Strawberry (Fragaria ×ananassa Duchesne) is a high-value cash crop that benefi ts from preplant soil fumigation with methyl bromide (MB) and chloropicrin (CP). Methyl bromide will be banned in the U.S. and other developed countries by 2005 for most uses. Potential alternative chemicals to replace methyl bromide for soil fumigation include CP, 1,3-dichloropropene (1,3-D), and methyl isothiocyana...
the objectives of this study were to evaluate the effects of nitrogen fertigation frequency on lint yield, lint properties, chlorophyll content (spad readings), and the photosynthesis rate (pr) of cotton. this study was carried out in the southeastern anatolia region of turkey in 2011 and 2012 with drip-irrigated cotton. the maximum lint yield (1,856 kg ha-1) was obtained with one lateral for e...
in order to study of drought tolerance levels in some wheat lines and cultivars based on uniform regional wheat yield trial (urwyt-m-75) an experiment was carried out using a strip plot design based on complete block design with 3 replications for two years (1998-2000) in torogh agricultural research station (mashhad, iran). the main plots (horizontal factor) were 3 levels of irrigation: 10, 20...
effect of subsurface irrigation with porous clay capsules on quantitative and quality of grape plant
introduction: maintaining soil moisture content at about field capacity and reducing water loss in near root zone plays a key role for developing soil and water management programs. clay pot or porous pipe is a traditional sub-irrigation method and is ideal for many farms in the world’s dry land with small and medium sized farms and gardens and is still used limitedly in dry lands of india, ira...
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...
