Introduction: To reduce food insecurity, crop production will have to be doubled, and produced in more environmentally sustainable ways. This can be achieved by expanding the area of crop production, increasing per-hectare yield, and improving crop quality. Furthermore, during the second half of the past century, the rise in per-hectare crop productivity was due to improved or high-yield potential. Works in the late 1980s demonstrated that yields could be raised two to three-fold by using available improved varieties and appropriate agronomic techniques. However, these findings need to be refined, improved, and tested for local climatic, soil, and crop conditions.
Materials and methods: To develop and manage for new pearl millet line in the summer, this research was performed in Gomishan and Minodasht. Experiments were conducted on three levels for the comparison of two new pearl millet lines (Pennisetum americanum) with Pishahang in Golestan province fields. The number of planting lines was 60 liens with a length of 66.66 meters and 50 cm intervals. For measurements of plant height, number of tillers, stem diameter, the number of nodes, and so on, 10 bushes were randomly harvested by using quadrate. Ultimately, the total surface area based on project protocol was harvested as well.
Results: The results of comparing yield and morphologic parameters of two new Pearl millet lines (Pennisetum americanum) and Pishahang showed that fresh forage and dry forage production of KPM1, 25.35% and 27.23% respectively were greater compared to Pishahang variety. KPM4 line had, 34.76% and 38.24% respectively priority more than this compared to check treatment. Meanwhile, grain yield production of new Pearl millet lines compared to Pishahang was not significant. In addition, the perfect morphological parameters also got from the new Pearl millet line it meant the new millet line bushes grew better and produced good yield components and the benefit of changing agronomical treats would appear at high forage yielding without negative effect on grain yield. Accumulation of environmental potentials such as light led to the extension of the leaf area, improvement at plant height, number of leaves, number of nodes, panicle length, and stem diameter. It also increased yield and yield components parameters of pearl millet lines compared to check treatment similar to this research reported also by many researchers.
Conclusion: Overall findings showed that; KPM4 line had better performance compared to KPM1 and the fresh forage and dry forage production in KPM4 and KPM1 were greater than Pishahang variety. It might be concluded that using new pearl millet line seeds in summer could lead to a higher yield and surface area. |
