This study was conducted to evaluate the productivity of cowpea (Vigna unguiculata (L.) Walp) in the middle plains. Research was conducted in the middle plains in Kampung Cisasah Rawasari, Ciomas, Bogor, West Java. Planting was done in April 2016 to July 2016. The research used Completely randomized design (RKLT) factor. There are five standard of treatment used is KT-1, . The treatment was repeated four times so that there are 20 experimental unit. Data analysis using F test and if the results are real, then the test continued with DMRT (Duncan's Multiple Range Test) at 5% level. Do also test multiple variables correlation with productivity. The results showed that the treatment varieties significant effect on variables leaf area, number of pods per plant, weight of dry beans per plant, weight of dry pods per plant, seed yield, pod yield, as well as the treatment of varieties have real impact on the ability to grow crops and conductance plants. The characters are positively correlated and highly visible on the productivity of cowpea is a leaf angle to photosynthesis, leaf angle of the conductance, photosynthesis against conductance, number of pods on the dry weight of pods, pods of the dry weight of the seed, pod length to the number of seeds per pod, dry weight the seed pods dry weight, number of pods on the seed yield, number of pods on pod yield, dry weight of the seed pod yield.

Penelitian ini dilakukan untuk mengevaluasi produktivitas kacang tunggak (<em>Vigna unguiculata</em> (L.) Walp) pada dataran menengah. Penelitian dilaksanakan pada dataran menengah di Kampung Cisasah Rawasari, Ciomas, Kabupaten Bogor, Jawa Barat. Penanaman dilakukan pada bulan April 2016 hingga Juli 2016. Penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) satu faktor. Terdapat lima taraf perlakuan yang digunakan yaitu KT-1, KT-2, KT-6, KT-8 dan KT-9. Perlakuan diulang sebanyak empat kali sehingga terdapat 20 satuan percobaan. Analisis data mengunakan uji F dan apabila hasilnya nyata maka pengujian dilanjutkan dengan uji DMRT (<em>Duncan’s Multiple Range Test</em>) pada taraf 5%. Dilakukan juga uji korelasi beberapa peubah dengan produktivitas. Hasil penelitian menunjukkan bahwa perlakuan varietas berpengaruh sangat nyata terhadap peubah luas daun, jumlah polong per tanaman, bobot biji kering per tanaman, bobot polong kering per tanaman, hasil biji, hasil polong, serta perlakuan varietas berpengaruh nyata terhadap daya tumbuh tanaman dan konduktansi tanaman. Karakter yang berkorelasi positif dan sangat nyata terhadap produktivitas kacang tunggak adalah sudut daun terhadap fotosintesis, sudut daun terhadap konduktansi, fotosintesis terhadap konduktansi, jumlah polong terhadap bobot kering polong, jumlah polong terhadap bobot kering biji, panjang polong terhadap jumlah biji per polong, bobot kering polong terhadap bobot kering biji, jumlah polong terhadap hasil biji, jumlah polong terhadap hasil polong, bobot kering biji terhadap hasil polong.
