Abstract:
Integration of soil amendment, tuber treatment and foliar spray have significant role in increase growth parameters and reduce the disease incidence of common scab. The maximum germination per cent was recorded in T2 treatments[Soil amendments with Gypsum @ 20q/ha + Tuber treatments with T. harzianum@ 5gm/kg of tuber+ Foliar spray of Copper Oxychloride with Streptocycline (3:1)], representing as 100% against 80% in case of control which was increase 25% germination over control. Similarly, the maximum plant height and number of leaves per plant were also recorded in T2 treatment, representing 6.16cm, 22.50cm, 37.33cm, 50.50cm, and 63.00cm plant height at 15, 30, 45, 60, and 75 days after sowing (DAS) respectively against 2.66, 11.00, 19.16, 28.16 and 37cm in case of control & 3, 10, 16, 22, 25 in number of leaves against 2, 6, 10, 14, 16 at 15, 30, 45, 60, and 75 days after sowing (DAS), respectively. IDM practices significantly reduced the disease incidence of common scab of potato as compared to control in field condition. The minimum disease incidence of common scab of potato with the value of 1.79% was recorded in T2treatment at the time of harvesting, followed by T6 [Soil treatment with Pseudomonas fluorescens(1% W.P, Cfu count: 2x 108Cfu/g) + Tuber treatments with T. harzianum@ 5gm/kg of tuber+ Foliar spray of Copper Oxychloride with Streptocycline (3:1)]and T1 [Soil treated with Bacillus subtilis (Baciforte, Cfu count: 1x 109cfu/ml) + Tuber treatments with T. harzianum@ 5gm/kg of tuber+ Foliar spray of Copper Oxychloride with Streptocycline (3:1)] treatmentsshowing with the value of 3.34% and 5.65% respectively, at the time of harvesting.
