The CO2 exchange of leaves, pods and peduncles was measured in cowpea crops grown at Ibadan, Nigeria, using a portable infra-red gas analysis system. Most leaves had maximum rates of photosynthesis (Pm) of about 1·4 mg CO2/m2/sec and maintained this value for 20 days from full expansion. Early leaves had slightly slower rates. Pm decreased when leaf temperature exceeded 35 °C. The maximum efficiency of photosynthesis, ɛm, was about 2 g CO2/E (0·045 mol CO2/E). ɛmdecreased with temperature for leaves, but increased for pods. The latter response probably results from the effect of the high CO2 concentrations within the pod on the ribulose disphosphate carboxylation reaction. Water shortage reduced Pm but not ɛm. Pods and peduncles had a slightly negative CO2 exchange rate at light saturation but this was considerably less than the rate of CO2 evolution in the dark.

In the 350–600 mm seasonal rainfall ecological zone in northern Syria three-course rotations are commonly practised under rainfed conditions. The precipitation regimes at three sites in this ecological zone have been examined. These have been shown to exercise a powerful influence on crop management, and an enhanced understanding of the effect of precipitation on crop productivity would therefore assist in the development of improved strategies of agronomic and rotational management. Considerable variability has been demonstrated in characteristic elements of the precipitation regime at the selected sites and this has indicated the unsoundnesa of applying general management recommendations to the ecological zone as a whole.
The growth and development of cowpeas (Vigna unguiculata)under tropical field conditions: 2. Accumulation and partition of dry weight

The pattern of dry weight accumulation and partition of cowpea crops grown in Nigeria is described. For the first 50 days, increase in dry matter was proportional to intercepted radiation. Differences in dry weight between crops were due equally to variations in incident solar radiation, the fraction of this radiation intercepted, and the efficiency with which it was used. The variation in total pod weight from 206 to 312 g/ma resulted from differences in number of pods, mean pod weight being constant. The pod weight ratio was relatively constant and there was a strong relationship between final number of pods and total plant dry weight.

The pattern of leaf growth and death was followed in stands of cowpea grown in the field at Ibadan, Nigeria. Temperature affected this pattern. Leaf area index increased quicker and leaf death started sooner during warm seasons. Individual leaves died while pods at the same node were filling. The rate of leaf appearance increased with temperature and the duration of expansion of individual leaves decreased so that a constant number of leaves were expanding at one time. The mean rate of expansion of individual leaves increased with temperature proportionately more than the duration decreased, hence final leaf size increased with temperature. Base temperatures for leaf appearance and leaf expansion were 16 and 20 °C respectively.

Simple methods are described for the analysis of daily rainfall measurements. The distinctive feature is that each year provides one number for any event or characteristic of interest. The resulting observations are then analysed, assuming that they are a simple random sample from a single distribution. An estimate of the probability of an event can be made directly from its relative frequency of occurrence, or alternatively a distribution (such as the normal) can be fitted. The methods are applied to agronomic questions on dry spells, the start, end and length of the growing season, and the distribution of amounts of rainfall through the year. Examples are given from Nigeria and India.

A probabilistic model of daily rainfall can be used to derive results of potential value to agriculture. A simple example shows how this model works, but more realistic models are also fitted, using standard statistical computer packages, and examples of the results are presented graphically. The modelling approach is compared and contrasted with direct methods of analysing daily rainfall.

Growth and water use of sole crops and intercrops of morphologically contrasting maize and pea cultivars were measured in two years. The maize cultivars were Nancis with erectophile and Sophy with planophile leaves and the pea cultivars Maro a leafy pea and Princess a semi-leafless pea. In the first part of the season water use was lower for sole maize but intercrops and sole pea used similar amounts of water. By 90 days after sowing, when peas had matured, all crops had used similar amounts of water. Maize had slightly greater water use efficiency than peas. Cultivars Nancis and Princess tended to have greater water use efficiency than Sophy and Maro respectively. Intercrops produced more dry matter than sole crops and therefore had consistently greater water use efficiencies.
