Evaluation of foliar application with Nano fertilizer ( Super micro plus) in different times on availability and uptake of some micronutrients and some quality properties ofRice (Oriza sativa L.)

A field experiment was conducted in Al – Najaf Al Ashraf Governorate during summer season 2017 to study the effect of foliar application with Nano fertilizer with three levels ( 0 , 1 and 2) gm L-1 ( super micro plus that contains (5% N , 3% P , 3% K , 4.5% Fe , 8% Zn , 6% Ca , 6% Mg , 0.7% Mn , 0.65 % Cu , 0.65% B and 0.1% Mo ) and three stages ofapplication at tillering stage , booting stage and flowering stage in Fe , Zn , Cu and Mn availability , uptake in straw , protein and white grains present of rice (Oriza sativa L.) Amber 33 variety . A experiment was conducted in accordance with to RCBD with three replicates. The following results were obtained :1- Superior the level 2g L-1 Nano fertilizer in availability of Iron , cooper & manganese in soil ( 4.1 & 1.70 & 3.22 ) mg kg-1 soil respectively . uptake of Iron , zinc , cooper & manganese in straw ( 0.504 & 0.107 &0.080 & 0.289 ) kg h-1 .and protein ,white grains percent ( 8.20 & 67.97 ) % respectively . 2- Superior stage of adding Nano fertilizer in flowering stage on manganese availability in soil ( 2.90 ) mg kg-1 soil ,and cooper uptake and manganese in straw ( 0.055 & 0.252 ) kg h-1 respectively . 3- Superior the interaction between levels of nano fertilizer application and stage of foliar application in level 2gm L-1 in flowering stage in availability of manganese ( 3.44 ) mg kg-1 soil . Iron uptake, cooper uptake and manganese (0.529 & 0.082 & 0.298 ) kg h-1 respectively , and protein present ( 8.41 ) .
