Abstract/ Executive Summary:

In Bangladesh, Foxtail millet is grown mostly in marginal lands with little care and inputs as a result its average yield is very low (not more than 0.8t/ha). The objective of this study was to generate information on nitrogen requirement of newly developed variety of Foxtail millet. The experiment was conducted during early kharif, 1988 at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. The soil was silty clay with pH 5.6 to 6.2. Nutrient status of the experimental plot was moderate with nitrogen deficient. From this study it is revealed that , 75 kg nitrogen per hectare was found to be optimum for yield maximization of Foxtail millet cv. Bogra-1

Keywords: Nitrogen, Yield, Foxtail millet

End Date: 00-00-1988

Program Area: Crop-Soil-Water Management

Commodity: Foxtail millet

Objectives:

An attempt was undertaken in the present study to generate information on nitrogen requirement of newly developed variety of Foxtail millet.

Methodology:

The experiment was conducted during early kharif, 1988 at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. The soil was silty clay with pH 5.6 to 6.2. Nutrient status of the experimental plot was moderate with nitrogen deficient. The experiment was laidout in a randomized block design with four replications. Bogra-1 was used as test' variety. The seeds were sown on 9th February, 1988 at the rate of 8 kg/ha in 25 cm apart rows. Four levels of nitrogen viz. 45, 60, 75 and 90 kg/ha were the treatments of the study. Half of the dose of nitrogen was used as basal and the rest half as applied in two equal splits during crown root initiation and maximum tillering stages i.e., at 18 and 29 days after sowing, respectively. Phosphorus and potash both at the rates of 45 kg/ha and similarly, zinc and sulphur at the rates of 5 and 20 kg/ha, respectively were applied during final land preparation. One weeding was done at initiation of tillering and one Irrigation was applied at maximum tillering stage. The crop was harvested at full maturity (83 days after sowing). Data on grain yield (t/ha) and yield attributes viz.. number of effective tillers/plant, number of panicles/m , panicle length (cm). panicle weight (g), plant height (cm) and straw yield (t/ha) were recorded and analyzed statistically.

Achievement/Findings:

It is revealed that grain yield of kaon differed significantly due to different nitrogen treatments. Grain yield increased progressively with the increasing rates of nitrogen and highest grain yield of Foxtail millet (3.33 tlha) was obtained with 90 kg N/ha which was statistically identical with that of 75 kg N/ha (3.10 t/ha). Thus, 75 kg nitrogen per hectare was found to be optimum for yield maximization of Foxtail millet cv. Bogra-1
