“…The returns were higher in the narrow spacing of 60 X 15 cm due to the higher plant population per unit area. These results are in accordance with the report of Meena et al (2017) that maximum net return (R57553 ha -1 ) and B: C ratio (2.50) was at 90 x 45 cm closer spacing over 90 x 60 cm spacing (R45690 ha -1 ) and 90 x 90 cm (R40565 ha -1 ) wider spacing.…”

Plant population is an important attribute in crop management practice. Increasing the plant density by decreasing the crop row spacing was an alternative strategy to optimize crop profit. Hence, the field trial was conducted at Tamil Nadu Agricultural University, Coimbatore, during the winter season of 2017 – 18 to study the effect of row spacing on the growth and yield of cotton genotype TCH 1819. The experimental design was Randomized Block Design (RBD) with seven spacing treatments viz., T1: 60 x 15 cm (1,11,111 plants ha-1), T2: 60 x 20 cm (83,333 plants ha-1), T3: 75 x 15 cm (88,888 plants ha-1), T4: 75 x 20 cm (66,666 plants ha-1), T5: 75 x 30 cm (44,444 plants ha-1), T6: 90 x 15 cm (74074 plants ha-1), T7: 90 x 20cm (55,555 plants ha-1) and was replicated thrice. Plant densities showed a significant (p=0.05) difference for all the characters studied. The higher plant density of 1,11,111 plants (60 x 15 cm) observed significantly (p=0.05) maximum plant height (103.14 cm), Leaf Area Index (LAI) (4.35), Dry Matter Production (DMP) (8125 kg/ha), Crop Growth Rate (CGR) (6.58 g/m2/day), root length (41.46 cm), root dry weight (14.94 g/plant), and chlorophyll index (48.24). The number of sympodial branches per plant (17) and bolls per plant (22 bolls) was found significant in the wider spacing of 75 x 30 cm. The narrow spacing of 60 x 15 cm noted the highest seed cotton yield (2565 kg/ha), net return (R65706.62), and B: C (2.32) ratio, followed by the spacing of 75 x 15 cm due to more plant density per unit area (m2). So, maximum yield in cotton can be achieved by decreasing the row spacing and increasing the plant population per unit area.

“…In cotton, the crop geometry has influence on seed cotton yield. Closer plant geometry recorded higher seed cotton yields Parlawar et al, 2017;Madavi et al, 2017 andMeena et al, 2017. Plant competition for resources in higher population resulted in smaller cotton plant with a higher resource use efficiency (Liu et al, 2020) but results in poor boll load and delayed late-season leaf senescence (Luo et al, 2018).…”

To improve productivity and profitability, it is important to investigate new strategies for cotton production. In April 2020, a field experiment was conducted to study the effect of different plant varieties and spacing on the growth and yield of compact-type cotton. The experiment followed a split-plot design with three replications, with four levels of cotton varieties (Suraj, Supriya, CO 15 and CO 17) in the main plots and seven levels of plant spacing (60 cm x 10 cm, 60 cm x 15 cm, 80 cm x 10 cm, 80 cm x 15 cm, 100 cm x 10 cm, 100 cm x 15 cm, and 75 cm x 30 cm) in the subplots. The results revealed that cotton variety CO 17 had been recorded significantly the highest yield and yield attributes, highest number of sympodial branches per plant and number of squares per plant counted higher when compared to other varieties. However, relative parameters the significantly highest number of bolls per plant counted and higher boll weight was recorded and maximum seed cotton yield harvested with CO 17 variety than others. Results revealed that the 100 x 10 cm plant spacing recorded the highest yield contributing characteristics, such as number of sympodial branches per plant, number of squares per plant and number of bolls per plant. Closer spacing has recorded a significantly higher number of bolls per plant; the highest single boll weight and maximum seed cotton yield were recorded. Among the interaction varieties, CO 17 with a 100 x 10 cm plant spacing registered higher number of sympodial branches per plant, number of squares per plant and number of bolls per plant for yield parameters, comparing to the yield CO 17 with 100 x 10 cm recorded higher seed cotton yield, higher number of bolls per plant and boll weight.
