Abstract

Soybean is one of the food commodities, which contains vegetable protein, carbohydrates and fat, hence it is necessary to complement the nutrition. Demand consumption of soybean higher with increasing population annually, the production of soybean is still sufficient to complete the increasing of demand. Therefore, the increasing of soybean production has to be considered to decrease the dependency on imported. Soybean production can be increased by the cultivation technique. In this method, the present of weed should be concerned. Weed can reduce the quality and quantity of soybean. The research was done at Kebun Pendidikan, Penelitian dan Pengembangan Pertanian (KP4) Gadjah Mada University which located at Kalitirto, Berbah, Sleman, Yogyakarta, Indonesia. This research started on November 2015-April 2016. The research aims to identify the effects of weed on the growth analysis of several soybean cultivar. This field research is arranged using spit plot with three blocks as the repetition where the main-plot is the weed treatments andthose are weed-free, weeding in a critical period, and weedy. Sub plot is the soybean cultivars which are Anjasmoro, Argomulyo, Burangrang, Gema, Gepak Kuning, Kaba, and Wilis. The research’s result show the weed treatments would effect no significant difference in the leaf area index, net assimilation rate, crop growth rate (3 to 6 weeks after planted/WAP), specific leaf weight, and leaf area ratio (3 WAP). Which affects are the crop growth rate (6 to 9 WAP) and leaf area ratio (6 and 9 WAP)

Abstract

The initial step in the assembly of hybrid maize is the formation of inbred lines. This research aims to see the differences in phenotypic characters and to determine the percentage of inbreeding depression between selfing and open-pollinated plant populations. Research activities have been carried out in the cornfield of Nagari Sitiung, Sitiung District, Dharmasraya Regency, West Sumatra. The materials used were F2 maize selected from a cross between BSM0729S3 and BAP27799 and maize S4 from BSM0729S3 (female parent). The research was conducted using a T-test, namely open-pollinated (T1) and selfing (T2). After the T-test was performed, the percentage of inbreeding depression was calculated for each observation variable. The results showed that the open-pollinated treatment was significantly different from the selfing treatment on the variables of plant height, ear height, anthesis time, silking time, harvesting age, ear weight per plant, length and diameter of the ear, kernel row number, and intensity of anthocyanin staining on hair, tassels, and roots. The magnitude of the decrease in vigor in the open-pollinated treatment was smaller than the selfing treatment on all observed variables except for the anthocyanin intensity variable in tassel and roots. Therefore, it is necessary to do further selfing on the S4 population to obtain uniform pure lines and mass selection on the F2 population to produce a uniform maize population.
