Evaluation of different wheat cultivars under salinity stress

A field experiment was conducted to study the response of different 11 wheat (Triticum aestivum L.) cultivars under saline condition and by applying saline irrigation water during rabi 2016-17 at Krishi Vigyan Kendra, Sri Muktsar Sahib (Punjab). Experiment site was chosen with high salinity condition (EC=1.87 dS/m) to check the response of particular cultivars in these conditions. The field was only irrigated with tube well water having very high EC (4630 micro mhos/cm). Results showed that the grain yield was recorded higher in KH 65 (5648 kg/ha), KRL 210 (5440 kg/ha), KRL 386 (5290 kg/ha) and DBW 246 (5048 kg/ha) as compared to lower grain yield recorded with KRL 384 (4353 kg/ha), KRL 19 (4423 kg/ha), KRL 370 (4538 kg/ha), DBW 248 (4608 kg/ha),WH 1316 (4838 kg/ha), DBW 247 (4860 kg/ha) and KRL 377 (4895 kg/ha). The experimental site was slightly saline in nature, so the cultivar KH 65, KRL 210, KRL 386 and DBW 246 are very suitable for the area as these were less affected due to salinity. Grain yield among these varieties were higher due higher number of effective tiller per unit area and due to large number of grains per ear. Whereas, KH 65, KRL 377 and KRL 386 also produced significantly higher straw yield from WH 1316, DBW 248, DBW 247, KRL 210, KRL 384, DBW 246, KRL 370 and KRL 19

Production potential and economics of wheat, Triticum aestivum as influenced by different planting methods in Punjab, India

The burning of rice straw after rice harvest in the Rice-Wheat System can be overcome by direct seeding of wheat by in standing and loose rice straw. To find out the most appropriate method of wheat sowing after rice crop in Sri Muktsar Sahib district, a field experiment was conducted with five different sowing methods including zero tillage and happy seeder. Among the different planting methods maximum grain yield was obtained with the conventional (52.26 q/ha) and happy seeder without loose straw (51.93 q/ha) planting method as compared to happy seeder with loose straw (50.83 q/ha), zero tillage (49.80 q/ha) and conventional method with mulching (49.66 q/ha). However, the benefit-cost ratio was higher by happy seeder with (2.38:1) and without loose straw (2.35:1) as compared to zero tillage method (2.31:1) and conventional (2.14:1). Higher B:C ratio with happy seeder was also due to its lesser cost of cultivation as compared to conventional method of sowing. The higher net return obtained from happy seeder with and without loose straw Rs. 50104 and Rs. 51019/ha respectively as compared zero tillage method (Rs 48663/ha) and conventional tillage method (Rs. 49856/ha). Although the grain yield under conventional method of sowing was higher but it failed to produce higher net return and B:C ratio. Happy Seeder technology is a time savings, good option against burning of rice residue in Punjab

Field-Induced Single Molecular Magnetism and Photoluminescence in Rare Cocrystals of Isomorphic Lanthanide(III) Coordination Compounds with Fully Substituted Pyridine-4-carboxamide Ligand

International audienceA series of four isomorphous, 1:2 (complex/) rare cocrystals of coordination compounds of Ln(III) ions as [Ln()(NO)(HO)][] (Ln(III) = Gd (), Tb (), Dy (), and Ho ()), were synthesized with ,-diisobutylisonicotinamide () using a metal-to-ligand ratio of 1:1. All compounds are dimeric in nature with two cocrystallized molecules centro-symmetrically interspersed between two dimeric units with H-bonded bridges between them to form interesting, self-assembled H-bonded tapes along the -axis. Detailed Shape analysis and Hirshfeld analysis are done to demonstrate geometry around the metal centers and various noncovalent interactions present in the systems, respectively. Magnetic studies show that compound is a field-induced single-molecule magnet (SMM) for which the magnetization relaxes through a combination of Orbach (Δ = 51 K and τ = 3.1 × 10 s) and Raman mechanisms. Solid-state luminescence studies reveal that compounds , , and are photoluminescent in the visible range, while exhibits luminescence in the NIR region. Compound shows cold white-light emission with Commission Internationale de l'Eclairage (CIE) coordinates (0.31, 0.30) and correlated color temperature (CCT) value of 6942 K

Role Reversal of the Carboxylate Group from Coordination to Hydrogen Bonding Only, in Structurally Diverse Metal-2-amino,5-Nitro-benzoates: A First Report

The remarkable structural diversities arising from a small ligand, 2-amino,5-nitro-benzoic acid <b>(L1H</b>), equipped with different functional groups, conferring tunable coordination sites as well as H-bonding abilities, have been explored. Six new crystal structures of Cs­(I), Na­(I), K­(I), and Li­(I) ions with <b>L1</b> have been realized. Notably, for the medium-sized alkali metal ions, a role reversal between the coordination and H-bonding nature of −COO^– and −NO₂ groups, respectively, has been observed for the first time. Since <b>L1</b> possesses three potential sites for coordination as well as H-bonding interactions, we realized a delicate control of noncovalent interactions on the resulting supramolecular assemblies. Structural diversities observed range from one-dimensional helices and linear threads to two-dimensional brick-wall types or three-dimensional networks. The electrostatic surface potential (ESP) of three representative complexes provided an insight into the electronic-deficient and electron-rich regions. The coordination of Na­(I) and K­(I) ions through the nitro groups extends the electron-deficient region of the complexes. The electron densities at the bond critical paths of the representative complexes were calculated to understand the supramolecular outcome of the coordination polymers. Unravelling of such critical electronic information is paramount toward the systematic construction of a new generation of complex coordination polymers

Post-combustion CO2 capture of methyl and nitro mixed-linker CAU-10

Methyl- and nitro-group-co-functionalized CAU-10, namely CAU-10-CH3-NO2, was synthesized and compared with mono-functionalized CAU-10 derivatives, CAU-10-CH3 and CAU-10-NO2, as a CO2 adsorbent. In this study, we report that methyl and/or nitro groups could increase CO2 performance compared to that of bare CAU-10. It is supposed that the hydrophobic character of the methyl group might support selective CO2 uptake in humid conditions. Breakthrough experiments demonstrate that CAU-10-CH3-NO2, which is more hydrophobic than CAU-10-NO2, reduced the degradation of adsorption performance under dry conditions. CAU-10-CH3-NO2 was considered a candidate suitable for an actual post-combustion CO2 adsorption process.
