After sowing of cotton, it takes normally 4 to 5 days for the germination. Late germination is harmful to the crop. Therefore, the seeds of cowpea is also sown along with the seeds of cotton crop in the field. The sprout of cowpea comes out of the soil within two days. Then the sprouts of cowpea are removed from the field. As a result, there is quick growth of the cotton crop.
Crop: Cotton
Crop Family: Malvaceae
Crop Scientific Name: (Gossypium spp.)
Crop Vernacular Name: Rui, Tulo, Kapas, Hatti, patti.
Ingredients: seeds of cowpea crop
"The plant growth and boll setting of cotton was much better in the plot treated with ‘bajra’ flour.”

farmers sow one castor seed per hill while dibbling cotton seeds. Castor germinates more or less simultaneously with cotton. The castor seedlings break through the hard soil crust and make way for the cotton seedlings to sprout.”

A cotton crop treated with mepiquat chloride will consistently exhibit shorter internodes, increased leaf thickness, a more compact fruiting zone, and potentially earlier maturity. These changes can enhance harvesting, improve pesticide penetration to lower portions of the plant canopy, and reduce the occurrence of boll rot.”
