Abstract
A field experiment was carried out in winter season 2019 using broad bean. This study is to evaluate the effect of P and K as Nano fertilizes as foliar application at rate 0, 250 and 500 ppm for P, and 0, 150 and 300 ppm of K on thegrowth and the productivity of broad bean grown in sandy soil at Baloza Station-North Sinai of the Desert Research Center, Egypt, located at 31̊ 3ʹ 0" N32̊ 36ʹ 0" E. The treatments (P) and (K) were added as foliar spray after 25, 50 and 75 (DFS). Results indicated that the yield components of broad bean were improved with increasing P application. The K application took the same behavior of P where the spraying 500 and 300 ppm of P and K respectively, showed the higher effect on the yield parameters than the other levels. The nutrients concentration increased with increasing rates application of P and K which gave higher values than control treatment. Also N, P and K uptake had the same behavior as nutrients concentration where they affected significantly by spraying plants with P and K. The most efficient treatment was found when using the third rate of both nano P and K fertilizers which achieved 2.457, 1.470 and 3.927 ton fed-1 of straw, seeds and biological yield of broad bean, respectively. With increasing foliar application nano fertilizes of P and K single or in combination slightly increased the amount of N, P and K in soil after harvesting.
