“…The SD3 had higher cumulative Srad and CHU compared to SD1 and SD2; however, the cumulative precipitation amount received during SD3 was lower compared to SD1 and SD2 and this could have contributed to lower grain yield. The GDDs decreased with delay in SD and this study agrees with the findings of Dahmardeh (2012).…”

A study was conducted at the Zambia Agriculture Research Institute (ZARI), Central Research Station, Mount Makulu (latitude: 15.550° S, longitude: 28.250° E, altitude: 1213 m), Zambia to investigate the effects of sowing date (SD), maize (Zea mays L.) cultivars and 3 N fertilizer rates on yield and yield components. Maize cultivars were planted on 12th December, 2016 (SD1), 26th December, 2016 (SD2) and 9th January, 2017 (SD3). A split-split plot design was setup with SD, maize cultivars (ZMS 606, PHB 30G19 and PHB 30B50) and nitrogen rate (67.20, 134.40 and 201.60 kg N ha-1) as the main-plot, subplot and sub-subplot, respectively. The rainfall, solar radiation (Srad) and mean temperature at the experimental site during the 2016/2017 season were 930.17 mm, 18.93 MJ m-2 day-1 and 21.83°C, respectively. Analysis of variance for Split-split plot design was used to analyze maize yield and yield components and means separated at p≤5 using Tukey's Tests. Results showed that the treatment effect of sowing date and cultivar was significant on biomass yield, harvest index, 100-grain weight, seed number m-2 , cob length, and width. Seed number m-2 , 100-grain weight, grain and biomass yield reduced with delay in sowing date. The reduction in grain yield from SD1-SD2 (1.91 t ha-1), SD1-SD3 (2.90 t ha-1) and SD2-SD3 (0.99 t ha-1) were 21.04, 31.83 and 13.83%, respectively. Therefore, it was concluded that maize grain yield and yield components are affected by SD, cultivar and N. Farmers could enhance maize yield by manipulating sowing date, cultivar selection and N as the most limiting nutrient in agriculture production systems.

“…Seed weights are components of yield where its contribution strongly influenced by the environment (Johnson et al, 1996). In this connection, significant effect of sowing time on HSW where the higher HSW was produced by early sown maize plants also documented by Dahmardeh (2012). Similarly, Pettigrew (2002) reported that early planted cotton recorded higher lint (about 8%), number of bolls m -2 and lint percentage significantly than did cotton in the normal planting.…”

Growth and development of cotton is influenced by several environmental factors such as fertility and biology of soil, change in temperature, amount and distribution of rainfall and carbon dioxide concentration which are attributes of climate change. A field experiment was conducted to study the contribution of weather variables for the total variation in yield and yield components during reproductive phenophase of cotton (square initiation to boll opening) during 2013-14 and 2014-15 kharif season. The experiment was set out with three sowing time (24, 26 and 28 standard week) as main plot, three deficit irrigation schedules (0.8 IW/CPE, 0.6 IW/CPE and 0.4 IW/CPE) and rainfed as sub plot in split plot design. The result indicated that significant effect of sowing time on yield and yield components of cotton where maximum number of bolls per plant, boll weight, hundred seed weight, ginning percent, and seed cotton yield attained on early sown cotton. Weather variables showed significant correlation with yield and yield components. Results of regression analysis suggested that weather variables such as maximum temperature, mean temperature, relative humidity I and relative humidity II were found to be influential and accounted for over 90% of total variation in seed cotton yield and yield components during the reproductive phenophase.

“…Delayed sowing (6 July) increased fresh ear yield and fresh kernel yield compared with 5 June in 2010 and 2011, respectively. Dahmardeh (2012) reported that seed yields generally increased with later planting dates with the lowest yield from the earliest planting date. Low yields from the first and second sowing dates were likely associated with the detrimental effects of high temperatures and low humidity on pollination, fertilization, and grain filling.…”

The high vulnerability of sweet corn (Zea mays L. var. saccharata) to weed competition and the urgent reduction of the dependence on chemical herbicides are major challenges facing the agricultural community. To investigate the effects of plastic mulches on weed control and yields in sweet corn under different sowing dates, a 2-year experiment was conducted at Varamin, Iran, in 2010 and 2011. The mulch treatments included black plastic mulch, semitransparent biodegradable mulch, an unmulched weeded control, and an unmulched unweeded control. The sowing dates were 5 June, 20 June, and 6 July. Results revealed that delayed sowing (6 July) reduced weed dry weight by 51% and 41% compared with the 5 June sowing date in 2010 and 2011, respectively, without reducing crop yield. The black plastic mulch treatment had the lowest weed biomass. The sowing date × mulch interactions on kernel number per ear, length of ear, percentage of unfilled ear tip, and yield of sweet corn were statistically significant (P < 0.01) in both years. The maximum kernel number per ear (535) and the highest fresh ear yield (24,684 kg·ha−1) in 2010 were obtained on the 6 July sowing date under biodegradable mulch. The plants sown on 6 July produced the highest fresh kernel yield with the black plastic mulch (12,893 kg·ha−1) and unmulched weeded control (11,777 kg·ha−1) in 2010 and 2011, respectively. The highest percentage of unfilled ear tips in both years was observed in the unmulched unweeded plots sown on 5 June. According to our findings, to suppress the weeds and avoid the sweet corn yield loss in such a hot summer that we had, using the black plastic mulch and delayed sowing are recommended.
