Abstract

Fertilization is an important and limiting factor for growth and tuber production of potatoes crop because plants non adsorption amounts of nutrients from the soil. Data obtained the tea compost spray or tea compost fertigation single or mixed with mineral-N. Resulted in grand mean the highest tuber yield of potatoes tea compost methods, the value of tuber yield value (42.34 tan ha -1) which relatively increased by about 15.68%, 11.31% over the untreated addition compost to soil and tea compost fertigation.Also data show that grand mean the highest shoot dry weight of potatoes foliar compost tea methods, the value of tuber yield value (4.79 tan ha -1) which relatively increased by about 41.54%,24.43% over the untreated addition compost to soil and tea compost fertigation. Also data show under methods, fertigaion compost tea, with treatment 50% compost tea+ 50% mineral –N seems to be the best ones in nitrogen uptake by tuber potato plant (131.24 kg ha-1). the compost tea fertigation, % Ndff, Ndfcompost in tuber was much higher for tea compost fertigation (57.74 kg ha-1) ,(56.62 kg ha -1 )than for compost tea foliar methods (50.21 kg ha-1),(51.84 kg ha-1) and compost addition to soil (33.02 kg ha-1) , (27.82 kg ha-1) respectively . The percentage nitrogen use efficiency (%NUE) by tuber ranged from %9.17 to %16.27 due to (MA1)+R2 and 100 % MF , respectively.
