In India, which is second largest sugarcane producer in the world after Brazil, this productivity lingers around 28 % of the theoretical maximum. The prevalence of short duration crop cultivation practices likespring and late planting of sugarcane further aggravate the situation. Besides, numerous physiological constraints contributing to low productivity, short duration crop practices mainly succumb to two serious constraints in form short crop growth period and prevalence of high and desiccating temperatures coinciding with the crucial germination and tillering phases. This reduces the crop yields to 30-40 tha-1 and further broadens the gap between theoretical yield and actual yield. Filling the wide yield gaps in sugarcane cropping system is thus a critical target for which realistic measures are required.

Within this contribution, we will introduce the so called Smart Grid Architecture Model (SGAM) which has been developed in the European Commissions’ M/490 mandate. After having proved successful in dozens of projects and especially standardization, the SGAM can be considered as state of the art to document smart grid architectures on a high level. However, as electric mobility is a part of the ...
متن کاملEstimating Sugarcane Yield Potential Using an In-Season Determination of Normalized Difference Vegetative Index
Estimating crop yield using remote sensing techniques has proven to be successful. However, sugarcane possesses unique characteristics; such as, a multi-year cropping cycle and plant height-limiting for midseason fertilizer application timing. Our study objective was to determine if sugarcane yield potential could be estimated using an in-season estimation of normalized difference vegetative in...
