Grape Cold Hardiness Prediction via Multi-Task Learning [PDF]

arXiv, 2022
Cold temperatures during fall and spring have the potential to cause frost damage to grapevines and other fruit plants, which can significantly decrease harvest yields. To help prevent these losses, farmers deploy expensive frost mitigation measures such as sprinklers, heaters, and wind machines when they judge that damage may occur.

Risk-averse Stochastic Optimization for Farm Management Practices and Cultivar Selection Under Uncertainty [PDF]

arXiv, 2022
Optimizing management practices and selecting the best cultivar for planting play a significant role in increasing agricultural food production and decreasing environmental footprint. In this study, we develop optimization frameworks under uncertainty using conditional value-at-risk in the stochastic programming objective function.

Multi-Task Learning for Budbreak Prediction [PDF]

arXiv, 2023
Grapevine budbreak is a key phenological stage of seasonal development, which serves as a signal for the onset of active growth. This is also when grape plants are most vulnerable to damage from freezing temperatures. Hence, it is important for winegrowers to anticipate the day of budbreak occurrence to protect their vineyards from late spring frost ...

Persistent Homology to Study Cold Hardiness of Grape Cultivars [PDF]

arXiv, 2023
Persistent homology is a branch of computational algebraic topology that studies shapes and extracts features over multiple scales. In this paper, we present an unsupervised approach that uses persistent homology to study divergent behavior in agricultural point cloud data.

Chilling requirement of Ribes cultivars [PDF]

Frontiers in Plant Science, 2015
It is usually thought that adequate winter chill is required for the full flowering of many temperate woody species. This paper investigates the sensitivity of blackcurrant bud burst and flowering to natural weather fluctuations in a temperate maritime climate, and compares a range of chill models that have been proposed for assessing the accumulation ...

Aphid acceptance of Hordeum genotypes is affected by plant volatile exposure and is correlated with aphid growth [PDF]

, 2009
Nineteen genotypes of Hordeum vulgare were characterized as partially resistant or susceptible regarding growth of the bird cherry - oat aphid (Rhopalosiphum padi L.).

BRS 374 - wheat cultivar [PDF]

Crop Breeding and Applied Biotechnology, 2013
BRS 374 is a wheat cultivar developed by Embrapa. It resulted from a cross between the F1 generation of PF 88618/Coker80.33 and Frontana/Karl. BRS 374 belongs to the soft wheat class, has a low plant height, a high potential grain yield, andwhite flour.

Leaf Cultivar Identification via Prototype-enhanced Learning [PDF]

arXiv, 2023
Plant leaf identification is crucial for biodiversity protection and conservation and has gradually attracted the attention of academia in recent years. Due to the high similarity among different varieties, leaf cultivar recognition is also considered to be an ultra-fine-grained visual classification (UFGVC) task, which is facing a huge challenge.

BRS Progresso - Rye cultivar [PDF]

Crop Breeding and Applied Biotechnology, 2014
The rye cultivar BRS Progresso, developed by the Brazilian Agricultural Research Corporation (Embrapa), is the result of a synthetic cross of 18 open-pollinated, self-incompatible lines, resistant to stem rust.

Design and Evaluation of a Modular Robotic Plum Harvesting System Utilising Soft Components [PDF]

Journal of Field Robotics. 2021. 38: 28--306, 2020
The human labour required for tree crop harvesting is a major cost component in fruit production and is increasing. To address this, many existing research works have sought to demonstrate commercially viable robotic harvesting for tree crops, though successful commercial products resulting from these have been few and far between.
