Foliar application of boron positively affects the growth, yield, and oil content of sesame (Sesamum indicum L.)

Abstract

The objective of this study was to determine the optimal concentration of boron (B) to obtain the highest growth, yield, and oil content of black sesame. A field experiment was conducted in a completely randomized block design with five treatments and five replications. Treatments included foliar application of B at five rates: control, 50, 100, 150, and 200 mg L−1 at 25 and 35 days after sowing. Results showed that spraying B on leaves increased sesame growth in terms of plant height, number of leaves, and chlorophyll content. Moreover, spraying B increased yield components including the number of pods; the highest pods per plant was 46.2 in the B application treatment with 150 mg L−1 compared to the control with 27.2 pods per plant. The grain yield of the B spray treatment produced 1.10–1.32 t ha−1, with the highest yield at the dose of 150 mg L−1 and the lowest yield at no B spray treatment. Spraying B on leaves at optimal concentration also increased the oil content in seeds up to 5.3% compared to the control treatment. The findings of the study suggest that foliar B application with 150 mg L−1 increases the growth, fruit set, seed yield, and oil content in sesame.

Effects of Nitrogen Fertilization and Nitrogen Fixing Endophytic Bacteria Supplementation on Soil Fertility, N Uptake, Growth, and Yield of Sesame (Sesamum indicum L.) Cultivated on Alluvial Soil in Dykes

“…After 7 days, two sesame plants were put into each pot. Chemical fertilizers formula: the NPK fertilizers recommended for 1 hectare were 90 kg N-60 kg P 2 O 5 -60 kg K 2 O. is formula was followed by Khuong et al [13]. e reduction by 25% for each level is based on their uptake ability and also the effects of N fertilizer on growth and yield of sesame.…”

The Effectiveness of Dolomite Phosphate Rock on Growth and Yield of Black Sesame (Sesamum indicum L.) in Paddy Field

“…The chlorophyll content in a leaf (µg Chl cm -1 ) was measured 45 days after sowing, according to the N,Ndimethylformamide method (Moran,1982). The number of pods per plant, pod weight, the number of seeds per pod, the weight of 1.000 seeds and yield were determined according to Khuong et al (2022). Nitrate, phosphate and potassium contents in the stem and leaves were measured 50 days after sowing and in seeds, according to Temminghoff and Houba (2004).…”

“…Therefore, sesame is one of the sources of nutrients that improve human health. In the Mekong Delta, Vietnam, sesame is an attractive crop to grow in rotation with rice due to its relatively low nutrient requirements, resilience to low soil moisture (as it is not dependent on post germination irrigation) and heat tolerance (Khuong et al, 2022). However, the sesame area in Vietnam is about 34,683 hectares with an output of 28,774.67 tons and our country's sesame yield is still relatively low (0.83 tons/ha) (FAO, 2023) because of poor planting and acidic soil caused by the extensive use of chemical fertilizers (Ning et al, 2017;Bhatt et al, 2019), which causes the sesame plant roots to grow poorly developed.…”

Improvement of Nutrient Uptake, Yield of Black Sesame (Sesamum indicum L.), and Alluvial Soil Fertility in Dyke by Spent Rice Straw from Mushroom Cultivation as Biofertilizer Containing Potent Strains of Rhodopseudomonas palustris

“…The world's sesame seed consumption was 6,559.0 million USD in 2018, and it will be 7,244.9 million USD by 2024 [ 5 ]. In Vietnam, black sesame is grown popularly in the Mekong Delta [ 6 ], with an area of 29,059 ha and a mean domestic yield of 0.7313 t·ha −1 in 2018 [ 7 ].…”
