International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Results
Initial observations on culm height, collar diameter and number culms per species were
recorded after planting. The survival of bamboo species was 100% at the end of one year.
Performance of three bamboo species were observed for culm height, 5 th internode diameter
and total no of culms. Among the three species, Bambusa nutans (99.21 cm) recorded higher
average culm height followed by Bambusa balcooa (70.9 cm) and Bambusa tulda (61.4 cm);
whereas Bambusa balcooa (0.80 cm) recorded higher average collar diameter (0.80 cm) and
total no of culms (82) followed by Bambusa nutans (0.59 cm and 68, respectively) and
Bambusa tulda (0.52 cm and 52, respectively) at end of 06 months after planting.
Conclusion
Preliminary results indicated that, all three bamboo species performed well under rainfed
conditions.

Sweet corn an excellent source of sugars, dietary fiber, vitamin-C, beta-carotene, niacin,
calcium and potassium faces the problem of season-long weed competition which ultimately
reflects into considerable yield loss. Weeds not only compete for light, water, nutrient and
carbon dioxide but interfere with harvesting and increase the cost involved in crop production.
Thus weeds in sweet corn reduce the green cob yield upto 56%. Weed management is a difficult
task for kharif sweet corn due to slushy or hard field conditions that emerges as a result of
aberrations of monsoon and scarcity of labour. Under such circumstances chemical weed
management is more feasible, less laborious, cost effective and economical in sweet corn.
Studies reported that herbicides controlled 65-90% of weed flora and gave 100-150% more
maize yield than weedy check (Nadeem et al. 2006). Taking into consideration the above facts,
