A study was conducted during two planting seasons, namely planting season 1 (PS-1) 2017/2018 and (PS-2): 2018/2019, in Oelnasi Village, Central Kupang sub-district, Kupang District, East Nusa Tenggara, Indonesia. This study aimed to evaluate the rotation pattern of maize with legumes ground covers towards the dynamics of soil carbon and nutrients N, P, K during the two growing seasons in a dryland farming system. The experiment was designed using a randomized block design with 3 (three) treatments replicated five times. The treatments evaluated were: crop rotation patterns consisting of: without rotation (farmer practice) and rotation pattern with Phaseolus lunatus; rotation pattern with Mucuna pruriens. Legume crops planted after harvesting the food crop and allowed to grow during the dry season. Approaching the rainy season, the biomass of the legume crop is returned to the land by immersing them it together with soil cultivation. Chemical fertilizers is given as an independent variables with a dose of 150 kg/ha of Urea; 100 kg/ha of SP36 and 100 kg/ha of KCL. The results showed that the rotation pattern of Mucuna pruriens significantly increased the soil organic C content by 50.56% and legume Phaseolus lunatus by 37.64% to PS-2. The rotation pattern of the legume covers / covered crop also significantly increased the efficiency of agronomic nutrients (N, P, and K nutrients) and maize yields during the two growing seasons. On the other hand, the farmer pattern (without rotation) showed a decrease in soil carbon to PS-2 which of course affect the efficiency of nutrient absorption.

Research about land productivity and efficiency of integrated farming systems on dryland agroecosystems had been conducted in farmers owned land in Fatukanutu village with land characteristics at a slope of <15% and altitude <500 m above the sea level. This research is secondyear research, which was carried out from January to November 2018. The purposes of this study are to implement an integrated farming system in dryland and lowland agroecosystems, to assess land productivity in an integrated agricultural system model (SPT) and the efficiency of land use on cropping patterns in the SPT model in lowland and dryland agroecosystems. The results showed that the model applied in the field is a banana-based integrated farming system, which is following the local and potential components such as livestock, food crops (maize), vegetables and fodder ( lamtoro) with intercropping harvesting system (Tumpangsari and TumpangGilir). Compared to monoculture crops, land productivity in integrated farming systems in dryland banana zone in agroecosystems ismore productive. Also, cropping patterns in SPT model are beneficial because the LER value is > 1, there is efficiency in land use on banana-based SPT, with the LER value of banana-corn 1.15, banana-vegetable 1.65 and banana-maize-vegetable 2.80

Utilization of Agricultural Biochar Waste as Soil Conditioner for Improved Soil Quality and Result of Corn in Dryland. Optimization of degraded dryland use need to be increased through by materials soil conditioner ground added, such as biochar which made from agricultural waste. Organic soil conditioner has been shown effective to accelerate the recovery of degraded drylands caused by conventional farming. This study aims to determine the effectiveness of biochar as a soil conditioner on the soil quality improvement and yield of corn in dryland as well. Research was carried out at State Agricultural Polytechnic field practice which is located in Oesao, East Kupang, Kupang regency, East Nusa Tenggara province. Design of this study was split plot factorial with three replications. The first factor as the main plot is kind of biochar, with four types, namely: Bs: biochar cow dung; Bp: rice husks; Bg: pruned G. sepium; and Bj: corn stover. The second factor as sub plots are doses of biochar, with three levels, namely: D1: 3 t ha-1; D2: 6 t ha-1; and D3: 9 t ha-1. The results showed that no interaction between the type and dose of biochar on soil quality and yield of corn. Each single factor either main plots and sub plot gave a significant difference on the quality of soil and yield of corn. Corn stover biochar and pruned G. sepium better improve soil quality and yield of corn in dryland than biochar that made from cow dung and rice husk. Doses tested biochar also showed different results and significantly improve of the soil quality and yield of corn.

Matheus R, Basri M, Lewar Y. 2020. Development of mamar-based integrated agriculture model in Kupang district, east Nusa Tenggara. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).For the Timorese people, mamar has strategic meaning. Mamar is also defined as a form or pattern of integrated farming developed on a stretch of land around a spring. Mamar productivity continues to decline due to lack of management by farmers. This study aims to identify the characteristics of mamar in the Kupang district, in order to develop more productive and sustainable mamar. This study used a survey method. which is carried out through field observations including observing the physical condition of the mamar environment, identifying the constituent components of the mamar, tracking the area of the mamar and taking soil samples. The results showed that: In mamar management, indigenous peoples apply a zoning system, which is divided into a core zone, a buffer zone and a development zone, with different utilization patterns; Mamar has 3 functions, namely: ecological, economic and social functions; One of the advantages possessed by mamar is the high value of sustainability; Mamar productivity can be increased through several forms, namely rejuvenating core plants in mamar, and inducing long-aged plants with high economic value and utilizing the space under annual plant stands with bio-plants. It is necessary to re-strengthen customary institutions in each mamar area; Mamar development needs to be directed to provide a multiplayer effect for local communities.

The purpose of this study was to evaluate the effect of the treatment of organic material sources Mucuna and Crotolaria and the dose of vesicle arbuscular mycorrhizae (VAM) on the chemical quality of vertisol, nutrient uptake and maize yield in dry land. The research was carried out in the experimental field of the Kupang State Agricultural Polytechnic, in the village of Oesao, East Kupang District, Kupang Regency, East Nusa Tenggara. The study took place from May to September 2021. The study design used a factorial randomized block design. The first factortreatment was source of organic matter (B) of ground cover plant biomass, namely: B0 = no ground cover plant biomass; BM = Mucuna and its biomass are immersed; BC = Crotolaria and its biomass immersed. The second treatment was dose of VAM biofertilizer (D), namely: M0 = 0 g plant-1 (without VAM); M1 = 10 g plant-1; M2 = 20 g plant-1. The results showed that the application of organic material sources and the dose of VAM, respectively, could significantly improve the chemical properties of vertisol. The results showed that the use of organic matter and dose of VAM independently was proven to be the most effective in improving the chemical quality of vertisol. Application of organic matter Mucuna and Crotolaria at a dose of VAM 20 g plant-1 significantly increased N uptake in maize by 53.26‒54.45%, maize P uptake by 27.83% and 28.85%, and the yield of dry shelled corn by 146.92% and 146.92% compared to other treatments.
