Productivity of crops of field rotation in contrasting growing seasons

Lazauskas, S., Lithuanian Research Centre for Agriculture and Forestry, Akademija et al. [2015]

Given the need for sustainable intensification of crop production, experimental assessment of factors contributing to yield variability and uncertainties in nutrient balances in a field crop rotation is essential. The study, aimed at performance of crops under different management in relation to weather conditions, was conducted during 2008-2011 at the Institute of Agriculture, Lithuanian Rese ...

The effect of catch crop nitrogen on soil properties and spring barley yield

Arlauskiene, A., Lithuanian Inst. of Agriculture, Joniskelis et al. [2008]

During the period 2001-2004 field experiments were carried out at the Lithuanian Institute of Agriculture's Joniskelis Experimental Station on clay loam soil. The experiments were designed to elucidate the mobilization of soil nitrogen by the catch crops oil radish (Raphanus sativus L.), white mustard (Sinapis alba L.), red clover (Trifolium pratense L.), cocksfoot (Dactylis glomerata L.), Ita ...

Soil nitrogen availability for crops

Karklins, A., Latvia Univ. of Agriculture et al. [2014]

All possible sources of nitrogen available for crops before decision is made for the use of commercial fertilisers is necessary according to the requirements of Nitrate directive and adjustment documents regulating fertiliser use planning. Soil together with crop residues is one of nitrogen supplying sources, but quantifying amounts which could be released in plant available form and take part ...

The main task of bees is pollination. The results achieved with pollination are many times higher than the value of the products of these insects. Due to changes in production technologies, reduction of the surface of nonproductive areas, environmental pollution and improper use of pesticides, the importance of bees in pollination is constantly growing. This applies especially to countries wit ...

Crop diversity and productivity under organic farming in Lithuania

Arlauskiene, A., Lithuanian Research Centre for Agriculture and Forestry et al. [2015]

In Lithuania, the land area under organic management has been steadily increasing over the recent years. A research and development project was implemented in Lithuania with the aim of ascertaining crop structure, plant diversity and crops productivity in organically-managed farms under different soil conditions. In mixed farms, involved both in crop and animal production, perennial forage gra ...

Green manure and catch crops are main tools in the maintenance and improvement of soil fertility in organic farming. What are the above-ground dry matter yields and nitrogen uptake efficiencies of different green manure and catch crops? These issues were investigated in 2013-2014 on five organic vegetable farms locating in different parts of Finland. In 2014, the catch crop experiment was esta ...

Influence of intercrop on plant growth and yield

Dane, S., Latvia Univ. of Agriculture et al. [2014]

The demand for healthy and reasonably cheap food is growing and governments are expanding policies to preserve soil fertility and nature. In addition, climatic conditions are changing. Arable lands are decreasing. Due to all of these changes food growers are looking for new growing technologies. A monographic method to tackle these problems has been used in this article. Intercropping is one o ...

Genetically modified crops become more widespread in agriculture in the EU. In order to prevent genetically modified organisms (GMO) from uncontrolled spreading in the natural environment, monitoring is required, which would allow us to predict and identify possible risks of spreading GMOs in commercial and organic fields. The processes taking place in rural areas require a precise information ...

In 1999-2003, the investigations were carried out in Juodkiskis study object of Water Management Institute of Lithuanian University of Agriculture. Study scheme is composed of three treatments: treatment I -slurry applied, treatment II - mineral fertilizers applied; treatment III - no fertilization. Test field is drained, drain spacing is 15 m; draining depth is 1.2 m. During the crop rotation ...

Fusarium head blight is one of the most important diseases in small grain cereals. This plant disease, which is caused by fungal species within the genus Fusarium, may have a negative influence on yield and grain quality. Mycotoxins produced by Fusarium species, accumulate in grains and may cause adverse health problems when consumed by human and animals. Seminar topics: 1) Plant – Fusarium i ...
