes in areas with a SGT.KeywordsCapillary riseWater tableCrop evapotranspirationPlant transpirationSoil moisture
