| Popis: | In order to study the effects of putrescine (Put) and humic acid (HA) on growth, yield and pod quality of okra (Abelmoschus esculentus L. 'Kano') under deficit irrigation stress, the field experiment was conducted in split plot based on randomized complete block design with three replications. Three different irrigation regimes (33, 66 and 100% ETc) and foliar application of Put (0, 0.5, 1 and 2 mM) and HA (0, 150 and 300 mg.l-1) were conducted. The results showed that deficit irrigation significantly decreased growth, yield and vitamin C content. Significant (P>0.05) increase in growth and yield was observed with the application of both HA and Put. The highest plant growth was obtained whit application of HA 300 mg.l-1 and Put 1mM under irrigation 100% ETc. Also, the maximum yield was observed whit foliar application of HA 300 mg.l-1 and Put 1mM under irrigation 100% ETc. Application of Put and HA at irrigation 100% ETc and HA 150 and 300 mg.l-1 and Put 1mM under deficit irrigation 66% ETC had highest effects on vitamin C content. According to the results, application of HA 300 mg.l-1 and Put 1mM can be proposed to improve growth and yield of okra. |
