FIELD PEA (PISUM SATIVUM L.) BIOMASS PRODUCTION DEPENDED ON SEED AGE AND AGROECOLOGICAL GROWTH CONDITIONS

Abstract

Influence of weather conditions and seed age on fresh and dry biomass production, field germination, seed yield and 1000 seed weight of field pea were investigated in field trials during two years at two locations of East Croatia (Osijek and Vinkovci). Seed of „Timo“ cultivar 9 and 21 month old was used for sowing. In the investigation of the years influence, significantly higher (p=0.01) average green mass yield (57,035 t/ha), dry matter yield (9.796 t/ha) and 1000 seed weight (129.7 g) was found in the first year of the investigation. On the average for years, significantly higher field germination (87.0%) and seed yield (2.173 t/ha) at p=0.01, and green mass yield (55.728 t/ha) and 1000 seed weight (130.1 g) at p=0.05 were found at location Osijek. Seed of 21 month old had higher (p=0.01) average green mass yield (64.376 t/ha), dry matter yield (10.934 t/ha) and 1000 seed weight (134 g) but significantly lower field germination (76.4%) at location Vinkovci in the investigation of seed age and location influences during 2005 year..
