Potassium Nutrition and Translocation in Cassava (Manihot esculenta Crantz) Intercropped with Soybean
Journal Title: Journal of Experimental Agriculture International - Year 2015, Vol 5, Issue 4
Abstract
Experiment to investigate the effect of potassium nutrition and translocation in cassava (Manihot esculenta Crantz) intercropped with soybean (Glycine max (L) Merril) was conducted at University of Nigeria, Nsukka in a derived savannah location of South Eastern Nigeria. The Effect of application of potassium fertilizer on two varieties of cassava intercropped with six cultivars of soybean was studied. Cassava tuber yield was significantly (P<0.05) affected by their varieties, fertilizer rate and cropping system. An increase in the supply of K+ by fertilization (N0K50 and N45K50) increased K+ accumulation in source leaves and caused increase in cassava tuber yield. The highest tuber yield of 42.0 t ha-1 was obtained with NR 8230 cassava variety intercropped with soybeans cultivars TGX 1894-3E with the application of N0K50, followed by NR 8230 intercropped with Samsoy-2 with N45K50 (40.5 t ha-1).
