Phosphorous Concentration

The phosphorus element plays an essential role in plant growth both at the vegetative and generative phases, so its concentration modification in the nutrient solution is necessary to stimulate vegetative growth and crop yield. The research aimed to know the influence of different phosphorus concentrations on growth and yield of cherry tomato using a hydroponic drip irrigation system, conducted from February to June 2017 at Green House Research Station of  Universitas Padjajaran Jatinangor using Completely Randomized Design with five treatments and five replications. The treatments were: phosphorous concentration of 100 ppm (P/N ratio 0.4), 125 ppm (P/N ratio 0.5), 150 ppm (P/N ratio 0.6), 175 ppm (P/N ratio 0.7), and 200 ppm (P/N ratio 0.8). The results showed that the increasing concentration of phosphorus improved crops height at the end of the vegetative phase, increased the number of flowers from the beginning to the end of the generative period, was able to prevent the flower fall, enhanced harvest index and weight of tomato fruit significantly at harvest time. Application of 200 ppm phosphorus concentration can increase growth and yield of cherry tomato. Unsur fosfor berperan penting dalam pertumbuhan tanaman pada fase vegetatif maupun fase generatif. Konsentrasi unsur P pada nutrisi tanaman sangat penting untuk merangsang pertumbuhan vegetatif dan hasil panen. Penelitian ini bertujuan untuk mengetahui pengaruh ragam kosentrasi unsur posfor terhadap pertumbuhan dan hasil tanaman tomat cherry pada sistem hidroponik irigasi tetes. Penelitian telah dilaksanakan pada bulan Februari sampai Juni 2017 di Green House Universitas Padjadjaran Jatinangor menggunakan rancangan acak lengkap terdiri dari lima perlakuan dan lima ulangan. Perlakuan konsentrasi posfor, yaitu 100 ppm (rasio P/N 0,4), 125 ppm (rasio P/N 0,5), 150 ppm (rasio P/N 0,6); 175 ppm (rasio P/N 0,7), dan 200 ppm (rasio P/N 0,8). Hasil penelitian menunjukkan bahwa peningkatan konsentrasi posfor meningkatkan tinggi tanaman pada akhir fase vegetatif, meningkatkan jumlah bunga dari awal sampai akhir fase generatif, mengurangi jumlah bunga gugur, meningkatkan indeks panen dan berat buah. Aplikasi konsentrasi posfor 200 ppm dapat meningkatkan pertumbuhan dan hasil tanaman tomat cherry.

Abstract: The objective of this work was to evaluate the growth and yield of teak (Tectona grandis) stands at different spacing and in different soil classes. Twelve spacing were evaluated in an Inceptisol and Oxisol, in plots with an area of 1,505 or 1,548 m2, arranged in a completely randomized design with nine replicates. The teak trees were measured at 26, 42, 50, and 78 months of age. Total tree height was less affected by spacing. Mean square diameter was greater in wider spacing, whereas basal area and total volume with bark were greater in closer spacing. An increase in volume with bark per tree was observed with the increase of useful area per plant. For teak trees, growth stagnation happens earlier, the growth rate is higher in closer spacing, and the plants grow more in the Inceptisol than in the Oxisol.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.

Field experiment was conducted at National Horticultural Research Institute (NIHORT), Mbato Sub-station, Okigwe, Imo State, South-eastern Nigeria in the 2012 and 2013 cropping seasons to establish the most appropriate time to introduce component crops in cocoyam/cowpea mixture. Five different planting schemes (two and four weeks before, two and four weeks after and same day) and two cowpea genotypes (climbing Akidienu and erect IT97K-499-35) were used. The component crops were grown in monocultures to assess the productivity of the systems. The experimental design used was a completely randomized design with three replicates. Growth and yield of cocoyam and the cowpea genotypes increased significantly (P<0.05) when either of the component crops was planted earlier than the other. Intercropping reduced significantly (P<0.05) cocoyam yield by 0.7 − 74% in IT97K-499-35 and 22 − 80% in Akidienu. Sowing the cowpea genotypes the same day or before cocoyam resulted in over-yielding of cowpea, whereas sowing Akidienu and IT97K-499-35 after cocoyam caused pod yield reductions of 64% − 73% and 32% − 59% on average, respectively. Cocoyam planted two weeks before IT97K-499-35 produced more satisfactory yields of the intercrops than the other planting schedules with LER, LEC and ATER of 2.15, 1.03 and 1.57, respectively.
