The impact of boron seed priming on seedling establishment, growth, and grain biofortification of mungbean (Vigna radiata L.) in yermosols

Abstract

Boron-deficiency in Yermosols is among the major constraints to mungbean productivity and grain biofortification in Pakistan. However, agronomic strategies such as boron (B) seed priming have potential to improve mungbean yield and grain biofortification. Moreover, deficiency to toxicity range for B is very narrow; therefore, it is pre-requisite to optimize its dose before field evaluation. A wire house experiment was planned out to reconnoiter the impact of seed priming with B on growth and quality of two cultivars of mungbean, i.e., ‘NM-2011’ and ‘NM-2016’. Four different B levels were used as seed priming, i.e., 0.01%, 0.05%, 0.1% and 1.0% B, (borax Na2B4O7.10H2O, 11.5% B) were tested, whereas hydropriming was regarded as control. Seed priming with 0.01% B significantly (p≤0.05) lowered time taken to start germination and time to reach 50% emergence, whereas improved mean emergence time, emergence index, final emergence percentage, number of leaves, dry and fresh weight of root, shoot, and total weight, root length, plant height, chlorophyll contents, number of pods and 100-grain weight, seeds per plant, grain yield per plant, B concentrations in stem and grain, grain protein, carbohydrate and fiber in both cultivars. Boron seed priming proved beneficial under a specific range; however, deficiency (hydropriming) and excess (above 0.01% B) of B were detrimental for mungbean growth and productivity. The cultivar ‘NM-2016’ had significantly (p≤0.05) higher yield due to prominent increase in yield related traits with 0.01% B priming as compared to ‘NM-2011’. In conclusion, B seed priming (0.01% B) seemed a feasible choice for improving mungbean growth, yield related traits and grain-B concentration of mungbean on Yermosols.

Impact of Pre-Sowing Seed Treatments on Sweet Corn Landraces under Moringa leaf extract

“…Among the different landraces of sweet corn, late emergence (8.6 days) was noted in the Kunarh landrace, which followed Mingora (8.4 days), while early emergence (7.8 days) was recorded in the Kashmir landrace of sweet corn. The results of the current investigation are in accordance with the reports of Rehman et al, (2022) who reported that primed seed decreased the emergence time and improved germination compared to dry seed or control. The results also follow those of Irshad et al (2022) & Mashamaite et al (2022, who established that Moringa leaf extract encouraged earlier emergence and seedling growth.…”

Thermochemical processing of boron-impregnated cellulose insulation waste for upcycling to slow-release boron fertilizers

“…The response pattern showed that borax application at a dose of 7.2 mg B kg -1 increased the vegetated area and DMY in comparison with the control treatment. This positive effect on seed emergence and seedling development was also shown by Rehman et al (2022). However, with borax application above 7.2 mg B kg -1 , increasing doses decreased the vegetated area and DMY as a result of B toxicity, resulting in the complete absence of germination at a dose of 115.2 mg B kg -1 .…”

Nanopriming and AI for Sustainable Agriculture: Boosting Seed Germination and Seedling Growth with Engineered Nanomaterials, and Smart Monitoring through Deep Learning

“…Priming solutions commonly used are hydropriming (using water), 23 osmopriming (involving polyethylene glycol and inorganic salts), 24 hormonal priming, 25 and nutrient priming. 26 However, the effectiveness of these priming solutions can vary depending on the properties of the solution and the specific requirements of different crop species. 27 Integrating ENMs into seed priming processes offers a novel approach to enhance crop productivity and quality potential, providing valuable solutions for sustainable agriculture.…”
