Abstract

The growth and yield characters of chickpea varieties suitable for mechanical harvesting were evaluated through field experiment conducted for three consecutive years (2016__17 to 2018__19) during rabi season on vertisols under rainfed conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh. The investigation was carried out in split plot design with three replications. Two plant geometries (30.0 × 10.0 cm and 22.5 × 10.0 cm) were assigned to main plots and six chickpea varieties (viz., GBM 2, Dheera, CSJ 515, HC 5, Phule G 08108 and BRC 1) were assigned to sub plots. Pooled analysis of experimental results indicated that significantly higher number of branches per plant (8.7) and number of pods per plant (31.1) and test weight (24.3 g) were observed under 30.0 × 10.0 cm when compared to 22.5 × 10.0 cm. Higher plant height (44.8 cm), height of lowest pod bearing branch (30.0 cm), lower days to 50 % flowering (42.1 days) and higher test weight (31.2 g) were observed in Dheera. Higher number of branches per plant (9.2) and number of pods per plant (34.2) were observed in GBM 2. Higher seed yield was observed in Phule G 08108 (1708 kg ha-1) which is followed by GBM 2 (1675 kg ha-1) Dheera (1569 kg ha-1) and BRC 1 (1493 kg ha-1). Higher harvest index (56.4%) was also observed in Phule G 08108. Chickpea varieties GBM2, Dheera and BRC1 were best suitable for mechanical harvesting and higher seed yield due to their excellent morphology.

适合机械采收的鹰嘴豆品种生长及产量特性研究
在安得拉邦南达尔地区农业研究站,通过连续3年(2016__17 ~ 2018__19)旱作条件下的旱作土壤试验,评价了适合机械收获的鹰嘴豆品种的生长和产量特性。调查采用3个重复的分区设计。2个植物几何形状(30.0 × 10.0 cm和22.5 × 10.0 cm)划分为主区,6个鹰嘴豆品种(gbm2、Dheera、CSJ 515、HC 5、Phule G 08108和BRC 1)划分为副区。综合分析结果表明,在30.0 × 10.0 cm下,单株分枝数(8.7)、荚果数(31.1)和试验重(24.3 g)显著高于22.5 × 10.0 cm。其株高(44.8 cm)、最低结荚枝高(30.0 cm)、开花时间低于50% (42.1 d)、试验重(31.2 g)较高。gbm2的单株分枝数(9.2)和荚果数(34.2)较高。Phule G 08108籽粒产量最高(1708 kg ha-1),其次是gbm2 (1675 kg ha-1)、Dheera (1569 kg ha-1)和BRC 1 (1493 kg ha-1)。Phule G 08108收获指数较高(56.4%)。鹰嘴豆品种GBM2、Dheera和BRC1形态优良,最适合机械收获,产量较高。
