Effect of boron and farmyard manure application on boron concentration and dry matter yield of paddy

Abstract

A pot experiment was conducted to study the effect of boron applied at four levels (viz., 0, 0.5, 1 and 2 kg B ha-1) and FYM applied at 0 and 5 t ha-1 on boron concentration as well as dry matter yield of paddy (var. CAU-R1) grown in an acid soil. Results revealed that irrespective of different levels of boron and FYM, there was an increasing trend of boron concentration and dry matter yield up to harvest. Significantly higher boron was accumulated in paddy grown in soil added with boron over control at different crop growth stages. Interaction of boron and FYM levels had no significant influence on boron concentration during the whole experiment. Application of boron @ 2 kg ha-1 and 5 tonnes ha-1 FYM in combination enhanced the boron concentration and dry matter yield at the latter growth stages of paddy. This shows more agronomic effectiveness of boron when applied in combination with FYM.
