Response of Mung Bean Crop to Different Levels of Applied Iron and Zinc

Abstract

Fertilization of Mung bean ( Vigna radiata L) is one of the most crucial management technique which effects crop growth and yield. Therefore the present study was carried out at Agricultural Research Station Kohat under rain fed conditions during spring 2017, to assess the response of mung bean ( Vigna radiate L.) to three levels of iron (0, 2 and 5 kg ha -1 ) and three levels of zinc (0, 5 and 10 kg ha -1 ). The experiment was laid out in randomized complete design with split plot arrangement and replicated three times. The results revealed that application of Fe at the rate 5 kg ha -1 and Zn at the rate 10 kg ha -1 significantly increased biological yield, grain yield, straw yield, nodule numbers and weight by 5624 kg ha -1 , 968 kg ha -1 , 4655 kg ha -1 , 35 and 0.67g respectively whereas the interaction was found non- significant. The nitrogen content in grains and straw was also significantly increased by 2.22% and 3.56% respectively with application of Fe at 5 kg ha -1 and Zn at 10 kg ha -1 , however their interaction was also found non-significant. Similarly the plant nitrogen uptake was also significantly increased by 323.33 kg ha -1 with application of Fe at 5 kg ha -1 and Zn at 10 kg ha -1. It was concluded that Fe and Zn enhanced mung bean productivity.
