ABSTRACT

Performance of five sugarcane varieties viz. Bannu-1, Naurang-98, COL-75, S-86-US-422 and PAS-132 was evaluated at 39 locations on farmer's field in Bannu division for four consecutive years. The study revealed that varieties Bannu-1 and Naurang-98 out yielded other varieties during the entire period of investigation. However, amongst these, Naurang-98 exhibited better sugar recovery. Variety S-86-US-422 possessed higher sugar contents as compared to PAS-132 and COL-75. On the basis of results obtained, sugarcane varieties Bannu-1 and Naurang-98 were recommended for general cultivation in the area.

Introduction

The socio-economic conditions in Bannu division are distinct. Its agro-clirnatic conditions are quite favourable for sugarcane cultivation. The crop is commercialized due to Sugar Mills in this area and constitutes 5.66 percent of total sugarcane production of NWFP. The average yield of sugarcane in this part of the province is lower as compared to other sugarcane growing belts in NWFP and Pakistan (Sundera, 1998; Anonymous, 1999). The area under cultivation of sugarcane in Pakistan is one of the biggest (4th) in the world but the yield per unit area is one of the lowest (Nazir, 1994). Ayaz et al. (1997) observed that sugarcane yields on farmer's field in NWFP or elsewhere in Pakistan are much lower than actual yield obtained at experimental farms, where package of technology is applied. Hussain et al. (1999) stated that lack of production technology is one of the major limiting factors in sugarcane improvement. In Bannu, majority of the growers are illiterate and have less awareness about the high yielding varieties and management practices. Therefore, they intend to adopt conventional methods, outdated technology and low yielding varieties.

Selection of suitable variety plays a pivotal role in enhancing the yield up to its potential. Bahadar et al. (2000) recorded the highest cane yield (94.33 t ha–1) from variety Bannu-1. Qayyum et al. (1999) reported that evaluation of suitable varieties at one location proved no worth under all environments. They further emphasized to select varieties on their relative rankings and determine their stability across environments. Atta et al. (1991) stressed upon the constant replacement of old varieties with new one for better production. Malik (1998) warned about the dangerous results of sugarcane variety Co-1148 due to its low recovery and susceptibility to red rot disease.

It is crystal clear from the discussion that timely replacement of old, low yielding varieties and dissemination of new, high yielding varieties is the only viable and feasible approach to cope with the ever increasing sugar demand of the country and increase the Govt revenue in term of foreign exchange.

Keeping in view the above objectives, series of experiments were carried out at farmer's field to evaluate and disseminate the improved varieties and bridge up the yield gap of farmer's field and experimental farms.

Materials and Methods

Investigations were carried out at the farmer's fields of Bannu division from 1995-96 to 1998-99 including four plant and four ratoon crops to study the Performance of five varieties of sugar cane viz Bannu-1, Naurang-98, COL-75, PAS-132 and S-86-US-422 at 39 locations (24 in plant crop and 15 in ratoon stage). Sowing was done in RCB design, replicated four times with a plot size of 10 x 4.5 m. All the recommended cultural and management operations were adopted accordingly in all trials. A basal dose of NP was applied at 150-58 kg ha–1. Phosphorous was applied at 1st hoeing in the month of March. Nitrogen was applied in two equal splits in April and May to plant and ratoon crops. Insecticide "Furadon" g was applied at 20 kg ha–1 to all experimental plots for the control of borers. Weedicide "Gesapex Combi" was applied at 3.5-4.0 kg ha–1 for weeds control. Hoeing and earthling up were also performed. The relevant data were recorded and analyzed statistically with the help of computer package MSTATC.

Results and Discussion

Cane yield: Analysis of mean values indicated that amongst 24 locations, varieties COL-75, Naurang-98 and Bannu-1 produced the highest and on par cane yield of 102.84, 102.00 and 100.53 t ha–1 in plant stage at village "Surani" and "Bakhmal Killa", respectively, during 1995-96 and 1998-99 (Table 1-8). Similarly in ratoon stage, maximum cane yield (107.16 and 104.0 t ha–1) was obtained from Bannu-1 and Naurang-98 at village "Mirian" during 1998-99. Anonymous (1996) reported sugarcane variety Jn-88/2 with average cane yield of 71.66 t ha–1 in Peshawar valley. While Anonymous (1997) advocated maximum cane yield (99.08 t ha–1) of variety Bannu-1 at farmer's field in Bannu area. Glaz (1998) identified CP 80-1827 as a superior variety of sugarcane in Florida. Khan et al. (1998) reported that variety S-82-US-710 produced cane yield of 69-95 t ha–1 on farmer's field. Varieties S-86-US-244, S-86-US-226 produced the highest cane yield (116.8 and 105.71 t ha–1) under different ecological zones of Peshawar valley (Anonymous, 1999).

It responded the highest recovery of 11.76, 11.59 and 11.24. In ratoon stage, higher recovery (10.60 and 10.22%) was noted in Naurang-98 at village "Mirian" and "Niamat abad", followed by Bannu-1 with recovery of 10.0% at village "Niamat abad" during 1998-99 (Table 9-16).

Varieties PAS-132 and COL-75 resulted poor recovery at all locations (Table 9-16). Malik (1998) indicated the dangerous results of variety Co-1 1 48 in Punjab due to its low recovery and susceptibility to diseases. Khan et al. (1998) recorded higher recovery (10.07%) in variety S-82-US-710 on farmer's field in Bannu. Anonymous (1986) reported that sugarcane variety "M-93" possessed the highest recovery of 13.15% at 3 ecological zones of Peshawar valley.
