Lahan kering yang kritis dapat direhabilitasi dengan menerapkan pola agroforestri. Lahan kering mempunyai masalah dengan kesuburan yang rendah serta rentan erosi. Agroforestri dapat meningkatkan keberhasilan penanaman sekaligus mendukung upaya swasembada pangan. Pemilihan jenis tanaman akan meningkatkan keberhasilan penanaman sekaligus memperoleh hasil antara bagi petani. Penelitian ini bertujuan untuk mengetahui produktivitas masing-masing jenis tanaman penyusun pada sistem agroforestri manglid. Pengamatan menggunakan eksperimental design dengan membuat plot percobaan penanaman manglid dan tanaman semusim jenis kedelai dan jagung. Penelitian menggunakan rancangan percobaan acak lengkap kelompok (RCBD) yang terdiri dari perlakuan jarak tanam manglid yaitu: 3 mx3 m (J1), 3 mx 4 m (J2), 3 mx 5 m (13), 3 mx 6 m (J4). Setiap perlakuan, terdiri dari 42 tanaman (7x6) serta 3 ulangan, sehingga total tanaman manglid sebanyak 504 tanaman. Tanaman kedelai ditanam selang-seling dengan jagung. Kedelai ditanam dilarikan manglid sedangkan jagung ditanam di antara tanaman manglid. Hasil penelitian menunjukkan bahwa perlakuan jarak tanam manglid belum memberikan perbedaan pertumbuhan sampai umur 9 bulan. Tanaman kedelai yang ditanam dalam larikan tanaman pokok masih mampu memberikan produktivitas 0,190-0,529 ton/ha, jagung yang ditanam di antara tanaman manglid mampu memberikan produktivitas tertinggi sebesar 1,224 ton/ha. Pola agroforestri yang memberikan pendapatan tertinggi bagi petani diperoleh pada pola tanam manglid+jagung manis+kedelai dengan jarak tanam 3m x 6m.Plant Growth of Crop and Manglid Species (Magnolia champaca) on the Agroforestry PatternAbstractCritical dry land can be rehabilitated by applying agroforestry patterns. Dry land has problems with low fertility and susceptible to erosion. Agroforestry can increase the success of planting as well as support food self-sufficiency efforts. Selection of crops will increase the success of planting as well as to obtain intermediate results for farmers. This study aimed to determine the productivity of each plant species on the manglid agroforestry system. The observations used experimental design by making experimental plots of manglid planting and crops of soybean and maize species. The study used a complete Randomized Block Design (RCBD) consisting of treatment of manglid spacing:3 mx3 m (J1), 3 mx 4 m (J2), 3 mx 5 m (53), 3 mx 6 m (14). Each treatment consisted of 42 plants (7x6) and 3 replications, yielding a total of 504 manglid plants. Soybean crops was planted alternately with corn. Soybeans were grown in manglid while corn was planted among manglid plants. The results showed that treatment of manglid plant spacing did not show a difference growth until the age of 9 months. Soybean crops grown in the staple of staple crops were still able to provide productivity of 0.190-0.529 ton/ha, maize grown among manglid crops was able to provide the highest productivity of 1,224 ton/ha. Agroforestry pattern that gives the highest income for farmers was obtained on the pattern of planting manglid + sweet corn+soybean with plant spacing of 3m x 6m.

ABSTRAK<br />Amrasca biguttula (Ishida) adalah serangga hama pengisap daun<br />yang sangat potensial menurunkan produktivitas kapas. Pengendaliannya<br />secara kimiawi menimbulkan banyak masalah lingkungan, seperti<br />pencemaran dan peningkatan resistensi hama terhadap insektisida kimia<br />sintetis. Salah satu solusi dalam masalah tersebut adalah penggunaan<br />varietas tahan (resisten) yang juga merupakan bagian dari pengendalian<br />hama terpadu (PHT) pada kapas. Penelitian ketahanan beberapa aksesi<br />kapas terhadap A. biguttula (Ishida) dilakukan di Kebun Percobaan Balai<br />Penelitian Tanaman Tembakau dan Serat di Asembagus, Situbondo, mulai<br />Januari hingga Desember 2006. Tujuannya adalah untuk mengetahui<br />ketahanan beberapa aksesi kapas terhadap serangan hama pengisap daun,<br />A. biguttula. Sebagai perlakuan adalah 30 aksesi kapas yang ditanam<br />dalam plot berukuran 10 m x 3 m, dengan jarak tanam 100 cm x 25 cm,<br />satu tanaman per lobang. Setiap aksesi disusun dalam rancangan acak<br />kelompok dengan tiga kali ulangan. Parameter yang diamati adalah jumlah<br />nimfa A. biguttula per daun, jumlah bulu daun per cm 2 luas daun, dan<br />posisi bulu terhadap lamina (tegak/rebah), serta skor kerusakan tanaman.<br />Hasil penelitian menunjukkan bahwa setiap aksesi kapas berpotensi<br />terserang A. biguttula, meskipun tingkat populasi hama ini tidak<br />menunjukkan perbedaan nyata antar aksesi. Terjadi korelasi negatif (R 2 =<br />0,2425) antara jumlah bulu daun dan populasi nimfa A. biguttula dan<br />antara jumlah bulu daun dan skor kerusakan tanaman (R 2 = 0,2027).<br />Berdasarkan jumlah bulu daun, aksesi kapas yang termasuk kategori<br />sedikit berbulu dengan kriteria ketahanan sedikit tahan adalah: AC 134,<br />Stoneville 7, Fai Nai, SHR, CRDI-1, Kanesia 5, Kanesia 8, dan Kanesia 9.<br />Sedangkan aksesi lainnya termasuk kategori tidak berbulu dan peka<br />terhadap serangan A. biguttula.<br />Kata kunci : Kapas, Gossypium hirsutum, aksesi, hama, Amrasca<br />biguttula (Ishida), toleran, peka, kerusakan, Jawa Timur<br />ABSTRACT<br />Resistance of several cotton accessions to sucking insect<br />pest, Amrasca biguttula (Ishida)<br />Amrasca biguttula (Ishida) is a sucking insect pest which potentially<br />reduces cotton productivity. Its chemical control often cause environ-<br />mental problems mainly air pollution and increase of pest resistance to<br />certain chemical insecticides. One solution can be used to solve these<br />problems is by using resistant variety that is also an integral part of the<br />integrated pest management (IPM). Study on the resistance of several<br />cotton accessions to sucking insect pest, Amrasca biguttula (Ishida) was<br />conducted at the Experimental Station of the Indonesian Tobacco and<br />Fiber Crops Research Institute (IToFCRI) in Asembagus, Situbondo, East<br />Java, from January to December 2006. The objective of the study was to<br />find out the resistance of cotton accessions to sucking insect pest. Thirty<br />accessions of cotton were used as treatment and were planted in plots 10 m<br />x 3 m with plant spacing 100 cm x 25 cm, one plant per hole. Each<br />accession was arranged in a randomized block design with three<br />replications. Parameters observed were number of nymph of A. biguttula,<br />number of leaf hair, leaf hairs position (erect or lie down), and score of<br />damage. The result showed that every accession of cotton can be attacked<br />by A. biguttula although the insect population was not significantly<br />different among accessions. There is negative correlation (R 2 = 0.2425)<br />between number of leaf hair and population of A. biguttula and between<br />number of leaf hair and score of plant damage (R 2 = 0.2027). Accessions<br />that categorized as lightly hairy and moderately resistant to A. biguttula<br />were AC 134, Stoneville 7, Fai Nai, SHR, CRDI-1, Kanesia 5, Kanesia 8,<br />and Kanesia 9, while the others were categorized as glabrous and<br />susceptible to the sucking pest.<br />Key words: Cotton, Gossypium hirsutum, accession, insect pest, Amrasca<br />biguttula (Ishida), tolerant, sensitive, damage, East Jav

The research was performed with the aim of examining and obtaining appropriate combinations of plant spacing and planting model for red chili (Capsicum annuum L.) and shallot (Allium ascalonicum L.) plants in saline soil conditions. The utilized design on this research was randomized block design. This research consists of 6 combinations that are repeated 4 times, resulting in 24 experimental units. Based on the research, it was found that the treatment of multiple cropping of red chilies i.e. 2 rows of shallot plants between rows of red chilies have land equivalence ratios (LER) greater than 1, being 1.32 and 1.41, which indicates that the treatment of multiple cropping leads to higher land effectiveness.
