INFLUENCE OF SUPPLEMENTARY NITROGEN, IRRIGATION AND HORMONES ON FLOWER DROPPINGS, GROWTH AND YIELD OF CHICKPEA

Abstract

The experiment was conducted during the PeI'iO(I from 11 U)ecember. 20121 to 30 March 2013 to study the influence of supplcmentarv nitrogen. irrigation afl(I hormones on flower droppings. growth and yield of chickpea. The experiment consists ol two factors: lactor A: Chickpea variety (2) as V1 : 13AR1 chola 8 and V: BARI chola 9. lactor B: Supplementary treatments (5 levels) as 1 : Control i.e. no spray at flowering and atlerwards: T: Supplemental irrigation before flowering (SI BF); T: SIBF + Aqueous N helore flowering: T.1 : PRI I (a phytohorniolie) spray be fore flowering and Tc: Kinetine spray be tore flowering. The two foctors experiment was laid out in split-plot design with three replications. Statistically significant variation was recorded for di ftereni parameters. The lower flower dropping (60.27%). the lower 1)0(1 dropping (3.62%). maximum pods plani' (27.58). longer pod (1 .85 ciii). maximum seeds pod (1.65). higher shelling percentage (0.69). higher seed yield (1.69 t ha and higher stover yield (2.72 1 ha I) were recorded liom V7 whereas, the higher flower dropping (64.98%), higher pod dropping (3.79%). minimum po(lS plwit 1 (26.03). shorter pod (1.75 ciii). minimum seeds pod -1 (1 .54). lower shelling percentage (0.67), lower seed yield (1 .43 t lia ) and lowei' stover yield (2.47 t ha' ) were recorded from V 1 . The lowest flower dropping (59.17%). the lowest (3. 10%). the maximum pods plani' (28.52). the longest pods (1.95 cm). the maximum seeds pod' (1 .67). the highest shelling percentage (0.73). the highest seed yield (1 .84 t ha') and the highest stover yield (2.84 t ha') were found from T3 . while the highest flower dropping (67.07%). highest pod dropping (4.82%). the minimum pods plant' (25.00). the shortest pod (1 .63 cni). the minimum seeds pod' (1.51). the lowest shelling percentage (0.64), the lowest seed vield (1 .25 ha') and the lowest stover yield (2.33 t ha') were observed from 1,. the lowest flower dropping (57.27 1 /0). the lowest pod dropping (3.07%). the maximum pods plint (28.80). the longest p0(1 (1.96 cm), the maximum seeds pod-1 (1 .74). the highest shelling percentage (0.75). the highest seed yield (1 .94 t ha ) and the highest stover yield (2.92 1 ha') were recorded from V2T and the highest flower dropping (71.20%), the highest 1)0(1 dropping (4.97%). the minimum pods plani' (24.57). the shortest pod (1.45 cm). the minimum seeds pod -1 (1.47). the lo\vest shelling percentage (0.58). the lowest seed yield (1. 19 t hia) and the lowest stover yield (2.11 1. ha') were recorded from V,T, . BARI chola 9 cultivation with applying supplemental irrigation before flowering ± aqueous N before flowering revealed maximum yield contributing characters and yield.
