“…Di Nusa Tenggra Timur, kacang hijau merupakan komoditas strategis karena sifat agronomisnya yang relatif tahan terhadap kekeringan dan umur panen yang pendek. Ketahanan terhadap kekeringan inilah yang menjadikan komoditas kacang hijau sering ditanam setelah padi sebagai tanaman palawija atau sebagai tanaman sela (Asadi et al, 2017;Azka, 2021;Purwanto et al, 2019). Selain itu, kacang hijau juga merupakan komoditas kacang-kacangan yang mempunyai arti penting bagi masyarakat, baik dilihat dari nilai ekonominya yang tinggi maupun dari kandungan gizinya.…”

“…Selanjutnya, dalam usahatani kacang hijau ini varietas benih yang banyak digunakan adalah Vima 2 dan Vima 3. Dilaporkan varietas Vima ini tahan terhadap kekeringan, khususnya telah dibuktikan oleh Purwanto et al, (2019) pada varietas Vima 3. Penggunaan benih oleh petani di lokasi penelitian berkisar antara 5 kg sampai dengan 20 kg untuk setiap petani, sedangkan kebutuhan benih setiap hektar kurang lebih 20 kg.…”

The cause of the low productivity of mung beans is partly due to the inefficient use of production factors, which will theoretically affect the profit level of farming. This study specifically aims to analyze the allocation of the use of production inputs and to analyze the profit function of mung bean farming. Data collection used a survey method by interviewing 52 farmers in Central Malaka District, Malaka District, East Nusa Tenggara. Data analysis used a quantitative descriptive method, through the analysis of farm costs, and analysis of the Cobb-Douglass Unit Output Price profit function. The results showed that mung bean farming was profitable with a profit rate of around 7.66 million rupiah per hectare. The allocation of farming inputs that significantly affect production are land area, seeds, and pesticides, with coefficient values of 0.96, 0.56 and -0.49, respectively. Meanwhile, variable inputs that significantly affect profits are fertilizer prices, pesticide prices, and labor costs, with coefficient values of -0.43, 0.43, and -0.75, respectively. These results inform several aspects: (a) increasing the area of land and seeds increases production, conversely increasing the use of pesticides can reduce production and therefore it is necessary to adjust the correct dosage, (b) the use of fertilizers is not significant to production caused by the application dose is too low, ( c) the use of labor is not significant to production and its addition reduces profits, so it needs to be more efficient in its use by prioritizing the quality of the workforce.

“…Budidaya tanaman dengan sistem tanpa olah tanah (TOT) akan memiliki beberapa keuntungan untuk tanaman. Selain mengurangi evapotranspirasi, erosi, pemadatan tanah, memperkecil erosi dan pencucian unsur hara serta melestarikan kesuburan tanah, namun sistem TOT kurang optimal untuk mengendalikan gulma (Purwanto, 2010). Kelebihan lain dari cara penanaman TOT ialah mempertimbangkan aspek kelestarian sumber daya tanah dan air disamping aspek produksi dan pendapatan petani.…”

One of the factors that decrease the production of the soybean crop is the low level of soil fertility. Soil fertility can be improved with the use of mulch combined with proper tillage. This Research is needed to determine the dose and the right soil processing combined with optimal doses of straw mulch to improve the growth and yield of soybean.This research conducted wit Split Plot Design with three replication, with soil tillage as main plot and rice straw mulch as sub plot. Soil tillage arranged with 3 level, O1: maximum soil tillage O2: minimum soil tillage and O3: without soil tillage. Rice straw mulch arranged with 4 level, M0: without rice straw mulch (control), M1: rice straw mulch 2 ton/ha, M2: rice straw mulch 4 ton/ha and M3: rice straw mulch 6 ton/ha. The results showed there were no significant interactions and influences between pemulsaaan treatment combined with tillage on the growth and yield of soybean.

“…Riduan et al (2005) reported that peanut cultivars resistant to drought stress are able to rapidly accumulate proline in leaves (from 177% to 242%) compared to other intolerant cultivars. Whereas a study on mung beans showed that drought stress that reaches up to 50% of field capacity has shown a decrease in the leaf area and plant dry weight without any effect on proline content (Purwanto et al 2019).…”

Abstract. Syafriani E, Susilo KR, Sayekti RS, Widyawan MH, Khoirunnisa NS, Rahmadhani M. 2022. Comparative study of morphophysiological responses among cowpea and long beans plants under drought stress condition. Biodiversitas 23: 5507-5518. Long bean plants are generally more susceptible to drought stress than cowpea plants. One of the promising solutions is through plant breeding to produce genetically modified long bean plants resistant to drought stress by crossing with cowpeas. Parental selection is the initial stage of the plant breeding program. This stage was performed by selecting parental varieties based on the desired superior characteristics, including morphological and physiological characteristics, as well as, yield production. Unfortunately, the comparison between long bean plants and cowpea plants is not well-studied. Therefore, the aim of this study was to analyze the morphophysiological similarities and differences between long beans and cowpeas to withstand drought stress. A two-factorial randomized block design was used in this study and consisted of 2 factors (plant varieties and type of drought stress). The plant varieties used in this study are 7 long bean plants and 7 cowpea plants. While the level of drought stress were: T0 (watering every day), T1 (every 5 days), and T2 (every 10 days). The observational data from morphophysiological characters indicated that long bean plants were more tolerant to drought stress than cowpea plants. Interestingly, one of the cowpea varieties (C2) had the highest proline contents (20.27 µmol/gram of leaves sample) compared to other varieties. Hence, the C2 variety can be considered a candidate for further studies. Meanwhile, all the tested 7 varieties of long bean plants showed varying adaptability, possibly due to the genetic diversity of each variety against drought stress.
