“…Peran besar daun dalam pertumbuhan tanaman menyebabkan terjadinya perbedaan produksi biomassa tanaman karena adanya perbedaan kemampuan daun melakukan fotosintesis untuk menghasilkan biomassa tanaman. Berkaitan dengan peran besar daun dalam kehidupan tanaman, luas daun menjadi salah satu parameter penting untuk mengetahui pertumbuhan tanaman sehingga diperlukan teknik pengukuran yang cepat, tepat dengan metode yang mudah, akurat, murah dan non destruktif [6].…”

Tujuan dari penelitian ini adalah untuk mengetahui perbandingan luas daun sawi caisim dari beberapa dosis nutrisi menggunakan software ImageJ. Dalam perhitungan luas daun menggunakan objek referensi sebagai perbandingan dalam input nilai luas daun dalam bentuk pixel yang kemudian diubah dalam bentuk centimeter. Setelah itu, citra gambar diubah ke dalam bentuk citra biner (0 dan 1). Kemudian tahap akhirnya dengan memilih gambar daun untuk mengetahui luasannya. Pada penelitian ini proses pengambilan gambar dilakukan dua kali untuk melihat tingat error pada pengambilan pertama dan kedua. Metode pengukuran luas area daun yang diusulkan mendapatkan tingkat akurasi dan presisi yang tinggi sehingga dapat menghemat waktu, tenaga, serta biaya. Pengujian menggunakan ANOVA mendapatkan hasil tidak berbeda nyata sehingga pengambilan gambar sebanyak apapun tidak akan berpengaruh pada perhitungan luas area daun.

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.

The problem of severe weed infestation often arises during the early phases of establishment of oil palm field due to the spacing requirement and growth habit of young oil palm plantation until later years when the canopy closes. This study was conducted at Ala, Akure-North Local Government Area, Ondo State, Nigeria, to investigate the composition of weed species and their distribution in fruit vegetable-juvenile oil palm intercrop. The fallow alleys within the immature oil palm were intercropped with 2 accessions of tomato (NGB 01665 and NG/AA/SEP/09/053) and eggplant (NGB 01737). The sampling of the weed species was carried out with a quadrat (0.25 m2). Weed species parameters and the Diversity Index (D) were quantitatively analyzed. The results revealed that members of Asteraceae and Poaceae gave the highest weed species at 3 and 6 weeks after intercropping (WAI) (17.857% and 19.04%) respectively. A total of 23 and 16 were found at 3 and 6 WAI, while the least diversity index of 0.734 was recorded in the immature oil palm/tomato (NGB 01665) plot at 6 WAI. Farmers should be persuaded to simultaneously intercrop fruit vegetables within the alley of juvenile oil palm, particularly at the earlier years prior to closure of the oil palm canopy.
