in order to study the correlation between morphophenological and quantitative traits with yield and to determine the most important traits for yield, 600 ecotypes of mung bean were evaluated in normal and limited irrigation conditions through augmented design. computation of correlation coefficients showed that in two conditions, number of pods per plant, harvest index and biological yield had ...

The aim of this study was to determine nature and extent of variability parameters and their utilization in barley breeding programme. A total of 45 F1s along with their parents and F2 populations were evaluated in a randomized block design with 3 replications during Rabi (winter season) 2014. The various traits measured were days to 50% flowering, days to maturity, plant height, flag leaf area...

The response of growth and yield of rainfed-chickpea to population density should be evaluated based on long-term experiments to include the climate variability. This is achievable just by simulation. In this simulation study, this evaluation was done by running the CYRUS model for long-term daily weather data of five locations in Iran. The tested population densities were 7 to 59 (with interva...

The present study was conducted to evaluate the effects of plant density on yield and yield components of different safflower cultivars. For this purpose, a factorial experiment based on randomized complete block design was conducted with four replication and two factors included cultivar (Esfahan, Goldasht and Sofeh) and plant density (40, 65 and 90 plants/m2). Results showed the main effect o...

The experimental material consisted seven mutagenic populations of chickpea in M3 and M4 generation, control (Avarodhi) and check variety Pusa 312. The experiment was conducted during rabi 2009-10 and 2010-11. On the basis of per se performance, six mutagenic populations were selected for high seed yield coupled with high harvest index and more number of pods per plant. None of the mutagenic po...

A major challenge in rice (Oryza sativa L.) production is to enhance water use efficiency (WUE) and maintain or even increase grain yield. WUE, if defined as the biomass accumulation over water consumed, may be fairly constant for a given species in given climate. WUE can be enhanced by less irrigation. However, such enhancement is largely a trade-off against lower biomass production. If WUE is...

Determination of the optimum harvest window plays a key role in the agro-food chain as the quality of fruit depends on the right harvesting time and appropriate storage conditions during the postharvest period. Usually, indices based on destructive measurements are used for this purpose, like the De Jager Index (PFW-1), FARS index and the most popular Streif Index. In this study, we proposed a ...
