Effect of P priming on the yield of ricebean intercropped with maize

Transcription

1 Effect of P on the yield of ricebean intercropped with maize Priming Water Improvement in emergence under drought Nutrients Improvement in yield and nutrients content Promising results in wheat and chickpea Water and Zn

2 Ricebean A rainfed crop Water to see the effect on emergence Legume crop P effects

3 Treatments No P application to maize Recommended P application to maize X Sole maize +rice bean (seed not primed) + rice bean (primed with water) + rice bean (primed with 0.1 % P) + rice bean (primed with 1 % P)

4 Treatments details No P application Sole maize No P application to maize + rice bean (seed not primed) No P application to maize + rice bean (primed with water) No P application to maize + rice bean (primed with 0.1 % P) No P application to maize + rice bean (primed with 1 % P) Recommended P application to sole maize Recommended P application to maize + rice bean (seed not primed) Recommended P application to maize + rice bean (primed with water) Recommended P application to maize + rice bean (primed with 0.1 % P) Recommended P application to maize + rice bean (primed with 1 % P)

5 Design = Ranmized block design Replications = 3 Varieties : Maize= Giriza, Ricebean= BRSII

6 Priming Water soaking P with KH 2 PO 4 Sowing Maize + ricebean was sown in 1:1 additive series

7 Observations Maize Plant height Cob length Number of grains per cob Test weight Yield Ricebean Emergence count No. of pods per plant Pod length Test weight Grain yield Nutrient contents Equivalent yield

8 Results Emergence of ricebean No significant effect on total emergence count of ricebean was observed, however resulted in 23 days early emergence of ricebean

9 Effect of seed of ricebean intercropped with maize (mean of two years) Treatments Maize yield (t/ha) Ricebean yield (t/ha) Total maize equivalent yield (t/ha) No P application Sole maize No P application to maize + rice bean (seed not primed) No P application to maize + rice bean (primed with water) No P application to maize + rice bean (primed with 0.1 % P) No P application to maize + rice bean (primed with 1 % P) Recommended maize P application to sole Recommended P application to maize + rice bean (seed not primed) Recommended P application to maize + rice bean (primed with water) Recommended P application to maize + rice bean (primed with 0.1 % P) Recommended P application to maize + rice bean (primed with 1 % P) CD 5% Maize INR 6500/t, Ricebean INR 30000/t

10 Effect of treatment on ricebean yield (t/ha) Ricebean yield (t/ha) N0 Priming Water P 0.1% P 1% Mean P P Mean % increase

11 Effect of treatment on maize yield (t/ha) Maize grain yield (t/ha) With out ricebean N0 Priming Water + ricebean P 0.1% P 1% Mean P P Mean Increase (t/ha) % increase

12 Effect of treatment on maize equivalent yield (t/ha) Maize equivalent yield (t/ha) With ricebean No ricebean N0 Priming Water P 0.1% P 1% Mean P P Mean

16 ? Estimates of heritability, genetic advance & correlation between grain yield and its component in ricebean?some article in LEISA India in relation to farmers participatory activities like mother and baby trials & ricebean demonstration ( ricebean yield, economics, family requirement/sufficiency? etc) Family pulse consumption; production/purchase; ricebean production; saving/income
