An experimental investigation of performance levels in a new root crown cleaner
(2019)For the purposes of carrying out field experiments using the vertical-type cleaner with its elastic cleaning blades to remove haulm residues from the crowns of standing roots, the programme for this process and the ... -
RGB vegetation indices applied to grass monitoring: a qualitative analysis
(2019)In developing countries such as Brazil, research on low-cost remote sensing and computational techniques become essential for the development of precision agriculture (PA), and improving the quality of the agricultural ... -
Spatial variability of litter temperature, relative air humidity and skin temperature of chicks in a commercial broiler house
(2019)The thermal environment inside a broiler house has a great influence on animal welfare and productivity during the production phase. Among the importance of the chicken litter is the function of absorbing moisture, provide ... -
Formation of photosynthetic and grain yield of spring barley (Hordeum vulgare L.) depend on varietal characteristics and plant growth regulators
(2019)The aim of the study was to determine the efficiency of the barley treatment crops with modern retrograde preparations on the background of the mineral fertilizers introduction into the photosynthetic activity of crops ... -
Variety, seeding rate and disease control affect faba bean yield components
(2019)Faba beans (Vicia faba L.) have been grown since 8000 years B.C. in the Middle East. Despite their long growing history in the world, there are only few researches carried out in Baltic region in last decades about ... -
Effect of two housing systems on performance and longevity of dairy cows in Northern Italy
(2019)The objective of the current study was to evaluate and compare performance of dairy cows housed in compost-bedded pack barns (CBP) and free stall barns, with a focus on longevityrelated parameters. Study included 30 ... -
Comparison of lycopene and β-carotene content in tomatoes determined with chemical and non-destructive methods
(2019)Tomatoes are one of the most popular vegetables due of their wide use as food. Tomatoes are not only tasty fruit, but one of its benefits - high carotenoids content is well-known. Non-destructive analyses methods are ... -
Principal components in the study of soil and plant properties in precision coffee farming
(2019)In this work, a principal component analysis was performed to evaluate the possibility of discarding obsolete soil and plant variables in a coffee field to eliminate redundant and difficult-to-measure information in ... -
Assessment of applied microwave power of intermittent microwave-dried carrot powders from Colour and NIRS
(2019)Applied microwave (MW) power level is an essential factor on the quality of the dried agricultural products. Even if higher MW powers result in shorter drying times, they lead to quality degradations. It is almost ... -
Model for ammonia emissions’ assessment and comparison of various dairy cattle farming systems and technologies
(2019)A dairy cattle farming is an important source of ammonia emissions, particularly in Latvia. Models using a wide range in level of detail have been developed to represent or predict these emissions. Besides, models are ... -
Spatial distribution of thermal variables, acoustics and lighting in compost dairy barn with climate control system
(2019)The main objective of this research was to evaluate the spatial distribution of the thermal variables, acoustics and lighting in climate controlled compost dairy barn. The experiment was conducted in October 2017, in a ... -
Effect of environmental temperature during the of brooding period on growing period of pullets viscera and tibia
(2019)Poultry production in subtropical and tropical regions faces many problems, one of which is the high air temperature causing thermal stress, particularly dangerous in high-producing birds. Thus, the negative effects ... -
Estonian dairy farms’ technical efficiency and factors predicting it
(2019)Milk production is a complex process whose efficiency depends directly on the inputoutput ratio and indirectly on the decisions made at farm and animal level. Decisions made about farm hygiene, dairy cows’ milk yield, ... -
Modeling the functional role of the microorganisms in the daily exchanges of carbon and nitrogen in intercropping system under Mediterranean conditions
(2019)Carbon (C) and nitrogen (N) sequestration in plants and soil micro-organisms is considered as a major phenomenon against global warming. The modeling of this phenomenon aims at highlighting the role that the legumes-cereals ... -
Evaluating the effects of application modes and soil types on the herbicide efficacy and crop yield of pendimethalin and clomazone on transplanted pepper (Capsicum annuum L.)
(2019)Field experiment was carried out in 2014 and 2015 in two locations Kochani and Drachevo in Republic of Macedonia to evaluate the efficacy and crop safety of pendimethalin and clomazone on transplanted pepper according ... -
The effect of Minituber Weight on their Field Performance under a Northern European environment
(2019)Weight of potato minitubers as well cultivar affects field performance of minitubers. The aim of this study was to compare minitubers of four weight classes (MtC) (3 to 4.99 g, 5 to 9.99 g, 10 to 19.99 g, and > 20 g) ... -
Ranking irrigation schemes based on principle component analysis in the arid regions of Turkey
(2019)Water is a scarce resource and thus irrigation schemes in arid regions have become more important. The irrigation sector which uses most of the water resources has to cope with global warming, disasters and water scarcity ... -
Effect of nitrogen rate and forecrop on nitrogen use efficiency in winter wheat (Triticum aestivum)
(2019)Application of plant nutrient is one of the most important measures increasing grain yield and yield quality. Excessive application of nitrogen fertilizers leads to nitrogen leaching and it affects the quality of groundwater ... -
