Studies on growth and yield characters of chickpea (Cicer arietinum L.) varieties suitable for mechanical harvesting

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.

Response of Different Pre-Sowing Seed Treatments with Biofertilizers, Biostimulants and Botanicals on Growth, Yield and Yield Attributing Traits in Chickpea (Cicer arietinum L.) var. Desi Himmat

“…and minimum of 32.02% was shown by the untreated control (T0) respectively. These results were in conformity with the earlier research findings of [8].…”

“…took 70.67 days for the same. Similar trends for days to 50% flowering were found by earlier research works of [8].…”

Feasibility study of cultivating desi‐type chickpea genotypes in cold and temperate regions

“…The lowest pod height was also formed at a higher height from the soil surface in tall plants. In chickpeas, the lowest pod height is usually between 15 and 20 cm (Basha et al, 2018). Lack of access to cultivars with the appropriate lowest pod height, especially in developing countries, is considered as one of the most important reasons for a decrease in the cultivated area of chickpea in the world in a way that increasing chickpea production in developed countries such as Australia, Canada, and the United States is mostly contributed to mechanized harvesting (Basha et al, 2018).…”

Chickpea (Cicer Arietinum L.) Genotypes Evaluation for High Yield Through Multivariate Analysis

“…Despite the small seed weight, the plants were taller (73.22 cm) (Table 5). Mechanical harvesting of chickpeas has a severe problem because of the crop height and header loss in combined harvesting (Basha et al, 2020).…”

“…Principal component analysis (PCA) can transform several possibly correlated variables into a smaller number of variables in a group called principal components . Through cluster analysis (CA), the genotypes are grouped based on complex traits rather than one character (Brown-Guedira et al, 2000). Past studies revealed the clustering of 17 chickpea genotypes from different geographical origins, seed colors, and grain yields into eight groups (Dani and Murty, 1985).…”
