Inorganic Fertilization

Abstract: The objective of this study was to evaluate the use efficiency of bio- and organic fertilizers comparing with mineral fertilizers on the performance of two lentil varieties, namely, Giza 51 and Sinai 1. Two field experiments were carried out at Gemmeiza (Gharbia governorate) and Mallawy (Minia governorate) Research Stations, Agricultural Research Center (ARC), Egypt; during 2012/2013 and 2013/2014 winter seasons. Five fertilization treatments were tested: (1) The recommended treatment (full dose of inorganic NPK). (2) Half dose of inorganic NPK (3) Half dose of NPK + organic fertilization (2.5 ton compost/fed). (4) Half dose of NPK + biofertilization as inoculation with Rhizobium and plant growth promoting rhizobacteria (PGPR). (5) Half dose of NPK + organic fertilization + biofertilization. The effects of these treatments on 14 lentil traits were studied. The traits included root nodulation status, plant growth, lentil yield and its components. In general, the best treatment at both locations was no.1, which produced the highest seed yield/fed of 5.41 and 4.66 ardab at Gemmeiza and Mallawy, respectively. However, the treatment no. 5 performed seed yield/fed close and insignificant with those of treatment 1 and recorded 5.09 and 4.66 ardab/fed in both locations, respectively. Similar trends were occurring for the most of other traits. The economic evaluation revealed that the highest net farm return was obtained from treatment fertilized with full dose of inorganic NPK fertilizers (5872 L.E), followed by the treatment received mixture of compost, biofertilizers and half dose of mineral NPK (5436 L.E). While the highest net return per invested one L.E. was achieved by mixture treatment (1.68 L.E.) followed by the recommended inorganic NPK treatment (1.84 L.E.). Using biofertilizer alone is economically better than using compost alone. Therefore, it could be possible to replace 50% of the recommended NPK mineral fertilization by a mixture of bio-and organic fertilization. These fertilization patterns may be considered the most effective strategy for reducing chemical fertilizer and supporting the sustainable agriculture system for producing legumes.
