This investigation was carried out during the two summer seasons of 2015 and2016 in sandy soil on potato culitvar "Sante" to study the effect of using 100%compost (15 t/fed.) and 50% compost + nitrogen fixing bacteria (Azotobacter, andPseudomonas alone or together) on potato yield and quality as compared to theconventional mineral fertilization (120-75-150 kg/fed. NPK + 5 toncompost/fed.(control)). No significant differences in tubers yield/fed. were detectedbetween mineral fertilization (control) and using 100% compost (15t/fed).However, control treatment significantly produced a high yield per feddan,more than using 50% compost + any biofertilizer treatment.Using composttreatment at 15 t/fed.execeed all biofertilizer treatments in marketable yield in bothseasons, but without significant differences as compared with mineral fertilization(control).No significant differences in tuber dray matter and content of starch intuber were found between using compost treatment at 15 ton/fed. and mineralfertilization treatment (control)in both seasons. Nevertheless, application of 50%compost+ 4 applications of Azotobacter and Pseudomonas had the highest tuberconcentrations of starch and nitrogen with significant differences as compared withthe mineral fertilization.Using50% compost + 4 applications of Azotobacter orPseudomonas or both (Azotobacter + Pseudomonas )and application of 100%compost caused producing potato tubers with the lowest concentration of nitratewith significant differences as compared with the mineral fertilization. Nosignificant differences were detected between mineral and organic fertilizersconcerning P and K concentrations in tubers.

Aims: Two field experiments have been carried out to study the effect of different irrigation periods in the presence of compost as an organic amendment on the yield and quality of lupine (Lupinus termis L.) under the sandy soil conditions. Study Design: Split-plot design.  Place and Duration of Study: The successive winter seasons of 2016/2017 and 2017/2018 at the Ismailia Agricultural Research Station, (30°35'30" N 32°14'50" E elevation 3 m), Agricultural Research Center (ARC), Egypt. Methodology: Compost has been applied at the rates of 11.90, 23.81 and 35.71 ton/ha before planting. Three irrigation intervals were assigned after planting by 3, 6, and 9 days; the applied water volume for each was 4761.91 m3/ha. Results: After harvesting, some parameters were estimated. As the compost rates increased, the soil EC significantly decreased while the available N, P, K, and Fe were significantly increased by 9.51, 12.79, 5.17, and 5.8%, respectively. For same compost rate, the irrigation intervals (3, 6, and 9 days) significantly decreased the available N relatively by 2.88, 5.16, and 6.96%, respectively and the available K by 3.45, 5.06, and 4.37%, respectively. The 6 days interval showed that most significant increase in the seeds' content of nutrients at different compost rates and the seed yield has increased by 19.59, 22.31, and 21.88% for the compost rates of 11.90, 23.81, and 35.71 ton/ha, respectively. The relative increase was by 20.48, 7.63, 4.49, 10.89, and 14.92% for the crude protein, crude lipids, total ash, TSS and the amino acids, respectively. The effect of treatments on the relative shoot moisture (%) and the field water use efficiency (F.W.U.E.) (kg/m3) was discussed. Conclusion: The 6 days irrigation interval along with a compost application rate of 23.81 ton/ha can be recommended for lupine grown in sandy soil as they showed the most significant increase in the nutrients content of seeds by 22.31%.
