Studying changes in plant canopy can help to improve architecture and increase yields. Specifically, for sorghum (Sorghum bicolor L.), characterizing identifying relevant traits be helpful not only its productivity but better fit this crop the rotation from a system perspective. With purpose, morphological characteristics of 20 hybrids were measured during 2022 growing season Wamego, KS, U.S. (...
The management of IT carve-out projects is very challenging due to the strict time frame, the severe contractual penalties, the huge number of stakeholders and the various as well as unique IT tasks that have to be conducted. Up to now, there is no instrument for evaluating the readiness of the IT for a carve-out and also not for managing such a project. In order to address this, we develop a m...
The study of body length and weight, maturity age, sex ratio, egg diameter, fecundity and spawning season of common carp has been done and the main aim was help to its population rebuilding. 1023 specimens were caught in Anzali wetland monthly from October 2015 until March 2017. There was used sexual maturity stages 3-7 for determining adults and, Gonado-somatic index and sexual maturity stages...
Extended Abstract Introduction and Objective: Due to the water resources limitation required for agriculture in Iran, providing effective methods to reduce the negative effects of drought on crop yield is one of the important studies to plant breeding. Drought tolerance in crops is very important. By using different cultivars of crops that are able to produce relatively good yield in drought s...
Seasonal and spatial variation in soil nematode communities was investigated in a field study conducted on a loessial plain in the northern Negev Desert, Israel. Soil samples from 0- to 50-cm depths were collected seasonally during 2001 under the canopy of Atriplex halimus and Hammada scoparia, and between shrubs (control). Total population abundance ranged from 8 to 887 individuals per 100 g s...
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. to do this, a study was conducted in 95 farms gorgan of in five villages, during two years 2007 and 2008. in this study, all of the information about management operations, soil and crop charac...
conclusions the produced compost in this study was mature and ready for use as an agricultural substrate or soil conditioner after 80 days of composting. results the results showed that the c/n ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the nh4+/no3 ratio decreased with increase in the t...
In order to determine the most important components of anise grain yield using regression analysis and path analysis, an experiment was conducted with 12 anise population in a randomized complete block design with three replications at research farm of the agricultural faculty, University of Zanjan in 2014 and 2015. The evaluated traits were days to flowering, days to maturity, grain filling p...
