AbstractGiant leucaena (Leucaena leucocephala subsp. glabrata) can be managed as a profusely branched bushy plant by repeated harvest of its foliage for use as fodder. The objective of this research was to determine the effects of soil pH and salinity, age of the leaves, post-harvest storage duration, and psyllid infection on the nutritional qualities of leucaena fodder. To determine the effects of soil pH and salinity on fodder quality, giant leucaena K636 plants were grown in large pots containing soils adjusted to different pH and salinity levels. The effects of age of the leaves, post-harvest storage duration and psyllid infection on fodder quality were studied using leucaena samples collected from Waimanalo Research Station. Among five pH levels tested, pH 6.0 was found to produce the highest amounts of protein and structural fibers in the foliage. Mimosine contents were highest at pH 6 and 7 and lowest at pH 5.0. The growth of giant leucaena was retarded and the nutritional quality were adversely affected under salinity conditions. Compared to young leaves, old leaves contained 18.5% less protein, 95% less mimosine, 30% less tannin and 40% more structural fibers. Post-harvest storage duration up to 72 h, at room temperature did not seem to affect protein, tannin and structural fiber contents of the foliage; however, mimosine content was reduced by 25%. These results will help to identify ideal soil pH, age of foliage, and post-harvest storage duration for obtaining high forage yield and nutritional quality for giant leucaena.

More food with high nutritional content will be needed to feed the growing global human population, which is expected to reach 10 billion by 2050. Fruits and vegetables contain most of the minerals, micronutrients, and phytonutrients essential for human nutrition and health. The quantity of these phytochemicals depends on crop genetics, weather and environmental factors, growth conditions, and pre-harvest and post-harvest treatments. These phytochemicals are known to have anti-cancer properties and to regulate immunity, in addition to hypolipidemic, antioxidant, anti-aging, hypotensive, hypoglycemic, and other pharmacological properties. Physical treatments have been reported to be effective for managing several post-harvest diseases and physiological disorders. These treatments may affect the external, internal, and nutritional qualities of fruits and vegetables. Therefore, the aim of this review is to summarize the information recently reported regarding the use of physical treatments applied either directly or in combination with other means to maximize and maintain the phytochemical content of fresh and fresh-cut or processed fruits and vegetables.

Coffee growing areas in Andhra Pradesh and Orissa (non-traditional area - NTA) are characterized by undulating topography with terraced slopes having narrow valleys with scattered coffee farms across the elevation of the Eastern Ghats of Vishakhapatnam (Andhra Pradesh) and Koraput (Orissa) districts. Under this situation plant available nutrients will become non-available and the nutrients are stored in several pools as inorganic and organic forms in soil exchange complex are very much essential for coffee plants for its growth and development. Hence, a study was conducted to know the soil nutrient status of coffee growing region of NTA. A total of 693 surface soil samples were collected at depth of 22cm randomly from each coffee growing mandals of NTA and assessed the nutrient status (soil pH, OC, available P and K) at Regional Coffee Research Station, Narsipatnam. Results of the soil test results indicated that most of the Arabica coffee soils of NTA are acidic in reaction (72 %) and soil pH > 6.0 in these soils was 28 % in the tested soils. Plant available phosphorous (P) in the soil is low with 33 % soils and 46 % of the soils are medium in range. However, only 21 % of the soils tested are high in available phosphorous content in these soils. The majority of the soils of this region are high in available potassium about 54 % and 31 % of the soils are medium in range but only 15 % of the soils are low in available K status. Coffee soils of NTA are rich in organic carbon status and almost 47 %. 33 % of the tested soils are medium in range but 19 % of soils were low in organic carbon status. Soils are slightly acidic in reaction and were rich in organic carbon and available potassium status.

Yellow sweet peppers (Capsicum annuum L. cv. Dinamo) are generally more susceptible than red sweet peppers to physiological and pathological deterioration after harvest. Yellow peppers also fetch higher prices at market. In this study, we examined the external and nutritional quality attributes of yellow pepper fruits stored at suboptimal temperatures of 1.5 and 4 °C for 3 weeks, followed by a 3-day shelf-life simulation. Notably, yellow peppers kept in plastic (Xtend®, Stepac, Tefen, Israel) bags at 4 °C maintained their external quality just as well as peppers stored at the optimum temperature of 7 °C. In addition, nutrient content (namely ascorbic acid) and total phenolic and hydrophilic antioxidant contents were not reduced when the peppers were kept at suboptimal storage temperatures of 4 or 1.5 °C in Xtend® plastic packaging. Thus, the external and nutritional qualities of yellow pepper fruits can be preserved at suboptimal temperatures of 4 °C with Xtend® plastic packaging. This is particularly significant in light of the fact that storage at such temperatures is sometimes used as a quarantine method to eliminate pests on produce imported into Israel.

Earthworm species composition, the density of individuals, and their biomass were investigated in spring barley and faba bean fields in a long-term (52-year) experiment conducted at the Production and Experimental Station in Bałcyny, in north-eastern Poland (53°40′ N; 19°50′ E). Additionally, post-harvest residues biomass, soil organic matter (SOM), and soil pH were recorded. The above traits were investigated using two experimental factors: I. cropping system—continuous cropping (CC) vs. crop rotation (CR) and II. pesticide plant protection: herbicide + fungicide (HF+) vs. no plant protection (HF−). A total of three species of Lumbricidae were found: Aporrectodea caliginosa (Sav.) in both crops, Aporrectodea rosea (Sav.) in spring barley, and Lumbricus terrestris (L.) in faba bean. The density and biomass of earthworms were unaffected by experimental treatments in spring barley fields, whereas in faba bean CC increased and HF+ decreased earthworm density and biomass in comparison with CR and HF− respectively. Total post-harvest residues in faba bean fields were higher under CC in relation to CR and under HF+ compared with HF− treatment in both crops. Compared to CR, CC increased soil pH in spring barley fields and decreased in faba bean fields. Experimental factors did not affect SOM. Earthworm density and biomass were positively correlated with SOM content.

Processed food is associated with unhealthy qualities such as higher content of harmful fats, sugars and salt. The aim of our study was to compare the nutritional qualities of supermarket’s own brands and regular brands of bread sold in Sweden. Additionally, we compared the nutritional qualities of gluten-free and gluten-containing bread. We collected information from the labels of 332 bread products available in the largest grocery store chains. The Australian Health Star Rating (HSR) system was used to quantify the nutritional quality of each bread product. We compared all supermarket’s own brand products to regular brand products, and gluten-free to gluten-containing bread. The mean HSR for the supermarket’s own brands was lower than the regular brands (3.6 vs. 3.7; p = 0.046). For the regular brand products, the fibre, sugar and total fat content were greater (p < 0.001, p = 0.002 and p = 0.021, respectively), while less protein (p = 0.009) compared to regular bread products. Gluten-free bread had a lower HSR than gluten-containing bread (mean 3.5 vs. 3.8, respectively; p < 0.001). The regular brand products were slightly healthier than the supermarket’s own brands, primarily as a result of a higher fibre content. Gluten-free bread products were slightly unhealthier due to a lower protein content.

Three autotetraploid maize synthetics were compared with four diploid synthetics of similar adaptation in yield trials and growth analysis experiments at several southern Ontario locations, in order to assess the potential of tetraploid maize as a source of forage. No differences were observed among ploidy levels in productivity of whole-plant dry matter, or in nutritional quality of forage. Tetraploids appeared to be lower in dry matter content at harvest and through much of their period of growth.Key words: Silage corn, forage corn, autotetraploid, (Zea mays L.)

Staple Crop

Cassava (Manihot esculenta Crantz) is the staple food source for over 850 million people worldwide. Cassava contains cyanogenic glucosides and can be toxic to humans, causing paralysing diseases such as konzo, and even death if not properly processed. Konzo epidemics are often associated with times of drought. This may be due to a greater reliance on cassava as it is drought tolerant, but it may also be due to an increase in cyanogenic glucosides. Episodic droughts are forecast to become more common in many cassava-growing regions. We therefore sought to quantify the effect of water-stress on both yield and cyanogenic glucoside concentration (CNc) in the developing tubers of cassava. Five-month-old plants were grown in a glasshouse and either well watered or droughted for 28 days. A subset of droughted plants was re-watered half way through the experiment. Droughted plants had 45% fewer leaves and lower tuber yield, by 83%, compared with well-watered plants. CNc was 2.9-fold higher in the young leaves of droughted plants, whereas CNc in tubers from droughted plants was 4-fold greater than in tubers from well-watered plants. Re-watered plants had a similar biomass to control plants, and lower CNc than droughted plants. These findings highlight the important link between food quality and episodic drought.

The condition of seagrass beds in Amahai Bay is relatively fertile, with a fairly high and wide density. Enhalus acoroides was chosen as a type of seagrass used for transplants in this study because Enhalus acoroides was quite abundant in the waters of Amahai Bay. Seed availability is one of the factors that need to be considered in the transplant business. There are several points in the waters of Amahai Bay where seagrass conditions do not grow evenly. Many fishermen who do fishing activities in the seagrass area inadvertently damage the ecosystem in the seagrass beds in that location. Under these conditions, it is important to do seagrass transplants so that the seagrass ecosystem is not increasingly damaged due to many human activities or natural factors. This experimental field research was carried out comparing the growth of transplanted seagrass Enhalus acoroides using the anchored sprig method. Determination of the location of the study carried out by the method of purposive random sampling. The research station in the waters of the village of Amahai at the substrate location of the muddy sand bottom with a depth of 0.85-1.5m. The station is divided into 3 observation points, with each location given 3 plots of 1x1m size with a transplant of 16 stands in each plot. The highest leaf growth rate for transplanted seagrass is at station 2, which is 3.76 mm.hr-1 on young leaves and 1.86 mm.day-1 for old leaves. And there is a difference in the speed of growth between the growth of natural seagrass and transplanted seagrass. The difference in transplantation stations has a very significant effect on the growth of seagrass leaves.

The Impact

The changes of soil pH and dry forage yield of permanent grassland after application of dolomitic limestone and stabilized nitrogen fertilizers are described in this paper. The small‑plot experiment was located on semi‑natural grassland at Bohemian‑Moravian Highlands, near village Kameničky (Czech Republic), with poor and acidic soil. The experiment was divided into two blocks, within one of whose dolomitic limestone was applied in autumn 2013. In each block, 4 experimental treatments were applied: 1. control (untreated), 2. Urea, 3. Urea with inhibitor of urease, 4. Urea with inhibitor of nitrification. After liming, the pH/CaCl2 soil values increased in both the first as well as the second year after application. Fertilizing by urea, namely urea with inhibitors, did not significantly influence the pH/CaCl2 values. Dry forage productions in both years were comparable. In comparison to the untreated variants, significant increase in dry forage yield was achieved after application of urea and urea with urease inhibitors. The impact of stabilized fertilizers on the yield was not proven. In case of the limed variants, yield drop by 1.12 t/ha (average of both years) was observed; the yield decrease may be connected with disturbance of production potential of the stable community of plant species that had been adapted to acidic locations.
