“…Acid detergent fiber (ADF) content increased significantly (F= 899.20, p<0.001) as the growth of plant continued and maximum ADF content in all genotypes was observed at 60 DAS (Table 2). Similar results were reported in maize (Firdous and Gilani 1998) and sorghum (Firdous and Gilani 2001). The significant (F= 649.75, p<0.001) decrease in ADF content was observed with N fertilization in fodder oats.…”

A field experiment was conducted to evaluate the yield and quality parameters of oats (Avena sativa L.) at forage research farm in Punjab Agricultural University, Ludhiana. Four different nitrogen levels viz. 0 (control), 50, 75 (recommended) and 100 Kg N/hawere applied in the form of urea. Samples were collected at three different growth stages i.e. 30, 45 and 60 DAS. As the growth of plant continued decrease in total nitrogen (45%), non protein nitrogen (37%), ether extract (13%), ash content (24%) and digestibility (23%) was observed. But increase in free amino acids (48%) and cell wall constituents i.e. ADF (19%), NDF (31%) and CF (34%)with plant's growth was reported. The interactive effect of varying levels of inorganic fertilizer application on the chemical composition of the plant at various growth stages revealed an increase in total nitrogen (18%), non protein nitrogen (26%), ether extract (18%), free amino acids (32%), ash content (13%) and digestibility (7%) with increase in fertilizer level however ADF (7%), NDF (2%) and CF (3%)content decreased with increased levels of nitrogen fertilization.Correlation studies showed that significant negative correlation was present forin vitro dry matter digestibility with acid detergent fiber (r= -.861**), neutral detergent fiber (r= -.891**) and crude fiber (r= -.740**) at recommended dose of N fertilization. The objective of this study was to investigate the effect of different doses of nitrogen fertilization at different growth stages on quality components in oats fodder.

Techno-Economic Analysis of a Cogeneration System for Post-Harvest Loss Reduction: A Case Study in Sub-Saharan Rural Community

Over 90% of global yam production is from West Africa where it provides food and income for above 300 million smallholders’ farmers. However, the major challenge of yam is 10–40% post-harvest losses due to the lack of appropriate storage facilities. This paper assesses a biogas-driven cogeneration system, which could supply electricity and cold storage for ‘yam bank’ within a rural community. Considering 200 households’ Nigerian village as a case study, crop residues are used as anaerobic digestion feedstock to produce biogas, which is subsequently used to power an internal combustion engine. Result shows that the system could store 3.6 tonnes of yam tubers each year and provide enough electricity for domestic and commercial activities. At the current electricity tariff of USD0.013·kWh−1 for rural areas, the system is unable to payback during its life span. The proposed USD0.42·kWh−1 by Nigerian Rural Electrification Agency seems good with less than 3 years discounted payback period but brings about extra burden on poor rural households. Based on the income from cold storage, electricity tariff of USD0.105·kWh−1 with an interest rate of 4% is suggested to be reasonable which results in 6.84 years discounted payback period especially considering non-monetary benefits of renewable energy system.

“…The higher percentage of infestation obtained in all the accessions examined in screen house could be attributed to the age and soft nature of their tissue for easy feeding tunneling. In line with this assertion, morphological factors such as leaf fibre, surface wax, silica and high hemicelluloses have been reported to influence the nature and texture of any plant and increases with the plant age (Firdous and Gilani, 2001). These factors have been identified as resistance mechanisms against stem borers (Bergvinson et al, 1995).…”

Evaluation of pearl millet (Pennisetum glaucum L. (R. Br.)) landraces for resistance to stem borer (Coniesta ignefusalis Hampson.) infestation

Characterisation of germplasm collection is imperative for identification and selection of new resistance sources in any crop breeding programmes. Thus, evaluation of pearl millet germplasm for resistance to stem borer infestation was carried out in view of the challenges of poor yield and quality reduction of pearl millet, elicited by its feeding activities. Thirty-five (35) pearl millet accessions were collected from different states where the crop is majorly cultivated in Nigeria. The accessions were characterised for resistance to stem borer infestation on the field. Further confirmation for selected potentially resistant accessions under artificial screen house conditions was done using a randomised complete block design (RCBD) with ten replications each. The field estimated selection index showed that out of the 35 accessions screened, 15 accessions were potentially resistant; 13 resistants with range value of 0.00 to 0.40 and 2 moderately resistant. Further nursery screening confirmed 9 of the 15 accessions to be resistant under artificial infestation. NS-JIL-01 accession was most highly resistant with significant least leaf damage score of 0.25. Significant and positive correlation (r = 0.32) was obtained between days to anthesis and number of larvae per plant at p < 0.01. Negative correlation of percentage internodes damage with panicle diameter (-0.26) and panicle weight (-0.25 gn) at p < 0.01 as well as weight of 1000 seeds (r = -0.19, p < 0.05) were also significant. The identification of potentially resistant accessions on field and confirmation of some of the accessions under artificial screen house conditions indicated, gene for resistance to stem borer infestation in pearl millet could be obtained from the natural eco-type germplasm.
