Abstract:

Sowing methods and seeding rate play an important role in the placement of seed at proper depth and stand establishment of the growing crop which ultimately affects crop growth and productivity. This study was conducted for 2 seasons to establish optimal sowing method and seeding rate for bread wheat (Triticum aestivum L.) in sandy-loam soil. The study aimed at achieving high yield and profit. A field experiment was conducted using a randomized complete block in split plot design with three planting techniques (hilling in ridges, drilling in rows and broadcasting) and four seeding rates (100, 125, 150 and 175 kg ha-1) as the main plot and split plot, respectively. Results revealed that all yield and yield parameters were significantly affected by the sowing method and seed rate, while grain protein content was non-significant by these factors. The interaction of sowing method and seed rate significantly affected the number of effective tillers m-2, weight of grains spike-1, grain and straw yields ha-1 and harvest index. Wheat sown by drilling method at the seed rate 150 kg ha-1 gave the highest values of grain and straw yields ha-1 and harvest index and this treatment was found to be most economical. Based on these results, it is recommended to sow 150 kg ha-1 seeds by using drill method for planting bread wheat Giza 168 cv under similar soil and climatic conditions. Correlation coefficients analyses revealed positive significant relationships between grain yield and plant height, effective tillers m-2, grain number spike-1, straw yield and harvest index.
