- ItemEFFECTS OF PHOSPHORUS, POTASSIUM AND BORON DIM THE AGRONOMIC PERFORMANCE OF GROUNDNUT (Arachis hypogaee L.) IN NIGERIA(1965-06) HASSAN, MOHAMMED GIDADOInvestigations were carried out for two years each at Samaru in the Northern Guinea and Mokwa in the Southern Guinea savannah to observe the response of groundnut (Arachis hypogaea L.) to varying levels of phosphorus (6, 16 and 24kg P ha -1 ), potassium (0, 20 and 40kg ha -1 ) and boron (0.0 and 0.5kg 0 ha - 1 ) . At Samaru, increasing the level of phosphorus from 8kg to 16 and 24kg P ha-1 enhanced pod yield by an average of 23 and 16%, respectively. Other yield attributes such as mature pods per plont, shelling percentage and kernel weight were only slightly increased up to 24kg P ha-1 . In Mokwa, the application of 16kg P ha -1 appeared adequate for optimum groundnut production. The addition of potassium fertilizer generally did not result in increased pod production. However, at Mokwa where the level of soil potassium was relatively low there was a tendency for increased pod yield in the presence of added potassium fertilizer. Application of boron had no effect on groundnut production except in 1984 at Mokwa where the use of 0.5kg 0 ha-1 significantly increased the haulm yield

- ItemEDUCATION AND THE DEVELOPMENT OF FARMING IN TWO AREAS OF ZAMBIA(1972-05) VANZETTI, N.R.During the last ten to fifteen years there has been a substantial increase in ducational facilities in developing countries, in order to provide skilled manpower for both urban and rural development. There is now a need to see if education ha3 contributed to this development, not only at the national level, but also in the villages spread throughout the rural areas. This hesis is the result of a quantitative investigation into how education has contributed to the improvement of the farming of the 239 family cultivators surveyed by the Universities of Nottingham and Zambia Agricultural Labour Productivity nvestigation (UNZALPI) in the Mumbwa and Katete districts of Zambia. In this study, education has been defined broadly to include schooling, farm training, contact with the agricultural extension service, non-farm employment and general experiences. The contribution of these educational experiences, both directly to production and indirectly through the stages of the process of the adoption of improved practices, was examined.The three main findings of the study can be summarised as follows : (i) At the level of farming in the survey areas, motivation was found to be an important pre-condition for the improvement of farming. The schooling of the cultivators contributed to this motivation, but its contribution appeared to be constrained by community values. Those who had been employed in urban or rural areas were not more often than the others motivated to improve their farming; (ii) The extension service, although it was regarded as the main source of the knowledge, skills and management needed for the improvement of farming, was notregarded as being of significant help in this respect. Consequently, the cultivators' opinions of this service were low, as was the morale of the staff. The staff were not entirely to blame for this, and the service must be reorganised in such a way as to raise both the morale of the staff and their status in the rural community;(iii) If school-leavers are to be persuaded to return to their villages in order to commence farming, they must see that farming in a village situation can be profitable. This means that higher priority must be given to adult education : both motivational education and farm training. School-leavers must also be given every assistance to fulfil their aspirations for a higher standard of living if they are to be prevented from migrating to urban areas, or from settling back into traditional patterns of behaviour.
- ItemAN APPRAISAL OF MOCAP AND OTHER SELECTED NEMATICIDES FOR THE CONTROL OF MELOIDOGYNE SPP IN TOMATOES(1973) OKATAHI, STEPHEN SALAMIIn an attempt to find a substitute for Nemagon five nematicides were tested for the control of rootknot nematodes on tomato. Mocap was quite effective in root-knot control in nursery seedlings but phytotoxicity was observed when applied at dosages equal to or higher than 10 kg a.i per hectare, the dosage recommended by the manufacturer. Although Nemacur was very effective in the nursery, it has a very high mammalidn toxicity which makes the compound rather dangerous to be recommended now. DD and Basamid were found effective. Basamid however stays too long in the soil at phytotoxic level during the rainy season (more than four weeks). Vydate was the most effective compound in the trial in terms of rootknot control and fruit yield increase; but it has a high oral toxicity, though its dermal toxicity is low. Yield increase ranged from 10% in Mocap, to 87% in Vydate-treated crop at the recommended dosages

- ItemFIELD CAPACITIVE PERFORMANCE OF COTTON PICKING MACHINES IN ARIZONA(1975) Gwarzo, Aminu SalihuInformation on the time study of mechanical cotton picking is useful to farm managers, researchers, and cotton harvesting machinery designers. Using operational analysis, time study information can be used to improve the field performance of cotton picking machines, and yield clues for machine design changes. This report presents a time study of mechanical cotton picking made during the 1974 harvest season. The time study information was used to compute the machine field capacitive performance. Factors affecting the performance are discussed. A method for mechanizing the collection of the time study information was designed for installation and testing

- ItemEFFECT OF NITROGEN AND PHOSPHORUS ON YIELD AND YELLOW BERRY DEVELOPMENT IN BREAD AND DURUM WHEAT(1976) Negedu, SamuelThis study was initiated to evaluate the effect of N and P fertilization on yield and yellow berry development in bread and durum wheat. Two wheat varieties, Cocorit 71 (durum) and Cajeme 71 (bread wheat), were grown under irrigation at The University of Arizona Experimental Farm, Marana, on Pima clay loam soil during the 1976-77 growing season. Twelve treatments involving four levels of N and three of P were arranged in a randomized block design with six replications. These were 0, 168, 252 and 336 kg N/ha and 0, 44.8 and 89.6 kg P/ha. Prior to harvest, samples were taken and analyzed for number of heads, head weight, straw weight, and grain weight. Grain yield was determined at harvest. Percent yellow berry content, number of grains per head and number of grains per 25 g were determined later. Yellow berry and vitreous grains were analyzed for N content. Grain yield increased with increased N and P but N in excess of 252 kg/ha decreased yields of both varieties slightly. The maximum grain yields of both varieties were associated with 89.6 kg P/ha. Yield increases were primarily due to production of more heads and grains as well as increase in grain weight per unit area. Percent yellow berry decreased with increased N with no significant effect of P. Percent N in yellow berry grains was generally lower than in vitreous grains
- ItemSTUDIES ON POPULATIONS AND FEEDING HABITS OF TRINSRVITERMSS GEHINATUS (WASMANN), (ISOFTERA) AND ITS SIGNIFICANCE IN PASTURES IN THE SOUTHERN GUINEA SAVANNA ZONE OF NIGERIA(1976-11) CLIFFORD, EZEKWESIRI OHIAGUThe main objective of this study was to assess the damage to grazed pastures in the Mokwa area of the Southern Guinea savanna zone of Nigeria by Trinervitermes geminatus (Wasmann) (Isoptera, Termitidae, Nasutitermitinae) and to determine its role as a competitor with grazing livestock. In Nigeria, T. geminatus is the only species which cuts down standing grass and at the same time is sufficiently abundant to be considered a potential threat. T. geminatus builds domed-shaped mounds which are highly aggregated and serve as breeding and storage sites. Some of these mounds are subsequently abandoned and are either eroded away or are reoccupied by the nonmound building species of the same genus or other termites notably Cubitermes sp., Promirotermes sp. and Microtermes spp. During the rainy season, new mounds are constructed and old mounds are enlarged. Population density of T. geminatus was estimated in grazed and ungrazed areas of a secondary woodland, as well as in a primary savanna woodland. Populations were low (203/m ; 232 mounds/ha) in the areas of study and seasonal fluctuations in them were indicated. Decrease in population during the dry season, coincided with the period of active foraging and intense predation, and they increased during the rains. Following the flight of alates in July/August, populations again declined. The foraging habits of T. geminatus and the quantity of grass removed were investigated. Foraging in the Mokwa area was in early morning or late afternoon and lasted about 2-3 hours. It was greatly influenced by environmental factors such as rain, soil surface temperatures and relative humidity. Grass production was estimated at approximately 3000 kg/ha/annum, and of this quantity cattle consumed approximately half the annual production 48%). A method was developed for quantifying the amount of grass harvested by T. geminatus, and following this method, the quantity of grass removed by this species was estimated as representing 3.5% of the total annual grass production. Therefore, the quantity of grass removed and hence made unavailable for cattle consumption was insignificant in this locality. Although, field and laboratory investigations on the choice of grass indicated a strong preference by T. geminatus for Andropogon gayanus, a grass species equally preferred by cattle, they hardly competed for it in the Mokwa area. It is however suggested that the impact of grass harvesting by T. geminatus would be relatively greater in areas with high populations of termites and in overgrazed pastures especially during periods of drought when grass production is lowered by poor management or low rainfall
