Soil moisture is one of the main input parameters in many models for monitoring and predicting crop yield. The ability of mathematical models has allowed correct application of brackish water and selection of management options. The purpose of this research was to evaluate the performance of HYDRUS-2D for simulating soil volumetric water content in a heterogeneous heavy soil under field conditi...
the current study was carried out with the aim of evaluating the effects of pressurized and furrow irrigation methods on the distribution of salinity and moisture in the soil profile. the experimental study design was a split plot layout with three irrigation method including furrow, surface drip (sd) and subsurface drip irrigation (ssd) using two water qualities, municipal effluent (0.509 ds/m...
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
