چکیده
Zero tillage straw retained with optimum K is an important strategy to increase cotton ( Gossypium hirsutum L.) yield and efficiency in wheat Triticum aestivum L.)-cotton system. A 2 years field experiment was conducted during 2018, 2019 study the impact of [zero as such on soil surface (ZT SAS ) zero burnt SB )] five rates were 0, 20, 40, 60 80 kg ha -1 use efficiency. Results indicated that bolls/plant –1 , weight per boll, seed yields, ginning out turn agronomic highest 60-80 . Interactions revealed ZT had higher bolls/plant, bolls weight, yields compared indices decreased increasing rate. 20 gave greater than other combinations. potassium hectare may be a sustainable environmentally safe enhance fertility Keywords: tillage, residue management, potassium, yield, DOI: 10.7176/CPER/64-03 Publication date: January 31 st 2022

Effect of cropping system on cotton biomass accumulation and yield formation in double–cropped wheat–cotton
Wheat–cotton double cropping practices on a large scale in cotton belt of the Yellow RiverValley and the Yangtze River Valley in China. Field experiments were conducted to determinethe effects of wheat–cotton double cropping on cotton biomass accumulation and yieldformation during 2011/12 and 2012/13 growing seasons. Two cotton cultivars, Siza 3 (mid–latematurity) and CCRI 50 (early maturity), ...
متن کاملTillage effects on energy use and greenhouse gas emission in wheat-cotton rotation
Crop production process utilizes input energy and produces some biomass energy as output. During this process, greenhouse gases (GHGs) are also emitted which can make environmental risks. In this study, input and output energies, energy indices, and GHG emissions arising from inputs were estimated for wheat-cotton rotation under different tillage practices in Fars province. The study was condu...

Of the several mechanisms that can bring about efficient resource use, the most widelyapplicable one is intercropping systems that can make better use of resources. The aim of thisstudy was to evaluate resource capture and resource use efficiency in transgenic cotton-peanutintercropping system and in their respective sole crops with using 25-50% substitution ofrecommended dose of nitrogen (RDN)...
متن کاملProductivity and economic efficiency of wheat in rotation with cotton
ABSTRACT- Crop rotation has many benefits for agro-ecosystems production. In order to evaluate two current rotation systems of wheat (Triticum aestivum L.) production in Kamalabad region of Fasa, an experiment was conducted during 2015-2016 growing season. The rotation systems were fallow-wheat and cotton (Gossypium spp.)-wheat. Research plots were arranged as a randomized complete block design...
متن کاملIntegrative impacts of soil tillage on crop yield, N use efficiency and greenhouse gas emission in wheat-corn cropping system
Wheat-corn cropping system is one of the most important grain production systems in theworld. However, the integrative impacts of soil tillage on crop yield, N use efficiency (NUE)and greenhouse gases (GHGS) emissions are not well documented in this system. Thus, a twoyear field experiment was carried out in a typical wheat-corn cropping system with four tillageregimes during the wheat season, ...
