Effect of Lolium perenne population differences on shoot tissue nitrogen concentrations when grown on a peat soil J. Agric. Sci. (IF 2.0) Pub Date : 2023-08-24 Jeroen Pijlman, Nyncke Hoekstra, Joachim Deru, Jan Willem Erisman, Nick van Eekeren
Grass nitrogen (N) concentrations of dairy grasslands are higher on peat soil than on mineral soils. This can lead to increased N losses to air and water from dairy farming systems on peat soils. Our hypothesis was that the use of low-N perennial ryegrass (Lolium perenne L.) genotypes could be a means to lower grass N concentrations, when grown on peat soils. Our objective was to determine whether

Effect of pre-grazing herbage mass and post-grazing sward height on herbage production and intake and performance of suckler-bred steers within a weanling-to-beef production system J. Agric. Sci. (IF 2.0) Pub Date : 2023-03-24 P. R. Doyle, M. McGee, A. P. Moloney, A. K. Kelly, E. G. O'Riordan
The current study investigated the effects of pre-grazing herbage mass (PGHM, 1500 or 2500 kg dry matter (DM)/ha) and post-grazing sward height (PGSH, 4 or 6 cm) on herbage production and its nutritive value and DM intake, grazing behaviour and growth of Charolais steers (n = 96; 12 months of age; 396 ± 19.0 kg) during a 222-day grazing season, and the subsequent effect of an indoor finishing diet

Assessment of crop water stress index and net benefit for surface- and subsurface-drip irrigated bell pepper to various deficit irrigation strategies J. Agric. Sci. (IF 2.0) Pub Date : 2023-03-23 Y. Bozkurt Çolak, A. Yazar, M. Yıldız, S. Tekin, E. Gönen, A. Alghawry
This study addresses the assessment of crop water stress index (CWSI) of bell pepper (Capsicum annuum L.) and net income generated under regulated deficit irrigation (RDI), conventional deficit irrigation and partial root-zone drying (PRD) and full irrigation (I100) using surface- and subsurface-drip systems (DI and SDI) during 2016 and 2017 in the Mediterranean region. The experimental design was

Soybean seed protein concentration is limited by nitrogen supply in tropical and subtropical environments in Brazil J. Agric. Sci. (IF 2.0) Pub Date : 2023-03-02 E. H. Figueiredo Moura da Silva, N. Cafaro La Menza, G. G. Munareto, A. J. Zanon, K. Santos Carvalho, F. R. Marin
Soybean production contributes to ca. 60% of global plant-based protein used for food and feed. Brazil is the largest soybean producer and exporter, with 60% from tropical and 40% from subtropical environments. Nitrogen (N) can play an essential role in the storage of proteins in seeds; thus, it could be a key factor in increasing the quantity and quality of seeds in high-yielding soybean crops. Unlike

Identification of weak links in production technology for bridging the canola yield-gap in Punjab, Pakistan J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-22 Shakeel Ahmad, Muhammad Ali Raza, Sajjad Hussain, Ghulam Abbas, Zartash Fatima, Mukhtar Ahmed, Muhammad Arif Goheer, Carol Jo Wilkerson, Axel Garcia y Garcia, Gerrit Hoogenboom
Understanding the reasons for the yield gap between potential and actual yield can provide insights for enhancing canola production by adapting measures for ensuring food security. The canola yield gap under different management practices (e.g. water, nitrogen, N- and sowing dates) was quantified using research trials that were conducted at on-station and historical data (1980–2016) and the CROPGRO-Canola

Photosynthesis rate, radiation and water use efficiencies of irrigated potato in a semi-arid climate using Eddy covariance techniques J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-22 A. T. B. Machakaire, J. M. Steyn, A. C. Franke
Understanding the photosynthetic behaviour, radiation use efficiency (RUE) and water use efficiency (WUE) of potatoes in response to diurnal and seasonal fluctuations in weather, is important for optimizing growth and production. The net ecosystem exchange (NEE) of carbon dioxide (CO2), is a parameter used to measure the balance between gross CO2 assimilation (also referred to as gross primary production

Can a urease inhibitor improve the efficacy of nitrogen use under perennial ryegrass temperate grazing conditions? J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-21 Á. Murray, T. J. Gilliland, L. Delaby, D. Patton, P. Creighton, P. J. Forrestal, B. McCarthy
This study sought to compare the efficiency of different nitrogen (N) fertilizer forms applied to perennial ryegrass swards that were rotationally grazed by dairy cows or sheep under Irish conditions for two or three years. A 3 × 2 factorial random complete block design plot arrangement was used to compare calcium ammonium nitrate (CAN), urea and urea + N-(n-butyl) thiophosphoric triamide (urea + NBPT)

Effect of three crop rotations and four residue levels on canola and bean grain yield and residue production J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-17 Juan Hirzel, Pablo Undurraga, Lorenzo León, Iván Matus
Crop rotation in agriculture can lead to increased crop productivity in the rotation and improved soil fertility as a result of residue incorporation. Unfortunately, residue incorporation is not a common practice in crop production systems under the Mediterranean regime, largely due to the lack of information on the effect of the follow-up crops. Therefore, this study was conducted with six biannual

Evaluating the effects of defoliant spraying time on fibre yield and quality of different cotton cultivars J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-17 Liyuan Wang, Yongsheng Deng, Fanjin Kong, Bing Duan, Muhammad Saeed, Ming Xin, Xiaoge Wang, Liying Gao, Guifang Shen, Jinghui Wang, Zongfu Han, Zongwen Wang, Xianliang Song
Chemical defoliants are widely used in cotton (Gossypium L.) to accelerate leaf abscission and boll maturation, as well as, to facilitate mechanical harvesting. The current study was conducted to determine the interactive effect of cotton cultivars and spraying time of defoliant on defoliation, boll opening, fibre yield and quality. An experiment was performed with four cultivars and three defoliant

Spatial and temporal dynamics of cropland in the Sanjiang Plain from 2014 to 2020 based on annual 30 m crop data layers J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-16 Cui Jin, Zeyu Zhang, Hongyan Cai, Ge Cao, Xintao Li, Xueming Li
The land cover of the Sanjiang Plain has changed dramatically since the 1950s. Although previous studies have analysed its spatiotemporal dynamics at long time intervals, a near real-time and accurate representation of the interannual evolution of cropping patterns in this region is of far-reaching importance for rationally allocating agricultural resources and ensuring food security. Based on the

Soil quality assessment based on hybrid computational approach with spatial multi-criteria analysis and geographical information system for sustainable tea cultivation J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-16 F. Saygın, Y. Şavşatlı, O. Dengiz, K. Yazıcı, A. Namlı, A. Karataş, N. D. Şenol, M. O. Akça, S. Pacci, B. Karapıçak, A. Ay, S. Demirkaya
Long-term intensive tea cultivation is suspected of deteriorating soil quality status and degrading land sustainability. This study aimed to determine the soil quality index of soils in a micro-catchment in Rize Province, Turkey, used for long-term intensive tea cultivation, by means of spatial multi-criteria analysis (SMCA) and standard scoring function (SSF) integrated with geographical information

An innovative technique for faecal score classification based on RGB images and artificial intelligence algorithms J. Agric. Sci. (IF 2.0) Pub Date : 2023-02-15 L. Ortenzi, S. Violino, C. Costa, S. Figorilli, S. Vasta, F. Tocci, L. Moscovini, L. Basiricò, C. Evangelista, F. Pallottino, U. Bernabucci
The milk production is strongly influenced by the dairy cow welfare related to a good nutrition and the analysis of the digestibility of feeds allows us to evaluate the health status of the animals. Through faeces’ visual examination it is possible to estimate the quality of diet fed in terms of lacking in fibre or too high in non-structural carbohydrates. The study was carried out in 2021, on four
