Effect of Chicken Manurefertilization, Active Dry Yeast Foliar Spray Concentrations and Their Interaction on Lavander (Lavandula Officinalis, Chaix) Plants Growth and Productivity

Abstract

A field experimental laid out at a completely randomized block design at the experimental farm of Fac. of Environ. Agric. Sci., Arish Univ., El-Arish, North Sinai Governorate, Egypt during the two successive summer seasons of 2017/2018 and 2018/2019, to study the effect of chicken manure (ChM) as N fertilizer source, dry yeast spraying concentrations and their interaction on vegetative, yield and chemical composition of lavender (Lavandula officinalis). Results showed that fertilization lavender plants with 100 % from the recommended N rate as chicken manure (ChM) recorded the maximum growth, yield and chemical constitutes of lavender. Moreover, application of dry yeast at 200 ppm increased significantly lavender growth, yield and chemical constitutes. For the interaction between chicken manure (ChM) as N fertilizer source and dry yeast concentrations the same trend were observed when plants fertilized with 100 % from the recommended N rate as chicken manure (ChM) and sprayed with 200ppm dry yeast.
