About RRS, Kakdwip

The Regional Research Station (Coastal Saline Zone) of Bidhan Chandra Krishi Viswavidyalaya (BCKV) is situated at the south-eastern part of the state (22°40´ N latitude, 88°18´ E longitude with 7 m above mean sea level at 35 km away from the Bay of Bengal and besides 117 NH) at Akshaynagar, Kakdwip, South 24-Parganas, West Bengal. Total area of research station is 25 acres. The region belongs to the sub-humid and sub-tropical agro-ecological zone with an average annual rainfall of 1560 mm, 80% of which falls during the rainy season (June−September) due to the southwest monsoon. The soil is having clay in texture and had the following key properties for the 0−30 cm layer: pH 5.84 (in 1:2.5:: Soil : Water), EC 1.55 dS/m (in 1:2.5:: Soil : Water), available N 155.24 kg/ha (Hot alkaline KMnO4 Method), available P 105.76 kg/ha(0.5 M NaHCO3 extract), available K 365.86 kg/ha (Neutral N NH4OAc extract) and available B 2.63 kg/ha (Hot water-CaCl2 extraction).

Annul Progress Report 2023-24

Key research findings of the trials conducted at Regional Research Station (CSZ), BCKV, Kakdwip and other parts of coastal saline zone of West Bengal during last three years (2023, 2024 and 2025)

• Two Indian mustard cultivars namely ‘Kranti’ and ‘TBM 143’ have been found suitable for cultivation in the coastal belt of West Bengal with the application of 150% RDF (120 kg N, 60 kg P2O5 and 60 kg K2O ha-1) for obtaining higher productivity in sole mustard cropping.

• Furrow sowing (at shallow depth, 3-5 cm) and N supply @ 200 kg ha-1 has been proved to be effective for achieving higher productivity, nitrogen balance and economic gain in spring sunflower (var. SUN FARM) cultivation under the coastal agro-ecosystem of West Bengal.

• Seed sowing on November 30 with chemical fertilization of 100% RDF (80 kg N, 40 kg P2O5 and 40 kg K2O ha-1) has been found to be beneficial for productive and profitable sunflower (var. Sunbred 275) cultivation.

• Soil salinity at least upto 4 dS m-1 exerted no deleterious effect on tuber yield and quality characters namely skin colour, flesh colour and tuber appearance for potato cultivars namely Kufri Lima, Kufri Himalini and Kufri Jyoti.

• Application of herbicide GPH 0819b @ 3000 ml ha-1 and 3750 ml ha-1 (being at par with each other) were found safe and most effective in controlling grasses, broad leaved weeds and sedges in cotton in coastal saline belt of West Bengal.

• Application of bio-stimulant (Sosdia Stress) could not increase growth and yield of kharif rice significantly probably because of climatic extremes but its application in maize (Sosdia Stress @ 500 ml ha-1 applied after both V7 and Silking (R1) stage) enhanced growth and seed yield significantly in coastal saline belt of West Bengal.

• Spraying of Gibberellic Acid 0.186% SP @ 88.75g ha-1 at 45 DAS and GA 0.001% L @ 180 ml ha-1 at 45 and 90 DAS in cotton was found to be most effective in improving almost all the growth parameters, yield attributes and seed yield in coastal saline belt of West Bengal.
