Comparison between wheat conventional planting methods and raised beds method using three seeding rates under Upper Egypt conditions

Abstract

Wheat grain yield can be improved by using appropriate planting method with a balanced seeding rate. The experiment was conducted during the two successive growing seasons, i.e. 2019/2020 and 2020/2021 at Almatana Agricultural Research Station, Agricultural Research Center, Egypt. The experiment was grown in a split plot arrangement in randomized complete block design with three replications, where the main plots were allocated to planting methods and seeding rates were represented in the split plots. The objective was to study the impact of three planting methods, i.e., broadcasting, drilling (conventional) and raised beds using three seeding rates, i.e., 35, 45 and 60 kg fed -1 (fed -1 = 4200 m 2 ) on yield and yield components of wheat cultivar Misr3. Results showed that grain yield and its components traits were significantly affected by different planting methods and seeding rates. Concerning to the interaction between planting methods and seeding rates it was significantly affected number of kernels/spike -1 and grain yield (ardab/fed -1 ). Raised Beds method produced the maximum grain yield (21.98 ardab/fed -1 ) compared to the conventional methods; drilling method (16.41 ardab/fed -1 ) and broadcasting method (14.28 ardab/fed -1 ). Regarding to the seeding rates results found that 60 kg/fed -1 was the best seeding rate for conventional planting methods, while 45 kg/fed -1 seeding rate was the best for raised bed planting method.
