in order to evaluate the effects of drought stress and planting method on yield and yield components of two chickpea cultivars (cicer arietinum l.), an experiment was carried out at the research field of faculty of agriculture; shiraz university, using a split factorial randomized complete block design with four replications. the main factor was irrigation stop at different growth stages of chi...

due to limitation of conventional water resources, the use of unconventional water for agriculture is unavoidable. therefore, in order to investigate the effect of using different amounts of municipal wastewater on yield, yield components and water use efficiency of cotton in drip irrigation systems, a field experiment was carried out during 2010 and 2011 growing season at experimental farm of ...

to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

Agricultural crops experience diverse mechanical stimuli, which may affect their growth and development. This study was conducted to investigate the effects of mechanical stresses caused by hanging labels from the flower petioles (HLFP) on plant shape and cotton yields in four cotton varieties: CCRI 41, DP 99B, CCRC 21, and BAI 1. HLFP significantly reduced plant height by between 7.8% and 36.5...

Crop nitrogen is an efficient index for estimating crop yield. Using hyperspectral information to monitor in cotton real time can help guide cultivation. In this study, we used drip-irrigation Xinjiang as the research object and employed various treatments explore correlation between vegetation indexes leaf concentration (LNC) canopy density (CND) of different growth periods interannual. We 30 ...

This study was conducted for investigating the impact of irrigation interval and deficit on seed cotton yield, fiber quality, water productivity (Gossypium hirsutum L.) in Şanlıurfa province Türkiye during years 2020 2021. The experiment using a randomized complete block design with split plots. main plots included three intervals (D1: 4 day, D2: 8 D3: 12 day), while sub-plots consisted levels ...

Frequency of irrigation to the crops is the key factor for proper growth and economic yield. Therefore, in the current study growth of broccoli plants was investigated under different irrigation levels in pot culture condition. Five levels of irrigation schedules were applied including I0 [Non-irrigation control], I1 [Irrigation up to 15 days after transplanting (DAT)], I2 [Irrigation up to 30 ...

the objective of this study was to evaluate the effect of different levels of irrigation and nitrogen fertilizer on nitrate movement, yield, and water use efficiency (wp) of corn in no-till planting method. the research was conducted in two years as a randomized complete block design arranged in a split block treatment design with three replicates in the safiabad agricultural research center. i...
