“…The crop establishment phase consists of three sub-phases: sowing to germination, germination to emergence, and emergence to initial competition among young seedlings (Aubertot et al, 2020;Lamichhane, 2021a). This study demonstrated that both abiotic and biotic factors affect these sub-phases of sunflower establishment.…”

“…For the damaged seedlings, the type of damage viz., not severe (when the cotyledons were slightly injured without compromising the seedling growth), and severe (when the cotyledons were detached from the stem or the entire seedling was uprooted) was noted . Based on the characteristics of the symptoms, the possible cause of postemergence damage was also noted using a visual diagnostic key (Lamichhane, 2021a). The countings of postemergence damage were performed from the VE to the V4 stages (Schneiter and Miller, 1981).…”

Sowing a second season crop following the harvest of a first crop (hereafter referred to as double cropping) is a practice that allows for temporal diversification of cropping systems to increase the efficiency of land use and yield per unit area while improving the ecosystem services. Sunflower is particularly suitable for double cropping, especially under the current context of Southern Europe. However, planting sunflower in double cropping may result in poor establishment as the crop is very demanding in terms of seedbed preparations. In addition, most sunflower varieties available to date belong to late maturity groups (MGs), which were bred for conventional cropping. Planting these varieties in double cropping may further exacerbate the risk of crop establishment failure. Here, we performed laboratory and growth chamber phenotyping of 11 hybrid oilseed sunflower varieties with contrasting MGs and assessed their field performance for two consecutive years (2020 and 2021). We measured the variables, such as seed germination, seedling emergence dynamics and final rates, and post-emergence damage, as these characteristics are important for a uniform and robust crop establishment. Under laboratory conditions, we found statistically significant effect of varieties on cardinal temperatures and water potential for germination. Under growth chamber conditions, the maximum heterotrophic growth of the hypocotyl was higher (i.e., 85 mm) compared to that of the radicle (i.e., 80 mm). The seedling mortality rates under soil aggregates ranged from 0 to 12%, depending on the size and spatial distribution of soil aggregates in the seedbed. Under field conditions, the final rates of seed germination ranged from 87 to 98% and from 99 to 100%, while those of the seedling emergence ranged from 58 to 87% and from 78 to 94%, in 2020 and 2021, respectively. The average final rates of postemergence damage ranged from 13 to 44% and from 3 to 18% in 2020 and 2021, respectively. Bird damage was the main cause of pre- and postemergence losses. We found that a good sunflower establishment in double cropping is possible in the southwestern conditions of France, provided that there is no water stress in the seedbed. An optimal seedbed moisture ensures a rapid crop emergence and limits pre-and postemergence damage due to birds, by reducing the duration of the crop establishment phase, which is highly vulnerable to bird damage.

“…Agricultural lands are a habitat for several species of birds, especially those that depend on agricultural commodities such as corn for their food source [2] and rice is the living habitat of several species of birds [3] as well as being an important pest in the paddy [4]. Birds pest attack paddy in the vegetative and generative phases [5] and even attack the seeds of paddy in the nursery [6].…”

Birds pest in rice field activities are one of the important pest that attack. It has even caused 161,4 ha of crop loss and 124.05 ha of heavy damage in Riau. This neet to be handled and managed properly. This study was initiated by identifying the types and effects of bird pest attacks on the damage and productionof rice crops in Kuantan Singingi. This study was used a survey method by making plots (10x10 m), bird pests species and populations by using a point transect. Observations were carried out in the morning, afternoon and evening. Bird species identification refers to the MacKinnon Bird Guide in Sumatera, Jawa, and Bali. Diversity of birds pest was calculated by the Shannon-Wienner index, species richness by margaleft index, and species dominance by the Simpson index. This study were observed 1.045 birds attack of paddy field. Koto Kari site was observed 479 individual, 332 individu in Kampung Baru, and 214 in Sangau Lonchura striata was observed as many as 635 individuals. Species diversity index was 0.667, species richness index 0.288, density 0.616 and dominance value 0.527. the highest frequency of bird pest visit was in Koto Kari sithe which was 42 times while based on the species was Lonchura striata71 times with an attack time in the morning of 83 times. The highest damage to panicles by bird pest was caused by Lonchura maja at 46.09% but the highest loss of rice wight was caused by Lonchura striata.

Almost all crops grown around the world can be damaged by rodents, including cereal grains, vegetables, cotton, alfalfa, sugar cane, potatoes, tree fruits, and many others [7].…”

Rodents in Agriculture: A Broad Perspective

There are thousands of rodent species in the world. While they provide a number of ecosystem functions, unfortunately, some species cause significant damage to agriculture. Rodent damage occurs to crops in the field, but also to stored foods, livestock feed, and structures. There are many methods available to reduce rodent populations and/or damage, including both lethal and non-lethal methods. There are advantages and disadvantages to most methods, and many are regulated by federal, state, and local ordinances. Public acceptance of the various methods also varies greatly. Examples and details of these topics are presented in this review.
