The British Tropical -Agricultural Mission (BTAM) is a unit of the overseas Development Administration and consists of a group of eight to ten specialists in the fields of soil management, agronomy, plant protection, sociology, ecology, economics, animal production, pasture production and agro-forestry, working in a supportive and training capacity with the Bolivian Centro de Investigaci6n Agricola Tropical (CIAT), since its formation in 1976.

In the past years, several machine-learning-based techniques have arisen for providing effective crop protection. For instance, deep neural networks have been used to identify different types of weeds under different real-world conditions. However, these techniques usually require extensive involvement of experts working iteratively in the development of the most suitable machine learning system. To support this task and save resources, a new technique called Automated Machine Learning has started being studied. In this work, a complete open-source Automated Machine Learning system was evaluated with two different datasets, (i) The Early Crop Weeds dataset and (ii) the Plant Seedlings dataset, covering the weeds identification problem. Different configurations, such as the use of plant segmentation, the use of classifier ensembles instead of Softmax and training with noisy data, have been compared. The results showed promising performances of 93.8% and 90.74% F1 score depending on the dataset used. These performances were aligned with other related works in AutoML, but they are far from machine-learning-based systems manually fine-tuned by human experts. From these results, it can be concluded that finding a balance between manual expert work and Automated Machine Learning will be an interesting path to work in order to increase the efficiency in plant protection.

Having briefly described the high country in terms of its environment, potential pasture production, and suitability of particular pasture species, we need to consider development strategies for sustainable animal production. Important points are: Type of animal Provision of winter feed Land and management requirements to grow young stock Subdivision of land into its various natural units to firhi the year round stock feed requirements Efftcient use of fertilisers General strategies of pasture development using legumes, grasses and nutrient cycling.

A Site

At present, only a small proportion of livestock in developing countries are kept on cultivated pastures (Williamson and Payne, 1978).This paper is therefore more concerned with the intensification of the pasture production and the levels of animal production which may be achieved. In general, the pastures which may be cultivated in an area and the ways open for their utilization are related to the ecology of that area (Bogdan, 1977; Skerman, 1977). The factors which determine the natural vegetation to be found on a site, and the distribution of the major plant communities in developing countries, will therefore be reviewed first. Then, certain ecological zones which show promise for the intensification of pastures will be selected and, for each, some of the possible lines of development will be discussed.

Inadequate pasture growth from September to November has been a major constraint on animal production at Limestone Downs, Port Waikato. In an attempt to address this, urea was applied by air in two applications per year (late autumn + winter) at rates up to 250 kg N/ha/year for each of 3 years (2004-2007).

This collection of papers does four significant things: 1. It concentrates on hill country. 2. Precisely defines the research environment in pasture levels and animal production terms. One can clearly see the consequences in animal production at different times of the year when pre-grazing and residual herbage levels are defined and varied and to see the effects of different grazing systems at these pasture levels. Much better than high vs low stocking rates. 3. Attempts to set pature targets as well as animal production targets. 4. Defines critical pasture DM levels both below which pasture production is reduced, and above which control is lost. The proximity to these critical levels will, for a farmer, more precisely define the grazing management system he should adopt and the levels of animal production he should be able to achieve

Natural Pasture

Pasture and animal production from fertilised pastures with varying proportions of sown grass (0-60%) were recorded and compared. The presence of sown grass increased pasture production when compared to natural pasture, but no difference was detected in liveweight or wool production between the var- ious pastures. It is doubtful whether sowing of introduced grasses for wool production can be justified at the levels of grazing intensity usually adopted on the Northern Tablelands.
