Abstract
Low soil moisture and poor yields have been identified as key challenges in potato production. In 2023, a field experiment using a randomized complete block design was conducted to evaluate the effectiveness of various fertilizers enriched with biochar. The study included five treatments: Control (biochar only), NPK + Biochar, Farmyard Manure (FYM) + Biochar, Poultry Manure + Biochar, and Goat Manure + Biochar, with each treatment replicated four times. NPK was applied at 100:100:60 kg/ha, while poultry manure, goat manure, and FYM were applied at rates of 10 tons/ha, 6 tons/ha, and 20 tons/ha, respectively. Biochar and poultry manure resulted in superior growth performance, as indicated by increased plant height, canopy diameter, and the number of leaves and main stems per hill. Biochar combined with poultry or goat manure produced similar results for yield parameters (and fresh shoot weight, tuber diameter, weight, and number) and outperformed other treatments. The highest tuber yield was achieved with Poultry Manure + Biochar (52 tons/ha), followed by Goat Manure + Biochar (37.71 tons/ha). The lowest yield was observed under the control (25.71 tons/ha). The combination of biochar with poultry or goat manure proved to be more economically beneficial, demonstrating their potential to enhance potato yield and returns.
