Analysis of maize production and supply for food security improvement in the Borgou region in Northeast of Benin

  The analysis of maize production and supply in Borgou region was conducted using data collected from 186 producers of maize. The analysis was done by commonly using means comparison tests and a multiple regression model. It comes out from this analysis that only 20.44% of the production is self-consumed, against 79.56% supplied on the market. Also, when the maize cultivated areas increase by 1%, its supply...

Comparison of two types of improved tropical maize populations in Benin

  Two types of improved tropical maize populations, ABY1 (an improved traditional population) and DMRESRW (an elite introduced improved population) were compared for important agronomic traits during 2 years in South Benin (tropical lowland zone) in two locations corresponding to two different types of growing conditions: Abomey-Calavi (favourable conditions) and Abomey (unfavourable conditions). A randomized...

Random amplified polymorphic DNA (RAPD) polymorphism in Puccinia sorghi Schw. causing common rust of maize

  An experiment was conducted at University of Agricultural Sciences, Dharwad, Karnataka to detect molecular variation in Puccinia sorghi Schw. through molecular tool viz., random amplified Polymorphic DNA (RAPD). In this study, molecular variation in the pathogen served as a guideline for breeding suitable maize varieties against common rust disease which seriously affects maize productivity. It...

The role of rural producer organizations in enhancing market participation of smallholder farmers in Uganda: Enabling and disabling factors

  The study investigates the factors influencing the effectiveness of second-tier rural producer organizations (RPOs) in linking their members to output markets in Uganda. The percentage of farmers who sold some of their produce through the RPO was used as a proxy for effectiveness. Ordinary least squares (OLS) regression analysis indicated that RPO effectiveness was positively related to the size of a RPO and...

Insecticide effect of wild plant powders on bean weevil (Zabrotes subfasciatus Boheman; Coleoptera: Bruchidae) in vitro

  The loss of stored grain is one of the most common problems faced by small farmers. The major pest of stored bean is the bean weevil (Zabrotes subfasciatus) as it can lead to total loss if left uncontrolled. The insecticide effect of 13 plant powders obtained from 11 different plant species was evaluated under laboratory conditions. The effect was assessed in terms of mortality, emergence of...

Insecticide irritability of plant extracts against Sitophilus zeamais

  Several plant species were selected as potentially safer substitutes for control of maize weevil, Sitophilus zeamais Motsch. The objective of the study was to investigate the insecticide irritability effect (that is, avoidance after contact) of ethanol extracts (0.05 gm.L-1) of the species Croton heliotropiifolius (leaves and flowers), Duguetia...

Prediction of adaptability and yield stability of elite grain amaranth genotypes under different population densities (Amaranthus hypochondriacus L.)

  The study was conducted to assess the yield stability across the plant densities. Amaranth genotypes were evaluated for yield characters under very high (D1), high (D2), normal (D3) and low (D4) plant density levels to determine stability parameters. The study was conducted at Karaikal, Puduchery, India during November, 2007 to February, 2008. The results revealed that genotype Annapurna was stable for...

Genetic control of zinc and iron concentration in common bean seeds

  The objective of this study was to obtain information regarding genetic control of zinc and iron levels in common bean seeds. For that purpose, four lines with high iron and zinc concentration and four with low concentration were crossed in a partial diallel design. Hybridizations were carried out in a greenhouse, as well as obtaining F1, reciprocal F1 and F2 generations. The data obtained were...

Effect of soil fertility on the establishment of improved grass and legume species grown in fallows in Chivi district, Zimbabwe

  A pot experiment was conducted to investigate the effect of soil fertility on the establishment of two improved grasses (Pennisetum purpureum and Cynodon nlemfluensis) and two legumes (Desmodium uncinatum andNeonotonia wightii) in soils collected from different fallow periods [0 to 2, 3 to 5, 6 to 10, 11 to 20 years and uncultivated field (control)] in Chivi district in south central Zimbabwe....
