“…Some of them are Inpari 38, with an age of 105 DAS, Inpari 39, with a period of 115 DAS and Inpari 41, with an age of 114 DAS (Ministry of Agriculture, 2022). Noviana et al (2021) reported that Inpari 39, Cakrabuana, Inpago 11, Rindang 1 and Luhur 1 have the potential to experience drought stress during the dry season on rainfed paddy fields with average productivity of 6 to 7 t ha -1 . Further, Cakrabuana has the highest grain yield around 7.15 t ha -1 when matured at 85 days after planting.…”

Rainfed paddy fields have a great potential to be developed in Indonesia, especially in Central Java. However, water irrigation management, drought stress, pest and disease infestation and low nutrients that affect paddy yield remain the constraints. Unpredictable climate pattern is also a limiting factor in the cultivation of rainfed paddy fields. This narrative review aims to identify and discuss solutions to problems that exist to increase the yield of rainfed paddy fields with several techniques that support sustainable agriculture. This review paper was prepared by collecting government data and interviews with several farmer group leaders as complementary data. Based on field conditions, farmers in rainfed paddy fields provide fertilization inputs that are not following the fertilizer recommendations. Moreover, field conditions with limited water availability have caused paddy cultivating in several locations only once a year with low yields. Water storage can help farmers meet the need for water, especially during dry and water-stress conditions. The farmers also need to pay attention to the appropriate fertilization doses and the use of additional organic matter derived from cultivation residues, which are expected to increase the availability of nutrients in the soil. The use of short-life and drought-resistant varieties can aid in overcoming the problem of crop failure in the middle phase caused by water scarcity. Finally, we identify and emphasize that rainfed paddy fields generally have a limiting factor for water and nutrients and several technologies are needed to contribute to increasing more sustainable paddy yields.

“…Mitigation management can be done by: 1) Use early maturing varieties and drought stress tolerance varieties. The use of early maturing to facing drought stress can be used to increase crop index (CI) and it will maintain high yields [158]. Drought tolerance varieties can respond and induces expression of drought stress related genes so that the plant will survive in these conditions [159].…”

The function of water for plants is crucial, including playing the roles in metabolic reactions. The aims of this article are to give information on the effects of drought stress on plant morphology, physiology, and biochemistry, as well as mitigation methods in drought stress management for plant production. Plants manage drought stress using a mechanism, namely drought escape, drought avoidance and drought tolerance. Drought escape is the ability of plants to accelerate flowering or life cycle, drought avoidance is the ability of plants to reduce water loss and increase water absorption through morphological changes in the root system, drought tolerance is the plant adaptation to drought by changes in plant physiological and biochemical processes. Physiological changes that occur include closing the stomata and decreased photosynthesis. The biochemical responses include the synthesis of solute compounds as a form of osmotic adjustment in the cell called osmotic adjustment to reduce water loss from the cell. The biochemical indicators are the increased concentrations of abscisic acid (ABA), proline, and sugar (trehalose). ABA acts as a signal to stimulate stomatal closure to reduce the transpiration rate. Proline is an indicator of plants adapting to drought stress, playing a role in the osmotic adjustment of cells to retain in the cell. Trehalose is a compatible sugar acting as an osmoprotectant, it can maintain the integrity of cell membranes (water replacement) and form hydrogen bonds (water entrapment). Plants under drought stress conditions can adapt by making morphological, physiological, and biochemical responses by osmotic adjustment. These conditions need to be managed so that appropriate strategies and technologies are needed as mitigation measures.

“…Climate change will decrease soybean production, especially due to rising temperatures in future climates, changing rainfall patterns, and unpredictable droughts/floods [8,9,10,11,6]. One of the ways for farmers to adapt to the impacts of climate change is by introducing new high-yielding, early maturing varieties, and drought-tolerant varieties [12]. One of the soybean varieties recommended for farmers' adaptation to climate change is the Biosoy soybean variety.…”

The climate change impact is cropping patterns change, including unpredictable droughts and floods. These conditions require soybean farmers to adapt, one of them is adopting early maturing soybean varieties. This research aims to identify the advantages of early-maturity soybean varieties, financial feasibility, and technical Efficiency. This study collected data from 40 soybean farmers in the Grobogan Regency. Soybean farming data used in planting season III (May-August) 2021. Biosoy varieties are early maturing, compared to the Anjasmoro varieties as existing soybeans. The financial feasibility of early-maturing soybeans is analyzed by the Marginal Benefit Cost Ratio (MBCR), while technical Efficiency is by stochastic frontier. The research showed that a) advantages of Biosoy early-maturing soybeans include higher production, larger seeds, and reduced risk of crop failure due to drought; b) Biosoy varieties are feasible to develop with an MBCR level of 3.19, and c) an average technical efficiency is 0.92. Biosoy varieties demonstrated better advantages than Anjasmoro varieties. The government, as a policy maker, is expected to be able to encourage farmers to adopt Biosoy varieties and optimize production inputs to make them more efficient so that farmers can adapt to climate change adaption.
