| dc.description.abstract | The present investigation was carried out at Horticultural Research Centre, Patharchatta and Department of Horticulture, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, district Udham Singh Nagar (Uttarakhand), India to study the effect of shoot pruning and paclobutrazol on growth, flowering yield and quality of lemon (Citrus limon Burm.)” cv. Pant Lemon-1 during the year 2015 to 2017.The trial was laid out using Randomized block design with three replications. The treatments consist of half shoot pruning at 45 cm intensity and paclobutrazol application @ 2.5 ml/tree in October to April and their combinations in January, February and March and were compared with control. The results revealed that the vegetative growth, flowering, yield and quality were significantly affected by half shoot pruning and paclobutrazol application. The treatment comprising half shoot pruning in October (T1) and application of paclobutrazol in March (T13) were found to more effective in terms of increment in plant height, stem girth plant spread, canopy volume, cross trunk sectional area, number of new shoots, shoot length, leaf area, chlorophyll content of leaves, number of hermaphrodite flowers clusters, total number of flowers clusters, average number of flower per clusters, fruit set, fruit yield distribution, number of fruits, yield kg per tree and fruit yield efficiency. The treatments mentioned above also improved fruit weight, volume, length, diameter, juice content, total soluble solids, TSS: acidity ratio and ascorbic acid. The maximum total net return was obtained with application of paclobutrazol in March (T13). On the basis of the results obtained in the present study, it can be concluded that under Tarai region of Uttarakhand, early half shoot pruning after crop harvesting in lemon cv. Pant Lemon-1 in October-November more effective on improving vegetative growth, flowering, fruiting, yield and quality in spring flush and treatment application of paclobutrazol @2.5 ml/tree in March gave maximum total net return per tree/year. The harvesting period can be shifted early i.e. May-June under Tarai condition of Uttarakhand by proper manipulation of early (October-November) half shoot pruning and application of paclobutrazol in lemon. | en_US |
