“…While global consumption of Brassica crops is expected to increase, substantial yield losses are predicted due to climate change, pests, and diseases ( Rodriguez et al . 2015 ; Phophi and Mafongoya 2017 ). Brassica wild relatives can provide adaptive genetic variation relevant to Brassica crop breeding ( Branca and Cartea 2011 ), but some are endangered and poorly represented in seed banks ( Branca and Tribulato 2011 ; Castañeda-Álvarez et al .…”

Adaptive genetic diversity in crop wild relatives (CWRs) can be exploited to develop improved crops with higher yield and resilience if phylogenetic relationships between crops and their CWRs are resolved. This further allows accurate quantification of genome-wide introgression and determination of regions of the genome under selection. Using broad sampling of CWRs and whole genome sequencing we further demonstrate the relationships among two economically valuable and morphologically diverse Brassica crop species, their CWRs and their putative wild progenitors. Complex genetic relationships and extensive genomic introgression between CWRs and Brassica crops were revealed. Some wild B. oleracea populations have admixed feral origins, some domesticated taxa in both crop species are of hybrid origin, while wild B. rapa is genetically indistinct from turnips. The extensive genomic introgression we reveal could result in false identification of selection signatures during domestication using traditional comparative approaches used previously, therefore we adopted a single population approach to study selection during domestication. We used this to explore examples of parallel phenotypic selection in the two crop groups and highlight promising candidate genes for future investigation. Our analysis defines the complex genetic relationships between Brassica crops and their diverse CWRs, revealing extensive cross-species gene flow with implications for both crop domestication and evolutionary diversification more generally.

“…Fruits are typically more vulnerable to weather extremes, such as high temperatures and soil moisture stress, which cause the crops to shrivel and their leaves to turn yellow [31,32]. A significant greenhouse gas, CO 2 , also has an impact on the development and growth of crops, as well as on the prevalence of insect pests and diseases [33].…”

This study examined the impacts of climate change on okra and tomato yields. Fertilizer consumption and credit to the crop sector were considered as covariates in the analysis. Time-series data, spanning a period of 40 years, were obtained from various sources. An autoregressive distributed lag model was applied to analyze short- and long-term impacts of climate change and agricultural inputs on okra and tomato yields. Not all variables were stationary at levels (order zero), but they were all significant at first difference, indicating the presence of cointegration. The Bound’s test F-ratio was statistically significant and implied the presence of long- and short-term relationships among the variables studied. The mean temperatures had negative impacts on okra and tomato yields in both the short and long terms. Credit guaranteed to the crop sector had positive short- and long-term impacts on tomato yield; fertilizer consumption had a negative long-term impact on okra yield. Our study concludes that climate change, particularly rising temperature, impacts herbaceous fruit crop production in Nigeria. Therefore, we recommend that breeding and disseminating climate-smart tomato and okra varieties will help fruit crop farmers respond to rising temperatures.

“…The constraints in cultivation are the presence of the distraction of pests and diseases that can reduce crop production and quality [5]. Citrus pests and diseases need attention because they can affect productivity and even crop failure, if not managed properly.…”

As a citrus pest, Toxoptera sp. is classified as the main pest because the impact of the attack causes losses to the quantity and quality of the yield. Alternative pest control within insecticides in addition to using a knapsack sprayer or power sprayer is using Bark Pesticide Applicator (BPA), which is a tool to apply systemic pesticides through citrus stems optimally and serves to improve the efficiency of controlling main pests, safe for natural enemies, and environmentally friendly. The study was conducted at the Experimental Farm of the Indonesian Citrus and Subtropical Fruits Research Institute, Batu City, East Java, Indonesia from January to May 2018. This study compared the effectiveness of pesticide application devices using BPA and Power Sprayer (PS). The treatment was arranged using a randomized block design and repeated ten times. The test results showed that the application of pesticides with BPA was able to control aphids up to 93.84 % while PS was only able to suppress 29.48 %. Whiles the existence of natural enemies can be saved if the application of pesticides is carried out using BPA
