1. The responses of plant growth at early stage and yield to phosphorus were relatively great in this experiment. The F value for main effects of P with all yield measurements was significant at 596 level. While, Nand K had little effect on growth and yield measurements. There were not any interaction effects between N, P and K. The response of flesh thickness to P was slight great, while P had little effect on firmness of pepper fruits. Both response of ascorbic acid content in pepper fruits to supply of K and response of keeping quality of green pepper fruits to supply of N were also relatively great. There was not a high correlation between the weight of red mature hybrid fruit produced by hand pollination and number of normal seeds per fruit. The coefficient of correlation was +0.397. Percentage of normal seeds was depressed by low N. Seeds from low K treatment declined in germination faster than did seeds from the complete treatment. In general, average number of hybrid seeds per fruit between NPK treatments was 40% lower than that of natural pollinated seeds. 2.The supplies of Mg, B, Mo minor elements seemed to have some slight effects on growth, yield and quality measurements. Mg and Mo deficiency resulted in smaller plant growth. B deficiency resulted in low yields. B deficiency also resulted in flesh thickness significantly different at the 596 level, but did not significantly affect on firmness and shelf life of green pepper fruits. Also, the supply of minor elements seemed to have little effect on seed production including average number of seeds per fruit, average weight of seeds per fruit, weight of 1000normal seeds, percentage of germination and rate of germination. 3. The differential supply of water was shown to have effects on plant's growth and yield measurements. The water requirement for one crop of peppers seemed to need more than 320mm. The correlation between water supply and flesh thickness was very poor, as the coefficient of correlation was -0.020!J. Water supply also had little effects on shelf life of green mature fruits and percentage of normal seeds from red mature fruits.
