Abstract
In the period 2004–2006 in the ‘Maritsa’ Vegetable Crops Research Institute ‐ Plovdiv, trial field cultures of early potatoes (“Nadejda”) were performed under polypropylene (PP) cover ‐ Lutrasil “Extra”. The influence of the PP covers on the growth and productivity of early potato plants was investigated.
It was established that polypropylene cover have a beneficial effect on the micro-climatic conditions, speeds up the development of the culture from 4 to 7 days and increases the productivity of potato plants.
When growing on furrows and using PP cover, it was observed that on the 60th day from germination of the plants the yield received was greater on average by 29.7% in comparison with the control variant.
On the 75th day from plant germination, the influence of polypropylene cover is less prominent and the average yield is 16.3% greater in comparison to the control variant.
