AGRICULTURAL STUDIES ON WHEAT CROP
Mohamed Hamed Mohamed Koriem;
Abstract
The present investigation was carried out at the experimental Farm, Faculty of Agriculture, Kafr EI-Sheikh, Tanta University, Egypt, during 1999/2000 and 2000/2001 seasons to study the effect of seeding rates (250, 300 and 350 grainlm2) and nitrogen fertilizer rates (25, 50, 75 and 100 kg N/fed.) on growth, yield, yield components and grain protein percentage of two wheat cultivars (Gemmeiza 7 and Sakh:t69).
A split-split plot design was followed with four replication in both seasons, wheat cultivars distributed in the main plots, seeding rates assigned to the sub-plots and nitrogen rates allocated to the sub-sub plots. The results obtained could be summarized as follows:
1. Cultivars:
There are a significant differences between the two cultivars on all characters under study in both seasons. The results indicated that Gemmeiza 7 gave the highest values of dry matter accumulation at 85 and 100 day, dry matter distribution (leaves-stems-spike) at 85 and 100 days, plant height, CGR, number Qf spikeim\ leaf area, leaf area index (LA!), number of spikelets/spike, I 000-grain weight, grain yield/fed., harvest index and grain protein percentage in the two seasons. While, the lowest ones were obtained from Sakha 69. The first season was insignificant in dry matter distribution in form of leaves at 85 day, spike length, number of grain/spike and grain weight/spike. The second season was insignificant dry matter accumulation at 115 days, dry matter distribution in form of leaves at 85 days and straw yield/fed.
2. Effect of seeding rates:
1. Dry matter accumulation increase with increasing seeding rates in both seasons.
