Abstract

Effect of high quality organic fertilizer with Jack bean for Baby corn Production in Nakhon

Pathom series, was performed in an farmer area at Muang District Kanchanaburi Province since May 2013

until February 2014. The objectives were to compare the effects of a high quality organic fertilizer, high

quality organic fertilizer with green manure and farmers method on baby corn production, chemical

properties of soil and economic returns. The experimental design was randomized complete block with 4

replications and 5 treatments as follows : 1) control without fertilizer application 2) application of

chemical fertilizer at the farmer rate 3) planted 10 kg per rai of jack bean seed 4) applied 1,000 kg per rai

of high quality organic fertilizer and 5) planted 10 kg of jack bean seed integrated with 1,000 kg per rai of

high quality organic fertilizer. It was found that the change of some chemical properties showed decrease

nutrients after the experiment following 1.08 percent of organic matter, 20 mg per kg of available

phosphorus and 183 mg per kg of exchangeable potassium. A maximum yield was found on planted 10 kg

of jack bean seed integrated with 1,000 kg per rai of high quality organic fertilizer was 3,381.36 kg per rai

and the highest of net profit was 9,579.44 bath per rai. The results from these studies conclude that planted

10 kg of jack bean seed integrated with 1,000 kg per rai of high quality organic fertilizer is probably the

best method for baby corn cultivation in Nakhon Pathom soil series.
