“…Hemorrhage plant, Siam weed, giant sensitive plant, and giant potato are prominent weeds in cassava fields (Alabi et al 2001(Alabi et al , 2004aNzegbule and Ogunremi 1995;Tarawali et al 2013;Wakjira 2011). Siam weed and giant sensitive plant are reported as invasive species (Ikuenobe and Ayeni 1998;Uyi et al 2014) that reduce cassava root yield in the Humid Forest and Derived Savanna agroecologies in Nigeria. Alabi et al (2001) reported up to 85% root yield loss due to competition from giant sensitive plant and Nzegbule and Ogunremi (1995) reported significant cassava root yield reduction from competition with Siam weed.…”

Screening preemergence herbicides for weed control in cassava

Weed competition severely constrains cassava root yield in sub-Saharan Africa; thus, good weed control measures, including the use of herbicides, are increasingly important. Herbicide trials were conducted at five locations across eastern, western, and north-central Nigeria over two cropping seasons (2014 and 2015). Nineteen premixed PRE herbicides applied at different rates were evaluated for efficacy on weeds and selectivity on cassava. Manual hoe-weeding at 4, 8, and 12 wk after planting (WAP) and two S-metolachlor + atrazine treatments commonly used by cassava growers were included for comparison. Six of the 19 PRE herbicide treatments (indaziflam + isoxaflutole, indaziflam + metribuzin, flumioxazin + pyroxasulfone, isoxaflutole, acetochlor + atrazine + terbuthylazine, and terbuthylazine + S-metolachlor) consistently provided 80% to 98% broadleaf and grass weed control up to 8 wk after treatment. Overall, PRE herbicide treatments and cassava yield were significantly positively correlated. Herbicide treatments terbuthylazine + S-metolachlor, flumioxazin + pyroxasulfone, diflufenican + flufenacet + flurtamone (respectively, 60 + 60 + 60, 120 + 120 + 120, 90 + 360 + 120, and 135 + 360 + 180 g ha−1), acetochlor + atrazine + terbuthylazine (875 + 875 + 875 g ha−1), S-metolachlor + atrazine (870 + 1,110 g ha−1), oxyfluorfen (240 g ha−1), indaziflam + isoxaflutole (75 + 225 g ha−1), indaziflam + metribuzin (75 + 960 g ha−1), and aclonifen + isoxaflutole (500 + 75 g ha−1) contributed to yields exceeding twice the Nigerian national average of 8.76 tonnes ha−1. These treatments had root yields of 1.4 to 2 times higher than plots that had been hoe-weeded three times. There were some adverse herbicide treatment effects such as delayed cassava sprouting and temporary leaf bleaching observed in indaziflam and diflufenican + flufenacet + flurtamone treatments, whereas sulfentrazone caused prolonged leaf crinkling. The PRE applications alone at rates safe for cassava did not provide adequate season-long weed control; supplemental POST weed control is needed about 10 WAP for satisfactory season-long control.

“…Usually Chromolaena odorata RL K&R (Siam weed) constitutes an aggressive weed that is difficult to control in young single or mixed crop plantations of oil palm, rubber and cocoa in Nigeria. It also easily colonizes abandoned land in the rain forest and southern savannas of Nigeria and other parts of West Africa (Ivens, 1972; De Rouw, 1995; Ikuenobe & Ayeni, 1998) constituting an important member of the fallow vegetation. It is also a dominant fallow species in slash and burn agriculture of some parts of Asia including Thailand and India (Kushwaha et al ., 1981; Roder et al ., 1995).…”

Fallow management is a major strategy for weed control and soil fertility restoration in tropical farming systems. From 1995 to 1998, weed infestation was evaluated in plots managed under 0, 1, 2 and 3 year fallow durations of (1) a natural bush fallow dominated by Chromolaena odorata;(2) a planted Mucuna pruriens fallow; and (3) a modified bush fallow without C. odorata. The study was conducted at the Nigerian Institute for Oil Palm Research (NIFOR), Benin City, Nigeria. The 3 · 4 factorial experiment was set up in a split plot arrangement. The three fallow types were the main plots and the four fallow durations were the subplots. Each year, the subplots were planted to maize (Zea mays, cv. TZSR-W) as appropriate and harvested 14 weeks after planting for yield comparison. Continuous cropping and the modified natural bush fallow increased weed diversity and biomass. Irrespective of fallow type, weed infestation was more gradual in the first year of cropping after fallow than in subsequent cropping years. Regardless of cropping intensity, C. odorata and M. pruriens fallows promoted broad-leaved weeds, chiefly Ageratum conyzoides, Tridax procumbens and Phyllanthus amarus, whereas the modified bush fallow promoted grasses. Maize grain yield was higher in the C. odorata and M. pruriens fallows than in the modified bush fallow, but the yield difference diminished with cropping intensity.

“…Para el cultivo de maíz, la aplicación es de 0.85 kg/ha y finalmente canola con 0.14 Kg/ha. Por otro lado, el cultivo de palma presentó los valores más altos con una aplicación del componente activo de glifosato de 2 kilos por hectárea según estudio realizado por Ikuenobe et al (1998). La deuda de carbono consiste en el balance de emisiones de dióxido de carbono debido a la conversión de ecosistemas nativos para la producción de biodiesel mediante la implantación de monocultivos.…”

Macbeth model is a multicriteria tool for the multicriteria decision making that has been used in different projects and studies of renewable energies. The purpose of this paper was apply the software Macbeth for the evaluation of canola, corn, palm and soy crops taking in to account technician, environmental and economic criterias and their weights. Canola crop was the best option for the biodiesel production, with a global score of 74 points because of their good score in environmental criterias, wich had a higher weight than the other criterias. Corn crop was the second positioned, presenting good results in all criterias, followed by palm crop. The final one was soy crop with 36,67 points in this analysis.
