Abstract

In order to further improve yield and quality of tomato by proper fertilization on Chengdu Plain,a field trial was conducted to examine effect of calcium(Ca),magnesium(Mg),manganese(Mn) and zinc(Zn) fertilizers on tomatoes.Results showed that application of Ca,Mg,and Zn on the basis of nitrogen(N),phosphorus(P) and potassium(K) increased tomato yield by more than 10%,reduced nitrate content in fruit to 80% compared to NPK treatment.It also increased vitamin C by 42.6% and improved the sugar/acid and solid material/acid ratios,and finally resulted in a net income increase by more than 10%.Application of Mn reduced tomato yield.It is recommended that Ca,Mg and Zn are crucial to tomato production on Chengdu Plain and the best effect can be achieved when they are used together.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
