Clean Agritechnique Efficiency Using Compost, Halex-2 and Seaweedon Yield and Quality of Okra

Two field experiments were conducted at the Faculty of Agriculture, (El-shatby), Alexandria University, during the summer seasons of 2017 and 2018, in order to study the effect of compost, Halex2 and Seaweed on okra yield and quality (cv. Turkey). The effects of the treatments on the growth, yield and plant nutrient contents of shoots and fruits were determined. The results showed that using T1,T7, T8, T9, T10 and T11enhanced significantly vegetative growth characters (plant height cm, No. leaves/plant, No. of branches/plant, leaf area index cm, shoot, root fresh and dry weights and nutritional status of plants in leaves and fruits) except T2, T3 gave the highest values in chlorophyll reading of leaves. From data it is obvious that T4 gave the lowest mean values of the given characters. Treatments contained Halex-2 and seaweed increased significantly all morphological characteristics and qualities of okra. The treatments (T7, T9, T10 andT12) lead to increase mineral contents, vitamin C and T.S.S. of fruits compared with T4 treatment. The highest values of total yield were achieved by T9 compared with T4. The use of T1, T8 and T9 were also increased mean values of the No. of fruits/plant, fruit length, fruit diameter and average fruit weight significantly compared with other treatments. This study demonstrated the possibility of producing a good yield of okra safe and healthy without any applying chemical fertilizers via integration of compost, Halex-2 and Seaweed algae as a Clean Agriculture technique.
