Abstract |
The study was conducted at low lying areas in Pabna Sirajgong districts of Bangladesh. To observe the potentiality of bio-mass production two trials were conducted. In first trial maize intercropped with Khesari taking 15 experimental plots of each size 5m 횞 5m were arranged in 5 blocks having homogenous soil characetrstics. the study showed that the bio-mass yield of sole maize and sole Khesari were 35.25 t/ha. and 56.80 t/ha. respectively and there was a significant difference (p<0.05) among them. The results also showed that bio-mass yield of maize and Kherasi was higher (70.04 6.25 t/ha. 98.88 10.77 t/ha. and 80.56 9.5 t/ha) compared to sole maize and sole Khesari and land equivalent ratio was also lower. For second trial, one hectare of land was divided into 16 experimental plots with 4 replications in each plot. Four levels of urea (0 kg/ha, 30 kg.ha, 45 kg/ha, and 60 kg/ha.) were applied to ecperimental plot. The seed rates were 98.8 kg/ha (farmer''''s practice), 86.45 kg/ha, 74.1 kg/ha and 61.75 kg/ha. average bio-mass yeild of matikalai at different seed rates along with urea fertilizer ranged from 38.49 t/ha, to 65.35 t/ha. the highest seed rate along with highest fertilizer also correspond to the peak production (65.35 t/ha) and the lowest seed rate (61.75 kg/ha) along with the lowest fertilizer rate (30 kg/ha.) showed lowest production (38.49 t/ha.). Here, it was found that the bio-mass yield of matikalai increased with the incremental amount of seed, indicating significant effect (p<0.05) of seed rates on the bio-mass yield of matikalai. On the other hand, fertilizer doses in different treatment combinations had significant effect (p<0.05) on bio-mass yield. Two levels of seed rates at zero level of fertilizer were recommended : 86.45 kg/ha for the resource rich farmers and 61.75 jg/ha for the resource poor farmers. |
