Abstract
Effect of FYM on tomato and cucumber was studied under green-house condition. There were two plots one of which was manured at the rate of 20 t per 10 a of FYM and the other was manured at the rate of 2 t per 10 a of FYM. There were four cropping seasons and in each plot the crops were grown in the pattern of cucumber-tomato-cucumber-tomato. The crops were produced during September 1975 to March 1977. The average conductivity value of the soils in these plots were 0.91 and 0.97 m mho; though these were higher than those of usual field, and were safe range for the growth of tomato and cucumber.
In cucumber, the standing crop-aging curves of the two plots did not differ appreciably at the beginning of the growth but differed considerably in the later growing stage. The CGR-aging curve of the first crop was multimodal but that of the third crop, which was grown one year after the first crop was unimodal. Specially, the curve of heavily manured plot approached more to unimodal than that of lightly manured plot.
In tomato, the curve had two peaks even in the fourth crop in heavily manured plot. The first peak was formed at about 40th day after having planted and the second peak at fruiting season. The difference of shapes of the curves in cucumber and tomato plants was due to the quantitative difference in the fruit production. The sugar content of cucumber of the third crop was higher than that of the cucumber of the first crop but there was no difference in the sugar contents of the fruits obtained from the two plots. In tomatoes, however, a different trend was observed.
