Effects of mulch on growth and yield of garlic bulbils at various fertilizing doses

Abstract

Climate change hurts garlic cultivation. Appropriate technology needs to be created to get good quality tubers, one of them using bulbils. Bulbils are tubers formed from other parts of a plant. In garlic, bulbil grows at the stem, with very small embryo size hence it is necessary to control the environmental conditions in the nurseries. The study aimed to examine the garlic cultivation model using tubers with mulch treatment and a combination of fertilization. Sealing and mulching were conducted to avoid direct solar heat and to control the soil microclimate, respectively. The study used a split-plot design consisting of main plots with mulching and without mulching. The sub-plots were by applying the combination of organic and inorganic fertilizers at several levels, namely: Farmer Recommendation/P1 (50% Organic + 100% Inorganic), P2 (75% Organic + 25% Inorganic), P3 (50% Organic + 50% Inorganic), P4 (25% Organic + 75% Inorganic) and P5 (100% Organic). The results showed there are interactions between mulching and a combination of fertilizers on plant height and root length. Mulch application can stabilize soil temperature and provide better results on growth and yield, but the combination treatment of fertilization has no significant effects on growth variables and yields.

Morphology, Structure and Potential of Bulbils Yield as a Planting Material of Onion in Tropical Region

“…Soil temperature affects bulb formation and bulb size [33]. Several studies have shown the effect of using plastic mulch in increasing the yield of onion bulbs [34]- [37]. Based on research results [38] that the growth of bulbils in lily plants is significantly influenced by temperature.…”

Introduction of Garlic Cultivation Technology Packages in West Java, Indonesia

“…This was presumably because the land was classified as fertile with neutral soil pH, low CN ratio, high P and K content and the use of bio protector in introduction-2 treatments which could also functioned as organic fertilizers. Study from [16] also showed insignificant effect of the use of mulching on garlic productivity, which plastic mulch and without mulch resulted in the same weight of garlic bulbs, namely 16.44 g and 16.47 g.…”

Yield Potential of Shallots Bulbil Planting Materials with Liquid Organic Fertilizer Treatment out of Season

“…The problem in tuber research is that it is vulnerable to the environment, such as soil, temperature and rainfall [10]. Climate and soil conditions such as rainfall, humidity, soil air and temperature can affect plant growth and the risk of shallot farming [11].…”
