| Abstract | ||||
| Experiments were conducted over two successive growing seasons (1997/98 and 1998/99) at Kaha research station, Hort. Res. Institute. Artichoke plants were sprayed with GA3 at concentrations of 50, 100, 150 and 200 ppm in combination with 4g /l Nutramin-6 contains manganese 8%, iron 7.5%, copper 3.5, zinc 4.5%, boron 1.5%, molybdenum 0.05% and sulfur 15%. Plants were treated with 4g /l alone and water only as a control. The treatments and water were applied twice to the foliage at 50 and 65 days after planting. Artichoke plants treated with GA3 in combination with micronutrients and micronutrients alone gave significant earliness in head production 4 weeks before control. Early yield (November-February) was significantly greater from plants treated with GA3 + micronutrients than micronutrients treatment and control plants. Head, receptacle diameter and weight were more than the control in both seasons for early heads. Other variables such as T.S.S, reducing, non reducing sugars, inulin and phenols did not response significantly to the applied treatments. | ||||
