An assessment of the impact of ambient ozone on field-grown crops in New Jersey using the EDU method: Part 2—Soybean (Glycine max (L.) Merr.)

To appreciate the impact of insect pollinators on the pod, seeds, and seed weight yields of Glycine max, the pollinating activities of flowering insects were studied in Yaoundé, during the two mild, rainy seasons in 2016 and 2017 (March-June). Observations were made on 45 to 20400 flowers per treatment. The flowers were subjected to different treatments: Free flowers (Treatment 1), bagged flowers (treatment 2), castrated and free flowers (treatment 3), and castrated and bagged flowers (treatment 4). Some (8695 and 3325) flowers of Glycine max (Fabaceae) were observed in 2016 and 2017, respectively, for the diversity and Frequency of insect visits. For results, 1527 visits of 13 insect species distributed in seven orders were recorded on G. max flowers. The most dominating Hymenoptera observed was Apis mellifera, with 40.20 % of the total insect visits. The highest number of insect pollinators harvested in the flowers of this Fabaceae was between 8h-9h. The studied insects have a positive impact on the yields of this plant. This positive impact of the pollinator insects on the yields was 26.29 %, 16.13 %, 15.02 and 4.45 % in fructification rate, number of seeds pod, the weight of seeds, and percentage of normal seeds respectively. The avoidance of pesticide treatment of plants during flowering could be a good management strategy to improve on plant yield.

<p class="Default">An experiment was conducted to investigate the impact of flatbed (FB), ridges and furrows (RF) and broad bed furrows (BBF) combined with recommended fertilizer dose N30P60K30 kg ha−1 (F1), 75 % NPK (F2), 125 % NPK (F3), 75 % NPK + 25 % N through farm yard manure (FYM)-F4, 75 % NPK + 2 sprays of micro nutrient mixture (Fe, Zn, Cu, Mn, B and Mo) - 0.5 % at 35 and 60 days after sowing (DAS)-F5 and 75 % NPK + 2 sprays of KNO3 - 0.5 % at 35 and 1.0 % at 60 DAS (F6) on the productivity of soybean in a split plot design. BBF stored 14.15 % more soil water and produced 1058.97 kg ha−1 more yield than FB. A significant 3.76 kg ha−1-mm rain water use efficiency was notice in BBF compared to FB. The yield increment recorded under F6 was 15.6 % higher than F1. Grain nitrogen and oil contents were highest in F3. The residual soil fertility was much improve by F3 and F5. Our result demonstrated that the combination of BBF and F6 were the best technique to increase soybean yield in the Vertisol soil.</p>

The Impact

The soybean (Glycine max L.) is a crop with a high demand for nitrogen (N). The root nodules that form in soybeans can fix atmospheric N effectively. To quantify available N in the soil a field experiment was conducted at Regional Sugarcane and Rice Research Station, Rudrur to evaluate the impact of varying sowing methods and seed rates on yield of soybean and available N in soil after harvest of crop. Planting methods and seed rates significantly influenced seed yield and available nitrogen in the soil. Broad Bed Furrow (BBF) method with seed rate 50 kg ha-1 recorded significantly higher number of pods per plant (105) and mean seed yield of 1891 kg ha-1 over flatbed with 50 kg seed rate ha-1 (1757 kg ha-1) respectively. Broad Bed and Furrow method of planting recorded a significantly higher live root nodules and available nitrogen in soil with 50 kg seed rate ha-1. Seed rate of 75 kg/ha recorded highest available N in soil on broad bed and furrow method. Broad Bed Furrow (BBF) method with seed rate 50 kg ha-1 recorded highest net returns (₹ 53,233 ha-1) and highest B:C ratio (2.72) over flat bed of planting.

Growth Of Seedlings

The impact of the merosesquiterpenoids avarol (1), avarone (2), 18-methylaminoavarone (3), melemeleone A (4), isospongiaquinone (5), ilimaquinone (6), and smenoquinone (7), isolated from marine sponges of the Dictyoceratida order, was studied on the root growth of seedlings of buckwheat ( Fagopyrumesculentum Moench), wheat ( Triticumaestivum L.), soy ( Glycine max (L.) Merr.), and barley ( Hordeumvulgare L.). Compounds 2 and 6 were effective for the root growth of wheat seedlings, compound 3 stimulated the root growth of seedlings of buckwheat and soy, compound 4 affected the roots of barley seedlings, and compound 5 stimulated the root growth of seedlings of buckwheat and barley. Compounds 1 and 7 showed no activity on the root growth of the seedlings of any of the studied plants. The stimulatory effect depends on the chemical structure of the compounds and the type of crop plant.

The Impact

Plants growing along roadways are often exposed to vehicle exhaust containing both particulate matter (PM) and various gases that could affect gas exchange and thus plant reproduction. To investigate effects of diesel exhaust exposure on plant ecophysiology, growth, and fecundity, individuals of soybean (Glycine max (L.) Merr.) and chicory (Cichorium intybus L.) were exposed to either exhaust from a diesel generator or ambient air. Exposure occurred daily over a 5-day period (beginning 18 June 2013) using open-top chambers in an agricultural field in southwestern Ohio, United States. Plants were evaluated at 3 times (before, directly after exposure, and following a 5.5-week post-treatment recovery period) for photosynthetic rate (A), stomatal conductance (g), water use efficiency (WUE), stomatal clogging due to PM deposition, and number of nodes. Aboveground biomass, fruit number, mean seed number, and seed mass were measured for soybean after the recovery period. In soybean, A minimally decreased with exposure to diesel exhaust (compared to the control), but an increase in g and a decrease in WUE were detected after the exhaust treatment. Chicory exhibited a relatively low increase in A after the treatment, but there were no clear differences in g or WUE. Growth and fecundity were similar among all soybean plants directly after treatment, but after 5.5 weeks plants exposed to diesel exhaust had increased vegetative biomass while exhibiting no difference in fecundity. These plant species reacted differently to short-term diesel exhaust exposure, suggesting that the impact of diesel exhaust will depend on both the plant species and its physiology.
