Millions of people in the dry lands of Central and East Africa, and South of India depend on finger millet as an important source of food to them (CGIAR, 2001). Finger millet is one of the most neglected and underutilized crops. Additionally, the crop has received limited research attention compared to wheat, rice, and maize (FAO, 2011). Therefore, production challenges such as those caused by weeds like goose grass <em>Elusine indica</em> remain at large. Manual weeding is the commonly employed weed control method in finger millet production, but is expensive and labour intensive. The current study was set to evaluate the influence of weed management practices on finger millet growth and yield components. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates. The plots measured 2 by 2m with a border width of 1m. The treatments included Pendimethalin, Dimethyl amine, Metolachlor, Metribuzin, Atrazine (at three rates each 1.0, 1.5 and 2.0 l/ha), No weeding and Hand weeding. Data was collected on the number of weed species, weed biomass, number of basal tillers, herbicide phytotoxicity, weed and crop heights, number of panicles, weight of panicles, weight of un-threshed and threshed grains and 1000 grain weight. Data was analyzed using one-way ANOVA using GenStat version 15.1. Application of Pendimethalin at 1.5 and 2.0 L/ha Active Ingredient (AI), resulted in weed optimal control and least phytotoxicity. Results also indicated that the height of finger millet was significantly (p&lt;0.001) higher where the herbicides were applied. Lower weed biomass was also positively correlated with higher crop height, more panicles, high unthreshed and threshed weights and a 1000 grain weight. Application of 2,4D at rates of 1.5L and 2.0L resulted in significantly taller plants 33.00 cm, than the other weed management methods. Finger millet under Pendimethalin 1.5 L gave the highest number of 86 panicles while Atrazine 2.0L and Pendimethalin1.5L methods of weed control, had significantly higher weight compared to all the other treatments. The 1000 seed mass across the treatments averaged 2.31 g while the on the untreated treatments had an average of 1.54 g. Weed control using pre emergence herbicides significantly (p&lt;0.001) increased the yields of finger millet.</p> Mayaka Justus Mogaka Korir Kibet Nicholas Wafula Wekha Nelson Joseph P.

The aqueous extracts of the plants seeds were obtained using standard procedures. The phytochemical screening revealed the presence of alkaloids, saponins, flavonoids, terpenoids and phenols in the aqueous extracts of the plants seeds, while tannins was absent in the extract of <em>Aframomum melegueta. </em>Flavonoids and phenols revealed the highest antioxidant potential of the plants quantitatively at 0.1 g/m. The proximate contents of the plants seeds showed the level of crude contents ranging from moisture&nbsp; (7.34% ± 0.01 and 13.74% ± 0.03), fiber (28.33% ± 0.02 and 16.23% ± 0.02), protein (21.03% ± 0.02 and 10.79% ± 0.05), fat (7.13% ± 0.02 and 27.94% ± 0.10) and carbohydrates (32.76% ± 0.03 and 26.53% ± 0.02) respectively. The results also revealed the presence of potassium (63.50% ± 0.2 ppm and 64.20% ± 0.2 ppm), calcium (7.54% ± 0.2 ppm and 10.40% ± 0.2 ppm) and magnesium (9.05% ± 0.2 ppm and 9.11% ± 0.2 ppm) in the two plants seeds respectively. Therefore this study justifies the local use of <em>Aframomum melegueta </em>(<em>Ataare</em>) and<em> Syzygium aromaticum </em>(<em>Kanafuru</em>) as sources of medicine to manage and alleviate various symptoms associated with respiratory diseases and health conditions.</p> F.

The experiment was performed to investigate the effects of density and fertilization on the fruit yield and quality, economic efficiency of <em>Solanum lycopersicum </em>L. at Duc Trong district of Lam Dong province. The density (50,000; 33,000; 25.000 plants ha<sup>-1</sup>) and the fertilizer rates (240N – 100P<sub>2</sub>O<sub>5</sub> – 275K<sub>2</sub>O; 300N – 125P<sub>2</sub>O<sub>5</sub> – 344K<sub>2</sub>O; 360N – 150P<sub>2</sub>O<sub>5</sub> – 413K<sub>2</sub>O kg and 420N – 175P<sub>2</sub>O<sub>5</sub> – 482K<sub>2</sub>O kg ha<sup>-1</sup>) were studied in a completely randomised split plot design with three blocks. The fertilizer rate (420N – 175P<sub>2</sub>O<sub>5</sub> – 482K<sub>2</sub>O kg ha<sup>-1</sup>) was produced the highest height (562.39 cm), fruit setting rate (69.87%), number of fruit per plant (95.65 fruits), average fruit weight (106.37 g), fruit yield (441.11 tons ha<sup>-1</sup>) and marketable fruit yield (204.31 tons ha<sup>-1</sup>). The density (25,000 plants ha<sup>-1</sup>) gave the highest fruit setting rate (75.35%), number of fruit per plant (94.84 fruits), average fruit weight (113.24 g), individual fruit yield (10.02 kg per plant) and fruit yield (501.17 tons ha<sup>-1</sup>). The combination of density (25,000 plants ha<sup>-1</sup>) and fertilizer rate (420N – 175P<sub>2</sub>O<sub>5</sub> – 482K<sub>2</sub>O kg ha<sup>-1</sup>) have the highest fruit yield (613.5 tons ha<sup>-1</sup>), marketable fruit yield (223.91 tons ha<sup>-1</sup>) and rate of return (2.44). In addition, this combination was the best density and fertilizer level management strategy for greenhouse-grown Lahay 334 tomato cultivar in Lam Dong province, Vietnam.</p> Mai Hai Chau Ngo Xuan Chinh ##submission.copyrightStatement## 2021-10-05 2021-10-05 22 31 10.9734/aprj/2021/v8i330177
