EFFECT OF FOLIAR SPRAY (ALGAE EXTRACT) , COMPOST AND BIO FERTILIZER ON WHEAT PRODUCTIVITY

A field experiment in the form of split-split plot design with three replications was conducted at Mashtool ElSouk, Al- Sharkia Governorate, Egypt during 2016/2017 and 2017/2018 growing seasons. The aim of study is to determine the effect of different foliar spray (Algae extract) level (without, 0.50 and 0.75 cm/l) and different compost levels (without, 6 and 8 ton/fad) in absence or presence of biofertilizer on wheat yield
The results can be summarized as follows:
1- Data indicate that there are significant differences of foliar concentrations as algae extract, compost levels and bio fertilizer for all studied characters in the two seasons.
2- Spraying wheat plants with algae extract at the highest concentration (0.75 cm/L) gave a significant increase of most yield components as well as grain straw and biological yields compared to the other two concentrations with exception of grain no./spike which no addition of algae extract recorded the highest significant values of all characteristics in both seasons
3-The addition  of compost at the highest rate (8 ton/fad) resulted in a significant increase of most yield components and wheat yields comparing with the other two rates except the parameter of grain no./spike as mentioned before . Such results were the same in two seasons.
4-The addition of biofertilizer caused the highestsignificant values of the above mentioned characteristics except for grain no./spike which the highest values of such character resulted from no addition  of biofertilizer. The two seasons had the same results.
5-It must be mentioned that the interaction effect among the three factors under study took the same trend of such individual factors where the application of algae extract at the level of 0.75 cm/L and compost level 8 ton /fad as well as applied biofertilizer resulted in the highest significant values of all parameters mentioned before, with exception of grain no./spike which was the highest with no addition of any factors under study, such results were similar in both seasons.
