Nitrogen And Sulfur Fertilizers Effects On Growth And Yield Of Brassica Carinata In South Dakota, Dwarika Bhattarai, Sandeep Kumar, Thandiwe Nleya

Agronomy, Horticulture and Plant Science Faculty Publications

Carinata (Brassica carinata A. Braun), a non-food oilseed and an alternative biofuel feedstock, has received attention for its potential as a low-input option for production in the semi-arid regions of the Northern Great Plains (NGP). This study was conducted to (a) determine the economic optimum N and S fertilization rates and (b) determine the interactive effects of N and S fertilization on seed yield and agronomic traits in carinata. The field experiment conducted in 2017 and 2018 at Brookings, SD, had four N rates (56, 84, 112, and 140 kg N ha⁻¹) and three S rates (0, …

Wayne E. Sabbe Arkansas Soil Fertility Studies 2020, Nathan A. Slaton

Arkansas Agricultural Experiment Station Research Series

Rapid technological changes in crop management and production require that the research efforts be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies described within will allow producers to compare their practices with the university’s research efforts. Additionally, soil-test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas.

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr, Meredith M. Guthrie

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Cultivating Hops For Cone Production In Nebraska, Stacy A. Adams

Department of Agronomy and Horticulture: Faculty Publications

The hop cone is the primary product of agronomic value when growing Humulus lupulus L. (common hop). Cones are modified stem and leaf structures that protect the female flower cluster that forms chemical compounds important for flavoring beer and other uses. The majority of hops in the United States (~96%) is grown in the states of Washington, Oregon, and Idaho. Hops can be grown in very diverse climates, but it is the climatic consistency of the Pacific NW that provides product consistency and reasoning commercial hops production is prevalent in the region. Hops is a niche crop outside of the …

On-Farm Assessment Of Cassava Root Yield Response To Tillage, Plant Density, Weed Control And Fertilizer Application In Southwestern Nigeria, Olabisi Omolara Onasanya, Stefan Hauser, Magdalena Necpalova, Felix Kolawole Salako, Christine Kreye, Meklit Tariku, Johan Six, Pieter Pypers

All Peer-Reviewed Publications

Cassava is growing in importance in Nigeria as a food and industrial crop. Current yields are low due to poor soil fertility and because farmers do not use improved germplasm, clean planting material, or improved crop management in Nigeria. To provide feasible agronomic recommendations targeting increased root yield, the effects of tillage intensity, fertilizer application, plant density and weed control were tested in 230 farmers’ fields in southwestern Nigeria over two years. In 2016, tillage treatments were zero, single and double passage with a disc plough, followed by ridging (soil shaping) versus leaving the soil flat. Fertilizer application at 75:20:90 …

A Recalibrated And Tested Lintul-Cassava Simulation Model Provides Insight Into The High Yield Potential Of Cassava Under Rainfed Conditions, J. G. Adiele, A. G.T. Schut, R. P.M. Van Den Beuken, K. S. Ezui, P. Pypers, A. O. Ano, C. N. Egesi, K. E. Giller

All Peer-Reviewed Publications

Accurate assessments of the yield potential of cassava are needed to analyse yield gaps, define yield targets and set benchmarks for actual yields in Nigeria. This study evaluated the crop model LINTUL-Cassava under assumed potential growth and water-limited conditions in Nigeria. On-farm experiments were conducted at six locations across the three major cassava growing agro-ecologies of Western Africa (Tropical Rainforest – Ogoja and Ikom in Cross River state, Rainforest Transition Savanna – Ekpoma in Edo state and Guinea Savanna – Otukpo in Benue state) during two subsequent seasons (2016 – 2018). Treatments included fertilizer rates calculated to support the assumed …

Improved Storage Mitigates Vulnerability To Food-Supply Shocks In Smallholder Agriculture During The Covid-19 Pandemic, M. Huss, M. Brander, M. Kassie, U. Ehlert, T. Bernauer

All Peer-Reviewed Publications

Millions of smallholder farmers in low-income countries are highly vulnerable to food-supply shocks, and reducing this vulnerability remains challenging in view of climatic changes. Restrictions to limit the spread of the COVID-19 pandemic produced a severe supply-side shock in rural areas of Sub-Saharan Africa, including through frictions in agricultural markets. We use a large-scale field experiment to examine the effects of improved on-farm storage on household food security during COVID-19 restrictions. Based on text message survey data we find that the prevalence of food insecurity increased in control group households during COVID-19 restrictions (coinciding with the agricultural lean season). In …

Push-Pull Strategy Combined With Net Houses For Controlling Cowpea Insect Pests And Enhancing Crop Yields, Seydou Diabate, Thibaud Martin, Lucy Kananu Murungi, Komi K.M. Fiaboe, John Wesonga, John M. Kimani, Emilie Deletre

All Peer-Reviewed Publications

Net houses can be used in tropical environments to protect crops such as cowpea against large insect pests, thereby avoiding pesticide treatments while sustainably mitigating the effects of climate change. We investigated a push-pull strategy to prevent small insect pest outbreaks in a net house. The push component consisted of two stimulus plants, i.e. Cymbopogon citratus and Tagetes minuta, and the pull stimuli consisted of visual cues from blue and yellow sticky traps. Field experiments were set up in central Kenya and conducted during a rainy and a dry season, involving an open field control treatment, and three management treatments …

Novel And Transgressive Salinity Tolerance In Recombinant Inbred Lines Of Rice Created By Physiological Coupling-Uncoupling And Network Rewiring Effects, Isaiah C.M. Pabuayon, Ai Kitazumi, Kevin R. Cushman, Rakesh Kumar Singh, Glenn B. Gregorio, Balpreet Dhatt, Masoud Zabet-Moghaddam, Harkamal Walia, Benildo G. De Los Reyes

Department of Agronomy and Horticulture: Faculty Publications

The phenomenon of transgressive segregation, where a small minority of recombinants are outliers relative to the range of parental phenotypes, is commonly observed in plant breeding populations. While this phenomenon has been attributed to complementation and epistatic effects, the physiological and developmental synergism involved have not been fully illuminated by the QTL mapping approach alone, especially for stress adaptive traits involving highly complex interactions. By systems-level profiling of the IR29 × Pokkali recombinant inbred population of rice, we addressed the hypothesis that novel salinity tolerance phenotypes are created by reconfigured physiological networks due to positive or negative coupling-uncoupling of developmental …
