Problematic Soil

Beach ridges interspersed with swales (BRIS) soil is identified as one of Malaysia's problematic soil since this type of soil contains a plethora portion of sand texture that contributes to water and nutrient leaching causes infertile soil. A polybag trial was conducted to evaluate the effects of wood vinegar and rice husk biochar on soil properties and growth performances of immature kenaf. The plant was arranged in a completely randomised design with four treatments and three replications. The factors taken for the experiment were four different media compositions, i.e., T1(control), T2(BRIS soil amended with wood vinegar, WV), T3(BRIS soil amended with rice husk biochar, RHB) and T4(BRIS soil amended with wood vinegar and rice husk biochar, WV+RHB). Rice husk biochar and a combination of wood vinegar with rice husk biochar significantly improved soil properties in terms of soil moisture content, organic matter, water retention and soil porosity, as well as significantly increased the kenaf stem diameter. However, there was no significant difference in plant height, number of leaves, leaves area and chlorophyll content on different treatments medium. In conclusion, the application of rice husk biochar and wood vinegar in this study enhanced BRIS soil properties and showed a positive effect on the growth of immature kenaf.

Two Phases

Vertical garden system has the potential to increase vegetable production in the urban areas in Malaysia. This research designed and developed a compact and smart vertical garden system for the urban agriculture. It also analysed the growth performances of lettuce in the smart vertical garden system which involved two phases; the development of vertical garden system and the monitoring system for nutrient solution. The growth performances of different stacks of lettuce (Lactuca sativa) in the vertical garden system were observed and compared against the commercialised conventional hydroponic system. The growth performances of lettuce in the vertical garden system showed that the most bottom stack (stack 5) of lettuce achieved the maximum level of lettuce height, and had the highest number of leaves and leaves width. Nevertheless, from the overall ANOVA results, at different levels of the stacks of lettuce, only lettuce height was observed as having a significant difference (P < 0.0001) while no significant difference was found in the number of leaves (P = 0.0002) and leaves width (P = 0.0046). The growth development varied due to different amounts of water and light exposure. On the other hand, no significant difference was found when comparing between the vertical garden system and the commercialised conventional hydroponic system (lettuce height, P = 0.4997; number of leaves, P = 0.5325; and leaves width, P = 0.5231). In short, the smart vertical garden system can give the same performance as the commercial conventional hydroponic system.

The aim of this study was to investigate the effect of mycorrhiza application on the vegetative development of blackberry cuttings grown under different irrigation regimens. The research was conducted between March-June 2019 in Akdeniz University, Faculty of Agriculture, Research and Application Area. Glomus etunicatium, obtained from Çukurova University Soil and Plant Nutrition Department was used as mycorrhizal fungal material and four different irrigation levels (40%, 60%, 80%, 100%) were applied in the experiment. In order to investigate the effects of the applications on the morphological properties of blackberry cuttings, shoot diameter, plant length, number of leaves and relationship of these variables with each other and flowering dates were determined. When the results were evaluated, it was determined that mycorrhiza application had a positive effect on the vegetative development of the plants. Significant differences were determined between the effects of different irrigation levels on the morphological development of plants. The highest average shoot length (62.08 cm), stem diameter (8.37 mm) and number of leaves (16.28 number/plant) were obtained from the S100 application, where full irrigations were performed. However, there was no statistically significant difference between S80 and S100 subjects in terms of shoot length and stem diameter, and S60, S80 and S100 subjects in terms of number of leaves.

The study was conducted to assess the effects of traditional tillage practices namely No-till, Ridge-till and Mound-till, on cassava growth parameters and soil physico-chemical properties. It was a factorial experiment laid out in a randomised complete block design replicated 3-times. The factors were the 3-tillage methods and cassava plant as a test crop. Data collected on soil properties include the particle size distribution, soil bulk density, soil water content, hydraulic conductivity, soil pH, soil organic carbon, total nitrogen, available phosphorus and exchangeable bases, while data collected on plant growth and yield indices include; plant height, stem girth, number of leaves, number of tubers, tuber length and weight of tubers. The data were collected at 2, 4, 6, 8, 10 and 12 months but cumulated at 12 months after planting. The data were subjected to analysis of variance and relationship between cassava tuber yield and some soil properties measured. Results of the study showed that there was no significant difference between Ridge and Mound-till. The Ridge-till and Mound-till systems significantly influenced plant height, stem girth, number of leaves, tuber weight and total yield of cassava than No-till system, hence were recommended of increased yield of cassava in the study area.

Changes In Soil Properties

Biochar, a pyrogenic carbon, has been receiving incremental attention for potential contribution to soil health, agricultural productivity enhancement while mitigating climate change by sequestering carbon and reducing greenhouse gas (GHG) emissions. However, it is not well-known to us how far rice husk biochar (RHB) application rates could increase phosphorus (P) bioavailability and plant performance when co-applied with P and lime. Here, we present data of a pot experiment consisting of eleven treatments to evaluate RHB, lime, and phosphorus effect on soil phosphorus availability, CO2 emission, nutrient uptake, and yield performance of maize. Co-application of RHB (10 and 15 t ha−1) and lime (100% and 75%) was made with different rates of P (100%, 75%, and 50%). Our result revealed that, at harvest, the combined application of RHB, lime, and phosphorus fertilizer significantly increased soil pH, P availability and decreased Al and Fe toxicity relative to the control while increasing maize yield. The maximum soil pH increased by 36.75%, the highest available P increased by 158.75%, whilst, the exchangeable Al content reduced by 96.84% compared to the control treatment. However, the difference in biomass production and yield among different lime, RHB, and P were minimal, with the largest grain yield (15.50 t ha−1) was recorded in the T6 treatments (75% lime + 10 t ha−1 RHB + 100% Triple superphosphate). The increment in biomass and grain yield could have occurred due to lime and RHB mediated changes in soil properties, including enhancement of soil pH, availability of P, and other nutrients. This increased availability then increased nutrient uptake and biomass production. Our results suggest that the combined application of lime and RHB could bring favorable changes in soil properties while sacrificing some carbon from soils.

<em>Seedling is an important process in preparing cocoa plant material. The growing medium must have sufficient nutrition and physical properties to enable cocoa seeds to grow well. Arbuscular mycorrhizae fungi (AMF) and biological charcoal (biochar) added into growing media were expected to increase the growth of cocoa seeds. The study aimed to determine the effect of AMF and biological charcoal on the growth of cocoa seeds. The randomized complete block design (RBD) in factorial 2 factors with three replications was used in this study. The first factor was AMF application consisted of two levels, namely: M0 = without AMF and M1 = application of 10 g/seedling AMF (100 spores/seedling). The second factor was the biochar application consisted of 5 factors namely: B0 = no biochar, B1 = 2% rice husk biochar, B2 = 4% rice husk biochar, B3 = 2% albizia wood biochar, and B4 = 4% albizia wood biochar. The variables observed were the height of seedling, number of leaves and stem diameter at 3, 4, 5 and 6 month after planting (MAP), leaf chlorophyll content, weight of dry cocoa seedling, and nutrient content in seedling media. The result showed that the application of AMF significantly affected the height of seedling at 3, 4, 5 and 6 MAP. While the application of biochar significantly affected the height and number of leaves of cacao seedlings.</em>

Rice Husk Biochar

This investigation was conducted to evaluate the outcome of rice husk biochar on growth performance of moringa. The study was carried-out in a greenhouse for 52 days. Different rates of rice husk biochar (150 to 350 g) was mixed with 500 g of soil. A Randomized Complete Block Design (RCBD) with 3 treatments (each of which was replicated 3 times) was used, giving a total of 12 experimental units. Plant height, stem diameter and number of leaves were assessed for each treatment. Results indicate that rice husk biochar (150 g, 250 g and 350 g) significantly increased the stem diameter of moringa as compared to that of the control 52 days after in the greenhouse. An increase in the number of leaves were observed at 150 g rice husk biochar after 40 days compared to the control. There were significant differences between treatments effects on all the parameters. Different rates of biochar certainly could constitute vital use of fertilizer to improve growth moringa in the nursery.
