Pruning for crop regulation in high density guava (Psidium guajava L.) plantation

Abstract

High density management and crop regulation are two important aspects in guava (Psidium guajava L.) production. Therefore, to find out the economic way of managing high density planting and crop regulation, the present work was carried out on 6-year-old guava trees of cv. Pant Prabhat under double-hedge row system of planting during 2009-10 and 2010-11. Seven different forms of pruning [FBT: flower bud thinning by hand, FBTT: flower bud thinning by hand followed by removal of terminal one leaf pair, RLFO: removal of leaves and flower buds by hand, retaining one leaf pair at the top, RLF: removal of all leaves and flowers by hand, OLPS: one leaf pair shoot pruning, FSP: full shoot pruning, OLPF: one leaf pair pruning of fruited shoots only] were studied along with control (C).Minimum annual increase in tree volume (6.764 m3) was recorded with the treatment OLPF, which was 2.31 times less than the control (15.682 m3). Highest yield during winter season (55.30 kg/tree) and total yield (59.87 kg/tree) was obtained from treatment OLPF. One leaf pair pruning of fruited shoots only (OLPF) was also found profitable among other treatments by recording cost:benefit ratio of 1:2.96. This treatment also recorded the highest return distributed in rainy as well as in winter season. On the basis of findings it can be concluded that one leaf pair pruning of fruited shoots only is suitable for profitable high density management as well as crop regulation of guava in farmer friendly manner.

Effect of Pruning Intensities and Fruit Load on Yield and Quality of Guava under High Density Planting System

“…Owing to high leaf to fruit ratio and availability of more photosynthates due to removal of current season"s growth, the fruits gained larger size and weight compared to those from unpruned trees. Similar, results were noticed by Madhubala Thakre et al, (2016) andPatel et al, (2014) in Guava.…”

“…Severely pruned trees there were fewer number of new shoots per pruned shoot. As the number of new shoots per pruned shoot was reduced with increase in the severity in Guava (Madhubala Thakre et al, 2016), in phalsa (Naram naidu, 1987 and in apple (Gardener et al, 1922). It might be due to less number of vegetative buds left on the severe pruned shoot.…”

“…Madhubala Thakre et al, (2016) opined that sink strength (Guava fruit) is the ability to attract metabolite from different sources and decides the direction of flow of photoassimilates. Sink strength determined by the growth rate (sink activity) and the size of the sinks.…”

A Review on Recent Advances in Enhancing the Productivity of Guava (Psidium guajava L.) through Hi-Tech Practices

“…Guava flowers are always borne on newly emerging vegetative shoots; irrespective of the time of years, shoot pruning have been reported to be successful. Shoot pruning is helpful in reducing the tree size and improving the fruit quality (Singh and Bal, 2006, Dhaliwal and Singh, 2004, Kumar and Mishra, 2010, Tiwari and Lal, 2007, Sharma et al, 2013, Prakash et al, 2012, Thakre et al, 2013, Pratibha and Lal, 2013, Thakre et al, 2016, Joshi et al, 2016, Salah, 2005. The time and intensity of pruning affected tree sprout and yield guava cv.…”

Consumer Preference Study on Myrtaceae Fruit Collection of Bogor Botanic Gardens

“…The availability of these fruits complements various types of fruit consumption in traditional and modern markets (Altendorf, 2019). Several types of Myrtaceae fruits can produce the fruits throughout the year without being influenced by the season providing good cultivation management, such as guava (Thakre et al, 2016). This is one of the advantages in developing the Myrtaceae fruits as a potential new consumption fruits.…”
