Agronomic characters of jute, kenaf and their plant biomaterials effect on soil nutrient

2002

A field study was carried out with three fibre crop varieties to estimate the bulk organic materials produced by each variety and soil nutrient status due to their incorporation into soil. Considerable amount of plant biomaterials were produced by all varieties viz., CVL-1(6.4t ha-1), 0- 9897(7.56t ha-1) and HC-95(9.02t ha-1. Plant biomaterials of each variety enriched the soil nutrient status over the initial value. Highest nutrient status (OC-1.7%, OM-2.95%, N- 0.58%, P-23 ppm, K-0.79 meq/100) was found for variety HC-95. The highest percent increments of these nutrients over the initial nutrient of soil(INS) and not allowed to decompose the plant biomaterial in soil (NBM) [OC over INS (211 %), NBM 1159%); N over INS (190%), NBM (81 %); K over INS (93%), NBM (72%)) were found with variety HC-95. The highest P(28 %) was obtained with 0-9897 where percent increment of P over INS and NBM was 115%. In production of biomaterials and enrichment of soil, Kenaf performed better than Jute varieties. The cultivation of jute and Kenaf may be an exceptional source of organic materials which may save the depleted soil of Bangladesh without using external organic matter.
