Prevention of nitrogen deficiency in maize. - PlantwisePlus
Webb13 apr. 2016 · Nitrogen is one of the limiting nutrients in maize production. Its deficiency results in reduced yields and this is a common problem in many parts of Malawi. … Maize grain yield ranged from 101.00 to 7450 kg ha−1 across the nutrient treatments (Tables 2 and 3). Except under NPKB plots, average grain yield of the NPK and NPK + treatment plots were above 3,000 kg ha−1. The NPKZn treatment increased grain yield by 28% compared to NPK.
