SUGARCANE,a C4 PLANT IS CONSIDERED AS ONE OF THE MOST EFFICIENT CONVERTORS OF SOLAR ENERGY. GERMINATION PHASE; WHEN CULTIVATED COMMERCIAL, SUGARCANE IS PROPAGATED ONLY VEGETATIVELY BY STEM PARTS OR BY WHOLE STEMS. SEED PROPAGATION IS EMPLOYED ONLY IN SELECTION. PLANTING,CUTTINGS SHOULD HAVE ATLEAST THREE BUDS. SPROUTING PHASE~ (THE BEGINNING IS MARKED BY 10% AND THE COMPLETE STAGE BY 75% PF SPROUTS) IS THOUGHT COMMERCE WHEN TWO LEAVES APPEAR ON THE STEM. TILLERING PHASE ~ 1= TILLERING OF SUGARCANE IN THE TROPICS BEGIN SOON (IN ABOUT 15-20 DAYS) AFTER THE FIRST SPROUT APPEAR 2=THE SECONDARY SPROUTS ARE FORMED FROM UNDERGROUND BUDS 3=IN EARLY RIPENING VARIETION OF SUGARCANE,TILLERING LASTS FOR 4-6 MONTHS 4= IN THE LATE RIPENING VARIETIES OF SUGARCANE TILLERING LASTS LONG AS 6-8 MONTHS. 5=EVERY NEW SPROUT APPEARS IN 2-4 DAYS UNDER FIELD CULTIVATION EACH PLANT DEVELOPS; (a) IN THE STRONG - BUSHY VARIETIES 20-40 SPROUTS ( b) IN MEDIUM-BUSHY 15-25 SPROUTS (C) AND IN WEEKLY - BUSHY 8-12 SPROUTS GRAND GROWTH PHASE; * THIS STAGE LASTS FOR 5-8 MONTHS. SUGARCANE PLANTS NORMALLY VEGETATE AT THIS STAGE , IF PROPERLY SUPPLIED WITH HEAT & MOISTURE.
* GRAND GROWTH PHASE STARTS FROM 120 DAYS AFTER PLANTING & LASTS UPTO 270 DAYS IN A 12 MONTH CROP.DURING THE EARLY PERIOD OF THID PHASE TILLER STABILIZATION TAKES PLACE. OUT OF THE TOTAL TILLERS PRODUCED ONLY 40-50% SURVIVES BY 150 DAYS TO FORM MILLABLE CANE * MOST IMPORTANT PHASE OF THE CROP WHEREIN THE ACTUAL CANE FORMATIOM & ELONGATION AND THUS YIELD BUILDUP TAKES PLACE. *LEAF PRODUCTION IS FREQUENT & RAPID *UNDER FAVOURABLE CONDITIONS STALKS GROW RAPIDLY ALMOST 4-5 INTERNODES PER MONTH MATURATION AND RIPENING~ * THIS PHASE LAST FOR ABOUT 3 MONTHS * ITS MATURATION IS DETERMINED BY A DEFINITE SUCROSE LEVEL IN THE STEMS (UPTO 14-16% ) STEM MASS AND A LOW LEVEL OF REDUCING SUGAR. *YHE COMMERCIAL RIPENING OF STEMS CAN BE IDENTIFIED QUITE RELIABLY BY THE RATIO OF REFACTOMETRY INDICES OF JUICES TAKEN FROM THE 7TH - 8TH INTERNODES & LOWER (0.95-0.98). IN TROPICS, BY HARVESTING TIME THE SUGARCANE STEMS ACCUMULATE ON THE AVERAGE UP TO 14-16% SUGAR , IN SUBTROPICS 8-12% SUGAR.
