Abstract

Nutritional composition of large red beans (Phaseolus vulgaris L.) is good for health, much in demand by people for daily cooking, as raw material for making “dodol” or baby food, but production tends to decrease due to land conversion or soil degradation due to inorganic fertilization over do it. On the other hand, population growth continues to increase, demanding higher production. Fertilization of chicken manure can be expected to improve physical, chemical, and biological soil properties so that productivity increases.The study was conducted in the Tanjungsari SMK-PPN Field, Tanjungsari District, Sumedang Regency with a height of 850 m above sea level, Andisol soil order and type of rainfall C. The experiment was conducted from June to August 2018. The purpose of this study was to study the effect of chiken manure dosage on growth and yield of large red bean plants. The research method was a field experiment using a Randomized BlockDesign. The treatment in the form of dung manure consists of 5 levels (0, 10, 20, 30, and 40 tons ha-1) which are repeated five times.The experimental results show that the dose of chicken manure influences the plant height of 6 MST, number of leaves per plant 4 MST and 6 MST, number of pods per plant, number of seeds per plant, weight of wet seeds per plant, weight of dried seeds per plant, weight of 100 grains , and dry seed weight per plot, but no effect on other observations. The dosage of 40 tons ha-1 chicken manure gives the best dry beans weight per bean per plot even though it is not significantly different from the 30 tons ha-1 fertilizing chicken coop.

Abstract

The purpose of this study was to determine the effect of the comparison of soaking concentrations of GA 3 on the viability and vigor of seeds of two varieties of papaya. The experiment was carried out in the laboratory and screen house of the Food Crops and Horticulture Seed Supervision and Certification Center (BPSBTPH) of the Food Crops and Horticulture Service, Jawa Barat Province, Bojongsoang, Bandung Regency, at an altitude of 630 m above sea levels from April to May 2023. The design used was an environmental design using a two-factor Split Plot Design which was repeated three times. The first factor as the main plot was the variety consisting of two stages including v1 (Callina variety) and v2 (PY ASA 01 variety). The second factor as a plot for comparison of GA3 concentrations contained 5 levels including k0 (0 mgL-1 water), k1 (50 mgL-1 water ), k2 (100 mgL-1 water), k3 (150 mgL-1 water), k4 (200 mgL-1 water). The experimental results showed an interaction between soaking concentration of GA3 and variations in germination rate, germination rate, root length, plant vitality, and plant dry weight, but no interaction occurred on germination time, plant height, stem diameter, number of leaves, root volume and the extinction ratio. Root (NPA). Testing the immersion concentration of GA3 150 mgL-1 on the Callina variety gave better growth in germination power, germination speed, root length, plant fresh weight, and plant dry weight compared to the PY ASA 01 variety. Independently the variety only had a higher root volume effect on the Callina variety offspring of the PY ASA 01 variety. Meanwhile, the soaking concentration of GA3 affected stem diameter, root volume, and NPA. GA3 immersion concentration of 150 mgL-1 water produced the highest stem diameter, root volume, and NPA. Application of the optimum soaking concentration of GA3 for the Callina variety of 141.87 mgL-1 water resulted in a maximum dry weight of 0.8274 grams, while  the optimum soaking concentration of GA3 for PY ASA 01 of 150.5 mgL-1 water resulted in a maximum dry weight of 0.610 grams.
