The Council for Scientific and Industrial Research (CSIR) is the foremost national science and technology institution in Ghana. It is mandated to carry out scientific and technological research for national development. The Council was established in its present form by NLC Decree 293 of 10th October, 1968 and re-established by CSIR Act 521 of 26th November, 1996. The Council, however, traces its ancestry to the erstwhile National Research Council (NRC), which was established by the Research Act 21 of August, 1958, a little over a year after i [...]
The effect of spacing and age of transplant on the yield of eggplant, Solanum melongena (Black-beauty) on the Accra Plains [Ghana]
Ocloo, G. [jul1979]
The effect of spacing and age of transplant of egg plant (black beauty, aubergine variety) on yield is reported. Three-week old and five week old transplants in combination with 1 m x 1 m, 1 m x 0.75 m and 1 m x 0.50 m spacing were used. Younger transplants in combination with closer spacing of 1 m x 0.50 m gave the highest average yield of 9.45 t/ha whereas older transplants with wider spacin ...

Effects of intensity and time of defoliation on growth and yield of cowpea (Vigna unguiculata) cv. PI 1239
Okyere-Boateng, G. [jun1981]
Cowpea variety PI 1239, a vigorous spreading type was defoliated by removing one or two leaflets at the vegetative and reproductive stages and throughout growth. Defoliation had no significant effect on plant dry weight, the number of seeds per pod, the average pod length and the 100-seed weight, but affected the leaf area index at the vegetative and reproductive stages. Number of leaves remov ...

The effects of ethrel (2-chloroethyl phosphonic acid) on the flowering and fruiting of cucumber (Cucumis sativus L.)
Amoabin, S. [oct1978]
A growth regulator, ethrel (2-chloroethyl phosphonic acid) was applied on cucumber as a foliar spray (at 3-4 and 5-6 true-leaf stages) and coupled with or without pruning, to evaluate its effect on flowering and fruiting. The number of fruits per plant increased but the treatment had no effect on fruit weight. The dry matter content of fruit and internode length were reduced by ethrel, and the ...

Studies on the growth, flowering and yield of Nevi, Citrullus lanatus var Neri (Thunb) Nakai and Mats
Sakyi-Dawson, O. [jun1980]
The effects of pruning and irrigation frequency on the growth, flowering and yields of Citrullus lanatus are reported. Pruning and lateral branches reduced the length of the main stem and led to early flowering. Pruning to two stems per plant increased the total dry weight of the plant, while pruning to a single stem per plant decreased it. No effect on the pistillate to staminate flower ratio ...

Bakang, J-E.A. [jun1981]
The biology of the shear butter tree, its growth, yield, pests and diseases, harvesting, the inefficient traditional extraction and processing of shea butter, marketing and the industry as a whole are discussed. The Shea nut tree forms part of the savanna vegetation of Northern Ghana, growing wild and has not been cultivated despite its oil producing potential. The tree is in danger of extinct ...

Konogini, J.Y. [may1980]
The influence on germination of garden egg seeds by fruit maturity and chlorox, a surface sterilant with possible growth promoting property, is reported. Three different fruit maturity stages were used, red, yellow and white or mature green stage were considered. The red stage gave the highest percentage germination and the white gave the lowest. Chlorox-treated seeds had higher rate and total ...

Owusu, K.D. [jun1979]
The nutrient spray, Samppi No. 3 liquid fertilizer (labelled as multiple micro-element foliar spray) was tested on two cultivars of onion, the Bawku, and Texas Early Grano, for its effects on bulbing. Both varieties responded similarly to the treatment. Plant size increased with increasing concentration of 2 ml/l of the spray at the early growth stages in addition to healthy, vigorous growth, ...

Lagudah, S.E. [jun1980]
The performance of local and exotic cultivars of cowpeas using different planting time was evaluated. First planting was in June, and second in October when higher daily sunshine duration, higher temperatures, shorter daylength and rainfall occur. The exotic lines possessed higher number of seeds per pod and were generally free of pre-flowering disease symptoms. Cultivars TVX 1836-013J and TVX ...

Logah, S. [jun1980]
The effect of post-harvest ripening on the germination of garden-egg seeds obtained at various stages of maturity, namely mature (marke-table), white, yellow and red ripe, is reported. Seed extraction was done after parts of the fruits were ripened to the red stage, and the red ripe softened on storage. High percentages of germination in all fruits ripened to the soft red stage occurred, the h ...

Quashigah, P.K. [jun1980]
The effects of planting rate per hill and moisture stress on the yield of maize is reported. Four treatments containing 1, 2, 3 and 4 plants per hill were used and the plots irrigated when moisture stress was at pF values of 2.5, 3.0 and 3.5. At the frequent irrigation (pf 2.5), no difference was found in yield between 1 to 3 plants per hill. Yields, leaf area index, stover yield and yield com ...
