What methods are there to increase potato yields?
What methods can increase potato yields? Please give guidance. To increase potato yields, the following methods can be used: Removing the tail buds. Experimental observation has shown that after tail buds of potatoes grow into plants, the yield is only 1/3 of that of plants grown from top buds or side buds. For this reason, when cutting seed potatoes, the tail buds should be discarded. High-ridge cultivation. High-ridge cultivation...

To increase potato yields, the following methods can be used:
Removing tail buds. Experimental observation has shown that after tail buds of potatoes grow into plants, the yield is only 1/3 of that of plants grown from top buds or side buds. For this reason, when cutting seed potatoes, the tail buds should be discarded.
High-ridge cultivation. High-ridge cultivation with soil banking on both sides can increase the loose soil layer around the roots and stems, raise soil temperature, and meet the temperature needed for early root and stem development. Removing flower buds. The usable part of the potato is the underground tuber, and it does not need to flower and be pollinated to obtain it. To achieve high yields, buds must be pinched off as soon as they are seen, so as to save nutrients and promote tuber growth.
Less hoeing and more straight row cultivation. The fleshy roots of potatoes that can form tubers grow horizontally in the soil. Deep hoeing often cuts the fleshy extending roots, artificially causing reduced yields. Therefore, after the first hoeing, only cultivate between rows without hoeing again, which can effectively increase yields.
Supplementing magnesium to promote yield. Expert research has shown that during the growth of potatoes, especially during the tuber bulking stage, if magnesium fertilizer is sufficient, not only is the yield high, but starch accumulation is also greater and quality is better. Therefore, when the plants are 45 cm tall, apply 50-100 grams of magnesium sulfate per plant after dissolving it in water.
Foliar spraying. Under the condition of sufficient base fertilizer, starting from leaf expansion, spray the leaves once every 10 days with a mixture of 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, and 1000-fold triacontanol, spraying 3-5 times continuously, which can significantly increase yields.
