Abstract:

Fertility-building crops (FBCs) offer the opportunity to alleviate the costs of inorganic fertiliser by providing an alternative supply of available nitrogen (N) in soils. A survey of relevant literature reviewed the types of FBCs, their nitrogen accumulation potentials, residue characteristics, and subsequent release patterns. It also identified a paucity of data concerning the response of different species to UK climatic, soil, and management conditions. In order to investigate these relationships further pot and field trials were established in 2007 at the Royal Agricultural College, Cirenc

Assignment (MSc) -- University of Stellenbosch, 2004.<br>ENGLISH ABSTRACT: In an integrated crop-livestock production farm, the profitability and sustainability of farm production is dependent on the crop rotation strategy applied. Crop rotations have historically been applied to maintain long-term profitability and sustainabiliry of farming production by exploiting the jointly beneficial interrelationships existing among different crop types and the animal production activity.

This thesis is composed of two essays that investigate whole farm planning and crop marketing in western Kentucky. In the first essay, contracting decisions between food corn producers and a mill are analyzed to observe factors affecting the bushel amount farmers contract. Unbalanced panel data containing seven years’ worth of pricing and contract information are used with a fixed-effects model to generate parameter estimates and quantify their effect on bushels contracted. It was found that contract attributes, market condition, and relationship-specific assets had a significant effect on pro

Abstract:

A model of local elevator basis levels was developed to quantify the response of corn, soybean and hard red spring wheat basis to a set of predefined predictors. Basis data from 2013 ? 2016 for 12 grain elevators in Eastern North Dakota were collected. A maximum likelihood mixed effect model was used to test the significance of alternative predictor variables and further divided the residuals into temporal and spatial components. The results indicate that the base model was able to explain 57 to 87 percent of the local basis variability for the selected crops at the individual elevators. In

Abstract:

Treatment of endophyte-infected tall fescue [Lolium arundinaceum (Schreb.) Darbysh] with the broad leaf herbicide Chaparral® can mitigate fescue toxicosis and enhance forage quality by suppressing seedhead emergence. Applying the herbicide to fescue pastures also reduces forage mass and promotes severe spot grazing when pastures are continuously grazed. A grazing experiment was conducted with steers (2013) and heifers (2014) to evaluate animal and plant responses in fescue-bluegrass (Poa pratensis L.) mixtures treated with Chaparral to determine the effects of grazing management on pasture car

The use of nitrogen (N) fertilizer is generally restricted on mixed species forage systems due to its stimulatory effect on grasses which increases competition with legume species. Reduced legume growth from this competition can compromise forage nutritive value and prospective yields. The controlled-release nature of several enhanced efficiency fertilizer N products holds the potential to improve legume persistence in mixed species pastures while providing supplemental N required by the grass component.

However, grazing management for increased seed production during flowering in the establishment year strongly influenced balansa clover regeneration.

Agroforestry systems that intercrop food crops with rows of hardwood species for the purposes of timber production have not been practiced.

Modern society is forced to deal with two main problems: a growing scarcity of resources and a growing production of waste. The unsustainability of the current linear economic model “make, use, dispose” originated the concept of “circular economy” that aims to reduce the environmental impact through measures in favour of a more sustainable development, such as the use of renewable energy and waste recycling. Unlike the traditional linear model, the circular economy keeps resources in use for as long as possible, extracts the maximum value from them whilst in use, then recovers and regenerates

The use of annual-based pasture and/or annual crops is now common practice in the higher rainfall regions of southern Australia where livestock grazing is the traditional practice.

For environmental reasons farming systems used in the higher rainfall regions should target the use of more perennials in the landscape, but this should not be done at the expense of farm productivity or profitability.

碩士<br>國立中央大學<br>土木工程學系<br>107<br>In this study, a system dynamic model (VENSIM) was applied to establish an irrigation water management model for mixed cropping system in Central Taiwan. The experimental site of 209 ha located at the upstream of Choushui river consists of paddy rice and upland mixed crops. There is a conjective use of channel water and groundwater for irrigation purpose in addition with rainwater. The cropping area consist of 70% paddy rice and 30% upland crops. VENSIM model was simulated for the first cropping season of years 2015 and 2016. The input data comprised of hydrolo

碩士<br>國立中央大學<br>土木工程學系<br>105<br>Taiwan's agricultural water accounts for about 70% of the total nation’s water consumption in which paddy field irrigation has the largest proportion. Farmers choose to irrigate crops with water extracted from irrigation channel or pumped groundwater. The groundwater pumping issue has recently become a great concern in Taiwan. Taking into account the farmers’ irrigation experience and in-field irrigation operating, this study applies system dynamic model to establish an irrigation water management model for mixed paddy rice and upland crops fields in central Ta

碩士<br>國立中央大學<br>土木工程學系<br>106<br>The study area is located upstream of the Choushui river alluvial fan. It is an irrigation system that mixes paddy rice and upland crops. The irrigation water in the study area is mainly from rainfall and channel water. In the event of drought or when the channel water is insufficient, farmers will pump groundwater for irrigation. However, the littoral area of the Choushui river alluvial fan has subsided, which is caused by long-term groundwater over pumping, and the central of subsidence area is gradually moving to inland area. Therefore, the purpose of this s
