Bulgaria. A relatively short organic history Organic Eprints
Apostolov, Stoylko; Heeb, Marlene.
Organic agriculture in Bulgaria has a relatively short history. The concept of organic agriculture was only introduced after the fall of the communist regime in 1990, when the process of land restitution started. Below is an account of developments over the following thirteen years and a report on the current status of organic agriculture in the country.

Директна сеитба със зелено торене Organic Eprints
Apostolov, Stoylko; Kirov, P.; Tihov, N..
Резултат - В началото растенията при директната сеитба имаха по-добро развитие. Но посева бе неизравнен (някои от растенията бяха във фаза 2-4 лист, други преминавали 8-ми лист). Мулчът задържа изпарението на влага. - При контролното поле в повърхностния почвен слой нямаше налична влага. Растенията са с леко завехнали и завити листа. Броят и растежът на растения е равномерен(фаза 3-4 лист). - Получените добиви (в свежа маса) са доста под очакваните. Добивът в контролното поле е по-висок: - контролно поле - 14,450 кг(от 0,6 ха), среден добив 24 083 кг/ха - тестово поле - 15,200 кг(от 0,7 ха), среден добив 21 714 кг/ха Практически препоръки - след прибиране на реколтата от предшественика(зърнени култури или рапица), през август направете обработка...

Comb harrow: efficient weed control in cereals Organic Eprints
Apostolov, Stoylko; Kirov, P; Tihov, N.
In the beginning, weeds with shallow roots were successfully eradicated by the harrow. Others (e.g., burdock and stork’s bill) were controlled to a certain extent. The results of FAO "Bioselena" show that the application of the comb harrow had a significant impact on the yield, with an increase of 12.7 % for wheat, 16.7 % for spelt and 23.4 % for ein-korn. The weeds decreased by 51.15 %, 58.14 % and 36.37 %, respectively. Practical recommendations • Drill winter cereals in rows with an increased sowing rate of 7-10 % compared to conventional cereal crops during the most appropriate period (September 25 to October 5 for Northern Bulgaria, 5 to 15 October for Southern Bulgaria). • When the crop is in the „3-leaf“ stage, control the emerging weeds with a...

Direct sowing with green manure Organic Eprints
Apostolov, Stoylko; Kirov, P.; Tihov, N..
Practical recommendations > After harvesting the main crop (cereals or rape), perform the stubble cultivation in August. > Sow the wheat‐legume mixture – winter forage peas and wheat (triticale) – by mid‐October. > At the end of May, grind the cover crop (mixture) with a roller crimper, then sow the corn with a direct sowing machine (drill). The mulch lying on the soil surface should dry before sowing. > The mulch reduces mineralization, so it might be better to use nitrogen fertilizer in the row.
