Pre-extension demonstration of field pea varieties in selected districts of Bale highlands, Oromiya national regional state, Ethiopia

Pre extension demonstration of improved field pea varieties was conducted in Goba, Sinana and Agarfa districts of Bale zone. The main objective of the study was to demonstrate and evaluate recently released (Weyib) variety along with standard check. The demonstration was under taken on single plot of 10mx10m area for each variety with the spacing of 30cm between rows and recommended seed rate of 75kg/ha and fertilizer rate of 100kg/ha NPS. Mini-field day involving different stakeholders was organized at each respective site. Yield data per plot was recorded and analysed using descriptive statistics, while farmers’ preference to the demonstrated varieties was identified using focused group discussion and summarized using pair wise ranking methods. The demonstration result revealed that Weyib variety performed better than the standard check (Tulu shanan variety) with an average yield of 34.47qt/ha, while that of the standard check was27.26qt/ha. Weyib variety had 17.27% yield advantage over the standard check. Thus, Weyib variety was recommended for further scaling up. Res. Agric., Livest. Fish.8(3): 267-271, December 2021

​Impact of Cluster Front Line Demonstrations on Productivity and Economics of Lentil (Lens culinaris L.), Chickpea (Cicer aeritinum L.) and Field Pea (Pisum sativum L.) in Old Alluvial Zone of Malda, West Bengal, India

Background: There are significant gaps in yields of pulses among potential, demonstration and farmers’ plots in West Bengal. This is mostly due to adoption of traditional local varieties and poor cultivation practices. Methods: The yield, technology and extension gaps were studied on improved varieties of lentil, chickpea and field pea during rabi seasons of 2017/18-2020/21 in 80 hectare area of Malda, West Bengal with 205 farmers. Result: The highest and lowest magnitude of technology index (TI) was observed in field pea var. IPFD-10-12 (44.5%) during 2018/19 and in lentil var. KL-320 (30.1%) during 2020/21. Among lentil varieties, the highest benefit cost ratio was obtained from KL-320 (2.87) whereas in case of chickpea, it was obtained from NBEG-49 (2.90). For field pea var. IPFD-10-12 the benefit cost ratio was 2.70. Maximum and minimum extension yield gaps were observed in field pea var. IPFD-10-12 (451 kg ha-1) during 2018/19 and in lentil var. IPL-406 (145 kg ha-1) during 2018/19. Overall assessment reflects lentil var. KL-320, chickpea variety NBEG-49 and field pea variety IPFD-10-12 have good potentiality and most suitable for this region. So, it is hypothesized that improved farm technology has enormous potential to scale up pulse productivity through cluster front line demonstration (CFLD).

Glyphosate- and acetolactate synthase inhibitor-resistant kochia (Bassia scoparia) control in field pea

Kochia [Bassia scoparia (L.) A.J. Scott] is an invasive C4 tumbleweed in the Great Plains of North America, where it impedes crop harvest and causes significant crop yield losses. Rapid evolution and spread of glyphosate- and acetolactate synthase (ALS) inhibitor-resistant kochia in western Canada limit the herbicide options available for control of these biotypes in field pea (Pisum sativum L.); one of the predominant pulse crops grown in this region. Field experiments were conducted near Lethbridge, Alberta in 2013-2015 and Coalhurst, Alberta in 2013-2014 to determine which herbicide options effectively control glyphosate- and ALS inhibitor-resistant kochia in field pea. Visible injury of field pea was minor (0-4%) in all environments except for Lethbridge 2013, where pre-plant (PP) flumioxazin and all treatments containing post-emergence (POST) imazamox/bentazon resulted in unacceptable (14-23%) pea visible injury. Herbicide impacts on pea yield were minor overall. Carfentrazone + sulfentrazone PP and saflufenacil PP followed by imazamox/bentazon POST resulted in ≥80% visible control of kochia in all environments, while POST imazamox/bentazon alone resulted in ≥80% reduction in kochia biomass in all environments compared with the untreated control (albeit absent of statistical difference in Coalhurst 2014). These results suggest that layering the protoporhyrinogen oxidase-inhibiting herbicides saflufenacil or carfentrazone + sulfentrazone PP with the ALS- and photosystem II-inhibiting herbicide combination imazamox/bentazon POST can effectively control glyphosate- and ALS inhibitor-resistant kochia in field pea while also mitigating further selection for herbicide resistance through the use of multiple effective herbicide modes-of-action.
