In Ethiopia, rice is an important cereal product. The lack of improved varieties that are suited to a particular area, however, it is the primary reason why the yield of this crop is constrained. This field experiment was carried out in Omorate, South Omo Zone, Southern Ethiopia, during the 2020 and...

Biochar is considered as a beneficial soil amendment for crop production. However, limited information is available on the effects of continuous applications of biochar on rice. In this study, a fixed field experiment was conducted in the early and late rice-growing seasons from 2015 to 2017. Grain...

Rice grain yield and quality declines are due to unsuitable temperatures from wide regions and various sowing dates. This study aimed to evaluate the effects of temperature on rice yield and quality at different phenological periods and obtain suitable temperatures for phenological periods in the Ya...

The current paper has presented the testing results of such ultra-early maturing maize hybrids of French breeding with different FAOs, as ‘Zeta 102’ (FAO – 115), ‘Zeta 140 S’ (FAO – 140), ‘Lazuliya’ (FAO – 170) in 2019 and 2020. The phenological study has shown that at the beginning of the vegetatio...

Controlling of genetical parameters on grain yield and its components were study in six generation (P1,P2,F1,F2,B1 and B2) for two crosses of hexaploid wheat, Triticum aestivum L. (Iba-99 x Reyna-27) and (Abochareeb-3 x Jawaher-20) to estimate: gene action parameters, components of genetic variance...

To evaluate yield, yield components and remobilization of assimilates of wheat genotypes under normal irrigated and water deficit conditions, an experiment was conducted in a randomized complete block design with three replications in two growing seasons. The results showed that the highest yields...

Improving grain yield (GY) and reducing grain moisture (GM) are urgent demands for directly harvesting kernels with combine harvesters in maize production. GY and GM are both related to leaf, stem and root characteristics, but the relationships are not fully understood. To better understand these re...

This study was conducted to investigate the effect of different foliar microbial fertilizer applications on yield and yield components of some cowpea (Vigna unguiculata L. Walp) cultivars (Akkız-86 and Karagöz-86). The research was conducted in 2022 growing season under Kayseri ecological conditions...

Intercropping is an eco-friendly agricultural practice that can lead to increased productivity and improved resource efficiency. This two-year field study (2022–2023 and 2023–2024) aimed to evaluate the yield and quality (protein content) of lentil when intercropping with bread wheat (Yekora) and oa...

Adopting Just and Pope (1978, 1979) style yield functions, this paper proposes a method to analyze the impacts of regional climate change on grain production in China. We find that changes in climate will affect grain production in North and South China differently. Specifically, it emerges that a 1...

Nitrogen (N) is a key growth and yield-limiting factor in cultivated rice areas. This study has been conducted to evaluate the effects of different conditions of N application on rice yield and yield components (Shiroudi cultivar) in Babol (Mazandaran, Iran) during the 2015- 2016 season. A factorial...
