Effects Of Nitrogen Fertiliser On Nitrate Leaching And Production Of Autumn-Sown Italian Ryegrass In A Double-Cropping System On A New Zealand Dairy Farm, Errol R. Thom, A. A. Judge, R. N. Jensen, M. S. Sprosen, Sterwart F. Ledgard, W. D. Catto Aug 2023

Effects Of Nitrogen Fertiliser On Nitrate Leaching And Production Of Autumn-Sown Italian Ryegrass In A Double-Cropping System On A New Zealand Dairy Farm, Errol R. Thom, A. A. Judge, R. N. Jensen, M. S. Sprosen, Sterwart F. Ledgard, W. D. Catto

IGC Proceedings (1997-2023)

On intensive dairy farms in New Zealand, winter Italian ryegrass crops are combined with summer maize silage crops in double-cropping systems. Limited data (Davies & Neilson, 1975) showed variable ryegrass yield responses to nitrogen (N) fertiliser when grown after maize. Nitrogen leaching losses were not measured in this experiment but Ledgard et al. (1988) showed that late autumn/early winter N applications are vulnerable to leaching. Different rates of N fertiliser were applied to Italian ryegrass grown after maize to assess yield responses and levels of nitrate leaching.


A Glass Bead Semi-Hydroponic System For Intact Maize Root Exudate Analysis And Phenotyping, Martha G. Lopez-Guerrero, Peng Wang, Felicia Phares, Daniel P. Schachtman, Sophie Alvarez, Karin V. Van Dijk Dec 2022

A Glass Bead Semi-Hydroponic System For Intact Maize Root Exudate Analysis And Phenotyping, Martha G. Lopez-Guerrero, Peng Wang, Felicia Phares, Daniel P. Schachtman, Sophie Alvarez, Karin V. Van Dijk

Department of Agronomy and Horticulture: Faculty Publications

Background: Although there have been numerous studies describing plant growth systems for root exudate collection, a common limitation is that these systems require disruption of the plant root system to facilitate exudate collection. Here, we present a newly designed semi-hydroponic system that uses glass beads as solid support to simulate soil impedance, which combined with drip irrigation, facilitates growth of healthy maize plants, collection and analysis of root exudates, and phenotyping of the roots with minimal growth disturbance or root damage. Results: This system was used to collect root exudates from seven maize genotypes using water or 1 mM CaCl2, …

Purdue Fruit and Vegetable Research Reports

This is a compilation of 19 research trial reports from six land-grant universities in the midwestern United States. Crops include bok choy, cantaloupe, cucumber, pepper, pumpkin, sweet corn, squash, tomato, and watermelon. Several crops were evaluated in high tunnels or hoophouses. Most trials evaluated different cultivars or varieties, including one investigating cantaloupe variety influence on cucumber beetle presence and incidence of bacterial wilt. Four reports addressed specific growing practices: the use of poly-coated urea to supply nitrogen to sweet corn, biochar use in a high tunnel bag culture system, use of cereal rye cover crop in butternut squash, and pollinizer …

Using Sex Pheromone Traps In The Decision-Making Process For Pesticide Application Against Fall Armyworm (Spodoptera Frugiperda [Smith] [Lepidoptera: Noctuidae]) Larvae In Maize, Ivan Cruz, Maria De Lourdes Corrêa Figueiredo, Rafael Braga Da Silva, Ivana Fernandes Da Silva, Cristiane De Souza Paula, John E. Foster

Department of Entomology: Faculty Publications

The fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae), is a major pest of maize and frequently demands control measures. The timing of insecticide application is a key factor in determining its efficiency, so an experiment was designed to investigate this. Application of insecticide was based on three criteria: (i) the number of trap-caught moths in a Delta-type trap with a commercial sex pheromone lure placed in the center of the target area, soon after plant emergence; (ii) the percentage of plants exhibiting pinhole-type damage (10% or 20%), and (iii) the percentage of plants exhibiting shot hole–type damage (10% or 20%) …
