on maize yield, in the period 2019, 2020. The systems MD (6430 kg/ha) and NT (5421 kg/ha) negatively influence the yield … of maize, the differences from the control (SC 8779 kg/ha) being between 2260 kg/ha - 3239 kg/ha. The yield average … with 2.5 t/ha vegetable residues + 350 kg/ha NPK proved to be more efficient in obtained the yield, compared to the …

The purpose of this paper is to evaluate the soybean yield obtained from the application of the additional … very significant yields of over 120 kg/ha. The Mălina soybean variety achieved an average yield of 2706 kg/ha, in the … thermal and pluviometric regime is an important factor in determining the yield of a crop, in 2015 was obtained an average …

how recent drought exposure, drought risk, and other climatic features have influenced adoption of DT corn--a water … risk--rather than short-run drought exposure in recent prior years--led to increased adoption of DT corn varieties in 2016 …. Farmers are more likely to plant DT corn on highly erodible land and less likely to irrigate such varieties, consistent with …

The purpose of this work is to evaluate the corn production obtained following the change of the sowing date. In the … (Season I - 6ºC in soil; Season II - 8ºC in soil; Season III - 10ºC in soil); corn hybrids (Turda 248 - control; Turda 165 … being the decisive factor in the realization of these productions. All analyzed hybrids recorded a higher average yield when …

effect of conservation tillage on crop yield is a subject of continued concern amongst farmers who have not adopted the … practice. Previous empirical research on the yield performance of conservation tillage is largely limited to field trials …, while observational studies remain scant. This article estimates the effects of conservation tillage on county average corn …

model results indicated that the agronomic innovation packages could improve maize yield by 1 t ha-1 to 2.3 t ha-1 in the … studied countries. The magnitude of the yield improvement is country and package specific. The largest maize yield … packages showed the highest maize yield. We conclude that it is vital to combine the agronomic packages to fill the gap between …

The purpose of this paper is to evaluate the soybean yield obtained from the application of the minimum tillage system … conservative tillage system, there is a slight decrease in yield compared to the classical tillage system, and between the two …
