Abstract

As a staple food, rice can be used as a bio fortification. For this necessity, Indonesian Agency for Agriculture Research and Development (IAARD) developed rice variety which was rich of Zn content to overcome child stunting. To understand the panicle branching behavior of Inpari IR Nutri Zinc, we collected panicle branching data from different sites and agronomical practices. Data were collected from three locations in West Java, i.e Cianjur, Majalengka, and Ciamis during May until October 2020. Among sites showed a significant differences of panicle branching. The best performance of Inpari IR Nutri Zinc panicle branching was showed at Majalengka rather than Ciamis and Cianjur. It was predicted because of temperature differences, as Cianjur’s was higher than those Majalengka’s and Ciamis’. Based on planting space, L5 was better than that L2 in number of grains per panicle, number of primary branches, number of secondary branches, total length of primary branches, and number of filled-grain per panicle characters. Meanwhile, L2 in Majalengka and Ciamis showed higher value in three panicle branching characters. Further, the L2 in Majalengka showed higher value and significantly difference than that in Ciamis in seven panicles branching characters bio pesticide application also affected some panicle branching characters significantly.

Values in the same row which followed by the same letter was not different based on DMRT test on 5% of alpha; CV = coefficient of variation; PL = panicle length; MAL = main axis length; number of node (NN) = node number; NGP = number of grains per panicle; NPB = number of primary branches; NSB = number of secondary branches; PBL = primary branch length; SBL = secondary branch length; number of grains per primary branches (NGPB) = number of grains on primary branch; number of grains per secondary branches (NGSB) = number of grains on secondary branch; total length of primary branches per panicle (TLPB) = total length of primary branches; total length of secondary branches per panicle (TLSB) = total length of secondary branches; SBperPB = number of secondary branches per primary branch; TGSB =; number of filled-grains per panicle (NFG) = number of filled-grains; number of unfilled-grains per panicle (NUFG) = number of unfilledgrains

Summary

Introduction

Rice was consumed by a major of civilization in the world. Beside as a source of energy, rice can be functioned as a source of micro-nutrients which are needed by the human being. The micro-nutrients contained in rice were iron (Fe), Zinc (Zn) and various vitamins and minerals, but rice does not supply these vitamins and minerals adequately [1]. It was reported that 2.7 billion people in the world were suffer from Zn deficiency [2]. The researchers and breeders gave the opinion of using staple food as a tool to overcome the zinc deficiency through bio fortification [4].
