摘要

The micronutrient required in minute quantity and their deficiency leads to diminished growth and yield of crops. The effect of soil application of Zinc (Zn), Boron (B) and Microtone (MT) on growth, chlorophyll contents, mineral profile and yield components were investigated in rice at Chakkanwali Reclamation Research Station District, Gujranwala, Pakistan?in the year?2011. Seven treatments which includes Zn 33%?at?3 kg/acre, Zn 33%?at?6 kg/acre, B 11.3%?at?1.5 kg/acre, B 11.3%?at?3 kg/acre, Zn + B?at3 + 1.5 kg/acre, Zn + B?at?6 + 3 kg/acre and MT + Zn 6% + B + Fe + Mn + Cu 1% each?at?500 ml/acre, and F0?considered as?the?control were used. The results reveal that foliar application of Zn and B (Zn + B?at?6 + 3 kg/acre)?were?proved as the best balanced fertilizer dose for higher growth and yield response. The plant height, tiller/plant, panicle length, kernels/plant, filled kernel/plant, productive kernel, straw, paddy and biological yield increased up to 29.75, 38.40, 28.19, 25.81, 36.52, 38.52, 32.47, 38.27 and 31.79%, respectively. The chlorophyll contents, B and Zn contents in rice plant also increased significantly as compared to the control. However, the B, Zn and MT application reduced the amylase and protein contents of rice plant at all treatment levels.
