Abstract

Lettuce and Moringa are recently popular vegetable crops because their demand improves significantly, and their development lead to dry land because its potencial in Indonesia is still high.  The use of dry land should be followed by applying inter cropping technique in order to make plant micro climate becomes more favourable. In addition, low soil fertility and intensive ussage of inorganic fertilizers makes the application of organic fertilizers imperative. The objective of the research is to investigate the type of organic fertilizer giving high yield of lettuce and moringa cultivated using inter cropping technique in dry land. The results showed that the organic fertilizers applied improved the plant growth and yield, and also improved the land equivalent ratio (LER).  The highest LER was showed by apllication of Organox, followed by  Bio Extrim and Biota Plus, and the lowest one showed by without organic fertilizer application.

Abstract

The use of high doses of chemical fertilizers in the production of chili (Capsicum annuum L.) has an adverse impact on the environment, especially in dryland. This study aimed to examine the role of cow manure (PKS), goat manure (PKK), chicken manure (PKA), or a combination of two manures in reducing 25% of the requirement for chemical fertilizer on chili plants. One experiment was carried out in the dryland of Gumantar Village, North Lombok Regency, from May to October 2021. Phonska NPK (15-15-15) chemical fertilizer (PK) at a 1,200 kg/ha dose was used as a control. The treatments tested were 75% PK+PKS, 75% PK+PKK, 75% PK+PKA, 75% PK+PKS+PKK, 75% PK+PKS+PKA and 75% PK+PKK+PKA. The dose of manure used in each treatment was 20 tons/ha. All treatments were repeated three times and arranged in a randomized block design. The results showed that the treatment of manure, especially goat manure and chicken manure, increased the available phosphate (P) in the soil. The growth and yield of chili plants were not significantly different in all treatments, which means that manure could replace the role of 25% of the chemical fertilizer used. These results indicate that manure in the long term can reduce the need for chemical fertilizers to produce chili in dryland. Key words: chili; dryland; manure; chemical fertilizer; nutrition

Abstract

Drylands with limited resource support need to increase their productivity. One indicator of land productivity is the land equivalence ratio (LER). This research aimed to study the growth and yield of red chili due to the effect of varieties and peanut planting times in intercropping systems to increase dryland productivity. One experiment was conducted in Amor-amor Hamlet, Gumantar Village, Kayangan Sub-district, North Lombok Regency, from March to August 2023. The red chili varieties tested were Baja MC (hybrid) and Landung (non-hybrid). Meanwhile, peanut (Hypoma 2 variety) planting time was at the same time, one week after planting (WAP) of chili and 3 WAP. The treatments were arranged factorially using a Randomized Block Design with three replications. All component crops had monoculture treatments to calculate LER. The results showed no interaction between variety and planting time on all parameters observed. Variety had no significant effect on growth and LER but significantly affected the yield of chili. The Landung variety produced higher yields than the Baja MC variety. Planting time treatment had no significant effect on growth and LER but significantly affected the yield of chili. The planting time of peanut that produced the highest yield was 3 WAP. The intercropping of chili with peanuts at all planting times increased dryland productivity with LER values greater than 1.0
