Nutrient Composition, Antioxidant Andantiproliferative Properties of Chilli and Tomatocultivated by Fertigation and Conventional Methods

Chilli (Capsicum annuum) and tomato (Lycopersicon esculentum) are two fruittype vegetables which are commonly found in multiethnic Malaysians' daily menu. They are widely consumed, easily available and edible in a variety of ways. Chillies and tomatoes which are found in the local markets ar...

description Chilli (Capsicum annuum) and tomato (Lycopersicon esculentum) are two fruittype vegetables which are commonly found in multiethnic Malaysians' daily menu. They are widely consumed, easily available and edible in a variety of ways. Chillies and tomatoes which are found in the local markets are usually grown by farmers using the conventional way of cultivation, i.e. soil-based method. Fertigation is a relatively new cultivation technique in Malaysia which uses nutrient solution for the growth of the plants instead of relying on the soil as the nutrient provider.
