Nine bread wheat early maturing promising lines and three local cultivars were evaluated at Mallawy Agric. Res. Stations, ARC, Egypt, for the two successive growing seasons of 2018/2019 and 2019/2020 under the two sowing dates, the recommended (SD1:30 th November) and the late sowing date (SD2:30 th December). A split-plot arrangement with three replicates was used in each season. The aim of this study was to select the best genotypes for early maturity and higher grain yield. The results showed significant differences among genotypes for all studied traits in the optimum sowing date (SD1) compared to late sowing date (SD2). The optimum sowing date (S1) produced the highest values for all studied traits in both seasons, while the late sowing date (S2) was recorded the earlier plants for heading and maturity dates. The studied genotypes differences significantly in all estimated traits, lines 1 and 2 had the earliest genotypes for heading days, while Giza 171 and line 8 were the latest one for this trait. On the other hand, lines 9 and 4 were the earliest genotypes for maturity date, while the latest one was recorded for Giza 171. Line 5 surpassed all the other genotypes in grain yield (28.31 and 23.17 ard. fed -1 ) in the first and second seasons, respectively and it is appeared to be more tolerant to late sowing date as well as heat stress. The interaction (SD x G) had a significant effect on most studied traits. Lines 9 and 6 were the earliest genotypes for maturity when sown on 30 Nov. also, lines 9 and 4 were the earliest genotypes when sown on 30 Dec. The highest grain yield was obtained from line 4 followed by line 5 when sown on 30 Nov. and line 5 had the highest grain yield when sown on 30 Dec. in the first season. While, in the second season, lines 5 and 8 recorded the highest grain yield when sown on 30 Nov. and 30 Dec. respectively. Line 5 is suitable for planting in a wide range of planting dates (from 30 th Nov. to 30 th Dec.). Moreover, it is early maturing and can be recommended for late sowing (30 th Dec.). Therefore, the results of the present study confirmed that lines 4, 5, 7 and 6 were superior over the other genotypes in producing the earliest maturity date and higher grain yield and can be used, in future, in bread wheat breeding programs for the development of wheat cultivars for high temperature stress condition at the terminal growth stage.

“…Grain yield in the two seasons was the most affected character by late sowing date. Similar findings were obtained by Ali et al, 2010 andAcharya et al, 2017. Data in table 10 showed the reaction of the new evaluated lines to the three rusts, leaf rust (LR), yellow rust (YR) and stem rust (SR). Rusts estimated were used as criteria todifferentiate between lines.…”

Five parents and their derived F5 families (12 families) and new check variety Sakha 95 were evaluated under two sowing dates, optimum sowing (OS) and late sowing (LS) dates for earliness, yield and yield components. The study was laid out in RCBD experiment in four replications in the experimental farm at Sakha Research Station, KafrElsheikh Governorate. The analysis of variance showed the presence of highly significant differences between years, sowing dates and genotypes under study. Interactions between all studied characteristics were also significant except for No. of kernels spike-1 and No. of spikes m-2. Reductions in grain yield and its components were observed in the first season compared to the second season due to climatic conditions. Likewise, the values of the characteristics at the late planting date were less than the ones at the recommended date due to the effect of high temperatures at the end of the season. For the characteristics of the resistance to the rust, three families showed resistance to the three rusts in the two seasons, as well as on the two sowing dates. Therefore, these three families can be used in breeding for rust resistance.Family number 12 was the most tolerant to high temperatures at the end of the season after the comparative cultivar Sakha 95 and recorded the lowest percentage of decline in yield as a result of late planting, so it is recommended to plant them in the case of late planting.

Intensive tillage with no crop residue after rice harvest in conventional wheat cultivation increases the turn around time, delays sowing and affects the yield. A field experiment was carried out to assess the effect of sowing dates, establishment methods and mulching and their interaction on growth, productivity and profitability of spring wheat at agronomy farm of AFU, Rampur Chitwan, Nepal from November 2020 to April 2021. The experiment was laid out in strip-split plot design, with three dates of sowing (20th November, 5th December and 20th December) in vertical plots, two establishment methods (Zero tillage and Conventional tillage) in horizontal plots and two levels of mulching (0 t ha-1 and 5 t ha-1 of rice straw mulch) in sub-plots and replicated thrice with Vijay as test variety. Data regarding the phenology, growth parameters, yield attributes and yield were recorded, analyzed and presented. The research results revealed that date of sowing and mulching significantly influenced phenology, growth, yield attributes, yield and their interactions. The higher grain yield was obtained in 5th December as well as 20th November sowing in conventional tillage with mulch (4511.49 & 4492.12 kg ha-1 respectively). These grain yields were statistically at par with 5th December and 20th November sowing in zero tillage with mulch (4363.74 & 4129.97 kg ha-1 respectively). Net return and B:C ratio were significantly higher on 5th December and 20th November sowing with mulch in zero tillage than 20th December sowing in conventional tillage without mulch. Int. J. Appl. Sci. Biotechnol. Vol 10(4): 237-244.
