Abstract

Two years experiments conducted to study the effect of foliar application of nitrogen and zinc and mulched methods on soil temperature, soil moisture, growth and yield of pepper (Capsicum annuum L.). The experiments were consisting of 4 foliar fertilizers as main plot F1 (without N or Zn) (control), F2 (RD of Nitrogen), F3 (RD of Zn) and F4 (RD of Nitrogen and Zinc) and 3 different mulches as sup plot (M1 without mulch, M2 with black plastic mulch (100 cm in width and 125 μ thick) and M3 with maize straw mulch) making 12 treatment combinations were laid out in a split plot design with 3 replications. The foliar application of both nitrogen and zinc gave the highest plant height, branches no per plant and fruit girth, while the application of Zn resulted on the highest fruit weight, fruit length and yield of pepper. Among mulch treatments the use of maize straw resulted on significantly superior to all other mulches followed by black plastic mulch, while the un-mulched treatments registered the lowest growth and yield parameters. Also the compensation between foliar application of N and Zn and maize straw mulch resulted on the highest plant height and yield, while the combination between application of Zn alone and use of maize straw gave the highest fruit no/ plant, fruit weight and fruit girth. The foliar application of fertilizer didn’t had any significant in regard to soil temperature and moisture. The use of black plastic mulch reported the highest soil temperature at (0, 5, 10 cm) and soil moisture content after (1, 2, 3 and 4 days from irrigation) followed by use of maize straw then un-mulched treatments. It seems that the combination foliar application of N and Zn and maize straw mulch gave the highest plant growth and yield of pepper. Also the use of maize straw as mulch gave moderate temperature and conserve the soil moisture.
