Seed quality is one of the most important factors for stand establishment in cotton (Gossypium Sp.), and the use of good quality seeds is therefore essential to obtain an optimum plant population. Conditions prevailing during seed formation can affect the quality of seed produced, and hence crop establishment in the next growing season. These conditions can affect the germination of the seeds and the ability of the seedlings to emerge from soil. Field experiments were conducted to investigate the effect of nitrogen (N), phosphorus (P), potassium (K), foliar application of zinc (Zn) and...

This study investigates the statistical relationship between climatic variables and aspects of cotton production, and the effects of climatic factors prevailing prior to flowering or subsequent to boll setting on flower and boll production and retention in cotton. Also, predicted effects of climatic factors during convenient intervals (in days)on cotton flower and boll production compared with daily observations. Further, provide information on flower and boll production as affected by climatic factors and soil moisture status.

Hydroponics is one of the many methods of soilless agriculture through which plants are grown using mineral nutrient solutions in water, without soil. Many commodity crops like tomatoes, Strawberry, Cucumber, onions, lettuce and cabbage have been successfully cultivated through hydroponics, and their produce well-accepted in many markets. The theory behind the method is that the soil is only a mineral nutrient reservoir and hence, it is not very essential to plant growth. The mineral nutrient can be introduced into a plant's water supply artificially which is then readily absorbed by the...
