Abstract
A field experiment was conducted on rendzina soil in the years 2010-2012. The seeds of two linseed cultivars (Szafir and Oliwin) were sown at row spacing of 15 cm and 25 cm. Three agrotechnical levels in different nitrogen doses and with or without application of herbicides were used. The objective of the study was to evaluate the effect of row spacing on yield, seed protein and oil content of two linseed cultivars grown under different conditions of mineral fertilization and chemical weed control. Results showed that cv. Szafir was characterized by significantly higher seed yield (on average by 20.2%) and protein content (by 2.6%) while cv. Oliwin had higher content of oil (by 4.9%). Intensive technology of cultivation (80 kg N/ha, Linurex 50 WP, Fusilade Forte 150 EC, Glean 75 WP), compared to the economical technology (40 kg N/ha, without herbicides), significantly increased the seed yield of both linseed cultivars (on average by 80-102%). This was due to higher plant density, higher number of branches, and higher number of capsules per plant. The intensive technology of cultivation had a beneficial effect on the content of α-linolenic acid in linseed seed.
