Dari hasil percobaan disimpulkan bahwa pemberian 200 gram inokulan Trichoderma sp dan 75 ml L-1 POC yang diberikan setiap 2 minggu mampu meningkatkan pertumbuhan dan hasil tertinggi berat buah segar mencapai 1,33 kg/buah Experiment "The Effect of Liquid Organic Fertilizer (LOF) and Trichoderma sp Against Growth and Melon Yield (Cucumis melo L) has been conducted in Air Pacah Koto Tangah Subdistrict in Padang City. The purpose of this research is to know the effect of liquid organic fertilizer and Trichoderma sp on growth and yield of Melon (Cucumis melo L). This study used a complete randomized design of 2 factors (Trichoderma sp and POC). Trichoderma sp consists of 2 levels of 0 g L-1 and 200 g L-1 per plant, whereas POC administration consists of 4 levels ie 0 ml L-1, 25 ml L-1, 50 ml L-1 and 75 ml L-1 with 3 replications and each unit of experiment 2 polybag so obtained 48 polybags. The experimental resulted that giving 200 grams of Trichoderma sp inoculum and 75 ml L-1 POC was given every 2 weeks can increase the growth and yield of melon. The highest yield of fresh fruit 1.33 kg/fruit.

The objective of this study was to assess the impacts of nitrogen on the physiological characteristics of the source–sink system of upper fruiting branches under various amounts of nitrogen fertilization. A two-year field experiment was conducted with a Bt cotton cultivar in the Yellow River Basin of China. The growth and yield of cotton of the upper fruiting branches were compared under four nitrogen levels: Control (N0, 0 kg ha−1), low nitrogen (N1, 120 kg ha−1), moderate nitrogen (N2, 240 kg ha−1), and high nitrogen (N3, 480 kg ha−1). The results indicated that in the subtending leaves in upper fruiting branches, chlorophyll content, protein content, and peroxidase (POD) activity dramatically increased with nitrogen application, reaching the highest under the moderate nitrogen treatment. The physiological characters in the seeds had the same trends as in the subtending leaves. Furthermore, the moderate nitrogen rate (240 kg ha−1) had a favorable yield and quality. Our results supported that a moderate nitrogen rate (240 kg ha−1) could coordinate the source–sink growth of cotton in the late stage, enhance the yield and fiber quality, and decrease the cost of fertilizer in the Yellow River Basin of China and other similar ecological areas.

This study aims to determine the effect of trimming with a wide variety of growing media hydroponic system fertigation on growth and yield of melon. Research will be conducted in the green house (House of plastic) UMSIDA Agriculture Faculty, Campus 2, Gelam, Candi, Sidoarjo, research time between the months of March to June 2016 using analysis of variance and continued test HSD 5%. The variables measured were plant height, leaf number, level of sweetness of fruit, fruit weight, high-fruit, thickness of the flesh of the fruit, conclusion from this research is going on the effect of trimming and a wide variety of growing media hydroponic system fertigation in treatment PM5 (trimming down, kokopit). There was also a real influence on the treatment PM6 (without pruning, kokopit) .In observation of plant height, leaf number, fruit weight, and high fruit. And also happens to influence a wide range of growing media on growth and yield of melon on hydroponics fertigation system, the PM6 treatment (without pruning, kokopit) had the highest rates in the observation of plant height, weight of the fruit, and the number of leaves.

ABSTRACT The production of horticultural crops in no-tillage and in rotation with cover crops reduces the dependency in nitrogen fertilizer, due to increased soil organic matter and by biological fixation performed by legumes. Thus, the aim of this work was to study rates of nitrogen fertilization and cover crops in the agronomic performance of tomato and broccoli grown under no-tillage. The experiment was conducted in a split plot design with four replications. Treatments consisted of cover crops, sunn hemp and millet, and four rates of nitrogen fertilization (0, 50, 100 and 200 kg/ha of nitrogen), for both the tomato and broccoli crops. All soil management was performed in no-tillage. For tomato crops we evaluated the plant growth, the nitrate concentration of sprouts and fruits and yield of commercial and non commercial fruits. For broccoli we evaluated plant growth and yield. There was an interaction effect between cover crop and nitrogen rates to tomato growth measured at 100 days after transplanting, for plant height, number of fruit bunches, dry mass of leaves and diameter of the stalk. The tomato commercial fruit number and yield showed maximum values with 137 and 134 kg/ha of N respectively, on the sunn hemp straw. The nitrate concentration of the tomato sprouts was linearly increasing with the increase of nitrogen rates, when grown on the millet straw. For broccoli production, the maximum fresh mass of commercial inflorescence was with 96 kg/ha of N, when grown on the millet straw.
