Effect of phosphorus (P) doses on tomato seedlings production in poor nutrients substrates and its importance on fruit yield
MetadataShow full item record
The effect of P on different plants and several growth stages are well known to scientists, but there is little information on the effect of P after transplanting the seedling until harvesting. The current study aimed to evaluate the effect of P on tomato seedling and fruit production of Paronset hybrid. Therefore, six treatments (0, 15, 30, 45, 60 and 75mg L-1P) were evaluated in a randomized complete block design with four replications. Monoammonium phosphate (MAP) was used as P source, in addition to coconut fiber substrate. A linear increase was obtained for leaf area, seedling height, shoot and root fresh matter at 75mg P L-1. However, yield and fruits characteristics were not affected by increasing P doses on seedlings.
