Abstract

Benniseed ( Sesanum indicum L) is a well known oilÐseed crop grown mostly in the Savannah areas of Nigeria, and with little cultivation in the forest south. A two-season experiment was conducted in 1997 and 1998 to determine the effect of plant population and nitrogen application on podrot, oil content and pod weight of benniseed in the rain forest belt of Nigerian. Analysis of variance indicated that only the podrot and oil content were affected by plant population. An increase of 15.6% and 16.2% in oil content was recorded when plant population increase from 111,111, to 250,000 plants/ ha recorded list podrot 2.02; 2.30 in 1st and 2nd seasons while 60kg/ha recorded lowest podrot 2.59; 2.63 in 1997 and 1998, respectively. The 0kg/ha (control) recorded highest podrot 3.14; 3.46 in 1997 and 1998, respectively. An increase of 15.6% and 16.2% oil company was recorded when plant population increased from 111,111 to 250,000 plants/ha in the 1st and 2nd seasons, respectively. Further increase from 62,500 to 111,111 resulted to further increase of 4.6 and 5.2 in the 1st and 2nd seasons, respectively.

果粒、含油量和荚果重的管理

本尼塞德(Sesanum indicum L)是一种众所周知的oilÐseed作物，主要生长在尼日利亚的大草原地区，在南部的森林中很少种植。1997年和1998年在尼日利亚热带雨林地区进行了两季试验，研究了不同种群和施氮量对甘油三酯果粒、含油量和果粒重的影响。方差分析表明，植群对豆粕和含油量有显著影响。当植物种群数从111,111株/ ha增加到25万株/ ha时，其含油量分别增加了15.6%和16.2%;第1、2季为2.30,60公斤/公顷最低，为2.59;1997年和1998年分别为2.63人。0kg/ha(对照)最高产量3.14;一九九七年及一九九八年分别为3.46宗。第1季和第2季植物数量分别从111111株/公顷增加到25万株/公顷，增加了15.6%和16.2%。从62,500人增加到111,111人，导致第一季和第二季分别增加4.6人和5.2人。关键词:管理，豆荚，油含量，豆荚重量，Benniseed, Ultisols发现与创新Vol. 19 (3) 2007: pp. 172-176
