A total of nine species of fungi were found to be associated with seeds of nine varieties of chickpea. The isolated fungi were Alternaria alternata, Aspergillus flavus, A. niger, A. fumigatus, A. nidulans, Curvularia lunata, Penicillium sp., Rhizopus stolonifer and Trichoderma viride. Association of fungi with chickpea seeds was recorded three times, within a week after harvest, after two and five months of storage. The fungal association varied with duration of storage period. Species of Aspergillus, Penicillium and Rhizopus become predominating fungi with increase of the storage period. The fungal association with seeds of chickpea also affects germination, seedling mortality and seedling height. Germination of BARI chola 6 and 7 were completely inhibited due to prevalence of Rhizopus stolonifer in the seeds examined within seven days of harvest. The total fungal infection in chickpea seeds was highest in BARI chola 8 (168) and lowest in BARI chola 1 (65).Journal of Bangladesh Academy of Sciences, Vol. 40, No. 1, 37-44, 2016

The experiment was conducted at the research field of Regional Agricultural Research Station, Jessore during two consecutive rabi seasons of 2008-2009 and 2009-2010 to find out the effect of hydropriming on the performance of maize seeds under variable soil moisture regimes. The treatments of the experiment were two priming methods viz., i) Hydropriming, ii) Non-priming and four moisture regimes viz., i) Wet condition, ii) Field capacity, iii) 75% of field capacity, and iv) 50% of field capacity. Results showed that yield and yield contributing characters (plant population/m2, number of cobs/m2, length of cob, diameter of cob, 100-grain weight) were influenced significantly by hydropriming. Yield and yield contributing characters were highest when hydroprimed seeds were sown at field capacity whereas it was the lowest at 75% of field capacity from non- primed seeds. Days to tasseling, days to silking, and days to maturity were reduced when hydroprimed seeds were sown at field capacity. At 50% of field capacity, no germination was occurred.

Abstract Quality Protein Maize (Zea mays L.) (QPM) varieties have been developed by scientists at the Institute of Agricultural Research and Training in Nigeria. For these varieties to have significant impact, they must possess traits acceptable to farmers. A study was carried out to evaluate the agronomic and sensory traits of two Quality Protein Maize - ART-98-SW-6-OB (QPM1) and ILE-1-OB (QPM2), in comparison with ART-96-SW-1 (High Protein Maize) and SUWAN-1-SR (a popularly grown improved variety) in three maize growing communities of South West, Nigeria. Sixty (60) farmers comprising males and females were evaluated for six sensory parameters. The parameters tested were appearance, colour, flavour, texture, taste and overall acceptability. The results of the agronomic evaluation showed that there were no significant differences in the height of QPM varieties and HPM at harvest. QPM varieties gave the highest grain yield of 2.38t/ha for ART-98-SW-6OB and 2.36t/ha for ILE-1-OB. Sensory evaluation showed that when the maize varieties were processed into corn-soy milk, QPM corn-soy milk had the highest sensory scores for all sensory parameters tested. Quality Protein Maize varieties had high grain yield and were most preferred for maize pudding and corn - soy milk. The QPM varieties, if formulated into foods for household or commercial purposes, should have good chance of being accepted by farmers with continuous promotional campaigns.

The field trial was carried out to evaluate the effect of timing nitrogen second dose fertilization on the grain yield and yield components of some improved maize varieties. The field experiments was conducted at the Institute for Agricultural Research IAR-ABU Research Farm Samaru – Zaria and Military Cantonment Farm Jaji – Nigeria. Treatments consist of three maize varieties (SAMMAZ 14, SAMMAZ 15 and SAMMAZ 16) and six timings of nitrogen second dose of fertilizer application. Data were recorded on grain yield, number of cobs /plant, number of grain /row, cob(ear) diameter, cob(ear) weight and 100 grain weight. Treatments were laid out in a randomized complete block design (RCBD) with three replications. SAMMAZ 16 produced significantly higher grain yield and recorded superior yield characters over SAMMAZ 14 and 15. The results further showed that time of nitrogen second dose application 6 WAS outperformed other timings evaluated at both location. The study identified. SAMMAZ 16 and time 6 WAS appeared to be the option for increased maize grain yield in the study area

Laboratory tests were carried out to investigate inherent quality differences among stored seeds of early, intermediate and late-maturing quality protein maize using completely randomized design (CRD) with three replications at the Seed Testing Laboratory of the Institute of Agricultural Research and Training, Obafemi Awolowo University, Moor Plantation, Ibadan, Nigeria for two consecutive years (2014 and 2015). From the results, germination and accelerated ageing germination traits were affected by the storage period. Similarly, the seed performance on germination, accelerated ageing and the conductivity test were seen to be better in early-maturing than in other maturing maize genotypes. The speed of germination measured as the germination index was low; ranging from 3.24-3.68 days after sowing (DAS) irrespective of the maturity group. Seedling traits measured after physiological quality tests were equally affected by the storage period and the maturity group. All the seedling traits measured were better in the early-maturing genotypes. Seed quality measured by laboratory quality assessments showed that genotypes in the early-maturing group are of high quality. Seeds of early-maturing genotypes retained significantly higher physical and physiological quality parameters and appear to have inherent potential to withstand effects of deterioration due to their slower rate of quality decline.

Micheli ex L., Penicillium sp.1 and sp.2 Link, Rhizoctonia solani Khun., Rhizopus stolonifer (Ehrenb.) Vuill., Rhizomucor Lucet & Costantin, Syncephalastrum racemosum Cohn and Trichoderma viride Pers. The association of fungi with cotton seeds was recorded within two months of harvest, after 6 and 10 months of storage. The association of fungi varied with duration of storage periods. Aspergillus flavus, A. fumigatus, A. niger, Chaetomium globosum, Penicillium sp.1 and Rhizopus stolonifer were found in all the examined varieties. These were the most predominant fungi in terms of prevalence with the increase of storage periods. The fungal association with the seeds of cotton also affected the germination, seedling mortality, height and vigor. The total association of fungi in cotton seeds was the highest in cotton variety CB10 (204) and the lowest in CB8 (71). On the other hand, the total fungal association of Rhizopus stolonifer was the highest (337) and Colletotrichum gossypii was the lowest (1). J. Biodivers. Conserv. Bioresour.
