Some studies on the influence of spacing, seed piece and manuring on the yield of potato crop

Conclusions

• 1. Yield increases with more manure, larger size of seed piece and closer spacing between hills. Maximum increase is noticed under manuring factor.

• 2. Size of seed piece affects the yield but the degree of effectiveness varies with the level of manuring. At high manuring size of seed piece proves less effective and the difference in yield from 5, 10 and 20 gm. seed piece is relatively small.

• 3. As regards planting distance, a spacing of 8 inches is more suitable at low and medium manuring and with high manuring, close planting gives more yield.

• 4. Size of potato improves by heavy application of manure, using small seed pieces in comparison to large sets and adopting wider spacing between hills.

• 5. It is concluded that potato growing is not profitable under conditions of poor manuring. When manuring is moderate, the use of 10 gm. set sown 8 inches apart is more desirable and with heavy manuring 5 gm. seed piece sown 4 inches apart proves more useful.
