Department of Soil Science

About the Department

The Department of Soil Science owes its origin to Imperial Agricultural Research Institute established at Pusa, Bihar in 1905. Workers like Dr. J. W. Leather “considered father of Indian Soil Science & Agricultural Chemistry” sowed the seed for the research in the field of soil science at Pusa. After the establishment of Rajendra Agricultural University in 1970, the post graduate studies in Soil Science started with a full fledged laboratory and staff. Stalwarts like Prof. S. C. Mandal, Dr. K. K. Jha, Dr. P. P. Jha, Dr. M.K. Sinha, Dr. R. Sakal and others gave the present shape to the Department. Further the state university i. e Rajendra Agricultural University has been upgraded in to CAU, Dr. Rajendra Prasad Central Agricultural University and departmental research, teaching and extension activities gained momentum to fulfill the need of farmers, students and researchers.

The department has carved a niche for itself through focused research in different spheres of soil science as well as by producing quality human resource through excellent postgraduate with updated and modern courses curricula. The great diversity in the areas of expertise and interests present in the Department leads to diversity in thesis research. Till date about 202 M.Sc. and 57 Ph.D. students have earned degrees and more than 1200 research publications have been made.  

Over the years, the trained and accomplished faculty members as well as students in addressing current issues in Soil Science have won several national and international awards. Individual staff members within the department have long been recognized for their leadership role in the Soil Science. To cater the needs of farmers, the soil testing lab is issuing Soil Health Card with crop based nutrient recommendation.

Extension Activities:

Scientists of the Department has actively participated in development of Sukhet Model (Dr. Shankar Jha, Dr. M. C. Manna and Dr. S. P. Singh) which was highly appreciated by Hon,ble Prime Minister Govt. of India in 80th episode of Man Ki Baat on 29th August,2021.

Glimpses of Sukhet Model in Hon’ble Prime Minister’s Mann Ki Baat

“Before me is an example that has come from Madhubani in Bihar. Dr. Rajendra Prasad Central Agricultural University in Madhubani and the local Krishi Vigyan Kendra have jointly made a worthy effort. Not only farmers are accruing benefit from this scheme but it has also imparted renewed vigour to the Swachh Bharat Abhiyan. The name of this initiative of the University is – “Sukhet Model”. The purpose of the Sukhet model is to reduce pollution in the villages. Under this model, dung and other household wastes are collected from the farmers of the village and in return the villagers are given money for cooking gas cylinders. The process of making vermicompost from the village’s discarded trash is also underway. Therefore, there are four benefits of the Sukhet model that are directly visible. First, the village is freed from pollution; the second is that the village is freed from filth; the third is that the money for the LPG cylinder goes to the villagers and the fourth is that the farmers of the village get bio- fertilizer. You must give it a thought as to how such efforts can increase the power of our villages. This is the basis of self-reliance. I appeal that every Panchayat of the country should also think of doing something like this in their respective villages.”

Dissemination of Vermicomposting technology: Semi-automated vermicompost technology has been demonstrated in a large scale at Babadham temple of Deoghar and DRPCAU, Samastipur. This low cost technology is most suitable for recycling of domestic kitchen waste, horticultural waste, temple flower offering waste

  1. Sanitation of Bareja
  2. Drenching of Bordeaux Mixture (1%) after onset of Monsoon followed by soil application of bio-agent –Trichoderma viride incubated in MOC(5kg TV/500kg/.ha) and one more drenching of Bordeaux Mixture (1%) after 60 days of 1st drenching

The most effective treatment for management of citrus canker was combined application of Copper oxychloride (CoC) @ 3g per litre+ Streptocycline @ 0.3 g per litre which showed least lesion/leaf i.e.8.20 lesion/leaf. This was followed by spraying of Copper oxychloride (CoC)@3g per litre showing 15.75 lesions per leaf which was statistically at par with treatment of 2% Neem seed kernel extract as spray which exhibited 18.75 lesions per leaf.

The treatment involving disease-free suckers from a disease-free field + dipping in carbendazim (0.2%) for 45 minutes followed by carbendazim drenching (0.2%) and carbendazim injection @ 3 ml of 2% solution during the 3rd, 5th and 7th month after planting (MAP) was found to be effective (wilt incidence of 6% as against 80.33% in control) in reducing wilt incidence.However, bio-control agents i.e. Trichoderma viride (@ 10g/sucker three times) used as soil application also found highly effective and causes marked suppression of Panama wilt so may be included in integrated crop management (ICM)/ integrated diseases management (IDM) schedule in strict organic system.

  • Seed treatment with  Pseudomonas talc formulation @ 0.40% followed by its foliar spray @40% at 45, 60 & 75 day after sowing can be recommended to manage stem gall disease of coriander caused by Protomyces macrospours.
  • Alternatively, seed treatment with Hexaconazole @0.20% followed by its foliar spray @0.20% at 45, 60 & 75 day after sowing can be recommended to manage stem gall disease of coriander caused by Protomyces macrosporus.

Seed treatment with Propiconazole @ 0.1% followed by its foliar spray @0.1% at flower initiation stage can be recommended to manage Alternaria blight (Alternaria brassicae) disease of mustard.
