Abstract
Two field experiments were carried out at the Agricultural Production and Research Station, National Research Centre, Nubaria Province, Behaira Governorate, Egypt, during the two successive winter seasons 2010/2011and 2011/2012 to study the effect of foliar applied Zn at different growth stages (flowering and seed filling stages) combined with N levels (30 or 60 kg N/faddan, one faddan= 0.42ha) on yield, chemical constituents and nitrogen use efficiency of two chickpea cultivars (Giza-2 and Giza-88). The results show that chickpea cultivars significantly differed in plant height, weight of pods/ plant, seed and straw yields/faddan, nitrogen and protein contents in the seeds. Giza-88 cultivar significantly surpassed Giza-2 cultivar in plant height, number of pods/plant, weight of pods/plant, seed yield/plant, seed and straw yields/faddan. The combination of Zn foliar application at different growth stages and nitrogen fertilizer treatments resulted significant effects on plant height, number and weight of pod/plant, seed yield/plant and seed, straw and biological yields/faddan. Increasing N levels from 30 to 60 kg N /faddan without Zn application increased significantly yield and its components i.e. plant height, number and weight of pods /plant, seed yield /plant, N and protein contents in the seed. Application of nitrogen levels in combination with Zn as foliar application either at flowering or seed filling stages exhibited significant increases in most of the studied characters compared to without Zn application. The highest values of the most studied characters were recorded by treatment 60 kg N /faddan+ Zn foliar application at seed filling stage followed by the treatment of 60 kg N /faddan + Zn foliar application at flowering stage. It seems that Giza 88 was more responsive to the greater N dose and Zn ( 60kg N /faddan + Zn foliar spraying applied at the seed filling stage) than Giza -2 under the same conditions of this study. It could be concluded that chickpea plants favor the lower rates of applied N than the higher rates when grown under the newly reclaimed sandy soils and the cultivars were differed in their ability to utilize N efficiently. Also, late application of Zn especially at the seed filling period increased the ability of chickpea plants to use N effectively.
