A comparative study of Zn and Fe distribution in two contrasting wheat genotypes

Journal of Applied and Natural Science (2018)

Bhupendra Mathpal P.C. Srivastava S. C. Shankhdhar

Effect of zinc and iron interaction on their distribution was examined in two wheat genotypes (UP262 and UP2628) under foliar application of 0, 0.25 and 0.50% ZnSO4 solution tagged with 925 KBq of Zn65 pot-1 for Zn and 0, 0.5 and 1.0% FeSO4 solution tagged with 925 KBq of Fe59 pot-1 for Fe at 30, 60 and 90 days after planting. Maximum grain yield of UP2628 (2.7 g pot-1 ) was recorded at 0.5%ZnSO4+0%FeSO4 while that of UP262 (2.63 g pot-1 ) was recorded at 0.5%ZnSO4+1.0%FeSO4. The highest straw yield of UP2628 (2.75 g pot-1 ) was noted at 0.5% ZnSO4+1.0%FeSO4 while that of UP262 (2.91 g pot-1 ) with 0.5%ZnSO4+0.5%FeSO4. Application of 0.5% and 1.0% FeSO4 reduced the accumulation of 65Zn in all parts of both the varieties. Regarding the 59Fe accumulation, it was found to be decreased with the increased application of ZnSO4 solution from 0.25% and 0.5% as compared to without application of Zn. On comparing translocation efficiencies of both the varieties, UP2628 showed better translocation thus accumulated higher zinc and iron. Therefore, variety UP2628 can be used further for crop improvement programme.

Judicial nutrient management for sustainable production of groundnut: A Review

International Journal of Research in Agronomy (2024)

Sukumar Gorai Mayur S. Darvhankar Bhupendra Mathpal Animesh Ghosh Bag

Groundnut is a leguminous and oilseed crop cultivated throughout the globe due to its excellent nutritional values. Area under groundnut cultivation increased over time though productivity became stagnant and not given the desirable value. Key cause associated with this problem is indiscriminate use of chemical fertilizer which continuously deteriorates soil health and quality. Cultivation through organic inputs is a smatter way to improve soil health but due to population explosion it does not seems a feasible option for developing countries like India. Comprehensive approach should be taken to meet the both end and find a middle way for sustainable production of ground nut over a prolonged period of time. Integrated nutrient management (INM) acts as a bridge between two between two extreme concepts i.e. chemical fertilization and organic farming. INM is getting popular now a days for higher sustainable yield in minimal fertilization. Impact of different fertilizers, organics and integrated approach has been discussed on yield, growth and oil content of ground in this present article through a collective manner.

Exogenous Applied Zinc, Cytokinin and Gibberellic Acid Affecting Growth and Yield of Timely and Late Sown Wheat (Triticum aestivum L.)

Indian Journal of Agricultural Research (2024)

Simarjot Singh Chakravarthy Thejesh Mayur S. Darvhankar Bhupendra Mathpal

Background: Micronutrient deficiency especially of zinc (Zn) impacts wheat growth and yield under both timely sown and late sown conditions. The study investigated the effect of Zn, cytokinin and gibberellic acid (GA) on growth and yield of wheat crop. The design of experiment was split-split plot having three replications. Methods: The main plots were comprised of two varieties i.e., V1 (PBW 725) and V2 (PBW 752) which were divided into three subplots Zn0 (no Zn), Zn1 (62.5 kg/ha soil application of ZnSO4) and Zn2 (31.25 kg/ha Zn in soil+foliar spray of 0.5% of ZnSO4). The subplots were further divided into four sub-sub plots i.e., H0 (no hormone), H1 (10 ppm GA), H2 (10 ppm cytokinin) and H3 (5 ppm GA+5 ppm of cytokinin). Result: The results indicated that the combination of Zn2+H1 resulted in maximum height of plant, accumulation of dry matter and straw yield for both varieties. The reported increment for all three parameters was 8.3%, 15.4% and 18.9% for V1 and 10.1%, 14.9% and 17.4% for V2, respectively. However, for both V1 and V2 a combination of Zn2+H2 improved tiller count, leaf area index and ultimately grain yield. The increment for V1 was 24.4%, 15.2% and 17.1%, while for V2 was 30.1%, 17.2% and 19.3%, respectively. The maximum harvest index value was recorded for variety V2 under Zn2+H2. The correlation analysis showed that leaf area index, number of tillers and dry matter accumulation are strongly correlated with grain yield. In general, the study emphasized that soil+foliar application of Zn alongside 10 mg/L cytokinin was most prominent in improving growth and yield of both wheat varieties.

Enrichment of <sup>65</sup>Zn in two contrasting rice genotypes under varying methods of zinc application

Plant Soil and Environment (2014)

Bhupendra Mathpal P. C. Srivastava Arvind Kumar Shukla Deepti Shankhdhar S. C. Shankhdhar

Zinc (Zn) is an essential micronutrient for growth and development of almost all organisms and its deficiency severely affects the health of plants, animals and humans. In order to investigate the enrichment of Zn in cereals a pot experiment was performed in two contrasting rice varieties viz., PD16 (zinc efficient) and NDR359 (zinc inefficient) under different levels of zinc regimes such as control (0 Zn), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of 65Zn/pot), foliar spray of 0.5% ZnSO4 at 30, 60 and 90 days (925 KBq of 65Zn/pot), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of 65Zn/pot) + foliar spray of 0.5% ZnSO4 at 30, 60 and 90 days (925 KBq of 65Zn/pot). Both varieties markedly differ in 65Zn accumulation and grain Zn content. NDR359 showed poor translocation efficiency and accumulated relatively less 65Zn in all the plant parts. In both rice varieties, highest concentration of Zn in dehusked grains could be obtained with soil application of Zn + foliar spray of zinc sulphate. Though NDR359, a zinc inefficient variety exhibited poor zinc translocation efficiency yet, it contained more Zn content in grains with husk and dehusked grains than PD16.

Zinc enrichment in wheat genotypes under various methods of zinc application

Plant Soil and Environment (2015)

Bhupendra Mathpal P. C. Srivastava Deepti Shankhdhar S. C. Shankhdhar

Around half of the cereal growing soil in the world are zinc (Zn)-deficient and it severally affects the health of plants, animals and humans. In order to investigate the enrichment of Zn in cereals a pot experiment was conducted in two contrasting wheat genotypes viz., UP2628 (Zn efficient) and UP262 (Zn inefficient) under different methods of Zn application such as control (0 Zn), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of 65Zn/pot), foliar spray of 0.5% ZnSO4 at 30, 60 and 90 days (tagged with 925 KBq of 65Zn/pot), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of 65Zn/pot) + foliar spray of 0.5% ZnSO4 at 30, 60 and 90 days (tagged with 925 KBq of 65Zn/pot). Cultivars showed marked difference in 65Zn accumulation and grain Zn content. In both contrasting genotypes the highest Zn content in grains was recorded under soil application + foliar spray of Zn fertilizers. Both UP262 and UP2628 showed similar accumulation of 65Zn in leaves however, UP2628 exhibited better translocation efficiency and accumulated higher 65Zn in stem and grains than UP262.

Zinc mediated enhancement of key enzyme activities in leaves and protein content of wheat grain

Israel Journal of Plant Sciences (2024)

Bhupendra Mathpal P.C. Srivastava Aradhana Kumari S. C. Shankhdhar

Abstract Zinc (Zn) deficiency is a widespread problem in agricultural soils all over the globe. As an essential element, Zn plays a decisive role in realization of high yields of wheat, the changes in activities of Zn dependent enzymes and its accumulation in various plant parts of wheat varieties of differential susceptibility. The aim of the study was to examine the activities of Zn dependent enzymes, i.e. superoxide dismutase (SOD), carbonic anhydrase (CA); chlorophyll and grain protein content and to evaluate the pattern of Zn transport in two wheat varieties (UP2628-Zn efficient and UP262-Zn inefficient). All these parameters were evaluated in a pot experiment under different modes of Zn applications viz ., control (C), soil application (S), foliar application (F), soil+foliar application (S+F). The accumulation of Zn in different plant parts of both wheat varieties under different Zn supply regimes was monitored in a separate autoradiography experiment where radiolabelled Zn was used. An increased activity of SOD, CA and total chlorophyll content in leaves, high protein content in grains and 65 Zn accumulation was observed under S+F mode of Zn application. Zinc efficient variety (UP2628) showed higher SOD, CA activities, chlorophyll content in leaves and grain protein content as compared to UP262. Both soil application + foliar spray of Zn and cultivation of Zn efficient variety (UP2628) can be best approach for Zn biofortification of wheat.
