Continued application of the same chemicals as herbicides could develop resistance of weeds to the herbicides. Hence, screening of newly developed herbicide formulations is essential to find out more effective herbicides for controlling weeds in sugarcane at different growth stages of the crop and the weeds. An experiment was conducted to find out...

Global warming cause due by increasing atmospheric CO2 concentration, and the resulting increase in air temperature is a considerable challenge in crop production. Hence, the objectives of this study were to determine the: (a) responses of biomass and sucrose accumulation of sugarcane to elevated CO2 (ECO2) and elevated temperature (ETa), both indi...

Effect of climate4 change on sugarcane

Increased atmospheric CO2 and consequent increases in temperature are two prominent features of climate change, a major challenge to crops. Here, our objectives were to determine: (1) the responses of sugarcane during the first 90 days of elevated CO2 (ECO2) and elevated temperature (ETem), both individually and together, and (2) the genotypic vari...

A study was conducted to identify the causatives for low ratoon yield in sugarcane plantation special reference to hydro-geomorphologic parameters of the landscape. Hydro-geomorphologic parameters i.e. closed depressions, flow accumulation and topographical wetness index were assessed. These hydro-geomorphologic parameters were used as indicators f...

A field experiment was conducted at the research farm of the Sugarcane Research Institute, Uda Walawe,Sri Lanka to find out the feasibility of reducing gross irrigation water requirement of irrigated sugarcane by practising alternate-row furrow irrigation method in Reddish Brown Earth soil (RBE). The effects of the three treatments, i.e., every fur...

Changing rainfall pattern and shifting monsoonal weather are critical climatic factors affecting sugarcane production in Sri Lanka.The scarcity of water to fulfill the irrigation requirement coupled with prolonged drought have severely affected the sugarcane production.A shift of fauna, flora, and microbial population with changing climatic conditi...

Abstract A field experiment was conducted to evaluate sugarcane varieties based on their radiation use efficiencies (RUE) at the Sugarcane Research Institute, Uda Walawe, Sri Lanka. Sugarcane was grown under irrigated (soil water potential[-0.05 MPa) and rain-fed conditions in a split plot design. Biomass accumulation, canopy development, leaf angl...

The objective of this study was to investigate the effects of soil moisture deficits on the growth of root system and its effect on soil moisture utilization in sugarcane to identify relationship of root growth with drought tolerance of sugarcane varieties. An experiment with eight sugarcane varieties under rain-fed and irrigated conditions in a sp...

ABSTRACT The study was conducted to evaluate some physiological characters of commercial sugarcane varieties under different growing conditions in Sri Lanka. A field experiment was conducted at the Sugarcane Research Institute, Uda Walawe (6o21’N latitude, 80o48’E longitude and 76 m altitude) using eight sug-arcane (Saccharum hybrid L.) varieties g...

The objective of this study was to determine the effects of soil moisture deficits on growth, physiology and yield of sugarcane varieties in order to identify drought tolerant varieties and specific traits. The experiment was conducted in 2002/03 at the Sugarcane Research Institute, Sri Lanka (6o21'N, 80o48'E). Eight commercial varieties (SL 7103,...
