Abstract:
The IDM practices have ability to increase tuber germination and growth parameters, yield of potato and reduced severity of late blight of potato. The highest germination percentage was recorded from soil application of FYM + Poultry manure and Tuber treatment with T. harzianum during both the years. IDM approaches have ability to increases growth parameters and increase yield per plant in potato. The maximum plant height with 15.65, and 54.25 cm in 2016-17 and 15.75, and 55.00 cm in 2017-18 at 30, and 60 days’ age of seedling was found in T₉ treatment (Soil application of FYM + Poultry manure + Tuber treatment with T. harzianum + two foliar spray with Equation Pro). Similarly, total yield as 449.40 and 417.30 gm per plant was also obtained from T₉ (Soil application of FYM + Poultry manure + Tuber treatment with T. harzianum+ three foliar spray with Equation Pro) treated plant as against 218.78 gm and 211.68 gm in case of control in year 2016-17 and 2017-18 respectively. As per concerned of disease severity of late blight, the minimum with 9.05% and 14.92% during 2016-17 and 9.65 and 15.10% during 2017-18 were recorded in T9 (Soil application of FYM + Poultry Manure + Tuber treatment with T. harzianum + three foliar spray with Equation Pro) treated plant as against 61.35 and 82.55 and 62.00 & 82.95% at 75 and 90 days after sowing respectively in case of control.
