Abstract

Studies to Influences of Irrigation Regimes of cape gooseberry, by conducting an experiment in the area of a farmer’s plot area of royal project development center Kae Noi, Mueang Na Subdistrict, Chiang Dao District Chiang Mai Province. using a completely randomized block design (RCBD) with four replicates, with 4 methods of irrigation, (i) the method which the local farmers usually use (control), (ii) irrigated everyday to the crop evapotranspiration (ETc), (iii) irrigated when soil moisture reduced by 30% of AWC (AWC 30%), and (iv) when soil moisture reduced by 50% of AWC (AWC 50%). Result of the studies showed that, 30 days after transplanting in all 4 methods did not differ statistically. But at the age of 35 to 70 days, that the four methods were statistically different. Method 2 (ETc) resulted in cape gooseberry growing at the highest plant height. And produce the most yield throughout the growing season. But when considering yield quality (fruit weight, diameter, titrable acidity (TA), total soluble solid (TSS), and vitamin C content). It was found that the irrigation management of four methods resulted in no differences in the quality of the cape gooseberry. The above study indicated that all four irrigation methods were able to produce the same good quality. All experiments showed that daily watering according to plant evaporation rate data resulted in higher growth and yield of cape gooseberry. The reason is because water is very important to the growth of cape gooseberry. When plants receive sufficient or appropriate water for the period of growth, it will result in higher growth and yield.
