Abstract

Abstract
A greenhouse study was conducted to compare the effects of ordinary iron oxide (0.02-0.06 mm) and nano iron oxide (25-250 nm) and five levels of both iron oxides (0, 0.05, 0.1, 0.5, and 1.0 %w/w) and two levels of sulfurous granular compost (MSW) (0 and 2% w/w) on plant height, spike length, grain weight per spike, total plant dry matter weight and thousands grain weight of wheat. The experimental factors were combined in factorial arrangement in a completely randomized design with 3 replications. Results showed that nano iron oxide was superior over ordinary iron oxide in all parameters studied. Fe concentration, spike length, plant height, grain weight per spike, total plant dry weight and thousands grain weight showed increasing trend per increase in both of iron oxides levels. Also, all parameters studied in sulfurous granular compost (MSW) treatment were superior over granular compost without sulfurous (MSW). This increase in all parameters were significantly higher when urban solid waste compost coated with sulfur coupled with nano iron oxide compared to urban sulfurous granular compost (MSW) along with ordinary iron oxide.
