Germinated grains are rich source of minerals, water soluble vitamins, enzymes, digestive enzymes and soluble sugars that can be applied as organic foliar on the foliage where photosynthesis takes place. Field experiment was conducted at a field during rice growing season of 2020 to evaluate the effect of sprout grass pea extract on growth and yield of two common traditional local cultivars of rice (Anbarbou and Shamshiri). Irrespective of foliar spray with grass pea extract, seed phosphorus and zinc contents and phytic acid concentration showed a significant genotype variation. Plants sprayed with grass pea sprout extract significantly displayed greater net photosynthesis and water use efficiency. Grain yield, panicle number, grain number, grain weight, fresh and dry matter accumulations and panicle length of plants at harvest were increased up to 7.4%, 23.91%, 7.39%, 4.44%, 18.49%, 16.85% and 26.5%, respectively due to foliar application with grass pea extract. Foliar spraying improved grain Zn content eventually was resulting in lower phytic acid. Foliar spraying with grass pea sprout extract increased grain Zn content from 10.54 µg g-1 to 29.75 µg g-1. Foliar spraying increased grain Zn content in Anbarbou by 1.2-fold in compared to Shamshiri. Grain P content sprayed with grass pea extract increased up to 65.38%, irrespective of the cultivars. Foliar spraying increased grain phytic acid concentration in Shamshiri by 1.65-fold in compared to Anbarbou.
