Simultaneous Transmission

Aneuploids have been identified among progeny from the homozygous recessive asynaptic soybean (Glycine max (L.) Merr., 2n = 40) mutants T241 and T242. The majority of the progeny (206 of 217) examined were near the tetraploid level and were sterile. The only fertile F1 aneuploid had 36 F2 progeny, which ranged in chromosome number from 41 to 44. Among the F2 progeny, pollen fertility, number of seed per plant, and plant height decreased as chromosome number increased. No morphological differences were observed among the F2 trisomics or between them and fertile diploids. The progeny of 2 of 3 F2 trisomic plants contained plants with 42 chromosomes, suggesting simultaneous transmission of the extra chromosome in both the pollen and the egg.

Herbicide Drift

There have been anecdotal accounts of increased crop sensitivity due to herbicide drift followed by an in-crop herbicide. An experiment was conducted from 2005 to 2007 at Elora, Ridgetown, and Woodstock, Ontario, to determine the effects of simulated mesotrione drift followed by in-crop applications of glyphosate, imazethapyr, bentazon and glyphosate plus chlorimuron on glyphosate-resistant soybean [Glycine max (L.) Merr.] visual injury, plant height, plant density, shoot dry weight, and seed yield. As the rate of simulated mesotrione drift increased, there was an increase in soybean injury and a decrease in shoot dry weight, height, and yield. Simulated mesotrione drift followed by bentazon resulted in synergistic responses in injury shortly after application in some environments. This increase in injury was transient, with no synergistic responses in density, shoot dry weight, and yield. In contrast, antagonistic responses were observed when glyphosate, imazethapyr, or glyphosate plus chlorimuron were applied after simulated mesotrione drift in some environments. Further research is required to develop a better understanding of the interactions of drift followed by the application of an in-crop herbicide.

A pot experiment was conducted under rainfed condition to study the effect of water hyacinth compost on the morpho-physiological parameters of soybean (Glycine max L.) at the Teaching and Research Farm of Faculty of Agriculture and Veterinary Medicine, Imo State University, Owerri. The treatments were control (T1) 100g (T2), 150g (T3) and 200g (T4) of water hyacinth compost and replicated four times. The treatments were arranged in Complete Randomized Design (CRD). The parameters measured were plant height, number of leaves, leaf area (cm2), leaf area index, relative growth rate (RGR), Net assimilation rate (NAR), shoot dry weight(g), yield and yield components (Number of pods, pods weight, 100 seed weight). The results obtained indicated that T3 significantly produced highest plant height (57.6cm) compare to control. While it was observed that T4 (200g) significantly produced the highest number of leaves (233.25), leaf area (631.80cm2), shoot dry weight (15.445g), number of pods (129.75), pod weights (25.38g) seed weight (7.23g) and yield (0.72kg/ha) relative to control and other treatment levels. Root parameters were also significantly improved by the rates of water hyacinth application compared to control. It will be worthy to note that there was no nodulation perhaps that was why the yield was poor. The results showed that soybean growth can effectively be improved with incorporation of water hyacinth into soil.

Giving Superfarm Rhizobium and N fertilizer on the Growth and Production of Soybean (Glycine max L. Merill.). The aim of research to determine the effect of Superfarm Rhizobium and N fertilizer on the growth and yield of soybean (Glycine max (L. Merill). The study was conducted over four months, from March to July 2015. The study in Dusun Desa Sumber Jaya Manunggal Jaya Rt. 09 District of Tenggarong Seberang Regency. this study used a draft split plot with factorial 3 x 4 consisting of three replications. the first factor is Superfarm Rhizobium which comprise three levels: ie s0 (without treatment), s1 (2 g / plant), s2 (4 g / plant). The second factor is the dose of N fertilizer consists of four levels ie N0 (without fertilizer) n1 (2.5G / plant) n2 (5g / plant) and n3 (7,5g / plant) . the results showed that treatment of Rhizobium Superfarm Award (S) had no significant effect on all parameters. While the provision of fertilizer N (N) significantly affected plant height parameter parameter 2, 4 and 6 weeks after planting. and at a dose of 7.5 g significantly the parameters of crop seed weight, seed weight per plot, the production results (Ton ha-1). The highest production was achieved by treatment s0n3 483.33 g / plot, equivalent to 2.69 Toh ha-1.

The effect of seeding rate (seeds per hectare) and row width (distance between rows) was examined for various adapted soybean (Glycine max (L.) Merr.) cultivars in southwestern Ontario. Maple Arrow, Harosoy 63 and Harcor cultivars were grown in 18-, 35-, 53-, 71-, and 89-cm row widths seeded at 198 000, 395 000, and 593 000 seeds/ha during 1978 and 1979. The greatest yields were associated with the two narrowest row widths and the two highest seeding rates. Plant height, lodging, and bottom pod height varied mainly with seeding rate and cultivar. In another 2-yr study (1980 and 1981) Maple Arrow, Evans, S1346, Hodgson, A2575, and Harcor were grown at four row widths (18, 35, 53, and 71 cm) and two seeding rates (395 000 and 593 000 seeds/ha). A significant cultivar × row width interaction for yield occurred with Maple Arrow and Harcor showing the greatest yield response. Although a small seeding rate × cultivar interaction occurred, generally, seeding rates between 395 000 and 593 000 seeds/ha were adequate for all cultivars and all row widths.Key words: Glycine max (L.)

This study aims to determine the growth of various soybean varieties on Ultisol soil, especially on Ultisol soils in Kutacane. The study was conducted in Gulo Village, Darul Hasanah District, Southeast Aceh Regency, Aceh Province with hilly topography, from May to September 2019 at an altitude of 3200 asl. The study used a Non Factorial Randomized Block Design (RBD), with 4 treatment varieties (V) repeated in 4 replications with 63 plants per plot with 7 samples per plot. The plot size  is 3 m x 2 m with 30 x 20 cm spacing. The total number of plants was 1008, while the total number of sample plants was 112 plants. There are 4 soybean varieties: (V1) Anjasmoro, (V2) Dena1, (V3) Deja 1, and  (V4) Detap 1. The parameters observed in this study during vegetative period include plant height at 1, 2, 3, 4, 5, and 6 week after planting. The plant height were measured from the base of the stem to the highest leaf. The result is that each variety has a different response to the environment so that the growth, flowering period, and harvest period are also different on Ultisol soil especially in District of Southeast Aceh.
