Description |
A field experiment was conducted at research farm of National Agricultural Science and Technology University (ANASTU), Kandahar, Afghanistan during summer season 2016-17. The treatments consisted of two factors, potassium levels (four) 0 kg K2 O/ha, 30 kg K2 O/ha, 60 kg K2 O/ha and 90 kg K2 O/ha and varieties (three) Aftab-e-siya, Aftab-e-surkh, Canadian. All the varieties responded variably to different levels of potassium application in term sof growth, productivity. Based on the results, it is concluded that maximum plant height (136.6 cm) was recorded at 90 kg K2 O/ha. Dry matter accumulation was significantly (P <0.05) higher (115.3 (g)/plant) and at 90 kg K2 O/ ha in Canadian variety. Also maximum sunflower seed yield (2183 kg ha–1) was recorded at 90 kg K2 O ha-1 and it was significantly higher in Canadian variety. Among varieties straw yield was significantly increased in Canadian variety and it was recorded 3782 (kg ha–1). Between potassium levels straw yield was significantly increased at 90 kg K2 O ha–1 it was recorded 3777 (kg/ha). Maximum biological yield (5731 kg/ha) was in Canadian variety. Higher net returns per hectare (109150 AFN) were with 90 kg K2 O/ha in Canadian variety.
