Iron Sulphate

A severe iron deficiency in peas grown on grey to black clay loam soil overlying limestone (rendzina) was successfully ameliorated by foliar application of ferrous sulphate. Two applications, three weeks apart, increased the fresh weight of peas harvested by more than 100 per cent (P < 0.001). The two sprays also increased the numbers of pods, dry weight of the pods, fresh weight per pea and maturity of the peas (all P < 0.001), and herbage yield (P < 0.01). One application of iron sulphate was insufficient to arrest completely the symptoms of iron deficiency. The peas did not show vegetative or marsh spot symptoms of manganese deficiency, and there were no significant changes in measurements to manganese sprays.

Ameliorative Effect

In present study, different foliar treatments were applied on peanut to check their ameliorative effect on Fe deficiency. In hydroponics experiments, foliar applications of FeSO4, Fe-EDTA, sequestrene and ferric chloride were applied to check their effect on Fe deficiency chlorosis in two varieties of peanut already screened as BARI-2000 (Fe deficiency tolerant) and BARD-699 (Fe deficiency sensitive). Sequestrene proved to be more effective in increasing the growth of plant. Photosynthetic rate increased up to 58 and 70% in BARI-2000 and BARD-699 respectively as compared to control with foliar application of sequestrene. Similarly higher active Fe concentration was recorded in both genotypes. Up to 14 and 41% increase in active Fe concentration was observed. Various morpho physiological parameters including root length, shoot length, root fresh weight, root dry weight, shoot fresh and shoot dry weights, SPAD values, photosynthetic and transpiration rates showed that BARD-699 was more responsive to foliar applications, while foliar application of sequestrene can be used in correcting Fe deficiency in both genotypes. Active Fe was significantly correlated with different morphological parameters in both genotypes. The results of presense experiment suggested that foliar applications were helpful in correction Fe deficiency in peanut and growth can be enhanced.

AbstractAmendment of soil with biochar has been shown to enhance fertility and increase crop productivity, but the specific influence of biochar on soil workability remains unclear. Select physico-mechanical and chemical properties of clay loam and sandy loam soils were measured after amendment with wood-derived biochar of two particle size ranges (0.5-425 and 425-850 µm) at five dosages ranging from 0.5 to 10% dry weight. Whereas the clay loam soil workability decreased when the finer wood-derived biochar was applied at rates of 6 or 10%, soil fertility was not enhanced. The sandy loam soil, due to Proctor compaction, significantly decreased in bulk density with 6 and 10% wood-derived biochar amendments indicating higher soil resistance to compaction.

(1) Background: Plants act as the natural sink for a variety of toxins in the environment, including veterinary antibiotics (VAs). The objective of this study was to evaluate the uptake and fate of sulfadimethoxine (SDZ), oxytetracycline (OTC), and streptomycin (STR) in lettuce (Lactuca sativa L.), carrot (Daucus carota), and pepper (Capsicum annum) grown in VAs amended soil. (2) Methods: 0, 50, and 100 mg kg−1 VA laced manure was applied in a sandy clay loam soil. (3) Results: 30-d (lettuce) and 60-d (carrot and pepper) greenhouse experiment showed that SDZ and OTC were taken up by all three plants, with concentrations in plant tissue ranging from 0.1 to 1.2 mg kg−1 dry weight. The concentration of VAs in plant tissues increased with a corresponding increase of antibiotics in manure. The highest plant tissue concentrations were found in carrot and lettuce, followed by pepper. An increase in NADPH P450 reductase and glutathione-s-transferase enzyme activity with increasing SDZ and OTC concentration was evident, signifying the induction of the detoxification process. The activity of plant detoxification enzymes under STR treatment was found not to be significantly different from control. (4) Conclusions: These results raise potential human health concerns of consuming low levels of antibiotics from produce grown on manure-amended soils. The result indicates that SDZ, OTC, and STR antibiotics posed high, medium, and low acute ecological risks in lettuce, carrot, and pepper plants when grown in sandy clay loam soil.

A field experiment was conducted to investigate the effect of foliar application of DAP and TSP on yield and yield attributing characters of lentil. Foliar application of DAP and TSP was performed at flowering and pod formation stages of lentil. Results revealed that maximum fresh weight of plant, nodule number and dry weight of nodule were recorded in F2 treatment at 50% flowering stage of lentil. F1 treatment produced higher branch plant-1 (2.66), pod plant-1(106.47) and seed yield (0.72 t ha-1) of lentil. DAP increased 6% higher grain yield than no foliar application of fertilizer. It may be suggested that foliar application of DAP is a better technology for increasing lentil production in drought prone area of Bangladesh.

SUMMARYExperiments were made on a sandy clay loam soil with five crops to determine the effects of thorough loosening of the subsoil and deep incorporation of nutrients on yields during the subsequent 4 years.Loosening to 0·9 m increased fresh-weight yields by between nil and 95% depending on the crop and season. Responses were still considerable 4 years after the initial loosening and there was no evidence of any decline with time. Deep incorporation of nutrients did not improve yields.Loosening gave a durable increase in the volume of coarse pores and decreases in bulk density and penetrometer resistance. It also nearly doubled the rate of root extension when estimates were made for one crop, consistently increased water extraction from below 30 cm and, on occasion, reduced plant water stress.It is concluded that most of the benefits from deep loosening resulted from improvements i the rate at which plants could extract water rather than nutrients from the subsoil.

Mature `Kerman' pistachio (Pistacia vera L.) trees, located on the west side of the San Joaquin Valley of California on an alkaline clay-loam soil, were fertigated in 1997 and 1998 with three combinations of zinc (Zn) and copper (Cu) sulfate. Seasonal applications of Zn and Cu were injected at three separate times starting in spring and ending in summer. Efficacy of the treatments were compared by measuring the concentration of Zn and Cu in leaf tissue. Fertigated treatments were compared to trees receiving no supplemental Zn or Cu and to trees receiving a single foliar treatment of Zn and Cu each year. Soil Zn and Cu concentrations increased in the fertigated plots. Plots receiving the highest rates of Zn and Cu showed the greatest increase. However, at the recommended August leaf sampling period, only the foliar treated pistachio trees showed a significant increase in leaf Zn and Cu. The results demonstrate that after two seasons, a foliar application of Zn and Cu in April, two to three weeks after flowering, increased leaf-tissue concentrations of Zn and Cu to sufficiency levels. These foliar applications were more effective than fertigating with Zn and Cu sulfate.
