Use of Chemical herbicides :- Spray the recommended amount of herbicide in 700-800 liters of water.Use the Flat Fan or Flood Jet Nozzle in the Sprayer. Spray on moisture land.Use only one of the recommended weed chemicals for soybean cultivation. Use every year a diffrent herbicide.

Recommended Dose of Herbicide for Soybean:-

Time of Uses	Chemical Name	Quantity/Hactare
Before sowing	1 Fluchloralin	2.2 Litre
Before sowing	2 Trifluralin	2.0 Litre
After sowing	1 Metolachlor	2 Litre
	2 Clomazone	2 Litre
	3 Pendimethalin	3.25 Litre
	4 Diclosulam	26 Gm
10-15 Days after sowing	1 Chlorimuron ethyl	36 Gm
15-20 Days after sowing	1 Imazathpyr	1 Litre
	2 Quizalofop ethyl	1 Litre
	3 Fenoxaprop ethyl	0.75 Litre
	4 Propaquizafop	0.75 Litre

Soybean Seed Treatment :-Treat the soybean seeds with carboxin 37.5% + Thiram 37.5 WP @ 250 gms per quintal of seed before sowing. or treat the seeds with Carbendazim 12%+ Mancozeb 63% @ 250 gm per quintal of seed or Thiophanate methyl 45%+ Pyraclostrobin 5% FS @ 200 Ml/quintal of Seed. After that treatment treat the seed with Imidacloprid 30.5% SC @ 100 ml/ quintal of seed or Thiamethoxam 30% FS @ 250 Ml/ Quintal of seed gets protection 30 Days from Sucking pest.

Seed rate, sowing time and sowing method of Soybean

06/06/2018

Seed rate, sowing time and sowing method of Soybean:-

Seed Rate:- According to the size of the seeds of different varieties, the seed rate of normal germination capacity should be used as follows:- (1) Small grain size varieties 28 Kg/ Acre. (2) Medium grain size varieties 30-32 Kg/ Acre (3) Big grain size varieties 36 kg/ Acre.

Sowing time:- The best time of sowing is from the first week of June 20 to July, when the rainfall is approximately 3-4 inches, the sowing should start. Short duration varieties should be used in late sowing conditions.

Sowing Method:- Soybean sown should be done in line. Sown the seeds at a depth of 3 – 5 cm adopting a spacing of 45 x 5 cm.

Improved Varieties of Soybean and their selection

05/06/2018 Monday January 18th, 2021

Improved Varieties of Soybean:- Varieties should be selected according to the agro climatic zone. In the light land and rain-fed areas where average rainfall is between 600 to 750 mm. There should be early duration (90-95 days) variety. Medium type loamy land and 750 to 1000 mm in areas with moderate rainfall, in the medium-duration varieties should be used to mature in 100 to 105 days. Late varieties should be sown in areas with excess rainfall from 1250 mm and heavy land. It should be noted that the seed germination capacity is more than 70 percent and the number of plants for the good harvest in the field should be 40 plants per square meter, only the suitable varieties of seed should be selected.

Improved varieties of soybean suitable for Madhya Pradesh.

Manure and fertilizer dose for Soybean

26/05/2018

Manure and fertilizer dose for Soybean:-

Soybean is a pulse and oilseed crop. There is less need of nitrogen. Giving more nitrogen can lead to unfruitfulness, therefore it has to pay special attention to nutrient management.

The quantity of Manure and fertilizers can be distinguished according to the soil test report, location and variety.
Add a well composted FYM to 10 tons per acre at the last ploughing.
By Soybean Research Centre recommended 20: 60: 20: 20 kg per hectare. Nitrogen: Phosphorus: Potash: Sulphur according to which approximately 50 kg DAP per acre, 10 kg single super phosphate and 30 kg potash as a basal dose and After 15 days of sowing, 8 kg per acre sulfur 90% WDG and 4 kg per acre (bio-fertilizer) should be broadcasting.
At the time of sowing it is very beneficial to treat Rhizobium culture with 5 grams per kg of seeds and PSB culture with 5 grams per kg seed.

Management of Mosaic Virus Disease in Sponge Gourd

24/05/2018

Management of Mosaic Virus Disease in Sponge Gourd:-

Symptoms:-

This viral disease is transmitted through sap and vector aphids, white fly and red pumpkin beetle.
In infected plants, the younger leaves unfold very late show complete chlorosis following by green vein banding.
The older leaves exhibit prominent dark green raised blisters. the malformed leaves assume a filiform shape.
Vegetable growth, flowering and productivity are also adversely affected. severely affected vines do not set fruit.

Management:-

Adopt clean cultivation and remove alternate host particularly weeds.
Avoid relay cropping of susceptible crops.
Avoid cropping mosaic prone season and areas.
Spray Dimethoate 30% EC @ 30 Ml./pump at 10-15 days intervals. and add antibiotic chemical like streptomycin 2 gm/pump for better control.

23/05/2018

Management of Leaf Reddening in Cotton:-

Adjustment of sowing time for enabling the crop to skip over the adverse environmental condition during boll development stage.
One or two sprays of urea (1 %) at appropriate times.
Application of magnesium sulphate (0.5%).
Adequate drainage to avoid waterlogging of the fields.
