Abstract/ Executive Summary:

For cultivation of mustard and rapes. sowing date has been found to be an important factor in influencing the seed yield. A thorough knowledge on the physiological processes of the crop in relation to sowing date effects may be helpful in bringing about its yield improvement. This paper reviews in detail the effect of sowing dates on plant development, growth and yield parameters of mustard and rapes.

Program Area: Crop-Soil-Water Management

Commodity: Mustard

Objectives:

To determine the suitable sowing date of Mustard and Rapes for higher yield

Methodology:

This is a review paper and it discussed detail about different parameters of Mustard and Rapes. Following are the parameters-Developmental Stages, Growing season, Plant Height, Branches/Plant, Leaf Area Index (LAI), Dry Matter Production, Pods/Plant, Seeds/Pod, Thousand Seed Weight, Seed Yield etc.

Achievement/Findings:

From the detailed discussion it appears that climatic condition varies globally from location to location and season to season. Rapes and mustard, as because, are more sensitive to thermal and photoperiodic effects, they are grown in a particular place and time to suit the environment. Hence, there can not be a fixed sowing date for all locations. Therefore, studying the effects of sowing date with respect to crop developmental phases and plant characteristics together with final yield may be of immense importance. Some information on the physiological response of the crop to sowing dates is available elsewhere, however, this sort of information is almost lacking, particularly with the cultivars available in Bangladesh.
