This study was conducted under post-anthesis W and N deficiencies with the bread winter wheat ‘Chamran’ during the 2007-2008 and 2008-2009 growing seasons. The studied genotype ‘Chamran’ is tolerant to drought and heat and semi-tolerant to N- induced lodging with the average actual grain yield, individual grain weight, grain protein content and plant height of 6.2 t ha-1, 39 mg, 10.4% and 95 cm, respectively. This genotype is largely cultivated in south-west Iran and well adapted to the regions with hot and humid spring. The site is located in Ahwaz-Iran (latitude: 31°16′ N, longitude: 49°36′ E, altitude: 151 m). This region has a hot and humid climate; with 35-years mean annual maximum and minimum daily air temperatures of 32.7˚C in August and 19.5˚C in February, respectively. The precipitation during the first and second wheat growing seasons (November to May) was 329 and 352 mm, respectively. Long-term (1978-2010) meteorological data are shown in Table 1. Monthly average minimum and maximum temperature and the monthly precipitation in experimental site during the 2007-2008 and 2008-2009 growing seasons are given in Fig. 2. The soil was a montmorillonite clay loam, 0.5 m deep, low in total nitrogen (4-5 g kg-1), very low in organic matter (9-10 g kg-1) with a pH of 7.8 and Ec = 0.44 dS m-1. Table 2 shows some characteristics of the soil in experimental field.

Revised Text:

This study was conducted on post-anthesis W and N deficiencies in the bread winter wheat ‘Chamran’ during the 2007-2008 and 2008-2009 growing seasons.

The studied genotype, ‘Chamran’, is tolerant to drought and heat and is semi-tolerant to N- induced lodging, with an average actual grain yield. Individual grain weight, grain protein content and plant height are 6.2 t ha-1, 39 mg, 10.4% and 95 cm, respectively. This genotype is largely cultivated in south-west Iran and is well adapted to regions with a hot and humid spring.

The study site is located in Ahwaz, Iran (latitude: 31°16′ N, longitude: 49°36′ E, altitude: 151 m). This region has a hot and humid climate; with 35-year mean annual maximum and minimum daily air temperatures of 32.7˚C in August and 19.5˚C in February, respectively. The precipitation during the first and second wheat growing seasons (November to May) was 329 and 352 mm. Long-term (1978-2010) meteorological data is shown in Table 1. Monthly average minimum and maximum temperatures and the monthly precipitation at the experimental site during the 2007-2008 and 2008-2009 growing seasons are given in Fig. 2.

The soil is a montmorillonite clay loam, 0.5 m deep, low in total nitrogen (4-5 g kg-1), very low in organic matter (9-10 g kg-1), with a pH of 7.8 and Ec = 0.44 dS m-1. Table 2 shows some characteristics of the soil in the experimental field.
