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.

Is Your Bunny Sick? Rabbits are at the bottom of the food chain and in the wild the weakest are the first to be preyed upon. Thus, rabbits instinctively hide illnesses and injuries to avoid detection by animals of prey. This may be a good survival tactic in the wild, but for domestic rabbits, hiding their symptoms of illness only misleads their caretakers and prevents prompt medical atten
Sectoral networks To improve for students the step from school to the labor market, we have chosen to set up a network of cooperation with certain industries. The sectoral networks bring actors from the educational field and the labor market together, to improve the transition from education to employment in certain industries. Based on a solid analysis we set up incentive
