 Title:

Study effect of IBA hormone levels on rooting in micro cuttings of tea (camellia sinensis L)

 Author (s):

Sirous Bidarigh and Ebrahim Azarpour

 Abstract:

There has been a steady demand for production and supply of cuttings of different varieties for tea gardens in Iran. In order to study the effect of indole-3-butyric acid (IBA) hormone levels (0, 0. 1; 0.5, 1 and 3 mg/L) on rooting in micro cuttings of tea (Camellia sinensis L.), an experiment as RCBD with four replications was conducted during 2010 at Research Laboratory of Faculty of Agriculture, Lahijan University in Iran. The culture bed was contained MS, sucrose (3%) and agar (75%). The results show that IBA hormone levels on root length and root number in micro cuttings of tea had a significant difference in 1 % probability level. The highest root length (17.22 mm) and root number (4.93) in micro cuttings of tea were obtained with application 1mg/L IBA. The lowest root length (3.17 mm) and root number (0.68) in micro cuttings of tea were obtained with application 0mg/L IBA.

Title:

Effect of amaranth: maize flour ratio on the quality and acceptability of ugali and porridge (Kenyan cereal staples)

Author (s):

Violet K. Mugalavai

Abstract:

Food and nutrition security is a major global concern, especially in the developing countries. Currently, many countries in sub-Saharan Africa depend on a narrow base of food, a situation which minimizes variety in food production and contributes to insecurity in food and nutrition. This situation can be highly improved by considering highly nutritious crops that have domestication potential, such as the amaranth grain, which is richer in protein and other mineral elements when compared to commonly consumed cereal grains. The amaranth grain is currently a highly ignored crop, and yet it is very easy to grow, and its survival in harsh conditions also guarantees its yield. In this paper, the knowledge that the Kenyan North Rift farmer and consumer has of the amaranth grain plant was established in a survey. Literature sources were used to lay out the nutritive value of the amaranth grain, and nutrition education relayed to 250 randomly sampled consumers and farmers, so as to justify the need for its adoption as a cash/food crop. The functional properties (cook paste and water absorption) and culinary characteristics (colour, texture, flavour) of commonly consumed products (ugali and porridge) which were made in varying treatments of amaranth flour: maize meal flour (100:00; 80:20; 70:30; 60:40; 50:50) was determined. Data were managed using SPSS version 18. The survey results established that the knowledge that the farmer and consumer had on the amaranth grain was minimal. Time taken for the samples to turn viscous reduced with increasing amounts of amaranth flour, which also took the least time and lowest temperature to form a stable gel. The porriber and ugaber composites with high amounts of amaranth grain flour (80:20) were the most acceptable, and from the nutritional point, the most nutritious. Increased nutritional awareness, production and consumption of grain amaranth products may be the way to better food and nutrition security.

Title:

Role of soil seed bank in pattern of species distribution along the aridity gradient by using the technique of multivariate analysis

Author (s): Allah Bakhsh Gulshan, Altaf Ahmad Dasti Seema Mahmood, Sabir Hussain and Imran Atta
Abstract:

Floristic composition and diversity of weed infestation depend at least in part on the soil seed bank in agro-ecosystems. The results in this investigation of soil seed bank, total 1269 seedlings from 34 species emerged from the 180 soil samples cores of varying depths ranges from 0-30cm. The application of the classification to ordination suggested that up ground weed vegetation depends under the preservation of soil seed bank and some extent to crop specific. This study provides a protocol that both classification and ordination are able to delimit the seed bank of weed communities according to their habitats. Such analysis should improve the way complex data analysis and patterns are interpreted. The distribution pattern of the species along the DCA axes 1 and 2 showed a very complex pattern and is hardly interpreted. However, on the first axis, species communities in rain fed form lands, such as Aerua persica, Calotropis procera, Citrullus colocynthes and Heliotropium strigossum are clustered at lower score end of DCA axis. High score end is occupied by the species occur in canal fid fields. On the second axis, species like Conyza bonariensis, Phyla nodiflora, and Polygonum plebejum (belong to association D) have high value than those that occur in Indus valley (association B).

Sirous Bidarigh and Ebrahim Azarpour

Abstract:

Tea [Camellia sinensis (L.)] is one of the most important beverage crops in the Iran. There has been a steady demand for production and supply of cuttings of different varieties for tea gardens in Iran. In order to study the effects of MS medium levels (full MS, half MS and redundancy MS) with 1mg/L indole-3-butyric acid (IBA) hormone on rooting in micro cuttings of tea, an experiment as RCBD with four replications was conducted during 2010 at Research Laboratory of Faculty of Agriculture, Lahijan University in Iran. The culture bed were contained MS levels (full MS, half MS and redundancy MS), 1mg/L IBA hormone, sucrose (3%) and agar (75%). The results show that MS medium levels with IBA hormone on root length and root number in micro cuttings of tea had a significant difference in 1 % probability level. The highest root length (17.22 mm) and root number (4.93) in micro cuttings of tea were obtained with application redundancy MS medium (25% macro element) and 1mg/L IBA. The lowest root length (3.17 mm) and root number (0.68) in micro cuttings of tea were obtained with application full MS medium (25% macro element) and 1mg/L IBA.

Author (s): Ahmad S. Muhaimeed, S. N. Aziz and I M. Amin
Abstract:

Two study sites were selected in Northern Iraq under different climatic conditions. The first site Located in Ibraheemawa city-Al Sulaemini Governotrate lies within Zagroz mountain physiographic unit, in folds zone formed from limestone during Miocene period. The climate of this region is sub humid with mean annual rain fall, more than 1300 mm/year and mean annual temperature 18.7C. The second site located in Saleemawa city at Dalia Governa tore lies within foot hill physiographic unit formed from lime stone parent rock during the Miocene period and under semiarid climatic conditions with mean annual rain fall 360 mm/year and mean annual temperature 24.3C. Two pedons within each site were exposed and described and sampled for laboratory analysis. The results of morphological, physical and chemical properties of the studied pedons indicated Some differences between soils of the two regions due mainly to the effect of climatic conditions and the nature of parent material studied soils show some variation in the amount and distribution pattern of soil components with depth. Soils pedons in Ibraheemawa show a greater degree of soil development reflected by thick mollic epipedod with thick Argillic horizons, lower content of calcium carbonate, soluble salts with high conent of total clay, fine clay and silt. The studied soils were classified as Mollisols and Aridisols in the two regions respectively.

Title:

Increasing irrigation efficiency by management strategies: cutback and surge irrigation

Author (s):

Mohammad Valipour

Abstract:

Increasing irrigation efficiency always has been one of the main concerns of experts and farmers. In previous researches, many methods have been proposed to achieve this purpose. But in surface irrigation farmers often received themselves required water in specified time (cutoff time) and the limited amount (input discharge). Thus, not all methods that increase irrigation efficiency are applicable. If the cutoff time to be constant only input discharge is a parameter that by reducing it using management practices farmers are able to increase irrigation efficiency. In this study, using different types of inflow regimes include continuous flow, cutback, fixed surge, and variable surge, increasing irrigation efficiency examined in border irrigation. Obtained results from performed simulation using SIRMOD software showed that cutback and surge irrigation methods were able to increasing irrigation efficiency to the amount of 11.66% and 28.37%, respectively. Farmers according to the limitation of inflow regime choice can identify the best amount of input discharge to achieve maximum of irrigation efficiency.

Title: The productive performance of local chickens in three ecological zones of Ghana
Author (s): J.K Hagan, M Bosompem and Akpor I

Abstract:

A survey was carried out in three agro-ecological zones (coastal savannah, rain forest and guinea savannah) of Ghana to find out the productive performance of local chickens. A total of 180 local chicken keepers (60 each from the three zones) were randomly selected with the help of the Agricultural Extension Agents in the zones. Data were collected through the administration of pre-tested semi-structured questionnaires, direct observations and measurements of productivity indices. Data collected included clutch sizes, number of clutches per year, egg production per year with and without hatching, age at sexual maturity, flock size and composition, hatchability and chick survival rates. Egg and body weights of birds were measured. Results obtained showed an average flock size per household of 17.5, 24.3 and 11.7 for the coastal, forest and savannah zones respectively, with an estimated inbreeding coefficient of 0.04. The mean clutch number was 3.0 with a clutch size of 12.8 eggs. The local birds were found to reach sexual maturity at 5.7 and 6.4 months for cocks and hens respectively. The annual egg production with hatching was 38 eggs with an egg size of 41.3g and 84.5% hatchability rate. The birds were found to be reared under the traditional extensive system with little or no care. Diseases (Newcastle), predation and theft were found to be the main causes of loss of bird or reduction in flock size. It is advocated that extra effort in the management and improvement of local chickens in the areas of housing, breeding, feeding and health care can go a long way to improve the productive performance of local chickens in Ghana.

Author (s):

M. A. Agbaje, F. Y. Okunmadewa, B. T. Omomona and O. A. Oni

Abstract:

Poverty is a serious challenge in Nigeria especially in the rural area and it has been intractable because policies and programmes in the country are based on static poverty analysis. For effectiveness of policies and programmes on poverty, a forward looking approach-vulnerability to poverty, should be adopted, hence this study. This study investigated the vulnerability to poverty across in rural Nigeria, using the 2004 NLSS data. The result of the 3-Stage Feasible Generalized Least Squares showed that at the standard vulnerability threshold of 0.5, 62.2% of rural households were vulnerable to poverty. Vulnerability to poverty was higher in northern zones and lower in the southern zones. Male headed households (59.8%) were more vulnerable to poverty than their female counterpart (43.9%). For every 100 households that were poor, 12 more will be poor in future in south, 11 more in households with heads without formal education, 8 more in farming households and 6 more in male headed households. Consumption variance index was consistently higher among non-farming households (0.0301), female headed households (0.0403) and those with primary education (0.0327). Mean consumption index was lower among farming households (0.0274), male headed households (0.0274), those with no formal education (0.0237) and those with household size greater than 20 (0.0168).

Abstract:

To find out the comparative efficacy of herbicides on yield and yield components of wheat (triticum aestivum L.) an experiment was conducted at Cereal Crops Research Institute (CCRI) Pirsabak, Nowhshera during the winter season 2006-07. The experiment was comprised of 6 herbicides plus hand weeding and weedy check plots. The herbicidal treatments were the post-emergence application of Affinity 50 WDG (carnfentrazone ethyl + isoproturon) @ 0.016, Buctril super (bromoxynil octanovate + heptanovate ester) @ 1.23, Puma super 75 EW (fenoxaprop-p-ethyl) @ 0.94, Topik 15 WP (clodinafop propargyl) @ 0.04, Topik 15 WP + Buctril super 60 EC (fenoxaprop-p-ethyl+ bromoxynil octanovate + heptanovate ester) @ 0.04 +1.23, Puma super 75 EW + Buctril super 60 EC (fenoxaprop-p-ethyl + bromoxynil octanovate + heptanovate ester) @ 0.94 + 1.23 kg a.i ha-1, while hand weeding was performed three times in the respective treatments. The data were recorded on weed density m-2 30 days after treatment, number of tillers plant-1, number of grains spike-1, 1000 grain weight (g), biological yield (t ha-1) and grain yield (t ha-1). For effective weeds controlling Affinity 50 WDG proved to be the best treatment with minimum weed density after treatment 33 weeds m-2 was observed in plots treated with Affinity 50 WDG while; maximum weed densities were recorded in weedy check plot with 117 weeds m-2. Similarly the maximum grain yield of 4.072 t ha-1 was recorded in Affinity plot followed by hand weeding plot and the plot sprayed with the mixture of Buctril super + Puma super with grain yield of 3.773 t ha-1 and 3.483 t ha-1 respectively. A minimum grain yield of 1.603 t ha-1 was recorded in weedy check plots. Affinity was also proved to be effective in other parameters like spikes m-2 (484), number of grains spike-1 (52) and 1000 grain weight (36 g). In the light of this study the herbicide Affinity 50WDG followed by the mixture of Buctril super + Puma super provided better results for the control of weeds in the wheat crop.

Author (s): Seyyed Mustafa Sadeghi and Seyyed Ali Noorhosseini Niyaki
Abstract:

In order to study the effect planting date and cultivar on yield and yield components of soybean, an experiment was conducted for two seasons (2009-2010) at kateshal research station, Lahijan, northern Iran. Three cultivars, Hill, Sahar and Zan were sown on four sowing dates of Apr 20, Apr 30, May 10 and May 20 during the two consecutive crop seasons. The design was a split-plot replicated three times with sowing date as main plots and cultivar as sub-plots. Data were collected on number of pods per plant, seeds number of main stem pods, pod length, maturity period duration, oil percent, protein percent, 1000- seed weight and seed yield. Mean comparison had been done by Duncan’s test that showed there were significant differences among means of traits at different planting date treatments. Also, there were significant differences among interaction of date of planting and cultivars for all traits at 1% level. The data were analyzed statistically, which showed that the cultivars with early sowing produced gave higher yield and quality as compared to the late sowing date. The results revealed that higher numbers of pods per plant and seeds number of main stem pods were produced by April 30 and Sahar cultivar. Similarly maximum seed yield (4176.09kg ha-1 and 3219.96 kg ha-1) were produced by Apr 20, Sahar and Apr 30, Sahar, respectively.

Title: Urban agriculture livelihoods and household food security: a case of Eldoret, Kenya
Author (s): Mugalavai Violet Kadenyeka, David Omutimba and Nyakecho Harriet
Abstract:

One of the aims of the MDGs is to halve the world’s poor population with an income of less than one dollar a day as well as those who suffer from hunger (Mougeot, 2005). By 2015-2020, more than half of the world’s population will be living in urban and peri-urban areas. One common livelihood that the poor venture into is Urban Agriculture (UA) which involves the production, processing and selling of livestock, poultry and horticultural produce and products due to the immediate monetary gains and the necessity for a quick source of food. The main objective of this study was to determine the socio-economic characteristics of low-income horticultural food producers and sellers (HFPS) and how this affects their livelihoods and household food security. An exploratory survey design was used to examine the diverse manifestations brought by the interface between the livelihoods of HFPS. The study integrated the livelihood framework to examine the respondents’ socio-economic characteristics and the resultant food security status of their households. Non-probability sampling was used to get 110 producers and 110 sellers. The study used both quantitative and qualitative research methods. Quantitative data was analyzed using SPSS (15.0) software whereas qualitative data was triangulated into the discussions of the quantitative findings. The results revealed that the current infrastructure is not conducive for sustainable UA practices, which affects the interactive livelihoods and household food security of HFPS. A synergy of stakeholders should to engage in serious working partnerships in developing sustainable and contextual pro-poor infrastructure for enhanced UA livelihoods, in order to stimulate growth and increase efficiency, productivity, employment and generate better returns for the poor.
