  A investigation was undertaken to assess the interrelationship of cane yield and its traits in sugarcane at National Sugar Crops Research Institute, farm Thatta, during 2000-2001. It was observed that cane girth, number of internodes per plant, cane height and millable canes m-2 were positively and highly significantly correlated with cane yield, the regression coefficients for these traits on cane yield were also positive. Multiple correlation and partial regression analysis indicated that cane girth, number of internodes per plant, cane height and millable canes m-2 should be considered in selecting high yielding strains.

  Performance of seven new sugarcane genotypes developed through fuzz was assessed alongwith two local checks at National Sugar Crops Research Institute, PARC Farm, Thatta during 2000-2001. Analyses of variance revealed highly significant differences among genotypes for cane yield and yield components. Th-10 was superior in girth (27.41 mm), height(277.67 cm), number of internodes per cane (29.84) and weight per cane (1.089 kg). S-84-I-736/88 and LCP-81-10/9 possessed maximum number of millable canes per m2 (13.5 and 12.67) and positively correlated with number of millable canes per m2 (0.818**), weight per cane (0.676**), height (0.622**), number of internodes per cane (0.494**) and girth (0.114). Coefficient of determination and regression coefficient values rated number of millable canes per m2 as a major cane yield component

  Performance of commercial and promising sugarcane varieties viz. Gulabi-95, NIA-98, Triton, Th-9, Th-10, Th-33 and Th-34 along with standard variety BL-4 was studied under agro-climatic conditions of Thatta during 2000-2001. Observations on quantitative parameters i.e. cane girth, number of internodes/ stalk, stalk height, millable canes m-2 and cane yield t ha-1 as well as on qualitative characters i.e. Brix%, Pol%, purity% and sugar recovery % were recorded. The data revealed that promising varieties Th-10, Th-33 and Th-34 showed best performance in respect of cane yield with mean values 113, 112.5 and 109 t ha-1 respectively against standard variety BL-4 (100 t ha-1). While two varieties Th-9 and NIA-98 produced lowest average cane yield 82.5 and 87.2 t ha-1 respectively against the check. Highest average sugar recovery was observed in Th-10 (11.43%) followed by Th-34 (10.70%) and Th-33 (10.16%) against the check variety BL-4 (9.70%). How ever, the commercial varieties NIA-98 and Gulabi-95 gave lowest sugar recovery with average values 8.70 and 8.91% respectively against the check. On the basis of overall performance it was inferred that promising varieties Th-10, Th-33 and Th-34 might prove best commercial sugarcane varieties in future.

  Zinc status was assessed in soil and plants under sugarcane cultivation in taluka Nawabshah during 1997-98. For this purpose fifty sites were sampled at depths of 0 to 15 and 15 to 30 cm, while plant samples recent mature leaves from the third top in sugarcane were collected from the same sites. Soil was analyzed for different physico-chemical properties and available zinc. However, plant samples were tested for zinc content only. The data revealed that most of the soil samples were heavy in texture; only few were light to medium in texture. It was further observed that the soils of the area were calcareous (CaCO3 = 15.43 to 15.40%), non-saline (EC = 0.82 to 0.91 dS m-1), alkaline (pH = 7.80 to 7.78) in reaction and low in organic matter (1.02 to 0.76%). The availability of zinc in soils was low and 98% soils were deficient in this element. The plant analysis, however, showed entire different results. Most of the plant samples (84%) were sufficient and only 16% were deficient in zinc content. The present study thus indicated that sugarcane plant has ability to absorb the required quantity of zinc from the soil within its growing season.
