As the industrial hemp ( Cannabis sativa L.) market grows, there is a need for methods to clonally propagate parental breeding stock and new cultivars. Information lacking on vegetative cutting propagation of hemp. We evaluated how environment (intermittent mist vs. subirrigation under humidity dome), indole-3-butyric acid (IBA) formulation (talc rooting powder IBA in solution), concentration (...

a field study was conducted to evaluate the possibility of using water table control techniques in the semi arid region of iran with special attention to its salinity management. the wtm consisted of three subirrigation treatments with water table controls set at 0.3, 0.5 and 0.7 m from the soil surface and a free drainage (fd) treatment. the electrical conductivity (ec) of water was 1.5 ds/m. ...

Nitrate-N (NO3−) effluents from agricultural ecosystems contributing to the degradation of water quality has become a serious environmental problem. A field experiment was conducted in 1996 and 1997 at St. Emmanuel, Que., Canada, to investigate the combined effects of water table management (WTM) and N fertilization on soil NO3− level and denitrification rates in the top soil layer (0–0.15 m). ...

Integrated water management has become a priority for cropping systems where subirrigation is possible. Compared to conventional sprinkler irrigation, the controlling table can lead substantial increase in yield and use efficiency with less pumping energy requirements. Knowing spatiotemporal distribution of depth (WTD) soil properties should help perform intelligent, integrated management. Obse...
