About Department

Department of Soil Science and Agricultural Chemistry was established in the year 1969 with the formation of Punjabrao Krishi Vidyapeeth on 20th October, 1969, then renamed as Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola on 17th April, 1992. The department was established to cater the needs of teaching, research and extension in the field of Soil Science and Agricultural Chemistry. The educational programmes leading to M.Sc. (Agri.) and Ph. D. in Soil Science and Agricultural Chemistry and Land Resource Management along with various research programmes and allied extension activities are conducted successfully.

The department has total intake capacity of 20 M.Sc. and two Ph.D. students in Soil Science and Agril. Chemistry and six M.Sc. and two Ph.D. students in Soil Science and Agril. Chemistry with specialization in Land Resource Management every year. The Center for Post Graduate Education and Research in Land Resource Management was established in the department in the year 1987 in collaboration with National Bureau of Soil Survey and Land Use Planning (ICAR), Nagpur. The main objective of the Center of Land Resource Management is to identify, generate and correlate the data required for land resource management for optimum utilization of limited land resources.

Recommendation

Long term nutrient management for sustaining soil quality and crop productivity in sorghum – wheat cropping sequence

In sorghum- wheat cropping sequence, on the basis of 20 years results of long term fertilizer experiment, for sustaining soil quality and crop productivity application of recommended dose of fertilizer along with FYM @ 10 t ha-1 is recommended.

Integrated nutrient management for sustaining soil fertility and crop productivity in sorghum – wheat cropping sequence

On Vertisol under sorghum-wheat sequence for obtaining maximum yield of sorghum and wheat and to maintain soil fertility status of soil for longer period, a dose of 100: 50: 40 kg NPK ha-1 + FYM @ 10 t ha-1 to sorghum and 120 : 60 : 60 kg NPK ha-1 to wheat (irrigated) is recommended

Long term nutrient management in soybean – wheat cropping sequence

For sustaining the productivity and fertility of soils under soybean – wheat sequence, it is recommended that 50% N through organic materials and remaining 50% N through chemical fertilizer alongwith 20 kg sulphur and 2.5 kg Zn ha-1 to soybean and recommended dose of fertilizer should be applied to wheat.

Sulphur management in crop production(Soybean and wheat)

It is recommended that 20 kg sulphur through gypsum should be applied for obtaining maximum yield and higher B : C ratio under soybean – wheat sequence on sulphur deficient soil.

 

For maintaining soil fertility and obtaining maximum yield of pigeon pea on sulphur deficient soil, application of 20 kg sulphur ha-1 is recommended with 25 kg N and 50 kg P2O5

Integrated nutrient management in rainfed cotton

For cotton under rainfed conditions 50% recommended dose of fertilizer ( 25 kg N + 12.5 kg P ha-1 ) in combination with FYM @ 5 t ha-1 or application of green loppings of glyricidia at 30 DAS should be applied for getting higher B : C ratio and improvement in soil physical and chemical properties

Nutrient management in cotton through drip irrigation System

It is recommended that the dose of fertilizer can be reduced to 50% recommended dose of fertilizers through fertigation to cotton for achieving the yields comparable with 100% recommended dose of fertilizer through conventional method (soil application).

Integrated nutrient management in oilseeds

Application of 15 t FYM ha-1 + 40:60:40 kg NPK ha-1 + 25 kg sulphur through gypsum should be applied + spraying of 0.2% borax during flowering for obtaining maximum yield of sunflower

 

Spraying of urea @ 2% at 50 and 70 DAS along with recommended dose of NPK (soil application) is beneficial for obtaining maximum yield of soybean

Micronutrient management in crop production in Soybean, Cotton and Mustard

It is recommended that soybean seeds should be treated with Rhizobium + PSB (each 25 g kg-1 seed) and 4 g ammonium molybdate per kg seed alongwith recommended dose of chemical fertilizers.

 

For cotton crop, critical limit of iron in soil and in plant (fully mature leaves) is recommended as 4.5 ppm for soil and 281 ppm for plant.

 

For obtaining maximum yield and higher B:C ratio of soybean- mustard cropping sequence, on zinc deficient soil under 3 t FYM ha-1 + ½ recommended dose of chemical fertilizers (15:37.5 kg N & P) + 10 kg ZnSO4 with Rhizobium and PSB should be applied for soybean and 50 kg N + 20 kg P ha-1 + PSB should be applied for mustard

Soil, Nutrient and Moisture conservation through land management (Cotton and Greengram )

Deep ploughing once in two years is recommended for reducing the loss of soil, water and nutrients from 1.5% sloppy deep black soils.

Soil, Nutrient and Moisture conservation through contour cultivation and live hedgerows (Sorghum and Cotton )

Application of 50% RDF + FYM @ 10 t ha-1 with contour cultivation alongwith established vetiver or leucaena hedge rows is recommended to cotton-sorghum rotation grown on Vertisols for obtaining higher monetary returns and reduction of surface runoff and losses of soil and nutrients.

Management of salt affected soils of Purna valley (Cotton and greengram )

Broadcasting of gypsum in powder form @ 2.5 t ha-1 (50% GR) + 5 t FYM or 2.5 t pressmud cake ha-1 before sowing of crop is recommended for increasing the productivity of cotton, sorghum and green gram as well as improving the physico – chemical characteristics of sodic soils of Purna valley.

 

Application of 2.5 t gypsum ha-1 before sowing and opening of deep furrows after two rows of crops at 30 DAS, is beneficial for reducing the sodicity of soil.

 

Application of 2.5 t gypsum ha-1 once in two years is recommended for improving the physico-chemical characteristics of Purna valley soils

Management of salt affected soils of Purna valley by irrigation and crop residue application (Cotton and Greengram)

It is recommended to incorporate gypsum @ 25% GR (1.25 t ha-1) in soil and pass the alkali water through gypsum bed of 30 cm thickness for getting higher yield of irrigated cotton and B:C ratio and for improving soil characteristics of sodic Vertisols of Purna valley.

Construct a chimany in the centre (0.30 m x 0.30 m x 1.37 m) with small opening for air circulation.

Fill a pit with 15 cm layer of organic waste.

Spread the 90 lit. cow dung slurry on each layer

Fill the pit upto 30 cm above the ground level

Cover the pit with cow dung + soil slurry

Compost will be ready within 120-150 days

Nutrient management in rice in eastern Vidarbha zone (Paddy)

For rice on medium soil in eastern Vidarbha region for obtaining maximum yield and higher B : C ratio, a fertilizer dose of 125 : 62.5 : 62.5 kg NPK ha-1 through chemical fertilizer should be applied.

 

For obtaining maximum yield and higher B : C ratio of kharif rice crop, recommended dose of P and K during transplanting and 25% N through glyricidia and 75% N through urea is recommended.

 

In eastern Vidarbha region for maximum yield and higher B : C ratio in rice and improving characteristics of soil, 5 t biogas slurry ha-1 should be applied with 50% recommended dose of fertilizer (47 : 23 : 25 kg NPK ha-1 ).
