Effect of nitrogen and potassium on tuber yield and quality of yam bean (Pachyrrhizus erosus)
Experiment involving three levels of nitrogen and potassium (40, 80 and 120 kg/ha) along with an absolute control (NOKO) was conducted to study the influence of nitrogen and potassium on the performance of two yam bean entries (R.M.-1 and L-109) during two successive years (1986-87 and 1987-88). Uniform basal dose of 60 kg P2O5/ha was applied except control plots. There was no significant yield variation between the two entries, however, R.M.-1 produced significantly higher tuber yield in the second year. The tuber yield was found maximum under N120K60 which was on par with N120K40 and N120K120. But N120K80 produced longer tubers. Highest net income (Rs. 14,188.10) per hectare was obtained by the application of 120 kg N and 80 kg K2O over no application of fertilizer. TSS content was found maximum in the tubers of control plots.
