Summary, etc.	Two field experiments were conducted at Sugarcane Research Station, <br/>Thiruvalla in Pathanamthitta district of Kerala state to standardise the surface <br/>methods of irrigation with and without trash mulching and to study the potential of <br/>integrated nutrient management in sugarcane for sustainable cane production. The <br/>study was carried out for a period of two years in plant crops during 1998-1999 and <br/>1999-2000. The influence on growth, yield attributes, yield, quality, nutrient uptake <br/>and physico-chemical properties and biological properties of the soil were <br/>investigated. <br/>. In Experiment No. I viz., 'Standardisation of irrigation management in <br/>sugarcane' the methods of irrigation with and without trash mulching was <br/>investigated. The treatment comprised of 4 methods of irrigation viz., all furrow, <br/>alternate furrow, skip furrow and irrigation once in a month (farmer's practice) <br/>under mulched and unmulched situations. <br/>The results revealed that all furrow irrigation in combination with trash <br/>mulching had positively influenced all the growth-characters, yield attributes, nutrient <br/>uptake and appreciably increased the cane, sugar and jaggery yield. It was <br/>comparable with alternate furrow irrigation with trash mulching. While cane growth <br/>and sugar production was reduced in skip furrow irrigation with or without trash <br/>mulching. Trash mulching also improved physical conditions, fertility status, <br/>microbial population and enzymatic reactions in the soil. It had also shown better <br/>retention and conservation of soil moisture and reduced the soil temperature as <br/>compared to unmulched treatments. Since the combination of trash mulching with <br/>all furrow and alternate furrow irrigation had recorded comparable values for cane <br/> <br/><br/>I <br/>~ <br/> <br/>yield, B : C ratio; it could be possible to economise the use of irrigation water by <br/>. following alternate furrow irrigation with trash mulching during the formative phase <br/>of sugarcane. It was revealed that a water economy to the tune of 41 per cent was <br/>possible in alternate furrow irrigation with trash mulching as compared to all furrow <br/>with trash mulching. By mulching alone an increase of 10 per cent in cane yield <br/>was observed in alternate furrow irrigation. While in all furrow, skip furrow or <br/>irrigation once in a month the beneficial effect of mulching was not visible to such <br/>an extent as in the case of alternate furrow irrigation. Alternate furrow irrigation <br/>under trash mulching had recorded the highest WUE, energy use efficiency and <br/>energy productivity which again suggest the effective and efficient utilisation of <br/>resources with better conservation. <br/>In Experiment No. II viz., 'Integrated nutrient management in sugarcane', <br/>studies with the integrated use of organic sources like press mud, _ trash, green <br/>manuring with cowpea, Acetobacter and Azospirillum inoculation with mineral <br/>nutrition at 50, 75 and 100 per cent dose of NPK and mineral nutrition alone were <br/>carried out. The results revealed that integrated use of press mud at 5 t ha:' with <br/>mineral nutrition at 100 per cent of the recommended dose of NPK had explicitly <br/>increased the growth characters, yield attributes and uptake of nutrients producing <br/>the highest cane, sugar and jaggery yield. However, it was comparable with the <br/>conjunctive use of press mud at 5 t ha" with 75 per cent of the recommended dose <br/>of NPK. Soil inoculation of Azospirillum at 10 kg ha-! with mineral nutrition at <br/>100 per cent or 75 per cent had also produced significant impact on growth, yield <br/>attributes, yield and quality of cane. It also increased the B:C ratio as compared to <br/>the integrated use of mineral nutrition with green manuring, Acetobacter inoculation <br/>or trash application. Application of NPK at 50 per cent of the recommended dose <br/>along with Azospirillum inoculation had shown higher B:C ratio as compared to the <br/>integration of other organics with 50 per cent of the recommended dose of NPK. <br/> <br/>Mineral nutrition without organics even at full dose had produced lesser cane sugar <br/>and jaggery yield as compared to the integrated use of press mud, Azospirillum, <br/>green manuring or Acetobacter along with mineral nutrition at 50 per cent of the <br/>recommended dose of NPK. The conjunctive use of press mud either with 100 or <br/>75 per cent of the recommended dose of NPK had shown comparable values for B:C <br/>ratio, energy use efficiency and energy productivity besides improving physico- <br/>chemical properties and biological properties of soil. Hence, it is possible to save <br/>25 per cent of the recommended dose of NPK by applying press mud at 5 t ha:'. <br/>It can be concluded from the study that alternate furrow irrigation under trash <br/>mulching had resulted in substantial savings in irrigation water during the formative <br/>phase without any reduction in yield or quality. While in integrated nutrient <br/>management, it was concluded that press mud application at 5 t ha' along with <br/>mineral nutrition at 75 per cent of the recommended dose of NPK had increased the <br/>cane yield with a saving of 25 per cent of the recommended dose of NPK. Mineral <br/>nutrition alone even at its full dose recorded comparatively lesser cane yield and <br/>B:C ratio than all other combinations with organics. <br/><br/>
