Post-rainy sorghum (Sorghum bicolor (L.) Moench) production underpins the livelihood of millions in semiarid tropics, where crop is affected by drought. Drought scenarios have been classified and quantified using simulation. In this report, variation traits that hypothetically contribute to drought adaptation (plant growth dynamics, canopy root water conducting capacity, stress responses) were virtually introgressed into most common post-rainy genotype, influence these on plant growth,...
The reproductive phase of chickpea (Cicer arietinum L.) is more sensitive to water deficits than the vegetative phase. characteristics that confer drought tolerance genotypes at stage are not well understood; especially which responsible for differences in seed yield under stress. In two consecutive years, 10 with contrasting yields terminal stress field were exposed a gradual, but similar, glasshouse. Flower number, flower + pod abortion percentage, weight, yield, 100-seed weight (seed...
Terminal drought stress leads to substantial annual yield losses in chickpea (Cicer arietinum L.). Adaptation water limitation is a matter of matching supply demand by the crop. Therefore, harnessing genetics traits contributing plant use, i.e. transpiration rate and canopy development dynamics, important design crop ideotypes suited varying range limited environments. With an aim identifying genomic regions for vigour (growth size) conductance traits, 232 recombinant inbred lines derived...
Traits influencing plant water use eventually define the fitness of genotypes for specific rainfall environments. We assessed response several traits to vapour pressure deficit (VPD) in pearl millet (Pennisetum glaucum (L.) R.Br.) known differ drought adaptation mechanisms: PRLT 2/89–33 (terminal drought-adapted parent), H 77/833–2 drought-sensitive parent) and four near-isogenic lines introgressed with a terminal tolerance quantitative trait locus (QTL) from (ICMR01029, ICMR01031,...
Sorghum contributes to the livelihoods of millions food-insecure households in semi-arid agri-systems. Annual production widely fluctuates throughout India due erratic rainfall and suboptimal agronomic practices. Our novel approach utilizes digital reflection post-rainy (rabi) sorghum systems help better understand its spatio-temporal variations enable designing geography-specific, climate-responsive system interventions (Genotype × Management; GxM). For this, we evaluated a range...
The Unmanned aerial vehicles (UAVs) - based imaging is being intensively explored for precise crop evaluation. Various optical sensors, such as RGB, multi-spectral, and hyper-spectral cameras, can be used this purpose. Consistent image quality crucial accurate plant trait prediction (i.e., phenotyping). However, achieving consistent pose a challenge qualities affected by i) UAV camera technical settings, ii) environment, iii) field characters which are not always under the direct control of...
Non-invasive crop analysis through image-based methods holds great promise for applications in plant research, yet accurate and robust trait inference from images remains a critical challenge. Our study investigates the potential of AI model ensembling hybridization approaches to infer sorghum traits RGB generated via unmanned aerial vehicle (UAV). In our study, we cultivated 21 cultivars two independent seasons (2021 2022) with gradient fertilizer water inputs. We collected 470 ground-truth...
In India, raw peanuts are obtained by aggregators from smallholder farms in the form of whole pods and price is based on a manual estimation basic peanut pod kernel characteristics. These methods produce evaluation slow can result procurement irregularities. The delays combined with lack storage facilities lead to fungal contaminations pose serious threat food safety many regions. To address this gap, we investigated whether X-ray technology could be used for rapid assessment key qualities...
Terminal drought causes major yield loss in chickpea, so it is imperative to identify genotypes with best suited adaptive traits secure terminal drought-prone environments. Here, we evaluated chickpea (At) rd29A:: DREB1A transgenic events (RD2, RD7, RD9 and RD10) their untransformed C235 genotype for growth, water use under water-stress (WS) well-watered (WW) conditions. The assessment was made across three lysimetric trials conducted contained environments the greenhouse (2009GH 2010GH)...
Sorghum plays an important role in the mixed crop–livestock system of tribal farming communities Adilabad District, a high climate risk-prone region India. Currently, local seed is limited to landraces and hybrids that are primarily used for domestic grain fodder purposes. This study aimed understand farmers' needs context, use this knowledge deliver relevant, adoptable climate-smart sorghum crop technologies through farmer-participatory approaches (FPAs). We conducted ex-ante survey with...
This study was primarily triggered by the requirements of crop breeding programs to rapidly, accurately and cost-effectively select genotypes with enhanced biomass Nitrogen (N) content (an essential indicator stover quality as feed) and, at same time, possibly speed up agriculture transition more sustainable precise application fertilizers (crop health status). proof concept explores whether how precisely it is possible predict N in sorghum using a minimum unmanned aerial vehicle...
Pearl millet is an important staple food for farming communities across semi-arid tropical systems of South Asia and Sub-Saharan Africa where production suffers uncertain precipitation. This work undertaken under the premise that maximizing grain yield water-limited conditions depends on both maximizing water use and ensuring availability for grain filling period. Here we discuss phenotyping methods targeting variability in plant strategies which determine crop success...
