Abstract
A field experiment was conducted during 2019-20 at Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during kharif, rabi and summer season to judge the “effect of nutrient management on potato-based cropping system”. The experiment was laid out in randomized block design with three replications. The soil of experimental field was silt loam, having low organic carbon (0.31%), available N (140 kg/ha), available P (15.6 kg/ha) and available K (246.5 kg/ha). The rice variety NDR - 97, potato variety Kufri Khyati and bottle gourd variety Narendra Rashmi were planting/sowing in the respective seasons. Recommended dose of fertilizers (NPK) for rice (120:60:60), potato (150:100:120) and bottle gourd (60:40:40) were applied. For soil test basis application of N have to be increased by 30% for low fertility soil (available N). The result revealed that maximum yield like rice grain (3.8 t ha-1), potato tuber (35.42 t ha-1) and bottle gourd (30.40 t ha-1) were got under T8 treatment (N, P and K applied on soil test basis), while minimum in T1 plot (control plot). The highest net return and B:C ratio in rice (Rs 29519 and 1.21), potato (Rs 207040 and 2.68) and bottle gourd (Rs 135003 and 7.81) were recorded under T8 treatment (N, P and K nutrients applied on soil test basis). While minimum net return with T1 plot (control plot) in each season during investigation.
