The Influence of Precursory Plant on Winter Wheat Production from Long-Term Experiences

Abstract

Winter wheat is strongly influenced by the precursory plant. The rotational experiences established in the experimental fields of ARDS Turda, started in 1967, and are installed as follows: winter wheat after soybean, soybean, potatoes, winter wheat after maize and maize. In this paper we studied the influence of precursory plant, as a factor which influences winter wheat productivity. Our results showed that the precursory plant has a distinguish effect on winter wheat productivity. We registered yields higher with 273 kg/ha when winter wheat was cultivated after soybean compared to the yields achieved when winter wheat was cultivated after maize (control variant). Indubitable fertilization had the greatest contribution to these results but the effect of precursory plant is also significant.

Varietal Structure of Rice Crops in the Krasnoarmeisky District of Krasnodar Region: Analysis and Recommendations

“…Thus, for the dynamic development of the industry through science-based variety substitution (that is, replacing the existing varieties with more productive and resistant to biotic and abiotic stressors ones), agroecological variety tests are conducted. They are aimed at demonstrating new varieties, developing varietal agricultural equipment and making recommendations for varietal complexes , Ladatko MA 2019, Wang Zhu et al 2016, Nascente AS, Stone LА 2018, Khanam Shakhina et al 2016, Fageria NK 2015, Tari DB et al 2017, Deac et al 2015.…”
