Interaction Effect of Different Concentrations of Nano-Fertilizer (NPK) and Sources of Charcoal on Growth and Yield Parameters of Faba bean (Vicia faba L.)

Abstract

The application of charcoal to agricultural soils is mostly used to improve soil fertility and crop products around the world, but as a scientific researching could be quite neoteric in our region, Kurdistan. Alongside of different sources of charcoal as first factor, nanotechnology was also used as second factor in this research to improve growth and yield parameters of Vicia faba L. The results revealed to the single effect of each of charcoal and Nano-NPK fertilizers and its interaction on studied parameters. Plant height in the control treatment recorded 63.00cm which was dramatically increased to (72.56, 72.64, 75.48cm), respectively in the soil treated with (Local, China and Straw Charcoals), respectively. Additionally, number of pods per plant, pod length and fresh yield per plant were (30.92, 17.59cm, 141.84g) for control treatment, which were increased significantly to (37.81, 18.71cm, 246.34g), for treatments straw charcoal or ash added to the soil, Nano-NPK fertilizers at concentrations of 100 and 200 mg L-1 respectively. Significantly affected on growth and yield parameters. The number of pods, pod length and fresh yield were (23.75, 16.35cm, 83.13g), respectively in the control treatment (C0N0), while in the interaction treatment between charcoal C3 (Straw Charcoals) and Nano NPK N2 (200 mg L-1) caused significant increase in their values to (47.75, 19.07cm, 261.67g).
