The present research entitled “Growth and yield of American
cotton (
G.hirsutum L.) as affected by
planting methods and
spacings” was conducted at the Students’ Research Farm, Department of Agronomy And Agro meteorology during kharif 2004.The experiment was laid out in split plot design with four replications. The main plot treatments considered of five planting methods viz .sowing on dry beds followed by irrigation ,sowing on beds at optimum moisture, sowing on beds made dry and then irrigated for settlement ,furrow planting and flat planting. The sub-plot treatments comprised of three plant to plant spacings i.e. 45,60,75
cm .Different planting methods had a non-significant on seedling emergence, plant height, total dry matter accumulation, leaf area index, number of
monopodial, sympodial
branches, flowers and
bolls per plant, setting percentage, lint index, seed index, ginning out turn and total seed cotton yield. Among plant spacings, narrow plant spacing of 45 cm resulted in taller plants with more leaf index than wider plant spacings 60 and 75 cm. However, the wider plant spacing (70 cm) resulted in significantly higher number of sympodial branches per plant, dry matter accumulation(g/plant),number of flowers and total bolls per plant than narrow plant spacings of 60 and 45 cm. Plant spacings had a non-significant on seedling emergence ,boll weight, lint index, seed index, ginning out turn, monopodial branches per plant and total seed cotton yield.
