3) Explain the differences between descriptive and informative abstracts. The points to be covered:

1. The purpose of abstracts. 2. The key parts of each type of abstracts. 3. The length of abstracts.

4) Read and translate the following abstracts paying attention to the underlined word combinations. Determine the type of each abstract (descriptive, informative). Identify the key parts of the abstracts.

Text 3: Sample abstracts

1. Within the EU Austria is in the vanguard of the development of organic farming, with more than 10% of farms and land under organic management. Austria therefore provides an excellent example of what happens when organic production becomes an accepted mainstream mode of farming.

This raises key questions about how agricultural policy actors and market actors react to this growth. Does the increasing share of organic production substantially change the future direction of agricultural and policy development? Or is the growth of the organic sector mainly instrumental, allowing policy and market actors to communicate a positive image while at the same time ramifying conventional approaches?

2. Field experiments were conducted at the research field of the National Cereals Research Institute, Badeggi, Niger State, Nigeria. The experiments were designed as 5 x 4 factorial in Randomized Complete Block and laid out in split-plots arrangement, replicated three times. Results showed that the application of different combinations of organic manure and inorganic fertilizer resulted in significantly better growth and grain yield (2.51 t/ha for 1 t/ha + 20 kg N/ha urea and 2.26 t/ha for 0.5 t/ha + 40 kg N/ha urea), compared to the none application of any form of soil amendment (control) (1.38 t/ha), with the parameters also varying significantly among the soil amendments. The use of combined organic manure and inorganic fertilizer, more importantly, 1 t/ha PM + 20 kg N/ha and the cultivation of the NERICA 1 rice variety, are hereby recommended for the farmers in the experimental area.

3. Potato is a high input intensive and a shallow rooted crop which requires an efficient cropping management to ensure adequate nutrient uptake to attain optimum crop growth. The experiment was conducted with four planting dates (22nd October, 1st, 11th and 21st November) and four fertilizer rates viz. 75, 100, 125 and 150% of recommended fertilizer dose in the region for optimum productivity in a randomized complete block design with three replications. Data was recorded on plant height, leaf, and stem weight, and leaf area index and NPK uptake. Planting date had significant effect on all vegetative characteristics and recorded the highest values at 1st November planting date and lowest in 21st November planting date. Maximum uptake of nitrogen, phosphorus and potassium by leaves, stems and tubers was also observed at 1st November planting date. Plant height, leaf area index, leaf and stem weight increased with increase in fertilizer dose. Thus, the results of this study suggested that optimum planting time (1st November) is very critical for maximum nutrient uptake of the applied fertilizer dose to the potato crop under semi-arid conditions.
