Effect of Spacings on the Growth and Yield of Bambara Groundnut (Vigna Subterrananea (L) Verde.) in Asaba Delta State (Published)

A field experiment was conducted at Teaching and Research Farm of Delta state University, Asaba Campus to study the effect of spacing on the growth and yields of Bambara groundnuts. The design was randomized complete block replicated three times. The spacing were  15×30 cm, 25×30 cm, 35×30 cm and 45×30 cm giving a plant population densities of 22,222, 13,333, 9,524 and 7,407 plants/ha, respectively. Results indicated that the number of pods plants-1 and grain yield/ha-1 of Bambara groundnuts increased with increased planting density. The study showed that Bambara groundnuts performed better at high densities for growth and yield than low densities. Plants with population density of 22,222 plants/ha (15×30 cm) had the best yield (3920 kg/ha), followed by 13,333 plants/ha (25×30 cm) with the yield of 3768kg/ha and the least 7,407 plants/ha population density (45x30cm) with yield of 2478kg/ha. It is recommended that Bambara groundnut should be planted at a spacing of 15 x 30 cm in a rain forest zone of Asaba, Delta State for maximum productivity.

Effect of Neem Seed Cake and Inorganic Fertilizer on Yield of Tomato and Soil Properties in Northern Guinea Savanna of Nigeria (Published)

Field trials were conducted at the Institute for Agricultural Research Irrigation Farm, Samaru Zaria, in the northern Guinea savanna ecological zone of Nigeria in 2009/2010, 2010/2011 dry seasons to study the integrated effect of neem seed cake and inorganic fertilizer on tomato.  The treatments consisted of three levels of NSC (0, 2 and 4 t ha-1) and four levels of inorganic fertilizer (0, ¼, ½ and Full Fertilizer recommended Rate (FFR, NPK 15:15:15) for tomato in northern Guinea savanna of Nigeria.  The treatments were laid out in a Randomized Complete Block Design (RCBD) with three replications. Mean fruit weight and fruit yield were determined.  Matured ripe fruits were analyzed for biochemical properties such as reducing sugars, total soluble solids, ascorbic acid and titratable acidity.  Effect of treatments on soil properties were also determined by analyzing the treated soils after harvest.  Results obtained showed that tomato responded positively to the treatments.  Highest fruit yield of 14.54 and 19.70 t/ha were obtained from 2tons/ha neem seed cake + ½ Fertilizer rate in 2009/2010 and 2010/2011 respectively.  Although the effect of complementary application of NSC and inorganic fertilizer on tomato was not significant among the treatments of such combinations, highest fruit yield increase over the control were 103.1% and197% for 2009/2010 and 2010/2011 respectively. Effects of treatments on ascorbic acid, titratable acidity, total soluble solids and reducing sugars were not significant. The concentrations of plant tissue N, P and K were higher than the control at the end of second year of experiment. In the first year of trial pH (H2O) varied from 6.2 to 6.7, whereas in the second year, it varied from 6.1 to 6.3.  The values of soil OC and N increased over the years. Combinations of 2NC + ½ FR and 4NC + ½ FR proved superior for tomato fruit yield and mean fruit weight than other treatments in this study.

Impact of Organic and Folia Fertilizer Application on the Growth, Yield and Medicinal Potential of Hybiscus Sabdariffa L (Published)

The effect of organic (poultry manure) and folia fertilizer application on the growth, yield and phytochemical composition of Hibiscus sabdariffa was investigated in planting pot experiments. Seeds of this plant were sown in soil treated with organic fertilizer at 40, 80 and 120 g separately and also supplemented with folia fertilizer two weeks after germination. Some seedlings with no organic fertilizer application were also sprayed with folia fertilizer, thus making seven treatments in all. No organic or folia fertilizer served as control.  Application of 120 g poultry manure in combination with folia fertilizer produced the highest plant height (98.23 cm), dry shoot weigh plant-1 (24.66 g) and number of fruits plant-1 (19.33). The highest leaf number plant-1 (164.00), fresh (28.06 g) and dry (4.43 g) fruit weight was recorded in plants treated with 120 g poultry manure. More so, alkaloids, anthocyanins, flavonoids, phenols, saponins, and tannins were found in the calyces of Hibiscus sabdariffa with or without organic and foliar fertilizer. However, treatments   with organic fertilizer singly or in combination with folia fertilizer significantly (p < 0.05) increased the phytochemical contents in the calyces of the plant. Interestingly, 120 g poultry manure had the greatest impact. The use of organic fertilizer in the cultivation of this medicinal plant should be encouraged as they could enhance its better growth, good yield and medicinal value under safe agricultural condition.

Impact of Organic and Inorganic Fertilizers on the Yield, Lycopene and Some Minerals in Tomato (Lycopersicum Esculentum Mill) Fruit. (Published)

Lycopene, an antioxidant contained in tomatoes, which is found to reduce the risk of cancer can be affected by management practices. A field experiment was carried out behind Recreational Centre of Institute of Agricultural Research and Training (I.A.R&T), Moor Plantation, Ibadan (latitude 7o22’N and longitude 3o50’SE). The experiment was done during the rainy season of 2014 between May and July. Effectiveness of organic and inorganic fertilizers in the growth, yield and nutrient composition of tomato were compared in a Randomized Complete Block Design (RCBD) with four treatments which include sole application each of NPK and Organic fertilizer, there complimentary application and the control replicated three times. Tomato premier (variety UC-82-B) was planted at 50 cm × 50 cm at 1 seedling per stand. The Aleshinloye Compost (Grade B) organic fertilizer was applied two weeks before transplanting at 100 kgN/ha at the appropriate plots while NPK 15:15:15 was applied 2 weeks after transplanting at 100kgN/ha.  Parameters assessed were plant height (cm), number of leaves, number of branches, stem girth (mm) while the yield parameters observed were days to 50 % flowering, number of flowers/plot, number of flowers aborted, number of rotten fruits/plot, number of fruits/plot and fruit weight (g). Nutrient component determined in the laboratory were lycopene, potassium and sodium. The fertilizer sources did not affect the growth of tomato but were better than the control plots. At 8 weeks after transplanting (8 WAT), NPK 15:15:15 treated plant had more flower abortion of 34.7 than the lowest flower abortion of 24.67 from the control plots. NPK 15:15:15 at 100 kgN/ha gave the highest fruit yield of 18.60 t/ha while the lowest yield (4.07 t/ha) was obtained from the control plots. Highest value of lycopene content of 2.65 % was found in plots supplied with NPK but is comparable with the control plot but higher than other sources. Potassium content of 20.80 % was lowest in NPK plots while potassium accumulation of 23.20% was highest in the control but not different statistically from each other. Sodium content had highest percentage in untreated plot with 0.43 % and sodium ion was lowest in NPK + organic treated plot which have the value of 0.31%.
