Agric. Nat. Resour. 79-89. Crop production practices affect weed communities in agricultural systems. Field experiments were conducted to determine the effects of organic and inorganic fertilization on weed flora and seed yield in black mustard [Brassica nigra (L.) Koch] crops. The experiments, conducted at two sites (Athens and Agrinio, Greece) during 2019, were laid out in a randomized complete block design with three replicates and three fertilization treatments (untreated, compost fertilizer and inorganic fertilizer). The results of the present study indicated that the total weed density and biomass in the black mustard crops were significantly influenced by fertilization. The highest leaf area index (4.76-4.84 m 2 m-2) and canopy interception of incident photosynthetically active radiation (PAR) (93.56-94.98%) were observed under inorganic fertilization at 90 days after sowing. At both experimental sites, the total weed density and biomass were significantly higher under inorganic fertilizer treatment at 45 DAS. The highest densities of the weed species Sinapis arvensis, Chenopodium album and Malva sylvestris were found in the plots treated with inorganic fertilizer. The seed yield was also affected by fertilization, with the highest values (1352-1456 kg ha-1) observed in the plots treated with inorganic fertilizer. In conclusion, the different fertilization practices affected both the weed density and weed biomass; in particular, inorganic fertilization led to the development of he highest weed density. Furthermore, the highest seed yields were recorded under inorganic fertilization in both the experimental areas.

“…Increased biomass output, the growth of more secondary branches, and enhanced plant height number of pods are all linked to the rise in grain weight, which is principally caused by the soil's higher nitrogen content. The research conducted Daniya [26] phosphorus fertilizers are essential for increasing soil fertility and encouraging both plant height and overall plant growth.…”

Sesame, an important oilseed crop and valuable source of protein, plays a central role in global agriculture. This study, conducted during the 2021-2022 Kharif season at Karor Adaptive Research Farm (ARF), Layyah, Pakistan, aimed to optimize the use of NPK (nitrogen, phosphorus and potassium) fertilizers to increase sesame yield under dry conditions. Our research aimed to determine the most effective application rates of NPK fertilizer (34:24:12) kg/acre for sesame variety TH-6 in the region, consistent with the objectives of maximizing sesame yield and biomass accumulation. The experimental design RCBD included multiple treatments, with meticulous attention to plot sizes, replicates, and robust data collection and analysis methods. These measures ensure the reliability of our results and their potential applicability to similar agroclimatic conditions. The use of NPK fertilizer at the rate of (113:113:60) kg ha-1 in ARF gave promising results. A maximum grain yield of 765.3 kg ha-1 was observed in 2021, exceeding the yield of 738.6 kg ha-1 in 2022. Similarly, the use of NPK (113:113:60) kg ha-1 in a farmer's field resulted in a maximum grain yield of 828.6 kg ha-1 in 2021, as opposed to 702.6 kg ha-1 in 2022. These results highlight the potential of NPK fertilizer application combined with optimal field practices to increase sesame yield and its components under the challenging agro-climatic conditions of Karor, Layyah. The discussion interprets the results and emphasizes the importance of NPK fertilizers for sesame cultivation. Although our primary focus is not on climate discussions, the consistent methodology in both years, from sowing to harvesting, revealed significant differences in yield and growth parameters, leading to climate change being considered as a potential contributing factor. This study shows that the application of NPK fertilizer at the rate of (113:113:60) kg ha-1 can significantly increase sesame yield under adverse conditions.

Sesame is an oil seed crop with great economic value. However, the production of this crop has been limited by weed competition, which prompted a field experiment during the 2021 cropping season in two locations: Teaching and Research Farm, Kwara State University, Malete, and National Centre for Agricultural Mechanization (NCAM), Idofian, Ilorin, Kwara, Nigeria. The aim was to determine the treatment combinations of sowing methods and herbicide mixtures for the effective management of weeds and for increasing sesame productivity in the southern Guinea savanna of Nigeria. The experiment consisted of twenty treatments comprising two sowing methods (dibbling and drilling) and ten weed control methods. Results showed that all the weed control methods reduced weed dry matter (67.15–186.20 and 42.00–92.45 g/m2) than the weedy check (291.55 and 155.55 g/m2) at Malete and NCAM, respectively. They also reduced the weed density (48.40–68.45 and 34.00–50.00/m2) compared to the weedy check (103.60 and 73.15 g/m2) at Malete and NCAM, respectively, from 6 to 12 weeks after planting (WAP). Dibbling (85.15 and 48.81 m2) proved superior to the drilling method (172.42 and 51.58/m2) for the management of weeds from 6–12 WAP and for promoting higher crop yield (dibbling: 78.90 and 422.70 kg/ha; drilling: 37.50 and 326.80 kg/ha) in Malete and NCAM, respectively. The treatment combinations with the highest gross margin were hoeing twice at 3 and 6 WAP × dibbling ($ -191.15 and $ 318.57), pendimethalin (P) + diuron (D) at 0.5 + 0.5 kg a.i./ha ($ -199.88 and $ 182.43), 2.0 + 1.5 × dibbling ($ -273.59 and $ 156.65) and butachlor (B) + diuron (D) at 1.5 + 1.0 kg a.i./ha × drilling ($ -269.59 and $ 177.38) at Malete and NCAM, respectively. Therefore, it is recommended that the dibbling sowing method at a spacing of 30 cm × 30 cm and thinned to 3 plants/stand integrated with herbicide mixtures of pendimethalin at 0.5 + 0.5 kg a.i./ha is recommended as an alternative to hoe weeding for effective weed control, higher yield of sesame, and economic returns.
