Abstract
Fertilizing in a balanced way promotes crop quality and soil health as well as crop growth and production. This study was conducted to determine the best approach of fertilization for jute production in Bangladesh in the experimental fields under Bangladesh Jute Research Institute. A randomized block design with three replications was used to set up the experiment, which included ten fertilizer treatments. The treatments were: T1 – control (no fertilization), T2- 50:10:30:20 kg N:P:K:S ha-1, T3- 100:10:30:20 kg N:P:K:S ha-1, T4- 150:10:30:20 kg N:P:K:S ha-1, T5- 100:5:30:20 kg N:P:K:S ha-1, T6- 100:15:30:20 kg N:P:K:S ha-1, T7- 100:10:60:20 kg N:P:K:S ha-1, T8- 100:10:90:20 kg N:P:K:S ha-1, T9- 100:10:60:10 kg N:P:K:S ha-1, T10- 100:10:90:30 kg N:P:K:S ha-1. The purpose of this study was to determine what nutrition BJRI Tossa pat-8 need for optimal growth and yield. The results indicated significant effect on yield and yield contributing characters over control with different NPK and S levels of BJRI Tossa Pat-8. The highest fibre and stick yield were obtained by the combination dose of N100 Kg ha-1 with 10:60:20 kg P:K:S ha-1. The plant height, base diameter also found highest with the same treatment of fertilizer combination. Therefore this combination (T7- 100:10:60:20 kg N: P: K: S ha-1) seemed to be optimum for good growth and high potential for BJRI Tossa Pat-8 for fibre production in Bangladesh.
Highlights
Jute, an important and the largest natural fiber crop belonging to the genus Corchorus, family Tiliaceae, is an eco-friendly and the major cash crop of Bangladesh
Jute is highly responsive to chemical fertilizer and organic manures
Over-fertilization decreases the efficiency of nutrient use and causes a series of economic and environmental problems [3]
Summary
An important and the largest natural fiber crop belonging to the genus Corchorus, family Tiliaceae, is an eco-friendly and the major cash crop of Bangladesh. The major jute growing areas in Bangladesh are Faridpur, Jessore, Manikganj, Kishoregan, Mymensingh and Rangpur regions It is one of the most popular fibre crops in every districts of Bangladesh. The application of essential plant nutrients in optimum quantity and right proportion, through correct method and time of application is the key to increased and sustained crop production [1]. This over-fertilization by farmers, driven by the desire for higher yields, does not always contribute to high yield but it has recently become a common practice for farmers in China [2].
