Abstract

The field experiment was conducted at Student’s Research Farm, Khalsa College, Amritsar, Punjab, during Rabi season of 2022-23 to investigate the effect of intercropping and humic acid application on the productivity of potato. The experiment was laid out as a split plot design (SPD) with replicated three times viz. Four intercropping treatments (sole potato, potato + coriander, potato + lettuce, potato + methi) and six fertility treatments (HA0 (Control), HA1(Soil application of HA @7.5kg/ha), HA2(Foliar application of HA @7.5kg/ha in three splits at 25, 40 and 55 DAP), HA3 (Soil application of HA @15kg/ha), HA4 (Foliar application of HA @15kg/ha in three splits at 25, 40 and 55 DAP), HA5 (Soil application of HA @7.5kg/ha + Foliar application of HA @7.5kg/ha in three splits at 25, 40 and 55 DAP) were tried. All the intercropping treatment doesn’t show any significant effect on the growth parameter of the potato. The fertility treatments significantly affect growth parameters except days taken to plant emergence, emergence percentage and days taken to tuber initiation. The data revealed that the maximum growth parameters viz., plant height, stems/hill, leaf area index and total tuber yield were obtained in treatment HA3 (Soil application of HA @15kg/ha).

Conclusion

The study revealed that all three intercrops did not affect the growth parameters of potato negatively. The application of humic acid (soil application of HA @15kg/ha) to soil was more effective than foliar application as well as soil plus foliar application. Humic acid application to soil at the rate of 15 kg/ha improves the growth and yield of potato.
