Nanofertilizers and Seed Storage Periods Role on Increasing the Germination Rate of Okra Crop.

Abstract

An experiment was implemented in the city of Al-Hamzah Al-Sharqi / Al-Qadisiyah Governorate for the year 2023, to determine the effect of a number of nanopotassium concentrations (0, 1 and 2 gm L^-1), and duration of storage of okra seeds (1, 2  and 3 years), on some growth traits of okra seedlings. The results can be summarized as follows, the seed revitalization treatment at a concentration of 1 gm L^-1 was significantly superior, by giving it the highest averages for the germination speed (45.6%), and germination rate (65.6%), compared to the comparison treatment, which gave the lowest averages for this trait, amounting to 37.8 and 57.8%, respectively, while the seed stimulation treatment (2 gm L^-1) excelled on the chlorophyll content and seedling stalk length, the two highest averages were recorded 35.24 spad and 6.143 cm, respectively. Seeds stored for two years outperformed significantly by giving the highest averages for the germination speed (46.7%) and germination rate (74.4%).
