Abstract

The present study entitled “Effect of environmental conditions on biometric parameters and yield of broccoli” was carried out at the Experimental farm of the Department of Environmental Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during Rabi 2021-22. In mid hills occurrence of fog is common, thus it is necessity to study the growth of broccoli under different environmental conditions as the yield potential of broccoli is more in the rabi season. The results revealed that treatment (T2M1I1) i.e., Mid-season transplanting (28th Oct) + Mulch + Irrigation recorded significantly higher on biometric parameters i.e., Biometric attributes i.e., Chlorophyll content (2.23 mg/g) and Leaf area index (5.10) showed significant highest values in treatment (T2M1I1) Micrometeorological parameter i.e., Evapotranspiration (2.48mm/day) was found in treatment (T2M1I1). Plant canopy relative humidity and Soil moisture were also recorded. Agroclimatic indices i.e., Crop phenology of 132 days were observed. Growing degree days of 140.10 days/hrs were accumulated in T2. Helio-thermal units of 7248.74 days/hours were observed in T2, Photo-thermal units of 10031.55 days/hrs were observed and, yield (10.44kg) per plot was observed in the treatment of T2M1I1. Treatment T2M1I1 is recommended for improving biometric attributes, micrometeorological parameters, agroclimatic indices, and yield attributes in Broccoli. Among different environmental conditions mulching and irrigation played an important role in the physiological and morphological characteristics of broccoli thus enhancing the crop yield.

Conclusion

The present study revealed that 2nd date of sowing, mulching, and irrigation had a significant effect on the yield of broccoli (208q/ha). The crop transplanted on October 28 took a maximum of days to attain different phenological stages and accumulated the maximum number of growing days and heat units which were reduced with the subsequent delay in transplanting. The mulching and irrigation played an important role in the physiological and morphological characteristics of broccoli thus enhance the crop yield. Hence, treatment T2M1I1 is recommended for improving morphological characteristics, yield attributes and biometric attributes, under different environmental conditions in Broccoli.
