Response of new wheat varieties to some seedbed preparation methods and seeding rates.
Abstract: The production of food still the challenge for Egyptian planning, The experiments were carried out during 1999/2000 and 2000/2001 seasons at Gemmeiza Research Station, El-Garbia Governorate, The objective of the present study is to study the effect of some seedbed preparation systems and seeding rates on productivity of some new cultivars and obtain the technical package for each of them. Three seedbed preparation systems (T) were conducted as follows:
1. Chisal plow two passes.
2. Local combined unit for seedbed, preparation (chisal plow + rotary plow).
3. Chisal plow one pass followed by disc harrow.
Three seeding rates (S) (40,50, and 60 kg seeds / fed) and four wheat cultivars were used (Sakha 93, Gemmiza 7, Giza 168 and Gemmiza 9).
The results of the present investigation indicated that:
The use of local combined unit for seedbed preparation (chisel plow + rotary plow) had a significant effect on heading, maturity, plant height number and weight of grains/spike, 1000-grain weight, number of spikes/m2 and grain and straw yields. Increasing seeding rates from 40 up to 60 kg seeds/fed, came to heading and maturity early. Also, the tallest plants and highest number of spikes/m2 were produced by seeding rate of 60 kg/fed. While, number of grains/spike, grain weight/spike and 1000-grain weight were significantly decreased as the seeding rates increased up to 60 kg/fed. Gemmiza 7 wheat cultivar surpassed the others in plant height, number of grains/spike, grain weight/spike and 1000-grain weight. While as Gemmiza 9 was the leading cultivar and superior the other cultivars in number of spikes/m2 and grain and straw yields/fed. The interactions between cultivars x seed-bed preparation systems, cultivars x seeding rates and seedbed preparation systems x seeding rates were significantly affected on heading, maturity, plant height, 1000-grain weight number of grain/spike, number of spikes/m2 and grain and straw yields/fed. While, the interaction between cultivars x seedbed preparation x seeding rates had a signification effect on plant height in the second season. The results of indicated that the use of local combined unit and sowing with the rate of 60 kg seeds/fed of Gemmiza 9 wheat cultivar proved to be the most suitable treatments for the best wheat productivity.
