Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermon...

in vitro and greenhouse studies were conducted to investigate the possibility of an interaction between two systemic insecticides of: thiodicarb (larvin df 80) and imidacloprid (guacho sw 70), and seedling disease organisms of: rhizoctonia solani, fusarium moniliforme and pythium ultimum. when in vitro concentrations of imidacloprid and thiodicarb were applied, a fungistatic activity occurred. ...

Arsenic contamination in a large area of agricultural fields on the Guandu Plain of northern Taiwan was confirmed in a survey conducted in 2006, but research concerning the relationship between bioavailable As concentrations in contaminated soils and crop production in Taiwan is not available. Pot experiments were conducted to examine the growth and accumulation of As in four vegetable crops gr...

The effect of Gibberellic Acid (GA3) on Jerusalem cherry (Solanum pseudocapsicum L.) was evaluated at pot cultivation conditions. This study was performed in factorial test based on complete random design plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 at 0, 100, 200 and 400 mg.L-1 levels...

Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
