Survey for fungi associated with leaf spots of sugarcane in Chittoor and Nellore districts of Andhra Pradesh during 1986-87 revealed that 26 species of fungi belonging to 10 genera were found associated with leaf spots of sugarcane. The leaf spots found were minor ones and their incidence was meagre ranging from 1 to 3 per cent in both the districts. In common, the incidence was more in ratoon crop and also in the plant crop aged more than 6 months. The different types of minor leaf spots found on sugar­cane in the 2 districts of Chittoor and Nellore were des­cribed as : Spindle-shaped spots; dark brown linear blotches; reddish brown spindles; reddish brown lesions; Phyllachora leaf stripes; dark brown elongated lesions; dark purple streaks; dark purple midrib streaks; dark red linear lesions and dark red midribs. The morphology and taxonomy of the fungi isolated from the leaf spots were studied and the fungi were identified as belonging to 26 species classifiable into 10 genera

Field performance is described for tissue cultured plants and conventional propagules of planting material of banana cultivar 'New Guinea Cavendish' (Musa sp., AAA group, Cavendish subgroup). Tissuecultured plants were produced by either regeneration of plants from callus culture or by micropropagation of plants following the release of dormant buds at the leaf axils of explants. The conventional material consisted of suckers and 'bits' (lateral buds and associated corm material). Tissue-cultured plants established more quickly, were taller, and had a shorter time to bunch emergence and harvest of plant crop than conventional planting material. They had significantly (P<0.05) higher yields in terms of bunch weight, which was a function of greater numbers of fingers and hands. These advantages did not extend to the ratoon crop. Sucker production on tissue-cultured plants was significantly (P<0.01) higher up to 8 months after planting, equal to conventional material from 8 months to harvest, and then significantly lower. Twenty-two per cent of the plants derived from callus were off-types compared with 3% in the line produced by axillary bud proliferation. No off-types were observed in conventional planting material.

SUMMARYThe results of research on the water relations and irrigation needs of sugar cane are collated and summarized in an attempt to link fundamental studies on crop physiology to irrigation practices. Background information on the centres of production of sugar cane is followed by reviews of (1) crop development, including roots; (2) plant water relations; (3) crop water requirements; (4) water productivity; (5) irrigation systems and (6) irrigation scheduling. The majority of the recent research published in the international literature has been conducted in Australia and southern Africa. Leaf/stem extension is a more sensitive indicator of the onset of water stress than stomatal conductance or photosynthesis. Possible mechanisms by which cultivars differ in their responses to drought have been described. Roots extend in depth at rates of 5–18 mm d−1 reaching maximum depths of > 4 m in ca. 300 d providing there are no physical restrictions. The Penman-Monteith equation and the USWB Class A pan both give good estimates of reference crop evapotranspiration (ETo). The corresponding values for the crop coefficient (Kc) are 0.4 (initial stage), 1.25 (peak season) and 0.75 (drying off phase). On an annual basis, the total water-use (ETc) is in the range 1100–1800 mm, with peak daily rates of 6–15 mm d−1. There is a linear relationship between cane/sucrose yields and actual evapotranspiration (ETc) over the season, with slopes of about 100 (cane) and 13 (sugar) kg (ha mm)−1 (but variable). Water stress during tillering need not result in a loss in yield because of compensatory growth on re-watering. Water can be withheld prior to harvest for periods of time up to the equivalent of twice the depth of available water in the root zone. As alternatives to traditional furrow irrigation, drag-line sprinklers and centre pivots have several advantages, such as allowing the application of small quantities of water at frequent intervals. Drip irrigation should only be contemplated when there are well-organized management systems in place. Methods for scheduling irrigation are summarized and the reasons for their limited uptake considered. In conclusion, the ‘drivers for change’, including the need for improved environmental protection, influencing technology choice if irrigated sugar cane production is to be sustainable are summarized.

The mechanized harvest of sugar cane (Saccharum officinarum L.) in Brazil is an irreversible trend and it comes with a great concern about the quality of the cane delivered to the industry. A key component to quality is the billet length which affects the processing of raw material, cane deterioration, invisible losses and load density of transport vehicles. Thus, due to the importance of the billet standard in quality and cost of raw material, this study aimed to evaluate if the mechanized harvesting of sugar cane can supply the quality requirements for the crushing process, regarding the billet length. A plot with burnt sugar cane (3.2 ha) and another one with green sugar cane (8.0 ha) were selected to be harvested by two (2) self-propelled sugar cane harvesters. For each harvested 0.4 ha a sample from each infield wagon was collected. The sample was composed by ten billets. The variability in burnt sugar cane was higher than in green sugar cane, and both harvesters did not present the capacity of keeping the billets with similar lengths when operating either in burnt or green conditions.

ABSTRACT<br />    <br />Sugar cane is a strategic commodity for the Indonesian government as raw material for the national sugar industry. Cultivation of sugar cane has been shifted to dry areas dominated by Inceptisol, Vertisol, and Ultisol soil. These conditions require certain clones to obtain high sugar yield. New improved varieties have been developed and 8 early-mid maturiting clones have been obtained. The study was aimed to evaluate and obtain earty-mid maturing clones with higher sugar yield than the existing varieties in dry land of Inceptisol soil. The study was conducted at the Karangploso Experimental Station, Malang from July 2015 to September 2016. The study was arranged in a randomized block design with three replications. The treatment consistsed of eight clones of early to mid maturing sugarcane clones and one control variety (Kenthung). The eight clones were (1) PS 04 117, (2) PS 04 259, (3) PS 04 129, (4) PS 05 258, (5) PS 06 391, (6) PS 06 370, (7) PS 06 188, and (8) JR 01. The results showed that three clones (PS 06 188, PS 05 258 and JR 01) produced higher sugar yield (10.45-11.88 ton ha-1), and the other clones showewd lower sugar yield (6.55-9.37 ton ha-1) than that of Kenthung variety (9.16 ton ha-1).PS 06 188 and PS 05 258 clones obtained the highest sugar yield of 11.88 and 11.49 ton ha-1, respectively.<br /><br />Keywords: dry land, performance, Saccharum officinarum,  sugar content, variety<br /><br />

Data are presented here on the effect of synthetic soil conditioners on aggregation and aggregate stability of acid Lares clay and on their effect, with or without lime, on the yields of sweetpotatoes, cotton, and corn. Three conditioners were used: Formulations 6 and 9 of Krilium, and Aerotil, dry form, each at the rates of 900, 1,800, and 3,600 pounds to the acre. There were 20 treatments: Check, lime, conditioners at three levels, and conditioners at the same three levels plus lime. The data presented indicate that these conditioners will stabilize soil structural units, but will not form them. Five crops were grown as a sequence: Sweetpotatoes, cotton, cotton (a ratoon crop), sweetpotatoes, and corn. All crops, except the cotton ratoon, showed some response to the application of soil conditioners. Sweetpotato, a root crop, was more responsive; but the cotton plant crop responded also to stabilized good structural soil conditions. The largest crop responses measured were in the limed treatments. Increases attributable to lime were obtained either in the presence or absence of synthetic soil conditioners. Liming and rational fertilization seems to be the key to increased productivity in some acid soils of Puerto Rico. The synthetic materials do not have practical possibilities in large-scale farming.
