Nanotechnology: boosting rice germination and growth

(0)
March 2, 2021

Germination capacity and seedling growth of basmati rice tend reduce with age. Shadma Afzal and Nand K Singh from NIT Allahabad show how easy it is to surmount the problem by priming seeds with iron nanoparticles.

Priming Rice Seeds for Productivity

Researchers from IIT Kharagpur delved into bacterial endophytes that help improve the health, growth and productivity of rice. They have come up with nine species from four bacterial genera for priming rice seeds to improve productivity.

Gamma Irradiation to Enhance Jasmine Fragrance

Breeding better varieties using conventional seed selection is not possible in jasmine, propagated vegitatively. So researchers in IIT Kharagpur used gamma irradiation on jasmine cuttings to induce mutations that enhance the fragrance of jasmine. Read on for details.

Priming Seeds to Reduce Arsenic Toxicity

Priming seeds with 2-oxoglutarate, a intermediate between carbohydrate and protein metabolic pathways, alleviate the symptoms of arsenic toxicity and reduces accumulation of arsenic in plants. Researchers from Allahabad provide evidence.

Onion Production: Bacteria at the roots

Onion roots don’t stretch too far and for optimum use of surrounding soil fertility, depend on help from soil microbes. Researchers from the Punjab Agricultural University show that a consortium of such bacteria can reduce fertiliser use and increase production.

Transportation Stress in Goats: jaggery and vitamin C to rescue

When transporting goats in vehicles to markets or to abattoirs, they undergo severe stress. Vitamin C and jaggery can help maintain the quality of goats at such times, say researchers from NDRI, Karnal and SKUAST-Kashmir.

Salinity Tolerant Pearl Millet: Role of MicroRNA

Pearl millet is more tolerant to soil salinity than most other crops. Scientists from ICRISAT Hyderabad along with researchers from other parts of the world have now started uncovering the secrets of the success of survival of the crop under salinity. One more step towards sustainable agriculture under the threat of increasing soil salinity.

Stress tolerant crops: genes generate increased yield

Drought, salinity and heat reduce crop yield. Is there a way to make crops tolerant to these abiotic stresses? Neelam Mishra from St. Joseph’s College, Bengaluru explores in collaboration with colleagues from the US and China.

Tilapia Lake Virus: risk to rohu?

Tilapia lake virus is a RNA virus. RNA viruses are famous for evolving and switching hosts. So is co-culturing tilapia and rohu safe for aquaculture industry? Scientists from the ICAR-National Bureau of Fish Genetic Resources, Lucknow, inquire…

Pesticide that doesn’t leave residue on cardamom

Cardamom exports from India have suffered from rejection due to presence of fertilisers. Stanley Johnson and a team from the Tamil Nadu Agricultural University, Coimbatore has a suggestion to save cardamom from insect pests without leaving pesticide residues on the product.
