Growth regulators in the development of potted Epidendrum radicans orchid

Epidendrum is a terrestrial orchid with great potential for commercialization. However, its considerable height makes it difficult for transport and commercialization. Many species have been controled with growth regulators, including orchids and other ornamental plants. The aim of this study was to evaluate the efficiency of two plant growth regulators, paclobutrazol and chlormequat chloride (CCC), on the vegetative...

Effect of honeybee (Apis mellifera) pollination on seed yield and yield parameters of Guizotia abyssinica (L.f.)

A flower of Guizotia abyssinica (L.F.) opens and liberates pollen early in the morning, the style emerges about midday and the plant is thus basically self-sterile. Hence G. abyssinica is a cross pollinated crop with cross pollination percentage ranging from 0 to 100 percent. Locally, the role of honeybees’ pollination is still poorly understood and till now is not sufficiently appreciated. Hence, this experiment...

Effectiveness of cypermethrin against diamondback moth (Plutella xylostella L.) eggs and larvae on cabbage under Botswana conditions

The efficacy of cypermethrin against the diamondback moth (DBM) on cabbage was studied at Botswana College of Agriculture, Gaborone, Botswana. Using five concentrations of cypermethrin: 1.2, 1.6, 2.0, 2.4 and 2.8 g/L, bioassays were conducted against DBM eggs and second instar larvae at 30±5°C. Each treatment was replicated three times. Probit analysis was used to determine LD50 and LD90 values for the...

Effect of agronomic practices on growth, dry matter and yield of Rajmash (Phaseolus Vulgaris L.)

Rajmash (Phaseolus vulgaris L.) is an important cash crop widely grown under temperate and subtropical regions. Being a pulse crop it is good substitute of vegetables. To sustain the productivity of such a wonder crop and fulfill the nutritional demand of the ever growing population under changing climate it is necessary to apply integrated agronomic approaches. Integrated management of agronomic practices plays a...

Success factors for sustainable irrigation development in Sub-Saharan Africa

Majority of farming in sub-Saharan Africa depend solely on rainfall for food production. This results in low productivity and famine, especially during the dry season when there is little or no rainfall. Owing to its far reaching benefits, irrigation systems have been identified and adopted globally as a key approach to addressing agricultural water challenges. However, the annual growth rate of irrigation systems in...

Effect of different spacing on newly planted guava cv. L- 49 under ultra high density planting system

Trees of guava (Psidium guajava L.) cv. Sardar were planted in September, 2010 at 2.0 x 2.0, 2.0 × 1.5, 1.5 × 1.5, 2.0 x 1.0 and 1.0 × 1.5 m spacing in 6.0 x 6.0 m size blocks to determine the effect of planting distance on tree growth, light interception, chlorophyll content, leaves Nitrogen, Phosphorous, and Potash (Potassium) (NPK), flowering, yield and quality parameters. The experiment was laid...

Role of phosphorus in chickpea (Cicer arietinum L.) production

India is a highly populated country under the category of developing nations. The protein requirement of most of the people is fulfilling through pulses. Production of pulse crops and their yield stagnation last so many years. It has been estimated that India’s population would reach 1.68 billion by 2030 from the present level of 1.21 billion. Accordingly, vision of Indian Institute of Pulse Research, 2030, the...

Variation, correlation, regression and path analyses in Eruca sativa Mill.

In the present study variation, correlation, regression and path coefficients in Eruca sativa Mill. were analyzed. Great variations were observed with agronomic and oil quality traits in Eruca. Partial correlation, stepwise regression and path analyses indicated that the contributions of siliqua number per plant (X7), seeds per siliqua (X8), 1000-seed weight (X9) and siliqua number of main raceme (X6) to seed yield per...

Influence of food resource on the development of Liriomyza trifolii Burgess 1880 (Diptera-Agromyzidae)

In order to limit the devastation caused in the celery (Apium graveolens L., 1753) plots by Liriomyza trifolii Burgess in Nkolondom, (Southern Cameroon), farmers proceed to the anarchic use of synthetic insecticides in addition to the pruning of the infested leaves as sanitary harvests. These infested leaves resulting from sanitary harvests are immediately abandoned in the furrows. The main objective of the present...

Ethiopian beef carcass characteristics

This study was conducted to evaluate beef carcass characteristics of cattle slaughtered at local abattoirs in Ethiopia. About 10% of carcasses (3080) were collected from Adama, Hawassa, Mekelle and Kombolcha abattoirs between August 2013 and January 2014. The results of the study showed that 98.56% of cattle slaughtered were indigenous cattle while 1.44% was Holstein Frisian. The average carcass weight of indigenous...
