Abstract:

Nitrogen (N) and zinc (Zn) are two important essential plant nutrients, which have profound effect on growth, development, plant nutritional status and seed quality. The present study was conducted to observe the effects of N and Zn fertilization on N and Zn contents in seed and straw and seed quality parameters of BARI Gom-28. The study was carried out at the Regional Agricultural Research Station (RARS) in Jamalpur during December 2015 to April 2016. The experiment was replicated three times in a split plot design with four nitrogen levels (main plots) viz. (i) NF0 = control, (ii) NF1= 140, (iii) NF2= 160 and (iv) NF3= 180 kg ha-1 and five zinc levels (sub-plots) viz. (i) ZF0= Control, (ii) ZF1 = 2, (iii) ZF2 = 4, (iv) ZF3 = 6, and (v) ZF4 = 8 kg ha-1. The results revealed that N content of both grain and straw were the maximum (15.78% and 4.26%, respectively) in NF2while the highest contents of Zn were 306.58 and 122.58 ppm in ZF3. Interaction of N and Zn levels showed the highest N content of both grain and straw were 3.50% and 1.14%, respectively, with the combination of NF2ZF3. Similarly, the highest Zn content of grain and straw were 86.70 ppm and 32.76 ppm, respectively found in NF2ZF3. Seed quality study showed the highest germination percentage, vigor index, longest shoot, longest root, longest seedling and the highest dry weight of seedling in the interaction NF2ZF3. Thus, N and Zn fertilization @ 160 and 6 kg ha-1 produced correspondingly more N and Zn contents in the straw and seed and also improved seed quality of late sown wheat.
