Abstract Low soil fertility is a major problem limiting peri-urban vegetable production in the Kumasi metropolis. This study was conducted to assess the effects of poultry litter biochar (PLB) and NPK fertilizer application on soil chemical properties and the yield of cabbage. Twelve treatments (control, 100% NPK, 50% NPK, 2.5 t ha−1 PLB, 2.5 t ha−1 PLB + 50% NPK, 2.5 t ha−1 PLB + 100% NPK, 5 t ha−1 PLB, 5 t ha−1 PLB + 50% NPK, 5 t ha−1 PLB + 100% NPK, 7.5 t ha−1 PLB, 7.5 t ha−1 PLB + 50% NPK, and 7.5 t ha−1 PLB + 100% NPK) were evaluated under field conditions in a randomized block design with three replications. Combined application of PLB and NPK fertilizer improved the soil chemical properties, growth, and yield of cabbage relative to the control and sole PLB treatments. Application of 5 t ha−1 PLB + 50% NPK increased the soil pH, soil organic carbon, available phosphorus, and cation exchange capacity by 26.6, 41.4, 296, and 78.7%, respectively, relative to the control. Moreover, 5 t ha−1 PLB + 50% NPK increased the cabbage yield by 73% compared with the control. This study concludes that PLB and NPK fertilizers can be applied to improve the soil chemical properties and yield of cabbage.

Agricultural utilization of bioslurry plays a critical role in soil conditioning and hence crop production. It also reduces greenhouse gas emissions thus mitigating climate change. Although the effect of bioslurry on growth and yields is well researched, that of different biodigester types is under-researched. Therefore, a study was carried out in Waruhiu Agricultural Training Centre, Githunguri sub-county, Kiambu county in Kenya, to investigate the effect of bioslurry from flexi and dome biodigesters on soil chemical properties, maize growth, yield and grain quality. Treatments were laid out in a Randomized Complete Block Design (RCBD) and replicated three times. The treatments were bioslurry from both Fixed Dome and Flexi biodigesters, applied separately at a rate of 400mls per hill as basal and top dress fertilizer. Planting was done during the 2019 short and 2020 long rains, using Duma 43 maize variety. The agronomic (germination percentage, number of leaves, leaf width, leaf length, plant height) and productivity data (stalk, stovers, grain yields and grain quality) were subjected to analysis of variance (ANOVA) through Proc general linear model (GLM) procedures. Mean separation was done using least square means (LS-Means). Results showed an increase in soil pH, total N and OC, exchangeable P, K, Mn and Na in both biodigester types. Total N and OC were higher in Dome treated soils by 38.89% and 37.00%, while in Flexi, it was 16.67% and 16.00% respectively. Exchangeable P and K was higher in Flexi treated soils with a 38.57% and 50.00% increase while in Dome it 37.86% and 47.22% respectively. Magnesium and Zn decreased after treatment by 34.30% and 22.59% in Dome while Flexi had 33.23% and 31.79% increase. Exchangeable Fe and acidity decreased in Dome but increased in Flexi treated soils. No statistical differences were observed on growth and yield parameters but Dome registered higher grain yields by 9.4% and 6.3% for short and long rains respectively. Flexi treated soils registered higher values in most grain nutrient content such as K, Fe, Cu, Mn and Zn in short rains and P, Ca, Fe, Cu, Mn and Zn in the long rains. Bioslurry from both biodigester types variably increased the evaluated soil chemical properties but decreased Mg and Zn. Despite the numerical differences noted between bioslurry from both biodigester types on maize growth and yield, there was no significant difference (p≤.05). However, Dome bioslurry increased N, OC and maize grain yield more while exchangeable P and K and most of the grain nutrient content were higher in Flexi treated soils. Therefore, bioslurry from either biodigester type can be used in enhancing soil conditions, growth, yield and quality of maize. However, a long-term experiment is required validate the findings.

Cucumber yield in Nigeria is limited by low soil fertility. Therefore, field fertility and vine care experiments that have ability to moderate yield were conducted in the year 2015 cropping seasons. The experiment was located on farmer’s field at Abeokuta, Ogun State, Southwestern Nigeria to study the effects of NPK fertilizer and vine care on soil chemical properties, leaf nutrient content, growth and yield of cucumber (Cucumis sativus L.). It was a 4 x 3 factorial experiment arranged in a Randomized Complete Block Design (RCBD) with three replicates. Four levels of NPK nutrient formulations (control, NPK15-15-15, NPK 20-10-10 and NPKMg 12-12-17-2) and three vine care types (unstaked, staked and trellised) were applied. Pre-experiment soil samples and soils from each plot at the end of the experiment were collected for soil chemical analysis. Leaf nutrient contents were determined. Plant growth and yield data were measured. Data collected were subjected to statistical analysis and the interaction between factors combined separated. NPK fertilizers significantly (P ≤ 0.05) increased soil N, P, K, Ca, Mg and leaf P, K, Ca and Mg concentrations, Cucumber fruit yield was increased by NPKMg 12-12-17-2 (90.5%), NPK 15-15-15 (60.4%) and NPK 20-10-10 (30.0%) compared with control. Application of vine care enhanced performance of cucumber, fruit yield was increased by trellised (34.0%) and staked (17.3%) compared with control. Combined application of NPKMg 12-12-17-2 and trellising was found most suitable for cucumber production.

Towards a more sustainable soil management through recycling of readily available weeds in Akure, Nigeria, different rates of Tithonia diversifolia (tithonia) were compared on a field trial to evaluate its effect on soil properties. The experiment was sited at two locations in South gate of the Federal University of Technology, Akure. Prior to the field establishment, a composite soil sample was collected and analyzed for physico-chemical properties. The sites were cleared and tilled. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates. The treatments consisted of three levels of tithonia application which are 0, 3 and 6 t ha-1. Each experimental unit size was 2 m x 2 m with 1 m alleyway. Maize (Zea mays L. var.TZB-SR) seeds were sown at a spacing of 75 cm by 25 cm and 10 were randomly sampled per plot for growth and yield parameters. Data were collected on maize yield and soil physical and chemical properties after harvest to ascertain sustainability of the mulch material after cropping. Application of tithonia mulch improved growth, and yield indices of maize as well as soil physical and chemical properties. The contents of soil total N, exchangeable cations, , CEC, Organic matter content, total porosity, moisture content and infiltration rate were found to significantly (p>0.05)  increase in treatments with tithonia mulch. The best result was from the application rate 6 tha-1 because it improved and left the soil conserved after harvesting maize. Similar trends were observed at the two sites despite variation in inherent soil properties.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

The soil physical and chemical properties of four densities (A:2500/hm2,B:3300/hm2,C:4400/hm2,D:6600/hm2) of hybrid Larch plantations, Larix olgensis plantation(E) and Quercus mandsurica forest(F) were studied in Jiangshanjiao forest farm of Heilongjiang province of China. Soil bulk density, soil porosity, total N, total P, available N and available P were affected significantly by plantation density in hybrid Larch plantations. The lowest surface soil bulk density was in density 2500/hm2. Soil porosity of density 2500/hm2and 3300/hm2was bigger than that of density 4400/hm2and density 6600/hm2. Total N, total P and available N of density 4400/hm2and 3300/hm2were higher than that of density 6600/hm2and density 2500/hm2. Total N, total P, available N and available P of hybrid Larch plantations were not lower than that of Larix olgensis plantation. The results of the soil physical and chemical properties under different densities of hybrid Larch plantations and different types of forest seems to confirm that hybrid Larch plantation did not decreased the soil fertility, and the hybrid Larch plantation with densities of 3300/hm2and 4400/hm2could be conductive to improving the soil quality. The results would provide the theories basis for manage the hybrid Larch plantations.

Suminarti et al, 2018. Effect of Source and Dosage of Organic Materials on Changes in Soil Chemical Properties, Growth and Yield of Sorghum Plants (Sorghum bicolor L.Moench) var. KD4 in Dry Land Jatikerto, Malang. JLSO 7(2): Agricultural extensification is the right step to anticipate conditions of food insecurity. This refers to two reasons, namely (1) proliferation of land conversion activities, and (2) sorghum is a carbohydrate-producing plant that is quite tolerant when planted on dry land. The objective of this study was to obtain information about the sources and doses of organic matter that are appropriate to changes in soil chemical properties, growth and yield of sorghum plants, and has been carried out in the dry land of Jatikerto, Malang. A split plot designs with three replications were used in this study, sources of organic material (blothong, UB compost and cow dung) as the main plot, and doses of organic matter (125%, 100% and 75%) as a subplot. Soil analysis was carried out 3 times, i.e. before planting, after application of organic matter and at harvest. The agronomic observations were carried out destructively at 80 days after planting (DAP) including the components of growth (root dry weight, leaf area, and total dry weight of the plant) and harvest at the age of 90 DAP.F test at 5% level was used to test the effect of treatment, while the difference between treatments was based on LSD level of 5%.The results showed that there was a significant interaction between the source and dosage of organic matter on the leaf area and total dry weight, the highest yield was obtained in blothong at various doses. Higher yields of seeds per hectare were also found in blotong: 1.76 tons ha-1, and 1.73 tons ha-1 on 125% doses of organic matter. Blotong application is able to provide elements of N, P and K soil respectively 18.3%, 85.68% and 8.42% for plant.

Aim: A pot experiment was carried out to determine the effect of sawdust ash and lime (Ca(OH)2) on soil characteristics and yield of sunflower in acidic soil of southeastern Nigeria. Study Design: The experiment was laid out in split-plot design, using sawdust ash (0, 1, 2, 3, 4 t ha-1) as the sub plot and lime (0, 0.5, 1.0, 1.5 t ha-1) as the main plot. Place and Duration of Study: Study was conducted outdoors at Michael Okpara University of Agriculture Umudike, Nigeria, during the 2010 planting season. Materials and Methods: Treatment combinations were applied to the 60 buckets containing soil, mixed thoroughly and watered adequately. After 1 week of treatment application, two sunflower seeds were planted and later thinned to one seedling per bucket. Plant growth and yield data were collected. Pre planting and post-harvest soil samples were collected and analyzed for soil properties. Results: Results showed that with the exception of organic carbon there was significant effect of treatments on all soil chemical properties. Lime and sawdust ash (SDA) as single and combined treatments significantly increased total nitrogen (P=0.05), available phosphorus (P<0.010), and base saturation (P<0.012). The interaction between SDA and lime significantly (P=0.05) increased total exchangeable bases and effective cation exchange capacity, while soil pH was significantly increased (P=0.05) by single applications. The increases in soil chemical properties led to significant positive response of the sunflower. With the exception of number of leaves, other plant parameters (Plant height, stem diameter, head weight, 50 seed weight, head diameter) had significant increases for sawdust ash alone at P=0.05. Correlation studies showed positive significant relationship between soil pH and sunflower yield. Conclusion: The study showed that sunflower performed best at the combination of 3 tha-1 SDA and 1.5 t ha-1 lime producing a mean head weight of 45.4 g.

The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.
