Abstract

Superior varieties and local varieties of paddy fields have different physiological characters so when cultivated organically made possible the result would have been different. The purpose of this research is to know the relation between greenish of leaf, chlorophyll content and rate of photosynthesis as well as local and superior varieties on the yield and yield component. This research was carried out in the greenhouse of Agriculture Faculty, Gadjah Mada University Banguntapan Sleman, in October 2012 to February 2013. The experimental design was Completely Randomized Design (CRD) factorial, 2 factors of treatment and repeated 3 times. Factor I was kind of cultivation, namely organic cultivation and conventional cultivation. Factor II is a kind of rice varieties of rice field consists of 5 kinds of paddy rice varieties consisting of local varieties (mentikwangi, pandanwangi and cianjur) and superior varieties (IR64 and cisedane). The observed parameter includes the greennish of leaf 6, 8, and 10 weeks after planting (WAP), chlorophyll a, chlorophyll b, total chlorophyll, photosynthetic rate and yield and yield components. The results of this research show that the greennish leaf, level of chlorophyll a, chlorophyll b and total chlorophyll as well as the photosynthetic rate of rice fields cultivated organically lower than conventional cultivation. Number of total grain, grain percentage content and grain yield in organic cultivation are lower than conventional farming, but the weight of 1000 grains increased. Mentikwangi variety in organic cultivation the result is increased.

Abstract

Lahan pasir di wilayah yogyakarta sebagai lahan pertanian produktif memiliki peluang yang besar untuk budidaya tanaman pangan dan hortikultura. Penelitian dilakukan untuk mengetahui pengaruh tingkat kerapatan tanaman pagar jagung manis terhadap karakteristik perakaran tanaman kacang hijau. Penelitian dilakukan di lahan pasir pantai Samas Bantul pada Agustus sampai November 2016. Rancangan yang digunakan adalah rancangan faktorial multilokasi (oversite) dengan faktor pertama penggunaan tanaman pagar dan faktor kedua kultivar kacang hijau. Faktor pertama yaitu tanpa tanaman pagar, kerapatan tanaman pagar tinggi, kerapatan tanaman pagar rendah. Faktor kedua sebagai anak petak terdiri Vima 1 dan lokal Purworejo. Pengamatan yang dilakukan adalah analisis tanah, jumlah bintil akar, diameter akar, volume akar, panjang akar, dan luas permukaan akar. Hasil penelitian menunjukkan bahwa penggunaan tanaman pagar memiliki volume akar kacang hijau 2 MST, luas permukaan akar 4 MST, dan jumlah bintil akar kacang hijau 6 MST lebih tinggi dibanding tanpa tanaman pagar. Terdapat interaksi antara perlakuan kerapatan tanaman pagar dengan kultivar pada variabel jumlah bintil akar kacang hijau umur 2 MST, diameter akar 4 MST, dan panjang akar 4 MST
