Purpose Rock phosphate (RP) and farm yard manure (FYM) can promote plant growth, but little is known about the effect of sugar juice residues (FMC) on Zn, Cu, Cd, and Pb phyto-availability. This study investigated the effects of FYM and FMC added alone or each in combination with RP on wheat growth and Zn, Cu, Cd, and Pb uptake. Methods Wheat was grown in a soil amended with 0.25, 0.5, or 0.75 g RP or with 5, 10, or 20 g kg-1 soil of FYM, or FMC, added separately, or each in combination with 0.75 g P2O5-RP kg-1 soil. At harvest, shoot N, P, and K; soil pH; available P and DTPA-Zn, Cu, Pb, and Cd, dry matters of root, shoot, and grain; and heavy metals’ concentration in each organ were determined. Results RP addition increased growth and P and K uptake and reduced Zn, Cu, Cd, and Pb of wheat more at the high application rate compared to the low application rate. Compared to the control, FYM addition decreased soil pH, increased P and metals availability and uptake, and decreased plant biomass, whereas FMC addition increased soil pH, decreased P and metals availability and uptake, and increased plant biomass; these effects were maximized with increasing the application rate. Conclusion The results revealed that FMC has the potential in limiting heavy metal uptake and that the combined application of FMC and RP is beneficial for wheat growth.

Lighting regimes are possibly used as a strategy to improve rabbit production in tropical regions; on this background, this study was conducted to assess the possible role of different light (L):dark (D) regimes in improving growing New Zealand white rabbit’s performance. Sixty-four growing rabbits were randomly divided into four groups. Rabbits of the first group (C) were exposed to 12 h of light (from 10.00 to 22.00 h). Rabbits of the second group (T1) were exposed to 12 h of light (from 22.00 to 10.00 h). The third group (T2) was exposed to 8 h of light (from 10.00 to 18.00 h), while the fourth group (T3) was exposed to 8 h of light (from 22.00 to 06.00 h). Temperature-humidity index values ranged between 27.00 and 28.87, indicating exposure of growing rabbits to very severe heat stress.
