Abstract/ Executive Summary:

Four varieties (BARI hybrid maize-5, BARI hybrid maize-2, BARI maize-7 and BARI maize -5) were tested at the Research field of Crop Physiology and Ecology Department, HSTU, Dinajpur during the period of November 2007 to April 2008 under well watered and non-irrigated water stress condition to evaluate morphological and yield performance of maize in relation to water stress. The experiment was conducted in a split plot design with three replications. The combine effects of growing conditions (water level) and maize varieties significantly influenced plant height, single plant biomass, number of green leaf at dry silk stage, length of leaf blade, length of leaf sheath, number of cobs per plant, cob length, cob diameter, number grains per cob, single cob weight, weight of seeds per cob, 100-seed weight as well as grain yield. Two hybrid varieties (BARI hybrid maize-2 and BARI hybrid maize-5) showed relatively better performance under non-irrigated water stress condition in those morphological and yield characters compared to other varieties (BARI maize-5 and BARI maize-7). Based on drought susceptibility index BARI hybrid- 2 and BARI hybrid maize-5 were found as comparatively drought tolerant than the other varieties (BARI maize-5 and BARI maize-7).

End Date: 00-04-2008

Program Area: Variety and Species

Commodity: Maize

Objectives:

To evaluate the morphological and yield performance of four maize varieties under non-irrigated water stress condition for identifying relatively drought tolerant variety.

Methodology:

The experiment was conducted at the Research field of Crop Physiology and Ecology Department, HSTU, Dinajpur during the period of November 2007 to April 2008 in a split plot design with three replications. The unit plot size was 3m x 2m having a plot to plot and block to block distance of 0.75m and 1.0m, respectively. Two growing conditions- well watered condition (three irrigation levels) and water stress condition (no irrigation) were placed in the main plots as main plot treatments whereas four maize varieties (BARl maize-5, BARl maize-7, BARl Hybrid maize-2 and BARl Hybrid maize- 5) were placed randomly in the sub-plots as sub-plot treatments. The experimental plots were fertilized with N-P₂0₅-K₂0-S @ 138-96-90-27 kg/ha in the form of Urea, TSP, MP and Gypsum, respectively. At the time of final land preparation, cowdung was applied at the rate of 5 t/ha. The whole quantity of TSP, MP, gypsum and 1/3 of urea were given at the time of final land preparation. The remaining urea was top dressed in two equal splits: 1^st at 40 days after sowing (DAS) and 2^nd at 70 DAS. The seeds were sown in lines at 70 x 20 cm spacing. The seeds were placed at depth of approximately 2.5cm from the soil surface. After sowing slight irrigation with overhead sprinkler was given for uniform germination. Number of green leaf at the dry silk stage, length of leaf blade, length of leaf sheath, leaf breadth, plant height, number of fertile cob per plant and single plant weight were recorded from five randomly selected plants from the middle of each plot to avoid border effect. Cob length, cob diameter, number of rows per cob, number of grain per cob, cob weight and grain weight per cob were recorded from five randomly selected cobs. Hundred well dried grains were counted manually for 100 grain weight. Grain yield was measured in t/ha after harvest of whole plot. Grain yield was adjusted to 12% moisture content. The data were analyzed by partitioning the total variance with the help of computer by using MST AT C program. The treatment means were compared using Duncun's Multiple Range Test (DMRT).

Achievement/Findings:

All the varieties showed better performance in the well-watered condition compared to the non-irrigated water stress condition. But the two hybrid varieties showed better performance over the other varieties under non-irrigated water stress condition. Based on the drought susceptibility index BARI hybrid maize-2 and BARI hybrid maize-5 were found as the drought tolerant and BARI maize-5 and BARI maize-7 were considered as drought susceptible.
