Abstract

Genotypic yield potential of maize genotypes is greatly affected by planting dates. This study was conducted to determine optimum planting dates of maize genotypes in 2013/14 at Rampur, Chitwan, Nepal. Four genotypes namely RML-4/RML-17, RML-32/RML-17, ACROSS-9944/ACROSS-9942 and S99TLYQ-B were planted at every week from April to March. The experiments were laid out in randomized complete block design with four replications . The result of experiment showed that the highest production (5565 kg/ha) was obtained in August followed by February (5266 kg/ha), June (4475 kg/ha) and July (4255 kg/ha) respectively. The lowest yield (2572 kg/ha) was obtained in the month of November and December planting (3019 kg/ha). The highest grain yield was obtained in RML-4/RML-17 (7392 kg/ha) and RML-32/RML17 (6606 kg/ha), ACROSS- 9944/ACROSS-9942 (5004 kg/ha) during August planting and higher yield of QPM variety S99TLYQ-B was obtained in the month February planting. Winter maize has higher production potential than the rainy season maize. Based on this experiment RML-4/RML-17, RML-32/RML17 and ACROSS- 9944/ACROSS-9942 should be planting in August (winter season) and S99TLYQ-B in February (spring season) for higher grain yield production.

不同种植日期下玉米基因型的产量

玉米的基因型产量潜力受种植日期的影响较大。本研究旨在确定2013/14年度尼泊尔Chitwan Rampur玉米基因型的最佳种植日期。4 ~ 3月每周播种4个基因型，分别为RML-4/RML-17、RML-32/RML-17、cross -9944/ cross -9942和S99TLYQ-B。试验采用随机完全区组设计，设4个重复。试验结果表明，8月产量最高(5565 kg/ha)，其次是2月(5266 kg/ha)、6月(4475 kg/ha)和7月(4255 kg/ha)。11月和12月的产量最低，为2572公斤/公顷，为3019公斤/公顷。8月种植时RML-4/RML-17 (7392 kg/ha)、RML-32/RML17 (6606 kg/ha)、ACROSS- 9944/ACROSS-9942 (5004 kg/ha)产量最高，2月种植时QPM品种S99TLYQ-B产量最高。冬玉米比雨季玉米具有更高的生产潜力。以本试验为基础，建议在8月(冬季)播种RML-4/RML-17、RML-32/RML17和ACROSS- 9944/ACROSS-9942，在2月(春季)播种S99TLYQ-B，以提高籽粒产量。我们的自然(2015)，13(1):45-49
