Influence of organic, inorganic nitrogen fertilization and potassium levels on wheat plant grown in newly reclaimed soil [electronic resource].

Includes references.

Two field experiments were carried out at El- Areish Agricultural Research Station, North Sinai Governorate during the two winter growing seasons of 2006/2007 & 2007/2008 to study the effect of organic and inorganic nitrogen fertilization as well as potassium levels (24 and 48 kg K₂O /fed.) on yield components, grain & straw yield and chemical composition of wheat plant in calcareous soils. Results can be summarized as follows: 1- Generally, in most cases, the treatment of compost of chicken manure (CCM) with addition of soaking compost with drip irrigation (SCD) or/and foliar application of soaking compost (FSC) on wheat plant gave the highest significant values on all parameters under study in two seasons. On the other hand, the lowest significant values were obtained when sole mineral fertilizer was applied in both seasons. 2- The higher level of potassium achieved the highest significant values of plant height in first season, grain & straw yield in seasons as well as N % in grain at both seasons as well as P & K % in wheat grain and straw yield in second season compared with the lower one. 3- In most cases, there were no significant interaction effects between the organic and inorganic nitrogen fertilization and potassium levels on all parameters under study in both seasons.
