Effect of Boron and Farmyard Manure on Different Types of Soil Boron Forms

Abstract

An experiment was conducted at Agriculture University Chatha in order to evaluate the effect of Boron and FYM application on different types of soil Boron. Composite surface soil samples (0-15 cm) from different locations were collected and analyzed for water soluble boron (WSB), Hot water soluble boron (HWS-B), Calcium chloride soluble boron (CCSB) and Acid soluble boron (ASB) using standard procedures. It was found that T₇ (15 kg ha^-1 borax along with 100% FYM) was highly effective among all thereby reflecting 31.5% higherwater soluble boron availability than control and 54.2% increase in Acid soluble boron. In addition to this, higher values of Hot water soluble boron and Calcium chloride soluble boron were noticed in the same treatment. Therefore, in future farmers can be advised to use the Borax @ 15 kg ha^-1 along with 100% of FYM as a promising treatment to increase boron availability compared to others
