The Cape gooseberry Production in Substrates Culture

Abstract

     Study of substrate culture on growth rate and productivity of cape gooseberry in hydroponic system. The experiments was conducted at Division of Pomology, Faculty of Agricultural Production, Maejo university, Chiang Mai province, were carry out of area 300 meter above sea level. There were separated in two experiments. The experiment 1 was evaluate the cape gooseberry seedling in 8 different substrate compositions, including coconut coir washed with calcium nitrate, coconut coir washed with water, coconut coir, coconut chip washed with calcium nitrate, coconut chip washed with water, coconut chip, sand, and rice husk charcoal. It was found that the growth rate of cape gooseberry was planted in coconut coir washes with calcium nitrate was heigh of the tree as 78.22 cm and the canopy diameter of 44.80 cm. And also cape gooseberry were grown in coconut chip washed with water and coconut chip washed with calcium nitrate were significate difference in other treatments as 4.43 and 4.38 g. respectively. In the experiment 2 was studied on the best of substrate culture from experiment 1 and mixed one, including coconut coir, coconut chip, sand + coconut coir (1:1), sand + coconut chip (1:1), sand + rice husk charcoal (1:1), rice husk charcoal + coconut coir (1:1), rice husk charcoal + coconut chip (1:1), coconut coir + sand + rice husk charcoal (1:1:1), and coconut chip + sand + rice husk charcoal (1:1:1). The result showed that cape gooseberry planted in the ratio of substrate culture of sand + rich husk charcoal (1:1) in the first month was height of tree as 15.12 cm and canopy diameter as 15.5 cm. For the growth rate in second month after planted, there was no difference of the height and canopy diameter of all treatments. The highest of berry weight was planted on sand + coconut ship (1:1) was 6.31 g, which no significantly different from that of coconut coir + sand + rice husk charcoal (1:1;1) and sand + coconut coir (1:1) were 5.89 and 5.42 g respectively.
