Effect of Agronomic Biofortification of Sulphur and Boron on the Growth and Yield of Mustard (Brassica campestris L.) Crop

Abstract

Background and Objective: Sulphur and boron are found as most critical nutrient elements for the better growth and yield of mustard crop however no such concrete information for their uses in field production of this crop is yet to be reported. Therefore, an experiment was conducted to investigate the effect of agronomic biofortification of sulphur and boron nutrients on the growth and yield of mustard crop.
 Study Design: The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates.
 Place of Study: The experiment was carried out in the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh.
 Methodology: Three doses of sulphur (S) viz. 0, 20 and 40 kg ha-1 and three doses of boron (B) viz. 0, 0.5 and 1.0 kg ha-1 and their possible combinations were used as basal doses. Field data were collected from periodic destructive samplings on the plant height, number of leaves and branches per plant, total dry matter accumulation and finally yield components and yield.
 Results: Sulphur and boron fertilizations significantly influence the plant height, production of branches and leaves per plant, dry matter accumulation and yield attributes and yield of mustard crop. The mustard crop fertilized with 40 kg S ha-1 in combination with 1 B kg ha-1 produced taller plant, higher number of branches and leaves in each plant and higher amount of dry matter per plant while these plant traits were found as minimum when the growing the mustard crops in control plots i.e. the plants received neither sulphur nor boron. Application of sulphur @ 40 kg ha-1 along with boron @ 1 kg ha-1 produced the highest seed yield (2.73 t ha-1) whereas the lowest seed yield (1.08 t ha-1) was found where no sulphur and boron were applied.
 Conclusion: The result conclude that combine application of sulphur and boron @ 40 and 1 kg per hectare, respectively was found to be most effective dose in enhancing growth and yield of mustard crop.

Genotypic Variations of Morpho-physiological Parameters of Rapeseed (Brassica rapa var. Toria) under Rainfed Condition of Assam

“…On the other hand, lowest yield was found in the genotype TKM-20-2 with the value of 4.23 q ha -1 . Awal et al (2014) reported significant variation in seed yield between the two species Brassica campestris and Brassica napus which is similar with the current study. Al-Juheishy et al (2021) revealed significant varietal differences in two rapeseed varieties in terms of seed yield which in corroboration to the findings of the current experiment.…”

“…The findings were in corroboration with the findings of the current study. Awal and Fardous (2014) reported significant differences in plant height, number of primary branches and green leaves in different species of Brassica campestris. The result of the present study is in corroboration with the above findings.…”

Effect of Sulphur and Boron on Growth Characterstics, Yield Components and Productivity Parameters of Mustard (Brassica juncea L.) under Rainfed Condition of Chitrakoot Region, Madhya Pradesh, India

“…The interaction effect due to sulphur (control, 15 kg ha -1 , 25 kg ha -1 and 35 kg ha -1 ) and boron (control, 1.5 kg B ha -1 and 2.5 kg B ha -1 ) on test weight of mustard seeds was found statistically significant. Comparative findings were detailed by Singh et al [33], Awal et al [34] and Rana et al [32]. ) was observed with the application of 35 kg S ha -1 (S 2 ).…”
