The nutritional quality of local food in the poor Kalimantan region will be lacking in minerals because the place for growing forage plants in a land with margins (acid) makes the quality of mineral poor food ingredients. The purpose of this study was to determine the nutritional quality of local feed supplemented with biocomplex ZN and Vitamin E. The treatment in this study used a complete design (CRD) with 4 processing repetitions made from 16 experimental units, consisting of (Tl) local forage-concentrates l2% PK without Zn and vitamin E supplementation, (T 2) Tl-supplementation + 60 mg Zn / kg as biocomplex Zn and vitamin E (T3) Tl + l20 mg Zn / kg such as Zn biocomplex + vitamin E and (T4) Tl + l80 mg Zn Biokomplek / kg + vitamin E. Parameters collected are the nutritional quality and digestibility of dry matter and feed organic matter. The results shown from studies using biocomplex ZN up to 180mg / kg of feed (PT3) can increase the protein content and dry matter content of local feed, and can increase the digestibility of local dry matter and organic feed ingredients. It was concluded that ZN Biokomplek and Vitamin E can improve the quality of local feed.

The effect of light intensity applied shortly before harvest on the nutritional quality, postharvest performance, and shelf life of loose-leaf lettuce (Lactuca sativa L. cv. Expertise RZ Salanova®) was investigated. Lettuce was grown either in a greenhouse with supplemental high-pressure sodium light (Experiment 1, EXP 1) or in a climate room under white LED light (Experiment 2, EXP 2). In both experiments full grown plants were transferred to a climate room for the End of Production (EoP) light treatments during the last week of cultivation. During EoP lighting plants were exposed to different intensities (0, 110, and 270 μmol m–2 s–1 in EXP 1; 50, 210, and 470 μmol m–2 s–1 in EXP 2) from white-red LEDs for 6 (EXP 2) or 7 days (EXP 1). Mature leaves were then harvested and stored in darkness at 10°C to study the postharvest performance. Changes in dry matter content, total ascorbic acid, and carbohydrates (including glucose, fructose sucrose, and starch) levels were determined during EoP lighting and during the subsequent shelf life as indicators of lettuce nutritional quality. Quality aspects (appearance, texture, and odor) were accessed during the shelf life as indicators of postharvest performance. In both experiments, high light intensities applied in EoP lighting increased dry matter percentage and contents of ascorbic acid (AsA) and carbohydrates at harvest and these increased levels were maintained during the shelf life. Increased light intensity in EoP treatment also extended the shelf life. The levels of AsA and carbohydrates at harvest correlated positively with the subsequent shelf life, indicating that the prolonged shelf life relies on the improved energy and antioxidant status of the crop at harvest.

SUMMARYThe effect of covers of controlled volunteer vegetation, Pueraria phaseoloides, and clean weeding on the soil moisture content and on the succulence of sisal leaves was studied. The surface soil tended to dry out further when exposed by clean weeding, but moisture in the profile as a whole was not much depleted. The plant covers dried soils to at least 300 cm. in dry periods. Although sisal leaves had a slightly higher dry matter content in dry weather there was no evidence of competition for water between the plant covers and the sisal.

Summary Modifications in growing techniques can affect the yield and nutritional quality of various cultivated plants. Among them, the use of biostimulants is environmental friendly method of stimulating crop productivity, stress resistance, and affecting yield or chemical composition of the plants. The aim of the investigation was determining of the effect of biostimulant treatment on yield and its quality of carrot grown for summer harvest. The experiment was carried out in 2009-2011 in the experimental station of the University of Agriculture in Krakow, south Poland. Two experimental factors were taken into consideration: (1) cultivar: Nandrin F1 and Napoli F1 (2) dose of Aminoplant (foliar application): 1.5 and 3.0 dm3∙ha-1 and control (without Aminoplant). Total and marketable yield, root length, its diameter, leaf mass and leaf : root mass ratio were assessed. The dry matter, soluble sugar, carotenoids and nitrate ions contents were analyzed as main determinants of carrot nutritional quality. Aminoplant influenced not only carrot productivity, but mainly chemical composition of the roots. The present results also suggest that carrot reaction to biostimulant treatment was depended on a cultivar more than on environmental conditions in particular growing seasons. The significant effect of Aminoplant in a dose of 1.5 dm3∙ha-1 on the yield of roots and leaf rosette mass of ‘Nandrin F1’ appeared only in the first year of the experiment. Spraying with Aminoplant in a dose of 3.0 dm3∙ha-1 significantly increased the soluble sugars content in carrot roots of both cultivars but only in 2011. Dry matter content was also affected by biostimulant treatment mainly for ‘Napoli F1’, which showed the lowest dry matter content when sprayed with Aminoplant in a dose of 1.5 dm3∙ha-1. In 2010 control plants contained the greater amount of carotenoids, while in next year roots of plants treated with Aminoplant in a dose of 3.0 dm3∙ha-1 had more these compounds. The significant effect of Aminoplant on nitrates content in carrot roots was observed but were not repeatable in the experimental years, so different climatic conditions modified carrot reaction on biostimulant spraying.

Eggplant is one of the most important vegetable crops known for its nutritive benefits due to the abundance of various bioactive compounds, which include proteins, vitamins, minerals, carbohydrates, phenolics, and dry matter content. In addition, eggplant has significant pharmaceutical properties that have been recently recognized. Eggplant produces secondary metabolites, including glycoalkaloids, antioxidant compounds, and vitamins, which appear to be the major source of its health benefits. It has been reported that there is a considerable correlation between the regular use of phytochemicals and the defense against diseases. Therefore, researchers must analyze the biochemical composition of eggplants to obtain more information about their nutritional quality and health benefits. In this review, an attempt is made to explain the qualitative and quantitative aspects of different biochemicals present in eggplant, in addition to their beneficial health effects.

The storage roots of arracacha have high nutritional value, being rich in carbohydrates, minerals, vitamins A and C, and starch of high digestibility. However, in this crop one of the decisive factors for the production of roots with higher nutritional value is the balanced fertilization. The aim of this study was to evaluate the yield and nutritional quality of storage roots of arracacha, grown at increasing levels of NPK fertilization. The experiment was conducted in the randomized blocks design, with eight replications. The treatments consisted of three NPK levels (AD0 = unfertilized cultivation, AD1 = cultivation with 50% of recommended fertilization, and AD2 = cultivation with 100% ofrecommended fertilization). It was observedthat higher levels of NPK fertilization increase the number, size and marketable yield of storage roots of arracachacrop. NPK fertilization also increases the size and contentsof K, Mg, and Mn of storage roots, without interfering with the pulp pH and contentsof protein, Ca, Cu, and Fe. However, when the increase in root size is not accompanied by an increase in dry matter content, the starch, P, and Zn contents of the roots reduce with increasing levels of NPK fertilization.

The objective of this study was to evaluate the nutritional quality of Tithonia diversifolia, a shrub species in the Asteraceae family and the diversity of uses in rural areas. A bibligraphic review was conducted in Mexico and other countries in Central America, South America, Africa and Asia. Bromatological analyses of edible material (leaves and petiole) were performed to determine dry matter (DM), fat, ash, crude fiber, crude protein (CP), and nitrogen-free-extract (NFE). Fiber fractions were determined: neutral deterget fiber (FDN), acid detergent fiber (ADF), hemicellulose, cellulose and lignin, from two locations in Jalisco state and one from Colima. Herbarium specimens were reviewed for knowing geographical distribution and rural uses. Results indicate that even without being legume, CP percentages are high with values of 18.42 to 31.54% with high dry matter content up to 98.92%, fiber values (30.81 to 34.08%) for NDF and (22.48 to 31.69%) for ADF. The bibliographic review highlights its forgae use, for ruminants and monogastrics, in beekeeping for its content of néctar and pollen, sucha as medicinal, ornamental and green manure for its contribution of nutritious, mainly phosphorus. T. diversifolia is a good option for its nutritional value and diversity of uses are demonstrated as an alternative in semi-intensive animal production systems in both tropical and temperate áreas.
