- Abstract:
- ... Nineteen soybean genotypes (ten from the former USSR, two from Brazil and seven from USA) were tested for aluminum (Al) tolerance by growing them for 21 days in greenhouse pots of acid, Al-toxic, unlimed Tatum (Typic Hapludult) subsoil at pH 4.0 and in limed subsoil at pH 5.1. Aluminum tolerance ranking depended upon the plant traits used in the screening process. Based on absolute dry shoot weigh ...

- Abstract:
- ... Recently several claims of copper (Cu) contamination in the lower reaches of the Sado River in the Alcacer do Sal region of Portugal (a major rice producing area) have been reported. In an attempt to study the effect of excess Cu on protein contents without anthropogenic interventions (amendments with fertilizers and sludges, application of pesticides, etc.), rice (Oryza sativa L.) plants were gro ...

- Abstract:

L.) cultivars originated from various tropical countries were subjected to six levels of aluminum (Al) [0, 74, 148, 222, 296, and 370 micromolar] to test their tolerance to Al toxicity in nutrient solutions at pH 4.0 -/+ 0.1. Seedlings were grown in the presence of Al under controlled environmental conditions in growth chambers. The nutrient solution ...

The rice cultivars exhibited a wide range of response by changing the rhizosphere pH, and the uptake and efficiency ratio (ER) of utilization of nutrients both in the presence (222 micromolar Al) and absence of Al. In the presence of Al, the c ...

The influence of N source [potassium nitrate (KNO3)+ native soil N versus rhizobium-inoculated seed + native soil N] and phosphorus (P) (O and 200 mg P/kg), and Zn fertilizers (0, 1, and 8 mg Zn/kg) on growth and nutrient ...

Soil salinity (EC, 3.6 mS/cm) reduced seedling establishment by 77%, and dry matter and grain yields per plant by 32%; grain yield/ha was reduced by 84%. Salinity reduced grain number per head, but not individual gr ...

- Abstract:
- ... Combined nitrogen [nitrate (NO3-), ammonium (NH4+), and urea] will inhibit all components of symbiotic nitrogen (N2) fixation if present in sufficient concentrations. It is generally accepted that nitrate is particularly inhibitory to nodule growth and nitrogenase activity, and somewhat less inhibitory to the infection process. This project examined whether providing low (0.1 - 0.5 mM) static conc ...

The effect of pH on growth and uptake of Cu by Swingle citrumelo rootstock seedlings were investigated in solution culture with varying Cu activities. Copper activities of either 0.05, 0.5, 5, and 10 micromolar at pH 5 and 6 were maintained by adding copper sulfate (CuSO4) to the hydroponic solution based on the calcul ...

Levels of applied fertilizer can affect development of crops such as banana squash (Curcubita maxima Duch.). Seed were planted in 1990, 1991, and 1992 into beds treated with sufficient fertilizer to raise the residual nutrient levels to the recommended (base) and twice recommended (2X ...

It was found that a relationship exists between the galanthamine content of the plant and the chemical composition of the soil. These results indicate that galanthamine bio-synthesis could be controlled by the soil fertility level. ...

Radioactive phosphorus (32P) was used as the marker. The presence of either Cl and SO4 alone in the nutrient solution made no difference on the impairment. Both ions also inhibited the long-distance transport of P from roots to shoots ...
