Abstract

Soybean (Glycine max (L.) Merr.) was one of the food commodities whose the demand has not been fulfilled. Local soybean production is predicted to stagnate in the range of 520,000 tons, while consumption is estimated to reach 3.07 million tons. The causal factor is suspected to be due to limited soil water supplies and unsuitable physical properties of the soil, especially in Vertisol . The purpose of this study was to determine the effect of organic fertilizer doses on several soybean varieties on Vertisol. The study design uses the Split Plot Design. As Main Plot are Varieties (Grobogan, Burangrang, and Baluran Varieties), while as Sub Plots are Doses of Organic Fertilizers (0, 10, 20, and 30 tons / ha). The data obtained were analyzed by Analysis of Varians. Then carried out further tests with the DMRT test (Duncan Multiple Range Test) at a significant level of 5%. The results showed that the administration of organic fertilizer at a dose of 30 tons / ha increased the yield of all soybean varieties tested, while the administration of organic fertilizer below that dose only increased in vegetative growth. Baluran varieties provide the best response to the provision of organic fertilizer, following Burangrang, and Grobogan.

Abstract

The reality in the field shows that not all lowland rice varieties which include local varieties, old superior varieties, new superior varieties and new types of varieties are suitable for organic cultivation because each group of varieties has different physiological characters. This research was carried out with the aim of determining the suitable lowland rice varieties for organic cultivation based on physiological characters. The research was carried out through pot experiments to determine the suitability of lowland rice varieties including local varieties, old varieties, new varieties, and new types of superior varieties in organic cultivation based on their physiological characteristics. with an altitude of 113 m above sea level with inceptisol soil types and tropical climate. The results showed that organic cultivation did not reduce root permeability to N uptake except for Cisedane variety. Organic cultivation lowered the KPK for the roots of the IR64, Cianjur and Mentikwangi varieties, but increased the KPK for the roots of the Pandanwangi and Cisedane varieties. The uptake rate of N, P, and K roots in organic cultivation was not different from conventional cultivation. The uptake of N roots in organic cultivation was lower than conventional cultivation. The uptake of N, P, and K by roots between varieties was not different. Organic cultivation reduced the uptake of N stems of varieties IR64, Mentikwangi and Cisedane. Among the varieties tested, there was no difference in N uptake in conventional or organic cultivation. Organic cultivation reduced the P uptake of stems of IR64 and Mentikwangi varieties, Organic cultivation decreased total N uptake of Mentikwangi varieties. In conventional and organic cultivation, the plant N uptake of all tested rice varieties was no different.

Abstract

Cayenne pepper (Capsicum frutescens L.) was a plant that has high economic value. The application of phosphate fertilizers in inorganic forms is not friendly to the environment and is slowly available to plants. This research was carried out from October 2019 to January 2020 in Pancot Village, Kalisoro Village, Tawangmangu District, Karanganyar Regency with an altitude of 1200 meters above sea level and Andisol soil type. This study used a completely randomized design with two treatment factors (factorial), namely the first factor is the dose of fast soluble phosphate fertilizer namely 0 kg/ha (no SP36 fertilizer), 150 kg/ha (one application), 150 kg/ha (3 times application), 100 kg/ha (3 times application), and 50 kg/ha (3 times application). The second factor is the dose of chicken manure consisting of 2 levels, namely 0 tons/ha (no chicken manure), and 40 tons/ha. Parameters observed were plant height, flowering age, fresh weight of the plant, number of branches, and number of fruit per plant. The results showed that fast soluble phosphate fertilizer had a very significant effect on plant fresh weight and fruit number. Manure treatment has a significant effect on the parameters of plant height, fresh weight of the plant, total fruit per plant. The interaction of fast soluble phosphate fertilizer and manure had a significant effect on flowering age, fresh weight, and the number of fruits per plant. The best results were in the interaction of fast soluble phosphate fertilizer with a dose of 50 kg/ha and 40 tons/ha of manure.

Abstract

Tea (Camellia sinensis Lidenam.) is a plant whose shoots are taken for a beverage. Tea plants are susceptible to attack by Plant Pest Organisms (OPT) which have the potential to reduce yields by up to 30%, in severe attacks can reduce production by up to 50%. The purpose of this study was to determine the effect of tobacco biopesticide treatment on the intensity of attack and the percentage of pest attack (Thrips tabaci lidenam) on the shoots of tea plants. The study was carried out at PT Rumpun Sari Kemuning in Kemuning, Ngargoyoso, Karanganyar, on April 1 - June 29, 2021. This study used a Completely Randomized Block Design method with 6 treatments and 4 replications. The first treatment was J0: Control, J1: 0.05% Biopesticide Concentration, J2: 0.1% Biopesticide Concentration, J3: 0.15% Biopesticide Concentration, J4: 0.20% Biopesticide Concentration, J5: 0.25 Biopesticide Concentration %, the biopesticide treatment was carried out 12 times. The results of this study showed that the use of tobacco biopesticide 0.20% gave the best results against the percentage of pest attacks, namely 40.00%. And the use of 0.25% biopesticide gave the best results against the percentage of pest attack intensity of 8.75%.
