Effect of plant density and seed size on growth and yield of solanum potato in Khartoum State, Sudan.

Abstract

The effect of size of seed tuber (whole, 1/2 seed and farmer's seed piece) and intra-row spacing (15, 25, 35 cm) on growth and yield of potato was studied during three winter seasons in Khartoum State, Sudan at two locations, namely Shambat Research Farm and Shehainab Isand representing two soil types. Yield decreased with decrease in seed size and increase in spacing at both locations. Close spacing of 15 - 25 cm was better than wide spacing 35 cm. Seed size affected some yield parameters, i.e., marketable tubers plant-1, marketable tuber weight, number of marketable tubers per plant and number of stems plant-1. These parameters were also affected by plant spacing except number of stems.


Key Words: Potato yield, spacing, Sudan, tuber size
