Uji Adaptasi Beberapa Varietas Tanaman Jagung (Zea mays L) pada Kondisi Defisiensi Hara P

Abstract

The objective of this research was to get variety that efficient in using Phosphor nutrient, adaptive and have high yield potention on deficiency P. This research was conducted in the village of Blang Cirih, District Peusangan Siblah Krueng Bireuen district from May to September 2015. This study the design was done by using Split Plot Design consists of two factors: the condition of P as the main plot and various corn varieties as subplots, then repeated three (3) times where treatment factors are as follows: 1. Conditions P (Petak Main) consists of P0 (condition deficient P) and P1 (condition not deficient P) (100 kg / ha SP36) and Children Petak (AP): Some varieties of maize which consists of 6 levels ie: V1: Bonanza varieties, V2: Royal Sweet varieties, V3: Bisma varieties,V4: Anoman 1 varieties, V5: Sukmaraga varieties, and V6: Arjuna varieties. The results showed that the growth and production of corn on the conditions of nutrient deficiency P very significant effect on all the observed variables except P content of leaves, harvest index and net assimilation rate. There are differences between the varieties of growth and production of Bonanza, Royal Sweet, Bisma, Anoman 1, Sukmaraga and Arjuna very significant effect on all parameters were observed except P content of leaves, harvest index and the rate of assimilation bersih.Varietas which has the highest production varieties are Anoman 1 and Arjuna. Deficiency of P gives the growth and production of different plants for each variety. Varieties that have been unable to adapt to the conditions of nutrient deficiency but varieties Anoman P 1 and Arjuna produce shelled weight higher than other varieties.
