abstract water is a main factor in production of crops. optimizing the usage of water is essential especially in iran which is a dry and semi-dry country. investigation on the effect of different irrigation treatments on chilo suppressalis walker (lep.: crambidae), as the most destructive rice pest, can be an efficient strategy in optimizing usage of water in integrated crop management (icm). i...

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...

Abstract Background Rainfall is the key contributor to provide soil moisture for wet season rice (T. Aman) cultivation. Erratic rainfall often causes water shortage resulting negative impact on plant growth and grain yield. The study aimed determine suitable transplanting window that utilize maximum T. Aman rice. Firstly, three years field experiment were conducted in Kushtia, Bangladesh from A...

Quinoa ( Chenopodium quinoa Willd.) is a herbaceous C 3 crop that has demonstrated resilience in regions concurrently affected by climate change and food insecurity, such as sub-Saharan Africa (SSA). The photosynthetic rate productivity of crops are enhanced under increasing CO 2 concentrations. We looked at future trends SSA to estimate their impacts on yields Burkina Faso. Climate projections...

Abstract
 Fonio respond differently at different sowing conditions. Field experiment was conducted to assess the of fonio grain yield and its components when subjected seeding methods under rainfed condition during growing season 2021 2022. The Randomized complete block design with three replications adopted for experiment. result revealed that planting (dibbling, drilling broadcasting tra...

Rainfall is the main contributor to provide soil moisture for rainfed rice (Transplanted Aman) cultivation. The aim of study was investigate seed quality different transplanted Aman cultivars that are influenced by during ripening phases. For this, several experiments have been performed season 2014, 2015, and 2016 at Bangladesh Rice Research Institute, Gazipur. Two planting dates three varieti...
