Field experiments were conducted at the Punjab Agricultural University, Ludhiana in 1976 and 1977 to study the effect of foliar spray of TIBA at pre- and post-flowering stage, row direction and spacing with varying plant populations on the growth, yield and quality of soyabean (Glycine max. (L.) Merill) and mung bean (Vigna radiata (L.) Wilczek). The results showed the possibility of yield increase in soyabean with 40 and 80g (a. i.) per ha, although 40 g/ha proved better than 80 g/ha. Its spray at the pre-flowering stage proved better than that at the post-flowering stage. But in mung, it proved detrimental even at the lower concentration. Narrow row-spacing-higher sowing density proved better and row direction did not show any effect in both the crops.
