Effect of zinc nutrition on morphological characters in chickpea

Legume Research, 2015

The comparative effect of 0, 0.2, 0.4, 0.6 and 0.8% Zn levels of zinc chelate (Zn-EDTA; 8% Zn) and zinc sulfate (23% Zn) applied as foliar sprays for assuaging zinc deficiency of chickpea cv. Gökçe was evaluated under field condition. The sprays were applied on the plants before blooming stage during 2012 and 2013 growing seasons and seed yield, yield components like plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and mineral concentrations (nitrogen, phosphorus, zinc and iron) in seeds were investigated. Plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and seed yield were investigated. The results showed that increased zinc doses caused an increase in Zn content of seed, while seed yield was not affected similarly. In general, plant height, pod number and seed number per plant increased by the application of zinc. Lower dose of Zn-EDTA and higher dose of ZnSO 4 gave higher yield components. Seed weight, harvest index and seed yield were not significantly influenced by Zn sources and doses; however, mineral concentration of seeds enhanced when Zn doses were increased. It was concluded that foliar application of zinc resulted in an increase in seed mineral contents rather than seed yield of chickpea. The dose of 0.6% with Zn-EDTA was the optimum combination for Zn enrichment in seed of chickpea.

Background: Pulses are wonderful gift of the nature to agriculture. They provide nutrition to human beings and animals as food and feed respectively. Among the pulses, chickpea is an important rabi season crop with high acceptability and wider use in nutritional food basket. A field experiment was carried out on medium black calcareous soil at Junagadh Agricultural University, Junagadh, Gujarat during rabi season 2017-18 under saurastra condition to evaluate agronomic biofortification of zinc in chickpea (Cicer arietinum L.) varieties through seed, soil and foliar application. Methods: The experiment was laid out in factorial randomized block design with three replications. The treatment combinations comprised two varieties viz., GG 1 (V 1) and GJG 3 (V 2) and six zinc fortification treatments viz., control, seed treatment ZnSO 4 @ 3 g kg-1 seed, 0.5% ZnSO 4 foliar spray, seed treatment ZnSO 4 @ 3 g kg-1 seed + 0.5% ZnSO 4 foliar spray, soil application ZnSO 4 @ 25 kg ha-1 and soil application ZnSO 4 @ 25 kg ha-1 + 0.5% ZnSO 4 foliar spray. The chickpea was grown with standard package of practices. Result: The results revealed that a significant improvement in 100-seed weight, seed yield, stover yield and biological yield were observed with chickpea variety GJG 3 over GG 1. Significantly higher numbers of pods per plant (45.83) was recorded with variety GG 1. Significantly, chickpea variety GJG 3 was found superior in zinc content and uptake in seed and stover. Under agronomic strategy, zinc fortification through soil application ZnSO 4 @ 25 kg ha-1 + 0.5% ZnSO 4 foliar spray at flowering and pod filling stages significantly improved yield attribute and yield viz., pods per plant (55.17), seed yield (2288 kg ha-1) and stover yield (3553 kg ha-1) and quality parameters viz., protein content in seed (22.89%) and protein yield (523 kg ha-1), zinc content and uptake in seed and stover (45.98 and 37.51 ppm and 104.87 and 133.35 g ha-1 , respectively) over all other zinc biofortification treatments.

Chickpea (Cicer arietinum L.) is extensively grown in areas where soils are deficient in zinc (Zn). To determine the response of chickpea to Zn nutrition and to diagnose Zn status in plant tissue, two glasshouse experiments were conducted using Zn-deficient siliceous sandy soil. In Experiment 1, two genotypes of desi chickpea (Dooen and Tyson) were grown at five Zn levels (0, 0.04, 0.2, 1.0 and 5.0 mg kg 1 of soil). After 4 weeks, no difference in growth and no visible symptoms of Zn deficiency were detected. After 6-8 weeks of growth, chlorosis of younger leaves and stipules occured in the Zn 0 treatment, with shoot dry weight being only 24% of that recorded at the highest Zn level. Root growth increased from 0.52 g/plant when no Zn was applied to 1.04 g/plant in the treatment with 0.2 mg Zn kg 1 of soil; no response to further increase of Zn fertilization occurred. Zinc concentration in the whole shoot increased significantly with increased in Zn application. The critical Zn concentration in the shoot tissue, associated with 90% of maximum growth, was 20 mg kg 1 for both genotypes at flowering stage.

Zinc deficiency is not only the cause of low productivity of crops, but it also results in low zinc content in seeds, which leads to poor dietary zinc intake. To study the effect of zinc foliar application on improving plant yield and seed zinc content for human consumption, chickpea plants were raised in refined sand culture with deficient (0.2 µM) and sufficient (1µM) supply of zinc under glasshouse conditions. Prior to initiation of the reproductive phase, zinc was applied as 0.1% ZnSO 4 foliar spray to both zinc sufficient and deficient plants. The plants exposed to different zinc treatments were studied for pollen and stigma structure and their involvement in fertilization and seed yield. Zinc deficiency induces flower abortion, pollen, and ovule infertility leading to low seed set and ultimately its yield. Foliar application of ZnSO 4 to zinc deficient plants at the time of initiation of flowering partially reverses the adverse effect of zinc deficiency on pollen-stigma morphology, pollen fertility, and greatly enhanced seed yield of plants. Zinc foliar application improved not only the boldness and vigor of seeds in zincdeficient plants, but also the seed zinc content in zinc-deficient seeds as well as the sufficient ones.

Zinc (Zn) deficiency is common in most of the chickpea growing areas of the world and growing Zn-efficient genotypes on Zn-deficient soil is a benign approach of universal interest. Response of 13 chickpea genotypes (10 desi and 3 kabuli) to Zn nutrition was studied in a pot experiment under glasshouse conditions. Plants were grown in a Zn-deficient siliceous sand for 6 weeks and fertilized with 0 (Zn ) and 2.5 mg Zn per kg soil (Zn+). When grown with no added Zn, Zn deficiency symptoms (chlorosis of younger leaves and stipules followed by necrosis of leaf margins) appeared 3-4 weeks after planting and were more apparent in cultivars Tyson, Amethyst and Dooen than Kaniva and T-1587. Zn deficiency reduced shoot growth, but it was less affected in breeding lines T-1587 and CTS 11308 than cultivars Tyson, Dooen, Amethyst and Barwon. Among all genotypes, Tyson produced the lowest root dry weight in Zn-treatment. Zinc efficiency based on shoot dry weight showed marked differences among genotypes; breeding lines CTS-60543, CTS-11308 and T-1587 were 2-fold more Zn-efficient than cultivars Tyson and Dooen. A higher Zn accumulation per plant and higher Zn uptake per g. of root dry weight were recorded in T-1587 and CTS-11308 when compared with Tyson. Root:shoot ratio was increased and proportionally more Zn was transported to the shoot when the soil was deficient. Cultivars that were very sensitive to Zn deficiency tended to have their root:shoot ratio increased by Zn deficiency more than less sensitive cultivars. The insensitive lines T-1587 and CTS-11308 transported more than 70% of the total absorbed Zn to the shoot. It is concluded that chickpea genotypes vary in their sensitivity to Zn deficiency. Advanced breeding lines T-1587 and CTS-11308 are relatively more Zn-efficient compared with Australian chickpea cultivar Tyson. Zn efficiency in chickpea genotypes is probably related to an efficient Zn absorption coupled with a better root to shoot transport.

Zinc (Zn) and Iron (Fe) deficiencies in soil lead to lesser concentration of these micronutrients in seeds and cause physical and mental health problems to human beings. Hence, agronomic bio-fortification of micronutrients is the good remedy for increasing the content of Zn and Fe in a seed. In this experiment two genotypes of chickpea were applied with Zn and Fe through foliage in the form of sulphates at different stages and also tested with the application to soil and via a seed treatment. Genotype GBM-2 recorded higher yield, Zn and Fe content in seed than JG-11. However JG-11 was more efficient in using native Zn and Fe, as it had shown higher Zn and Fe agronomic efficiency under all the methods compared to GBM-2. Foliar application of Zn and Fe proved better method of application compared to soil application or seed treatment of Zn or individual application of Zn or Fe. Yield increase was 20.2 and 19.35% higher in foliar application of Zn and Fe over control respectively in 2016 and 2017. Foliar application of Zn with Fe recorded 22.29 and 11.30% higher Zn accumulation in seed over soil application of micronutrients in 2016 and 2017, respectively.

A field experiment was planned and conducted during Rabi 2015-16 to evaluate the “Studies on use of potassium and zinc on yield and nutrient uptake by chickpea”. The experiment was conducted the Departmental Research Farm of Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out in Randomized Block Design with three replications. There were eight treatments comprising of K and zinc levels viz; T1- Absolute control, T2- Only RDF through soil (25:50:00 NPK kg ha-1), T3 –RDF + 15 kg K2O ha-1, T4- RDF + 30 kg K2O ha-1, T5- RDF+45 kg K2O ha-1, T6- RDF+15 kg K2O ha-1+25 kg ZnSO4 ha-1, T7- RDF + 30 kg K2O ha-1 + 25 kg ZnSO4 ha-1, T8- RDF + 45 kg K2O ha-1 + 25 kg ZnSO4 ha-1. The results indicated that, the application of RDF + 30 kg K2O ha-1 +25 kg ZnSO4 ha-1 improved growth, quality parameters and increased grain and straw yield. Soil fertility status (available N, P, K, and S), micronutrients and plant nutrient concentration were higher in the treatments receiv...

Chickpea cultivation in Brazil has not yet been consolidated, and studies aiming at the adequate nutritional management for this crop are necessary. This work aimed to evaluate the production of chickpea plants (cultivar BRS Aleppo) subjected to fertilization with zinc and P doses. The experimental was completely randomized, with four replications, in a 3 x 5 factorial scheme, corresponding to three fertilization treatments with Zn (without Zn addition; 50% of Zn applied at sowing, via soil + 50% applied at flowering, via leaves; and 100% applied at sowing, via soil) and five doses of phosphorus (0, 60, 120, 180, and 240 kg ha-1 of P2O5). The 100-grain mass (M100), pod mass (MV), number of pods (NV), number of grains (NG), total grain mass (MGT), yield (PROD), dry matter of the shoot part (MSPA) and plant residues (MSRV), and agronomic efficiency (EA) were characterized. There was an isolated effect of the P doses on the M100, MGT, PROD, MSPA, and MSRV characteristics. The applicati...
