Effect Of Liming On The Growth And Yield Of Four Varieties Of Soybean (Glycine Max (L.) Merrill) In The Forest Zone Of South Eastern Nigeria.
ABSTRACT
Field experiments were conducted during the 2003 and 2004 cropping
seasons at the Eastern Farm of Michael Okpara University of Agriculture,
Umudike, to assess the effect of liming on four varieties of soybean (early
maturing TGX 1485 — ID, TGX 1799 — SF, TGX 1805 — 8F and medium
maturing TGX 1440 — 1I). In each year, the experiment was laid out as a
split — plot in a andomised complete block design with three replicates.
Five lime rates of 0, 0.5, 1.0, 1.5 and 2.0 t/ha were applied to the main-
plots and the four soy.tean varieties were planted in the sub-plots. Liming
significantly increased soil pH, number of nodules per plant, number of
pods per plant and grain yield of soybean, especially in 2004 cropping
season, but had no effects on plant height, nodule weight, shoot dry
matter, days to 50% flowering and 100-seed weight. The 1.0 I/ha lime
rate proved the best and is recommended for high grain yield in soybean.
The medium maturing TGX 1440 — lB variety gave on average,
significantly higher number of leaves per plant, number of pods per plant
and grain yield than other varieties. There were generally no significant
effects of lime and variety interactions on soybean growth and yield.
