Effect of Pruning and Micronutrient Sprays on Physico-chemical Properties of Ber

An investigation was undertaken to study the effect of pruning height and micronutrients on the physicochemical properties of ber. The experiment was conducted in the farmer’s field at Manikpur area of Bongaigaon district, Assam (26026¢51² North latitude and 90046¢47² East longitude) for two consecutive years. Two types of Thailand ber were exposed to two different pruning heights and eight different micronutrient spray combinations. Results depicted that Roundish ovate reddish type variety performed better. The highest total sugar content (14.91%), TSS/acid ratio (44.07) and ash content (2.66%) were observed at a pruning height of 75 cm. Among micronutrients, borax at 0.5% and zinc sulphate (ZnSO4) at 0.5% in combination proved to be better in terms of total sugar (14.83%) and ash content (2.64%). So, the experiment proved that a pruning height of 75 cm from the ground level and spraying of borax 0.5% and zinc sulphate 0.5% in combination, were better compared to the other treatments.

Evaluation of Visual and Functional Quality of Grass and Trees at RSJMM Heritage Golf Field in Bogor City

Abstract RSJMM Heritage Golf Club is the oldest golf course in Bogor City. The quality of a golf course depends on the quality of the grass, both visually and functionally. It is also influenced by the tree that performs as a natural challenge for the game. The objectives of this study are: (1) to evaluate the visual quality of grass and trees, (2) to evaluate the functional quality of grass, and (3) to propose maintenance plan recommendations. The methods used in this research were observation, interview, and literature review. Furthermore, the data obtained were analyzed using Pearson correlation, Binomial test, and Kruskal-Wallis test. The result shows that the average visual quality of the tree is categorized as very good. Meanwhile, the visual quality of the grass shows that grass density is classified as moderate for the green area and high for the tee box and fairway areas. The color, color uniformity, the presence of particles, and the texture of 3 areas met the standard. The functional quality of the grass indicated that pruning height in 3 areas, shoot dry weight, root dry weight, and root length other than 1 area met the standard. The elasticity of the grass is included in the category of fast and medium fast for regular play. The result of this study provides recommendations for a maintenance plan to develop the quality of RSJMM Heritage Golf Club.

Effect of pruning height and organic fertilization on the morphological and productive characteristics of Moringa oleifera Lam. in the Peruvian dry tropics

Abstract The objective of the study was to evaluate the effect of pruning height (PH) and organic fertilization dose (FD) on the morphology and productive characteristics of Moringa oleifera Lam. We germinated seeds collected from 10-year-old shrubs, and 2-month-old seedlings were transplanted in the final field. We used a two-factor design of PH (PH1:0.4, PH2:0.8, and PH3:1.2 m from the ground) and FD (FD0:0, FD1:500, FD2:750, and FD3:1,000 g of decomposing goat manure). We carried out an initial pruning 4 months after transplanting and the harvests every 45 days. After three consecutive harvests, PH3 improved N° branches (12.53 ± 3.09) and dry matter (21.98 ± 1.30%), but PH1 showed greater stem lengths (1.65 ± 0.24 m) (p < 0.01). There was no difference in the stems and leaf weights between PH2 and PH3, and no trait varied according to FD (p > 0.05). The PH × FD interaction can improve the plant diameter (p < 0.01) and dry matter (p < 0.05) with PH2 (56.79 ± 3.71 mm) and PH3 (23.20 ± 1.04%) from FD1. We found an increasing trend in N° branches, plant diameter (p < 0.01), and the leaf–stem ratio. However, in the third harvest, the biomass production trend was downward for a short period for an adequate replacement of nutrients from the incorporated organic fertilizer. It is recommended to prune M. oleifera at 1.2 m from the ground to stimulate greater biomass and maintain the leaf–stem ratio throughout the evaluated harvests and apply more than 500 g of goat manure after each harvest to restore the nutrients extracted from the soil.

Effect of Pruning Treatment on Growth Characteristics and Metabolites in Eucommia ulmoides Oliver (E. ulmoides)

The effect of pruning treatments on growth, photosynthesis characteristics, and metabolites were was studied in Eucommia ulmoides Oliver (E. ulmoides). The experiment was carried out from March–August 2019. Three treatments were used: non-pruned trees (CK), a height of 20 cm above the top edge of the flowerpot (T1), and a height of 10 cm above the top edge of the flowerpot (T2). The results showed that the branches branch number, leaves leaf number, and stem diameter increased significantly (p < 0.05) in pruning treatments compared with CK. Similarly, the net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), maximum photosynthetic efficiency (Fv/Fm), and non-photochemical quenching coefficient (NPQ) increased significantly in pruning treatments (p < 0.05). Interestingly, the contents of Chl a, Chl b, Chl, Car, and the rate between the Chl a content and the Chl b content increased significantly (p < 0.05) in T2, respectively. These verified that it was a better way to enhance the plants growth of E. ulmoides for pruning treatments. The GC-MS analysis showed that 36 different primary metabolites were identified, including 11 sugars, 13 acids, 5 alcohols, and 7 other compounds, the relative content of their metabolites were was higher in the T2 treatment than that in the T1 treatment, which was mainly concentrated in four main enrichment pathways (Galactose metabolism; Citrate cycle; Glyoxylate and dicarboxylate metabolism; and starch and sucrose metabolism) via KEGG analysis. Meanwhile, correlation analysis showed there were was a positive correlation between the accumulation of D-Galactose, D-Mannose, Succinic acid, and photosynthetic pigment content, and the rate of photosynthesis in T2 treatment (p < 0.05). The pruning height above the top edge of the flowerpot changed the accumulation of primary metabolites and promoted plant regeneration ability in E. ulmoides. Finally, the yield of main secondary metabolites from leaves (Genipin, Geniposide, Geniposidic acid, and Pinoresinol diglucoside) were was increased in pruning treatments by UPLC analysis. It provided a reference for the directional ecological cultivation of E. ulmoides.

Vegetative Recovery of Yerba-Mate (Ilex paraguariensis St. Hil) Crop by Coppicing

Background: Yerba-mate (Ilex paraguariensis) is a perennial native tree from South America. Improper management of yerba-mate crops results in low yield. This work evaluated the recovery and the vegetative capacity of the crop after coppicing. Methods: A 2-year field observation approach was used and the study area was monitored from 2019 to 2021 in a 20-year-old yerba-mate crop with low yield. Drastic coppicing was used as a strategy, aiming to study the effect of the month and the height of pruning. Four groups were defined combining the trunk heights of 10 and 40 cm and the months of pruning June and August. Results: Yerba-mate plants showed a low mortality rate of 2%. In the first year after the intervention, the height of the cutting was the most important factor that influenced the amount of primary and secondary branches, validating response surfaces with r2 values of 0.9942 and 0.9084, respectively. In the second year of the experiment, full recovery in productivity was reached, with a mean rise of 109.7% in the plants of the group coppiced in June 40 cm above the soil. Conclusion: The techniques used in this study are appropriate for vigor recovery in yerba-mate plants inadequately managed and allow a new architecture on plants, enabling mechanical harvesting.

Response of Shoot Pruning on Growth, Flowering and Fruiting Characteristics of Guava under Sub-Himalayan Terai Region of West Bengal

Guava is one of the important fruit crops grown worldwide. Shoot pruning improves the emergence of new flush and its role on flowering and fruiting characteristics was evaluated on this experiment. The effect on shoot pruning height and removal of top leaf bud by pinching was assessed on growth, flowering and fruiting characteristics of guava cv. L-49. The experiment was conducted at Uttar Banga Krishi Viswavidyalaya There were two factors heading back and pinching. Heading back at the level of, Pundibari, Cooch Behar, West Bengal. 90, 120 and 150cm was done in January and pinching of one leaf pair was performed during the last week of June, 2018.The heading back at the level of 120 cm and no pinching were most effective for number of flowering bud (179.33), number of flowers (139.83), number of fruit set (95.33), total number of fruits (64.66), ascorbic acid (190.35 mg/100g), titratable acidity (0.28%) and heading back at the level of 120 cm and one pinching were effective in increasing number of primary shoots (39.50), flowering percentage (80.18%), fruit weight (172.00g).

Farmers’ Compliance with Standard Silvicultural Practices and its Impact on the Performance of Pinus Spp. Woodlots in Rubanda District, South-Western Uganda

This study investigated farmers’ compliance to standard silvicultural practices and its impacts on the performance of Pinus spp in plantations in Rubanda District, South-western Uganda. A total of 122 pine plantations were randomly selected for intensive assessment. The findings revealed an average spacing of 2.90m, which significantly differs from the standard spacing of 3.0m for pine. Generally, stem density of pine plantations at various age categories such as 8 and 10 years was significantly higher than the recommended. The overall average pruning height of 3.26m as practiced by the farmers was significantly lower than 6.81m, the standard requirement of 50% average tree height (p≤ 0.05). In comparison, there were significant differences in average dbh in the three stem density categories. The increase in stem density caused a corresponding decline in dbh of trees in the pine plantations. Farmers with a pine crop of seven years and above with tree stock above the recommended stem density had incurred an average loss of 70.5m3 per hectare leading to an equivalent financial loss of UGX 3,525,000/= (USD 952.7) per hectare. Therefore, to avoid competition and unnecessary financial loss, adjustment of stem density by thinning as the pine plantation grows is strongly recommended.

Effect of Plant Growth Regulator on Growth, Yield and Catechin Content of Tea (Camellia sinensis (L.) O.Kuntze)

Catechins are one of the secondary metabolites contained in tea leaves. Cultivation practices such as pruning affect the shoot production and quality of tea yield. The use of plant growth regulators is a new breakthrough in tea plant engineering. This research aims to determine the interaction effect of type, height of pruning, and concentration of Benzil Amino Purine (BAP) and Gibberellin (GA) concentrations on tea plants' growth and catechin content after pruning. The experiment was conducted at Tea and Cinchona Research Centre Gambung in June 2018 until October 2018, with a split-plot design consisted of three factors as followed: main factor (a) type of pruning (clean and lung pruning); subfactor (b) pruning height (40 cm, 50 cm, and 60 cm); sub-sub factor (h) plant growth regulator (0 ppm, 60 ppm BAP, 50 ppm GA, 60 ppm BAP + 50 ppm GA). The result showed that 60 cm pruning and 60 ppm BAP in the third month after pruning significantly affected the chlorophyll content index (91,58I cci). There was an interaction between the pruning height of 60 cm and 50 ppm GA on fresh shoots weight per bush on the fourth plucking. Based on the response curve, at clean pruning, the optimum value at pruning height of 51.5 cm and 66,63 ppm BAP contributes to the catechin content of 1.88% while at lung pruning, the minimum value pruning height of 50.73 cm and 7.238 ppm with catechin content of 0.776%.

Higher Renovation Pruning Height Improves Early Yields of ‘Woodard’ Rabbiteye Blueberry

Rabbiteye blueberry (Vaccinium virgatum) bushes are relatively easy to grow and commonplace across Mississippi; however, if not properly maintained, the bushes will decline over time. Eighteen, aged, low-productivity ‘Woodard’ rabbiteye blueberry bushes were pruned at two different heights (ground level and a 50-cm above ground level) after harvest in July 2017, and phosphorous acid was applied as a drench and foliar spray in the first year, but this was discontinued as the applications had no effect on the bushes. For two seasons, fruit yields were collected and weighed, bushes were measured for growth parameters, and canes were weighed. Bushes pruned at the 50-cm above ground level had much higher yields in both 2019 (3.47 vs. 0.63 kg) and 2020 (3.91 vs. 1.23 kg), thus providing a substantial yield benefit. The 50-cm above ground level pruning treatment bushes produced more canes by the end of the study, therefore accounting for more fruiting area, as seen in the harvest index. In short, pruning old, nonproductive bushes at a 50-cm above ground level can provide growers with greater potential for early economic returns than pruning at ground level, for ‘Woodard’ rabbiteye blueberry.

Pruning on Moringa trees aims to increase branching that affects the increase in yield of leaf biomass, and is also routinely carried out with the aim of plant performance provides benefits for ease of maintenance and harvesting as well as the sustainability of production. This pruning study aims to determine the effect of high pruning on the yield of Moringa leaf biomass in the third year of the production cycle, has been carried out in rainfed lowland rice fields. Randomly block designed trials with high pruning as a single factor, namely pruning at a height of 25 cm, 50 cm, 75 cm, and 100 cm from the ground, and was made in three replications. The results showed that the height of pruning had no significant effect on the yield of Moringa leaf biomass in the third year of the production cycle.

EFFECT OF PRUNING HEIGHT ON THE PRODUCTION OF ORTOTROPIC BUDS OR BRANCHES IN VIVERO CONDITIONS

Introduction: reforestation constitutes an imperative need for current generations; this guarantees the sustainability of wood for different purposes, while promoting healthy conditions for the environment; The scientific community redouble efforts to investigate techniques that make reforestation increasingly feasible and viable. Objective: To determine the effect of pruning height according to the number of buds in the production of orthotropic shoots or branches under nursery conditions. Methodology: experimental, descriptive and longitudinal study in which young plants of Juglans neotrópica were subjected to clonal forestry techniques by means of training prunings in mother plants Different statistics were used to identify the statistical significance of the changes in the appearance of shoots according to the pruning height and number of buds; These include the use of Pearson's chi-square, the correlation for continuity, the likelihood ratio and the linear association for linear. Results: the plants submitted to the A2S2 combination were the ones that showed the best yield in relation to the appearance of shoots. The plants subjected to the A1S1 and A2S2 combinations were the ones with the greatest delay in the appearance of shoots. Conclusions: there is no significant relationship between the appearance of shoots and the height of pruning according to the number of buds; therefore, it can be determined that the buds will appear interchangeably whether the pruning is performed at three or five buds.

Pengaruh Pemangkasan dan Aplikasi Sitokinin terhadap Pertumbuhan dan Hasil Tanaman Teh (Camellia sinensis)

<em>Pruning on tea plants is an ecophysiological manipulation to initiate the growth of new shoots as the formation of pecco shoots. Cytokinin, one of which is benzyl amino purine (BAP), is a growth regulator that can be applied to stimulate shoot initiation after being pruned. The objective of this study was to determine the effect of pruning and cytokinin application on the growth and yield of tea. The study was conducted at the Experimental Station of the Tea and Quinine Research Center, Gambung at an altitude of 1250 m above sea level (asl), from June to August 2018. Plant material used in this study was a 7-year-old GMB 7 clone. The exerimental design used was a randomized block design (RBD) consisting of eight treatment combinations with four replications and contained 32 experimental units. The treatments used were clean and jambul/ajir pruning, 40 cm and 60 cm pruning height and BAP concentration. The variable observed were number of pecco shoots, number of banji shoots, fresh weight and dry weight of shoots. The results showed that the combination of type and height of pruning with the BAP application affected the number of pecco and banji shoots on the third picking, but did not affect the fresh and dry weight of shoots. The treatment of clean and jambul/ajir pruning at 60 cm height and added with BAP application at 60 ppm exhibited the best treatment in producing the number of shoots and reduce the number of banji shoots.</em>

Auswirkungen der Wertastung auf das Douglasien-Wachstum: Ergebnisse aus Nordwestdeutschland

Effects of pruning on the growth of Douglas-fir: findings from northwestern Germany Owing to Douglas-firs' insufficient self-pruning ability, for the production of high-grade wood, manual pruning is mandatory. Pruning of live branches increases the branch-free tree volume considerably. Branchiness is important for grading wood quality, but with pruning this detrimental characteristic loses its significance for the value of the Douglas-fir asset. In 1980, trials were conducted in the forest district of Ahlhorn (Lower Saxony, Germany) with three-year-old Douglas- firs to test the effects of live pruning on tree growth. The sample material consists of 93 trees which were periodically pruned beginning from a height of 6 to 8 m up to 20, 40 and 60% of tree height, as well as of 9 Douglas-firs of the unpruned control group. However, only specimens with a pruning height of 60% had live branches removed at each pruning. By means of a multivariate linear regression model the effects of pruning on the dependent variates diameter at breast height (dbh), tree height, stem taper of the butt log and maximum branch diameter approximately at a whorl's height of 5 m were studied up to the age of 39 years. Pruning of live branches had a significant effect on periodic radial growth as well as on bottom log allocation, though not on tree height or branch diameter. Live prune led to moderate reduction of radial increment and had a positive effect on stem taper. The results of the study largely agree with earlier studies on the effects of pruning on Douglas-fir growth.

Standardization of pruning height, pruning interval and foliar nutrients on growth and yield of curry leaf (Murraya koenigii Spreng.)

A field experiment on effect of pruning height and pruning interval on growth, yield and quality of curry leaf (Murraya koenigii Spreng.) was conducted at the Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam during 2015. The experiment was laid out in split-split design consisting of three factors, viz., factor – I pruning level (L1 – 15 cm and L2 – 30 cm), factor – II pruning interval (P1 – 2 months interval of harvest and P2 – 3 months interval of harvest) and factor – III foliar applications of biostimulants (N1 – 0.25% ZnSO4, N2 – 0.25% FeSO4, N3 – 2% seaweed extract and N4 – 0.3% humic acid) constituting 17 treatment combinations. Biometrical observations were made from randomly selected five plants and subjected to statistical analysis. The result reveled that, among the two levels of pruning, two intervals of pruning and foliar nutrients registered the highest growth character viz., plant height (139.30 cm), number of secondary branches (9.40 plant-1), stem girth (21.34 cm), leaflet length (7.30 cm), leaflet width (4.3 cm) and leaf area (11.98 cm2). It was also observed that the yield characters viz., leaf yield (0.66 g cutting-1 plant-1) and estimated leaf yield (4583.04 kg cutting-1 ha-1) were observed to be the highest with application of 30 cm pruning height + 3 months interval of harvest + 0.3% humic acid. The treatment L2P2N4 (30 cm pruning height + 3 months interval of harvest + 0.3% humic acid) registered the highest growth and yield characters of curry leaf.

Effect of pruning season and tool on knot occlusion and stem discolouration in <i>Betula pendula</i> – situation five years after pruning

This paper investigates and models the effects of pruning season and tool on wound occlusion with varying tree and branch characteristics of silver birch (Betula pendula Roth) stems at the pruning height of 0−4 metres. Dates of eight secateurs prunings, three saw prunings and two sticks prunings as well as unpruned control were tested in permanent plots on four sites. Knot occlusion and discolouration in stemwood were measured from about 1600 studied knots of 112 sample trees felled five to six years after pruning in 2010. Knot occlusion rate was modelled according to pruning tool, date, tree growth, and branch characteristics. The occlusion was the fastest in trees pruned in spring or early summer, and the slowest in trees pruned in autumn. Stubs of living branches occluded faster than the dead ones with the same diameter. Saw pruning resulted in clearly better occlusion rates than secateurs pruning, caused by the shorter knot stubs after saw pruning. Hitting dead branches away with a stick resulted in the worst occlusion status. The colour defects spread more often upward from the knot than downward. Discolouration in stemwood was detected more frequently near to the pruned branches than the unpruned ones, and more widely near to the stubs of dead branches than the living ones. Most saw and secateurs pruned branches were completely occluded during the experiment, so these prunings were suitable for all branches under 20 mm in diameter, and for living branches even up to 30 mm in fast-growing trees.

High-pruning of silver birch (Betula pendula Roth): work efficiency as a function of pruning method, pole saw type, slash removal, operator, pruning height and branch characteristics

ABSTRACT The objective of this study was to establish an operational model of work efficiency (net or productive work time per tree) for high-pruning of young silver birch depending on pruning method, pole saw type, operator, pruning height and branch characteristics. The final model included number of branches, cross-sectional area of the thickest branch at the cut, pruning height, pruning method (target or flush pruning) and operator as independent variables. Work time increased with increasing values of each of the three numeric variables. For a given pruning height the number of branches was for all practical purposes more influential than the size of the largest branch. Target pruning was significantly faster than flush pruning, all else being equal. The variation in work efficiency for the five operators in the study spanned a range almost twice as large as that attributed to pruning method. The mean work time for other activities during the pruning operation (supportive work time) was estimated at 17% of the productive work time for pruning.

High-pruning of European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.): work efficiency for target pruning as a function of tree species, pruning height, branch characteristics, pole saw type and operator

ABSTRACTThe objective of this study was to establish an operational model of productive work time per tree (work efficiency) for high-pruning of young European beech and pedunculate oak depending on tree species, pruning height, branch characteristics, pole saw type and operator. The final model included all of these independent variables with branch characteristics specified in terms of number of live branches and cross-sectional area of the thickest branch at the cut. Work time increased with increasing values of each of the three numeric variables. For a given pruning height the size of the largest branch was for all practical purposes more influential than the number of live branches. Beech took 28% longer to prune than oak. The German Ergo-Schnitt saw was 21% slower than the Japanese Silky Hayauchi saw. The variation in worker performance within our study was larger than that attributed to tree species and pruning equipment.

Germplasm evaluation and influence of soil type, plant density and pruning height on biomass yield of moringa in central Vietnam

Moringa (Moringa oleifera Lam.) is a tree species with known value for food, medicine and water treatment. This study was conducted to: 1) evaluate promising moringa accessions from the World Vegetable Center; 2) select accessions adapted to growing conditions in central Vietnam; and 3) determine the influence of soil types, plant density and pruning height on biomass yield of moringa. The results showed that moringa accession VI08718 is the most adapted for growing in central Vietnam. It gained the highest yield (96.1 g plant-1) and highest mean number of branches at each harvest (3.9 branches). Moringa can grow in any soil type but it gained highest yield in alluvial soil (108.0 g plant-1). Biomass yield of moringa grown in sandy soil and fallow sandy soil was lower than in other soil types. However, improvement of sandy soil and fallow sandy soil resulted in high biomass yield comparable to yield in alluvial soil. Plant density of 160,000 plants ha-1 produced the highest yield (8.3 kg plot-1), whereas plants pruned at 55 cm from the soil surface obtained the highest yield (10.3 kg plot-1).

INDUÇÃO DE BROTAÇÕES EPICÓRMICAS POR MEIO DE ANELAMENTO E DECEPA EM ERVA-MATE

A erva-mate (Ilex paraguariensis) é uma espécie arbórea, nativa da América do Sul e largamente consumida na forma de chá. Em ervais debilitados, a poda de recuperação é utilizada para a retomada do vigor vegetativo, bem como o anelamento, os quais estimulam a emissão de brotações. O presente trabalho teve como objetivos verificar a influência do anelamento em combinação com a aplicação de diferentes concentrações de benzil-amino-purina (BAP) e da decepa em diferentes alturas na emissão de brotações por matrizes de erva-mate de 17 e mais de 80 anos de idade, no inverno/2006 e verão/2007. O anelamento foi realizado com motosserra a uma altura de 30 cm do solo, seguido do tratamento com BAP, veiculado em pasta de vaselina, nas concentrações de 0, 150 e 300 mg Kg-1. A decepa foi realizada também com motosserra, sendo os tratamentos três alturas de corte: 15, 30 e 60 cm do solo. Após 6 e 12 meses da instalação foram avaliadas as seguintes variáveis: porcentagem de matrizes brotadas, número de brotações por árvore (ou cepa), comprimento e diâmetro das brotações. Os resultados obtidos mostram que a erva-mate tem boa capacidade de brotação, para as duas técnicas utilizadas. A eficiência na emissão de novos brotos no anelamento é influenciada pela idade da planta matriz e pela estação do ano. Os maiores valores foram obtidos no inverno/2006 e com matrizes de 17 anos de idade, chegando a 95,84% de indução de brotações. Na técnica da decepa, não foi observada influência da época de instalação na porcentagem de brotação, mas a idade da matriz e a altura do corte foram significativos para esta variável. Os maiores valores foram obtidos com matrizes de 17 anos e altura de corte a 60 cm do solo.
