| Abstract:
The two-year study was conducted to compare the effect of inter-row distance: 0.7 m; 0.8 m and 0.9 m on growth and yield of different potato (Solanum tuberosum L.) cultivars: Ostara, Desiree, Frisia, Asterix (plant density 40.816 plants ha-1) and Agria, Bintje, Russet Burbank, Shepody (35.714 plants ha-1). Field experiment was carried out on the slightly calcareous chernozem in Zemun polje to evaluate the effects of examined factors on processable and total tuber yield of potatoes. The shape of plant vegetation space influenced different soil moisture and temperature regime which significantly affected plant height, number of stems, and plant biomass. According to analysis of variance for tubers number, shape and size (the tubers were graded into the following categories: small < 70g pear shaped, knobby and processable), significant influence of investigated factors and of their interactions were found. The results of this study indicate that, in semi-arid conditions in Yugoslavia even with irrigation the incidence of second growth were caused not only by moisture stress, but due to a seasonal conditions such as soil and air temperatures. | |
