“…Daya berkecambah benih varietas anjasmoro lebih tinggi dibandingkan dengan varietas biosoy 2. Hal ini tidak sesuai dengan hasil yang diperoleh (Kilkoda et al, 2015) yaitu benih yang memiliki ukuran besar menghasilkan tinggi tanaman, jumlah daun, luas daun dan jumlah polong yang lebih tinggi dibandingkan dengan benih yang berukuran kecil dan sedang. Ukuran benih merupakan salah satu faktor yang menentukan keberhasilan suatu benih untuk dapat tumbuh.…”

Penurunan hasil produksi kedelai dapat disebabkan karena adanya faktor internal yaitu mutu benih, untuk itu perlu dilakukan pengujian mutu benih sebelum benih kedelai ditanam di lapangan. Pengujian daya kecambah dan tetrazolium dapat dilakukan untuk mengetahui mutu benih kedelai. Penelitian ini bertujuan untuk mengetahui daya berkecambah dan viabilitas benih kedelai varietas anjasmoro dan biosoy 2 serta mengetahui korelasi antara uji tetrazolium (uji TZ) dengan uji daya berkecambah benih kedelai (Glycine max L.) varietas anjasmoro dan biosoy 2. Pengujian vigor benih yang dilakukan menggunakan 2 metode yaitu pengujian vigor dengan uji daya berkecambah dan pengujian vigor dengan uji TZ. Hasil uji TZ yang diperoleh menunjukkan bahwa benih kedelai varietas anjasmoro dan biosoy 2 merupakan benih yang viabel. Benih varietas anjasmoro memiliki persentase benih viabel sebesar 92.75% dan benih biosoy 2 82%. Pengujian daya berkecambah benih kedelai varietas Anjasmoro, ditemukan kecambah normal 80.75%, kecambah abnormal 12.25%, dan benih mati 7%. Sementara benih kedelai varietas Biosoy 2 ditemukan kecambah normal 41.25%, kecambah abnormal 40.75%, dan benih mati 7.72%. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa benih kedelai varietas anjasmoro memiliki viabilitas dan daya berkecambah yang lebih tinggi dibandingkan dengan benih kedelai varietas biosoy 2. Penelitian lebih lanjut tetang pengaruh waktu simpan terhadap mutu benih, akan sangat membantu dalam memahami waktu yang tepat untuk penyimpanan kedelai varietas Anjasmoro dan Biosoy 2.

“…Gulma adalah salah satu Organisme Pengganggu Tanaman (OPT) atau jasad pengganggu tanaman. Gulma merupakan tumbuhan yang mengganggu pertumbuhan tanaman atau merugikan kepentingan manusia sehingga manusia berusaha untuk mengendalikannya (Sembodo, 2010;Kilkoda, 2015). Nantasomsaran dan Moody (1993) melaporkan bahwa keberadaan gulma di pertanaman padi sawah dapat menurunkkan produksi padi hingga 10-40%.…”

Rice (Oryza sativa L.) is one of the primary food crop commodities in Indonesia. The need for rice is always increasing every year, so efforts are needed to increase rice production. One of the things that can inhibit the rice production was weeds. The first step to control weed was identifying the type of weeds. This study aims was to identify the dominance of weeds found in tidal paddy fields in Indragiri Hilir Regency. The study was conducted on tidal land owned by farmers in Indragiri Hilir Regency, Riau Province. The study was conducted at four locations, namely in the districts of Batang Tuaka, Keritang, Reteh, and Tembilahan Hulu. The research was carried out using a survey and exploration methods. The results revealed that 12 families consisted of 20 species of weeds in the tidal land rice plantations of Indragiri downstream. Based on the Taxonomy, there are seven species of monocot weeds and 13 dicotyledons. Based on the morphology, there are 12 species of broadleaf weeds, five species of grasses weeds, two species of fern weeds, and one species of Cyperaceae weeds. Ageratum conyzoides and Imperata cylindrica species are the most dominant weeds in rice plantations with an SDR (Summed Dominance Ratio) of 9.57% each.

“…Weeding regime is primarily aimed at suppressing the growth of weeds to the limits of economic damage (Barus, 2003). Research conducted by Widayat and Purba (2015), Kilkoda et al (2015) and Prayogo et al (2017) on rice and soybean plants proved that weed control efforts can increase yields. Understanding the types of weeds that are common in planted areas and the factors that cause the emergence of these weeds is important as preventive efforts to control weeds.…”

Centella (Centella asiatica L. Urban) originally is a wild plant that is being cultivated to be medicinal and cosmetics raw material. The process of centella cultivation is relatively easy and can be grown in a variety of altitudes. One obstacle in centella cultivation is weed growth. The proper handling of weeds in centella plantation requires data on the weed types and characteristics. This research aimed to determine the weed types and the amount of weed found in centella cultivation. Sampling was carried out purposively based on the presence of weeds in the cultivation area. Weed inventory was carried out using linear vegetation methods in 12 plantation beds of centella, with a size of 6 x 2 m2 each. Observations were made during weeding on one cropping season. Weed inventory was carried out by recording the number of species and number of individual weed and taking documentation of weeds that were recorded for identification purposes. Research data were analyzed by using vegetation analysis. The weed vegetation analysis on centella plantations showed that there were 35 species of weeds identified from 20 plant families. Cyperus rotundus L. dominates the weed vegetation in centella plantations because of its high adaptability and its allelochemical exudates. To sustainably cultivate the centella, proper techniques of weed controls need to be applied by considering the nature of Cyperus rotundus L.
