The objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (DM yield) and 5 quality traits such as Dry Matter Digestibility (DMD%), Water Soluble Carbohydrates (WSC%), Crude Protein (CP%), Acid Detergent Fibre (ADF%) and total ash in tall wheatgrass (Agropyron elongatum). In th...
One way to increase crop yield per unit of area is to close the gap between actual and potential yield in cropping systems. This study was conducted to determine the factors that affeced wheat yield gap in Khorramshahr, Iran during 2018-2019 growing season. In this study 60 fields of different areas under cultivation, field management practices and grain yield yield levels were surveyed based o...
One of the main problems in crop production in Iran is the difference between actual yield and attainable yield which is called yield gap. Thus, identifying yield constraints and yield gap are important. Therefore, a study was conducted in 60 farms in Parsabad Moghan, during 2013-14 and 2014-15 crop years using Comparative Performance Analysis (CPA). In this study, several attributes related to...
The effects of tillage methods and residual management on yield and yield components of rapeseed (Brassica napus L. CV. Hyola308) were evaluated after rice harvest. The experiment was carried out during 2004-2005 cropping season in a factorical arrangement of treatments at Rice Research Institute of Iran (RRII) in Rasht, in a Complete Randomized Block Design with three replications. Treatments ...
The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...

This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...
