Abstract
Chilli (Capsicum annuum L.), marigold (Tagetes erecta L.), mustard (Brassica juncea (L.) Czern.) and pigeon pea (Cajanus cajan (L.) Millsp.) were raised in pots containing the soil amended with various treatments of zinc sulphate (control, 50, 100, 150, 200 and 250 mg kg -1 soil). Five replicates were maintained for each treatment. The effect of zinc on nutrient contents of nitrogen, phosphorus, potassium, iron, manganese, zinc and uptake and accumulation of zinc on chilli, marigold, mustard and pigeon pea were analyzed on 45 th day. From the present investigation, it was concluded that the 50-100 mg kg -1 level of zinc in the soil was beneficial for the growth of chilli, marigold, mustard and pigeon pea plants. The level of zinc in the soil above 150 mg kg -1 proved to be toxic. The results indicated that the 50-100 mg kg -1 zinc level can be applied for increasing the growth and yield of chilli, marigold, mustard and pigeon pea plants. Further the phytoremediating role of mustard on zinc polluted soil is high and chilli, marigold and pigeon pea have less phytoremediating ability.
