Effects of Delaying Transplanting on Agronomic Traits and Grain Yield of Rice under Mechanical Transplantation Pattern
A delay in the mechanical transplantation (MT) of rice seedlings frequently occurs in Huanghuai wheat-rice rotation cropping districts of China, due to the late harvest of wheat, the poor weather conditions and the insufficiency of transplanters, missing the optimum transplanting time and causing seedlings to age. To identify how delaying transplanting rice affects the agronomic characteristics...
متن کاملcomparison of rice direct seeding methods (mechanical and manual) with transplanting method
the main method of rice planting in iran is transplanting. due to poor mechanization of rice production, this method is laborious and costly. the other method is direct seeding in wet lands which is performed in the one third of rice cultivation area of the world. the most important problem in this method is high labor requirement of weed control. in order to compare the different rice planting...
متن کاملComparison of Parachute, Line and Traditional Rice Transplanting Methods at Farmer’s Field in Rice Growing Area
Parachute transplanting method of rice as compared to line transplanting and farmer’s method of random transplanting was studied at 10 different locations viz., Kamonki, Wazirabad, Daska, Pasroor, Gujranwala, Sialkot, Lahore, Hafizabad and Sheikhupura during 2003 and 2004. Super Basmati was used as test variety. Yield and yield components of three transplanting techniques, averaged across 10 lo...
متن کاملEvaluation of the Agronomic Performance of Atrazine-Tolerant Transgenic japonica Rice Parental Lines for Utilization in Hybrid Seed Production
Currently, the purity of hybrid seed is a crucial limiting factor when developing hybrid japonica rice (Oryza sativa L.). To chemically control hybrid seed purity, we transferred an improved atrazine chlorohydrolase gene (atzA) from Pseudomonas ADP into hybrid japonica parental lines (two maintainers, one restorer), and Nipponbare, by using Agrobacterium-mediated transformation. We subsequently...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
