Abstract

This study aims to determine the performance yield component of sweet corn and weed density due to different kinds of fertilizer treatments. This study uses a randomized complete block design (RCBD) in factorial patterns with two factors. The first factor is biofertilizer-Arbuscular mycorrhiza fungi (biofertilizer-AMF) which consists of four levels, namely without biofertilizer-AMF (A0), biofertilizer-AMF 5 g/planting hole (A1), biofertilizer-AMF 10 g/planting hole (A2), biofertilizer-AMF 15 g/planting hole (A3). The second factor is cow manure fermented consisting of three levels, namely without cow manure (B0), cow manure 5 tons ha-1 (B1), cow manure 10 tons ha-1 (B2) with 3 replications so that there are 36 experimental units. The variables observed in this study were: cob length (cm), cob diameter (cm), number of seed rows, cob weight with husk (g), cob weight without husk (g) productivity of sweet corn plants (ton ha-1) and kinds of weeds and their absolute density. The results showed that the highest average corn crop productivity was obtained in the treatment without biofertilizer-AMF and cow manure fermented 10 tons ha-1 (A0B2) as 8.52 tons ha-1. If the combination of treatments contained biofertilizer-AMF and cow manure fermented, the highest average productivity of sweet corn was obtained in the treatment of biofertilizer-AMF 5 g/planting hole and cow manure fermented 10 tons ha-1 (A1B2) as 7.19 tons ha-1. The highest weed density from broadleaf is H.capitata (34.167%), from grasses is I.cylindrica (32.432%) and from sedges is Cyperus sp (30.21%).

Highlights

Sweet corn is one type of plant that is widely cultivated in the tropics and harvested young which has high economic value because the price is quite expensive

Summary

Introduction

Sweet corn is one type of plant that is widely cultivated in the tropics and harvested young which has high economic value because the price is quite expensive. According to [1] the advantage of producing sweet corn is a short harvest time and high selling prices. Sweet corn has relatively high nutritional and sugar content, so it is very popular with people both in rural and urban areas. The difference in taste between sweet corn and regular corn lies in the sugar content. [2], satated that sweet taste in sweet corn occurs because carbohydrates in corn kernels contain reducing sugars (glucose and fructose), sucrose, polysaccharides and starch. The effort to cultivating sweet corn cannot be separated from obstacles which include limited soil fertility and the presence of weeds that grow in the planting area.
