Nutrient availability affected plant growth and yield. This study aimed to examine the effect of interval application and fertigation frequency toward plant growth and yield, and further determined the most proper fertigation interval and frequency that support the highest plant growth and yield. Experiment was arranged in Split plot randomized Completely Block Design. The main plots were interval of nutrient application, i.e., 3 days interval, 6 days interval, 9 days interval. The sub plots were the frequency of nutrient application, i.e., once/day, 2 times/day, 3 times/day. The plot size for each treatment was 2.5 m×1.3 m and plant spacing was 15 cm×20 cm. Space between beds was 1 m. Red onions (Bima variety) were planting in a raised bed covered with silver black polythene mulch. Before planting, 5 ton/ha manure and 1 ton/ha lime were mix with the soil. Fipronil 1.5% was applied with dose 8 kg/ha to control grubs. Nutrient was mixture between liquid organic fertilizer (7.5 mL/L), rabbit urin (5mL/L) and AB Mix (7.5 mL/L A+7.5 mL B). The nutrient was dispensed 150 mL/plant according to treatment using fertigation system operated remotely using Internet of Things. The nutrient was given from 14 DAP (Days After Planting) until 68 DAP. Irrigation water was dispensed 150 mL daily in the same way. The interval of fertigation significantly affected the growth of red onion (plant height, number of leaves and number of yield). Three days interval of nutrient supply resulted in the tallest plant, highest number of plant leaves, and highest number of bulbs. However, the frequency of nutrient supply daily significantly affected the yield of red onion. The application of nutrient three times/day provided the highest yield (economical dry weight). Further research to examine the effect of fertigation of red onion quality is required.

The experiments was conducted at Kasang village, district of Batang Anai, Padang Pariaman regency during June until December 2013. The objectives of this experiment was to increased lowland rice production through specific location of nutrient management (SLNM) on low potential productivity of lowland. Four packages of fertilization such as Package A, B, C and D were arranged in Randomized Completely Block Design (RCBD) with 6 replications. Result of this experiment showed that; (1) SLNM treatments were significantly affected plant growth such as tiller number and plant high. Saveral of yield components also significantly affected by SLNM treatments packages such as panicles number, number of seeds per panicle, and percentage of filled grains. SLNM package A, B, and C significantly increased grain yields such as 24.9%,  34.2%, and 29.5% respectively compred to farmer package (Package D). The low grain yield with Famer package caused insufficient nutrient supplied for plant growth and yield is due to low fertilizer application and inaccurate nutrient management. The experiment suggested that the best application of inorganic fertilizer should be followed or combined with organic fertilizer such as animal manure or compost and  the application of thus material should be in mature condition. Key Words:  rice, specific location, fertilizer

Inoculating groundnut and cowpea with highly effective and competitive rhizobial strain improves nodulation. A field experiment was carried out at the experimental field of the Faculty of Agriculture, University for Development Studies, Nyankpala, to evaluate the growth and yield responses of cowpea and groundnut to five rhizobial inoculant strains in the Guinea Savanna zone. The experiment was laid out in a randomized complete block design (RCBD) with eight (8) treatments replicated four (4) times. The treatments included five rhizobial inoculant strains (NC 92, KNUST 1002, KNUST 1003, KNUST 1006, and BR 3267), two N fertilizer levels (20 kg·N/ha and 40 kg·N/ha), and a control. The results showed that rhizobial inoculation and N fertilizer application increased nodulation, biomass yield, pod number, pod weight, hundred seed weight, nodule dry weight, and pod yield of groundnut compared with the control. Rhizobial inoculation averagely increased the nodulation and yield by 63 and 67%, respectively, compared with the control. Mineral N fertilizer (20 kg N/ha) on average increased the nodulation and yield by 24 and 25%, respectively, compared with the control plots. It can be recommended from this study that, in the absence of highly competitive rhizobial strains such as KNUST 1006 and NC 92 as biofertilizers for increasing the nodulation and yield of cowpea and groundnut, 20 kg·N/ha can be used for the purpose. Further research is recommended using these rhizobial strains in combination with lower rates of N fertilizers (<20 kg·ha−1).
