| Growth of corn responded markedly to application of phosphorus from both phosphate rock and triple super phosphate. It was found that corn with application of 6 and 30 gm P/pot of PR had average plant height (at 30 and 50 days after planting) of 77 percent and 82 percent, compared to the growth of corn with 6 gm P/pot of TSP. And increasing the rate of phosphorus from PR to 60 gm P/pot resulted of 92 percent in growth, compared to that from application of triple super phosphate. No application of phosphorus resulted in only 69 percent of the growth of corn, compared to that from application of triple super phosphate. Similarly, the application of phosphorus from phosphate rock (PR) at the rates of 0, 6, 30 and 60 gm P/pot resulted 29 percent, 38 percent,... |
