“…Various physiological, morphological and biochemical abnormalities are induced by Zn de fi ciency in citrus plants, which ultimately reduce fl owering, fruit set and yield both quantitatively as well as qualitatively (Srivastava and Singh 2005 ) . Generally, the de fi ciency of Zn in citrus is characterised by occurrence of interveinal chlorosis, which in certain cases is coupled with rosetting.…”

Generally roots not only provide anchorage and support to plants but also help to absorb water and nutrients from the soil. The roots and shoots of plants including citrus are functionally separate but mutually dependent. The roots absorb water and mineral nutrients from the soil and transport to the areal parts including shoots and leaves. In return the shoots supply photosynthates to the roots. Presently the need of absorption of inorganic nutrients through plant leaves has AbstractThe availability of essential nutrients in appropriate amount ensures the growth, productivity and quality for sustainable production of tree fruits including citrus. The essential mineral element below the critical level adversely affects growth and yield even other minerals are within optimum range. A balanced and continuous supply of the essential nutrients is a key for citrus growers to ensure pro fi tability. Soil application is recommended for most of the macronutrients such as N, P and K, as these are required in large quantities. However, the soil application leads to nutrient losses through runoff, leaching and fi xation. Therefore, the foliar application is considered as an attractive alternative to the soil application of essential nutrients. Particularly, the trace elements which are required in small quantity are preferably applied through the foliar sprays. Nutrients applied through the foliar spray are directly absorbed though leaves and have several positive attributes. Foliar application can reduce overall fertiliser application rate and energy use, improve nutrient uptake and reduce underground water pollution. The ef fi ciency of foliar application of nutrients can further be enhanced with the addition of surfactants or adjuvant into the spray solution. Surfactants can be classi fi ed into various groups on the basis of their composition such as cationic, anionic, non-ionic, zwitterionic or ampholytic. The surfactants are widely used in foliar application of both macro-and micronutrients. This chapter reviews the available information about the use of surfactants in the foliar application of mineral elements in citrus with special reference to nitrogen (N), calcium (Ca), iron (Fe), zinc (Zn), boron (B) or copper (Cu).

“…Zn deficiency, in citrus, is described by a number of names such as 'frenched leaf', 'frenching', 'mottle leaf' etc. Zn is undoubtedly the single most desired nutrient, reported to be deficient across the various citrus belts of India (Srivastava and Singh 2005). Citrus apparently has difficulty in absorbing sufficient Zn from many soils, and anything that affects the root system adversely, is likely to reduce the Znintake strikingly (Srivastava and Singh 2005).…”

“…Zn is undoubtedly the single most desired nutrient, reported to be deficient across the various citrus belts of India (Srivastava and Singh 2005). Citrus apparently has difficulty in absorbing sufficient Zn from many soils, and anything that affects the root system adversely, is likely to reduce the Znintake strikingly (Srivastava and Singh 2005). Several studies had been undertaken to understand the effect of Zn on the growth of Citrus plants, but none of them have intended to detect the alterations of physiological, ultrastructural and biochemical parameters under deficiency and excess taken together.…”

“…Chlorosis of sweet orange was mainly due to Zn-deficiency caused by antagonistic effect of Fe on Zn-availability. Accumulation of Zn can occur before visible wilting or reduced water transport [7]. Zinc levels fluctuate seasonally in the wood of diseased and healthy trees.…”

“…Citrus apparently has difficulty in absorbing sufficient Zn from many soils and anything that affects the root system adversely, is likely to reduce the Zn-intake remarkably. With root injury and other mineral deficiencies that may have a pronounced effect on Zn-deficiency too [7] Global occurrence of Zn-deficiency known by various names like rosette, little leaf, mottle leaf etc. is basically characterized by interveinal chlorosis which may or may not be coupled with rosetting or small leaves.…”

ABSTRACT:Citrus reticulata (mandarin) plant parts and soil have been opted for elemental evaluation by INAA with comparator and k 0 method. Two reference material Soil-7 (IAEA) and apple leaves (SRM1515) were used as standards. Sodium was estimated by irradiation of samples in Am-Be source followed by counting on NaI(Tl) detector. Samples were also irradiated in KAMINI reactor, IGCAR, Kalpakkam and radioactive assay was carried out using HPGe detector coupled with 5MCA. Concentration of Na, Al, Mn, Ca, Fe, Sr, Sm, Sc, La, Th, Br, K, Zn, Ce were determined by NAA and in all 15 radicals were identified by XRF for same samples. It has been seen that soil with certain mineralogical and chemical make-up behaves respectively for availability of micronutrients.
