The Effects of Planting Date and Cutting Time on Teosinte Productivity Under Soil Salinity

Abstract

During the summers of 2019 and 2020, two field experiments were conducted at El-Serw Agriculture Research Station, in Damietta Governorate. Teosinte seeds were planted on three different dates (15 th March, 15 th April, and 15 th May), and subjected three cutting time of 40, 50, and 60 days in two different salinity soil sites (low and medium salinity depending on dsm -1 ). The first sowing date and cutting at 60 days in low saline levels led to the heaviest overall fresh and dry weights throughout both seasons. In both seasons, the first sowing date and the first cutting time at the medium salt levels resulted in the lowest mean of total fresh and dry weights. In both seasons, the highest data of fruit instances was observed from the second sowing and cutting time at 60 days under the first level of salinity. The first and second sowing dates under the three managements of cutting under two soil salinity levels showed no significant differences. Under the first soil salinity, the maximum mean of 100 grains weight was reported from the third sowing date and cutting at 60 days. During the first season, the third sowing date and cutting at 50 days under low salinity conditions resulted in the highest seed weight/fed, whereas in the second season, the second sowing date at 50 days under low salinity levels resulted in the highest seed weight/fed. Under medium salinity soil, the lowest seed weight/fed values were reported from the first sowing date and cutting at 40 days.

Assessing of Some Summer Forage Crops to Infection by Common Smut and Downy Mildew Diseases for Forage and Silage Production

“…Data in Table 4 showed that piper black had the highest fresh and dry forage yield at the three cuts in the two seasons and it's combined. Piper black had the highest fresh and dry forage yield at the three cuts in the two seasons and its combined which had (26.4,22.3,17.1 and 65.7kg/plot) for fresh yield for combined data, while had 5.3,2.8,2.5 and 10.59 for dry yield ,respectively [6,23,24,25]. For combined data of total yield millet Shandawal 1 were 46.7 kg/plot, and 7.8 kg/plot ,while Saudia Arabia Millet gave 31.3 and 4.9 kg/plot, for total fresh and dry forage yields, respectively, it mean that Shandawal 1 surpass Saudia Arabia by 49.2 and 59.2% for fresh and dry yield, where Saudia Arabia Millet had 12.8 , 10.5, 80 and 31.3 kg/plot for fresh yield in first ,second, third and total yield ,respectively [26].…”

Maximizing Land Use Efficiency by Intercropping Some Summer Forage Crops With Maize

“…pearl millet (Pennisetum glaucum, L.), sudan grass (Sorghum sudanense, L.) and teosinte (Euchlaena maxicana, L.) are the most popular cereal fodder crop belonging to the Poaceae family. They are drought and heat tolerant and has a considerable ability to grow in sandy, infertile and saline soils under arid, hot and dry climates in the region as reported by Jukanti et al(2016) and Salem (2020) for millet Abo-Zeid et al (2017) for sudan grass and Devkota et al (2015) and Seadh et al (2022) for teosinte.…”
