    Notes: Abstract The effect of boron (B) on peanut and soybean was examined in two omission and one B fertilizer rate trial on a Typic Tropaqualf in Northern Thailand. The B rate trial was combined with a comparison of the response of sunflower, green gram, black gram, wheat, and rice in addition to peanut and soybean grown in irrigated rice-based cropping sequences over two years. Omitting B induced the hollow heart symptom in 10% of peanut kernels with the incidence of hollow hearts closely related to B concentration in the kernels. Omission of B had no effect on the appearance of soybean seed or on the grain yield of either soybean or peanut. In the B rate experiment, omitting B depressed grain yield by 50% in sunflower and by 40% to 80% in black gram, induced B deficiency symptoms in green gram and the hollow heart symptom in peanut kernels, but had not significant effect on the grain yield of soybean, peanuts, rice, or wheat. B deficiency apparently depressed grain yield in black and green gram by delaying or inhibiting reproductive development thus reducing pod set.

    Boron deficiency in soybean [Glycine max (L.) Merr.] peanut (Arachis hypogaea L.) and black gram [Vigna mungo (L.) Hepper]: Symptoms in seeds and differences among soybean cultivars in susceptibility to boron deficiency (1993)

    Notes: Abstract The susceptibility of soybean cultivars (cvs) to boron (B) deficiency was examined in three experiments on a Typic Tropaqualf in Northern Thailand: one experiment also included peanut cv Tainan 9 and black gram cv Regur. Without added B (B0), B deficiency depressed seed yield by 60% in soybean cv NW1 compared with 30% in cv SJ5, 40% in cv 7016, 45% in peanut, and 93% in black gram. B deficiency also induced a localised depression on the internal surface of one or both cotyledons of some soybean seeds resembling the symptom of ‘hollow heart’ in peanut seeds. It induced 50% hollow heart in peanut, 17% in soybean cv NW1, 5% in SJ5, and 1% in 7016: black gram seeds had no symptoms. Addition of B decreased or eliminated the symptoms. In a comparison of 19 soybean cvs, the incidence of hollow heart symptoms in seeds at B0 varied widely from none in two cvs to 75% in cv Buchanan: cv NW1 showed intermediate susceptibility to B deficiency with 36% hollow heart in its seed while SJ5 was insensitive with 1%. Application of B eliminated hollow heart except from one seed in one cultivar. The results suggest that susceptibility to B deficiency is sufficiently important and variable among soybean genotypes to warrant its inclusion as a selection criterion when breeding cultivars for areas with low soil B.
