Land preparation
Among 42.5 acres of leased out land at BNCA, 13.5 acres of land allotted at Horticulture farm, BNCA was cleaned and levelled primarily for the plantation of citrus. Considerable vegetation and nearly 75-80 oil palm trees were uprooted and land was cleaned and levelled manually, tractor drawn implements and JCB in the month of April, 2017.
Layout of land
About 4 hectares land was marked for conducting experimental trials at RRCC in the month of May, 2017. The land was mainly divided to four blocks (raised bed, flat bed, rootstock and germplasm).
Establishment of raised beds
A total of 18 raised beds have been established in 50x50 m block during May and June, 2017 for planting of different citrus spp. to evaluate their performance.
Pit making and pit filling
Pits of size 1.5x1.5 ft and 1.5ft deep were prepared on both raised beds and flat bed July, 2017. Pits were filled with vermicompost and top soil (1:1 ratio). About 500g Single Super Phosphate to provide phosphorus to growing plants and chlorpyriphos powder (100g) against termites were added to soil while filling pits. Pits were marked with bamboo pegs.
Planting
Planting of different species of citrus was done in August, 2017. Total 12 spp. of citrus were planted (16 plants each) at 5x3 m spacing on both raised and flatbed system. Further, 41 citrus germplasm accessions were also planted at the farm.
Nutrient management
Nutrients were supplied to the plants through the application of Urea, DAP, MOP at regular intervals for better growth of plants. Further, micronutrients like Zn, Mn, B, and Fe were supplied as a foliar spray to the new flush. Neem cake was also applied (@100g/plant) to the plants.
Irrigation management
The irrigation operations were carried manually at regular intervals for better growth of plants.
Weed management
Weed management was carried manually and occasionally, glyphosate (4l/ha) was applied to kill broadleaf weeds and grasses.
Pest and disease management
Incidence of citrus leaf miner, citrus butterfly, citrus psylla, citrus aphid, citrus looper, and citrus mealy bug were reported (Fig. 1). For the control of these pests’ insecticides, viz., acephate 75 SP @ 1.5g/l and thiomethoxam @0.3gm/l were applied. In addition, COC paste was applied to plant stem up to one foot from ground in January, 2018.
