The objective of this experiment was to evaluate the cultivation, production and quality systems of Asystasia gangetica T. Anderson as forage in palm oil plantations. This research was arranged in a factorial randomized block design with 2 factors, i.e. palm plantation ages (6 and 8 years old) and different plant spacing (10x10 cm, 25x25cm, and 40x40cm). Variables observed were plant height, number of leaves, number of primary and secondary branches, leaf length and width, biomass production, and nutrient contents. Spacing was significantly affected (p<0.05) on increasing height plant, number of primary and secondary branches, number of leaves, leaf width and length, and biomass production. The spacing also has a significant effect (p<0.05) on nutrient content such as dry matter and crude fiber. The heighest plants average at plant spacing of 10x10 cm was 66.19 cm, the best number of primary and secondary branches at spacing of 25x25 cm were 2 and 10 branches, the average number of the best number of leaves at spacing of 25x25 cm was 80 leaflets, leaveslength and width at spacing of 10x10 cm were 12.49 and 4.29 cm, while the best biomass production at spacing of 10x10 cm was 2766 g. The research concluded that in order to obtain high crop production, the best plant spacing was 10x10 cm under 6 years old of palm plantation, whereas the best nutrient quality was on 25x25 cm spacing.

Soilless substrates enhance growing environment, nutrient content, and water quality in the growing medium. The objective of this study was to assess the influence of substrate particle size on growth and flower quality (flower number and length per plant) of two asiatic hybrid lily (Lilium ×elegans) cultivars Fangio and Ercolano. Plants were grown in 12-L pot under greenhouse conditions. Five grades of particle-size substrate, consisting of granulated volcanic material (tuff) were used as treatments. These sizes were 0 to 2, 0 to 4, 0 to 8, 2 to 4, and 4 to 8 mm. Fertigation was applied daily. Plant morphology, physiology, and flower quality were determined during flowering stage. Treatments of 2 to 4- and 4 to 8-mm tuff had lower water holding capacity (WHC), bulk density, electrical conductivity (EC), and pH compared with 0 to 2- and 0 to 4-mm tuff. In addition, plant height, leaf area, and flower quality of ‘Fangio’ were higher compared with ‘Ercolano’. Chlorophyll content and fluorescence were similar among all treatments. Leaf fresh weight, leaf area, shoot dry weight, root dry weight, and flower quality were higher in sizes of 0 to 4-, 2 to 4-, and 4 to 8-mm than 0 to 2-mm tuff, especially those from ‘Fangio’. The 0 to 4-mm substrate had an optimal and consistent flower quality results in both cultivars when compared with other tuff sizes. Overall, the results presented here suggest that using 0 to 4-mm tuff substrate holds promise for improving growth and flower quality of asiatic hybrid lily grown under soilless culture.

The broad objective of this work is to improve the nutrient content of cassava flour by inclusion of cowpeas seed flour and cassava leaf powder to assess the effects of the cowpeas flour and cassava leaf powder inclusion on the nutrient quality and acceptability of the flour. Cassava tuber flour was fortified with cowpeas flour and from cassava leaves at 20% and 30% of dry weight. Standard methods were used for the determination of parameter such as protein and carbohydrates. All samples were analysed for potassium, phosphorus, calcium, magnesium, iron, and cyanide. Unfortified cassava had significantly lower (P<0.05) values (protein: 0.942%, P: 0.093%, K: 0.749 Mg: 0.052%, Fe: 5.008ppm) than fortification with both cowpeas flour and cassava leaf flour. Fortification with cowpeas flour did not significantly (P>0.05) change the Ca content however they were significant (P<0.05) increases cassava leaf flour. Cyanide content increased significantly for Treatment LF20 and LF30 but remained unchanged for Treatment CW20 and CW30. Both cowpeas and cassava leaves had significantly (P<0.05) lower carbohydrate content than cassava tuber flour. Both cowpeas and cassava leaves are excellent for fortification but cassava leaves have to be used with additional pre-treatments to reduce the cyanide content in them. Organoleptic qualities analysed indicate high acceptability of fortification of cassava tuber flour with cowpeas flour.

The nutrient content of representative plant parts and biomass production in the Nakivubo wetland, correlation of these with the wastewater flow patterns and determination of nutrient uptake, storage and biomass production of Cyperus papyrus (papyrus) and Miscanthidium violaceum was studied. On average papyrus vegetation under the influence of wastewater had higher nutrient content in the above ground biomass (1.6% N and 0.23% P on dry weight basis) than those not affected (0.98% N and 0.18% P). The biomass varied between 3,529-5,844 g/m2 and 883-1,156 g/m2 in the two respective sites. The juvenile plants of papyrus and Miscanthidium had higher concentrations of P and N in their organs compared to the mature ones. Considering the nutrients stored by the dominant vegetation and the current flow patterns of wastewater in the Nakivubo wetland, harvesting of the above ground biomass once a year, would remove 7.7% of the N input and 15.8% of the P input of the annual total load entering the wetland. However, if the wetland is bio-manipulated and the wastewater flow distributed over the whole wetland, up to 70% nitrogen and 76% phosphorus would be removed by harvesting above ground papyrus biomass.

Pruning Regime

Gliricidia sepium is considered one of the commonly used multipurpose legume shade trees in Ghana. Different pruning regimes affect the nutrient content as the amount of biomass produced by many multipurpose trees. In this study, the aboveground biomass (both fresh and dry matter) production and nitrogen content in Gliricidia sepium under different pruning regimes (4, 8 and 12 weeks) was studied. The study was carried out in the demonstration farm of Department of Agroforestry in the Faculty of Renewable Natural Resources-KNUST. A total of nine (9) Gliricidia trees were selected. The pruning frequencies were assigned to the selected trees, after an initial pruning of 1.2m from the ground. The data collected include; new fresh weight, dry weight and nitrogen content at the various pruning time. Also, the amount of nitrogen (N) in the new biomass was estimated at each pruning time. The result shows that the aboveground biomass production increased from 4 weeks to 12 weeks regime. Overall nitrogen concentration increased from 2.61% to 3.58% upon reducing the pruning frequency from 4 to 12 weeks, and total nitrogen content was much higher in 12 weeks (36.01g) than in the other pruning frequencies, due to biomass production been larger. In conclusion, the study highlights the potential of Gliricidia biomass as a source of N and green manure for both agricultural and agroforestry purposes. Hence pruning regime of Gliricidia should be considered in managing it for nutrient and manure purposes.

In this study, we examined a Chlorella vulgaris-based system as a potential solution to change liquid waste, such as blackwater, into valuable products for agriculture while protecting waters from pollution without technical demanding pre-treatment. To evaluate the possibility of nutrient removal and biomass production from raw blackwater, four blackwater dilutions were tested at lab-scale: 50%, 30%, 20%, and 10%. The results showed that even the less diluted raw blackwater was a suitable growth medium for microalgae C. vulgaris. As expected, the optimum conditions were observed in 10% blackwater with the highest growth rate (0.265 d−1) and a nutrient removal efficiency of 99.6% for ammonium and 33.7% for phosphate. However, the highest biomass productivity (5.581 mg chlorophyll-a L−1 d−1) and total biomass (332.82 mg dry weight L−1) were achieved in 50% blackwater together with the highest chemical oxygen demand removal (81%) as a result of the highest nutrient content and thus prolonged growth phase. The results suggested that the dilution factor of 0.5 followed by microalgae cultivation with a hydraulic retention time of 14 days could offer the highest biomass production for the potential use in agriculture and, in parallel, a way to treat raw blackwater from source-separation sanitation systems.

Container seedling production systems for forest tree nurseries are challenged by the need for judicious water consumption. Subirrigation systems may provide an alternative to overhead systems by mitigating water use, yet remain relatively untested for propagation of forest tree seedlings. We evaluated effects of overhead versus subirrigation under varying media (40:60, 60:40, and 80:20 peat:perlite) and fertilization (0 or 1.2 g nitrogen/plant) regimes on nursery development and first-year field performance of northern red oak (Quercus rubra L.) seedlings. Fertilization increased aboveground biomass production and nutrient content, but decreased root dry weight. Relative to overhead-irrigated seedlings, subirrigation increased red oak seedling aboveground biomass production as well as above- and belowground nitrogen content under fertilized conditions. Media had no effect on plant response. Subirrigation increased electrical conductivity (5 dS·m−1 greater) and decreased pH in the upper media zone (0 to 5 cm from top), whereas the opposite effect was found in the lower zone. Nursery fertilization was associated with reduced field survival and growth, which may have been the result of transplant stress resulting from higher shoot:root. Subirrigated seedlings had greater field diameter growth. Our results suggest that subirrigation could serve as a viable alternative to overhead systems in container propagation of hardwood seedlings.

       Forage is a major requirement in increasing ruminant livestock production. Kuantan Singingi Regency is a district that has quite a lot of grasslands whose production and quality of forage are unknown, so this study aims to determine the production and nutritional content of forages in Kuantan Singingi Regency. This research consisted of three stages, survey (field observation and location determination), forage sampling, and nutrient quality analysis. Forage samples were taken in 4 sub-districts, namely the Districts of Central Kuantan, Sentajo Raya, Gunung Toar and Kuantan Mudik. 5 locations were taken for each sub-district, 4 points for each location were taken. The tools used for forage sampling consisted of a 0.5 x 0.5 m2 quadrant, grass shears, sickle, plastic bags of size 10 and size 2 kg, sacks, plastic ropes, and stationery. The analysis of nutrient quality using forage samples in 4 districts using proximate analysis. Forage production data and forage nutrient content were statistically analyzed using analysis of variance (ANOVA). The results showed that there were differences in production and nutrient content in each sub-district P<0.05. Fresh biomass production showed a significant effect of P<0.05. Fresh forage production ranged from 111.67±16.45 Kg FW/ha/day, while dry forage production ranged from 23.80±5.29 Kg to 187.04±67.35 Kg. The conclusion of this study is that the production and nutritional content of forage in Kuantan Singingi Regency is relatively low, the production of DW/ha/day is 23.80-40.35 Kg, and the CP ranges from 7.85-10.55% DW.

Fertilizing Effect

Despite phosphorus resources on Earth being limited, over fertilization in many agricultural situations causes significant resource consumption. Phosphorus-recycling within agricultural production can reduce global dilution into the environment and is thus essential to secure sustainable future supply. This study investigated the fertilization efficacy of phosphorus fertilizers recycled from biogas digestates in maize shoots grown under controlled greenhouse conditions, in two soils, in a pot experiment. Variables investigated were plant-available phosphorus in soil, plant biomass production, and concentration of phosphorus, calcium, and magnesium in shoots. Soils were treated with three different fertilizer fractions, separated from biogas digestates, at equivalent phosphorus concentrations, using different combinations and application techniques, isolated or in combination, and compared to triple superphosphate (TSP) as a reference. One of the fractions (P-Salt) had effects on biomass production and plant phosphorus concentration equivalent to TSP in agricultural surface soil. In the second soil (with less active soil life and nutrient content), equivalence to TSP was achieved with combinations of two recycled fractions (P-Salt and dried solids). The enhancement of the phosphorus fertilizing effect by the solids was synergistic, indicating that the solids had a soil conditioning effect. The results show that biogas digestates are a valuable source for phosphorus recycling of fractions that have equivalent or even superior fertilizing properties compared to TSP.

Abstract Background Bioconversion of wood into bioproducts and biofuels is hindered by the recalcitrance of woody raw material to bioprocesses such as enzymatic saccharification. Targeted modification of the chemical composition of the feedstock can improve saccharification but this gain is often abrogated by concomitant reduction in tree growth. Results In this study, we report on transgenic hybrid aspen (Populus tremula × tremuloides) lines that showed potential to increase biomass production both in the greenhouse and after 5 years of growth in the field. The transgenic lines carried an overexpression construct for Populus tremula × tremuloides vesicle-associated membrane protein (VAMP)-associated protein PttVAP27-17 that was selected from a gene-mining program for novel regulators of wood formation. Analytical-scale enzymatic saccharification without any pretreatment revealed for all greenhouse-grown transgenic lines, compared to the wild type, a 20–44% increase in the glucose yield per dry weight after enzymatic saccharification, even though it was statistically significant only for one line. The glucose yield after enzymatic saccharification with a prior hydrothermal pretreatment step with sulfuric acid was not increased in the greenhouse-grown transgenic trees on a dry-weight basis, but increased by 26–50% when calculated on a whole biomass basis in comparison to the wild-type control. Tendencies to increased glucose yields by up to 24% were present on a whole tree biomass basis after acidic pretreatment and enzymatic saccharification also in the transgenic trees grown for 5 years on the field when compared to the wild-type control. Conclusions The results demonstrate the usefulness of gene-mining programs to identify novel genes with the potential to improve biofuel production in tree biotechnology programs. Furthermore, multi-omic analyses, including transcriptomic, proteomic and metabolomic analyses, performed here provide a toolbox for future studies on the function of VAP27 proteins in plants.
