To Investigate the Rate of Release of Boron from Different Sources and Levels of Boron at Varying Period of Incubation

The time of incubation had the pronounced effect on boron availability. The boron availability of each product increased up to 45th days of incubation period, and then it was decreased. Availability of boron seems to have direct relationship with the quantity of applied boron. Thus, the overall availability of boron increased with the increasing dose of applied boron sources. Among the different sources of boron, the rate of release of available boron was highest in Boric acid followed by Borax and Agricol. The interaction effect of different sources and periods was found significant. The highest availability of boron was registered at 45th days of incubation period with 10 ppm Boric acid treatment.
