“…The NUE decreased from 74.49% to 68.38% by increasing the rate from 120 to 180 kg N/ha. These results are similar to those reported by [32,33]. The 120 kg N/ha rate provides the best efficiencies.…”

The present study is highlighted through an experiment carried out over two consecutive years 2014-2016, in the sub humid region of Algiers. The methodology adopted concerns the variation of optimal nitrogen doses and their effects on the evolution of lettuce (Lactuca sativa L.) cultivation, whose socioeconomic impact is proven, using isotopic nitrogen (15 N) and the AquaCrop model. The experimental design adopted is of the complete randomized block type, with four (04) levels: 0 (control), 60, 120, and 180 kg N/ha with four (04) replicates. The results obtained showed that the 120 kg N/ha dose is the efficient dose to cover the nitrogen requirements of lettuce with an efficiency of 74.48%. The accuracy of the model in calibration was tested using the following statistical indicators: R2, nRMSE, and d, which are, respectively, 0.64 < R 2 < 0.81; 18 < nRMSE <46.3 and 0.78 < d < 0.94 for canopy coverage and 0.92 < R 2 < 0.98; 21.6 < nRMSE <34.5 and 0.91 < d < 0.96 for dry biomass. The AquaCrop model could be recommended as a practical tool to better manage agricultural practices including fertilization.

From these results, Jatropha seeds consider good or moderate source of benefit macro-elements N, P, and K [19].

Studies on irradiation of sewage sludge indicated its feasibility both economical and hygienically but work in this point is limited. Also the effect of non-irradiated and irradiated sewage sludge as a source of N on yield production and improvements fertility of sandy soil. In this research using the organic manure, the effects were increased soil fertility and crop yield. Aseeds yield production by Jatropha curcas L., these treatments can be arranged in the following descending order: T5> T6> T7> T4> T2> T3> T1. The best value of Ndff% recorded with rate 50% gamma irradiated sewage sludge + 50% ammonium sulphate fertilizer. Values of Ndfo % for 75.2%, 74.8% and 73.3% for (50% non-irradiated sewage sludge + 50% ammonium sulphate), (50% compost + 50% ammonium sulphate) and irradiated sewage sludge + 50% ammonium sulphate respectively. In general, the FUE% with 100% ammonium sulphate was ammonium sulphate alone lower than those recorded with ammonium sulphate plus none or irradiated sewage sludge and compost when T5, T7, T6 and T1 treatments were considered.
