Title of the technology: Improved four crop pattern: Potato–Pat shak–Jute–T. Aman

Year of innovation: 2020

2.

Indroduction: The potato-fallow-Jute-T. Aman cropping pattern is cultivated on about 0.028 million hectares of land in Bangladesh. This technology was developed by JFSD through research activities at farmers’ field during 2017 to 2019.

3.

Salient features of the technology:

a) In the northern region, farmers usually cultivated jute after harvesting of potato, and pat shak (jute leafy vegetables) can be easily introduced between these two crops

b) Potato–Pat shak–Jute–T. Aman cropping pattern could yield 25-30% higher gross return than the practice of existing farmers’ pattern

c) This technology was developed by JFSD through research activities at farmers’ field during 2017 to 2019

Method of Fertilizer Application

Two-third of urea and all other fertilizers should be applied at the time of land preparation and remaining urea fertilizer in 35-40 days after sowing during earthing up on rows.

One-third of urea and all other fertilizers should be applied at the time of land preparation and remaining urea fertilizer in 20-25 days after sowing.

One-third of urea and all other fertilizers should be applied at the time of land preparation and remaining urea fertilizer in equal 2 installments 20-25 and 40-45 days after sowing.

Complete TSP, MP, Gypsum and Zinc fertilizer should be applied at the time of land preparation and urea fertilizer in 3 equal installments 10, 30, 45 days after transplantin.
