Pruning coffee plants is intended to stimulate generative growth that increases productivity to reach optimal. Plant Growth Regulator (PGR) makes it possible to exploit the production potential of plants. Pruning management, combined with the PGR in coffee plants, is expected to improve flowering and berry growth. The research was conducted for 7 mo from October 2017 to April 2018 at Gunung Gede, Bogor, West Java, Indonesia. A split–plot design with two treatment factors was used in this research. Pruning was placed as the main plot consisting of two levels, namely without (P0) and with pruning (P1). The PGR application was placed as a subplot, consisting of three dosages, namely without PGR (Z0), and concentrations of 0.3 mL L–1 (Z1) and 0.4 mL L–1 (Z2). The results showed, the pruning treatment significantly influenced microclimate, number of branches, B0, B1 and B2, number of berry sets, and berries. Pruning treatment had a very significant effect on microclimate, plant height, number of branches, number of coffee fruits, yields crops–1, and productivity. Interaction both significantly affected plant height and B0. The best dosage had not yet been found.

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.

Peanuts (Arachis hypogaea L.) are the second main commodity in the annual cropping pattern in lowland and dryland in North Lombok District of NTB Province. However, peanut productivity is still low, and it varies across regions, which might be due to the traditional crop management of farmers and the difference in land suitability classes. Effects of  crop varieties and land suitability on the peanut productivity have not been evaluated in the Region. Thus, this study aimed to evaluate the productivity and profitability of peanut varieties at various land classification in KLU NTB. The experiment was arranged in a Split Plot Design consisting of three classes of land suitability as main plot and six peanut varieties as sub-plot with three replications. The results showed that the land suitability classes have a significant effect on the agronomic variables of peanut varieties, including plant height, number of branches, number of pods and productivity. The highest peanut yield was obtained at suitable land class (S1), followed by moderately suitable land class (S2) and marginally suitable land class (S3) at 2.37 ton.ha-1, 2.08 ton.ha-1 and 1.71 ton.ha-1, respectively. Likewise, the R/C ratio follows a similar pattern to productivity in various land suitability classes. The highest yield (above 2 ton.ha-1) in each land suitability class was produced by Kelinci variety, followed by Tuban, Bima and Talam varieties. Those varieties have potential prospective to be developed in North Lombok Regency.
