| Abstract | ||||
| The effects of organic, mineral, and bio-N- fertilizers on growth and productivity of pepper plants (Capsicum annum) CV. (Dolman- 10191) grown in a modified green house under fertigation system were studied in two intervals experiments of 2013 and 2014. The results indicated that, applying organic fertilizer (as biogas digester residue or farm yard manure at rate 20m3/fed) combined. with bio-N fertilizer (microbin at rate 4L/fed) and mineral – N fertilizers at rate of (19-19-19)N-P-K commercial liquid fertilizer gave the vigorous plants expressed as plant length, number of leaves and stems as well as shoots dry weight in both seasons. Moreover, it increased number of fruits and total fruit yield per plant as well as the best physical properties of fruits i.e., diameter and flesh thickness. In addition, it gave the best values of total acidity, vitamin C content, TSS percentage, dry matter and N, P, K, Fe, Mn, Zn, Cu, Ni and Pb contents of fruits. It could be noticed that organic, mineral, or bio N fertilizer applied alone has a little effect when compared with mixed application of two of them or combines application of all of them. | ||||
