Nitrogen was a key component for increasing yield and quality of vegetables like shallots. The growth and development of plants were influenced by nitrogen form. Common plants preferred nitrate for growth, but the enormity preference varies within plant species and other environmental factors. The purpose of this experiment was to study the effect of ammonium:nitrate ratio in sandy soil to growth and yield of shallot (Allium cepa L. Aggregatum group). The experiment had been conducted in August-October 2015 in the sandy land on Samas Beach, Bantul, Yogyakarta, Indonesia. The research was arranged in a Split-Plot design. The main plot was the source of nitrogen (NH4+; NO3-; NH4+: NO3- 1:1; NH4+: NO3- 1:2; and NH4+: NO3- 2:1) and the subplot was cultivars (Crok Kuning, Tiron, and Bima Brebes). Each subplot covered an area of 2.5 m² (2.5 m x 1 m) with three blocks as replications. Shallot bulbs were planted in sixth-row, spacing 20 cm between rows and 15 cm within rows. The dose was applied according to the recommendation of BPTP (urea 200 kg ha-1, ZA 250 kg ha-1, SP-36 150 kg ha-1, and KCl 150 kg ha-1) 144.5 kg N ha-1. Ammonium:nitrate ratio influenced shallot growth in sandy soil through number of leaves at maximum vegetative phase and its leaf area. The NH4+: NO3- 1:2 ratio gave the best result in dry weight of leaves following bulb dry weight than other ratio. Nevertheless, ammonium:nitrate ratio had no significant influence on bulb dry weight (ton ha-1).

Existing knowledge about biochar is derived from trials where biochar incorporation into the soil is done by hands, a practice too tedious to scale-up to commercial levels. To enhance scalability, biochar incorporation needs to be integrated into conventional mechanised tillage systems. This study aimed at assessing the effects of incorporating biochar by power tiller and ox-plough on soil water retention, maize growth and yield. A 2 x 3 factorial experiment was conducted in a split-plot design with biochar incorporating method as a main plot factor and biochar level as subplot factor, on ferralsols of central Uganda. Incorporation methods were by power tiller and ox-plough with hand mixing in planting basins as a control, while levels of biochar were 0 and 10 t ha-1 application rates. Data was analysed using two-way ANOVAs in Minitab for significant differences among incorporation methods. Results showed that incorporating biochar by power tiller significantly increased water retention effect of biochar by 27.5% (p < 0.05), while no significant effect was observed (p ≥ 0.05) when incorporated by ox-plough, compared to hand mixing. No significant difference on growth and yield was observed (p ≥ 0.05) as a result of incorporating biochar by power tiller and ox-plough instead of hands in planting basins. These findings suggest that biochar incorporation can be scaled-up, to commercial levels, through the use of power tiller and ox-plough, without negative effects on biochar performance. It is recommended that promotion of biochar technology encompasses the use of power tillers and ox-ploughs to enhance scalability.

Effects of crop arrangement and cutting on the silages quality of two varieties of maize (Zea mays L.)ABSTRACT. The objective of this experiment was to study the interaction effect of varieties, spacing and cutting on the quality of silage as foodstuff. The experiment had been conducted from January to April, 2007 at the experimental Garden of Faculty of Agriculture, University of Haluoleo. This experiment was arranged in Split-Split plot design with three factors. The first factor was variety as main plot, consisting of BISI-2 variety and local variety; the second factor was space arrangement as sub plot, consisting of 60 cm x 40 cm (J1), 75 cm x 40 cm (J2), 90 cm x 40 cm (J3), the third factor was cutting period as sub plot, consisting of no cutting (Po), cutting on 40 days (P1), and cutting on 55 days (P2). So that there were 2 x 3 x 3 x 3 = 54 experimental units. Analysis of variance was applied to know the effect of treatment. If so, least significant difference (LSD) 0.05 (95 %) confidence level was used. Variables observed was plant growth determining silages quality, consisting of quality of crude protein, crude fiber, crude fat, and water. Results of research revealed that interaction affect of spacing and cutting periods on 40 days of BISI-2 variety gave the best yield of plant growth for plant height. While the local variety tended to adverse effect of cutting. However, the quality of silages of two varieties tended to be similar. Every crop spacing had a positive effect of cutting on 40 days. The best quality of silages of two varieties was resulted from the interaction between spacing 75 cm x 40 cm and cutting of 40 days.

Melon are one of the most popular fruit commodities, but, despite the demand, its production in Indonesia has declined. One measure that can be used to optimize the quality of melon fruit is to trim off the leaf buds and arrange the position of fruiting on the stem, and this study, using the golden melon cultivar ‘Apollo,’ aimed to identify the effects of leaf bud trimming and fruit position arrangement in improving the quantity and quality of the fruit harvest. The experiment was conducted from March to May 2018 in the greenhouse of Food Crop and Horticulture Agribusiness Development (UPT Pengembangan Agribisnis Tanaman Pangan dan Hortikultura), in Lebo, Sidoarjo, Indonesia. It was based on a split-plot design, with leaf bud trimming as the main factor, consisting of two groups (trimming or not trimming), and fruit positions as the secondary factor, consisting of four stages, all repeated at four different time intervals. A correlation was found between leaf bud trimming and fruit position arrangement toward the number of leaves. However, the treatments did not affect the growth and yield of the plants, but did have a significant effect on fruit weight, sweetness, and volume. It was concluded that trimming off the leaf buds and arranging the fruiting position on golden melon plants can increase the quality of fruits, with the treatment involving trimming combined with arranging fruiting on the twelfth–thirteenth segment showing the best results.
