Enhanced Efficiency Potassium Fertilizer in Soybean and Cotton Crop

COTTON Relationships between Insufficient Potassium and Crop Maturity in Cotton

difficult to prove cause and effect for maturity differences being responsible for any variation in response Potassium deficiency in cotton (Gossypium hirsutum L.) depresses among genotypes to K. Theoretically, differences in root yield by decreasing late season growth and is reportedly more harmful to early maturing cotton genotypes. Research objectives were to detersystem size or effectivenes...

Variable Rate Application of Potassium Fertilizer for Soybean Crop Growth in a No-till System

Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to evaluate the variable rate application of potassium fertilizer to soybean crop in a no-till system. The study was conducted on a 13-ha soybean grain field in Carambeí, State of Paraná, Brazil in a Ty...

Crop Potassium Nutrition – Implications for Fertilizer Recommendations

Evaluation of Tillage, Nitrogen Fertilizer and Crop Residue Management on some Agronomic Traits of Soybean

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Ability of black soil supplying potassium and effect of potassic fertilizer on soybean

The black land is distributed in a narrow area from south to north in northeast of China Nine soil samples with high, middle and low fertility were collected in the field of south, north and middle area. These samples were analyzed in laboratory, and pot experiment was performed mainly in Harbin. The results showed that Black soil has high potential of providing potassium, the concentration of ...
