African Star Apple

African Star Apple (Chrysophyllum albidum) classified as a forest food tree with economic potentials requires domestication attention for improved productivity. A study conducted in Abeokuta, Nigeria in 2017 using one year old C. albidum seedlings determined the plant’s growth responses when cultivated using different growth medium and soil amendment methods. The 3 x 9 factorial experiment was arranged in a Completely Randomized Design (CRD) at three replications. Three textural soil types (sandy, loamy and clayey soils) were evaluated using nine soil amendment methods (5, 10, 15t/ha poultry manure (PM) and 150, 250 and 500kg/ha NPK, and integrated amendment methods using 5t/ha PM+150kg/ha NPK and 10t/ha PM+150kg/ha NPK), and the un-amended plot as control. The results showed that plants in loamy and clayey soils had more leaves compared to those in sandy soil only at 74WAS. C. albidum had most numerous leaves with 150 kg/ha, taller plant and wider canopy with 250 kg/ha, and thicker girth with all NPK rates compared to control, manure rates and integrated fertilizers. The plants with loamy soil had highest CPC, Ash C, FC, starch and sugar. Plants with inorganic fertilizers and integrated fertilizers had higher FW and DW compared to manure rates. The 5 t/ha manure rate and the 250 kg/ha NPK produced plants with high sugar content and were lowest in starch content compared to other applied rates. In conclusion, C. albidum from juvenile to vegetative stage with proper management can be grown on the different soil types while the 150 kg/ha NPK fertilizer rate appeared as optimum for the plant growth.

Fact Sheet

Animal manures have been used as natural crop fertilizers for centuries. Because of poultry manure’s high nitrogen content, it has long been recognized as one of the most desirable manures. Besides fertilizing crops, manures also supply other essential plant nutrients and serve as a soil amendment by adding organic matter, which helps improve the soil’s moisture and nutrient retention. Organic matter persistence will vary with temperature, drainage, rainfall, and other environmental factors. This 2-page fact sheet was written by Michael A. Davis, D.R. Sloan, Gerald Kidder, and R.D.

Root Waving

Experimental studies show that plant root morphologies can vary widely from straight gravity-aligned primary roots to fractal-like root architectures. However, the opaqueness of soil makes it difficult to observe how environmental factors modulate these patterns. Here, we combine a transparent hydrogel growth medium with a custom built 3D laser scanner to directly image the morphology of Medicago truncatula primary roots. In our experiments, root growth is obstructed by an inclined plane in the growth medium. As the tilt of this rigid barrier is varied, we find Medicago transitions between randomly directed root coiling, sinusoidal root waving, and normal gravity-aligned morphologies. Although these root phenotypes appear morphologically distinct, our analysis demonstrates the divisions are less well defined, and instead, can be viewed as a 2D biased random walk that seeks the path of steepest decent along the inclined plane. Features of this growth response are remarkably similar to the widely known run-and-tumble chemotactic behavior of Escherichia coli bacteria, where biased random walks are used as optimal strategies for nutrient uptake.

Research to determine the ripening time of the fruit is the scientific basis for better harvesting and preservation. Physiological and biochemical methods were used to analyze the changes of some indicators according to the growth and development of banana fruit grown in Thanh Liet commune, Thanh Tri district, Hanoi from the time of its formation until the fruit ripening. The results showed that the banana reached the maximum size at 16 weeks old, at this time the peel was yellow due to the decrease in chlorophyll and increased carotenoid content. The content of vitamin C and total organic acid content reached their maximum when the fruit at 12 weeks old, then decreased gradually. Starch content increased to 14 weeks old, then decreased. Reduced sugar content increased gradually to 16 weeks old and then decreased. Protein content decreased gradually from fruit formation until fruit ripening, lipid content increased gradually to 15 weeks old, then decreased. Through the research process, we have determined that the physiological ripe time of banana fruit was 16 weeks old, this is the time when the fruit stops growing and accumulates many nutrients.

Persian lime is economically important for Mexico. However, the disease known as Huanglongbing (HLB) causes chlorosis symptoms in the foliage that affect the growth and decreases the yield of the trees. The expression of chlorosis symptoms is associated with starch accumulation and inhibition of antioxidant activity. The objective of the present work was to determine the effect of the application of three resistance elicitors on the expression of three antioxidant genes and on starch and chlorophyll content in Persian lime trees with HLB. Salicylic acid (SA), jasmonic acid (JA) or gamma-aminobutyric acid (GABA) were applied every eight days for nine weeks using a completely randomized design and a one-way ANOVA was performed for the analysis. Expression of APX, CAT and SOD genes was quantified at week nine at four different times. Starch and total chlorophyll content was estimated every three weeks by spectrophotometric methods. The application of the elicitors significantly increased the expression of the three genes, with SA and GABA generating the greatest increase at different times of application. No difference was found in starch and total chlorophyll content at most of the times evaluated. The use of resistance elicitors is promising in the management of HLB in plots already infected, seeking to extend the productive life of the orchards and thus counteract the economic losses caused by HLB.

Wheat pollard is a waste of the wheat industry and many contain non starch polisacharida (NSP) that interfere with the chicken digestive tract. NSP in wheat pollard can be removed by heating, so it can be used by microbes in the digestive tract of poultry. Utilization of NSP by microbes will result in short chain fatty acids (SCFA), namely acetic acid, propionate and butyrate which have a positive effect on the digestive tract of poultry. The purpose of this study is to examine changes in levels of rafinose, glucose, mannose, arabinose and sucrose in wheat pollard into a source of functional feed for poultry. The benefit of research is to know the technique / manufacture of functional feed material from wheat pollard. The material used in the research is wheat pollard and aquades by using autoclave tool. The design used was a complete randomized design of 2x3 factorial pattern with 3 replications. The first factor is the duration of steam 30 and 60 minutes while the second factor is the addition of water (0, 30 and 60%). The results showed that the addition of water and the duration of different steam strongly influenced (p <0.001) and had interactions on rafinose, mannose, arabinose, sucrose and glucose parameters. The mean of water addition factor increased rafinose level from 1.11+0.03% to 29+0.02% while steam duration decreased raffinose content from 1.99+0.01% to 1.90+0.04%. Glucose levels increased in water addition factor and steam duration from 0.25+0.01% to 1.06+0.12% and 0.54+0.03% to 0.63+0.07%. The mean of water addition factor decreased the mannose level from 0.19+0.01% to 0.06+0.02% and the steam duration increased the manosa level from 0.09+0.01% to 0.15+0.01%. Levels of arabinose increased in water addition factor and steam duration from 0.30+0.03% to 0.98+0.01% and 0.54+0.02% to 0.70+0.04%. The average water addition decreased the sucrose content from 1.80+0.09% to 1.55+0.04% and the steam duration increased the sucrose content from 1.48+0.04% to 1.72+0.03%. The research conclusions that the steam treatment and the addition of water greatly affect the changes of rafinose, glucose, mannose, arabinose and sucrose in wheat pollard and potentially as functional feed. Recommendations that can be given by researchers is the source of feed ingredients that have high starch content should be processed before it is given to poultry so it has a functional value and improve the digestibility of the feed material.

During the storage period, sweetpotato’s nutrition content will potentially deteriorate, particularly in moisture and starch content. This will eventually affect the quality of sweetpotato. The shelf life of sweetpotato is marked by the spoilage in the form of quality deterioration and some noticeable signs of diseases, most of which are induced by microorganism. This study aimed to study the best technology to evaluate quality change, diseases and shelf life of sweetpotato. The experimental design used was completely randomized design of 4 factors by using various storage ways, i.e. underground storage with sand-straw (P1), underground storage with plastic-straw (P2), inside a wooden box with sprinkling of sawdust (P3), and inside a warehouse with a tarpoulin mat (P4). The results showed that the storage treatments influenced the temperature and RH in a storage room with the values as follows: 8.72 ° C and 78.55% (P1), 28.85 C and 78.51% (P2), 29.54 and 73.15 ° C % (P3), and 29.61 ° C and 68.07% (P4). Moisture and starch contents in sweet potato significantly decreased until the end of storage in which the lowest levels were found in P4 treatment, 58.96 % water content and 11.35 % starch. Postharvest diseases found in sweet potato during research were Fusarium rot (P4) and java black rot (P2). In conclusion, underground storage with sand-straw (P1) was selected as the best method to minimize rate of decreasing moisture and starch contents in sweetpotato with the longest storage period estimated of 35 days.</p>
