The impact of reduced tillage on the morphological and physiological parameters of soybean

The scope of this research was to determine impact of different soil tillage on the morphological parameters (number of branch, pod weight and stem length) and physiological parameters (chlorophyll a, chlorophyll b, chlorophyll a+b and carotenoids) of soybean. The research for soybean has been conducted at the North-eastern Croatia chernozem soil type during the period of 2001/2002–2002/2003, with following continuous soil tillage treatments: CT – conventional soil tillage, based on mouldboard ploughing ; DH – multiple pass diskharrowing ; and NT – no-tillage. The influence of Year was significant for the production of chlorophyll b and carotenoids, while the soil treatment had significant effect on the concentration of chlorophyll (a + b) and chlorophyll b. The interaction Year x Tillage proved to be significant only for concentration chlorophyll b and carotenoids. Agroclimatic conditions significantly affected all the morphological characteristics of soybean, while the effect of tillage was not statistically significant.
