Abstract/ Executive Summary:

Potassium is one of the most important essential nutrient elements and it can significantly influence the uptake of other nutrients by plant. Therefore, the field study was conducted to observe the influence of K on the nutritional status of edible leaves of two jute varieties viz. CVL-1 and O-9897 in the experimental field of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh from April to August, 2011. There were five levels of K viz. 0, 10, 20, 30 and 40 kg ha^-1. The land was fertilized as per experimental treatments along with the recommended doses of urea, TSP, gypsum and zinc sulphate to supply N, P, S and Zn, respectively. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Variety as well as different K levels exerted significant effect on protein, chlorophyll and nutrient contents of edible jute leaves. Maximum protein and nutrient contents were found in variety CVL-1 where as the highest chlorophyll content was obtained from the variety O-9897. Protein, chlorophyll and nutrient contents were increased with the increasing levels of K up to 30 kg ha^-1 and then declined. The overall results suggest that K level @ 30 kg ha^-1 can be applied for obtaining nutritious edible jute leaves of the variety CVL-1 under the agro-climatic condition of BAU farm.

Program Area: Quality and Nutrition

Commodity: Jute Leaf

Objectives:

1. An experiment was, therefore, initiated with five levels of K to study the nutritional status of two popular jute varieties viz. CVL-1 and O-9897 and to find out optimum level of K to obtain maximum nutrient content of edible leaves under the study.

Methodology:

An investigation was carried out at the experimental farm of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh during the period from April to August, 2011. Soil sample was collected and kept in a polyethylene bag for chemical analysis. The experiment was consisted of two factors: A. Variety of jute viz. CVL-1 and O-9897 B. Five different doses of K (0, 10, 20, 30, and 40 kg K ha-1). Seeds were collected from the BADC, Mymensingh. There were 10 treatment combinations with variety and fertilizer. The experiment was laid out in RCBD with three replications. The unit plot size was 4 m × 2.5 m. The total number of unit plots was 30. The spaces between replication and between unit plots were 1m and 0.5 m, respectively. The treatments were randomly distributed. At the time of final land preparation, the land was fertilized @ 80, 20, 40 and 7 kg ha 1 of urea, triple superphosphate, gypsum and zinc sulphate, respectively. Muriate of potash was used as sources of K. Seeds were sown on April 30, 2011. After seed sowing weeding, gap filling, thinning, irrigation and pesticide application were performed as and when necessary throughout the growth period of the crop. Plant samples were collected from each of the plot after 35 days of sowing and divided into two parts. One part was kept fresh in the refrigerator until chlorophyll analysis and other part was dried in an oven at 60°C for about 72 hours. Then they were ground to pass through a 20-mesh sieve. The prepared samples were then put into polythene bag. Total N was determined by kjeldahl method. P, K, S, Ca, Mg and Fe and chlorophyll contents were determined by standard methods. Analysis of variance was done with the help of computer package program MSTAT and adjudged the mean differences by LSD Test.

Achievement/Findings:

Variety as well as different K levels exerted significant effect on protein, chlorophyll and nutrient contents of edible jute leaves. Maximum protein and nutrient contents were found in variety CVL-1 where as the highest chlorophyll content was obtained from the variety O-9897. Protein, chlorophyll and nutrient contents were increased with the increasing levels of K up to 30 kg ha^-1 and then declined. The overall results suggest that K level @ 30 kg ha^-1 can be applied for obtaining nutritious edible jute leaves of the variety CVL-1 under the agro-climatic condition of BAU farm.
