Field trial was conducted during the 2017 dry season from March to June at Bayero University, Kano and Birji village both in Sudan savannah to determine the effect of compost rates and irrigation intervals on the growth and yield of onion (Allium cepa L.) The treatments were conducted in five rates of compost (0 t ha-1, 5 t ha-1, 10 t ha-1,15 t ha -1 and 20 t ha-1) and three irrigation intervals (5, 10 and 15 days). The treatments were laid out in a split plot design and replicated three times. Irrigation intervals were assigned to the main plot while compost rates were assigned to the sub plot. The gross plot size was 1.5 m x 2.0 m (3.0 m2) consisting of 10 rows of 2 m length. Data on growth and yield parameters were collected, weighed and subjected to analysis of variance (ANOVA). Treatment means were separated using Student-Newman-Keuls Test. The result ssize was 1.5 m x 2.0 m (3.0 m2) consisting of 10 rows of 2 m length. Data on growth and yield parameters were collected, weighed and subjected to analysis of variance (ANOVA). Treatment means were separated using Student-Newman-Keuls Test. The result showed that compost rates and irrigation intervals had significant effect on cropgrowth rate, relative growth rate, net assimilation rate and cured bulb yield. Application of 10 t ha-1 of compost had the heaviest cured bulb yield. Interactions between compost rates and irrigation intervals were significant on all the measured parameters as well as the cured bulb yield of onion at both locations. The optimum rate of compost was 15 t ha1 at both locations, while that of irrigation intervals were 10 and 5 days for BUK and Birji village, respectively. Therefore, these levels were recommended to be used by farmers of the study areas.

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.

Shallot (Allium cepa L. Aggregatum group) is one of the most widely utilized vegetables by Indonesian people. Some technologies have been adapted to improved shallot productivity. One of those are the application of beneficial microorganisms. We applied mycorrhizal fungi, Trichoderma sp., and Bacillus thuringiensis as well as the combination among these microorganisms were applied in Shallots cultivation and were investigated to improve the growth and development of shallot. A field experiment was arranged in a Randomized Complete Block Design with two treatment factors. The first factor consisted of two shallot cultivars, namely Biru Lancor and Crok Kuning; whilst the second factor consisted of six beneficial microorganism treatments, i.e. control, mycorrhizae, Trichoderma sp., Bacillus thuringiensis, the combination of mycorrhizae and Trichoderma sp., and the combination of those three microorganisms. The observation was conducted on infection percentage of mycorrhizae, total population of Trichoderma sp., leaf area, leaf area index, net assimilation rate, crop growth rate, harvest index, and plant yield. The data obtained were subjected to analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at 5% significance level. The results showed the leaf area of shallot was improved as affected by the application of mycorrhizal fungi. The effectiveness and implication of mycorrhizal fungi on shallot growth would decrease if the application of was combined with other microorganisms. However, the application of beneficial microorganisms had not been able to increase component yield and yield of Biru Lancor and Crok Kuning, indicated by bulb weight, number of bulb, bulb diameter, number of bulb per cluster, and bulb yield per hectare.
