Opis:
The obligate oomycete Sclerospora graminicola (Sacc.) Schroet, is the incitant of downy mildew disease, which is the main constraint in pearl millet production worldwide. Different elicitors from Trichoderma hamatum UOM 13, e.g. mycelial extract and cell wall glucans, were assessed for their resistance elicitation efficiency and the possible underlying mechanisms. Both mycelial extract and cell wall glucans of T. hamatum UOM 13 positively influenced seed quality parameters of pearl millet, significantly enhanced seed germination and seedling vigor in comparison to the untreated control. Seed priming with cell wall glucan elicitors of T. hamatum UOM 13 suppressed downy mildew on susceptible pearl millet seedlings under greenhouse conditions by induction of systemic host resistance. Of the different elicitor delivery methods tested, transplant root dip was more effective than seed treatment and foliar spray. A combination of transplant root dip + seed treatment + foliar spray was significantly more effective than the single delivery methods. The induced resistance corresponded to up regulation of genes of important defense proteins upon pathogen inoculation. Transcripts of genes of defense enzymes glucanase, phenylalanine ammonia lyase, peroxidase and polyphenoloxidase were significantly increased due to the T. hamatum UOM elicitor effect. Expression of hydroxyproline-rich glycoprotein genes, known to play an important role in cell wall cross-linking, were also up regulated in response to T. hamatum UOM cell wall glucan treatment. This study emphasizes the role of T. hamatum UOM as a potential elicitor of downy mildew resistance in pearl millet and presents novel insights into the involvement of important defense proteins mediating such as resistance trigger.

Opis:
Field experiments were separately conducted from June to November, in year 2012 at the Research Farm, University of Agriculture, Makurdi, Nigeria and at a Farm in Ibi, Nigeria, to evaluate the effects of intra-row spacing of pearl millet and cropping systems on growth and yields of soybean-pearl millet intercrop, as well as assessing the yield advantages of the intercropping system. The experiment was a 2 x 4 factorial combination of treatments, fitted in a randomized complete block design (RCBD), with four replications. The cropping systems constitute the soles and the intercrop, while the intra-row spacing of pearl millet into soybean were at 15 cm, 20 cm, 25 cm and 30 cm. Results of study showed that sowing pearl millet into soybean at the intra-row spacing of 30 cm produced the highest pearl millet yields of 4.7 t ha-1 and 4.9 t ha-1 respectively, at Makurdi and Ibi locations, as well as producing the highest soybean yields at both locations. In Makurdi, intercropping pearl millet with soybean significantly (P ≤ 0.05) decreased yield of pearl millet by 32.4 % and that of soybean by 29.4 % compared to sole cropping of the component crops, while at Ibi, intercrop yields of pearl millet and soybean were respectively reduced by 35.9 % and 30.0 % compared to their sole yields. Sowing pearl millet into soybean at the intra-row spacing of 30 cm also gave the highest total intercrop yields, highest land equivalent coefficient (LEC) values, highest land equivalent ratio (LER) values of 2.97 and 2.71 and highest percentage (%) land saved (66.3 % and 63.1 % respectively, recorded at Makurdi and Ibi locations). The implication of study showed that it is most advantageous having both crops in intercrop when pearl millet was sown into soybean at the intra-row spacing of 30 cm. This should therefore, be recommended for the southern guinea savanna, Nigeria.

Opis:
A field experiment was conducted from June to November, during the 2013 and 2014 cropping seasons at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the effects of intra-row spacing of pearl millet and cropping systems on the productivity of soybean-pearl millet intercrop and to assess the yield advantages of the intercropping system. The experiment was a 3x4 factorial arrangement of treatments, fitted in a randomized complete block design (RCBD), replicated four times. The cropping systems (sole soybean, sole pearl millet and soybean-pearl millet intercrop) constituted the main plots, while the intra-row spacing of pearl millet (15 cm, 20 cm, 25 cm and 30 cm) into soybean were allocated to the subplots. Results of study showed that to maximize intercrop yields of soybean and pearl millet in a soybean-pearl millet intercrop, the optimal intra-row spacing for pearl millet is 30 cm. Intercropping soybean and pearl millet significantly (P ≤ 0.05) reduced yields of soybean (25.0 % and 22.2 % respectively, in years 2013 and 2014) and that of pearl millet (34.4 % and 33.3 % respectively, in years 2013 and 2014). Though, the highest land equivalent ratio (LER) values, highest land equivalent coefficient (LEC) values and lowest competitive ratio (CR) values were recorded for pearl millet sown into soybean at the intra-row spacing of 15 cm, however, highest aggressivity was obtained sowing pearl millet into soybean at the intra-row spacing of 25 cm, the level at which both crops dominated each other.
