Abstract/ Executive Summary:

A study was conducted at Citrus Research Station (CRS), Jaintapur, Sylhet started in 2015-2016 to see the performance of BARI Malta-1 using six citrus rootstocks viz., pummelo, sweet orange (BARI Malta-1), deciber(CS Jai-001), sweet lime, rough lemon and karun jamir. Highest plant height was recorded in sweet lime rootstock (210.33 cm) followed by rough lemon (183 cm) whereas lowest was found in sweet orange rootstock (168 cm). Maximum base girth was found in rough lemon rootstock (17.67 cm) followed by pummelo rootstock (17 cm) whereas minimum in deciber and karun jamir rootstock (11.67 cm). Plant canopy was recorded highest in rough lemon rootstock (149.67×153 cm) while lowest in deciber rootstock (91×88.67 cm). Results of one successive years of investigation revealed that rough lemon rootstock exhibited excellent growth condition whereas poor growth was found in deciber rootstock.

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Sweet orange

Objectives:

To select suitable rootstock(s) for sweet orange var. BARI Malta-1.

Methodology:

Six different types of rootstocks viz pummelo, sweet orange, sweet lime, deciber (CS Jai-001), rough lemon and karun Jamir (sour orange) were used as treatment and BARI Malta-1 was grafted on them. The graftages were planted in the experimental plot on June, 2016 with a spacing of 3×4 m. Each plant was fertilized with 15 kg cow dung, 200 g urea, 150 g TSP and 100 g MoP in two splits before and after rainy season (Mandol et al., 2014). The saplings were irrigated at an interval of 15 days. Cypermethrin (Ripcord 1.0 ml/L of water) was applied to reduce lemon butterfly infestation when new leaf emerged. Weeding was done after 7 to 10 days intervals, because rapid growth of weeds due to high rainfall in the region. Data were recorded on plant height, base girth, canopy spreading, number of branches/plant, leaf size and growth condition and analyzed by MSTST-C programme. DMRT was performed for interpretation of results (Gomez and Gomez, 1984).

Achievement/Findings:

Maximum base girth was found in rough lemon rootstock (17.67 cm) followed by pummelo rootstock (17 cm) whereas minimum in deciber and karun jamir rootstock (11.67 cm). Plant canopy was recorded highest in rough lemon rootstock (149.67×153 cm) while lowest in deciber rootstock (91×88.67 cm). Results of one successive years of investigation revealed that rough lemon rootstock exhibited excellent growth condition whereas poor growth was found in deciber rootstock. This is the year performance results. Final conclusion will be made after completion of three fruiting seasons.
