We report on a study of mid-rotation weed control and nutrient management in Eucalyptus pellita plantations in South Sumatra. The study was established at two contrasting sites (representing high and ...
Potato yields and infestation by P. infestans are related to the supply of potassium. Potassium was applied as soil fertilisation combined with split foliar applications or only as split foliar treat...
We examined the relationships between a number of sperm characteristics (motility, concentration and pH) and sperm fertility (egg fertilisation and hatching rate) in 10 mature females and four mature ...
We evaluated the potential of crushed amphibolite and artificial slow-release N-P-K-Mg fertiliser to stimulate the survival, growth and nutrition of Norway spruce planted on an acidified air-polluted ...
Our research was realised on spring barley and winter wheat in Nitra-Dolná Malanta during 2004–2006. We found that the total occurrence of the pests had decreasing tendency. The flea beetle (Phyllot...
The effect of fertilisation with fermented pig slurry on the quantitative and qualitative parameters of two kinds of tomatoes was assessed by means of pot trials. These trials were carried out betwe...
Yellowing of Norway spruce is a relatively common problem in many regions of the Czech Republic. At some places, it is also connected with forest decline. This unfavourable phenomenon is initiated by ...
The objective of this research is to study the effect of two measures (fruit thinning and additional fertilisation – 222 kg calcium nitrate/hectare) compensating the negative influence of weeds (yield...
The study was conducted on the basis of a multiannual static field experiment established in 1979. It was conducted in the 3-year simplified rotation system: potato – winter rye – winter rye. The stu...
The paper presents the results of two experiments which covered the relationships between the tillage method (ploughing and non-plough tillage) and the level of nitrogen fertilisation (50 and 150 kg N...
Over 1995-1997 a two-factor experiment was carried out which aimed at defining whether and, if so, to what extent magnesium fertilisation affects the content of organic acids and potato tuber blacken...
The objective of the study was to evaluate the productivity of five fodder crops (white mustard, radish, winter rape, sunflower and tansy phacelia) cultivated as a stubble intercrop after winter wheat...
The aim of the present studies carried out over 1994-1998 was to define the effect of multi-year fertilisation with straw + NPK, NPK only, manure only, manure with: PK, NK, NP, NPK, NPK + Ca and no fe...
Nitrogen fertilisation is one of the most effective yield-increasing factors but also one of the most critical items of cereal production costs. The aim of the present study was an attempt at definin...
The aim of the studies carried out in 1997-2002 was a comparison of weed infestation and spring wheat yielding when organic and conventional fertilisation was applied. It was observed that fertilisati...
