Evaluation of different potato based cropping sequences under rainfed mid-hill conditions of Uttarakhand

In order to assess the yield performance and profitability of eight potato based crop sequences viz., potato-vegetable pea, potato-french bean, potato-palak, potato-vegetable rai, potato-radish, potato-cauliflower, potatocabbage and potato-amaranthus, an investigation was under taken during spring-summer (potato), rainy (french bean, palak, radish, cauliflower, cabbage) and rainy-autumn (vegetable pea, vegetable rai and amaranthus) seasons of 2010–11. Crop sequence potato-cabbage, proved the best with respect to Potato Equivalent Yield (PEY) (473.91 q ha⁻¹) and net profit (Rs. 68,441.66 qha⁻¹). This sequence had recorded an additional net income of Rs. 62,587.50 ha⁻¹ over conventional sequence, potato-amaranthus. In terms of production efficiency (PE), potato-french had given the highest yield per hectare per day(2.51 q).
