Abstract Temulawak produces bioactive compounds that have antioxidant activity and changes in its chemical composition are caused by environmental pH. Sulphur is an essential nutrient for plants and a constituent of several coenzymes and vitamins that play a role in plant metabolism. Marginal calcareous land in Tuban is generally used as teak production forest, because food crops cannot grow optimally in this land. Temulawak is a shade-tolerant plant that can grow well in conditions of low light intensity. The objective of this research is to obtain the appropriate goat manure and sulphur fertilizer dosages for temulawak planted beneath teak stands on calcareous marginal soil in order to maximize its yield and quality. The field experiment was RCBD with three replications and two factors: manure level (10, 15 and 20 t ha-1) and ZA level (0, 40, 80 and 120 kg ha-1). The results showed that a higher fresh weight of rhizomes per clump was obtained in combination of 10 and 15 ha-1 manures and 40 kg ha-1 sulphur fertilizer. Similar high yield is obtained when 20 t ha-1 of manure is applied in combination with 80 kg ha-1 of sulphur. In addition, a higher curcumin content and antioxidant activity were obtained in plant treated with 10 t ha-1 manure without S fertilizer. Similar high curcumin content and antioxidant activity of the rhizome were also obtained from rhizome treated with 15 t ha-1 of manure in combination with 40 kg ha-1 sulphur fertilizer and 20 t ha-1 manure without sulphur fertilizer.

Lentil is a versatile and profitable pulse crop with high nutritional food and feed values. The objectives of the study were to determine suitable locations for high yield and quality in terms of production and/or breeding, and to identify promising genotypes. For this reason, five lentil genotypes were evaluated in a multi-location network consisting of ten diverse sites for two consecutive growing seasons, for seed yield (SY), other agronomic traits, crude protein (CP), cooking time (CT) and crude protein yield (CPY). A significant diversification and specialization of the locations was identified with regards to SY, CP, CT and CPY. Different locations showed optimal values for each trait. Locations E4 and E3, followed by E10, were “ideal” for SY; locations E1, E3 and E7 were ideal for high CP; and the “ideal” locations for CT were E3 and E5, followed by E2. Therefore, the scope of the cultivation determined the optimum locations for lentil cultivation. The GGE-biplot analysis revealed different discriminating abilities and representativeness among the locations for the identification of the most productive and stable genotypes. Location E3 (Orestiada, Region of Thrace) was recognized as being optimal for lentil breeding, as it was the “ideal” or close to “ideal” for the selection of superior genotypes for SY, CP, CT and CPY. Adaptable genotypes (cv. Dimitra, Samos) showed a high SY along with excellent values for CP, CT and CPY, and are suggested either for cultivation in many regions or to be exploited in breeding programs.

AbstractIn this article, we present the genomic DNA yield and the microsatellite and single nucleotide polymorphism (SNP) genotyping success rates of genomic DNA extracted from a large number of mouth swab samples. In total, the median yield and quality was determined in 714 individuals and the success rates in 378,480 genotypings of 915 individuals. The median yield of genomic DNA per mouth swab was 4.1 μg (range 0.1–42.2 μg) and was not reduced when mouth swabs were stored for at least 21 months prior to extraction. A maximum of 20 mouth swabs is collected per participant. Mouth swab samples showed in, respectively, 89% for 390 microsatellites and 99% for 24 SNPs a genotyping success rate higher than 75%. A very low success rate of genotyping (0%–10%) was obtained for 3.2% of the 915 mouth swab samples using microsatellite markers. Only 0.005% of the mouth swab samples showed a geno-typing success rate lower than 75% (range 58%–71%) using SNPs. Our results show that mouth swabs can be easily collected, stored by our conditions for months prior to DNA extraction and result in high yield and high-quality DNA appropriate for genotyping with high success rate including whole genome searches using microsatellites or SNPs.

Early blight is one of the most common and destructive tomato disease and it is caused by the fungus Alternaria solani. The aim of this paper was to screen the reaction of ten tomato genotypes (collection of the Institute of Field and Vegetable Crops) against natural infection of early blight. Tested genotypes showed significant differences in the disease occurrence on leaves but not on fruits. However, at the biochemical level, total phenolics (TP), tannins (TT), flavonoids (TF) and antioxidant activity in tomato fruits was significantly affected by genotype, disease occurrence and interaction of these two factors. According to obtained results, content of these secondary metabolites could be used as a one of the parameters in the evaluation of tomato resistance to EB.

Aquilaria is one of the plant genus-producing agarwood. Aquilaria leaves have pharmacological effects which the potential to be processed into black tea. The aim of this study is to determine the effect of fermentation duration on physicochemical and organoleptic characteristics of Aquilaria leaves tea. This study employed a Completely Randomized Design with two factors; the plant species (A. crassna, A. malaccensis, and A. subintegra) and fermentation duration (0 minutes, 70 minutes, and 90 minutes). Parameters analyzed including water content, total phenol, and antioxidant activity. Organoleptic tests were performed on the color, taste, and aroma of the brewed tea. The results summarized that A. subintegra had the highest total phenol and antioxidant activity, but the taste of the tea was not favored. A. crassna fermented 70 minutes and A. malaccensis fermented 0 minutes were the most preferred, but both have lower total phenol and antioxidant activity than A. subintegra.

Food Security And Nutrition

Rice is the world’s largest food crop, and its production needs to be doubled by 2050 to cope with population growth and associated demand. In addition to the value of improving yields, quality is also important for breeders and consumers, but it pays less attention in arid regions. During two successive summer growing seasons, the experimental material focused on 34 genotypes developed from different crosses on Fn generation after fixation as well as six of the most recent commercial cultivars used for comparisons. The results showed that a high yield of grain followed by high milling and grain quality characteristics were observed among the 34 genotypes used in this analysis. Highly important and positive correlations between the percentage of hulling and the percentage of milling (0.424) and the yield ability could be accomplished by choosing the number of panicles per plant and the weight of the panicles. Selection criteria for good quality should be met by the percentage of head rice and many mineral elements, particularly zinc and iron. As a consequence, the genotypes M.J 5460S/SK105-1, M.J 5460S/GZ7768-1, M.J 5460S/G177-1, M.J 5460S/SK105-3 and M.J 5460S/SK106-4 had desirable high yield and quality characteristics and could be used as promising accessions to the rice breeding program in arid regions. In addition to commercial genotypes, improved Japonica rice genotypes could be produced in arid conditions for higher yield and quality, leading to an increase in total production, supporting food security and nutrition.

Abstract Fertilizers are materials that provide the essential nutrient elements required for crop growth. The primary objective of applying fertilizers is to achieve an optimum plant response in terms of crop yield and quality, while at the same time minimising nutrient losses due to leaching and volatilisation. Fertilizers have become so important to plant growth that they are now responsible for approximately half of the world's crop production, supplying food, feed, fibre and fuel for a global population that is expected to reach 9 billion before the middle of the 21st century (Reetz, 2016).
