When Indonesia finally received de jure independence in December 1949, the infant republic faced a range of serious problems, but nowhere were the problems more pressing than in the field of economic policy. In contrast with the Philippines and India, where the USA and Britain had honoured previous commitments and granted independence in 1946 and 1947 respectively, the refusal of the Netherlands to recognise the 1945 declaration of independence had led to four years of bitter and destructive fighting. Infrastructure on Java and elsewhere, already damaged during the Japanese occupation, deteriorated further after 1945, and by the end of the decade most of the important export industries were producing only a small fraction of their pre-1942 output. Smallholder agricultural output in Java was also well below pre-1942 levels. De Vries observed that many seed farms had been destroyed, irrigation systems had not been maintained and “vast areas of hill country” had been damaged by soil erosion. In the final years of the Japanese occupation, the Japanese army commandeered large amounts of rice, while the widespread issue of Japanese banknotes caused mounting inflation. Food was scarce everywhere and those with little or no land were most severely hit; most demographers concur that the population actually declined in Java after 1943, indicating a sharp increase in mortality.

Farm System

The improvement in forage quality and quantity of summer-dry hill country pasture resulting from the introduction of clover is well recognised. However, ensuring the persistence of the commonly availablecultivars is challenging, in the face of seasonal moisture stress, intensive grazing, competition from established well-adapted pasture species, low soil fertility and low soil pH – conditions typical of the East Coast of the North Island. Here we quantify the value proposition associated with the introduction of white clover into a case study on a Gisborne sheep and beef farm, using a six-step process. A topographically explicit approach is taken, using an understanding of the underlying spatial variability, based on a combination of soil and pasture measurements, APSIM simulation modelling of pasture growth and farm system modelling of enterprise performance. We show that from a baseline of a typical low-fertility, diverse species hill country pasture, white clover introduction can increase spring and summer forage consumption by 17%, enabling inclusion of an additional 6-month bull finishing enterprise generating a 32% greater carcass weight production and leading to a 49% improvement in farm system EBIT. This represents a positive net present value of over $360,000 for the original investment in white clover establishment into existing pastures.

Visual Impact

Considerable effort is expended measuring pasture parameters that relate to animal perform mance. Traditionally farmers have used visual impact and experience as their method of pasture assessment to make management decisions. The simplest measurement collected by researchers, pasture height, is developed to the point where it can be used as a guide to predict pasture mass and animal performance. This paper presents relationships between height and mass for improved pastures in summer dry North Island hill country. A pasture 5cm tall will give hogget growth of 60 gjday in summer, 90 in autumn, 100 in winter and 200 in spring. Similarly 5cm will be 2250 kg DM/ha in summer, 1900 in autumn, 1520 in winter, 1640 in spring and 2200 in late spring. Keywords: Height, mass, predictor, grazing, quality, animal performance, feed levels, parameters, pasture.
