“…Sebayang and Rifai [18], on the other hand, found that the dry weed weight in the soybean crop did not differ significantly between conventional tillage, reduced tillage, and no-tillage. Nonetheless, many authors point out that the no-tillage system increases weed infestation of crops [29][30][31][32]. Our experiment also demonstrated a significant increase in the number and weight of weeds under the NT system in comparison with CT.…”

This study evaluated weed infestation and health of the soybean crop grown in crop rotation (CR) and monoculture (CM) under conventional tillage (CT) and no-tillage (NT) conditions. The research proved that growing soybean in monoculture and under no-tillage conditions increases weed infestation and infection of soybean with fungal diseases. In these treatments, increased numbers of most of the dominant species were also found. A significantly higher percentage of monocotyledonous species and a much lower percentage of dicotyledonous ones in total weed dry weight were shown in the CR treatment relative to CM and in the NT system compared to CT. The biodiversity of the weed community was similar in monoculture and crop rotation, and slightly greater in the NT system in comparison with CT conditions. In both tillage systems, Amaranthus retroflexus was the weed species that most infested the soybean crop. In soybean grown after itself, Amaranthus retroflexus was the weed that occurred in the greatest numbers, while, in crop rotation, this was Echinochloa crus-galli. In all years of the study, soybean was infected with Septoria glycines to the highest degree, which was followed by Cercospora sojina, whereas infection with Ascochyta sp. was the lowest. Weather conditions in individual years of the study were proven to affect weed infestation and infection of soybean with fungal diseases. The study results prove that cropping systems and tillage systems significantly affect weed infestation and health of the soybean crop.

“…Cow manure gave the highest results on the number of seeds (85.58±27.40), which was significantly different from the control, and increased the number of seeds by about 29.33% (Table 3). Cow manure was reported to have a significant effect on the total weight of seeds, the weight of 100 seeds, and the productivity of the plants (Sebayang and Fatimah, 2019). This is because cow manure has a high content of nitrogen and phosphorus in the soil (Ghedabna et al, 2022).…”

The low production of domestic soybeans is due to the decreasing amount of productive land, so the cultivation of soybeans can be done by utilizing dry land. One type of dryland soil is grumusol soil, which is a less fertile soil and requires improvement through and applying biochar and organic fertilizers. Biochar is expected to increase water availability, thereby increasing nutrient absorption. The research was conducted by experiment with a randomized completed block design (RCBD) two-factor treatment. The treatments are biochar (without biochar as control, biochar of coconut shell, rice husk, and Strobilanthes cusia waste) and organic fertilizer (without fertilizer as control, chicken, cow, and goat manure). Each combination treatment, as an experiment unit, was replicated three times. The results showed that the types of biochar and organic fertilizer do not affect the growth and yield of soybeans. The application of types of biochar alone does not affect the soybean yield, but the various organic fertilizers alone can increase the yield of soybeans. Cow organic fertilizer was able to increase the total pods (31.68%), the number of seeds per plant (29.33%), and the stuffed pods (24.11%).

“…Weed infestation in a crop field is determined by habitat factors and agronomic practices as well as by cultivar properties [Gawęda et al 2015, Sebayang and Rifai 2018, Sebayang and Fatimah 2019, Chojnacka and Haliniarz 2020, Gawęda et al 2020]. Individual cultivars differ not only in their type of use, earliness group, and sensitivity to diseases, but also in their competitiveness against weeds which results, among others, from different rates of initial growth [Shawon et al 2018, Marín 2021.…”

An experiment in growing soybean was conducted at the Czesławice Experimental Farm, belonging to the University of Life Sciences in Lublin, over the period 2018–2020. Three experimental factors were included in this study: cultivation method (conventional and organic), soybean cultivar (Aldana and Merlin), and row spacing (22.5 cm and 35 cm). The species composition, number, and air-dry weight of weeds were evaluated. The Shannon-Wiener diversity index (H’) and the Simpson dominance index (SI) were also calculated for the weed community in the soybean crop. Compared to conventional farming, organic cultivation significantly increased the number and dry weight of weeds as well as the numbers of the dominant species Echinochloa crus-galli. A significantly higher number and dry weight of weeds were found in the cv. Aldana crop than in the case of Merlin. In comparison with narrow-row cultivation, sowing soybean at the wider row spacing resulted in a greater number of weeds, in particular of the species Echinochloa crus-galli. Interrow width in the soybean crop did not cause differences in weed dry weight. The experimental factors slightly modified the Shannon-Wiener (H’) and Simpson (SI) indices.
