Fig. 3: Boundary line fitted for soybean yield versus the variety planted, and yield gap driven from soybean variety.
From: Yield gap decomposition: quantifying factors limiting soybean yield in Southern Africa
a, b represent boundary line and yield gap, respectively, in Malawi; similarly, c, d in Zambia; also, e, f in Mozambique. The names of the soybean varieties Malawi: 1—Tikolore, 2—Makwacha, 3—Nasoko, 4—Serenade; for Zambia: 1—Kafue (also called Tikolore in Malawi), 2—Dina, 3—Kamulanga (a local variety); for Mozambique: 1—Wamini, 2—Safari, 4—Serenade. The 1:1 represents when the actual yield is equal to the predicted yield. The points that fall below the 1:1 line indicate yield gap that cannot be explained by the soybean variety planted.
