TITLE: “RAISED BED PLANTING & WIDER SPACING, AN UPCOMING INNOVATIVE RESOURCE CONSERVATION TECHNOLOGY FOR A.COTTON (Gossypium hirsutum L)
CHEEMA GS(2004)RESEARCH CONDUCTED AT DEPTT.OF AGRONOMY& AGROMET.,P.A.U.,LUDHIANA,PUNJAB,INDIA
INTRODUCTION: The current experimental research was conducted at research farms of Department of Agronomy & Agro meteorology, PUNJAB AGRI.UNIVERSITY, LUDHIANA during kharif 2004.The experiment was planned with given objectives:
1. To study the effect of different planting methods on growth & yield of A. cotton
2. To study the effect of different plant to plant spacing on growth & yield of A. cotton.
3. To study the interaction effect (if any) of different planting methods & plant to plant spacing on growth & yield of A. cotton
METHODS: The experiment was conducted in SPLIT PLOT DESIGN with 4 replications.5 planting methods given below were kept in MAIN PLOTS.:
1.Sowing on raised beds at optimum moisture.(BOM)
2.Sowing on raised beds followed by irrigation (BFI)
3.Sowing on raised beds made dry & then irrigated for settlement.(BIS)
4.Furrow planting (Fu P)
5.Flat planting (FP)
Whereas, 3 plant to plant spacing (45, 60 & 75 cm)
Were kept in sub plots.
RESULTS
1) Different planting methods did not significantly influence the Plant Height, Leaf Area Index (LAI), Total Dry Matter Accumulation (TDMA), Sympodial Branches, Bolls Per Plant, Boll Weight & Total Seed Cotton Yield.
2) Plant spacings has non-significant effect on plant height at 30DAS however, it significantly effected the plant height at 60, 90,120,150 DAS as closer spacing (45 cm) recorded highest plant height.(182.4 cm).Similarly, closer spacing recorded significantly higher Leaf Area Index(LAI) than wider spacing.
TDMA was more in wider spacing of 75cm (195g/plant) which was 14.4% greater than of closer spacing (45 cm) at 150 DAS. Similarly, yield contributing characters like sympodial branches, bolls/plant etc. were significantly higher in wider plant to plant spacing of 75 cm than closer spacing of 45&60 cm.
Plant spacing has non-significant effect on seed index and boll weight.
Total Seed Cotton Yield was non significantly effected by plant spacings.
CONCLUSIONS:
1. Different planting methods had a non – significant effect on Total Seed Cotton Yield of A. Cotton .Therefore growing of A. Cotton on raised beds for resource conservation can be adopted.
2. A. Cotton can be grown at wider plant to plant spacing of 75 cm without any significant reduction in Total Seed Cotton Yield. Wider spacing will facilitate cultural & plant protection operations besides reducing the costly seed requirements.
