The rice-wheat system is labour, water and energy intensive and is becoming less economical due to depleting natural resources. The novel constraints of soil health deterioration, weed shift and climate change further aggravate the problem. As an agrarian state in North-western plains of India, Punjab includes a substantial land area (2.6 million hectares) under the rice-wheat cropping system. On an annual average, 55 million tons of crop residue is generated through this cropping system, of which more than 22 million tons of agri-residue is contributed only from rice (Gupta et al. 2020). Rice straw management has always been challenging. Although, the straw generated by the cultivation of wheat is removed from the combine harvested fields for its utilisation as animal feed. However, more than 80% of rice straw is burnt in the field due to its low economic value and other issues such as labour scarcity, interference with the sowing of

An Assessment of Potential Resources for Biomass Energy in Nigeria

Nigeria is a developing country with an insufficient supply of energy to meet the continuously growing demand. However, there are several biomass resources available within the country. This paper presents a desk review, which investigates the potential resources for biomass energy generation within the country. Energy policies to aid biomass use as an energy source within the country were also reviewed. Biomass resources identified within Nigeria include forest residues, agricultural residues, human and animal wastes, aquatic biomass, and energy crops. However, several of the resources, particularly agricultural residues, have competing uses, such as livestock feed and soil rejuvenation. An estimation of the technical energy potential of the biomass resources revealed that about 2.33 EJ could be generated from the available resources in Nigeria. Agricultural residues have an energy potential of about 1.09 EJ, with cassava, maize, oil palm, plantain, rice, and sorghum being the major contributors. Animal wastes, municipal solid waste, and forest residues have energy potentials of 0.65, 0.11, and 0.05 EJ, respectively. The potentials of wood fuel and charcoal are 0.38 and 0.05 EJ, respectively. The study found that despite the available potential and existing policies, not much has been done in the implementation of large-scale bioenergy within the country. However, there has been laboratory and research-scale investigations. The review suggests that more policies and stronger enforcement will aid bioenergy development within the country. From the review, it has been suggested that the agricultural sector needs to be developed to generate more biomass resources. More research, development, and implementation have to be carried out on biomass resources and bioenergy generation processes. The production of non-edible energy crops in marginal lands should also be considered prime to the development of bioenergy within the country.

“…Cette performance des précédents niébé et arachide serait imputable à leur capacité de fixation de l'azote ce qui a enrichi le sol en cet élément bénéfique pour l'alimentation azotée du riz subséquent. Plusieurs études ont démontré les capacités fixatrices de ces plantes (Toomsan et al, 2000 ;Okonji, et al, 2011). Okonji, et al (2011), indiquent que les légumineuses dans la production de riz sont connues pour améliorer la teneur en éléments nutritifs du sol, ainsi que ses propriétés physiques et chimiques.…”

REMERCIEMENTS Les auteurs traduisent leur gratitude à AfricaRice pour l'appui financier de cette étude. RESUMEL'azote constitue un élément essentiel dans la nutrition minérale du riz. Au Burkina Faso, le riz pluvial entre de plus en plus dans les assolements. Cependant, le rendement du riz pluvial reste largement en deçà du potentiel des variétés. Afin de contribuer à une meilleure connaissance de la nutrition minérale du riz pluvial, un dispositif expérimental en split plot a été mis en place en station de recherche de Farako-Bâ en 2013 et 2014 pour évaluer l'effet des rotations et de la fertilisation azotée sur le rendement. Les résultats montrent que les meilleurs précédents du riz pluvial sont les légumineuses niébé et arachide. Ces deux précédents permettent un gain de rendements respectivement de 104% et 92% par rapport à la monoculture du riz. La dose de 90 kg N/ha a permis d'obtenir le rendement paddy le plus élevé soit une augmentation de 395% par rapport à la dose sans apport d'azote 0 kg N/ha et le poids de 1000 grains le plus élevé. Cependant la dose agronomique la plus efficace quel que soit le précédent cultural est de 60 kg N/ha. Les rotations et les doses d'azote ont un effet sur l'augmentation des rendements du riz paddy en culture pluviale. © 2015 International Formulae Group.

Sci. 9(6): 2847-2858, 2015 2848 Effect of previous crops and different nitrogen levels on the productivity of upland rice on ferruginous tropical soils of the South Sudan region of Burkina Faso ABSTRACTNitrogen is an essential element in the mineral nutrition of rice. In Burkina Faso, more and more, upland rice enters in the crop rotation. However, the yield of upland rice remains under the potential of varieties. To contribute to a better understanding of the mineral nutrition of upland rice, an experimental split plot was tested in Farako-Bâ research station in 2013 and 2014. This was to evaluate the effect of crop rotations and the effect of nitrogen fertilization on yield of upland rice. The results show that the best previous crops of upland rice are legumes, cowpea and peanut. Both previous crops allow a gain of respectively 104% and 92% of yields compared to rice monoculture. The dose of 90 kg N/ha permitted to have highest paddy yield and an increase of 395% compared to the dose without nitrogen 0 kg N/ha and the highest weight of 1000 grains. However, the most effective agronomic dose regardless of the previous crop is obtained with the dose of 60 kg N/ha. Crops rotation and nitrogen level have an effect on upland rice yield.
