Wheat Research Station

Junagadh Agricultural University
Junagadh-362 001 Gujarat (India)

Year of Establishment :

Wheat Research Station, J.A.U., Junagadh was established in the year 1960 with the approval of the Wheat Research Scheme by the Government of Gujarat. The centre is representing the whole Saurashtra region i.e. seven districts viz. Junagadh, Jamnagar, Rajkot, Amreli, Bhavnagar, Surendranagar and Porbandar of Gujarat state. The main objectives of this station are to develop high yielding, dwarf, high fertilizer responsive, disease resistant wheat varieties with better grain quality of bread and macaroni durum wheat for different production conditions. Simultaneously, the research work on new production technology and plant protection technologies for the newly released varieties of wheat for this area is also conducted regularly. This station was strengthened by sanctioning of the scheme "All India Coordinated Wheat Improvement Project" by Indian Council of Agricultural Research, New Delhi from 09/07/1987. This provides an ample scope for testing newly developed varieties under wide range of environmental conditions. Further, this station has been strengthened by sanctioning of the plan scheme entitled "Strengthening Research in Wheat" by State government under 11^th five-year plan from 2008. The main objective of this scheme is to generate high temperature tolerant genotypes of T. aestivum and T. durum wheat suitable for early sowing.

Introduction :

Junagadh is a main wheat research station of Junagadh Agricultural University located in Saurashtra region and sub-centre for Gujarat state. The climatic conditions of the station represent the tropical-subtropical climates characterized by fairly cold, dry and short winter, hot and dry summer and comparatively low precipitation during monsoon season. This station is also working as a Regional Research Station of Central Zone for wheat crop.

Mandate :

Testing of various national/international nurseries and selection of better genotypes for utilization in hybridization programme.
Development of new crosses and growing various segregating generations for selection of better individual plants in aestivum and durum wheat.
Testing of various genotypes developed at this station and conduct different experiments for their performance in the zone
Screening wheat genotypes for their reaction against the brown and black rusts.
Productivity enhancement and maintenance through developing varieties tolerant to various biotic and abiotic stresses by adopting intensive hybridization programme.
Monitoring of wheat diseases and pests in the Saurashtra region of the state. Breeder seed production programme of recommended varieties of wheat.

Objectives :

Collection, evaluation, characterization and conservation of wheat germplasm and wheat biodiversity.
Developing variety with high yield potential, better quality and resistance to biotic and abiotic stresses.
Developing efficient eco-friendly techniques for achieving high production, productivity and conservation of natural resources.
Evolving better and efficient management system for management of pests and diseases.
Nucleus and breeder seed production and advisory services.

Thrust areas :

In Saurashtra region, winter is very short. To compensate winter spell and crop growth stage, the sowing time of wheat is recommended during the second week of November. However, the farmers of this region generally prefer early sowing because of shortage of irrigation water at the ripening stage of wheat i.e. during February-March. Such practice greatly affects the initial growth and ultimately results in poor yield. Under these situations, the development of early heat tolerant, early to medium maturing and rust resistant varieties is highly required. Likewise, durum wheat produced in Saurashtra region possesses superior grain quality but farmers are reluctant to accept the durum wheat because of longer maturity period than bread wheat. Keeping these facts in view, the further research work should be aimed at :

Enhancing productivity and profitability of wheat by developing varieties with higher yield through incorporation of genes from different sources.
Continuously updating the tolerance against biotic and abiotic stress through incorporation of resistance genes from various germplasm sources.
Development of high yielding and early maturing varieties suitable for early sowing especially in Saurashtra region
Development of varieties suitable for restricted irrigations.
Collection, evaluation and maintenance of germplasm and elite breeding materials for crop improvement.
Development of facilities for the creation of artificial epiphytotic conditions for different races of black and brown rusts of wheat in order to screen large number of entries
Technology development for higher production based on integrated nutrient management, efficient water management and improving tillage technology and post harvest care

Agronomy: The following crop production technologies recommendations were made by this station.

1. Sowing time of wheat is very important and it affects the grain yield to great extent in this area. Middle of November is recommended for sowing of wheat in Saurashtra region to obtain maximum yield.

2. The results of an experiment on nitrogen and phosphorus requirements indicated that wheat crop required 120 kg nitrogen and 60 kg phosphorus. It is recommended to apply half dose of N and full doze of P2O5 at the time of sowing and remaining half doze of N at 21 days after sowing

3. To control the weeds in irrigated wheat, Pendimethalin should be sprayed @ 1 kg a.i./ha as pre- emergence application.

4. The farmers of South Saurashtra agro-climatic zone following groundnut- wheat crop sequence are advised to apply FYM 15 t/ha to kharif groundnut followed by 120 kg N and 60 kg P2O5/ha to wheat for getting higher yield and economic returns.

5. In the areas of South Saurashtra Zone where irrigation water is not a limiting factor, farmers are advised to irrigate (50 mm) the wheat crop at weekly interval (Total 14 irrigations) in order to get maximum yield and net return. However, on the basis of net ICBR, ten irrigations are recommended. The first irrigation should be given immediately after sowing of seeds in dry soil followed by next irrigation at 6 days after sowing for better germination. The rest of the irrigations should be given at an interval of 8 to 10 days.

6. The farmers of South Saurashtra Agro Climatic zone growing wheat in medium blacl calcarious soil are recommended to spray multi micro nutrient formulation Grade 4 @ 1% (three sprays 30,45, and 60 DAS) or application of micro nutrients as per soil test value in addition to recommended dose of fertilizer (120-60-00 N-P2O5-K2O Kg/ha) for getting higher yield and net returns.(2012 in collaboration with Department of Soil Science and Chemistry.)

7. The farmers of South Saurashtra Agro Climatic zone growing wheat under irrigated condition are advised to spray growth promoter Brassinolide (BS) @ 0.01 mg/L at milk-dough stage to obtain higher grain yield and net return.(2015 in collaboration with Department of Genetics and Plant Breeding)

8. The farmers of South Saurashtra Agro Climatic zone growing wheat are advised to apply 60 Kg Potash and 40 Kg Sulphur (in form of phosphor gypsum) per hectare as basal and ecommended dose of N and P (120-60 N-P2O5 Kg/ha) to wheat crop for getting maximum yield and return.(2016 in collaboration with Department of Soil Science and Chemistry).

9. The farmers of South Saurashtra Agro-climatic Zone growing wheat in medium black calcareous soil are recommended to apply nitrogen @ 120 kg/ha in three splits (¼ as basal + ½ at 20 to 25 DAS + ¼ at 35 to 40 DAS) instead of two splits in addition to recommended dose of P2O5- K2O (60-60 kg ha-1) for getting higher yield, net return and improve nutrient use efficiency.

10. The farmers of South Saurashtra Agro-climatic Zone growing wheat are recommended to adopt drip irrigation at 0.8 Etc in flat bed for acquiring higher yield, higher net return and save irrigation water over broad bed furrow and flood irrigation.

Drip irrigation system details are as under
