Abstract
To study the effect of Fe and Zn on soybean dry matter yield and nutrient accumulation, experiments were conducted in pots at Nuclear Institute for Food and Agriculture ( NIFA) during 1983 and NWFP Agricultural University, Peshawar during1984 on clay loam and silty clay loam soil. The treatments included 0,7,14 kg Iron (Fe) hcr1 and 0,5,10 kg zinc (Zn) ha-1 alone and in combination. Dry matter yield increased in response to single application of Fe and Zn and their combined application resulted in still higher dry matter. Nitrogen fixation efficiency increased with single application of Fe and Zn and their combined application resulted in much higher nitrogen efficiency. There was positive correlation between dry matter yield and total nitrogen recovery.
