Effect
Increased produce quality
Kelpak treated 8-weeks old Tomato, cv. Rana, grown under a 60 % shaded cloth had on average a higher total fresh weight, a bigger leaf surface and more flowers as compared to the untreated control. The soil drench applications at the 2 highest doses (0.4 and 1 %) gave significant better results, the foliar application didn't have an effect. Kelpak treated Tomato, cv. Rana grown under a 60 % shaded cloth had on average a higher fresh weight of the 1st harvestable fruit (foliar spray gave best result), had a higher total fruit fresh weight (soil drench best results) and had a higher average fruit fresh weight (foliar spray better) as compared to the untreated control.
