Onion (Allium cepa L.) is an important commercial vegetable crop grown by small-holder farmers in Kenya for both local and export markets. The national average production is low and quality is highly compromised due to use of low yielding varieties and poor agronomic practices. Field experiments on the influence of nitrogen and time of application on growth, yield, and quality of onion bulbs were conducted in 2014 and 2015 at the National Agricultural Research Laboratories. The experiments were laid out in a Randomized Complete Block Design (RCBD) with a split-split arrangement and replicated three times. Nitrogen (N) was applied as Calcium Ammonium Nitrate at five levels including, 0 (control), 26, 52, 78 and 104 kg N ha-1. These were applied at four different times of applications at three, six, nine and twelve weeks after transplanting. Two onion varieties popularly grown in Kenya were used, the Red Creole and Red Tropicana F1 hybrid. Nitrogen and time of application showed signi...

The   apple (Malus domestica Borkh.) is believed to   have   originated   in   the   Caucasus   mountains   of south-western Asia.   The cultivated apples belong to the species Malus pumila or Malus sylvestris. Apple is undoubtedly the most important temperate fruit. It is the most important temperate fruit in the world and India stands 5th in the production of apple. In India, apple cultivation is extremely profitable and has become   the   major   industry   of   Jammu and   Kashmir and Himachal   Pradesh. The present commercial cultivars of apple are far improved from the wild apples from which they developed over many centuries. And to commercialize improved varieties of apple in India, the varieties need to be evaluated for their growth characteristics. Keeping this view, the study was taken to evaluate four new exotic   varieties   of   apple   viz., Super Chief   Sandidge, ...
