Effect of supplementary irrigation and bio-fertilization on wheat yield productivity under rainfed conditions [electronic resource].

Includes references.

Two field experiments were carried out during the two successive growing seasons (200612007 and 2007/2008) at ElHammam fitrm, Marsa Matrouh, North Western Coast of Egypt, to study the effect of supplementaJy irrigation schedule depth (mm) and bio-fertilization on wheat yield productivity. The study included two regimes of bio-fertilizers (without bio-fertilization and bio-fertilization with Microbein as Pseudomonnas sp., Azotobacter sp., Azospirillum sp. and B. megaterium) and four irrigation schedule depth (mm) (without supplementary irrigation(rainfed), supplementary irrigation by 60 mrn/fed, supplementary irrigation by 90 nnnlfed and supplementary irrigation by 120 nnnlfed), all under rainfed conditions. The obtained results could be summarized as follow: !-The measurement yield and its components i.e., plant height, number of tillers per plant, number oftillers/m2, number of spikeslm2, spike length, number of spikeletes/apike, number of grain/spike, biological, grain and, straw yields,! 000-grain weight; and tillering index were significantly increased by adding bio-fertilizer compored to the control. 2-Adding 120 nnnlfed., as an irrigation depth, gave the highest values markedly for plant height, number oftillesr/plant, number of tillerslm2, number of spikes/m2 spike length, number of spikelet/spike, number of grains/spike, biological, grain, straw yields, I 000-grain weight, and tillering index. 3-COnceming the effect of interaction between the two factor, bio fertilizer and supplementary irrigation with 120mm/fed gave the highest values for some characters urnder study i.e; number of tillers per plant. number oftillers/m2, number of spikelm2 ,number of grain/spike, biological, grain and straw yields, and tillering index, which were significant in both seasons, while there insignificant differences for plant height and spike length, W.U.E. and number of spikelet /spike Generally, it can.be concluded that cultivation the bio-fertilized wheat c.v shaka 93 at EI,Hanunam farm at North Western Coast ofEgybt gave high yield and yield characters under rainfall conditions or with supplementaJy irrigation or 120 nnnlfed. at North Western Coast of Egypt
