Anbarashan M, Padmavathy A, Alexandar R. 2017. Short Communication: Survival and growth of mono and mixed species plantations on the Coromandel coast of India. Asian J For 1: 70-76. There exists very little information on the growth of autochthonous tree species autochthonousin the tropics and on the experiences in conducting mono and mixed species plantations. The aim of this study was to compare the variation in growth parameter between the mixed species plantation and mono species plantation. The growth, survival, and height of 82 autochthonous mixed species plantations were compared with Casuarina equisetifolia, an exotic species broadly planted in this region after over a decade (2006 to 2016). In the mixed species plantation, seven species showed 100 % survival rate and 19 species were not survived after 10-year intervals. In the mono species plantation, Casuarina equisetifolia had 92 % of the survival rate. When it is compared to the mono plantation, the growth rate of mixed species plantation showed highly significant differences (P < 0: 05) values. Simple linear regression between annual girth increment and height produced very strong positive relations (R2 0.759). Plantations of Casuarina equisetifolia seem to be well adapted to the coastal region. On the other hand, mixed plantation with autochthonous species would contribute more to sustainable management because they provide a greater range of ecological goods and ecosystem services than the single species plantations.

Abstract Various soil types (loamy and sandy soils) were seeded with Kentucky coffeetree, treated with preemergent herbicides and grown in the greenhouse to determine their effect on seedling survival and growth. Tested were Lasso (alachlor) at 2.2 (2.0), Tenoran 50W (chloroxuron) at 2.2 (2.0), Dacthal (DCPA) at 11.2 (10.0), Eptam (EPTC) at 4.5 (4.0), Devrinol (napropamide) at 1.1 (1.0), Ronstar (oxadiazon) at 4.5 (4.0) and Tolban 4E (profluralin) at 0.6 (0.5) kg ai/ha (lb ai/a). All treatments tested allowed acceptable survival (82%) and height or dry weight growth.

Mixed-species forest plantation is a sound option to facilitate ecological restoration, plant diversity and ecosystem functions. Compatible species combinations are conducive to reconstruct plant communities that can persist at a low cost without further management and even develop into natural forest communities. However, our understanding of how the compatibility of mycorrhizal types mediates species coexistence is still limited, especially in a novel agroforestry system. Here, we assessed the effects of mycorrhizal association type on the survival and growth of native woody species in mixed-species Eucalyptus plantations. To uncover how mycorrhizal type regulates plant-soil feedbacks, we first conducted a pot experiments by treating distinct mycorrhizal plants with soil microbes from their own or other mycorrhizal types. We then compared the growth response of arbuscular mycorrhizal plants and ectomycorrhizal plants to different soil microbial compositions associated with Eucalyptus plants. We found that the type of mycorrhizal association had a significant impact on the survival and growth of native tree species in the Eucalyptus plantations. The strength and direction of the plant-soil feedbacks of focal tree species depended on mycorrhizal type. Non-mycorrhizal plants had consistent negative feedbacks with the highest survival in the Eucalyptus plantations, whereas nitrogen-fixing plants had consistent positive feedbacks and the lowest survival. Arbuscular mycorrhizal and ectomycorrhizal plants performed varied feedback responses to soil microbes from distinct mycorrhizal plant species. Non-mycorrhizal plants grew better with Eucalyptus soil microbes while nitrogen-fixing plants grew worse with their own conspecific soil microbes. Different soil microbial compositions of Eucalyptus consistently increased the aboveground growth of arbuscular mycorrhizal plants, but the non-mycorrhizal microbial composition of the Eucalyptus soil resulted in greater belowground growth of ectomycorrhizal plants. Overall, Eucalyptus plants induced an unfavorable soil community, impeding coexistence with other mycorrhizal plants. Our study provides consistent observational and experimental evidence that mycorrhizal-mediated plant-microbial feedback on species coexistence among woody species. These findings are with important implications to optimize the species combinations for better design of mixed forest plantations.

Abstract Sixteen hardwood species were planted in different arrangements in two experiments in a former field with an imperfectly drained silt loam soil in Middlesex County, Ontario. With few exceptions planting arrangement had little effect on 10-year survival and on height and diameter increment. However, overall survival and growth were slightly better in the row planting than in the completely random mixture. Applications of 3.3 kg/ha of active simazine in each of the first 3 years after planting provided adequate weed control. One additional application of 2 kg/ha of active glyphosate in June of the sixth growing season eliminated 80% of the competition, renewed tree vigor, and enabled the trees to close the canopy and thereby provide their own weed control through shading. Recommendations are made for the establishment of mixed hardwood plantations in southern Ontario. North. J. Appl. For. 5:203-207, Sept. 1988.

Various soil types were seeded with honey locust (Gleditsia triacanthos L.) and treated with preemergent herbicides to determine their effect on germination, seedling survival, and growth. Tested were alachlor at 2.2 (2.0), chloroxuron at 2.2 (2.0), DCPA at 11.2 (10.0), EPTC at 4.5 (4.0), napropamide at 1.1 (1.0), oxadiazon at 4.5 (4.0) and profluralin at 0.6 (0.5) kg ai/ha (lb ai/A). Acceptable survival and growth was found for all but oxadiazon which significantly reduced survival in the sandy loam soils.
