Extrusion Blow Molding

The influence of six greenhouse cover types on the development of the vegetative phase of cultivated tomato plants (Lycopersicon esculentum Mill.) was analyzed. The cover films were manufactured by extrusion – blow molding. Special emphasis was put on measuring root, stem and leaf length and dry matter content of the plants, the results of which were compared to those obtained from plants sown outdoors. As expected, the cultivated plants exhibited more vigorous growth when compared to that of the plants grown under free exposure. Films additivated with polymers allowing higher percentages of light transmission and haze determined higher greenhouse inner temperatures, which, in turn, promoted biomass production in the plantation. The presence of an infrared blocker in the plastic film formulations prevented the temperature inside the greenhouses from decreasing drastically below the outer temperature overnight. Additives such as the UV absorber SMARTLIGHT RL1000™ and the red pigment IRGALITE BASF® 2BP™, which increase the amount of red light received by the plants, thus modifying the R:RF ratio, were found to affect the morphology of the studied plants. Although the effect of photomorphogenesis is weak, a slight decrease in the length and area of the tomato leaves could be observed when the R:RF ratio was high.

The root vegetables have a pivotal role in the vegetable consumption and to form a healthy diet. The consumption of natural juices, like apple-beetroot are becoming more popular and the drying-, the pharmaceutical- and canning industry require more beetroot to process. For the processing, the industry requires easily peeled and round shaped roots, therefore to use the proper variety is very important. The primary quality parameters are the inner color intensity, uniform color and water soluble dry matter content.4 beetroot varieties were evaluated (Libero, Rubin, Detroit 2 and Cylindra) in the 3 years experiment which was carried out at the University of Debrecen, Institutes for Agricultural Research and Educational Farm, Botanical and Exhibiton Garden. The soil type was calcareous chernozem. Leaf length, shape index and water soluble solid content were measured, and sensory evaluation was carried out on taste, inner color intensity and white ring.To summarize, we can state the exception of Rubin genotype all of the varieties are suitable for second cultivation and good for processing (canned, juice, powder).

This study assessed variability, heritability and correlations of agronomic traits in an onion (Allium cepa L.) landrace and derived S1lines after a single selfing generation. Bulbs used to develop S1lines were selected for shape, colour and high number of skins. Fifty-one S1lines and the original population were evaluated using an incomplete random block design. The original population and S1lines were highly diverse for quantitative and qualitative traits. S1lines were significantly different, with transgressive segregation for number and maximum leaf length, bulbing index, bulb weight, diameter, and dry matter content. Variances within S1lines were greater than among S1lines for all traits. Bulb colour and number of skins responded to selection. Heritabilities for dry matter and soluble solids were 52.6% and 36.1% respectively. Both traits were highly correlated. The development of S1lines allowed the expression of genetic variation and the identification of better genotypes for agronomic traits of interest.

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.

A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November 2012 to March 2013 to evaluate the response of three (3) wheat varieties viz., BARI Gom23, BARI Gom24 and BARI Gom25 under four levels of nitrogen fertilizer i.e, 75, 100, 125 and 150 kg N ha-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that plant height, number of leaves plant-1, leaf length and dry matter content were significantly affected due to varieties and/or nitrogen levels. Grains ear-1, number of fertile grains plant-1, 1000-grain weight, grain yield and harvest index were also significantly influenced by varieties and/or nitrogen levels. The value of all parameters studied in this experiment increased with increasing nitrogen levels up to 125 kg N ha-1 and thereafter decreased with fertilizer increasing level. Combination results showed that BARI Gom-24 with application of 125 kg N ha-1 gave the maximum grain yield (4.71 t ha-1), harvest index (49.37 %) and protein content (10.88%).Bangladesh Agron.

Abstract Salinity intrusion is a global concern in relation to sustainable agricultural practices. About three-fourths of the coastal area in Bangladesh is affected by different levels of salinity. This study was conducted to observe the effects of NaCl-salinity on tomato (Lycopersicon esculentum Mill.) plants in a pot experiment. Morphological properties and yield of five varieties of Bangladesh Agricultural Research Institute tomato (BARI-T 1, BARI-T 2, BARI-T 3, BARI-T 4, and BARI-T 5) plants were exposed to NaCl-salinity (2, 4, 6 and 8 dS/m) through irrigation. Morphological properties such as number of leaves, leaf length, leaf width, number of days of flowering, number of flowers and number of branches were observed. Results showed that morphological properties of all studied tomato plants were affected by increasing NaCl-salinity, except number of days of flowering, and yield was reduced compared to the control group (tap water; 0.043 dS/m). The post-harvest pot soil was also affected by NaCl-salinity irrigation. This study can be useful in selecting salt-tolerant varieties in saline-affected areas.

The experiment was conducted during March, 2016 to March, 2017 in a barojof experimental farm of Sher-e-Bangla Agricultural University, Dhaka. Thirteen betel vine cultivars designated as PB 001 through PB 013 were collected from different locations of Bangladesh and found remarkable variations in vegetative growth, morphological features, yield and yield attributes. The betel vine cultivars varied in vine elongation (37.46 – 50.34 cm per month), increase in internode length (6.75 – 10.08 cm per month) and vine girth (0.445 - 0.747 cm per year). The leaf length (17.13-27.35 cm), leaf breadth (8.33 - 16.20 cm), petiole length (4.83 -11.45 cm) and petiole breadth (0.47 - 0.28 cm) remarkably varied among the cultivars. Fresh weight of 100-petiole, 100-leaves, and dry matter content were 50.07 - 165.74 g, 289.38 - 565.25 g and 12.57 - 14.49%, respectively in different cultivars. Leaf number per meter vine (9.46 - 15.38) and leaf number per plant per year (50.16 - 78.44) were also varied among the cultivars. The highest annual per hectare yield was obtained from BARI Pan-1 (23.82 t) and PB 006 (23.46 t). Variations were also existed among the cultivars in vine colour, leaf colour, leaf shape, leaf tip, leaf softness and pungency of leaf of cultivars. No pungency of leaf was found in cultivars PB 006 (Misti pan). So, PB 006 (Misti pan) was seemed to be a better cultivar/ germplasm in respect of yield and quality of betel leaf.

AbstractLeafy vegetables are the source of many valuable components like vitamins, minerals and phenolic compounds as antioxidants. Chlorophyll derivatives have antioxidant and anticarcinogenic activity, or may even act as signalling molecules in organisms. However, during the storage of the leafy vegetables in the cold and darkness, numerous biochemical changes usually occurs, demonstrated as the breakdown of chlorophyll. Storage ability of plants depends to some extent on the conditions under which plants grew. Lamb’s lettuce plants were grown in the greenhouse in different light regimes - emitted with sodium (HPS-control) and LED lamps (100% red, 90% red + 10% blue, 70% red + 30% blue and 50% red + 50% blue light). The intensity of radiation at the height of the leaves of the plants was the same in every treatment. After harvesting, the plants were stored at the temperature of 5 °C and high humidity in plastic bags. The analyses of the material were done four times: after harvest and three times during storage at weekly intervals. Fresh weight lost, dry matter, phenolics and chlorophyll content were analysed. Additionally, the fluorescence of chlorophyll a was carried out. Changes in plant fresh weight and dry matter content during storage did not depend on the lighting used during cultivation. After 3 weeks of storage, higher value of indicator of the vitality of PSII (PIABS - Performance Index) was noticed in leaves treated with higher red light intensity during cultivation (100%, 90% and 70% red). LED lamps, which emitted 100% and 90% red light, enhanced concentration of total phenolics in lamb’s lettuce leaves. Light of HPS lamps decreased radical scavenging activity in leaves. Quality and usefulness of plants produced under LED lamps was just as good as those grown under HPS lamps.
