Boosting wheat yield, profitability and NUE with prilled and nano urea in conservation tillage.

Rice-wheat production in the Indo-gangetic plains (IGPs) of India faces major concerns such as depleting resources, rice residue burning, excessive fertilizer use, and decreasing nitrogen use efficiency. These issues threaten sustainable crop production in the future. Therefore, a field study was conducted during the winter seasons of 2020-21 and 2021-22 to evaluate the effect of combined conventional and nano fertilizers on nitrogen application just before or after irrigation to improve wheat productivity, profitability and NUE under conservation tillage.

Nitrogen uptake and remobilization from pre- and post-anthesis stages contribute towards grain yield and grain protein concentration in wheat grown in limited nitrogen conditions.

Background: In wheat, nitrogen (N) remobilization from vegetative tissues to developing grains largely depends on genetic and environmental factors. The evaluation of genetic potential of crops under limited resource inputs such as limited N supply would provide an opportunity to identify N-efficient lines with improved N utilisation efficiency and yield potential. We assessed the genetic variation in wheat recombinant inbred lines (RILs) for uptake, partitioning, and remobilization of N towards grain, its association with grain protein concentration (GPC) and grain yield.

Physio-molecular traits of contrasting bread wheat genotypes associated with N influx exhibiting homeolog expression bias in nitrate transporter genes under different external nitrate concentrations.

The high affinity nitrate transport system is a potential target for improving nitrogen use efficiency of bread wheat growing either under optimal or limiting nitrate concentration. Nitrate uptake is one of the most important traits to take into account to improve nitrogen use efficiency in wheat (Triticum aestivum L.).

Sustainable intensification of maize and wheat cropping system through pulse intercropping.

The intercropping of legumes with cereals help to achieve sustainable intensification by their mutual complementarity at efficiently using radiation, nutrients, etc. Several studies indicated such beneficial effects on the other component crop however, little research has been conducted to quantify their effects on the subsequent crop in a cropping system. In this study, the effect of the legume intercropping on the entire cropping system, particularly the maize + legume-wheat system was studied.

Optimization of Agrobacterium-mediated transformation in spring bread wheat using mature and immature embryos.

Wheat is the most widely grown staple food crop in the world and accounts for dietary needs of more than 35% of the human population. Current status of transgenic wheat development is slow all over the world due to the lack of a suitable transformation system. In the present study, an efficient and reproducible Agrobacterium-mediated transformation system in bread wheat (Triticum aestivum L.

Development of an efficient and reproducible regeneration system in wheat ( L.).

The availability of reproducible regeneration system through tissue culture is a major bottleneck in wheat improvement program. The present study has considered to develop an efficient callus induction and regeneration system using mature and immature embryos as explants in recently released agronomically superior spring wheat varieties. An efficient sterilization process was standardized using 0.
