Agricultural Performance

The aim of this study was to determine the effects of pre-sowing seed treatment with cold plasma (CP) and an electromagnetic field (EMF) on the agricultural performance of two cultivars of common buckwheat (Fagopyrum esculentum Moench)—‘VB Vokiai’ and ‘VB Nojai’. For this, the effects of CP and EMF on seed germination, plant growth in the field, photosynthetic efficiency, biomass production, seed yield, and the amount of secondary metabolites and minerals in the harvested seeds were estimated. Although the percentage of seedlings that emerged under field conditions decreased by 11–20%, seed treatments strongly improved buckwheat growth and yield. Irrespective of differences in the dynamics of changes in the growth and photosynthetic activity between the two cultivars, the weight of seeds collected per plant for both cultivars was significantly higher (up to 70–97%) compared to the control. The biochemical composition of the harvested seeds (Fe, Zn, quercetin content) was also altered by seed treatments. Thus, pre-sowing treatment of buckwheat seeds with CP and EMF substantially stimulated plant growth in the field, increased biomass production, seed yield and nutritional quality. The results obtained strongly support the idea that plant seed treatment with physical stressors has great potential for use in agriculture.

Clover Seed

This study aimed to estimate the effects of cold plasma (CP) and electromagnetic field (EMF) treatment of red clover (Trifolium pratense) seeds with different coat colors on germination kinetics, the content of seed phytohormones, and the growth of seedlings. Seeds of red clover cultivar ‘Arimaiciai’ were treated with radio-frequency EMF or capacitively coupled low-pressure CP for different durations. There were no differences in germination kinetics between yellow, brown, and dark purple seeds in control, but the germination rate of seeds treated with CP and EMF depended on seed color: The germination of yellow seeds was stimulated stronger compared to dark purple and brown seeds, and EMF did not stimulate germination in brown seeds. The content of phytohormones in control seeds and the shift in their amount induced by seed treatments were also strongly dependent on seed color. No relationship was found between the effect on germination kinetics and changes in phytohormone levels. In the control, seedlings growing from the yellow seeds were heavier, and the number of root nodules was 12.5 times larger compared to seedlings of dark purple seeds. Seed treatments with CP and EMF significantly increased the number of root nodules, and this effect was stronger in seedlings from dark purple seeds compared to those from yellow seeds.

The effect of seed biopriming with different bioagents including plant growth promoting rhizobacteria (PGPR-1), rhizobial biofertilizer (Rhizobium strain B1) and biological control agent (Trichoderma viride) was observed on plant growth, seed yield and incidence of diseases in French bean cv. Contender conducting a field experiment during kharif season in the year 2017 and 2018. Under field conditions in both the years, field emergence (95.18 %), plant height at 30 days after sowing (34.09 cm), plant height at final harvest (56.99 cm), days to pod harvest (52.33), harvest duration (18.67), pod length at final harvest (16.83 cm), number of pods per plant (20.17), dry pod weight (2.72 g), pod yield per plant (38.64 g), number of seeds per pod (7.17), seed yield per plant (20.76 g), seed yield per plot (875.33 g), seed yield per hectare (23.34 q), 100 seed weight (34.19 g), quality of harvested seeds were recorded significantly higher after seed biopriming with PGPR-1+ Rhizobium strain B1 (T4) as compared to carbendazim seed treatment and untreated control. This treatment combination also reduced the incidence of major diseases like, Rhizoctonia root rot and Angular leaf spot significantly as compared to carbendazim seed treatments and untreated control. It can be concluded from the present investigation that seed biopriming of French bean cv. Contender with PGPR-1+Rhizobium strain B1 @ 109cfu/ml for 8 hours was an effective treatment which significantly improved plant growth, pod yield, seed yield, seed quality and seed vigour and reduced disease incidence as compared to seed treatment with carbendazim @ 0.2% as well as untreated control under field conditions.

Background: Salicylic acid (SA) is an endogenous plant growth regulator plays a vital role in plant growth, ion uptake, transport, interaction with other organisms and in the responses to environmental stress. The aim of the study was to find the effect of salicylic acid on chlorophyll content, superoxide dismutase and malondialdehyde level of leaves and seed yield parameters of soybean.Methods: Field trials were conducted during kharif 2018 and 2019 at ICAR-Indian Institute of Soybean Research, Indore farm (22.78oN, 75.88oE), India. Salicylic acid applied as foliar spray with (50,100 and 200 ppm) concentrations at vegetative stage (22-25 days after sowing) and at pod filling stage (57-60 days after sowing). Chlorophyll content, lipid peroxidation activity and superoxide dismutase enzyme, plant height, number of pod per plant, seed yield and seed index were determined.Result: Chlorophyll content, antioxidant enzyme were enhanced and the level of lipid peroxidation of leaves was reduced as compared to untreated plant when salicylic acid applied at critical stage of crop growth. Significant increase in soybean seed yield was observed both with concentration of 100 and 200 ppm salicylic acid. Foliar spray with salicylic acid @ 100 ppm at vegetative and at pod filling stage was very effective for better seed production programme to improve quantity as well as quality of soybean seeds.

In this study, the effects of seed treatments with different stressors, such as cold plasma (CP), a vacuum and an electromagnetic field (EMF), on the in vitro germination of industrial hemp cv. Futura 75 were compared with the effects on germination in the field, plant growth, and the amount of major cannabinoids in the leaves and inflorescences of female plants. CP and EMF (but not vacuum) treatments improved in vitro seed germination, but had no impact on germination in the field. EMF treatment increased the weight of the above-ground part of male and female plants grown for 4 months by 65–70% and the number of female inflorescences by 70%. CP stimulated the growth of male plants (weight increased 1.4 times) but reduced the growth of female plants. Vacuum treatment did not induce changes in the growth of female and male plants. Vacuum and EMF treatments did not change the amount of cannabidiolic acid (CBDA), but CP decreased the CBDA content in hemp leaves by 41%. Vacuum treatment increased the amount of CBDA in female plant inflorescences by 26%. Thus, hemp seed treatment with EMF has a potential application for increasing the biomass of female plants. CP treatment can be used to increase male plant production while vacuum treatment can stimulate CBD production.

The viability of commercial Rhizobium strains (SB-14 and SB-12) were inoculated and fungicides (Mancozeb and Ridomil) were used as seed dressed on soybean seed to investigate their effect on nodulation, plant growth and seed yield of soybean. Application of Rhizobial inoculants alone gave the highest nodulation and shoot dry weight performance as well as seed yield of soybean on both sites. SB-12 inoculant had significantly shown to be more effective than SB-14 inoculant in increasing nodulation and thus produced higher plant growth and seed yield. Rhizobial survival on the seeds was severely affected by both fungicides, resulting in decreased nodulation, plant growth and seed yield for both inoculants. However, Ridomil fungicide gave the lowest nodulation and seed yield when applied with either SB-12 or SB-14 Rhizobial strains. The strains differed in their sensitivity to Mancozeb fungicide that with strain SB-12 showed a slight effect or no effect on survival of rhizobium, nodulation and yield of soybean. Seed-dressing of mancozeb and ridomil resulted in reduction of seed yield by 882.8 kg ha-1 and 1154.7 kg ha-1, respectively with SB-12 strain. The present results indicate that inoculated Rhizobium inoculants differ in their capacity to develop resistance to the two dressed fungicides. Seed treatment with Mancozeb in combination with SB-12 strain slightly affected the survival of the inoculated strain. Consequently, mancozeb fungicide may be compatable with survival of the inoculated SB-12 Rhizobia. The results also indicate that the suppressive effects of seed-applied fungicides on Rhizobium strains survival and nodulation development depend on specific strain and fungicide. Soybean seeds inoculated with SB-12 may not need management with fungicides or lower concentration of Mancozeb that could be compatible with SB-12 to suppress soil-borne pathogens for both Assosa and Begi sites, western Ethiopia.
