The Effect of KNO₃ on the Growth of Sorghum Plant (Shorgum bicolor var. numbu)

The purpose of this research is to know the effect of giving KNO3 on sorghum plant’s growth (Shorghum bicolor var. numbu). This study was conducted a Complete Randomized Design by using four treatments (K1, K2, K3 and K4), each treatments did in five repetitions. K0 (without KNO3= only aquades), K1 were given 15% KNO3, K2 were given by 30% KNO3, K3 were given 45% KNO3 and K4 were given 60% KNO3. Parameters measured were the number of leaves, the weight of wet leaves, the weight of dry leaves, malai’s weight, and chlorophyll contents (a cholophyll, b chlorophyll, and total chlorophyll). Data analyzed by using ANOVA (Analysis of Variance) then continued by calculating honestly significant difference (Tukey –HSD Test) at 0,05 significanct level. The results show that there was a non-significant difference for all parameters of giving KNO3. However, K4 treatment (60%) had significant difference for all parameters like; leaf-number, the weight of wet leaves, the weight of dry leaves, heavy malai. In spite of this, the chloropyll content on Sorghum plant did not show any significant results. This study still not shows the best result and maximum effects KNO3 on Sorghum plant’s growth. Hence, deeper assessment is much needed
