Few studies in Brazil have addressed the need for micronutrients of physic nut focusing on physiological responses, especially in terms of photosynthesis. The objective of this study was to evaluate the effects of omission of boron (B), copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) on Jatropha curcas L.. The experimental design was a randomized block with four replications. The treatments were complete solution (control) and solution without B, Cu, Fe, Mn, and Zn. We evaluated the chlorophyll content (SPAD units), photosynthetic rate, dry matter production and accumulation of micronutrients in plants, resulting from different treatments. The first signs of deficiency were observed for Fe and B, followed by Mn and Zn, while no symptoms were observed for Cu deficiency. The micronutrient omission reduced the dry matter yield, chlorophyll content and photosynthetic rate of the plants differently for each omitted nutrient. It was, however, the omission of Fe that most affected the development of this species in all parameters evaluated. The treatments negatively affected the chlorophyll content, evaluated in SPAD units, and the photosynthetic rate, except for the omission of B. However this result was probably due to the concentration effect, since there was a significant reduction in the dry matter production of B-deficient plants.

Summary. The growth and ability of 12 summer-growing annual and perennial legumes to fix nitrogen and the response of a subsequent wheat crop was examined in a field trial on a deep cracking clay soil in the Central Highlands of Queensland. Twelve legumes [Lablab purpureus cv. Highworth, Vigna radiata cv. Satin, Macroptilium atropurpureum cv. Siratro, Medicago sativa cv. Trifecta, Vigna trilobata (CPI 13671), Macroptilium bracteatum (CPI 27404), Glycine latifolia (CQ 3368), Desmanthus virgatus cv. Marc, Desmanthus virgatus cv. Bayamo, Stylosanthes sp. aff scabra (104710), Clitoria ternatea cv. Milgarra, Cajanus cajan cv. Quest)] and grain sorghum (Sorghum bicolor cv. Tulloch) as a non-legume control were established in November 1994 and their growth monitored until March 1995. The legumes averaged greater than 5 t/ha dry matter production and 77 kg N/ha (above-ground only). Dry matter production ranged from less than 2 t/ha for G. latifolia and M. sativa to greater than 9 t/ha for D. virgatus cv. Bayamo and C. cajan. Annual legumes initially had much higher relative growth rates than the perennial legumes but they rapidily exhausted all the plant available water content of the soil thus allowing the well-established perennials to eventually match this production. The proportion of plant nitrogen (above ground) derived from N2 fixation was generally low, reflecting high soil NO3, but varied widely between species ranging from less than 20% for D. virgatus cv. Marc and G. latifolia to over 45% for C. ternatea, S. scabra and V. trilobata. The quantity of nitrogen derived from fixation was correlated with above-ground dry matter and nitrogen content. There was a significant (P<0.05) growth response by wheat following legumes compared with that following sorghum in the increasing order V. radiata = M. atropurpureum = L. purpureus > C. cajan = M. sativa = V. trilobata = M. bracteatum = G. latifolia > S. scabra = D. virgatus = C. ternatea. Previous legume growth had no significant (P>0.05) effect on yield or nitrogen concentration in a second ‘plant-back’ crop (sorghum). It was concluded that a wide range of pasture-ley legumes have the potential to improve cereal crop production in this region.

Plant Evaluation

Twenty Urochloa accessions, representing four species, were grown as small swards for a 2 to 4 year period at five sites. The sites cover a wide range of tropical environments. Dry matter production and 'secondary attributes' were observed at strategically important times at the various sites. Various forms of analysis were applied to the resulting information and species, or species forms, of particular agronomic interest were delineated. Two accessions appear to have outstanding potential. The implications of the methods used and results obtained are discussed in relation to plant introduction and plant evaluation programs, and the high potential value of the genus noted.

Zinc Fertilizer

The effectiveness of zinc fertilizer (Zn) on a wide range of Australian soils was examined using subterranean clover (Trifolium subterranean cv. Nungarin) as a test crop in a glasshouse experiment. The initial effectiveness (IE) of zinc fertilizer as measured by dry matter production (DMP), and zinc content (uptake) of subterranean clover (clover) was found to vary markedly among the soil types. No simple linear retationship between the initial effectiveness measured by either dry matter production or uptake and any one soil property was found. IE values were found to be related to the pH (1 : 5 soil :water) (pHw) and the level of DTPA soil extractable zinc measured in the unfertilized soil (Zno). IE based on Zn uptake by clover tops was also related to the organic carbon (OC) (%) content of the soils. The model for IE measured by DMP in a stepwise linear regression was IEDMP = 2.682 - 0.107 pH,-4.852 Zn, (n = 45; r2 = 0-86). IE based on Zn uptake by clover tops was: IEuptake = 10.842 - 0.882 pH, - 0.310 OC (%) - 1.349 Zn, (n = 54; R2 = 0.85). The IE of zinc fertilizer measured by DTPA soil extraction (IEDTPA-zn) was also found to vary markedly among soil types. The level of zinc extracted by DTPA after the addition of Zn fertilizer was found to be affected by clay (%), organic carbon (%) and calcium carbonate (CaCO3) (%) content of the range of Australian soils. This relationship could be described by: IEDTPA - Zn = 0.178 + 0.0.002 Clay (%) + 0.014 OC (%) + 0.018 CaCO3 (%) (N = 54, r2 = 0.84)
