المستخلص Adding the recommended dose of nitrogen for kadotta fig trees (400 g N/tree/year)via 87.5% to 50% in inorganic form plus 12.5% to 50% in organic form enriched with EM1 atarate of 20 to 50ml / tree annually stimulated the three growth characters namely main shoot length, number of leaves/ shoot and leaf area than did N using completely via inorganic form or when inorganic N was applied at percentages lower than 50%. The best organic manure in this respect was chicken manure followed by compost then farmyard manure. The maximum values in this respect were recorded from trees received N as 50% inorganic + chicken manure at 50 % + EM1 at 40 ml/ tree/ year. Plant pigments namely chlorophyll a, b as well as total chlorophylls and percentages of N, P and K in the leaves were remarkably enhanced in response to the application of N at 37.5% in inorganic form + 62.5% in organic manures enriched with 20 to 50 ml/ EM1/ tree relative to using N completely via inorganic form. The promotion on plant pigments and nutrients was measurably associated with reducing percentages of inorganic N from 100 to 37.5%, and increasing the percentages of organic manures from 0.0 to 62.5% and levels of EM1 from 0 to 50 ml/ tree/ year. It is worth to mention that using chicken manure was superior than using compost and farmyard manure in this respect. Supplying Kadotta fig trees with N at 37.5 % in inorganic form + chicken manure at 62.5 + EM1 at 50 ml/ tree gave the maximum values. The highest yield in the first and second crop as well as total yield/ tree was obviously improved due to using the recommended doses of N through 50% inorganic N + 50 % organic manures + 40 ml EM1/ tree/annually. |
