Bean and chia development in accordance with fertilization management

Area of Science:

• Agronomy
• Soil Science
• Plant Nutrition

Background:

• Chia (Salvia hispanica L.) is gaining market popularity, yet its response to residual fertilization from preceding crops is understudied.
• Understanding crop residue effects is crucial for sustainable agricultural practices and optimizing nutrient management.

Purpose of the Study:

• To assess common bean's vegetative and productive responses to varying base fertilization levels.
• To determine the influence of residual bean fertilization on subsequent chia crop growth and yield.

Main Methods:

• A two-stage randomized block design experiment evaluated common bean growth and yield parameters.
• The second stage assessed chia crop development, nutrient uptake, and yield under residual fertilization from the first stage.
• Soil chemical attributes were analyzed post-harvest for both crops.

Main Results:

• Common bean's vegetative and productive parameters showed no significant response to increased fertilization levels.
• Residual fertilization from beans significantly elevated soil phosphorus (P) and potassium (K) levels.
• Chia crop exhibited significant responses in yield, oil content, and leaf P content due to residual fertilization.

Conclusions:

• Increased fertilization does not significantly impact common bean yield under the tested conditions.
• Residual fertilization from common beans positively influences soil P and K, benefiting subsequent chia cultivation.
• Residual fertilization is a viable strategy to enhance chia crop performance, particularly its yield and oil content.
