The influence of mulching on the consumptive use of water and yield of cotton (Gossypium hirsutum L.) [study conducted in the Philippines]
1982
Hechanova, R.F.
The objective of this study is to determine the water consumptive use of the crop as influenced by the application of rice straw mulch on three tanks, rice hull mulch on another three tanks, and three tanks that were unmulched. In this study better yields of cotton were obtained when rice straw mulch was applied during the medium or late planting dates when soil moisture content for crops are critical. The results indicate that mulching may reduce the consumptive use of cotton at the same time increase yield. The mean yield obtained in tons per hectare were 2.74, 2.50 and 1.91 for plants with rice straw mulch, rice hull mulch and without mulch, respectively. For complete growing season, the mean daily water consumption of the crop were 3.92 mm, 4.49 mm and 5.65 mm for plants with rice straw mulch, rice hull mulch and without mulch, respectively. The critical water demand was observed on the fourteenth week after planting. The highest rate of growth occurred at twelve weeks after planting
