Abstract
A research experiment was successfully conducted at farmers’ field in potato (Solanum tuberosum L.) during the year 2022 - 23 by application of lime to ameliorate the soil acidity for better production of potato in three villages of Lakhimpur District of Assam. There were 3 Technologies i.e. (TO-1: Lime @ 2 – 4 q/ha + 50% Recommended Dose of Fertilizer (RDF) that is NPK @ 60:50:50 kg/ha, TO-2: RDF (NPK@ 60:50:50 kg/ ha)and TO-3: Farmers Practice). The experiment was conducted in total area of 0.3 ha following randomized block design. The outcomes revealed that application of lime @ 2 – 4 q/ha in furrows + 50% RDF (NPK@ 60:50:50 kg/ha) gave higher yield of 93.7 q/ha and in farmers practice it gave 74.2 q/ha having B:C ratio of 2.33 and 2.10, respectively. With the integration of lime and chemical fertilizers the soil nutrient status improved as compared to the plot receiving only chemical fertilizers and to the Farmers practice. So, application of lime in furrows @ 2 – 4 q/ha and 50% RDF (NPK@ 60:50:50 kg/ha) is economical and profit oriented for small land holding farmers of that region and maintaining the soil acidity in Lakhimpur district of Assam.
