Sawi khususnya sawi hijau merupakan salah satu jenis sayuran daun, yang banyak dikosumsi oleh masyarakat Indonesia.Tanaman ini sangat berpotensi sebagai penyedia unsur–unsur mineral penting yang dibutuhkan oleh tubuh kita, karena nilai gizinya tinggi.  Pertumbuhan tanaman sawi dipengaruhi oleh jenis pupuk yang digunakan, baik itu pupuk organik ataupun pupuk an organik. Tujuan dari penelitian ini adalah untuk menguji pertumbuhan dan hasil tanaman sawi dengan pemberian macam pupuk kandang; untuk menguji pertumbuhan dan hasil tanaman sawi dengan pemberian pupuk Nitrogen; untuk menguji pertumbuhan dan hasil tanaman sawi dengan pemberian kombinasi macam pupuk kandang dan pupuk Nitrogen.Percobaan ini disusun secara faktorial dalam Rancangan Acak Kelompok (RAK), terdiri dari dua faktor yaitu  Perlakuan macam pupuk kandang dengan  2 level dan perlakuan pupuk nitrogen dengan 4 level.  Masing-masing kombinasi perlakuan diulang tiga kali dan setiap kombinasi perlakuan terdiri 2 (dua) tanaman sample. Faktor I: Macam pupuk kandang (K1 :kandang sapi dan K2 : kandang kambing).  Faktor II :Pupuk Nitrogen {N1: 50 gr/m2(4.50 gr/tan ); N2 : 75 gr/m2  ( 6,75 gr/tan ); N3 : 100 gr/m2 (9,00 gr/tan ); N4 : 125 gr/m2 (11,25 gr/tan)}.  Sehingga terdapat delapan (8) kombinasi perlakuan.  Pengamatan yang dilakukan pada penelitian terdiri dari panjang tananmn; jumlah daun dan berat segar tanaman. Hasil penelitian menunjukkan bahwa terdapat interaksi yang nyata pada perlakuan kombinasi macam pupuk kandang dan pupuk Nitrogen terhadap variabel jumlah daun umur 14 HST dan berat basah tanaman. Hasil terbaik ditunjukkan oleh perlakuan kombinasi K2N4.Perlakuan macam pupuk kandang berpengaruh sangat nyata terhadap pertumbuhan panjang tanaman umur 14 HST dan berat basah tanaman, sedang pertumbuhan jumlah daun berbeda nyata umur 14 HST.Hasil terbaik ditunjukkan oleh perlakuan pupuk kandang kambing (K2).Perlakuan pupuk Nitrogen berpengaruh sangat nyata terhadap semua variabel pengamatan.Hasil terbaik ditunjukkan oleh perlakuan N4.   Kata Kunci :  Tanaman Sawi; Pupuk Organik; Pupuk Nitrogen

A field experiment was conducted at Karangploso Research Station to investigate the effect of NPK fertilizer added with biofertilizer containing of N fixing and P solubilizing bacteria plus green manure of C. juncea on nutrient uptake and growth of sugarcane (Saccharum officinarum L.). The experiment had 10 treatments: (1) 100% of recommended fertilizer (RF), (2) 100% RF + biofertilizer, (3) 75% RF + biofertilizer, (4) 50% RF + biofertilizer, (5) 100% RF + C. juncea, (6) 75% RF + C. juncea, (7) 50% RF + C. juncea, (8) 100% RF + biofertilizer + C. juncea, (9) 75% RF + biofertilizer + C. juncea, (10) 50% RF + biofertilizer + C. juncea. The ten treatments were arranged in Randomized Block Design with three replications. Results showed that the nutrients uptake attributes (N, P and K) and growth of sugarcane was affected by biofertilizer and C. juncea. The best treatment of the results was combination of biofertilizer and C. juncea with 100% rate of recommended fertilizer of NPK gave the highest of N uptake and length of stalk.

The aim of research is to test the combination of organic fertilizer and NPK fertilizer, test organic fertilizer, test NPK fertilizer that is suitable for the growth and yield of sweet corn. This research method using Randomized Block Design (RAK) arranged factorial consists of two factors, namely Organic Fertilizer (cage) with 3 levels of treatment (K) and NPK Fertilizer with 3 levels of treatment (M). Each treatment was repeated 3 times and each treatment combination consisted of two sample plants. The results of this study showed that the overall treatment of the combination of organic fertilizer and NPK fertilizer on the growth and yield of sweet corn plants did not show a real effect. Separately the treatment of organic fertilizer gave a very real effect on all observation variables, the average organic fertilizer as much as 17.5 tons / ha or 1.5 kg / tan (K3) gave the highest growth and yield of sweet corn compared to other treatment, Separately the treatment of NPK fertilizer gave a very real influence on all observation variables, the average NPK fertilizer with a composition of 450 kg Urea + 150 kg TSP + 75 kg KCl) / Ha or 9 g + 3 g + 1.5 g / tan (M3) gives the highest growth and yield of sweet corn compared to other treatments. Person.

The purpose of this study was to determine the extent of the effect of the use of fertilizer doses NPK compound on the growth and yield of red spinach (Amaranthus tricolor L.), This research method used a Randomized Block Design (RAK) consisting of six (6) treatments with three (3) replications and two (2) sample plants. The treatment was given, namely the dose of NPK Compound Fertilizer which consisted of six (6) doses, A = No NPK Compound Fertilizer (Control), B = NPK Compound Fertilizer 100 kg/Ha (0.05 gr/tan = 0.5 gr/ 10 tons/polybag), C = NPK Compound Fertilizer 200 kg/Ha (0.10 gr/tan = 1.0 gr/10 tons/polybag), D = NPK Compound Fertilizer 300 kg/Ha (0.15 gr/tan = 1.5 gr/10 tons/polybag), E = NPK Compound Fertilizer 400 kg/Ha (0.20 gr/tan = 2.0 gr/10 tons/polybag) and F = NPK Compound Fertilizer 500 kg/Ha ( 0.25 gr/tan = 2.5 gr/10 tons/polybag), for analysis and assisted by using Excel. Research Results There was a significant effect on the observed variables of plant height, number of leaves and wet weight of red spinach plants due to the treatment of using various doses of NPK compound fertilizers and effective (appropriate) doses or optimum doses of NPK compound fertilizers during growth and yield of red spinach plants. The dose of NPK compound fertilizer treatment was 300 kg/Ha (0.15 gram/plant), while the maximum dose was indicated by the treatment dose of NPK compound fertilizer 500 kg/Ha (0.25 gram/plant), because statistically both treatments of compound fertilizer dose The NPK was not significantly different.

Garbage is a very large natural resource originating from housing and markets which ultimately waste becomes an important problem for densely populated urban areas if not utilized properly. Composting is basically an effort to activate microbial activities in order to accelerate the decomposition process of organic matter. The result of the reshuffle is called compost which is used as fertilizer that can provide nutrients for plants and improve soil fertility.)This activity is the implementation of appropriate technology in the mass composting of urban organic waste, especially in the empowerment of urban agricultural land (urban faming) which is carried out in the RW area. 02 Kalirungkut Village, Rungkut District, Surabaya City.The models offered to solve the problem of urban organic waste for partners are: 1). Help prepare assistance to improve expertise and skills in the management of urban organic waste mass composting; 2). Provide support in mobilizing community participation so that they consciously and voluntarily understand waste problems in order to become compost products that are beneficial for the cultivation of productive plants and greening the surrounding environment; The results of the implementation of this appropriate technology show that there is awareness of community participation in waste management by implementing the 3R (reduce, refuse, recycle) aimed at reducing the amount of waste starting at the source by sorting household waste in the form of organic waste and inorganic waste. With the urban agriculture movement, it can be an alternative to maintain family food security, besides being able to make a major contribution in providing green open space
