“…This result may also be attributed to the volume of soil accumulated under raised bed that allowed for accessibility to nutrients and other resources needed for better growth and development of pepper in those plots. This is in line with the work of Imoloame (2014); Adigun et al (2018) and Kanton et al (2000) who reported better performance of sorghum in raised then flat bed and highest performance of soya bean complimented with hoe weeding under different weed control methods. This result also reveals the effectiveness of the hoe weeding method to significantly reduce the weed cover thereby minimizing weed competition with the pepper plant thereby leading to proper assimilation of nutrients, and accessibilities of sunlight and moisture for proper growth.…”

Licensed under a Creative Commons Attribution 4.0 International License The type of seed beds and weed control methods play significant role in determining sustainability in vegetable production. Field experiment was conducted during 2015 growing season to determine the effects of three seed bed types such as: raised bed (RB), flat bed (FB), ridged bed (RB) in combination with four weed control methods such as: hoe weeding (T 1), hand weeding (T 2), use of Panicum maximum as live mulch (T 3) and zero weeding (T 4) on the vegetative performance of long cayenne pepper (Capsicum frutesens L.) The experiment was arranged as split plot fitted into Randomized Complete Block Design (RCBD) with three replications. The growth parameters measured were the plant height (cm); number of leaves, numbers of branches, stem girth (cm), leaf area (cm 2), weed density (m-2) and weed biomass (kg/ha). The result revealed that the seed bed types and the weed control methods had significant effect on the parameters measured. However, raised bed and hoe weeding (RBT1) enhanced all the parameters measured more than other treatment combinations by recording the highest mean value in all character and also proved to be more effective in reducing weed biomass than other weed control treatment combinations. It was concluded that sowing on raised bed and using hoe weeding as a means of controlling weeds should be recommended for effective performance of pepper for optimum growth.

“…Figure 1 shows that the weed dry weight increased as nitrogen dose increased. Adigun et al (2018) reported that an increase application of N to 90 kg N ha -1 increased weed density and dry weight. The increased N dose also improved the growth and yield of okra.…”

Abstract. Rahayu M, Yudono P, Indradewa D, Hanudin E. 2019. The diversity and physiological activities of weeds in land cultivated with various corn cultivars and fertilized with various nitrogen doses. Biodiversitas 20: 622-628. Both weeds and corn have nutrient needs. Nitrogen is one of the essential elements required by weeds and corn. Each corn cultivar and weed also has different ability to absorb nitrogen. This study aimed to determine the effect of corn cultivar and nitrogen dose on the diversity and physiological activities of weeds. The research was conducted in Banguntapan, Bantul, Yogyakarta from December 2016 to May 2017. The study used a completely randomized block design with 2 factors with three replications. The first factor was corn cultivar, consisting of four cultivars (Bisi 18, NK 33, DK 95 and Sukmaraga) and the second factor was the nitrogen dose, consisting of three levels (25 kg N ha-1, 150 kg N ha-1 and 275 kg N ha-1). The data were analyzed using 5% variance analysis and continued with Duncan test at 5% level. The results showed that the most commonly found weeds were broadleaves, but the most dominant weed was a grass, namely Dactyloctenium aegyptium, except Sukmaraga with nitrogen doses of 25 kg ha-1 and 150 kg ha-1 in 4 weeks after planting (WAP). In 8 WAP, weeds that grew in land planted with all combinations of cultivars and nitrogen doses were Cyperus rotundus, Dactyloctenium aegyptium, Digitaria ciliaris, Eleusine indica, Eragrostis tenella, Amaranthus spinosus, and Richardia scabra. There were no significant differences on the nitrate reductase activity, chlorophyll content, leaf area index, and dry weight among cultivars. The treatment of 25 kg N ha-1 resulted in the lowest leaf area index and total chlorophyll content, but the highest nitrate reductase activity.

“…Hoe weeding under wet condition often causes weed to re-root and reestablish, necessitating several rounds of weeding to keep the crop weed-free and avert yield losses. This is however, tedious, inefficient, time consuming and associated with high labour demands (Datta et al, 2017;Adigun et al, 2018). In addition, labour for manual weeding is scarce and often too expensive for the average farmer to afford (Adigun et al, 2017).…”

“…Alternatively, the use of herbicides is fast and quite effective in suppressing weeds if used at the proper rate and time (Chauhan et al, 2012). Controlling weeds using herbicides reduces drudgery, protect crops from early weed competition and may minimize labour cost (Adigun et al, 2018). However, a single herbicide application may not control the entire weed spectrum with diverse physiology, morphology and time of emergence (Chauhan et al, 2012;Bhagirath et al, 2013).…”

“…Herbicides efficacy is further limited under conditions of high rainfall and prolonged weed germination period (Daramola et al, 2019). Moreover, indiscriminate use of herbicide can result in unintended adverse consequences such as toxicity to off-site or non-target flora and fauna, declining species diversity and herbicide resistance (Chauhan et al, 2012;Adigun et al, 2018). Hence, the need to combine two or more weed management components for broad spectrum weed control.…”

Weed management is an important and expensive step in groundnut production. Field experiments were conducted in the early and late wet seasons of 2017 to evaluate the effectiveness and profitability of weed management using hoe weeding, herbicides or their combination in groundnut production. Butachlor and propaben at 2.0 kg a.i (active ingredient) ha-1 each followed by (fb) supplementary hoe-weeding (shw) at 6 weeks after sowing (WAS) significantly reduced weed cover and biomass with subsequent increase in groundnut pod yield similar to hoe-weeding treatments and better than either herbicide applied alone. The highest groundnut pod yield (1485.7 kg ha-1) and revenue ($1639.2) in the early season was obtained with three hoe weeding passes. However, in the late season, the highest groundnut pod yield (1146.3 kg ha-1) was obtained with propaben plus hoe-weeding and the highest revenue ($1264.8) obtained with butachlor plus hoe-weeding. Although three hoe-weedings gave the highest revenue in the early season, the gross margin and cost-benefit ratio obtained with hoe weeding treatments was lower than those of herbicides fb shw. This study showed that integrated weed management with butachlor or propaben and fb shw will improve weed control, productivity and profitability of groundnut production. Multiple hoe weeding, however, did not guarantee the highest profit but rather increased the cost of production.
