Nitrogen (N) fertilizer is commonly applied to wheat crops (Triticum aestivum L.) during the vegetative growth to meet crop requirements. Current decision rules for N application result in N losses to the environment, and thus to low N use efficiency, due to excess of N fertilizer and/or poor synchrony between soil supply and crop N demand. Despite existing tools and methods to manage N fertilization

We evaluated nematicidal potential of chitosan in combination with chopped leaves of Argemone mexicana L., Achyranthes aspera L., and Ricinus communis L. against infestation caused by M. incognita on carrot under both in vitro and in vivo.

Can calcium and boron leaf application increase soybean yield and seed quality? Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2021-02-17 Cleyton da Silva Domingos; Marcos Renan Besen; Michel Esper Neto; Eunápio José Oliveira Costa; Carlos Alberto Scapim; Tadeu Takeyoshi Inoue; Marcelo Augusto Batista; Alessandro Lucca Braccini
ABSTRACT Nutrient leaf application is complementary to soybean nutritional management, mainly at maturity, when plants present high nutritional demand and high nutrients and photoassimilate translocation rates for seed production. The aim of this research was to evaluate the agronomic performance, physiological quality, and nutritional contents of soybean seeds after application of different rates

Classification of pest detection in paddy crop based on transfer learning approach Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2021-02-17 V. Malathi; M. P. Gopinath
ABSTRACT Pest recognition in the agriculture field plays a critical issue for the farmers which diminishes economic growth. So far, traditional practices were followed by farmers to increase yield production. Nowadays, researchers execute a deep learning approach to classify various kinds of images practically. In this paper, Deep convolutional neural networks (DCNN) are used to recognise ten kinds

Performance of novel sorghum germplasm in Pennsylvania and their response to anthracnose (Colletotrichum sublineola) Crop Sci. (IF 1.878) Pub Date : 2021-02-16 Iffa Gaffoor; Germán V. Sandoya; Katia V. Xavier; Etta M. Nuckles; Srinivasa R. Pinnamaneni; Lisa J. Vaillancourt; Surinder Chopra
Sorghum (Sorghum bicolor L.) has the potential to become a widespread commercial feedstock crop in Pennsylvania, either in rotation with maize (Zea mays L.), or grown alongside it. In other locations where sorghum has been grown for a long time, it is attacked by Colletotrichum sublineola Henn. ex Sacc. & Trotter, a fungal pathogen that causes anthracnose leaf blight (ALB), thereby diminishing yield

Phytochemical Compounds and Antioxidant Activity of the Pulp of Two Brazilian Passion Fruit Species: Passiflora Cincinnata Mast. And Passiflora Edulis Sims Int. J. Fruit Sci. (IF 0.877) Pub Date : 2021-02-14 T. Barbosa Santos; F. P. de Araujo; A. F. Neto; S. T. de Freitas; J. de Souza Araújo; S. B. de Oliveira Vilar; A. J. Brito Araújo; M. S. Lima
ABSTRACT About 600 species of Passiflora are described around the world, of which 120 are native to Brazil. In the present work, the phytochemical compounds were analyzed by high-performance liquid chromatography, and the antioxidant activities (AOX) were measured in the pulp of P. edulis and P. cincinnata species. The P. edulis presented a higher bioactive content and AOX when compared to P. cincinnata

Effects of Phytophthora sojae inoculation under flooded conditions on growth of soybean seedlings Plant Prod. Sci. (IF 1.696) Pub Date : 2021-02-12 Terufumi Tada; Momo Kato; Chihiro Tanaka; Tatsuhiko Shiraiwa
ABSTRACT Phytophthora root and stem rot due to Phytophthora sojae is a major constraint of soybean production. This study evaluated the combined effect of P. sojae inoculation and flooding on growth of soybean seedlings. The soybean cultivar ‘Enrei’ was grown in a greenhouse in pots containing vermiculite and containers of field soil. The plants were inoculated with two P. sojae isolates and subjected

Assessment of genetic diversity and agronomic traits of durum wheat germplasm under drought environment of the northern Great Plains Crop Sci. (IF 1.878) Pub Date : 2021-01-06 Evan Salsman; Yuan Liu; Seyed Ali Hosseinirad; Ajay Kumar; Frank Manthey; Elias Elias; Xuehui Li
Durum wheat (Triticum turgidum L. ssp. durum) is an important food crop worldwide. Modern breeding has yielded elite durum wheat cultivars with improved grain yield, end‐use quality, and disease resistance. In this study, we compared 150 breeding lines from the North Dakota State University (NDSU) durum wheat breeding program to 163 durum landraces using a large set of single nucleotide polymorphism

Influence of brush type and brushing frequency on putting green ball roll distance and turfgrass quality Crop Sci. (IF 1.878) Pub Date : 2021-02-15 Timothy T. Lulis; Travis R. Russell; John E. Kaminski
Golf course managers manipulate cultural practices in preparation for golf tournaments to increase ball roll distance (BRD) for short periods of time. Brushing putting greens, thought to be a relatively minimally disruptive cultural practice using brush attachments mounted to mower units to vertically orient leaf blades prior to mowing, is growing in popularity despite little research validating purported

Rapid generation cycling transforms pyrethrum (Chrysanthemum cinerariifolium) into an annualized perennial Crop Sci. (IF 1.878) Pub Date : 2021-01-12 Neil O. Anderson; Robert A. Suranyi; Steven M. Gullickson
Pyrethrum [Chrysanthemum cinerariifolium (Trevir.) Vis.] is an important “green pesticide” crop widely used for insect control on plants and for humans. Pyrethrum flowers have the highest Pyrethrin I/Pyrethrin II ratio (%Py) and are harvested at specific stages to maximize yield. Selection for correlative early seed germination and flowering in first year pyrethrum seedlings is challenging and has

Growth response of alfalfa to Azomite composite micronutrient fertilizer on four lime‐amended Virginia soils Grassl. Sci. (IF 0.867) Pub Date : 2021-02-15 Nana Yaw O. Kusi; Vitalis W. Temu; Maru K. Kering; Asmare Atalay; Laban K. Rutto; Juan K. Q. Solomon
The growth responses of alfalfa (Medicago sativa L.) to azomite, a natural composite earth mineral, were assessed in a greenhouse experiment at Virginia State University, Chesterfield, VA. Alfalfa plants were raised on lime‐amended Bojac, Bourne, Emporia and Cullen soils that received 224 kg K/ha in 14 × 16 cm pots. Azomite, a natural composite micronutrients fertilizer, was applied at 0, 200, 400

Variations in ion transportation and accumulation in alfalfa plants under NaCl and Na2HCO3 stresses with different pH levels Grassl. Sci. (IF 0.867) Pub Date : 2021-02-13 Xiaoshan Wang; Longyang Liu; Bingsheng Wang; Qiyue Dingxuan; Guisheng Zhou
For revealing the effects of NaCl and NaHCO3 stress at different pH levels on the absorption and accumulation of main ions in roots, stems and leaves, alfalfa (Medicago sativa L.) plants were cultivated in a nutrient solution system. After NaCl and Na2HCO3 imposition, the contents of main ions in roots, stems, leaves and xylem bleeding sap were determined. Under NaCl and Na2HCO3 stresses with the same
