Potassium Sources and Rates for Drip Irrigated Polyethylene Mulched Chilli Pepper

Root-shoot regulation and yield of mulched drip irrigated maize on sandy soil

Sandy fields have been reclaimed to exploit the grain production potential in northwestChina. A 2-year statistically replicated field study was conducted to determine the effects ofmulched drip irrigation on soil water, soil nitrate, shoot root growth and yields of maize on asandy field in the Hetao irrigation district. Treatments included border irrigation (BI), fullymulched drip irrigation (F...

Fertigation Frequency for Subsurface Drip-Irrigated Broccoli

Yosef and Sagiv, 1982; Stark et al., 1983; Burt et al., 1995). However, very few studies have shown a benefit Subsurface-drip irrigation and fertigation with fluid N fertilizer of frequent or continuous fertigation compared with sources offers substantial flexibility for N fertilizer management. Fertiless frequent fertigation. Bar-Yosef and Sagiv (1982) gation events can be scheduled as often a...

Relationships between carbon fluxes and environmental factors in a drip-irrigated, film-mulched cotton field in arid region

Environmental factors and human activities play important roles in carbon fixation and emissions generated from croplands. Eddy covariance measurements in a drip-irrigated, film-mulched cotton field were used to analyze the relationships between carbon fluxes and environmental factors in Wulanwusu, northern Xinjiang, an arid region of Northwest China. Our results showed that the cumulative net ...

Irrigation Strategies to Minimize Nitrate Leaching for Drip Irrigated Tomatoes

The Phosphorus and Potassium Fertilizer Value of Two Poultry Litter Sources Used for Flood-Irrigated Rice

Few studies have examined the use of poultry litter as an alternative to inorganic P and K fertilizers for flood-irrigated rice. The objective of this study was to compare fresh and pelletized poultry litter to inorganic P and K fertilizers to document the availability of P and K in poultry litter. Inorganic P and K fertilizers, fresh broiler litter, and pelletized litter were preplant-incorpor...
