The Influence of Soil Tillage System on Changes in Gas Exchange Parameters of Pisum sativum L.

A field experiment was carried out in 2017–2019 as a split-plot design with four replicates at the Agricultural Experimental Station Grabów, Poland. The aim of study to compare gas exchange parameters pea depending on use different soil tillage systems. Physiological plant as: net photosynthetic rate (PN), transpiration (E), stomatal conductance (gs), intercellular CO2 concentration (Ci) and relative chlorophyll content were measured three developmental stages. have showed that all affected by system soil. Net significantly lower treatments, where simplified-tillage applied. Pea grown plough (CT) generally higher photosynthesis compared peas reduced no-tillage systems, but this dependent development stage weather conditions prevailing given year. highest under cultivation methods found system, regardless legumes. values determination coefficients positive relationship between seed yield tested years research. also SPAD index CT irrespectively stage.
