Cassava production in Indonesia is relatively high. Ofcourse, it will produce much waste, such as Cassava Peel (CP) and Cassava Leaf (CL). Casava peel and casava leave has the potential to be used as feed ingredients but is constrained by low quality, and they can only be used 10% in poultry rations. For that, it is necessary to research to improve the quality of Cassava Peel-Leaf Mixture (CPLM) through fermentation with R.oligosphorus as a poultry ration. This experimental study uses a completely randomized design (CRD) with four treatments and five replications. The treatments were cassava peel-leaf mixture (CPLM) fermented with R. oligosphorus. The Treatments were A (9:1), B (8:2), C (7:3), and D (6:4). The variables observed were the digestibility of crude fiber (DCF), the activity of protease enzymes, crude protein (CP) nitrogen retention (RN), metabolic energy (ME), and crude fiber (CF). The diversity analysis showed a very significant effect (P<0.01) on (DCF), crude protein (CP), protease activity, crude fiber (CF), nitrogen retention (RN), and energy metabolism (ME) of CPLM fermentation. Based on the study’s results, it can be concluded that CPLM (6:4) fermented with R.oligosphorus gave the best results.

This study reviews ten years of data on the production of broiler chicken and per capita consumption patterns from 2011 to 2020, in the Sulaymaniyah governorate in KRI. The data from this study explain that more than half of the broiler chicken production projects are located in the Sulaymaniyah governorate. Thus, the growing number of poultry projects has significantly contributed to increasing local broiler chicken meat production by 6 folds and achieving 85.44% of self-sufficiency in broiler chicken meat production, even though their productivity is lower than their production capacity due to the high rate of broiler chicken mortality and uncertain supply chain management. Furthermore, frequent fluctuations and instability in the production rates are observed during the last decade, as broiler chicken meat production increased from 1,669.77 tonnes in 2011 to 20,034.06 tonne in 2015, then dropped to 11,802.36 tonnes in 2016 then rose again to 23,816.13 tonnes in 2019 and then declined again to 11,352.23 tonnes in 2020. These fluctuations and instabilities in local production may harm agri-food production sustainability and food security in the KRI in general, and, the Sulaymaniyah governorate in particular.

Geographical factors (i.e., geology, slope, elevation and temperature) and genetic variability in different olive cultivars influence plant growth, yield, oil and profiling of fatty acids. The prime objective of this investigation was to demonstrate the prodigious consequences of high temperature on the growth, production, and fatty acid composition of four olive cultivars (Coratina, Frantoio, Ottobratica and Leccino) at three different geographical locations (BARI, IOF, HRS) with the range of 460-751 m altitude during the year 2017 and 2018. The study has been carried out to investigate different parameters such as climatic conditions (rainfall and temperature), phenological attribute and yield traits (fruit set, fruit weight, yield, and oil content), and oil quality and profiling of fatty acids (free fatty acid contents, peroxide, palmitic acid, palmitoleic acid, oleic acid, linoleic acid, and linolenic acid). The results indicated a positive correlation of yield with rainfall and negative with the temperature was observed among olive cultivars. The results showed higher rainfall (1189 mm) and temperature (37.51 °C) at location-1 and lower rainfall (525 mm) and temperature (36.05 °C) at location-3. Coratina and Frantoio depicted significantly higher fruit set and yield in warmer climatic regions (Location-1 and Location-2) while Leccino and Ottobratica showed better results in the cooler region. Higher oil content was found in Frantoio and Coratina at location-3 among other locations and other cultivars. Overall, the lowest free fatty acid value was exhibited in Coratina and the highest in Ottobratica at all locations in both seasons. The contents of peroxide were observed higher in Leccino and lower in Coratina at all locations. The results revealed less variation among fatty acid composition in cultivars and seasons, however, palmitic acid, palmitoleic acid and oleic acid contents were found higher at location-2, linoleic acid at location-3, and linolenic acid at location-2 in all four olive cultivars. Custer analysis revealed two main groups and group-I contained two subgroups (A and B) while group-II contained three subgroups (C, D and E). In principal component analysis (PCA), PC1 axis had Leccino-L3, Leccino-L1, Frantoio-L1, Ottobratica-L1, Coratina-L1, and Leccino-L3 and explained 91.99% of the total variation.

Allium crops are highly vulnerable to many notorious RNA viruses fit in different genera viz., Allexivirus, Potyvirus, Tospovirus and Carlavirus. These viruses are known to inflict colossal and havoc yield losses up to 50% in allium crops wherever they grown. The occurrence of allium viruses in Pakistan has already been reported, but in single crop and only a few studies describe their incidence and distribution. The study examined the current scenario and distribution of major RNA viruses infecting Allium crops in Punjab, Pakistan. Field surveys were carried out in 14 districts of Punjab province as well as capital territory Islamabad of Pakistan, for two consecutive growing seasons (2019 and 2020). The 3000 leaf samples collected, 1675 samples (Onion 791, Garlic 884) were found positive for RNA viruses by using specie specific DAS-ELISA and further confirmed through reverse transcriptase polymerase chain reaction (RT-PCR). The results revealed the presence of RNA viruses with overall disease incidence of 52.7% and the highest disease incidence was observed as Onion yellow dwarf virus (OYDV) 58% following Irish yellow spot virus (IYSV) 41.8% respectively in onion crop during 2019-2020. Similarly, in garlic crop overall disease incidence of RNA viruses was noticed as 58.9% and the highest disease incidence of OYDV was observed as 45%, following IYSV 32.4% and GarV-C 22.5% respectively during 2019-2020. Comparatively, disease incidence and geographical distribution of viruses was variable in surveyed regions of both crops during surveyed period, whereas OYDV and IYSV were most prevalent viruses infecting onion and garlic crops and GarV-C found only in garlic. The current study also concluded the importance to disseminate the information/awareness among the farmers regarding viral diseases and their management by using different strategies including use of resistant genotypes.

A total of 441 specimens were collected regardless of showing symptoms and assayed for Barley/Cereal Yellow Dwarf Viruses [B/CYDV] association by PCR tests using virus coat protein gene (CPG)-specific primer pairs. These assays demonstrated that 13.38% (55 samples) were positive to the occurrence of BYDV-PAV (9.73%) and CYDV-RPV (0.73%) for wheat viruses, but no BYDV-MAV, -SGV, and -RMV infections of BYDVs were found in PCR assays of collected samples. In addition, double infection of BYDV-PAV and CYDV-RPV was detected in 12 samples with a 2.91% infection rate. The CPG sequences of randomly selected two isolates were revealed using bacterial cloning and sequencing.
