Research paper thumbnail of Growth Responses of Okra (<i>Albemoschus esculentus)</i> and Jute Mallow (<i>Corchorus oitorius)</i> to Water Stress and Non-Water Stress Conditions

Therefore, a screen house study was carried out to determine the effect of water stress on growth and yield of Okra and Jute mallow. 7 litre capacity each bucket was filled with 10 kg of soil and arranged in a completely randomized design with three replicates. There were four irrigation regimes based on field capacity; 100% FC (control), 75% FC, 50% FC, and 25% FC Seeds from local source were sown at the rate of three seeds per pot and later thinned to two seedlings per pot two weeks after sowing (WAS). Data on growth parameters; plant height, stem girth and number of leaves were collected at two week interval up to 10 WAS while total fruit yield and biomass yield, for okra and jute mallow respectively, were determined at harvest. Data collected were subjected to analysis of variance (ANOVA) and the means were separated using least significant difference at p<0.05. Okra growth and fruit yield were significantly (p<0.05) affected by field capacities; 75% FC produced significantly (p<0.05) tallest plant at 10 WAS (25.3 cm) while 25% FC gave shortest plant height (13.9 cm). Number of leaves at 10 WAS followed similar trend as plant height. Irrigation regimes did not significantly (p<0.05) affect fruit yield however, 75% FC recorded highest fruit yield than other field capacities. At 10 WAS, jute mallow plant height under 100, 75 and 50% FC were significantly (p<0.05) tallest height than at 25% FC. Stem girth followed the same trend as plant height. However, at 10 WAS, 75% FC produced significantly (p<0.05) higher number of leaves and biomass yield than other treatments. It could be concluded from the study that 75 % FC was best for growth, fruit yield and biomass yield of okra and jute mallow production.

Twelve biochars were produced from SD and TD with or without PM at three slow pyrolysis HRs of 5, 10 and 20 minutes in completely randomized design with three replications. Dominant biochar parameters contributing to BY and ash content were reported. Results indicated PM spiking and HR significantly (p < 0.001) improved BY and nutrient quality irrespective of plant biomass type. The BY increased by 107% (5 min HR) and 79% (10 min HR) with PM spiking while ash content increased with increasing HR by 599 and 305% following PM spiking in TD and SD respectively. 20 and 10 minute HRs enhanced N and P contents in SD and TD biochar respectively. PM spiking and increasing HR from 10 to 20 minutes reduced biochar organic C by 15...

Therefore, field experiments were conducted at Ladoke Akintola University of Technology Teaching and Research Farm, Ogbomoso, Southwestern Nigeria, in 2015 and 2016 to evaluate the influence of soil compaction on selected soil physical properties, growth, yield and nutrient uptake of soybean (Glycine max.). The experiment was arranged in a randomized complete block design and replicated three times. There were four treatments which consisted of 0 (no pass of tractor wheel), 4, 8, and 14 passes of tractor wheel totaling 16 treatments. Soil physical properties determined were; bulk density, total porosity, macroporosity and saturated hydraulic conductivity. While data recorded on soybean were plant height, stem girth, number of leaves, biomass and grain yield.

The study was a split plot in randomized complete block design (RCBD). Tillage was the main treatment having three types; manual clearing (MC), ploughed twice (PT) followed by ridged (RT) while the sub plot was sesame varieties; 03L+ Tithonia, Ex-Sudan and E8. The result showed that soil physical properties and sesame varieties were not generally affected by tillage practices during the two years of the experiment. However, there was significant interaction of tillage and sesame varieties on soil microporosity and available water content (AWC) in 2013. RT increased AWC in 2013 and 2014 compared to MC and PT although, the treatments were statistically similar. RT significantly increased stem girth, number of leaves, and number of branches of sesame in 2013. Ex-Sudan variety produced significantly higher number of leaves and branches in 2013. However, E8 produced higher number of capsules per plant and seed yield. In 2013, interaction between tillage practices and sesame variety were significant on microporosity, available water content and plant height. Ridge tillage and E8 variety gave the best result in terms of improved soil physical properties and yield, therefore it is recommended in this study area.

A ten kilogram of soil was packed in the pots with an initial bulk density of 1.05 Mg m-3, then it were compressed to1.57, 1.72, 1.88, 2.04, and 2.42 Mg m-3. The research was conducted in a completely randomized design with three replications. Groundnut seeds were sown in pots and the plant growth data were collected in a 2-week interval while force and energy of harvesting and soil loss due to groundnut harvesting were determined at 12 weeks after sowing. Data were analyzed using ANOVA and Fishers LSD at P= 0.05. Soil compacted to1.88 Mgm-3 produced more taller plant, more higher number of leaves and branches than control. Soil compaction significantly reduced the number of pods, roots, and fresh root weight compared to control. Bulk density (2.04 Mgm-3) required a significantly higher force (42.47 N...

Fe 2+ , cu 2+ , Mg 2+ , k + , CEC, Ex. Acidity, extractable Mn 2+ , organic carbon (g/kg), organic matter (g/kg), and available phosphorus were extremely variable soil properties. The available moisture of soil was very low thus water holding capacity (WHC) and wilting point (WP) of the soil was very l...

A ten kilogram of soil was packed in the pots with an initial bulk density of 1.05 Mg m-3, then it were compressed to1.57, 1.72, 1.88, 2.04, and 2.42 Mg m-3. The research was conducted in a completely randomized design with three replications. Groundnut seeds were sown in pots and the plant growth data were collected in a 2-week interval while force and energy of harvesting and soil loss due to groundnut harvesting were determined at 12 weeks after sowing. Data were analyzed using ANOVA and Fishers LSD at P= 0.05. Soil compacted to1.88 Mgm-3 produced more taller plant, more higher number of leaves and branches than control. Soil compaction significantly reduced the number of pods, roots, and fresh root weight compared to control. Bulk density (2.04 Mgm-3) required a significantly higher force (42.47 N...

The result of the analysis and the variability grouping put colour value in AP and B 1 as least variable. Stoniness (AP) and structure (AP and B 1) were moderately variable properties. Colour (AP, B 1 B 2 and B 3), structure (B 2 and B 3), stoniness (B 1 , B 2 and B 3), concretion (AP B 1 , B 2 and B 3) and boundary forms (B 1 , B 2 andB 3) have extremely variable properties. pH (H 2 O and KCl), Na + base saturation were least to variable. Fe 2+ , cu 2+ , Mg 2+ , k + , CEC, Ex. Acidity, extractable Mn 2+ , organic carbon (g/kg), organic matter (g/kg), and available phosphorus were extremely variable soil properties. The available moisture of soil was very low thus water holding capacity (WHC) and wilting point (WP) of the soil was very low. .The gravel content of the land was high at the surface and reduced down the slope... Bulk density parameter of the land was very high at the surface. The land was very low in plant nutrients, this result show that the soil of the cashew plantation is highly variable and that management techniques that would be flexible enough to carter for the variation noticed should be adopted, such as organic fertilizer application.
