The purpose of this study was to determine the dose of bovine bone ameliorant on the growth and yield of sorghum in swampland and to determine the interaction of ameliorant and varieties of sorghum cultivated in swampland. This research is expected to provide information about the effect of giving cow bone ameliorant to several varieties of sorghum in swamps. The research was carried out from February to April 2020, in Gunung Alam Village, Arga Makmur District, Bengkulu Utara Regency. The study used a Completely Randomized Block Design with 12 treatments and 6 replications. The treatment used in this study consisted of two factors, namely the first factor was bovine bone ameliorant with 2 levels, namely bovine bone ameliorant treatment and without beef bone ameliorant treatment. The second factor of sorghum varieties, namely Numbu, Super 1, and Super 2. The results showed that the 50 g dose of beef bone ameliorant gave the highest value in this study.</p> Parwito Parwito Edi Susilo Noteka Illahi Eny Rolenti Togatorop Hesti Pujiwati Copyright (c) 2023 Parwito Parwito et al. 2023-07-31 2023-07-31 16 2 65 76 10.29303/caj.v16i2.955 https://cropagro.unram.ac.id/index.php/caj/article/view/957 <p>The purpose of this research was to determine aroma quality of rice and nutritional contents of upland rice of Pare Wangi variety under various levels of soil moisture and salinity, and determine correlation between the aroma quality and the nutritional content of rice. The research was started with planting seeds of Pare Wangi variety in the pot experiment. Experiment was conducted using Completely Randomized Design (CRD) that was arranged factorially by three replications.&nbsp; The samples of harvested grain&nbsp; then were taken&nbsp; to the laboratory to be tested&nbsp; for the aroma quality and other qualities of the rice. The aroma quality was determined on the basis of the aroma score of organoleptic-test results and 2-AP content of&nbsp; the rice, while other rice qualities include: percentage of white rice and&nbsp; head rice, rice water content, content of ash, fat, carbohydrate, protein, starch, amylose, and amylopectin. Data were analyzed by analysis of variance, HSD of 5% significantly level, and descriptive.&nbsp; Then, to find out the relationship between aroma quality and nutritional contents&nbsp; were carried out simple correlation analysis. The results showed that the decrease in soil moisture level caused a decrease in the quality of milled grain and the nutritional contents of rice, but did not show a significant decrease in the protein and carbohydrate content of rice.&nbsp; Soil moisture at 75% FC level caused the best 2AP content of rice and aroma score. The increase in salinity with the addition of NaCl salt up to 4 g NaCl&nbsp;&nbsp;&nbsp; kg^-1 soil caused a decrease the quality of milled grain, content of ash, fat and protein. Salinity level of 1 and 2 g NaCl kg^-1 soil gave the highest 2AP content of rice, but the effect&nbsp; was not significant on the rice aroma score. Both 2AP content and aroma score of rice were not significantly correlated with all nutritional contents of rice analyzed.</p> I Gusti Bagus Adwita Arsa H.J.D.

In addition, NTB is also one of the target areas for increasing national maize production. This study aims to determine the yield yield of several varieties of maize given a mixed package of organic, inorganic and mycorrhizal fertilizers. This research was conducted from May to August 2020 in Midang Village, Gunung Sari District, West Lombok Regency, Microbiology Laboratory and Soil Physics and Chemistry Laboratory, Faculty of Agriculture, Mataram University. The method used in this study was a randomized block design with 5 treatments, namely V1 (P8IS variety), V2 (P8DPP variety), V3 (Gumarang variety), V4 (Lamuru variety), V5 (Sukmaraga variety). Each treatment was repeated 3 times in order to obtain 15 experimental plots. The results showed that maize varieties given organic, inorganic and mycorrhizal fertilizers had a significant effect on growth, yield of maize, nutrient status and nutrient uptake, number of mycorrhizal spores and root colonization by mycorrhizae. Sukmaraga variety has better growth and yield than other varieties, this is reflected in the growth parameter indicators and yield parameter indicators, namely harvest dry ear weight per plant (271.5 g), dry ear weight per plant (255 g), length ear (16.5 cm), ear diameter (5.3 cm), seed dry weight per plant (180 g), and weight 1000 seeds (288 g).</p> Muhamad Muhajir Wahyu Astiko Hanafi Abdurachman Copyright (c) 2023 Muhamad Muhajir et al. 2023-07-31 2023-07-31 16 2 90 99 10.29303/caj.v16i2.768 https://cropagro.unram.ac.id/index.php/caj/article/view/807 <p>This study was aimed to determine the influence of various kinds of manure on N and P uptake on Golden berry (<em>Physalis angulata</em> L.). The experiment was conducted in a plastic house in Terong Tawah, Subistrict of Labuapi, West Lombok regency. The experiment was set up using a Completely Randomized Design (CRD) with 6 treatments namely A0 (control), A1 (chicken manure), A2 (goat-manure, A3 (buffalo manure), A4 (horse manure), and A5 (cattle manure) which were repeated 3 times. The results showed that application of manures significantly affect fresh weight of stover, the dry weight of stover, N and P uptake.

In certain season, such as the rainy season, production tends to be low due to the low yield of chilies. Therefore, it is important to get the cultivation technology of cayenne pepper outside the season. This research aimed to study growth and yield of two varieties of cayenne pepper grown off-season treated with different concentrations of POMI foliar fertilizer. One experiment was carried out in October 2020 to March 2021 in a dryland of Gumantar Village, Kayangan District, North Lombok Regency. The factors tested were varieties (Sret and Taruna) and POMI foliar fertilizer concentrations (0%, 1.0% and 1.5%). The treatments were arranged using a factorial randomized block design (RBD) with three replications. The results showed that the variety and concentration of POMI leaf fertilizer interacted in affecting the number of flowers and the number of fruits. The highest number of flowers and fruit was produced by Taruna variety which was treated with POMI foliar fertilizer at 1.5% concentration. Taruna variety showed a better growth and yield than Sret while the concentration of POMI foliar fertilizer which produced the best growth and yield was 1.5%. To get high yields in off-season chili cultivation, it is recommended to grow Taruna varieties and be treated with POMI foliar fertilizer with a concentration of 1.5%.</p> Merita Eka Armiati I Komang Damar Jaya Mery Windarningsih Copyright (c) 2023 Merita Eka Armiati et al. 2023-07-31 2023-07-31 16 2 115 126 10.29303/caj.v16i2.818 https://cropagro.unram.ac.id/index.php/caj/article/view/819 <p>Cayenne pepper is one of the horticultural commodities that its production is low in the rainy season (off-season) due to the high potential for flower abortion and plant disease attacks. This study aimed to determine the effect of manure plus and varieties on the growth and yield of some cayenne pepper varieties planted off- season. The experiment was carried out in the 2020/2021 rainy season in Gumantar Village, Kayangan District, North Lombok Regency. The treatments were arranged using a Split Plot design with three replications. The main plot was manure treatment with 2 treatment levels, with and without manure plus, while as sub-plots were varieties, Taruna, Sret and Mutiara Bumi. The results showed that plant height and number of leaves at the age of 56 DAP and 98 DAP were significantly affected by manure plus treatment, and by&nbsp; variety too. The effect of varietal treatment showed significantly different on yield variables, such as fruit weight per plant and fruit weight per plot. The highest yield was shown by Taruna variety while Sret and Mutiara Bumi varieties did not show different results. There was an interaction between the treatment of manure and variety on the variable number of flowers, number of fruits and percentage of flower abortion. The best interaction effect occurred in the treatment of Taruna variety treated with manure plus. From the results of this study, it can be suggested to grow Taruna variety treated with manure plus to obtain high yields of cayenne pepper grown off-season on drylands.</p> Hidayatul Fathi I Komang Damar Jaya I Wayan Sudika Copyright (c) 2023-07-31 2023-07-31 16 2 127 138 10.29303/caj.v16i2.819
