Flowering responses of serradella (Ornithopus spp.) and subterranean clover (Trifolium subterraneum L.) to vernalisation and photoperiod and their role in maturity type determination and flowering date stability Crop Pasture Sci. (IF 1.9) Pub Date : 2023-04-06 Laura E. Goward, Rebecca E. Haling, Rowan W. Smith, Beth Penrose, Richard J. Simpson
Context: Serradellas (Ornithopus spp.) are promising alternative annual legumes to subterranean clover (Trifolium subterraneum L.), for permanent, temperate pastures. However, many cultivars exhibit unstable flowering dates across years. This is a risk for seed production and persistence. Aim: This study assessed how vernalisation and photoperiod cues determine maturity type and flowering date stability

Phosphorus responses of Trifolium pallescens and T. occidentale, the progenitors of white clover (T. repens) Crop Pasture Sci. (IF 1.9) Pub Date : 2023-04-04 Shirley N. Nichols, James R. Crush, Vanessa M. Cave, Warren M. Williams
Context: Rock phosphate reserves are decreasing, and requirements to mitigate environmental impacts of farming soils with excess phosphorus (P) are increasing. Aims: White clover is an allotetraploid hybrid between Trifolium pallescens and T. occidentale. Understanding the P response characteristics of these progenitor species will allow selection of germplasm for development of synthetic white clovers

Overexpression of rice acyl-CoA-binding protein OsACBP5 protects Brassica napus against seedling infection by fungal phytopathogens Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-31 Saritha Panthapulakkal Narayanan, Aruni Y. Alahakoon, Candace E. Elliott, Derek Russell, Paul W. J. Taylor, Clive Lo, Mee-Len Chye
Context: Class III acyl-CoA-binding proteins such as those from dicots (Arabidopsis and grapevine) play a role in defence against biotrophic pathogens. The overexpression of the monocot Oryza sativa (rice) OsACBP5 in Arabidopsis and rice has been demonstrated to enhance broad-spectrum disease resistance against selected phytopathogens in OsACBP5-overexpressing (OsACBP5-OE) lines. Aims: We aimed to

Digital agriculture in Europe and in France: which organisations can boost adoption levels? Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-28 Véronique Bellon-Maurel, Isabelle Piot-Lepetit, Nina Lachia, Bruno Tisseyre
This paper presents the way the digital transformation of the agricultural sector is implemented in Europe and in France. It describes the main European and national strategies, the structure of research and innovation initiatives, and the investment in capacity building to foster innovation, adoption and use. More specifically, the French research and innovation ecosystem on digital agriculture is

Light competition is the key factor determining spatio-temporal variability in legume proportion within Marandu palisadegrass–forage peanut mixed pastures Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-21 Paola Palauro Spasiani, Bruno Grossi Costa Homem, Italo Braz Gonçalves de Lima, Bianca Costa Guimarães, Elias Silva de Medeiros, James Pierre Muir, Marcelo Silva de Oliveira, Robert Michael Boddey, Daniel Rume Casagrande
Context: Understanding ecology in grass–legume pastures can help support strategies aimed at maintaining canopy stability in terms of botanical composition. Aims: This 2-year study evaluated spatial variability, focusing on plant structural characteristics in a Marandu palisadegrass [Urochloa brizantha (Hochst. Ex A. Rich.) R.D. Webster cv. Marandu]–forage peanut (Arachis pintoi Krapov. and W.C. Greg

Siphoning novel sources of seedling salinity tolerance from the diverse chickpea landraces Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-14 Nilesh Joshi, Sneha Priya Pappula Reddy, Neeraj Kumar, Chellapilla Bharadwaj, Kumar Tapan, B. S. Patil, Pradeep Kumar Jain, Nimmy M. S., Manish Roorkiwal, Preeti Verma, Rajeev K. Varshney, Kadambot H. Siddique, Sudhir K.
Context: Chickpea (Cicer arietinum L.) are highly sensitive to elevated salinity, particularly at initial seedling establishment stage. Seedling screening would be an effective means to identify novel sources of donors for salt tolerance. Aim: This study aimed to identify salt stress tolerant genotypes at seedling stage from 50 chickpea accessions. Methods: The screening of 50 chickpea accessions was

Development of low-phytate maize inbred lines through marker-assisted introgression of lpa1 Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-14 K. R. Yathish, Chikkappa G. Karjagi, Shivraj S. Gangoliya, Raveendra N. Gadag, M. G. Mallikarjuna, Javaji C. Sekhar, Abhijit K. Das, P. Lakshmi Soujanya, Ramesh Kumar, Alla Singh, Shyam Bir Singh, Sujay Rakshit
Context: Phytic acid is the major storage form of phosphorus in cereals and is considered an anti-nutritional factor because it chelates major mineral micronutrient cations, resulting in micronutrient malnutrition in humans. For monogastric animals fed maize (Zea mays L.) grains, the stored phosphorus does not release into the digestive tract, leading to phosphorus deficiency and environmental pollution

Tillage, crop establishment and residue retention methods for optimising productivity and profitability under rice–wheat system Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-08 H. S. Thind, Sandeep Sharma, H. S. Sidhu, Vicky Singh, Yadvinder-Singh
Conventional tillage and crop establishment methods for the rice–wheat (RW) system are input intensive (water, labour and energy). About 24.5 million tonnes of rice residues are burnt every year on farms in north-western India before sowing of wheat, causing air pollution and soil health degradation. Therefore, alternative tillage, crop establishment and residue management practices are needed for

Vernalisation and photoperiod responses of diverse wheat genotypes Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-08 Maxwell T. Bloomfield, Corinne Celestina, James R. Hunt, Neil Huth, Bangyou Zheng, Hamish Brown, Zhigan Zhao, Enli Wang, Katia Stefanova, Jessica Hyles, Tina Rathjen, Ben Trevaskis
Context: Wheat (Triticum aestivum L.) adaptation is highly dependent on crop lifecycle duration, particularly the time at which flowering occurs in a specific environment. Frost, low solar radiation, heat and drought can significantly reduce yield if a crop flowers too early or late. Wheat genotypes have different lifecycle durations determined by plant responses to temperature (thermal time accumulation

Whither digital agriculture in India? Crop Pasture Sci. (IF 1.9) Pub Date : 2023-03-08 Rupak Goswami, Sudarshan Dutta, Sanchayeeta Misra, Shubhadip Dasgupta, Somsubhra Chakraborty, Kousik Mallick, Aditya Sinha, Vinod K. Singh, Thomas Oberthür, Simon Cook, Kaushik Majumdar
Agriculture is central to the Indian economy and suffers from widespread operational inefficiencies that could be corrected by the use of digital agriculture technologies (DA). We review and synthesise available literature concerning digital agriculture in India and anticipate its transformative potential in the coming decade. Although the initial growth of DA was more conspicuous in the downstream
