Soil profiles are generally heterogeneous and consist of various horizontal layers due to geological processes, the formation of crusts, or other artificial or man-made activities. To quantify infiltration into these heterogeneous soil profiles, the Modified Green-Ampt Model (MGAM) is a physically-based hydrologic model that can efficiently perform under both steady and unsteady rainfall events. Based on the secondary data, this study sought to determine the effect of changing soil layers (soil textures) on infiltration rates and cumulative infiltrations in in both laboratory and field settings. Different scenarios were analyzed by rearranging soil layers and evaluating their impacts on corresponding infiltration rates and cumulative infiltrations. Simulations were run with HYDROL-INF software environment using MGAM. Three scenarios were considered for a laboratory experiment with two different types of soil texture coupled with five different soil profiles. Similarly, four scenarios were considered for the field experiments with five different types of soil texture couple with eight different soil profiles. The simulated infiltration rates and cumulative infiltrations were found to vary with soil layer change scenarios. The simulated cumulative infiltrations, ponding times, infiltrating rates at ponding, and total depth of wetting front at ponding of a five-layered laboratory soil column were identical for the three scenarios. Simulated cumulative infiltrations were 33.16, 23.65, 21.29, and 42.77 cm, respectively, for scenarios (combinations) 1, 2, 3, and 4 in the eight-layered soil profile in the field scenarios. Infiltration rates among scenarios at ponding were identical (0.46 to 0.53 cm/h) with field scenario data.

Oil palm (Elaeis guineensis) is one of the commodity crops and mostly found in tropical lands. This study aimed to analyze the current and potential land suitability for oil palm using the geographic information system (GIS) technique. The study was conducted in the Ranau area, State of Sabah, Malaysia. Field activity was carried out to collect soil samples and land information in the study area. Land suitability was then assessed using the matching method and GIS software was employed to produce a land suitability map for oil palm. The results indicated that the current land suitability classes in the study area were highly suitable (S1) with a total area of 99,118 ha (27.4%), moderately suitable (S2) with 110,108 ha (30.4%), marginally suitable (S3) with 109,533 ha (30.2%), currently not suitable (N1) with 2,728 ha (0.7%), and permanently not suitable (N2) with 40,693 ha (11.3%). While the potential land suitability classes showed highly suitable (S1) was 198,206 ha (54.7%), moderately suitable class (S2) was 123,281 ha (34%) and permanently not suitable (N2) was 40,693 ha (11.3%). Suitable areas that could be planted with oil palm included the gently sloping flank and the low gradient slope margin. Availability of nutrients and work capability were the dominant limiting factors in the study area. The output of this study recommends that the Ranau area had the potential for oil palm although it still needs land improvements for sustainable oil palm cultivation.

The content of polysaccharides, polyphenols, proteins, and RNA compounds is the main problem often found in Plants DNA isolation, which inhibit the process of DNA isolation. Comparing the methods of plant DNA isolation is necessary for obtaining the DNA with good quality, purity, high concentration and efficiency time and cost. This study aimed to determine the best DNA isolation method that derived from leaves of a potential anti-cancer Rodent Tuber (Typhonium flagelliforme) plant by comparing the conventional DNA isolation method (cetyl trimethyl ammonium bromide/CTAB) and 2 commercial kits (Promega Wizard™ Genomic DNA Purification Kits, and Geneaid Genomic Mini Kit). The results showed that the CTAB method yielded a higher amount of DNA (>100 ng/µL) at the cost of 0.49 USD per sample, in comparison with Promega method (69.19 to 157.68 ng/µL) at 3.28 USD per sample and Geneaid method (8.15 to 18.52 ng/µL) at 2.06 USD per sample. Based on the purity of isolated DNA (A260/280), CTAB method produced relatively similar DNA quality to Promega kit (1.8-2.0). On the other hand, Geneaid method resulted in a lower purity value at 1.15 to 1.60.

Red ant (Dorylus orientalis Westwood) is the most destructive insect pest of potato tubers in the field in Nepal. A field experiment was conducted at Bhatkada, Dadeldhura district, Nepal in 2020 to determine the efficacy of various biopesticides and chemical insecticide on red ants. The plot size in this experiment was 106.7 m2. Five treatments viz. Chlorpyriphos 20% EC (2 mL L-1 water), Banmaara (2 kg plot-1), Cow urine (2 L 6 L-1water plot-1), Agave (25 g tuber-1) and Control (no treatment) were evaluated in randomized complete block design with four replications. The data on plant height and the number of leaves were taken at 45, 60, and 75 days after planting (DAP). The data on slightly and severely infested tubers were taken after harvesting of potato. The results showed that Chlorpyriphos treated plots gave the lowest values of traits viz numbers of slightly infested tuber (91,500 ha-1), severely infested tubers (12,500 ha-1), weights of slight infested tubers (7,700 kg ha-1) and severely infested tuber (1,130 kg ha-1). Among the botanical pesticides, Agave treated plots provided the second lowest values of numbers of slightly infested tuber (145,500 ha-1), severely infested tubers (37,400 ha-1), weights of slight infested tubers (13,400 kg ha-1) and severely infested tuber (3,110 kg ha-1). The results showed that the Agave treatment provided the highest marketable yield (50,900 kg ha-1). Thus, Chlorpyriphos and Agave could be used to efficiently protect potato tubers from red ant in potato field.

The vast area of paddy crop in Anantnag district (Jammu and Kashmir) has been converted for the construction of houses, roads and especially for horticultural purposes. The cultivation of paddy has been an old cultural heritage of Anantnag district as well as for the Kashmir valley as a whole, while the farmers are increasingly finding it less profitable in recent times. The present study used both primary (Survey) and secondary data from different sources with an aim to highlight the issue of diversifying of food crops (Paddy) towards cash crops (Apple) in district Anantnag. The findings from the study reveal that 6908 hectares of agricultural cropped area is shifted towards the horticultural cropped area, as agricultural crops (paddy) have low comparative advantage over horticultural (Apple). Paddy land under surveyed farmers has registered a significant decrease from 330 canals (83.75%) in 2000-01 to 158 canals (40.11%) in 2014-15, therefore showing an absolute change of -172 canals. The primary survey further reveals that 09 (30%) of the respondents says less profit is the main reason behind the shift, followed by irrigation (drought) problems 07 (23.34%) and 14 (46.66%) respondents says both reasons are responsible behind shift of Paddy to Apple cultivation in the region.

Shallots are one of the horticultural commodities that are highly expected to be cultivated intensively. The need for shallots nationally increases from year to year. These needs cannot be increased by increasing national production. One thing that can be done to make shallots available is to use good varieties and provide growth regulators with auxin using botanical seeds (True Shallot Seed) as a seed source. This study aims to determine the effect of the interaction between varieties with auxin concentration on the growth and production of shallots. This research was carried out in the Exfam Land, Faculty of Agriculture, Hasanuddin University, Makassar, South Sulawesi Province, from August to November 2021. This study used a Split plot design which consisted of two factors, the first factor as the main factor being different plant varieties, namely Lokananta, Maserati, and Sanren. While the sub-plot is the concentration of Auxin consisted of 4 levels, namely 0 mg L-1,100 mg L-1, 200 mg L-1, and 300 mg L-1 . The experimental results showed that the red onion variety using the variety with a concentration of 200 mg L-1 gave the best results on the fresh weight of shallots (123.80 g), the dry weight of shallots (93.77 g), the tuber weight of (86.63 g/plot), tuberproduction (4.51 kg/plot), and productivity (19.50 ton ha-1). The treatment of shallot varieties using the Sanren variety gave the best results on the parameters of the number of bulbs (1.89 bulbs). The application of auxin at a concentration of 300 mg L-1 gave the best results on the tuber diameter parameter of 28.42 mm.
