Sugarcane is the crop that have the quality to sprout after its first harvesting, phenomenon known as ratooning. Among all other major crops, sugarcane ratooning is widely acceptable to farmers of the Punjab. The more the tillers grew, the higher are the chances of a greater number of stalks to be harvested. It is proven that more the number of stalks, the thinner is the diameter, finally results in more stalks and high production. Similarly, higher number of canes produce favorable ratoon. In this experiment, performance of Seven promising sugarcane varieties/clones along with the check variety CPF-246, were tested for their ratoon ability capacity at farmer’s field at Toba Tek Singh during the year 2017-18. It has been found that one of the varieties S2008-FD-19 produced that maximum ratoon yield, U2003-US-633 produced the maximum sugar recovery and S2003-US-133 produced maximum number of mill able canes. The observing of the current analysis also revealed that S2003-US-633 and S2003-US-133 have significant potential for boom sugar recovery through breeding programs and by improving the production techniques.

Sugarcane is mainly cultivated in the tropical and subtropical regions of the world, and nearly 85% of sugar is used worldwide. The area, production, and yield of sugarcane has been increased worldwide as well as in Pakistan as compared to other crops. It is the second largest economically important crop after cotton. It is a high-value cash crop that has significance for sugar industries in Pakistan. It contributes about 0.6% to the GDP and 2.9% of the total value added in agriculture. It creates huge revenue for the government and is used as a source of energy/power. The climate of Pakistan is favorable for sugarcane production in Punjab and Sindh provinces. Different climatic factors, i.e., sunlight, temperature, germination, tillering, growth, humidity, dew, frost, hailstorm, windstorm, sunburn, and drought, significantly affect the production of sugarcane. Pakistan is a principal cane-growing country and stands at the fifth position in the area, sixth position in cane sugar production, and ninth largest sugar producer in the world. This chapter describes the economic importance, climate, and yield potential of sugarcane in Pakistan.
An experiment was conducted in Sugarcane Research Institute (SRI) Faisalabad during 20172018 and 2018-2019 cropping seasons to find out the effect of different irrigation levels on growth and yield parameters of five sugarcane clones. Sugarcane is a tropical crop with C4 Photosynthetic metabolism. Due to irrigation water shortages, water stress is common in sugarcane. Major Responses of drought in sugarcane is leaf rolling. Stomatal Closure inhibition of stalk and leaf growth, leaf senescence and reduced leaf area (due to its phenomenal dry matter production capacity) are other symptoms of water stress.
Topographical areas better adapted for sugar cane cultivation must be identified and preserved, for this study Indus valley river delta in South Punjab represents promising features for prosperous sugarcane cultivation (lower water pumping costs due to higher water tables, sugarcane being flood resistant crop in Pakistan. Eight sugarcane varieties and eight promising clones were grown on different locations in Punjab at farmer’s field using RCBD with three replications. The objective of this study is to evaluate varieties under different ecological zones. These clones were tested for their proficiency at four different locations during 2018-19. The “Thal” and Southern Punjab viz; 142/TDA Lalazar Layyah, Indus Sugar mills Rajanpur, Ashraf Sugar Mills Bahawalpur and Adam Sugar Mills Chishtian. The data on germination %, tillers / plants, Number of mill able canes, canes yield tones/ ha and commercial cane sugar (CCS) were recorded during the course of study. It is obvious from pooled mean of four locations that cane yield of clone S2002-US-133 gave 84.13 % higher cane yield as compared the check variety CPF 248 as far as CCS% is concerned, sugarcane clones S200-US-633 and S200-US-133 gave the higher sugar recovery that is 15.31 % & 15.23 % respectively more than check variety. Whereas S200-US-658 and HSF240 have the lowest CCS% 1.22 & 1.14 % less than check.
