Effect of Organic (Cow Dung Slurry) and Inorganic (N: P: K 15:15:15) Fertilizer on the Growth and Yield of Tomato (Lycopersicon Lycopersicum) in Anyigba, Kogi State, Nigeria (Published)

A pot experiment was conducted in April 2018 in faculty of Agriculture, Kogi state university, Anyigba. The experiment was laid in a completely randomized design (CRD) with five treatments in four replications and results obtained were subjected to analysis using ANOVA and means were separated at 5% level of probability using Fisher Least Significant Difference Test. The treatment consisted of a control (T0), 2 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T1), 4 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T2), 6 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T3), 8 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T4).Data were collected on plant height, number of leaves, stem girth, number of branches, number of fruit per plant, and fruit diameter respectively. It was observed that the organic and inorganic manure used increased the soil physical-chemical properties as well as the performance parameters of the test crop (Tomato). Recommendation was made at the rate of 6t/ha of cow dung slurry +50kg of NPK 15:15:15 (T4) for optimum yield and performance of tomato.

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.

Growth and Fruit Yield of Tomato As Influenced by Combined Use of Organic and Inorganic Fertilizer in Kabba, Nigeria (Published)

Field experiments were conducted to investigate the effects of integrated use of chemical and organic fertilizers on growth and fruit yield of tomato in Kabba College of Agriculture. The experiment involved five treatments which are as follows: 125kh/ha NPK+3t/ha poultry manure, 125kg/ha NPK+3t/ha cow dung, 125kg/ha NPK+3t/ha kitchen waste, 125kg/ha NPK 15:15:15 and Control. The treatments were laid out in a Randomized Complete Block Design (RCBD) and replicated four times. The parameters taken on soil chemical properties are soil pH, total nitrogen, available phosphorus and soil organic matter. Growth and yield parameters taken are as follows: plant height (cm), number of leaves, and stem girth (cm), number of fruit per plant, fruit length (cm), fruit diameter (cm) and yield per land area (kg/ha). Result obtained from parameters studied (Plant height, leaf numbers, branch number, stem girth, fruit number per plant and fruits weight) revealed that tomato performed better (P<0.05) with the application of 125kg/ha NPK+3t/ha poultry manure application. The also, study showed that use of inorganic and organic fertilizer had better effects on growth and yield of tomato. Therefore, for good yield and better productivity of tomato, a combination of 125kg/ha NPK fertilizer + 3t/ha poultry waste is recommended for tomato production in the study area.
