  • The effect of nitrogen (N), phosphorus (P), and calcium (Ca) fertilizations on the seed yield and quality of F ^hybrid tomato seed grown by NFT were investigated. Higher N application (8 me/I) at the onset of flowering increased seed yield. Increasing N level at later growth stage increased seed yield of upper cluster, therefore total seed per plant also high. Four me/I ofCa level combined with 8 me/I ofP level increased in the weight of fruit and seed. However, at the case of 8 me/I ofCa, increasing P level declined fruit and seed yield severely. Especially when both P and Ca level were high (8 me/I), fruit and seed yield markedly decreased into about 60 %. Effect ofN content in the seed will reflect to the N compounds constituent there and consequently may influence seed germination.
