Title : FORMATION OF PANICLE BASIC ELEMENTS WITH TURKISH AND ITALIAN RICE CULTIVARS GROWN IN BULGARIA
Abstract : A two-factor field experiment was carried out in the Saedinenie region, Plovdiv municipality, Bulgaria in the period 2013 - 2015 following the split plot design with size of the reporting plot of 14 m2. Two Turkish (Osmanchik 97 and Gala) and four Italian cultivars (Lince, Cameo, Puma and Brio) were studied in the survey, grown on the larger plots (Factor A). Three foliar treatment products – Folur, Amalgerol and Litovit were set on the smaller plots (Factor B). The non-treated variant of each variety was used as control. The following basic panicle indices were studied: number of full and empty spikelet, panicle grain weight. All panicle elements were best developed in the favorable 2013 year. The Turkish cultivars formed the greatest number of grains with highest weight respectively, only under most favorable conditions (2013). The Italian cultivars, with the exception of Brio, behaved in a more adaptive manner throughout years with greater stress for the plants, especially during the flowering period (2014 and 2015). They formed grain from 2.5 to 2.9 g in 2014 and from 2.6 to 2.7 g in 2015. The application of foliar treatment products supported the plants to overcome stress and increased the grain weight.
