<p>ABSTRACT</p><p><br />The objectives of this research was to study the effect of shade on growth and productivity of several indigenous vegetables. The research was conducted at Vegetable Garden, University Farm IPB, Darmaga from February until June 2009. This research was arranged in a Randomized Completely Block Design, 1 factor with 2 treatments, shading (N1) and no shading (N0). Result of the research showed that shading increased plant height, length of branch, leaf length and width of Daun Ginseng (Talinum triangulare); leaf diameter, leaf length and width, petiole length of Sambung Nyawa (Gynura procumbens); leaf length and width of Katuk ( Sauropus androgynus); leaf number of Kenikir (Cosmos caudatus), stem diameter of Kemangi (Ocimum americanum); plant height, length of branch, number of branch, leaf length and width of Pohpohan (Pilea trinervia). Shading also increased total fresh and dry weight/plant of Daun Ginseng; and total fresh/plant of Sambung Nyawa and Pohpohan plants. Productivity of Daun Ginseng and Pohpohan at shade field was better than at open field. Daun Ginseng, Sambung Nyawa, Kenikir, Kemangi and Pohpohan plants prefered growing at low light intensity (shade <br />plants).</p><p><br />Key words: indigenous vegetable, shading, growth, productivity</p>

Pupuk merupakan salah satu  faktor yang dapat mempengaruhi pertumbuhan dan produksi tanaman sayur. Penelitian ini bertujuan mempelajari pengaruh beberapa sumber pupuk organik terhadap pertumbuhan dan produksi hasil caisin, kangkung, pakcoi, dan selada. Penelitian ini dilakukan secara seri dengan empat tanaman sayur : caisin, kangkung, pakcoi, dan selada. Perlakuan menggunakan Rancangan Kelompok Lengkap Teracak sebanyak tiga ulangan yang terdiri dari sumber pupuk organik (pupuk kandang ayam, pupuk kandang sapi, kompos 20 ton ha-1 dan kontrol/tanpa penggunaan pupuk organik). Pertumbuhan dan hasil produksi tanaman sayur berpengaruh sangat nyata oleh pemberian pupuk organik, Perlakuan pemberian pupuk kandang ayam menghasilkan tinggi tanaman dan jumlah daun lebih banyak pada tanaman caisin, kangkung, dan selada. Pemberian pupuk kandang ayam juga menghasilkan berat batang dan berat akar tertinggi pada tanaman caisin, kangkung, dan pakcoi. Selain itu, pemberian pupuk kandang sapi memberikan panjang akar terbesar pada selada. Pupuk merupakan salah satu  faktor yang dapat mempengaruhi pertumbuhan dan produksi tanaman sayur.

<p style="text-align: justify;">Media selection is one of important factor for the growth and production of erected kidney bean (Phaseolus vulgarisL.). Utilization the waste media of white oyster mushroom (Pleurotus ostreatus) and waste media of paddy straw mushroom (Volvariella volvaceae), cow manure, and rice husk as plant growth media for kidney bean can be used for optimizing the utilization of local resources and minimizing environmental damage as well as to support the codification of GAP (Good Agricultural Practices) of kidney bean. The research was done from February until October 2011 in experiment field at Leuwikopo, IPB, Bogor. The experiment consisted of one factor and arranged in Randomized Complete Design with thirteen combinations from five kinds of <br />organic media component, they were soil, waste media of white oyster mushroom, waste media of paddy straw mushroom, cow manure, and rice husk with 1:1 ratio (v/v). The kidney bean showed good responses to the combination media treatment of cow manure, combination of soil and waste media of paddy straw mushroom, combination of soil, waste media of paddy straw mushroom, and cow manure, and combination of soil, waste media of paddy straw mushroom, cow manure, and rice husk. How ever the best result of kidney bean production was given from waste media of paddy straw mushroom treatment.</p><p>Keyword:  erected kidney bean, plant growth media, waste media of paddy straw mushroom, co w manure</p>

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.
