Penelitian ini bertujuan untuk mengetahui peningkatan produktivitas padi sawah (Oryza sativa L.) melalui penerapan beberapa jarak tanam dan sistem tanam. Penelitian ini dilaksanakan di lahan sawah Desa Tanjung Mulia Kecamatan Tanjung Morawa Kabupaten Deli Serdang dan dimulai pada bulan April sampai dengan September 2016. Penelitian ini menggunakan rancangan acak lengkap non faktorial dengan perlakuan jarak tanam dan sistem tanam, J1 (disemai dengan jarak tanam 20 x 20 cm), J2 (disemai dengan jarak tanam 25 x 25 cm), J3 (disemai dengan jarak tanam 30 x 30 cm), J4 (ditanam langsung dengan menyebar 33 benih padi/plot), J5 (ditanam langsung dengan jarak tanam 20 x 20 cm), J6 (ditanam langsung dengan jarak tanam 25 x 25 cm), J7 (ditanam langsung dengan jarak tanam 30 x 30 cm), J8 (Legowo 2:1), J9 (Legowo 4:1). Yang diulang sebanyak 3 kali. Hasil penelitian menunjukkan penerapan beberapa jarak tanam dan sistem tanam berpengaruh meningkatkan produktivitas padi sawah (Oryza sativa L.) Hasil terbaik diperoleh pada perlakuan J9 (legowo 4 : 1).

Golden snail (Pomacea canaliculata L.) able breed quickly at flood area and hold out at 6-8 weeks at dry condition. Modification of water heights and concetrations of mollucicides are be expected decrease the population of golden snail (Pomacea canaliculata L.). This research was studied at paddy field of Tanjung Mulia Village, Tanjung Morawa District from April 2016 until August 2016. This research used completely randomized design with two factors consist of water heights of paddy field (H) such as, 0 cm; 2,5 cm; 5 cm and consetrations of mollucicides (M) such as, 0 g/15L water;100 g/ 15L water; 300 g/ 15 L water. Combinations treatment are repeated at three times and there are 27 treatments. The results showed the decreasing of water heights at paddy field can decre the population of golden snail (Pomacea canaliculata L.) and dry grain weight brutto; application of mollucicides showed response about golden snail (Pomacea canaliculata L.) and many parameters of rice; combination of decrease water height in paddy field and consetration of mollucicides did not show response about golden snail (Pomacea canaliculata L.) and many parameters of rice. Key words : golden snail, height water, mollucicides

The research was conducted at rice field in Medan Tuntungan which about ± 25 metres above sea level, begun from March until June 2017 using completly randomized design with two factors, i.e: the number of seeds (1,2,3) and plant population based on modified jajar legowo planting system (conventional planting system with population of 48 clumps per plot, jajar legowo planting system with population of 60 clumps per plot, jajar legowo planting system with population of 114 clumps per plot, jajar legowo planting system with population of 154 clumps per plot, jajar legowo planting system with population of 190 clumps per plot). The results showed that 1 seed of clumps with conventional planting system with population of 48 clumps per plot significantly influence the increase of rice production (Oryza sativa L.). The interaction between number of seeds dan plant population significantly increased growth but did not significantly increase rice production (Oryza sativa L.). Keywords : jajar legowo, number of seeds, rice

Rice is the main food needs for the community in Indonesian. Fertilization is one of the activities is very important in increasing the production of rice plant. This research aims to study the influence of granting demand fertilizer plant and soil nutrient indexes against the growth of vegetative rice plant. This research was carried out in lawland district Medan Baru at the points of coordinates 3.331810 LU and 98.385300 BT from August until December 2016. The experimental design used completely randomized design with two factor. The first factor was the provision of Urea, SP36, KCL, and Dolomit. P1= 121,36 gram/plot, P2= 161,82 gram/plot, P3=202,27 gram/plot, P4= 242,73 gram/plot and the second factor was based on soil nutrient index B1= 0,8 (dose less 20), B2= 0,9 (dose less 10%) B3= 1 (100% standart nutrient index), B4= 1,1 (dose plus 10%), B5= 1,2 (dose plus 20) were repeat twice.The result of experiment showed that P2B1 =129,45 gram/plot the best combination of the application of fertilizers and soil nutrient index P4= 242, 72 gram/plot was the best fertilizer dose treatment B2=0,9 (dose less 10%) was treatment of soil nutrient index. Keywords : fertilizers, nutrient indexes, paddy
