I am working on a rice–mustard cropping system and would like to know about the different agronomic traits/parameters that can be recorded or calculated after harvesting.
Some common traits I am aware of include:
- Grain/seed yield
- Harvest index
- Straw/stover yield
Could you please suggest other important agronomic traits (both for rice and mustard) that can be measured post-harvest for better assessment of crop performance and system productivity?
Any references or standard protocols would also be highly appreciated.
After harvesting in a rice–mustard cropping system, several traits can be checked to understand how well the crops grew and how productive the system was. The most common things people measure are the grain yield (how much rice or mustard seed was produced), straw or stover yield (the leftover plant material), and harvest index (the ratio of grain to total plant mass).
Along with these, it is useful to record the weight of 1,000 seeds, moisture content in the harvested grains, plant height, number of pods in mustard or panicles in rice, and the total biomass (all the plant material above ground). For mustard, checking oil content is important because it is mainly grown for oil. For rice, people sometimes also look at the quality of the grains, such as how much starch they contain or how well the grains cook.
Other useful traits are how much leftover crop residue is produced, how easily the plants stand up before harvest (lodging resistance), and how quickly the crops reach maturity. By collecting this information, it becomes easier to compare crop performance, calculate economic returns, and choose the best varieties for future planting in a rice–mustard system
In a rice–mustard cropping system, several agronomic traits can be calculated after harvesting to evaluate crop performance and system productivity. For rice, these include grain yield, straw yield, harvest index, test weight (1000-grain weight), and biomass production, while for mustard, seed yield, stover yield, oil content, and harvest index are commonly measured. System-level parameters such as rice equivalent yield (REY), land use efficiency, production efficiency, and economic returns can also be derived to compare the performance of the cropping system against monocropping. These traits collectively help in assessing not only the yield potential of each crop but also the sustainability and profitability of the rice–mustard rotation.
Can u please provide me the publication links or any other source link to calculate these parameters?? Akash Amulpandi
