    Notes: Summary The effect of N and Zn on the yield of submerged rice and uptake of N and Zn was studied on limed and unlimed soils in greenhouse. Nitrogen was applied at the rate of 0,80 and 160 ppm through urea, ammonium sulphate and ammonium nitrate, Zn at 0 and 10 ppm in limed (4% CaCO3) and unlimed soils. Liming (4% CaCO3) decreased dry matter yield of rice at tillering, heading and straw and grain at maturity significantly against unlimed treatments. Ammonium sulphate gave highest yield with all applied doses followed by ammonium nitrate and urea. Zinc at 10 ppm increased dry matter and grain yield significantly over no Zn treatment in rice. The N sources gave N concentration and uptake in rice plants in decreasing order: $$Ammonium sulphate 〉 Ammonium nitrate 〉 Urea.$$ The highest N concentration was recorded with 160 ppm followed by 80 ppm N through any source and lowest in control. The application of Zn increased and liming decreased N concentration and uptake by rice at all sampling stages. Highest N concentration (2.37 to 3.92%) was observed at tillering followed at heading (0.48 to 1.05%). At maturity N in grain ranged from 0.69 to 1.13% whereas in straw from 0.24 to 0.41%. There were positive significant interactions of N(S) x N(L), N(S) and N(L) x Zn and negative interaction with lime on yield, N concentration (%) and N uptake (mg/pot). The application of N sources and levels and Zn increased Zn uptake (μg/pot), and liming decreased it. But 160 ppm N through any source decreased straw Zn concentration over 80 ppm N in absence of added Zn, however, effects on grain were not so strong particularly that of 160 ppm, when 10 ppm Zn was also added even 160 ppm N increased Zn concentration over 80 ppm significantly in both straw and grain. In this case the effect of N sources on Zn concentration was in the order: $$Ammonium sulphate 〉 Urea 〉 Ammonium nitrate.$$

    Notes: Summary The effects of Zn, P, N and CaCO3 on tryptophan concentration in rice grain were studied in greenhouse at Haryana Agricultural University. Zinc application upto 20 ppm increased tryptophan concentration in rice grain. Zn-EDTA gave highest increase followed by ZnSO4 and then ZnO. Liming at the rate of 4 and 8 per cent decreased tryptophan concentration significantly. Phosphorus application upto 100 ppm also decreased tryptophan significantly but Zn in combination with P increased tryptophan and overcame negative effect of P. Nitrogen application upto 120 ppm increased tryptophan concentration. There was positive interaction between Zn and N. Ammonium sulphate gave highest tryptophan followed by ammonium nitrate and then urea. The tryptophan concentration ranged between 766 ppm and 2011 ppm in paddy grain. The lowest tryptophan concentration was in the plants treated with 8 per cent lime in absence of added Zn and highest with 10 ppm Zn through Zn-EDTA.

    Notes: Summary Boron, copper, iron, manganese and zinc concentrations were measured in sunflower leaves from plants grown hydroponically in a closed continuous flow system and with boron concentrations ranging from deficient to toxic. Leaves were analyzed at the stage of flower development. There was a highly significant inverse correlation between B concentration in solution and Mn concentration in leaves. Cu, Fe and Zn concentrations in the leaves were not changed by the different B levels, although the B concentration in leaves increased with an increasing concentration in solution, showing a close correlation each other.

    Notes: Summary Self-diffusion coefficients of zinc and iron were determined in acid soil of Palampur and alluvial soil of Ludhiana under varying pH, CaCO3, moisture, carrier and phosphorus levels. Increase in pH caused tremendous reductions in self-diffusion coefficients (Da) of both zinc and iron in soil. The selfdiffusion coefficients of both these elements were drastically reduced as a result of CaCO3 application. The Da values of zinc and iron increased with the decrease in moisture tension and increase in carrier and phosphorus levels. The decrease in Da values were associated with increase in capacity factor.

    Notes: Summary Studies were conducted in 22 non-calcareous soils (India) to evaluate various extractants,viz. (6N HCl, 0.1N HCl, EDTA (NH4)2CO3, EDTA NH4OAc, DTPA+CaCl2 and 1M MgCl2) to find critical levels of soil and plant Zn for green gram (Phaseolus aureus Roxb.). The order of extractability by the different extractants was 6N HCl〉0.1N HCl〉EDTA (NH4)2CO3〈EDTA NH4OAc DTPA+CaCl2〉1M MgCl2. Critical levels of 0.48 ppm DTPA × CaCl2 extractable Zn, 0.80 ppm EDTA NH4OAc extractable Zn, 0.70 ppm EDTA (NH4)2CO3 extractable Zn, and 2.2 ppm 0.1N HCl extractable Zn were estimated for the soils tested. The critical Zn concentration in 6 weeks old plants was found to be 19 ppm. The 0.1N HCl method gave the best correlation (r=0.588**) between extractable Zn and Bray's per cent yield, while with DTPA+CaCl2, it was slightly low (r=0.542**). The DTPA + CaCl2 method gave significant (r=0.73**) correlation with plant Zn concentration. The 0.1N HCl gave the higher correlation with Zn uptake (r=0.661**) than DTPA (r=0.634**) 6N HCl and 1M MgCl2 method gave nonsignificant positive relationship with Bray's per cent yield. For noncalcareous soils apart from the common use of DTPA+CaCl2, 0.1N HCl can also be used for predicting soil available Zn. The use of 0.1N HCl would be much cheaper than DTPA and other extractants used in the study.

    Notes: Summary Cucumber (Cucumis sativus) plants were grown in Hoagland solution to which 20 to 2000 ppm of a soil fulvic acid (FA) were added. The addition of 100 to 300 ppm of FA produced highly significant increases in the growth and development of above and below ground plant parts, in the uptake of nutrient elements (N, P, K, Ca, Mg, Cu, Fe and Zn), and in the formation of numbers of flowers per plant. Effects of adding 500 and more ppm of FA were less beneficial.

    Notes: Summary Effect of amendments, gypsum (12.5 tonnes/ha), farmyard manure (30 tonnes/ha), rice husk (30 tonnes/ha) and also no amendment (control) on the availability of native Fe, Mn and P and applied Zn in a highly sodic soil during the growth period of rice crop under submerged conditions was studied in a field experiment. Soil samples were collected at 0, 30, 60 and 90 days of crop growth. Results showed that extractable Fe (1N NH4OAC pH 3) and Mn (1N NH4OAC pH 7) increased with submergence upto 60 days of crop growth but thereafter remained either constant or declined slightly. Application of farmyard manure and rice husk resulted in marked improvement of these elements over gypsum and control. Increases in extractable Mn (water soluble plus exchangeable) as a result of submergence and crop growth under different amendments were accompanied by corresponding decreases in easily reducible Mn content of the soil. Application of 40 kg zinc sulphate per hectare to rice crop could substantially raise the available Zn status (DTPA extractable) of the soil in gypsum and farmyard manure treated plots while the increase was only marginal in rice husk and control plots indicating greater fixation of applied Zn. Available P (0.5M NaHCO3 pH 8.5) behaved quite differently and decreased in the following order with crop growth: gypsum〉rice husk〉farmyard manure〉control.

    Notes: Abstract In pot experiments the relationships between rhizosphere pH, the extractable levels of Fe, Mn and Zn in the soil and their uptake into the roots and shoots of dwarf French beans have been studied. Variations in rhizosphere pH were induced by applying three different sources of nitrogencholine phosphate, ammonium phosphate and calcium nitrate-to an initially homogenised soil (preadjusted to either pH 7 or 8). The rhizosphere pH was found to be significantly lower following the application of either ammonium or choline phosphates and to be increased by calcium nitrate treatment. The Fe and Zn contents of both shoot and root were inversely proportional to rhizosphere pH. The Mn contents also increased with decreasing pH but a sharp increase was apparent below pH 5.5. The shoot Fe, Zn and Mn content were significantly correlated with the extractable levels determined in the rhizosphere and non-rhizosphere soil.

    Keywords: Cobalt ; Copper ; Iron ; Manganese ; Plant uptake ; Trace metals ; Waterlogging ; Zinc

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The uptake of trace metals by two plant species (French bean and maize) has been measured on two soils subjected to various waterlogging regimes. Uptake of both manganese and iron was increased due to soil waterlogging, although reoxidation of the soil affected iron more than manganese. Zinc and copper uptake was influenced by a species factor; French bean (Phaseolus vulgaris) showed preferential uptake of zinc, whereas maize (Zea mays) took up copper preferentially. Uptake of cobalt by both species was increased due to waterlogging, following the pattern of manganese. The abilities of these species to take up trace metals from soil followed the pattern predicted by selective extraction of soil for manganese, iron and cobalt, but not for zinc and copper.

    Notes: Summary The feasibility of zinc supply to apples (Malus spp. var. Golden Delicious) by various Zn-bentonite preparations implanted in the trunk was studied. A preliminary experiment included four preparations and was conducted in one plantation in 1980. A larger scale experiment in 1981, tested Zn-bentonite (ZnB) and Zn-bentonite + ZnEDTA (ZnBEA) in four plantations in the south, center and north of Israel. Clay tablets were implanted in holes drilled in the tree trunk in April. The youngest, fully developed leaves on the new growth were sampled periodically and Zn content was determined. ZnB and ZnBEA implanted at the rate of 15 mg Zn/cm trunk circumference significantly increased Zn content above that of the control trees until mid-September. The ZnBEA preparation supported significantly higher leaf concentrations than the ZnB preparation. Peak concentrations in trees treated with the ZnBEA preparation were 75.8, 47.4, 38.4, and 23.7 ppm in the four plantations and occurred in May. The Zn concentration in the youngest leaves decreased during the season but there was evidence that in some cases Zn behaved as a phloem mobile element. Soil, climate and previous zinc treatments affected considerably the Zn concentration found in leaves in the four plantations making it impossible to identify a single critical concentration level. No damage to the trees was observed as a result of the drilling and implantation of the clay tablets. Clay analysis at the end of the season showed that about two-thirds of the Zn added to the trees was used. The amount of Zn supplied per tree in the implantation procedure was 80–90% lower than that supplied in the routine spraying operations.
