Effect of Zinc Application on Zn Content and Uptake in Grain, Husk and Straw of Hybrid Rice (Oryza sativa L.)

Effect of Zinc Application on Zn Content and Uptake in Grain, Husk and Straw of Hybrid Rice (Oryza sativa L.)

Effect of zinc application on yield, zinc biofortification of grain and use efficiency in rice (Oryza sativa L.)

Micronutrient deficiencies or ‘hidden hunger’ particular for zinc (Zn) deficiency affect more than 270 million people worldwide and about one-third population of the world is residing in the developing countries. Globally, rice is a staple food of the population and grown approximately 90% in south, south-east and east-Asia, which is inadequate soil Zn level and ultimately causes dysfunctional food system and unbalanced diets. Therefore, the present field experiment was undertaken to study the effect of agronomic Zn fertilization on grain yield, grain Zn and efficiencies of five rice varieties viz., Pusa Basmati 1121, Pusa Basmati 1509, Sugandh 5, CSR 43 and CSR 30. A field study resulted that Pusa Basmati 1121 and Pusa Basmati 1509 were found better for improvement of grain Zn, while Pusa Basmati 1509 and Sugandh 5 for yield in response to Zn fertilization. The effect of 50 kg/ha soil Zn application on grain yield of Pusa Sugandh 5 was recorded highest during both the years of study during 2015 and 2016 and was significantly superior to other four varieties. For the human and animal nutrition points of view, zinc fertilization in rice cultivars is an important cost-effective approach, reduces Zn malnutrition and it can save the life of millions of people in Asian countries.

Effects of Zinc Application on Yield and Some Yield Components in Peanut (Arachis hypogaea) in the Easthern Mediterranean Region

The effect of soil and foliar Zn fertilization on two varieties of peanut’s ( Arachis hypogaea ) yield and some yield components were examined in this study. Soil applications of Zn doses were 0, 10, 20 and 40 kg ha -1 whereas 0, 0.5, 1 and 1.5 kg ha -1 Zn were sprayed to leaves. Applications of dose amounts of Zn lead to remarkable increase in yield and 100-seed weight. The effect of Zn treatment found to be statistically important at P<0.01 levels. The highest yield was obtained at COM variety as 6580.0 kg ha -1 with 0.5 kg ha -1 Zn foliar application. The lowest yield was measured at NC-7 variety’s control plot with 3660.0 kg ha -1 in 2007. Foliar application Zn was statistically determined to be important to NC-7 variety peanut’s grain Zn concentration at P<0.05 levels in each year. The economic analyses revealed that 0.5 kg ha -1 foliar application of Zn provided maximum profit with 10271.2 USD Dollars ha -1 .

Effect of Zinc Application on Cadmium Uptake of Maize Grown in Alkaline Soil

The aim of this research is to investigate the effect of zinc (Zn) application on cadmium (Cd) uptake of maize (Zea mays L.) grown in alkaline soil. Four doses of cadmium (Cd; 0, 2.5, 5, and 10 ppm) in the form of cadmium chloride and four doses of Zn (0, 10, 20, and 40 ppm) in the form of zinc sulfate were applied to the soils. Plants were harvested at the 45th day of their developments. The Cd amounts in shoots and roots were analyzed separately. Significant differences between Cd amounts in shoots and roots are obtained with the application of different Zn doses (P < 0.01). In all Cd levels, Zn application increases Cd in both shoots and roots relative to Cd contents of plants grown in the pots that not applied Zn. It is also found that Cd content of the roots is greater than that of shoots.

Effect of Zinc Application on Growth and Some Biochemical Characteristics of Costmary (Chrysanthemum balsamita L.)

A pot experiment was conducted to investigate the effects of different zinc (Zn) application methods (soil and foliar application) and concentrations (1 and 2 mg kg−1 in soil application and 1 and 3 g L−1 in foliar application) on the growth, some biochemical characteristics, and nutrient concentrations of costmary (Chrysanthemum balsamita L.). Growth parameters were increased by zinc application regardless of its concentration and application method. Protein and total phenol content, antioxidant capacity, and chlorophyll index were increased by zinc supply. In contrast, proline and soluble sugars content showed a decreasing pattern with zinc application. Zinc application, either through soil or foliar application, increased the zinc content of shoots. Manganese uptake potential of plants was increased by foliar zinc application method but not by soil application of zinc. Zinc application had no significant effect on potassium content of plants.

Effect of Zinc Application on Rice Yield under Wheat Rice System

A field experiment was conducted during 2004-05 on wheat and rice to study the response of Zinc application in wheat-rice system. Two levels of zinc 5 and 10 kg ha(-1) with control were studied with the basal dose of N, P2O5, K2O as 120-90-60 kg ha(-1) in the form of urea, TSP, SOP and zinc sulphate during both the crops. Wheat variety Naseer 2000 and rice variety IRRI 6, both were planted in R.C.B design with three replications. Zn application, significantly affected wheat grain yield, ranged from 2.7 to 3.5 t ha(-1), giving highest increase of 31.6% over control from 5 kg Zn ha(-1). The number of tillers, spike m(-2), spike length, plant height and 1000 grain weight of wheat were also significantly affected over control with the same treatment. Paddy yield was also significantly affected by Zn levels ranged from 3.9 to 5.9 t ha(-1). The highest yield was obtained from 10 kg Zn ha(-1) each applied to both crops. Similarly Zn application also affected significantly to the yield parameters of rice like the number of spike m(-2), number of spike/plant, spike length, plant height and 1000 grain weight over control from the above said treatment of 10 kg Zn ha(-1). The concentration of zinc in soil and leaves was significantly affected by the application of zinc in wheat and rice, ranged from 0.47-1.37, 22.6-367.37 mg kg(-1) in wheat and 0.45-1.18; 29.32-40.67 mg kg(-1) in rice, respectively (soil and leaves). The highest concentration in soil and leaves was recorded by the cumulative application of 10 kg Zn ha(-1) while lowest from control. The direct application of 5 and 10 kg Zn ha(-1) gave an increase of 39 and 45% while residual effect 30.0 and 43.0%, cumulative effect of 38 and 50% over control, respectively. The residual application of 10 kg Zn ha(-1) can be recommended for economical production in wheat rice system.

Aplicação de zinco via sementes e seu efeito na germinação, nutrição e desenvolvimento inicial do sorgo

O objetivo deste trabalho foi avaliar o efeito da aplicação de zinco em sementes de sorgo (Sorghum bicolor (L.) Moench) na nutrição, na germinação e no desenvolvimento inicial das plantas, em casa de vegetação. Utilizou-se delineamento inteiramente casualizado dos tratamentos, em esquema fatorial 2x5, duas cultivares de sorgo (BR 304 e BR 310) e cinco doses de Zn (0, 3,57, 7,14, 14,28 e 28,56 g de Zn por kg de sementes), com três repetições. Foram avaliadas as variáveis de germinação (tempo médio, média diária e a velocidade), e 28 dias depois da semeadura, determinou-se a massa da matéria seca e os teores de Zn na parte aérea e nas raízes. A aplicação de Zn nas sementes de sorgo não afetou o acúmulo de matéria seca da parte aérea, entretanto, diminuiu a germinação e o acúmulo de matéria seca das raízes e da planta inteira. O Zn aplicado nas sementes de sorgo acumulou-se principalmente nas raízes. A cultivar BR 304 apresentou maior absorção de Zn e acúmulo de matéria seca, em relação à cultivar BR 310.

The effect of Zinc application on the methods which can be used to determine available Iron content of soils

This research was carried out in order to find out the effect of zinc application on the methods which can be used to determine available iron content of paddy soils. For this purpose, an experiment was carried out in greenhouse conditions by growing maize. The effect of increasing rates of zinc application on biological indexes of maize plants was determined. Eight chemical extraction methods for available iron content of soils were used and these methods are: 0.005 M DTPA+0.01 M CaCl2+0.1 M TEA; 0.005 N HCl+0.025 N H2SO4; 1 N NH4Oac; 0.01 N Na2EDTA+1 N NH4Oac; 2 N MgCl2; 0.01 M Na2EDTA +1 M (NH4)2CO3; 0.01 N Na2EDTA and 0.005 M DTPA+NH4HCO3. The relationships between biological indexes and chemical extraction methods were determined at the end of the experiment. The highest correlation coefficient was determined with the method 0.005 M DTPA+0.01 M CaCl2+0.1 M TEA. The iron content of maize plants decreased with zinc application and dry matter content increased with zinc application.

Resposta de mudas de goiabeira à aplicação de zinco

O subsolo, normalmente utilizado para produção de mudas de frutíferas, apresenta baixa concentração de zinco e, assim, existe grande probabilidade de resposta à aplicação deste micronutriente. Considerando a falta de informações sobre o assunto, procurou-se avaliar o efeito da aplicação de zinco ao substrato de produção das mudas de goiabeira e acompanhar os efeitos no desenvolvimento, na produção de matéria seca e no estado nutricional das plantas. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e cinco repetições. As doses de zinco, na forma de sulfato de zinco, foram: 0; 2; 4; 6 e 8 mg dm-3 de Zn. No plantio, as mudas receberam doses de N, P, K e B de 300; 100; 150 e 0,5 mg dm-3, respectivamente. O experimento foi conduzido em viveiro telado, em vasos com 2,8 dm³ de substrato de um Argissolo Vermelho-Amarelo. Após 135 dias do plantio, avaliaram-se: a altura, a área foliar e a matéria seca da parte aérea e das raízes, bem como os teores de macronutrientes e de Zn. As mudas de goiabeira responderam positivamente à aplicação de zinco. O maior desenvolvimento das mudas esteve associado à dose de 2 mg dm-3 de Zn. Doses iguais ou superiores a 4 mg dm-3 causaram redução significativa no desenvolvimento e no acúmulo de macronutrientes nas mudas de goiabeira.

Effect of zinc application on productivity, nutrient uptake and economics of wheat (Triticum aestivum) varieties under different sowing conditions

A field experiment was conducted during the winter seasons of 201314 and 201415 at the Indian Agricultural Research Institute, New Delhi, to study the effects of sowing time and zinc application on productivity, nutrient up- take and economics of wheat [Triticum aestivum (L.) emend. Fiori &amp; Paol.] varieties. The experiment was laid out in a split-plot design, replicated thrice with sowing times (normal and very late) and wheat varieties (HD 2967, WR 544 and HD 3059) in mainplots and ZnSO .7H O application (control; 25 kg/ha soil application, 3 foliar 4 2 sprays @ 0.5% at boot, anthesis and grain-filling stage; 25 kg/ha soil application + 1 foliar spray @ 0.5% at anthe- sis) in subplots. Very late sowing reduced the yield attributes, grain and straw yields (9.2 and 29.1%), total N, P, K, Zn uptake, net returns (22.9%) and benefit: cost ratio (23.3%) of wheat. HD 2967 wheat gave higher grain and straw yields and showed higher total N, P, Zn uptake, net returns and benefit: cost ratio. However, it showed the highest grain yield reduction (18%) with the late planting. Application of Zn did not significantly alter yield at- tributes, grain and straw yields, net returns and benefit: cost ratio, though this treatment increased the total N, K and Zn uptake (6.8, 5.4, and 9.9% respectively) over the control under 1.45 mg/kg soil available Zn.

DIPA extractable zinc at 1.5 ppm was found to be critical level of zinc for calcareous soils of Coimbatore district with regard to sorghum crop.

Effect of zinc application on the dry matter yield uptake and distribution of zinc and other micronutrients in cocoa (Theobroma cacao. L.)

Abstract The effects of application of zinc fertilizer on dry matter yield, uptake and distribution of zinc and other nutrients by Amazon and Amelonado cocoa cultivars grown in a soil of low zinc content in the greenhouse were investigated. There was a differential response to zinc fertilization by the two cocoa cultivars. Maximum dry matter yields of Amazon and Amelonado were attained with 10 ppm Zn and 50 ppm Zn, respectively. Under similar experimental conditions Amelonado seedlings expressed zinc deficiency symptoms whereas Amazon did not. Zinc concentrations in the leaves, stem and roots of both cuitivars did not give a good index of the zinc status of the crops. This was because of the existence of the “Piper‐Steenbjerg”; effect in that nil zinc rates often gave higher leaf concentration of the zinc than next higher rate. In general, the relative content of zinc followed the pattern; leaves > roots > stem with the Amazon cultivar containing more zinc than the Amelonado. The distribution of absorbed Cu in the leaves, stem and roots did not differ in both varieties. Whereas Fe uptake was mostly concentrated in the roots, Mn absorbed was largely concentrated in the leaves of both varieties and only Mn uptake in the leaves of Amazon consistently increased with Zn application. The differences in the uptake and distribution of nutrients between the two cocoa cultivars was attributed to differences in their ability to extract nutrients from the soil and in their requirements for metabolic processes.

Plant response to micronutrients

The effects of zinc application on zinc uptake, distribution and translocation in maize and barley grown in zinc deficient soil with high pH and high calcium content were studied. Zn65 content and uptake in roots, sheaths and blades of maize and barley plants increased significantly with increased levels of zinc application. The sheaths contained highest Zn65 content followed by roots and blades. The distribution of total zinc, however, differed from that of radioactive zinc. The roots had the highest zinc content, followed by sheaths and blades. The two species differed very little in zinc distribution patterns. The autoradiographs of intact maize and barley plants showed that Zn65 was fairly evenly distributed in the main and auxiliary roots, but, there was a relatively higher concentration at the root-stem junction. The Zn65 concentration was higher in nodes than in internodes, and in young emerging leaves compared to older leaves. re]19730819
