Effect of boron and sulphur on growth, yield and nutrient uptake of mustard (Brassica juncea L.)

Abstract

Field experiment was carried out to evaluate the effect of boron and sulphur on growth and yield attributes of mustard (Brassica juncea L.) during Rabi season of 2017-2018 at experimental farm of Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab. The experiment had nine treatments viz., T1- ­­100% RDF, T2- 100% RDF + 2 kg/ha B, T3- 100% RDF + 3 kg/ha B, T4- 100% RDF + 2 kg/ha B + 15 kg/ha S, T5- 100% RDF + 3 kg/ha B + 15 kg/h S, T6- 100%RDF + 2 kg/ha B + 30 kg/ha S, T7- 100% RDF + 3 kg/ha B + 30 kg/ha S, T8- 100% RDF + 2 kg/ha B + 45 kg/ha S and T9- 100% RDF + 3 kg/ha B + 45 kg/ha S with three replications in randomized block design. The results revealed that the highest plant height, number of primary and secondary branches, dry matter accumulation, number of siliquae/plant, length of siliqua, number of seeds/siliqua, grain yield, stover yield and biological yield were recorded with the application of 100% RDF + 2 kg/ha B + 45 kg/ha S which was significantly at par withT9- 100% RDF + 3 kg/haB + 45 kg/haS, T6- 100% RDF + 2 kg/haB + 30 kg/haS and T7- 100% RDF + 3 kg/haB + 30 kg/haS. It was significantly superior over all treatments. While, harvest index was highest where 100% RDF applied.
