Tetrakalai, the tetraploid form of Phaseolus aureus , was studied in the fields of the Indian Statistical Institute, Calcutta, in 1970, 1971 and 1972 to investigate its leaf protein yielding potentialities. In 1972 the yield of extracted leaf protein (LP) reached 458 kg/ha in 95 days, from harvests at 53 days along with the first regrowth cut. Of the two seed rates tried, 100 kg/ha, i.e. four times the conventional rate, gave a greater yield of protein than 50 kg/ha. Although not statistically significant, better protein yields were obtained with an increase in phosphate dose up to the 120 kg/ha level.
