Change in growth and yield characteristics of Musa cv Mysore ("Embul" banana) with increasing age of the crop

Abstract

Banana (Musa spp.) is a major semi-perennial fruit crop in Sri Lanka. A study was conducted at the Ftegional Agricultural Research and Development Centre, Angunakolapelessa to investigate the effect of age on growth and yield of banana cv Mysore ("Embul", AAB group). Thirty-seven "Embul" banana accessions collected from various ecological regions of Sri Lanka were studied in a Randomized Complete Block Design with three replicates. The observations were recorded in three consecutive years. Number of leaves per clump, LA1 (leaf area index) and penetration of photosynthetically active radiation (PAR) to the crop were recorded a t 4,9,20 and 32 months after planting. Pseudostem height and girth of the crop were investigated a t different ages. Number of combs and fruits per comb, fruit maturity period, bunch weight, total fruit weight, average fruit weight and peduncle weight were also measured. Comb weight, fruit circumference, fruit length and diameter were recorded in the second and last combs. Leaf number and W increased, while penetration of PAR decreased with the age. Except weight of second comb, fruit length in second comb and fruit diameter in last comb, all other characteristics varied significantly with age of the crop. Fruit maturity period increased with the age of the crop to second year and then decreased, while total fruit weight decreased up to second year and then increased. Number of fruits per comb and bunch weight significantly increased after the second year. Stem height and girth, number of fruits per bunch, weight of the peduncle and length of the male axis consistently increased with the age of the crop investigated up to the third year.

Climate warming causes declines in crop yields and lowers school attendance rates in Central Africa

“…Aside from climatic variables, other factors may have affected plantain productivity, such as plot age. Field experiments with bananas have reported both positive (Sirisena and Senanayake, 1997) and negative (Smale and Tushemereirwe, 2007) effects of age on yield. In light of this, it is possible that the decline in plantain productivity observed in Cameroon was due to crop senescence.…”

Study on dyeing behavior of banana fiber with reactive dyes

“…1 Bast fiber was one of the common textile materials in the market used by mankind for thousands of years. 2 Sirisena and Senanayake 3 reported that banana (Musa acuminate) is the most widely cultivated fruit crop in Sri Lanka. There are about 27-28 cultivars grown in the country.…”
