Abstract

Cotton is one of the most vital fiber and cash crop of India. The production and productivity of cotton remained low until recent years. Further improvements in cotton yields are possible only through changes in agronomic management and cropping systems. Keeping these in view, current investigations were made to find out the influence of plant spacing and branching pattern on crop growth, flowering, boll production, seed filling, seed yield and quality characteristics of cotton cv. MCU 12. Three different plant spacing viz., narrow spacing (45 × 15 cm), medium spacing (60 × 30 cm) and wider spacing (90 × 45 cm) and three different branching patterns viz., Branching pattern I (3 monopodia and 11 sympodia), Branching pattern II (2 monopodia and 12 sympodia) and Branching pattern III (1 monopodia and 15 sympodia) were studied in this research. Study on the influence of plant spacing on crop growth and seed yield of cotton revealed that a closer spacing of 45 × 15 cm produced more n

Conclusion

Cotton sown at wider spacing of 90 × 45 cm recorded more number of flowers, bolls, higher percentage of filled seeds, more kapas and seed yield plant-1 over medium (60 × 30 cm) and closer spacing (45 × 15 cm). On the contrary, closer spacing of 45 × 15 cm (high density planting) has helped to maintaining more number of plants per unit area that enable to increase the kapas and seed seed yield per ha over wider spacing in the experiment. Within the branches of the different branching pattern, the first formed branches are most efficient in terms of source - sink efficiency as they recorded the highest values for number of bolls branch-1, number of seeds kapas-1, kapas yield branch-1, seed yield branch-1 and 100 seed weight than the later formed branches. As the hierarchy of branching order increased, significant reduction in seed quality parameters were noted.
