Responses of Phosphorus and Zinc on Growth and Yield in Chickpea (Cicer arietinum L.)

The investigation was taken up at Student's Instructional Farm, Nawabganj at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, (U.P.) India, during Rabi 2020-21. The 2 factors in sixteen treatment combinations viz., P0Zn0 (control), P0Zn2.5, P0Zn5, P0Zn10, P30Zn0, P30Zn2.5, P30Zn5, P30Zn10, P60Zn0. P60Zn2.5, P60Zn5, P60Zn10, P90Zn0, P90Zn2.5, P90Zn5 and P90Zn10 were experimented in randomized block design with 3 replications. All the growth and yield parameters increased significantly with increasing levels of phosphorus up to 90 kg ha-1. However, growth and yield parameters of chickpea were increased up to 5 kg Zn ha-1 and further increase in the level of Zn does not show significant influence on growth and yield of chickpea. Interaction effect of P and Zn levels on the grain and straw yield of chickpea was significant during study. Thus, it may be concluded that application of phosphorus and zinc proved more beneficial in improving the productivity of chickpea crop. The result showed that application of P and Zn also improved the growth and yield. Phosphorus requirement of chickpea was found more.
