The concept of photo-selective netting was studied in a sweet pepper (Capsicum annuum L.) cultivar 'Cameleon' from summer cultivation south Serbia (under high solar radiation 910 W m -2 , with photosynthetic photon flux density 1661 µmol s -1 ), under four different coloured shade-nets (pearl, red, blue and black) 40% relative shading.The aim the study to determine how environmental control technologies, as net house or plastic-house integrated shade-nets, could influence plant parameters,...

Tillage systems can affect soil compaction, water content, temperature, and yields of cultivated plants. This work examined a Vertisol the influence tillage system on compaction yield winter wheat (Triticum aestivum L.) grains. The trial was conducted in vicinity Požega, Western Serbia, from 2014 to 2017. Four (conventional tillage, reduced disc harrowing, no-tillage) were applied experiment. have significantly influenced measurement time, depth. Mean 2016- 2017 1.96 MPa, which 0.17 MPa...

The purpose of this study was to examine differences between postharvest treatments, either washed (hot water, H2O2 and Na2OCl) or non-washed (control) carrot roots the effect different storage conditions, S1 (0°C > 95% RH) S2 (0-2°C < 90% on compositional changes. Losses mass, Beta-carotene vitamin C in taproot (Daucus carota L. cv.’Maestro F1’) were monitored during 160 days cold (in both room) plus 20 at 20°C (market simulation). At end 180 percentage mass loss ranged from 3.1 33.2%...

The objectives of this study were to investigate the effects coloured shade-nets (pearl, blue, or red all with a 50% shade index) compared non-shaded plants on quality traits Discoa and ICE 40102 (green-leaf) Eglantine (red-leaf) lettuce cultivars. Total chlorophyll content depended shading genotype. b contents higher in shaded than unshaded plants. cv. had highest total chlorophylls (637.03 μg∙g-1 F.M.) content. carotenoid was leaves under pearl nets (208.89 F.M). phenols (76.70±1.9 mg∙g-1...

In agricultural production, pests and diseases of crops, as well weed plants, cause significant losses in the yield quality products. One most effective ways fighting is use a wide range chemicals called pesticides. accordance with EU Directives 2009/128/EC 2006/42/EC underlying standard EN 13790, Plant Protection Administration Ministry Agriculture Environment Republic Serbia has established framework for control sprayers mist blowers. Maintaining pesticide application good state repair...

The results of the examination sowing density and meteorological conditions on productive traits several genotypes winter triticale are presented in this paper.The was conducted vicinity Bijelo Polje, northern part Montenegro period 2009-2012.The experiment, set randomized block system with three replications included five varieties (Odysseus, Kg-20, Triumph, Rtanj Tango) two rates (density) -600 800 germinated seeds per m -2 .Common agronomical practices were used application NPK fertilizer...

At present, spreading of mineral fertilizers in Europe is most commonly performed using centrifugal disk spreaders with attached vanes. The motion an ideal spherical homogeneous fertilizer particle along the straight vane to a flat rotating disc was analyzed this paper. analysis non-inertial reference coordinate system. From assumptions introduced enable analytical describing real as well general tools solid mechanics, ordinary in-homogenous second-order differential equation having constant...

The paper presents the three years efficiency results (2011-2013) of work and ways harvesting (three types mowers, with or without spreading forage) influencing quality forage (the content crude protein fiber) during days drying process. These indicate that method can strongly affect efficiency, energy consumption, intensity used for hay haylage preparation. best was achieved when a drum rotating mower PÖTTINGER CAT 185 used. Negative correlation found between fibre content, depending on...

Triticale production on acid soils requires signifcant investments in repairing bad qualities of those and it raises the question about proftability triticale growing. The aim our study was to determine yield soil depending dose type applied fertilizer, as well economic feasibility application fertilizers soils. experiment performed at Centre for Agricultural Technological Research Zajecar, during 2009-10 years. It a set-by-bloc system with three repetition included control variants...

The dry down rate of corn grain during maturation is influenced by a large number environmental factors and properties hybrids, has major effect on corn, reaching its full maturity. This especially important for the timely soil tillage planting next culture. aim this research was to determine yield from grains depending hybrid sowing term, in agro ecological conditions South Serbia (Leskovac). For purpose, an experiment made 2016 2017 territory municipality Leskovac. Soil type alluvium....
