An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G- 2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (4) 50 cm were used in the experiment in a split-plot design with row spacing in the main plot and cultivars in the sub-plot. Seeds were sown on 26 July 2005 at specified rows maintaining 5 cm plant to plant distance. The highest seed yield was obtained from 20 cm spacing and yield decreased with increased spacing irrespective of cultivars. Among cultivars the highest yield was given by cultivar BS-5 which was followed by PB-1. It was concluded that the soybean cultivars BS-5 and PB-1 could be selected for sowing in Kharif-II season and should be planted at 20 cm apart rows for achieving higher yield.

Nitrogen was a key component for increasing yield and quality of vegetables like shallots. The growth and development of plants were influenced by nitrogen form. Common plants preferred nitrate for growth, but the enormity preference varies within plant species and other environmental factors. The purpose of this experiment was to study the effect of ammonium:nitrate ratio in sandy soil to growth and yield of shallot (Allium cepa L. Aggregatum group). The experiment had been conducted in August-October 2015 in the sandy land on Samas Beach, Bantul, Yogyakarta, Indonesia. The research was arranged in a Split-Plot design. The main plot was the source of nitrogen (NH4+; NO3-; NH4+: NO3- 1:1; NH4+: NO3- 1:2; and NH4+: NO3- 2:1) and the subplot was cultivars (Crok Kuning, Tiron, and Bima Brebes). Each subplot covered an area of 2.5 m² (2.5 m x 1 m) with three blocks as replications. Shallot bulbs were planted in sixth-row, spacing 20 cm between rows and 15 cm within rows. The dose was applied according to the recommendation of BPTP (urea 200 kg ha-1, ZA 250 kg ha-1, SP-36 150 kg ha-1, and KCl 150 kg ha-1) 144.5 kg N ha-1. Ammonium:nitrate ratio influenced shallot growth in sandy soil through number of leaves at maximum vegetative phase and its leaf area. The NH4+: NO3- 1:2 ratio gave the best result in dry weight of leaves following bulb dry weight than other ratio. Nevertheless, ammonium:nitrate ratio had no significant influence on bulb dry weight (ton ha-1).

Elevated ozone and rising temperature are both factors in climate change, but they are difficult to study in combination due to exposure system requirements. We developed and deployed an air exclusion exposure system to treat soybean (Glycine max (L.) Merr.) cultivar “Jake” with season-long combinations of sub-ambient ozone (18 ppb, 12 h mean), elevated ozone (66 ppb, 12 h mean), and elevated temperature (+3.5 °C daytime, +2.4 °C nighttime) in irrigated field plots. Warming caused a shift in biomass partitioning from reproductive tissues into stems and petioles at mid-season that resulted in a significant 25% reduction in final seed yield and a significant reduction in harvest index. The elevated ozone treatment delayed mid-season biomass production, and final seed yield was reduced by a non-significant 2%. However, there were significant underlying effects of elevated ozone on seed production. The non-significant impact of ozone on seed yield of cultivar “Jake” resulted from significant increases in pod number (+16%) and seed number (+18%) that were offset by a significant reduction in seed size (−16%). No evidence of significant warming–ozone interactions was found in biomass or seed yield responses. In general, significant impacts of the individual warming or ozone treatments were found to be additive.

Two short-season soybean (Glycine max (L.) Merrill) cultivars, Altona and Clay, were tested in narrow rows (10, 15, 20 and 30 cm), and at four rectangularities (1:1, 1:2, 1:3, and 1:4) giving plant densities that ranged from 11 000 to 4 000 000 plants per hectare. Significant yield differences were demonstrated by narrowing row width, but not by changing rectangularity. In a second experiment, the same cultivars were grown in rows 15, 30, 45, and 60 cm apart, but with the density held constant at 670 000 plants/ha. This resulted in respective rectangularities of 1:1.5, 1:6, 1:13.6 and 1:24. Neither seed yield nor its components showed any significant response to row spacing in the second experiment.

Silica is one of beneficial nutrient in plants. Silica functions to strengthen epidermal wall and vascular tissues so that it can affect the stems that are getting bigger and stronger. The present study was conducted to determine the effects of silica fertilizers on growth and yield of chrysanthemum plants in Sheena and Snow White varieties that have different anatomies. The present study used Split Plot Design. The main plot was the concentration of silica with 4 levels, i.e. 0 mg/l/m2, 31.1 mg/l/m2, 62.2 mg/l/m2, and 93.3 mg/l/m2. The subplots were two varieties, Sheena and Snow White. The present study revealed that Si fertilizers with 62.2 mg/L concentration could accelerate harvest age and the stem hardness in Snow White aged 45 days. The Snow White which has bark stem anatomy was more responsive to silica fertilizers than the Sheena with the woody stem anatomy. This research provides benefits for researchers, farmers and policy stakeholders to increased yield and quality for local and international market competition.

The availability of qualified and sustainable seeds is one of the determinants of the success of shallot farming. One of the constraints factor in the supply of shallot seeds is the short storage period that is about 2-3 months. This study aims to determine the effect of varieties and seed storage period on growth and yield shallots. This research was conducted at Indonesian Vegetables Research Institute, Lembang, West Java, Indonesia. The study was designed using split plot design with four replications. The main plot was seed storage period for four months, five months and six months after harvest and the subplot was varieties, consisting of seven varieties that have been released, namely Bima Brebes, Katumi, Kuning, Pikatan, Trisula, Pancasona and Mentes. The results showed that the yield of wet bulbs per hectare of five-months-storage period bulb seeds was significantly higher than six months storage period for the varieties of Bima Brebes, Katumi, Kuning, Pikatan, Pancasona and Mentes. Five-months-storage period of shallot bulb seeds can still be used as a source of seeds for the varieties of Bima Brebes, Katumi, Kuning, Pikatan, Pancasona and Mentes.

Soybean (Glycine max L. Merrill) is one of the most important crops worldwide. In several European countries such as Germany, soybean cultivation is not traditional and as such remains to be optimized. One option to increase soybean production is to adapt and improve the seeding system. To investigate the effects of different seeding systems on seed yield, seed protein, and oil content, plant characteristics were assessed using a two-factorial (two seeding systems and four cultivars) field trial over two years (2017–2018) at two locations in southeast Germany. The seeding systems were drill (row spacing 14 cm) and precision seeding (row spacing 28 cm), and the cultivars were Viola 000, Lissabon 000, ES Mentor 00, and Orion 00. Depending on the seeding system, a seed yield of 3.8 t ha−1 dry matter (DM), 40.9% protein content (DM), and 18.8% oil content (DM) was achieved by drilling, and 3.6 t ha−1 yield (DM), 40.1% protein content (DM), and 19.1% oil content (DM) with precision seeding (average across four cultivars, two locations, and two years). No significant effects of the seeding system on all seed and plant characteristics were observed. As drilling and precision seeding did not affect the seed yield, seed protein, oil contents, and plant characteristics of soybean in this study, farmers are able to choose the seeding system which fits best into their farms and is economically most viable.
