The study has been made to understand the role of phosphorus in changing the boron (B) metabolism of mustard (Brassica campestris L.) cv. T9 by growing the plants in refined sand at deficient (0.3 mM), adequate (30 mM) and excess (300 mM) levels of boron, each at three levels of phosphorus (P), low (0.15 mM), normal (1.5 mM) and excess (3.0 mM). The synergy between B and P was reflected when low phosphorus accentuated the effects of B deficiency by lowering further the reduced dry weight, total seed yield and increased further the concentration of reducing sugars, phosphorylated protein and activities of acid phosphatase and ribonuclease in B deficient leaves. The effects of excess boron in mustard, viz., reduction in dry weight, seed weight, contents of reducing sugars, organic P, oil content, activity of ribonuclease and stimulating leaf boron, content of inorganic P, phosphorylated protein were accelerated further by combined toxicity of both nutrients. No seeds were produced at deficient B even on increasing the P supply to twice that of adequate amount. The synergy 315 was again observed between B and P when low phosphorus accentuated boron excess effects, i.e., the depression in dry weight, seed yield, reducing sugars, organic P, and oil content and increasing further B and activity of ATPase in young leaves in low P-excess B treatment in mustard.

“…Some researchers (Singh and Jones 1977) attributed this to soil processes, whereas others (Case et al 1964) attributed it to plant processes. Most probably, the phenomenon results from the balance between plant growth rate, root extension rate, soil P supply rate and fertilizer fixation rate (Grant et al 1972) . All of these processes are operative in the rapidly changing temperature regimes of spring and early summer.…”

Snerrenu, S. C. eNo Re,cz, G. J. 1985. Shoot and root response of wheat to band and broadcast phosphorus at varying soil temperatures. Can. J. Soil Sci. 65:79-88.Response of spring wheat (Triticum aestivum) to varied amounts of broadcast and band-applied phosphorus (P) was examined at soil temperatures of 10, 15, 20 and 25'C. The research emphasized the response of shoot yields with time and the root proliferation in the band-applied P. A non-destructive technique to measure growth with time was developed. This method allowed interpretation of plant responses even though the temperature treatments markedly changed the rate of physiological development. The relative plant-shoot response to P application did not change with time or developmental stage in this experiment. There was a marked effect of temperature on plant response to band-applied P. Band application was more efficient than broadcast P at 10'C soil temperature, but less efficient at 25'C soil temperature.Root proliferation in the fertilizer band was significantly different from the control soil-zone only at 10'C and was not diminished by concurrent application ofbroadcast P. The efficiency of band application was confirmed with ?P labelling of the banded P. Banded
