Abstract

  Dates have been an important basic food for several cultures all over the world and they are still consumed widely over thousands of year. The aim of our study was to protect khadrwai dates from monsoon season and minimize post-harvest losses. For this purpose, some bunches were wrapped with polythene plastic sheet, some covered in sacks and others remained open on date palm. Date samples were collected during Khalal, Rutab and Tamar stage by weekly intervals. Chemical and physical characteristics were determined using published procedures. Result showed firmness was more in polythene plastic dates about 4.733, 4.46 and 1.6 during every stage and other conditions have less firmness. Brix % gradually increases during all stages. At full ripening stage, brix % was near about 30 - 40%. Color changes during ripening from light yellow at Khalal to golden brown at Rutab stage and then converted to dark brown color at Tamar stage. Moisture content was decrease with the passage of time. At Tamar stage, moisture content was about 15 % which was beneficial for long term storage. The highest losses on date palm were observed in sack dates due to shrinkage of size and bitter taste. Monsoon season less effected on opened date palm. Polythene plastic condition is best for maximum production and minimum losses on date palm.
