Duration for VBN 8 Black Gram Variety: Everything You Need to Know
Black gram is an important pulse crop grown in India, especially in the southern region. It is also known as urad or mungo bean. The VBN 8 is a new variety of black gram developed by the Tamil Nadu Agricultural University (TNAU) that is gaining popularity among farmers due to its high yield potential, disease resistance, and tolerance to heat and drought.
The duration of black gram varieties is an essential factor in determining the cropping system and season. The length of the crop cycle varies depending on the environmental conditions, management practices, and genetic traits of the variety. In this article, we will discuss the duration of VBN 8 black gram and its implications for farmers.
VBN 8 Black Gram Variety: Characteristics and Yield Potential
VBN 8 is a determinate variety of black gram with a spreading growth habit. It has a high yield potential of up to 10-12 quintals per hectare under optimal conditions. It is resistant to major diseases such as mungbean yellow mosaic virus (MYMV) and powdery mildew. It also has excellent heat and drought tolerance, making it suitable for cultivation in rainfed areas.
Duration of VBN 8 Black Gram Variety
The duration of VBN 8 black gram variety ranges from 85 to 95 days, depending on the sowing time and location. The crop matures earlier than other varieties such as T9 and ADT 3, which takes around 100-120 days to mature. Therefore, VBN 8 is suitable for cultivation in short-duration cropping systems, especially in areas with limited water availability or for double cropping with other crops.
The crop duration of black gram also affects the yield potential, crop management, and pest and disease incidence. Longer duration varieties have more time to accumulate biomass and fill the pods, resulting in higher yield potential. However, they also have higher pest and disease pressure, especially towards the later stages of the crop cycle. Shorter duration varieties are easier to manage and less susceptible to late-season pest and disease outbreaks. They are also suitable for direct-seeding systems, as they require less labor and input.
Conclusion
The duration of VBN 8 black gram variety is a crucial factor in selecting the right cropping system and management practices. Farmers can take advantage of its early maturity and high yield potential to achieve better returns on investment and reduce risks associated with weather variability. VBN 8 is also an excellent choice for areas with limited water availability, as it can be grown as a standalone crop or in double cropping systems. Therefore, farmers need to consider the duration and other characteristics of black gram varieties when planning their cropping strategy and selecting the right seeds.
