Effect of microbiological fertilizer and soil additive on yield of buckwheat (Fagopyrum esculentum Moench)under high altitude conditions

Abstract

Effect of microbiological fertilizer (Slavol) and soil additives (zeolite and hydrogel) on buckwheat (Fagopyrum esculentum Moench) yield was investigated in this paper. Trial was set up in the village of Radijevići, Serbia in agroecological conditions of mountain Zlatar (altitude 1,065 m) during a two-year period 2009 and 2010. A randomized complete block design with four replications was set up. In organic cropping system three combinations of microbiological fertilizer (Slavol) with zeolite and hydrogel were used prior to sowing. Different combinations of the microbiological fertilizer and the soil additives gave positive results especially in the second year of the trial. The best combination in organic cropping system was Slavol+hydrogel with foliar application of the microbiological fertilizer, which resulted in the greatest yield of buckwheat and this treatment can be recommended to producers. Buckwheat performed very well under limited conditions of acidic soil on high altitude in organic cropping system and it can be recommended as a very suitable crop for organic producers.

U ovom radu je ispitivan uticaj mikrobiološkog đubriva (Slavol) i oplemenjivača zemljišta (zeolita i hidrogela) na prinos heljde (Fagopyrum esculentum Moench). Ogled je postavljen u selu Radijevići u agroekološkim uslovima planine Zlatar na nadmorskoj visini od 1.065 m tokom dvogodišnjeg perioda 2009. i 2010. Ogled je postavljen po slučajnom blok sistemu u četiri ponavljanja. U organskom sistemu gajenja su primenjene tri kombinacije mikrobiološkog đubriva sa zeolitom i hidrogelom pre setve useva. Sve varijante đubrenja su dale pozitivne rezultate u odnosu na prinos, naročito u drugoj godini istraživanja. Najbolja kombinacija u organskom sistemu gajenja je bila varijanta Slavol+hydrogel sa folijarnom primenom mikrobiološkog đubriva Slavola, koja je dala i najveći prinos heljde. Gajenje heljde pod limitiranim uslovima kiselog zemljišta na većoj nadmorskoj visini u organskom sistemu gajenja se pokazalo opravdanim i može se preporučiti proizvođačima.
