Effective microorganisms (EM) comprise a mixture of live natural cultures of microorganisms isolated from fertile soils that are used to improve crop production. The purpose was to assess the influence of EM on the growth and nutrient content of leaf celery transplants. Two treatments were compared: 1) EM treatment comprised of seed soaking in EM 1:500 solution, sowing in EM treated peat and w ...

Vermicompost produced by earthworms is rich in macro- and micronutrients, vitamins and growth hormones, which are all needed for successful plant growth. The influence of vermicompost based growth substrates on basil (Ocimum basilicum L.) growth and nutrient content was assessed. Treatments were: 1. 30% vermicompost, peat, sand, dolomite stone; 2. 25% vermicompost, peat, gravel, perlite; 3. 25 ...

During drought chemical elements in a dry fertilizer go into solution in the soil with difficulty and the nutrients are less available to the plant. Foliar fertilization with Tecamin flower®, could compensate for nutrient deficiency due to water deficit. This study was designed to observe the effects of different application rates of foliar application of Tecamin flower® on growth, yield and f ...
