Upland rice-based cropping pattern is a form of multiple cropping including intercropping, sequential planting, and relay planting where upland rice as a base crop can be preceded and/or rotated with other food crops as a secondary crop. The research was aimed to provide recommendations for upland rice-based cropping pattern technology in dryland agroecosystems in Maluku that would be able to increase land productivity > 1.00 (MCI = Multiple Cropping Index > 100%) compared to existing cropping patterns. The study used a Randomized Block Design (RCBD) with four treatments and repeated five times (farmers as replications). Four treatments for upland rice-based planting pattern technology assemblies, namely: 1) Pattern-A (Farmer A Pattern); 2) Pattern-B (Farmer B Planting Pattern B); 3) Pattern C (Farmer Improvement Cropping Pattern); and 4) Pattern D (Introduced Plant Pattern). The results showed that upland rice was planted double (multiple cropping) through intercropping and/or sequential cropping, namely Improved Cropping Patterns (Pattern C = Upland Rice + Corn - Peanuts) and Introducing Cropping Patterns (Pattern D = Upland Rice + Corn/Cassava - Green Beans - Peanuts) can increase land productivity with a double-cropping index 1.35 - 1.80 (IPG = 135% - 180%) compared to upland rice grown in monoculture (Farming Patterns). Multiple cropping (Upland Rice + Corn/Cassava - Green Beans - Peanuts) can be recommended as Upland Rice-Based Planting Technology Package on dry land in Maluku, because it can increase land productivity> 1.00 with an MCI (Multiple Cropping Index) of 180%.

Temulawak is rarely cultivated with any intensity because it has a long harvest time and requires wide spacing. One of the solutions for temulawak cultivation is through applying intercropping systems with corn. The current research aimed to determine the most advantageous intercropping planting pattern of temulawak and corn. The experiment adhered to a randomized block design with six treatments and four replications. The treatments were: T1 = strip cropping; T2 = row cropping; T3 = strip-relay temulawakcorn; T4 = row-relay temulawak-corn; T5 = strip-relay corn-temulawak; and T6 = rowrelay corn-temulawak. The results showed that different cropping patterns of an intercropping system of temulawak and corn affected the growth and yield of both crops. The most suitable polyculture cropping pattern, based on land equivalence ratios (LER) values and R/C ratios, was strip cropping that produced rhizhomes of temulawak of up to 2.68 ton ha-1 and of corn of up to 5.24 ton ha-1. The LER value was 1.22 and the revenue/cost (R/C) ratio was as much as 1.43 with a net profit of as much as IDR 9,509,000.

Field experiments were conducted to assess the effect of time of introduction of maize and cropping pattern on two varieties of soybean in a soybean/maize intercrop in 2007 and 2008 seasons at the University of Agriculture Makurdi. Three periods of introduction of maize were evaluated: (i) planting at the same time with soybean;(ii) introduction of maize two weeks after planting soybean and (iii) introduction of maize four weeks after planting soybean. There were five cropping patterns viz: (i) soybean variety Samsoy-2 planted sole (ii) soybean variety TGX 1448-2E planted sole (iii) maize variety DMR-ESR-Y planted sole (iv) Samsoy -2 intercrop with maize and (v) TGX1448-2E intercrop with maize. The experiment was a split plot laid on complete randomized block design replicated three times. Results obtained revealed that there was no significant effect of time of introduction of maize on any soybean parameter observed. Yield and yield components of soybean indicated significant effect of cropping pattern (P<0.01) with number of pods per plant and grain yield. Grain yield and number of pods per plant decreased in intercrop with soybean variety Samsoy-2 having the highest number of pods per plant and grain yield. The result on maize indicated that maize planted sole was significantly (P<0.01) taller than intercropped maize, there was significant (P<0.01) effect of time of introduction of maize and cropping pattern on maize plant height, ear length, ear diameter, survival and barrenness percentage and grain yield. The Land Equivalent ratio (LER) values indicated that higher yield advantages were obtained from maize introduced two weeks after planting soybean and maize intercropped with soybean variety Samsoy-2 (1.35) than with soybean variety TGX1448-2E (1.12).

Abstract An efforts to increase soybean crop productivity are highly related to of nutrients availability and crops management. This research was conducted to investigate the plant tolerance index (TI) and the mycorrhizae role to increase the availability of nutrients P and soybean productivity in a dry land. Factorial randomized block design that consists of mycorrhizal factors (0, 5, 10 and 15 g of inoculant per plant) and soybean cultivars (Anjasmoro, Dering 1 and Grobogan) and the repeated three times. The results showed that mycorrhizal inoculation with a dose of 10 g mycorrhizae per plant was able to increase the root length, root volume, dry weights, grain number and the weight of 100 grains. The highest number of grains was obtained by_ the Dering 1 cultivar. In addition the higher of 100 grains weigh was resulted by the Grobogan and anjasmoro cultivar. The cultivar adaptability was increased_ by mycorrhizal inoculation on marginal soils Further more mycorrhizal inoculation gave a nonsignificant effect of tolerance index and the highest TI (1,97) was obtained _by dering cultivars. These results confirmes that the usage 10 g plant−1 of mycorrhizal inoculants chould be applied for increasing the growth and soybean productivity of marginal land.

The increase in black soybean production is constrained by the decreasing productive land area due to increasing population pressure. Dryland is an alternative that can be developed because of its availability. This study aimed to determine the best dosage of biochar and NPK for black soybean plants in dryland. The treatments were arranged in a randomized block design with two factors that were repeated three times. The first factor was the dose of tobacco Jengkok biochar (0, 10, 15, and 20 t ha-1) and the second factor was the dose of NPK Phonska fertilizer (0, 25, 50, and 100 kg ha-1). Soil used for this study was collected from dry land in Gading Kulon Village, Dau District, Malang Regency. Ten kilograms of the collected soil was placed in a polybag and mixed with biochar according to the treatment dose. After 7 days of biochar application, soybean seeds of Detam 1 variety were planted, and soil samples were taken to observe soil organic C, N, P, and K contents. NPK fertilizer was applied according to the treatment dose at 10 days after planting, Plant height and number of leaves were observed at 2, 4, and 6 weeks after planting. Biomass and crop yields were observed at physiological maturity at 85 days after planting. The results showed that the highest levels of organic C, total N, and K were at a dose of 20 t biochar ha-1, but the use of 15 t biochar ha-1 was the optimum dose for biomass and yield of black soybeans. The highest seed weight was obtained from 100 kg NPK ha-1.
