SUMMARY
The experiment was carried out during the kharif season of 2006-07 at Central Research Farm,
Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, India which is situated at 230N latitude and 890E longitude and at an elevation of 9.75 m above the mean sea level to study the effect of nitrogen levels on different varieties of teosinte [Euchlaena maxicana (L.) Schrod] in new alluvial zone of West Bengal. The soil of the experimental field was sandy loam alluvial soil. The soil was neutral in reaction pH 6.8, oxydizable organic carbon 0.43 per cent, total nitrogen 0.047 per cent, available phosphorus 46 kg/ha and available potassium 241 kg/ha. The experiment was laid out in factorial randomized block design with 12 treatments and three replications. The treatments were first factor teosinte variety with five levels viz., JHT-04-1, JHT-04-2, JHT-04-3, TL-1 and Improved Sirsa and second factor nitrogen with three levels viz., N30, N60 and N90. The significantly highest green fodder yield of 403.13, 447.92 and 473.07 q/ha was recorded with variety TL-1 treatment, N90 treatment and combined effect of TL-1 × N90 treatment, respectively. The increasing nitrogen levels increased plant height, plant population, dry matter yield and green fodder yield. The increasing trend of crude protein was observed with increasing nitrogen levels. Among the varieties, TL-1 and JHT-04-3 performed well in all aspects in new alluvial zone of West Bengal.
Key words: Teosinte variety, nitrogen, fodder yield, crude protein
