The Effect of Two Different Agro Climatic Conditions on Growth and Yield Performance of Sugarcane Genotypes

Abstract

Sixteen (16) Sugarcane genotypes response were studied in an experiment “genotype x location interactions” in two different agro-ecological zones (Mardan and Harichand) of Khyber Pakhtunkhwa, Peshawar-Pakistan during 2011-12 and 2012-13. The experiment was laid out in triplicate Randomized Complete Block (RCB) , design with plot size of 67 m 2 (10 m × 6.7 m). Combined analysis of variance was used to identify the presence of genotype x location interactions from replicated multi-environment trials. The data revealed significant variations among the genotypes for percentage germination, tillers, plant height, nodes plant -1 , internode length and cane yield at 1% probability level. It was observed that none of the genotypes could show superiority with respect to all attributes. However, the mean performance over locations and years indicated that the check genotype Mardan-93 remained superior by showing maximum buds germination of 42.26%. The maximum number of tillers (259.17), plant height (189.41 cm), nodes plant -1 (22.23), internode length (16.97 cm), cane diameter (23.29 mm), cane yield (68.42 t / ha), millable canes (87.83), sugar recovery (10.57%) and sugar yield (7.07 t / ha) was recorded for genotypes MS91CP238, MS99HO391, Hoth127, MS94CP15, S97CP288, MS99HO317, MS92CP979, MS91CP272, MS99HO93, MS99HO93, MS99HO93 and MS99HO317, respectively against check genotypes. It was concluded that genotypes MS99HO317, MS99HO93, MS92CP979 and MS91CP238 were superior at SCRI, Mardan (test location-I) based on tillering ability, milliable canes, cane yield, sugar recovery and sugar yield. Sugarcane Seed Multiplication Farm (SSMF), Harichand-Charsadda. (test location-II), the cultivars MS91CP272, MS99HO391, MS94CP15 and MS99HO391 were superior based on tillers, milliable canes, sugar recovery and sugar yield compared to other genotypes. The combined over years and locations performance exhibited that the genotypes MS99HO317, MS91CP238, MS92CP979 and CP89831 were superior in terms of percentage germination, tillers, cane yield, number of millable canes, sugar recovery and sugar yield.
