4.1 Growth parameters .1 Plant height (cm)
Application of zinc, boron and manure significantly influenced the plant height of potato at different growth stages (Table 1 and Appendix 5). Results showed that the highest plant height (20.53, 60.36 and 66.40cm at 30 and 60 DAS and at harvest, respectively) was found from T7 (T1+ 3 t PM ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) which was statistically same with T6 (T1 + 4 t CD ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) at 60 DAS and at harvest followed by T5 (T1 + 5 kg Zn ha-1 + 2 kg B ha-1).
The lowest plant height (16.18, 54.27 and 60.48cm at 30 and 60 DAS and at harvest, respectively) was found from T1 (100 kg N ha-1 + 35 kg P ha-1 + 100 K kg ha-1 + 20 S kg ha-1) which was statistically similar with T4 (T1 + 5 kg Zn ha-1) at 60 DAS and at harvest. Similar result was also observed by Osman (2019) who found together application of B and Zn gave maximum plant height.

4.1.2 Number of stems hill-1
Significant variation was found on number of stems hill-1of potato at different growth stages due to application of zinc, boron and manure (Table 2 and Appendix 6). Results revealed that the highest number of stems hill-1(3.92, 4.68 and 4.92 at

30 and 60 DAS and at harvest, respectively) was found from T6 (T1 + 4 t CD ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) which was statistically same with T7 (T1+ 3 t PM ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) at all growth stages (at 30, 60 DAS and at harvest) followed by T5 (T1 + 5 kg Zn ha-1 + 2 kg B ha-1).The lowest number of stems hill-
1(2.94, 3.11 and 3.22 at 30 and 60 DAS and at harvest, respectively) was found from T1 (100 kg N ha-1 + 35 kg P ha-1 + 100 K kg ha-1 + 20 S kg ha-1) which was statistically similar with T4 (T1 + 5 kg Zn ha-1) at 60 DAS and at harvest. Singh and Singh (2018) found that Zn has significant effect on increased number of leaves in potato. Again, El-Dissoky and Abdel-Kadar (2013) observed leaves obtained with higher rate of boron. Similar result was also observed by Osman (2019).

4.1.3 Number of leaves hill-1
Number of leaves hill-1of potato was at different growth stages significantly affected due to application of and manure (Table 3 and Appendix 7). Results indicated that the highest number of leaves hill-1(13.24, 30.36 and 32.68 at 30 and 60 DAS and at harvest, respectively) was found from T6 (T1 + 4 t CD ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) which was statistically similar with T7 (T1+ 3 t PM ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) at the time of harvest but it was significantly same at 30 DAS and 60 DAS. The lowest number of leaves hill-1(9.44, 25.12 and 28.34 at 30 and 60 DAS and at harvest, respectively) was found from T1 (100 kg N ha-1 + 35 kg P ha-1 + 100 K kg ha-1 + 20 S kg ha-1) which was statistically same with T4 (T1

4.1.4 Fresh Weight of haulm hill-1 at harvest
Application of zinc and boron significantly influenced the fresh weight of haulm hill-1of potato (Table 4 and Appendix 8). Results showed that the highest fresh weight of haulm hill-1(244.70g) was found from T6 (T1 + 4 t CD ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) which was statistically same with T7 (T1+ 3 t PM ha-1 + 5 kg Zn ha-1 + 2 kg B ha-1) followed by T5 (T1 + 5 kg Zn ha-1 + 2 kg B ha-1) whereas the lowest fresh weight of haulm hill-1(186.50g) was found from T1 (100 kg N ha-1 + 35 kg P ha-1 + 100 K kg ha-1 + 20 S kg ha-1).
