Ms. Munazza Rafique is working as Soil Specialist in Water and Power Development Authority, Pakistan. She has done her M.Sc (Hons) in Soil and Environmental sciences from UAF. Her subject of interest is Soil Fertility and Plant Nutrition.
This study is primarily related to use humic acid as a soil conditioner and calcium carbide as plant growth regulator. Humic acid improves soil organic matter, water holding capacity, and nutrient use efficiency, whereas calcium carbide is potential source of two gases, acetylene and ethylene. Acetylene acts as nitrification inhibitor while slowly releasing ethylene works as phytohormone. The study shows that plant height, number of flowers, number of green pods per plant, green pod dry weight, shoot and root dry weight, nutrient uptake in fruit of okra plants were positively affected by calcium carbide and humic acid.
