Abstract: A trial was performed over three cycles at the Yawal Research Station in Maharashtra State. Aldicarb in pellet form (Temik 10G) was applied in amounts of 1.25 g (1), 2 g (2) and 3g (3) per plant around banana plants 3 months after June planting and 10 months after October planting to control nematodes and aphids. The treatments were compared with a...see more

Abstract: A list of the main weeds found in banana plantations. Description of control methods: manual, mechanical and chemical (by contact or translocation). A table of chemicals and recommended doses.

Abstract: An historical reminder of the evolution of control of leaf spot diseases. The fungistatic effect of mineral oil was discovered in 1952. The first aerial spraying was performed in 1967. Systemic fungicides were then used. Resistance appeared in 1980. New control strategies were devised with research and development work by IRFA. The Plant Protection...see more

Abstract: A trial in sandy soil on the southern coast of Natal compared doses of 0, 200, 400, 600 and 800 g per plant per year of a nitrogenous fertilizer called LAN, containing 28% N. The 200 g application (56 g N) was effective. The nitrogenless control yielded 44.5 t/ha in the first two cycles. The 200 g application yielded 50.8 t/ha; there were no signif...see more

Abstract: The study was carried out in deep, black soil in the Jalgaon district where cultivation of Cavendish "nain" is well-developed. Treatments combined doses per plant of 100, 200 and 300 g of nitrogen, 20, 40 and 80 g of phosphorus and 100, 200 and 400 g of potassium. Effects on a 453-461 long first cycle were fairly small: average bunch weight varied ...see more

Abstract: The following species were observed at the start of the experiment: Helicotylenchus multicinctus, Rotylenchus reniformis, Meloidogyne incognita and M. arenaria. There were extremely small numbers of Radopholus similis. Two nematicides were compared: Nemacur 10% (phenamiphos) and Nemagon 88% EC (DBCP). In two treatments (3 and 4), the soil was...see more

Abstract: Study on the minimum ethylene treatment time at an appropriate temperature to initiate ripening. The MTT (minimum treatment time) was determined at ethylene doses of 1, 10, 100 and 1000 ppm and at temperatures of 20, 25 and 30ŒC. At 20ŒC, durations of less than 3 hours had no effect, whatever the dose, but durations were shorter (less than 2 hours)...see more

Abstract: A trial was performed at Mondouri in West Bengal from 1979 to 1981. The effect of NPK was examined on the growth, flowering, yield and quality of cv Giant Governor Cavendish banana. Three fertilizer/plant levels were tested; urea; 0 (N0), 120 (N1) and 240 g (N2); single superphosphate: 0 (P0), 45 (P1) and 90 g (P2); potassium chloride: 0 (K0), 240 ...see more

Abstract: Over 12,000 tonnes of bananas are produced annually (1983) in the Carnarvon zone in western Australia. Plantations are concentrated on alluvial soil with a high pH along Gascoyne River. The climate is dry (precipitation 253 mm per year) and cool (June-August). Leaf analyses in 58 plantations revealed general zinc deficiency and frequent copper and ...see more

Abstract: A trial on the fertilizer requirement of 'Robusta' banana was conducted at the Horticultural Research Station, Periyakulam, Tamil Nadu, with three levels in each of N, P2O5 and K2O. The results indicated that the plants which received 100 kg N, 40 kg P2O5 and 400 kg K2O per acre applied in three split doses produced bunches that were significantly ...see more

Abstract: A study on the effect of different methods and time of application of fertilizers conducted on 'Basrai' banana at the Banana Research Station, Yawal in Maharashtra State showed that the application of fertilizers at 10 cm depth by ring method is superior to 20 cm depth: the days required for flowering were reduced by 6.1 days and the days required ...see more

Abstract: The effect of association of Azotobacter culture with nitrogenous fertilizer (urea) on the growth and yield of 'Basrai' banana was studied at Banana Research Station, Yawal during 1976-79. The results indicated that the increasing levels of nitrogen with or without Azotobacter culture application had no influence on the growth and yield of bana...see more

Abstract: Treatments comprised fruits picked green at a normal stage of development; they were washed and treated by Bavisitine fungicidal dip. Treatments were: soaking in Ethrel at various concentrations; control: fruits soaked in water. Control fruits turned yellow in 6 days. The 250 ppm treatment had little effect. The other treatments accelerated color d...see more

Abstract: This study was carried out in a banana plantation in the Guápiles area of Costa Rica, where mean annual rainfall is around 3.830 mm and mean annual temperature is about 25,7°C. Plain urea (46% N) and sulphur-coated urea (38,3% N and 14% S) fertilizers were tested at levels of 0, 16, 31, 47, 68, 136, 205, 272, 341 and 409 kg N/ha and applied in inte...see more
