Cotton Research Station
Junagadh Agricultural University
Junagadh-362 001 (Gujarat)

(Year of Establishment : 1962)
Cotton is an important cash crop next to groundnut. Gujarat is the single largest cotton producer state with 36 per cent (101 lakh bales) of the total national production from the area about 25.00 lakh hectares. Saurashtra account 65 % area of the state and contributes 68 % in the total production of the state. Average lint production of the Saurashtra is 754 kg/ha as against 615 kg/ha of the state (2007-08). Among the different districts of Gujarat, Surendranagar ranks first in total cotton production of the state (22 %), followed by Rajkot (16.6 %), Bhavnagar (15.8 %), Vadodara (7.7 %) and Amreli (7.2 %). Thus cotton is very important crop of the Saurashtra region for sustainable agricultural production.
Department Overview :
Regional Cotton Research Station was established in the year 1962 where, research on extra long staple cotton (G. hirsutum) was initiated with help of  I.C.C. Further development of station was done with the help of I.C.A.R. (Indian Council of Agricultural Research) during 1967 through sanction of “All India Co-ordinated Cotton Improvement Project” (AICCIP, B.H. 2009) Where initial project has been merged with new project. Since research on plant improvement, Agronomical practices, Entomological and Plant Pathological aspect on cotton is under progress.
Moreover, considering needs of farmer of Gujarat for pure seed (higher stage) of cotton varieties, Gujarat Government has strengthened the station by approval of project for production of nucleus, breeder and foundation seeds of cotton. Further improvement of station is made by provision of required contingencies expenditure under the scheme “To Establish a Center of Excellence for Cotton Research (B.H. 10009)” at Junagadh in 1980.
As more and more GM (Genetically Modified) crops are being released for field testing and commercialisation. India has a well defined regulatory mechanism for development and evaluation of genetically modified organisms (GMOs) including GM crops and the products thereof. Bt cotton the first GM crop being commercially cultivated in India. Therefore, “Strengthening of Research on Genetically Modified Cotton at Junagadh (B.H. 10582)” is sanctioned by Govt. of Gujarat in the year 2008.
For the enhancement of quality line production for expert purpose and considering the need of textile industries and cultivars, cotton research must be started in Surendranagar district for future demand. Also a slogan was given by our Hon'ble chief minister as " Farm to Fabric, Fabric to Fashion, Fashion to Foreign". Therefore, "Establishment of Bt cotton research centre at Kukada(Surendranagar district)" B.H. 10590 is sanctioned by Govt. of Gujarat in the year 2010

Plant Pathology :

  1. Delinting seed with sulphuric acid @100ml/kg seed and seed dressing with mercuric fungicides 22-3 g/kg seed has been recommended to control seed borne diseases of cotton (RS, Cotton, Surat).
  2. For the control of Alternaria leaf spot of cotton, four sprays of Captafol (Difoltan 0.2%) at an interval of 20 days starting from just after appearance of disease is practicable and economically beneficial (Pathology Dept.,Anand,1978).
  3. Following cultural practices have been found beneficial for reducing the intensity of soil borne diseases like wilt and root rot of cotton (RS, Cotton, Surat).

This is due to high chlorophyll content, increase in plant height, thickness of leaves, and length of sympodia, no. of squares and no. of bolls (2013-14).
  2. The farmers of South Saurashtra Agro-climatic Zone growing Bt cotton under irrigated condition are advised to spray growth inhibitor Cycocel / Chlormequat Chloride (CCC) @ 40 ppm at 90 DAS (0.4g / 10 lit. water) for minimize buds and bolls shedding to obtained higher seed cotton yield and net return. This is due to high chlorophyll content, increase in thickness of leaves, no.of squares, no.of bolls and minimum buds and bolls shedding (2013-14).
