Produksi buah jambu biji ( Psidium guajava ) yang bersifat musiman memerlukan teknik pengaturan pembungaan agar dapat tersedia sepanjang tahun. Sarkar A, Ghosh B, Kundu S and Sukul P (2005). The results of the present investigation indicated that, different pruning treatments and fertilizer levels produced significant effect on fruit quality of guava. The increase of growth, production, and quality of 'Crystal' guava can be done by pruning. Guava is a popular tropical fruit tree. Current study was undertaken to highlight the effect of pruning on improving vigor of old orchards and increasing performance in terms of fruit yield and quality under water and nutrient stressed condition of mid hills of Eastern Himalaya. An increase in the total num, dominance due to pruning, thus inducing the g, Nevertheless, there is no difference in the number of generative and, significant between the application tim, number of productive branches, the higher amount o. in mangosteen, tangerine [9] and pamelo citrus [10]. Large trees take several years before they come into bearing and overall cost of production per unit area is further increased. Thinning helps counteract the tree’s dense growth to let light and air in to the inner branches, which helps them stay healthy and … The results of this study indicate that the dosage of straw compost has a very significant effect on the fruit diameter and has a significant effect on the weight per cucumber fruit. 2019 to study the effect of pruning intensity and time on yield and quality of winter guava Kata kunci: cooling chamber, citrus color index, jeruk tropika, karotenoid, klorofil ABSTRACT The minimum flowering (232.80) was recorded in M 3 (Pruning of 30th May )guava trees. Canopy pruning is one of the techniques for regulating plant growth. Maximum PME activity was found in L-49 (56.25 units/g.f.wt) at HRS whereas, it showed a decrease at FRS (52.25 units/g fresh weight (FW) followed by Allahabad Safeda and Lalit. Branches that are touching … It has no major pest or disease problems. In this paper, we discuss the role of this enhanced light interception by the canopy in increasing the autonomy of the fruiting shoot, i.e. Compared to the solaxe system, centrifugal training significantly improved the STAR of the whole tree by 20%. The effect of three pruning intensities on guava was not detected in 1989. Fruit weight and internal fruit quality were not affected by pruning. Pruning applied in May had the highest, allocation of carbohydrates from source to sink, reduced, the sink organ in the form of fruit g. determine the quality of fruit flavor.

Degreening did not give negative impact on i nternal quality. Ethylene 0, 100, 200 ppm was injected into the box containing 2.8 kg citrus and was exposed to the cooling chamber with a temperature 18 ⁰C for 24 hours ethylene + 48 hours without ethylene, 48 hours ethylene + 24 hour without ethylene and 72 hours ethylene. Lucknow-49 was undertaken at Horticultural College and Research Institute, Periyakulam during 2016-2017.The experiment consists of seven different levels of pruning and growth regulator application and the treatments were imposed on two years old trees. Hasil penelitian menunjukkan bahwa jumlah bunga tertinggi diperoleh pada perlakuan pemangkasan bentuk V (V), yaitu 85,30%, jumlah buah tertinggi pada perlakuan pemangkasan bentuk V (V) dan perlakuan pemangkasan samping (S) masing-masing sebesar 208,8 buah/pohon dan 201 buah/pohon. The experiment was conducted to study the interaction effect of pruning and organic manure on rainy and winter season crop of guava. improved fruit size and colour, and return-bloom. In contrast, ASE lowered (P < 0.001) spur density (S=4.5) but increased (P < 0.01) that of annual shoots (T=3.6; S+T=8.1). It also improved the fruit The results of the present study revealed that with the advancement of fruit maturity at different stages, the total soluble solids (TSS), sugar (total sugars, reducing and non-reducing sugar), ascorbic acid contents increased significantly while, during fruit ripening acidity and pectin decreased. Thus, we applied artificial spur extinction (ASE) in spring to reduce floral bud numbers of three-year-old. Effect of time and severity of pruning on growth and yield of guava (Psidium guajava L.) cv. Recently, centrifugal training, i.e. The failure to manipulate the production periods is a common problem for guava production in Improvement of light penetration within tree canopies has been a constant objective of fruit tree architecture manipulation through the setting up of training systems. Abstract . accordance with the research conducted by [4] on red getas guava (getas merah guava) plants. Jurnal Pengkajian dan Pengembangan Teknologi Pertanian, flowering and harvesting of guava cv 'Krystal'. Enviro Eco 3: 621-623. The study was undertaken in seven guava (Psidium guajava L.) cultivars at three different developmental stages, viz. One ofsimplestcultivationtechniquestoimprovethe yieldofCrystalguavaispruning. Series, treatment can accelerate the time the flower appears 10 d. Pruning is required to stimulate the growth of productive shoots and eliminate unproductive shoots, therefore the management of pruning needs to be, resulted in the appearance of new buds and flowers so. Different pruning application time does not, although the pruning in May tends to show. The seasonal production of guava ( Psidium guajava ) requires flowering manipulation technique such strangulation in order to be available throughout the years. Prune the tree lightly in the summer after harvesting the fruit. Pectin methyl esterase (PME) activity increased progressively in all the cultivars up to HRS and subsequently decreased at FRS. In addition to preventing a biennial pattern of bearing, ASE increased red blush coverage around the surface of the fruit skin by 6-7%, enabled a greater proportion of crop to be colour-picked in the first and/or second commercial harvests, and increased fruit dry matter content. The present studies on crop regulation in guava (Psidium guajava) cv. This research was aimed to examine the effect of canopy pruning on productivity and fruit quality of mandarin cv Pulung. Guava tree care is simple and easy and with a few basic information, you can grow a healthy plant. It does well with minimal pruning and care and typically won't require much irrigation beyond normal rainfall. Mehta et al. ThisneedstoImprove ofcultivationtechniquesformeetthe needsoffreshguava.
