N Wheat (Triticum astevium) production in Kenya has been severely affected by stem rust Ug99 and its related race groups. The consequence of not controlling this disease is steep decline in the crop production thus creating food insecurity to over 70% of the small-scale holder farmers who depend on it as a source of food as well as income.

The causative agent of the disease Puccinia graminis f. sp tritici (Pgt) has been studied by researchers globally because of its rapid evolution of races within lineage overcoming existing resistant genes. Understanding the population structure will highlight the predominant race(s) as well as their geographical distribution. This information is required to enable breeding for resistant wheat varieties. The objective of this study was to characterize the population structure of Puccinia graminis f. sp tritici population in 2015. Using 10pgt Simple Sequence Repeats (SSR) markers 104 single uredenial-pustule samples were analysed. Minimum spanning network pattern was composed of five Simple Sequence Repeats multi-locus genotypes (SSR-MLGs) that were organized around three nodes based on samples chosen from wheat growing fields with the reference isolates; races TTKSK and TKTTF. In addition to this, non-parametric DAPC analysis showed the presence of single population made up of two predominant races from clade I (Ug99 race group) and clade IV-B (race TKTTF/TTTTF). Analysis of molecular variance (AMOVA) according to Bayesian Information Criterion showed clustering was majorly based within populations (0.576%) rather than among clusters (0.441%).

As a preliminary study that sets ground for the introduction of new leguminous vegetables, this survey assessed the state of production and market characteristics of leguminous vegetables in urban and peri-urban areas of southern Benin.

Covering three administrative departments where most vegetable growers and traders are based in Benin, the study used the semi-structured interview approach with 105 respondents including vegetable growers and traders to gather information on diversity, pest and disease management practices, constraints, distribution channel of leguminous vegetable cultivated and willingness to adopt new leguminous vegetable species and varieties. The results showed clear task division between males and females. While a narrow diversity of leguminous vegetable species was grown in Benin, their production is highly market driven. Tunnel type greenhouse and open field farming were practiced in mono-cropping or crop rotation system with the use of poultry manure, animal dungs and mineral fertilizers as mean of fertilisation. The collectors and wholesalers were the most important stakeholders of the distribution channel, followed by the hotels and restaurants. Major constraints include pest and disease infestations, low yield achieved and lack of improved varieties. All respondents were willing to adopt new leguminous vegetable including vegetable soybean "edamame", peas, pigeon peas, mung bean, faba-beans, common bean. This study provides insights to the current situation and prospects of the legume vegetables sector in Benin, and can be used as decision tool for the introduction of new leguminous vegetable species to promote the sector and make substantial contribution to nutritional security in Benin.

Common bean is the most important pulse crop in Kenya, though small scale farmers have limited access to pest resistant seeds. This has therefore made common bean yields remain below 1000kgha^-1, while the potential is 2000kgha^-1. However phenolics are secondary metabolites present in plants and this could be an attribute contributing to common beans resistance to bean fly infestation.

The objective of this study was to devise effective ways of managing bean fly by use of phenolic content present in commercial varieties of common beans. This was achieved by determining the total phenol content of the beans. The bean varieties were; KK 8, Tasha, KK 15 (Resistant check), Chelalang, Wairimu dwarf, Ciankui, GLP 585, Miezi mbili, GLP 2 (Susceptible check), GLP 1004, GLP 24, and GLP 1127. Experimental design was RCBD with three replications. Data collected were subjected to ANOVA, mean values were separated using LSD at 5% level of significance. Chelalang, Tasha, GLP 1004, KK 8, GLP 585 and KK 15 showed resistance and high yields. Phenol content was significant (P< 0.05) in resistant common bean varieties (KK8, Tasha, Chelalang, GLP 585, KK15, and GLP 1004). The common beans which showed significant resistance to bean fly had significant (P< 0.05) high yields of above 1000Kgha^-1.

Therefore from the study it was evident that presence of phenol content in common beans deters bean fly infestation. Get the full articles via original publisher source at- Int. J. Agron. Agri. Res. 14(3), 9-13, March 2019.

Effects of inorganic nutrient P and N application on Azolla biomass growth and nutrient uptake | IJAAR

 By: WA Oyange, GN Chemining’wa, JI Kanya, PN Njiruh

"" IJAAR welcome all of you to submit your research paper for publication in the field of Agriculture, Agronomy, Horticulture etc. Please submit your manuscripts via Online submission panel.""

Rice farmers in Mwea Irrigation Scheme routinely apply P and N fertilizers which affect water nutrient levels. A study was conducted to establish the effects of nutrient N and P application on Azolla biomass accumulation. The study was conducted in a batch culture experiment, using 5g of fresh Azolla biomass samples from each of the six major paddy schemes namely: Mwea, Ahero, West Kano, Bunyala, TARDA, and Taveta.

Treatments consisted of 0 and 3mg P l^-1 and 0 and 200mg N l^-1, laid out in a randomized complete block design replicated three times.  Azolla samples were grown in batch culture plastic pots of 8.4 x 10^-3m³ for 10 days using canal water, which was replenished every three days. Fresh Azolla biomass weight was recorded at 0, 5 and 10 days after inoculation. Data was subjected to analysis of variance using SAS statistical package version 9.1 and means separated using the least significant difference test (p≤0.05). The pH levels in irrigation water averaged 7.2 while N, P and K levels were 20.2, 11.6 and 15ppm respectively. Tissue N and K for Azolla accession averaged 4.2% and 1.6% respectively. Biomass accumulation and doubling time of Azolla were significantly affected by exogenous P and N nutrient application. Doubling time ranged from 5.5 days to 6.7. Application N and P significantly reduced Azolla biomass accumulation and increased biomass doubling time.

 

Introduction

Azolla is a pteridophyte which forms a symbiotic association with a cyanobacterium-Anabaena azollae (Bocchi et al., 2010) and fixes nitrogen at a rate higher than legumes (Wagner, 1997). A study on Azolla has reported that Azolla contains 4.5% N, 0.4% P and 1.5- 3% K (Watanabe, 1989). In Mwea Irrigation Scheme, the existing species was found to contain 3.9% N, 0.44% P, and 1.08% K (unpublished). Azolla is capable of providing 40kg N ha-1 to the rice crop due to its nitrogen content which is released upon decomposition (Kannaiyan et al., 1982) reported that. This can reduce the cost of rice crop inorganic fertilizer, which constitutes 20% of rice production cost in Mwea Irrigation Scheme (Rice MAPP, 2012). In Mwea Irrigation Scheme, Azolla coverage is estimated at 30-50% during peak times and this is majorly dependent upon water availability (unpublished). Nutrient status and other environmental factors are major factors affecting Azolla biomass growth (Wagner, 1997). 

Extensive and intensive inorganic fertilizer use forms the primary source of the water nutrient status and eutrophication in water bodies (FAO/ECE, 1991). Depending on the levels, this can cause atmospheric, aquatic and ground water system pollution (Choudhury et al., 2005). Farmers in Mwea irrigation scheme apply estimated P and N fertilizer amounts of 58kg of P2O5 and 56kg of N per hectare respectively, based on recommendations by Wanjogu et al. (1997). These fertilizers applied contribute to the water nutrient status being conducive for Azolla growth. The nitrogen fixing ability of Azolla makes it able to grow in nitrogen deficient waters (Watanabe, 1979; Hussner, 2010). However, its growth is limited by the nutrient element P (Kitoh et al., 1993). Kondo et al. (1989) reported a maximum growth rate for Azolla under application of 3.1ppm P with a threshold limit of 0.5-0.6% P. 

The level of phosphorus in water bodies is varied and can be high due to fertilizer use and runoff. This can lead to Azolla blooms in paddies or flood waters. Depending on the water nutrient status, Azolla multiplies fast; doubling its biomass in less than 10 days and readily colonizes new areas (Campbell, 2011). Hussner (2010) reported a doubling rate of 3-10 days, while Kitoh (1993) reported a doubling rate of 2-3 days under laboratory conditions. The nutrient P is important for Azolla growth and reproduction (Sadeghi, 2012). Its deficiency has been shown to hinder the acetylene reduction activity (Tung et al., 1989). However, excess levels of nutrient P has been reported to have a negative effect on Azolla growth (Pitt et al., 2014). 

According to Rains et al. (1979), a P level of 0.34ppm is the lower threshold limit below which there is deficiency. Subudhi et al., (1981) reported that external P level of 5ppm is the higher threshold limit beyond which Azolla tissue N content is affected negatively. The nutrient N is important for Azolla growth but because of its N fixing ability, it is capable of growing in N free media (Hussner, 2010). External N has been shown to inhibit the activity of acetylene reductase activity (Yatazawa et al., 1980). Kitoh, 1991 showed that external ammonia N negatively affects Azolla growth and N fixation activity. The objective of this study was to determine the effects of P and N on Azolla biomass growth and tissue N and P uptake, in Mwea Irrigation Scheme. Get the full articles and pdf at: Int. J. Agron.

A field survey was conducted in Algeria to assess the state of dieback in some vineyards and identification the fungal pathogens associated with necrotic wood lesions. Field surveys conducted during spring seasons in 2006 and 2012 revealed that an average disease incidience was 25 % , the indice of disease severity varied of 0.5-2%, based on herbaceous symptoms.

Some sections of wood cultivar, collected from four localities vine showed many kinds of necrosis, central sectoral(brown colour), necrosis sectoral(grey colour) and central light brown. Wood samples were collected and used for isolation and then placed on potato-dextrose (PDA) medium. The results showed that the presence of wood fungi mostly affected the vine trunk were isolated and the fungi were identified morphologically as Botryosphaeria species and Fomitiporia mediterranea.

The study was aimed at evaluating the proximate composition of groundnuts cultivated using Yaralegume and Humate Green OK fertilizers at four (4) communities in the Lambussie-Karni District of the Upper West Region of Ghana. In all, twenty four (24) fresh and stored groundnut samples were analysed using standard methods and procedures.

The results indicated average moisture, crude protein, crude fat, crude fibre, ash and carbohydrate contents of 3.65 %, 24.78 %, 44.70 %, 5.65 %, 2.18 % and 19.16 % for fresh groundnuts and 3.88 %, 27.08 %, 47.62 %, 6.76 %, 2.28 % and 12.28 % for stored groundnuts respectively. After storage, 83.33 %, 58.33 % and 66.67 % of the samples recorded increase in moisture and crude protein, fibre and ash content, and crude fat correspondingly. However, 91.67 % of the samples had reduced levels of carbohydrate after storage. Fertilization did not have a significant impact on the proximate composition of both categories of groundnuts and therefore, the use of these fertilizers to improve the proximate composition of groundnuts may not be recommendable but storage could improve proximate composition.

Morphological and genetic variation in Aegilops geniculata Roth. from Tunisia - IJAAR

• Khaled Mguis1,2†, Asma Mahjoub3†, Mejda Abassi2 , Ali Albouchi2 , Zeineb Ouerghi1, Ben Brahim Nadia3 , Zoubeir Béjaoui2

Aegilops geniculata Roth is an annual grass relative to cultivated wheats and is widely distributed in North Africa. In order to understand the diversity of this species, 13 populations collected in different bioclimatic areas in north and central Tunisian were analyzed using morphological and molecular characters.

Principal component analyses (PCA) based on the agro- morphological characters allowed the separation of populations in five mainly bioclimatic groups characterized by different morphological patterns. Populations originated from humid coastal areas were characterized by good vegetative development, vigorous spikes and caryopses. Samples collected from mean altitude with sub-humid climate had late germination and a large growing cycle a high biomass production and weak caryopses. Populations collected from intermediate and high mountains with sub-humid and semi-arid conditions presented good fertility and high yield-related. Individuals with early germination, weak vegetative development and high caryopses yield characteristics of the coastal areas and plains in sub-humid and the upper semi-arid climate. Populations originated from steppic highlands in upper arid conditions and mean and high altitudes mountains with upper semi-arid were characterized by low morphological development, weak fertility reduction of yield-related and shortening of growing cycle.

Individuals were distinguished successively by Phenological, morphological and Yield-related traits. RAPD analysis based on the phenotypic variability and genetic distances revealed a significant variation within and between populations associated with bioclimatic conditions, in particular winter temperature. Genetic diversity was higher in populations growing under warm bioclimates than in those from cold bioclimates.

Response of maize (Zea mays L.) to sodium chloride concentrations at early growth stages - IJAAR

• Y. Abdellatif Idris*, Siddig A.M. Ali

• Department of Agronomy, Faculty of Agriculture, University of Zalingei, Sudan

The present study was conducted to investigate the effect of NaCl concentrations on seed germination and seedling growth of maize (Zea mays L.). Laboratory and pot experiments were conducted in 2014 using maize seeds obtained from Ministry of Agriculture Central Darfur State, Sudan. Ten seeds were germinated in Petri dishes containing filter paper of 9cm diameter, whereas in the pot experiment, five healthy seeds were allowed to germinate in plastic pots containing loamy soil.

Treatments comprised of control (distilled water), 0.5%, 1.0%, 1.5% and 2% of sodium chloride (Na Cl). Treatments were arranged in completely randomized design (CRD) with 4 replications. Data recorded for the both experiments were subjected to analysis of variance (ANOVA). Least Significant Differences (LSD) method was used to test differences between treatments means at 5% and 1% probability levels. Results of the laboratory experiment showed that the number of germinated seeds was significantly affected by salinity level, especially by the higher salt concentration. Final germination percentage and seedling vigor index decreased with increasing salinity level. The highest seed germination percentage (97.5%) and seedling vigor index (2.49) were found with the control (0% NaCl) and the lower seed germination percentage (22.5) and seedling vigor index (0.05) were found with 2% concentration. Results indicated that the plumule length decreased significantly (p ≤ 0.01) as concentration of NaCl increased. The radical length followed the same trend of the plumule length, it was decreased significantly (p ≤ 0.01) as NaCl increased. Results of statistical analysis of pot experiments revealed that salinity made highly significant effects (p ≤ 0.01) for the investigated traits. It was observed that the highest seed germination percentage (95%), seedling vigor index (23.3), plumule length (24.7 cm), radical length (26.2 cm) plumule fresh and dry weights ( 1.95 & 0.24 g/plant ) and radical fresh and dry weights ( 1.66 &0.203 g/plant ) were observed in 0%NaCl (control). No seeds germinated in the 1% and above NaCl treatments.

In order to evaluate the responses of potato genotypes to different irrigation treatments, an experiment was carried out as split-plot based on randomized complete block design with three replications at the Research Center of Ardabil Agricultural and Natural Resources, Ardabil, Iran in 2013. Irrigation treatments were assigned to main plots and three Potato genotypes were allocated to the sub plots. The potato genotypes traits such as tuber yield, relative water content, starch content, chlorophyll (a), chlorophyll (b), chlorophyll (a+b), and carotenoid were assessed under both well-watered and deficit irrigation conditions. Results showed that limited irrigation reduced plant tuber yield to17.7% compared with common cultivar. The Clone 97-2 gave the highest tuber yield, chlorophyll (a+b) and carrotenoid content at 80% irrigation treatment. Therefore, some genotypes of potato are more suited for planting in Ardabil region. It was concluded that using clone 97-2 genotype in this region would be an advantage for farmers.
