Teosinte (Euchlaena mexicana L.) is a popular herbage crop in Nepal. Although farmers produce teosinte seeds, management for maximizing seed yield unknown. A study was undertaken to investigate order explore the production potential of yield. There were four different sowing dates (30 March, 30 April, May and June), rates (20, 40, 60 80 kgha?1) three cuttings (nil, once at 45 days after (DAS), ...

Heterosis is the groundwork for developing a good economically viable hybrid maize variety. Evaluation of Maize test crosses was carried out during 2019 main cropping season at research field Haro Sabu Agricultural Research Center West Oromia, Ethiopia. The objective study to identify direction and magnitude standard heterosis in mid-land hybrids grain yield attributing agronomic traits. Sevent...

High temperature reduces the pollen viability and silk receptivity of corn resulting in poor seed set and reduced yield. Continuously increasing temperature and less frequency and distribution of rainfall coupled with usual canal–closure particularly in Pakistan have significantly been decreasing the grain yield. This problem could be overcome by developing heat tolerant maize hybrids. For this...

This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5). Data w...

The United States is the largest producer of maize in the world. Maize-soybean is the most prominent crop rotation in the Midwestern United States. Glyphosate-resistant volunteer maize is a problem weed not only in soybean, but also in continuous maize or sugarbeet rotations. Storm damage, harvesting problems, poor stalk quality, and insect damage, among other factors, can lead to kernel and ea...

Chromatographically distinct isoacceptors of leucyl-tRNA from mature bean leaves were all observed to hybridize with bean chloroplast and nuclear DNA in a ratio similar to that exhibited by the unfractionated leucyl-tRNA. Under the same hybridization conditions, maize tRNA failed to form a stable hybrid with bean DNA, and levels of hybridization between bean-leaf leucyl-tRNA and nuclear or chlo...

ABSTRACT Measures of epistasis in maize hybrids have been estimated by (i) triple-test crosses, (ii) making comparisons Certain maize (Zea mays L.) inbred lines are more successful than of single, three-way, and double cross hybrids, or (iii) others in forming elite hybrids. This study was conducted to determine measuring variance components (Hallauer and Miwhether epistatic interactions play a...

Quantification of the Nitrogen (N)-supplying capacity of organic manures provides an important insight into more effective N management practices. The aims of this study were to determine the potential N mineralization of cow manure (CM), poultry manure (PM), urea fertilizer (UF) and the combined use of cow manure + urea fertilizer (CM + UF) for silage maize (Zea mays L.) in a calcareous so...

Achieving grain supply security with limited arable land is a major challenge in the twenty-first century, owing to the changing climate and increasing global population. Maize plays an increasingly vital role in global grain production. As a C4 plant, maize has a high yield potential. Maize is predicted to become the number one cereal in the world by 2020. However, maize production has plateau...
