Two field experiments were conducted at the Research Farm of the Ibrahim Badamasi Babangida University, Lapai, Niger State during the 2018 and 2019 rainy seasons to determine the effect of neem fertilizer rates and weed control methods on the growth and yields of soybeans. The experimental treatments were made up of four neem fertilizer rates (0, 50, 100 and 150 kg ha-1) and six weed control methods (pendimethalin at 1.5 kg a.i ha-1 followed by one hoe weeding, pendimethalin at 2.0 kg a.i. ha-1 followed by diuron at 1.5 kg a.i ha-1, weeding once at 3 WAS, weeding twice at 3 and 6 WAS, weed free and weedy check. The experiment was a 3 × 3 factorial experiment laid out in a Randomize complete block design replicated three times. TGX 1448 – 2E variety of soybean was used for the study. Result showed that weed control efficiency was better with the use of 150 kg ha-1 of neem fertilizer, while decrease in weed dry matter was obtained at 50 kg ha-1. Increase in number of leaves and leaf area were encouraged with 150 kg ha-1 of neem fertilizer. Weed free treatments recorded the highest grain yield and 100 seed weight of soybean. Pendimethalin at 1.5 or 2.0 kg a.i ha-1 supplemented with one hoe weeding or diuron at 1.5 kg a.i ha-1 respectively can be an alternative for better control of weeds to obtain greater yield of soybean in the study area.

Chicken weed is a significant weed in India and it occurs under onion cultivated field at Birnin Kebbi in the Sudan Savannah, Nigeria. On-farm experiment was conducted at Birnin Kebbi during the 2017/2018 and 2018/2019 dry season to evaluate the effect of plant population and weed control methods on the management of chicken weed (Portulaca quadrifida) alongside other weeds in onion field. The experiment consisted of three plant populations (500,000, 333,333 and 250,000 plants per hectare) and twelve weed control methods (Pendimethalin at 1.0 kg a.i. ha-1, + 1Hw; pendimethalin at 1.5 kg a.i. ha-1 + fluazifop-p-butyl at 2.0 kg a.i. ha-1; pendimethalin at 2.0 kg a.i. ha-1; butachlor at 2.0 kg a.i. ha-1 + 1Hw; butachlor at 2.8 kg a.i. ha-1 + oxyfluorfen at 1.0 kg a.i. ha-1; butachlor at 3.6 kg a.i. ha-1; fluazifop-p-butyl at 2.0 kg a.i. ha-1; oxyfluorfen at 1.0 kg a.i. ha-1 + 1Hw; hoe weeding at 3 (WAT); hoe weeding at 3 and 6 WAT; weed free and weedy check). The experiment was laid out in a randomized complete Block design replicated three times. Results showed that weed, growth and yield parameters were not significantly affected by plant population. Pendimethalin at 1.5 kg a.i. ha-1 + fluazifop-p-butyl at 2.0 kg a.i. ha-1 and weed free plots consistently recorded the lowest weed cover and highest weed control efficiency. Butachlor at 2.0 kg a.i. ha-1 + 1 Hw recorded the lowest crop injury score. Increase in plant height was observed when pendimethalin at 1.0 and 1.5 kg a.i. ha-1 + 1 Hw and fluazifop-p-butyl at 2.0 kg a.i. ha-1 respectively was applied, while application of pendimethalin at 2.0 kg a.i. ha-1 and butachlor at 2.0 kg a.i. ha-1 + 1 Hw recorded highest number of leaves and leaf area. Cured bulb and marketable bulb yield were greater with the use of pendimethalin and butachlor at 1.0 and 1.5 kg a.i. ha-1 + 1 Hw and the pooled data respectively. Application of pendimethalin and butachlor at the rate of 1.0 and 2.0 kg a.i. ha-1 followed by 1 Hw at 6 WAT respectively was therefore recommended for the control of chicken weed alongside other weed species in the ecology

To evaluate performance of sesame varieties as affected by poultry manure and weed control methods. The treatments consisted of five weed control treatments (pre-emergence application of ButachlorEC50%,  hoe weeding at 3WAS +pre-emergence butachlor EC50%, pre-emergence butachlor EC50%+hoe weeding at 3 and 6WAS, hoe weeding @ 3 and 6WAS and weedy check), three level of poultry manure (5, 10, and 15t/ha) and three sesame varieties (Ben 01, Yandev 55 and Ben 04E. The treatments were laid out in split plot design and replicated three times. The results indicated that weed control methods had significant effect (0.05) on the sesame growth and seed yield comparable to hoe weeding control at 3 and 6WAS where plant height number of leaves,  capsule number per plant and seed yield of sesame were significant higher with the application of butachlor plus hoe weeding at 3 and 6WAS compared to others weed control methods.  Poultry manure application on sesame as 15t/ha gave taller plant height, more number of leaves, higher sesame dry weight, longer capsule length and seed yield of sesame than the other rates while Ben 01(455 and 1043 ) perform better than the others two varieties (Yandev 498, 756 and Ben4E 522 and 765 ) for 2017 and 2018 seasons.  In conclusion,

Abstract Successful cultivation of maize depends largely on efficient weed control, adequate supply of essential nutrients and sufficient soil moisture. Screenhouse and field trials were conducted at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta, Nigeria during the early and late cropping season of 2013 to evaluate effects of biochar integrated with manual weeding and pre-emergence herbicides on weed control efficiency and productivity of maize. The screenhouse trial was a 6 × 5 factorial experiment fitted into Completely Randomized Design in three replicates. The two factors were biochar: 0, 2, 4, 6, 8 and 10 t ha−1 and weed control methods: weedy check, hoe weeding at 6 Weeks After Sowing (WAS), hoe weeding at 3, 6, and 9 WAS, pre-emergence herbicide application (Codal Gold) at 1.0 and 2.0 kg a.i./ha−1. The field trial was laid out in split-plot arrangement fitted into Randomized Complete Block Design with three replicates. The three main treatments plots on the field consisted of the optimum rates of biochar obtained in the screenhouse (10 t ha−1) compared with 20 t ha−1 and 0 t ha−1 which served as the control. The sub-plots treatments consisted of weed control methods used in the screen house experiment. Data were collected on grain yield and weed dry matter. The result showed that biochar at 10 and 20 t ha−1 in the screenhouse and field trials, respectively, resulted in significantly (P < 0.05) higher grain yield compared with other rates tested. Highest grain yield was obtained in pots hoe weeded thrice at 3, 6 and 9 WAS. Whereas similar grain yield was recorded in plot weeded once at 6 WAS and that hoe weeded at 3, 6 and 9 WAS in the field experiment. Biochar application of 20 t ha−1 gave optimum maize yield. Among the weed control treatments manual weeding either at 6 WAS or at 3, 6 and 9 WAS recorded the highest grain yields. Therefore, incorporation of biochar with either preemergence herbicide or manual hoe weeding would enhance the growth and yield of maize.

Field trial was conducted at the Cocoa Research Institute of Nigeria (CRIN), Ajassor substation, Cross River State, Nigeria between 2015 and 2017 to evaluate the effect of different weed control methods on the growth and yield of cocoa during their early years of establishment. Glyphosate and paraquat were applied at 480, 720, 960 and 1440 gram of active ingredient per hectare using very low volume (g a.i. ha-1 vlv) while manual weeding (i.e. slashing with cutlass) was used as the control. A Nigeria commercial cocoa variety Tc series, also known as 18-month cocoa, was established at a CRIN recommended spacing of 3 x 3 m, laid out in a Complete Randomized Block Design with four replications. All young cocoa stands were ring weeded at 50 cm diameter and covered with black polythene bags before the spraying of herbicides during the first six months of establishment to reduce injury that could result from the drifting of herbicide solution to plants during their early growth stage. Data was collected on the plant height, stem girth and number of leaves of cocoa plants while the cocoa dry beans weight and labour cost for each treatment were determined. The results showed that 960 g a.i. ha-1 vlv was the best herbicide application rate while plots under glyphosate at 960 g a.i. ha-1 vlv produced significantly higher values of plant height, stem girth and number of leaves at (p=0.05) than both paraquat at 960 g a.i. ha-1 vlv and manual weeding. Labour cost for controlling weeds with either glyphosate or paraquat at all application rates were considerably lower than cost for control (manual weeding). Glyphosate at 960 g a.i. ha-1 vlv is recommended for weed control in cocoa plantation because it encouraged higher growth and yield performance of cocoa than other treatments, had considerably cheaper cost of application than paraquat at 960 g a.i. ha-1 vlv and manual weeding, and it also ensured a weed-free environment over a longer period of time than the other treatments.

Tithonia diversifolia has become a significant agronomic problem to optimum arable crop production in Nigeria which has necessitated effective and timely control if the good yield is expected on infested soil. This study compared the performance of water yam under different weed control methods on Tithonia infested plot at Ogunba village near Baaya-Oje in Surulere Local Government area of Ogbomoso, Oyo State during the 2015 growing season. Eight (8) control treatments were evaluated namely: Weed control with Atrazine, Diuron, 2 hoe weeding, 3 hoe weeding, Black plastic mulch, grass mulch, Diuron + Atrazine + Plastic mulch (IWM) and unweeded plot. The three (3) hoe weeding and the unweeded plot served as the control treatments. The experiment was laid out in a Randomized complete block design with three replicates. Yam setts were planted at a spacing of    1 m x 1 m to give a population of 10000 plants/ha. Atrazine and Diuron were applied at the rate of 2.5 kg a.i/ha, 2 hoe weeding was done at 3 and 6 weeks after planting (WAP), 3 hoe weeding was done at 3,6 and 9 WAP, while grass mulch was applied at the rate of 5 tons/ha. In IWM, Atrazine and Diuron were applied each at the half recommended rate (1.25 kg/ha) before applying plastic mulch. The treatments were applied pre-emergently on a rain wetted soil after planting. Data were collected on growth and yield parameters of yam as well as on Tithonia weed population and dry matter yield. Results showed that weed control methods significantly (P < 0.05) influenced water yam yield. The highest tuber yield (21 tons/ha) in plastic mulch was comparable to IWM (20 tons/ha), 3 hoe weeding (19 tons/ha) and 2 hoe weeding (18 tons/ha). Grass mulch (16 tons/ha), Diuron (15 tons/ha), Atrazine (14 tons/ha) were also not significantly (P > 0.05) different. Thus, it may be concluded that plastic much is the most efficient of the methods for weed control in yam. The implication of this finding is discussed.

Field trials were conducted at the Teaching and Research Farm of the Kwara State University, Malete, Nigeria, to determine the effect of plant spacing and weed control methods on weed infestation, growth and yield of okra during the 2016 and 2017 cropping seasons. The experiment consisted of twelve treatments comprising six weed control methods and two plant spacings. The method of weed control consisted of pre-emergence application of pendimethalin at 1.0 kg a.i. ha-1, pendimethalin at 2.0 kg a.i. ha-1, pendimathalin at 1.0 kg a.i. ha-1 + one supplementary hoe weeding (SHW) at 6 weeks after sowing (WAS), two hoe weedings at 3 and 6 weeks after sowing (WAS), weeding at 4 and 8 weeks after sowing (WAS) and a weedy check. The plant spacings were 60cm x 30cm and 60cm x 50cm. These treatments were laid out in a randomized complete block design (RCBD) with split plot arrangements and three replications. Weed control and plant spacing treatments were allocated to the subplots and the main plot respectively. Results showed that a plant spacing of 60cm x 30cm minimized weed infestation and resulted in a higher total number of pods/plot and okra fresh weight, while pendimethalin at 1.0 kg a.i. ha-1 + one supplementary hoe weeding at 6 WAS minimized weed infestation in the plots, and led to the highest total number of pods and yield of okra. This combination also promoted higher economic returns.

Soybean is a type of secondary crop that is widely cultivated and used as raw material for tofu, tempe, milk, and so on by the people of Indonesia. Soybean consumption is always increasing but soybean production has decreased. This study aims to obtain the optimum dose of Bokashi fertilizer on plant growth and yield in Ultisol. The study was carried out in Medan Baru, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City from December 2018 to April 2019. This study used a Completely Randomized Block Design (RCBD) with one factor, namely the dose of Bokashi fertilizer with five levels, namely 0 tons ha-1, 25 tons ha-1, 35 tons ha-1, 45 tons ha-1, and 55 tons ha-1. The results showed that the optimum dose of Bokashi fertilizer was not found in the growth component or yield component. The dose of Bokashi fertilizer had a significant effect (p<0.05) on the growth of Bokashi and the number of leaves.

Field experiments were conducted during 2017 and 2018 cropping seasons at Illah, Delta North ecological zone of Nigeria to investigate the appropriate rates of NPK fertilizer and irrigation intervals in relation to yield response of water melon (Citrullus lunatus). The site had sandy loam texture, low in organic carbon (0.38%), low in total nitrogen (0.064%), available phosphorus (6.83 mgkg-1) and cation exchange capacity (6.74 cmolkg-1). The fertilizer rates were (0:0:0), (50:25:25), (80:40:40), and (120:60:60) KgN, P2O5 and K2O/ha and irrigation regimes of 6:12:18 days. It was a factorial experiment laid out in a Randomized Complete Block Design with three replicates. Results indicated that increase in fertilizer rates from 0:0:0 to 80:40:40 kg/ha significantly increased growth and fruit yield. Further increase to 120:60:60 kg/ha depressed yield. Increase irrigation intervals from 6 -12 days also influenced significantly growth and fruit yield and further increase to 18 days intervals affected negatively the parameters. Interaction effects between fertilizer x irrigation intervals were not significant. Correlation analysis showed that the growth and yield characters were significant and positively correlated with fruit yield. Results indicated that fertilizer rates and 12 days irrigation interval were adequate and recommended for increased production of watermelon in the study area.

Weed interference is a major threat to rice production, leading to high yield reduction and reduced profitability. Therefore, field experiments were conducted to evaluate the effect of the different timings of weed control on the growth and yield of upland rice in the 2015 and 2016 cropping seasons. The treatments consisted of periods when the crop was allowed to be weed-infested for the first 3, 6 and 9 weeks after sowing (WAS) and periods when the weeds were controlled for the first 3, 6 and 9 WAS. Two treatments of weed infestation and weed control until harvest were also included as the checks in a randomized complete block design with three replications. In both years, rice grain yields ranged from 0.6 to 0.8 t ha-1 in plots kept weed-infested until harvest, and from 3.5 to 3.9 t ha-1 in plots kept weed-free until harvest, indicating a 79-83% yield loss with uncontrolled weed growth. Weed infestation for the first 3 WAS did not cause a significant reduction in the growth and yield of rice provided the weeds were removed thereafter. However, the delay in weed control until 9 WAS reduced rice growth and resulted in irrevocable yield reduction. It was only necessary to remove the weeds between 3 and 9 WAS for optimum grain yield, as no significant yield increase was observed in weed control after 9 WAS in both years. This study showed that weed control between 3 and 9 WAS would give the optimum growth and yield of upland rice.
