Soil physicochemical properties, soil microbial biomass and bacterial community structures in a rice-wheat cropping system subjected to different fertilizer regimes were investigated in two seasons (June and October). All fertilizer regimes increased the soil microbial biomass carbon and nitrogen. Both fertilizer regime and time had a significant effect on soil physicochemical properties and ba...

Rice (Oryza sativa L.) grown on a clay soil in a direct-seeded, delayed-flood system as used in the southern U.S. requires 30 to 60 lb/acre more nitrogen (N) fertilizer to achieve maximal grain yields compared to rice grown on silt loam soils. Seasonal N fertilizer accumulation studies are almost non-existent for rice grown on clay soils. Therefore, a two-year field study was conducted to evalu...

A field study was conducted to determine the effect of organic and mineral-based fertilizers on phytochemical contents in the tubers of two cassava varieties. Treatments were arranged in a split plot design with three replicates. The main plot was fertilizer source (vermicompost, empty fruit bunch compost and inorganic fertilizer) and sub-plot was cassava variety (Medan and Sri Pontian). The am...

A n n u a l W h e a t N e w s l e t t e r V o l. 5 4. The 4-year average for the different fertilizer backgrounds indicated that the least total grain damage by cereal bug larvae was in the block with organic-mineral fertilizer, 5.6 %. Damage in the blocks without fertilizer and with only organic fertilizer was 5.9 and 6.0 %, respectively. Total damage was 4.2–4.9 % in seed with a score of 2, w...

The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...
