Abstract
Four experiments were carried out. Two experiments were grown in each of Ismailia and Tag El-Ezz Agricultural Research Station in 1997/1998 and 1998/1999 growing seasons. Ismailia and Tag El-Ezz experimental soils representing a sandy soil with drought stress conditions and salt affected clay soil.
Two triticale varieties (Juan and the new line T. line 1) and the commercial bread wheat cultivar Sids 1 were used. The varieties were grown in split-split plot in RCB design under three nitrogen levels (60, 90 and 120 kg N/faddan) with three seeding rates (200, 300 and 400 seeds/m2). Data of grain yield and yield components were recorded from all the experiments.
Analysis of variance indicated that the mean grain yield in sandy soil (10.20 ardab/ faddan) was higher than that in saline soil (7.24 ardab/faddan). That was true with number of spikes/m2 and 1000-kernel weight. The new triticale “T. line 1” significantly outyielded the other varieties and produced 11.17 ardab/faddan in sandy soil. No significant differences were observed between varieties in saline soil.
In sandy soil, grain yield responded up to 90 kg N/faddan and recorded 10.74 ardab/ faddan, while in saline soil the nitrogen level of 60 kg/faddan seems to be adequate, since it gave the higher grain yield of 7.86 ardab/faddan. Nitrogen level had the same significant effect on number of grains/spike and with insignificant effect on either number of spikes/m2 or 1000-kernel weight, in both soils.
Seeding rate had a significant effect on grain yield and yield components in sandy soil only. The higher seeding rate (400 seeds/m2) produced higher grain yield (11.03 ardab/faddan). The same trend was observed in the three yield components.
Under sandy soil conditions, in Ismailia, the nitrogen level of 60kg N/faddan was enough for Juan to produce its highest grain yield, while T. Line 1 gave the highest grain yield with 90 kg N/faddan. Sids 1 responded up to 120 kg N/faddan.
Generally, the highest grain yield produced when T. Line 1 was grown under 90 kg N/faddan using 400 grains/m2.
