in order to evaluate physiological and morphological characteristics and yield of soybean (glycine max l.) cultivars under different planting ratios a field experiment was conducted based on randomized complete block design with four replications at the gaem shahr agricultural research centre of mazandran province, iran, during 2008. two soybean cultivars (032 and sari) were planted in row inte...
to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had signi...
To investigate the effect of different planting row ratios of parental lines and agronomic methods on synchronizing of flowering and seed production of SCK703 hybrid maize, a field experiment was carried out as a strip plot arranegemnts in randomized complete block design with three replications in southern Kerman agricukltural and natural rseraech and education center, Jiroft, Iran, in 2015 gr...
Plant-plant interactions that change along environmental gradients can be affected by different combinations of environmental characteristics, such as the species and planting density ratios. Suaeda salsa and Scirpus planiculumis are regionally dominant species in the Shuangtai estuarine wetland. Compared with non-clonal S. salsa, clonal S. planiculumis has competitive advantages because of its...
In order to investigate the effect of bio-fertilizers on the effective physiological characteristics and to improve the performance of common bean (Phaseolus vulgaris L.) and black cumin (Nigella sativa L.) in different ratios of intercropping, a field experiment was conducted as a factorial based on a randomized complete block design with three replications; this study was carried out at the r...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
the effects of planting date and single irrigation (si) allocation scenarios on increasing and stability of yield were investigated to determine the total water productivity and economical water productivity (wpe), for rainfed wheat at dryland agricultural research institute in maragheh, iran, during 2000-2004. the treatments included three sowing dates (early, normal and late), four allocation...
to investigate the effects of intercropping of basil (ocimum basiilicum l.) and cowpea (vigna unguiculata l.), different levels of nitrogen fertilizers on basil and cowpea yield, an experiment was carried out during 2010 and 2011. experimental factor were included weed treatment (weeding and unweeding), three levels of nitrogen fertilizer (0, 50 and 100 kg ha-1), different planting ratio, (p1: ...
In order to evaluate the suitability of maize hybrids in different planting dates, an experiment was conducted as split plot in JalilAbad, Varamin, Iran in 2015. Main and sub plots were planting date (D1: April 4, D2: April 19, D3: May 5, D4: May 20) and maize hybrids (H1: Gazda, H2: Maxima, H3: KSC 701, H4: AS160) respectively. Results indicated that there was variation between hybrids in term...
Optimum planting geometries have been shown to increase crop yields in maize-soybean intercrop systems. However, little is known about whether changes in planting geometry improve the seasonal water use of maize and soybean intercrops. We conducted two different field experiments in 2013 and 2014 to investigate the effects of changes in planting geometry on water use efficiency (WUE) and evapot...
