Removing the terminal bud in comparison with spraying of benzyl adinine and their effects on growth and roductivity of Eggplant under different rates of nitrogen fertilization [electronic resource].

Includes reference.

Two field experiments were carried out during consecutive summer seasons of 2007 and 2008 at the Experimental Farm, Faculty of Environmental Agricultural Sciences, EI-Arish, Suez Canal University, Egypt to study the effect of four nitrogen rates (0, 60, 90 and 120 kg/fed.), foliar spray with benzyl adenine (BA) at 25 ppm and removing the terminal bud (RTB) on growth, Yield and nitrogen use efficiency of eggplant under North Sinai conditions, and the results indicated that: It has been found that fertilization of eggplant with 90 kg N / fed.recorded the tallest plants and increased dry weight of roots, branches, and total dry weight / plant. It also, increased average fruit weight, yield /plant, fruit length without significant differences with application of 60 or 120 kg N/ fed. as well as increased the nitrogen use efficiency, whereas N at 120 kg / fed. Recorded the maximum values of N content in leaves and stems, yield/plant, total yield/ Fed. And the relative total yield (%). Number of branches/plant and the relative branching (%) were significantly decreased with increasing nitrogen rates in the first season, whereas control treatment recorded the highest value of number of branches/ plant.
