Effect of Container Volume and Planting Density on Ginger and Turmeric Growth and Yield

Domestic production of ginger (Zingiber officinale) and turmeric (Curcuma longa) rhizomes is increasing. The objective of this study was to compare growth and rhizome yield of these crops using different container volumes and planting densities. Two greenhouse experiments that lasted 28 weeks each were conducted. In Expt. I, one sprouted rhizome of a single ginger variety (Bubba Blue) and four turmeric varieties (Hawaiian Red, BKK, White Mango, and Black) were transplanted into either small (1.5 gal) or large (13.3 gal) round containers. In Expt. II, either one or three sprouted rhizomes of two ginger varieties (Bubba Blue and Madonna) and two turmeric varieties (Indira Yellow and Hawaiian Red) were transplanted into either large (13.3 gal) or medium (3.9 gal) round containers. In Expt. I, there were an increase in plant growth and yield with increasing container volume, as both crops produced more than double the shoot, root, and rhizome fresh weight (FW) when grown in large compared with small containers. In Expt. II, rhizome yield of ginger was 44% higher in medium than large containers, and container volume did not affect yield in turmeric. Total dry weight (DW) was higher in plants grown in the larger container volume in both species in Expt. I, and turmeric only in Expt. II. However, ginger in Expt. II had an 18% higher plant DW in the medium compared with the large container. The higher density in Expt. II increased yield and biomass production per container compared with the lower density, regardless of variety and container volume. Overall, net revenue per container was higher in Expt. II than Expt. I because of the higher rhizome yield. In Expt. I, the higher yield of ginger compared with turmeric increased sales revenue of this species, despite a lower sales price per kilogram. In contrast, the higher yield of turmeric in Expt. II resulted in higher sales revenue and net revenue per container compared with ginger. Based on our results, medium containers could be used to minimize material and space costs for ginger and turmeric production under the conditions evaluated in our study.

Exploring the Potential of Jackfruit (Artocarpus heterophyllus Lam)

Background: Jackfruit (Artocarpus heterophyllus Lam) is widely cultivated in tropical and sub-tropical areas worldwide. The tree is highly productive, resilient, and requires minimal care. Jackfruit has a characteristic flavour and is highly versatile. Several studies report the importance of the tree and fruits, ranging from food and medicine to the provision of several value-added products. In spite of the many benefits the plant offers, it has not been sufficiently incorporated in the general food system, partly because of gaps in processing, distribution and knowledge about utilization methods and nutritional and nutraceutical value.
 Objective: A comprehensive literature search was done to highlight jackfruit's nutritional, health, and commercial benefits to promote its utilization.
 Methodology: The literature search was conducted using three electronic databases with no constraints on publication year. Over 200 studies on the nutritional properties of jackfruit and at least 105 articles on the use of the various parts of the jack tree for their anticarcinogenic, antimicrobial, antifungal, anti-inflammatory, and hypoglycemic effects were found.
 Findings: Jackfruit has vital nutrients, including phytochemicals, minerals, vitamins, carbohydrates, and proteins. The literature on utilization shows that the fruit can be processed into commercial products using minimal processing technologies, dried to extend product shelf-life, or processed into various value-added products.
 Conclusions: Jackfruit production and value addition are relatively under-developed despite the fruit tree’s high yield potential, high nutritional value, nutraceutical and techno-functional properties. For improved benefits from jackfruit, actors need to adopt the available technologies at different value chain nodes.

NMR-based metabolomics for elucidating the bioactive compounds from Mangifera caesia Jack and Ficus auriculata lour.

Mangifera caesia and Ficus auriculata are neglected fruits found in Malaysia and are locally known as "buah binjai" and "buah ara", respectively. To profile the metabolites for both fruits, we conducted a robust 1 H-nuclear magnetic resonance (NMR)-based metabolomics approach. Principal component analysis (PCA) and partial least square (PLS) analyses were applied to distinguish the metabolites variations of M. caesia and F. auriculata fruits extracted with different ethanol ratios (0, 70, and 100%). In total, 34 metabolites were identified in M. caesia and F. auriculata fruits. The 70% ethanol extracts of both fruits displayed the highest antioxidant and α-glucosidase inhibitory activities, as well as notable with the highest phenolic content, compared with the other samples. The present metabolomics study shows that the polarities of solvent extractions play a crucial role in the assessment and recovery of the metabolites for the high value of natural antioxidants and α-glucosidase inhibitors in M. caesia and F. auriculata fruits. PRACTICAL APPLICATIONS: Antioxidant and antidiabetic agents from fruit sources are increasingly becoming popular due to its potential contributions to human health, by protecting against infections and degenerative diseases. However, some of these fruits were neglected where the scientific data on their potential benefits and biochemical contents are lacking. The information gained from this study provides valuable knowledge on M. caesia and F. auriculata fruits as natural antioxidant and α-glucosidase inhibitors agents that might be beneficial to consumers, further promote the usage of neglected fruits as functional food and natural supplements.

Antioxidant and α-glucosidase inhibitory activities of eight neglected fruit extracts and UHPLC-MS/MS profile of the active extracts.

The 70% ethanolic extracts from eight neglected fruits; Muntingia calabura, Leucaena leucocephala, Spondias dulcis, Syzygium jambos, Mangifera caesia, Ardisia elliptica, Cynometra cauliflora and Ficus auriculata were evaluated for their 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, α-glucosidase inhibitory activities as well as total phenolic content. The results of this study revealed that M. caesia fruit extract demonstrated the most potent radical scavenging activity. Among the fruits examined for α-glucosidase inhibitory activity, M. calabura and F. auriculata exhibited strong activity with no significant difference. The Pearson correlation indicated that the activities of M. caesia and F. auriculata contributed by phenolic compounds. A total of 65 metabolites were tentatively identified by using ultra-high-performance liquid chromatography tandem mass spectrometry (UHLPC-MS/MS). These findings suggested that the possible application of M. caesia and F. auriculata as a functional food with antioxidant and α-glucosidase inhibitory properties.

Effect of rice husk biochar application on rice yield, methane emission and soil carbon sequestration in paddy growing Ultisol

Soil health emphasizes the integration of physical, chemical and biological measures of soil quality that affect farmers profit and the environment. Recently, biochar is recognized as soil amendment in agriculture though the technology still remains underutilized. Biochar application is an effective option for promoting soil carbon sequestration, a component in soil quality. Rice husk biochar (RHB) produced from pyrolysis of rice husk (RH) is characterized by a higher nutrient content as compared to wood-derived biochar. A field study was conducted to evaluate the short-term effects of translocation and distribution of RHB derived nutrients in rice crop and their effects on soil nutrients, rice productivity and methane (CH4) emission in paddy growing Ultisol. The treatments included fertilization with four organic sources [farm yard manure (FYM), jack tree (Artocarpus heterophyllus) leaves, daincha (Sesbania aculeata) and rice husk biochar along with a control (no organic manure)] in combination with inorganic nitrogen applied @ 35 (N1), 70 (N2) and 105 (N3) kg N ha-1 through urea. The results showed that the RHB application improved the short-term soil organic carbon (SOC) gain and rice grain and straw yield. The brown rice yield increased with higher N application rates. RHB supplied significant amounts of C to the paddy soil which was recalcitrant and this increased the soil carbon content after rice cultivation. This in turn had significant effect in reducing 50- 60% CH4 emission from soil compared to FYM.
