Abstract/ Executive Summary:

An Experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to examine the effect of planting method and time of N application on productivity of wheat cv. Kanchan. Three planting method viz. broadcasting, line sowing and bed planting method and four time of N application viz., 100% basal application, 1/2basal +1/2 Crown Root initiation (CRl), 1/3 basal +1/3 CRI + 1/3 Panicle initiation (Pl) and 1/4 basal + 1/4 CRl + 1/4 Pl +1/4 at 15 Day After Anthesis were arranged in a split plot design accommodating the planting method in the main plots and the time of N application in the sub-plots with three replications. Result revealed that N application significantly influenced the plant height, number of tillers hill^-1, weight of 1000-grains, straw yield and biological yield. These characters were also significantly influenced by the plating method except 1000-grain weight. The N applied as 1/3 basal + 1/3 CRI + 1/3 Pl produced apparently the highest grain yield (3.22 I ha^-1 and 100% basal application produced the lowest grain yield (2.61 t ha^-1). Highest grain yield (3.17 t ha^-1) was produced by bed planting method. From the present study it may, therefore, be concluded that for obtaining higher yield of wheat cv. Kanchan bed planting method appears as the best method. Since method of N application was found insignificant in respect of grain yield, therefore, the whole amount of N may be applied as basal, which will be most economic.

To examine the effect of planting method and time of N application on productivity of wheat cv. Kanchan.

Methodology:

An Experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to examine the effect of planting method and time of N application on productivity of wheat cv. Kanchan. Three planting method viz. broadcasting, line sowing and bed planting method and four time of N application viz., 100% basal application, 1/2basal +1/2 Crown Root initiation (CRl), 1/3 basal +1/3 CRI + 1/3 Panicle initiation (Pl) and 1/4 basal + 1/4 CRl + 1/4 Pl +1/4 at 15 Day After Anthesis were arranged in a split plot design accommodating the planting method in the main plots and the time of N application in the sub-plots with three replications. The dose of cowdung was 7 t ha^-1. Urea, triple super phosphate, muriate of potash and gypsum were applied at 180, 140, 40 and 110 kg ha^-1 as a source of N, P, K and S. The whole amount of all fertilizers and manure and two-third urea was applied during land preparation and the rest amount of urea was applied during first irrigation. The first, second and third irrigation was given 20, 60 and 80 days after sowing. Weeding and other intercultural operation was done when necessary. Data collection and analysis:The number of leaf, tiller, and grain was counted. Length of different parts of leaf was measured. Dry weights of different parts of the plants were taken by drying them in electric oven (Perkin-Elmer Corporation, USA) at 60°C for 72 hours followed by weighing by digital balance (Kaifeng Group Co., Ltd., China). The grain yield was adjusted at 12% moisture level. The data was analyzed using MSTAT-C program. The mean differences among the treatments were compared by multiple comparison tests using least significant difference (LSD) test.
