| Abstract | ||||
| Two field trials were conducted on garlic clone Side-40 and Pea cv. Master-B as a companion crop. in the vegetable private farm at Kafr Hassan. near El-Mansoura. during 20022003 and 200312004 seasons to study the effect of some nitrogen fertilizer levets at 30. 60. 90 and 120 kg Nifed, biofertilizers (Control. nitrobien and rhizobacterin) and their interactions on the plant growth. yield and its quality of garlic and pea as well as chemical constituents of garlic and pea plants foliage and garlic bulbs. Generally. results showed that the growth and yield of garlic and pea plants were enhanced with increases N-levels. Most studied characteristics of garlic plants i.e.. plant height, shoot dry weight. bulbing ratio. yield. bulb weight and diameter as well as clove weight were significantly increased with increasing N-levels up to 120 kg N/fed. On the other hand. the growth, yield and yield components of pea plants was increased with increasing N-level from 30 up to 60 kg Ni‘fed. White. all studied characters of pea were not responded to high N-Ievels above 60 kg Nifed. Whereas. the increases of application-N significantly increased concentration of N. P. K. in garlic and in pea foliage. T83 and volatile oils in garlic cloves. On the other hand. biofertilizers had a significant effect on growth and yield of garlic and pea plants. In this respect. inoculation of garlic cloves or pea seeds by rhizobacterin pre-sowing significantly increased most studied characteristics of garlic and pea plants compared with the untreated ones. The combined treatments of N-levels and biofertilizers were generally more effective than with single ones. The best results were obtained by using 90 kg Nifed for garlic or 60 kg Nr‘fed for pea in the presence of rhizobacterin, Besides. these interactions resulted in the best net income from unit area. From the foregone it is evident that. inoculation garlic cloves or pea seeds by rhizobacterin as a biofenilizer ore-sowing rising their efficiency and reduce application rate of N-fertilizer about 25 %, thereby reducing costs and environmental pollution problems. Therefore. this treatment could be recommended for raising garlic and pea yields. improving their qualities and raising the mean of net income per unit area under similar conditions to this work. | ||||
