ABSTRACT



In 2004-2004 studies were conducted with the use of fertigation in a greenhouse concerning the photosynthetic activity of the leaves, water potential and the yielding of tomato cv. ‘Cunero F1’ cultivated on different substrates. The plants grew in rockwool mats with the volume of 15 dm3 and on mats of analogous dimensions prepared from the chaff of rye straw, rye straw + peat (3:1), wheat straw + bark (3:1). Two plants were grown in each mat in the period between February and October, and they were grown for 22-23 clusters. The obtained results pointed out that the value of the analyzed indexes of chlorophyll fluorescence (Fo, Fm, Fv/Fm) and the gas exchange of the leaves (gs, E, P, Ci) in plants on rockwool and on substrates prepared on the basis of rye and wheat straw did not differ in a statistically significant way. Water potential in the leaves and the fruit yield from plants cultivated on the used substrates were also similar. The authors are of the opinion that in the conditions of the application of fertigation, the cultivation substrates obtained from rye or wheat straw chaff and their mixtures with other organic materials make it possible to obtain the yield of tomato fruits on the level equal to that on rockwool.

Key words: greenhouse tomato, substrates, chlorophyll fluorescence, gas exchange, water potential, yield.
