Pakistan J. Agric. Res. Vol. 26 No. 1, 2013 GROWTH AND YIELD OF DIFFERENT BRASSICA GENOTYPES UNDER Arshad Ali, Imdad Ali Mahmood, Muhammad Salim, Muhammad Arshadullah* and Abdul Rasool Naseem** ABSTRACT:- A field study was conducted at farmer's salt-affected field (ECe=12.3 dS m ; pH=9.7; SAR=46.2) in Hafizabad to test growth and yield response of six Brassica cultivars (BARD-I, Dunkled, Rainbow, BRS-II, Sultan Raya and cv. 95102-5) under saline sodic conditions. Data on growth and yield parameters were collected randomly (average of five plants per replication) at the time of crop maturity. Ionic concentration in plant tissues and oil content in seeds were also determined. Comparatively more number of branches and pods per plant were produced by cultivar Dunkled closely followed by BARD-I while maximum seed yield (241.7 and 235.1 kg ha ) was obtained from Dunkled and Sultan Raya, respectively which was statistically at par. However, BRS-II and Rainbow showed significantly more percent oil contents in their seeds but genotype Dunkled showed minimum Na+ and K+ concentration in their tissues.
