Glycine max is a plant that can be used as a variety of food ingredients, such as tofu, tempeh, soy sauce. Glycine max production in North Kalimantan in 2017 has decreased production. One effort to increase Glycine max production is to use phosphorus fertilizer. Phosphorus fertilizer has the function of stimulating root growth especially at the beginning of growth, accelerating flowering, ripening of seeds and fruit. Therefore it is necessary to fertilize to increase Glycine max production. The purpose of this study was to determine the response of growth and yield of Glycine max plants to the dose of phosphorus fertilizer (p) and different varieties to determine the effect of the interaction between the dose of fertilizer with Glycine max varieties.This study used a factorial randomized block design with 8 treatments, 4 replications to produce 32 treatment units. The first factor is the dose of phosphorus fertilizer consisting of without using P fertilizer (P0), P fertilizer application 0.138 g per plant (P1), P fertilizer application 0.276 g per plant (P2), and P fertilizer application 0.552 g per plant (P3) . The second factor is Glycine max varieties consisting of Devon 1 varieties (V1) and Dena 1 varieties (V2). Analysis of data using variance with 95% confidence level and if significantly different, continued with DMRT test. The results obtained are that the dose of phosphorus fertilizer cannot affect the growth and yield of Glycine max plants in Dena 1 and Devon varieties 1. The use of Dena 1 varieties has a significant effect on the growth and yield of Glycine max plants in the treatment of plant height 3 mst (34.46 cm), 4 mst (46.35 cm), 5 mst (96.76 cm), main stem diameter 2 mst (0.33 cm) and plant seed weight (6.89 grams) and seed weight per hectare (1.1 tons / ha) . There was no interaction with the dose of phosphorus fertilizer and the use of varieties on the growth and yield of Glycine max plants in Dena 1 and Devon 1 varieties. Key words: Fertilizer, Phosphorus, Glycine max, North Borneo Kedelai merupakan tanaman yang dapat dijadikan berbagai macam bahan makanan, contohnya seperti tahu, tempe, kecap.

Studies have shown that that about 85% of maize farmers in Western Kenya plant local varieties with about 80% using own farm-saved seeds. The production system is characterized by late harvesting, heavy striga infestation, use of local varieties, and low-soil fertility. The objective of this study was to test an on-farm seed production system which would help improve yield and quality of farm saved seeds. The trials were set up in a factorial design fitted as random complete block design. There were 3 factors each at 2 levels: time of harvest, variety choice, and fertilizer application. Fertilizer application led to an 88% increase in yield, 54% increase in number of seeds per cob, and 14% increase in 100-seed weight. Fertilizer application also led to an increase in seed vigour and viability. Yield differences between the 2 varieties were not significant. The correlation between 100-seed weight and seed vigour was significant showing that heavy seeds were more vigourous. Nitrogen application was therefore recommended for increasing yields and for producing vigourous seeds but should be done with caution to avoid lodging as witnessed. This study also noted that farmers are rational and their decisions are usually based on strong economic considerations.

Field trials were conducted during 2017 and 2018 rainy season, to investigate the effect of nitrogen fertilizer rates and time of application on the growth and yield of cowpea. The treatment consisted of three levels of urea: 0, 40, 80 kg N ha-1 and the times of fertilizer application: during planting of cowpea, 2 weeks after planting, 4 weeks after planting and 6 weeks after planting; which were factorially combined to form twelve treatments and laid in Randomized Complete Block Design (RCBD). The results showed that, Nitrogen fertilizer rates and time of application had a significant increased on all the growth and yield parameters of cowpea in both years of trials. Application of 80 kg N ha-1 produced the highest number of cowpea leaves (134.45 and 139.23), number of branches (9.45 and 10.54), vine length (78.23cm and 80.12cm) and highest seed weight of 0.52 t ha-1 in both 2017 and 2018 trials. However, the control plots produced plants with the highest number of root nodules (14.78 and 12.49) in both years of cropping. Also, application of nitrogen fertilizer at two weeks after planting of cowpea produced the highest growth and seed weight of 0.68 t ha-1 in 2017 cropping; while in 2018 trial, application of nitrogen fertilizer at two weeks after cowpea planting produced seed yield of 0.69tha-1 which is statistically similar with application of nitrogen fertilizer on the fourth week after planting which produced 0.55 t ha-1 of cowpea seeds. The interaction between nitrogen fertilizer application rates and time of application did not showed any significant difference in cowpea yield and yield components in both years of cropping.

A 3-yr study was conducted to evaluate efficacy and soybean tolerance of cinmethylin. Cinmethylin was applied preemergence alone at 0.6, 0.8, and 1.0 kg ai/ha or in combination with metribuzin at 0.3 kg/ha. These treatments did not injure soybeans in field trials in 1984, 1985, and 1986. The combination of cinmethylin at 0.7 kg/ha and metribuzin at 0.3 kg/ha controlled more than 90% of large crabgrass, fall panicum, and yellow foxtail. Redroot pigweed and common lambsquarters control was also excellent. Residual control of all grass species was excellent for 8 weeks after preemergence application, followed by reduced control in two of the three grasses. The combination of cinmethylin and metribuzin at 0.7 and 0.3 kg/ha, respectively, significantly increased soybean yields compared to those of untreated plots. These yields were comparable with those obtained from the combination of alachlor and metribuzin at 2.0 and 0.3 kg/ha, respectively. Cinmethylin treatments had no adverse effects on soybean yield components including pods/plant, seed/pod, and seed weight. Cinmethylin shows potential as a preemergence herbicide for full-season weed control in soybean production.

Cow manure is a good source of phosphorus (P). Here, we investigated whether the amount of P fertilizer can be reduced when cow manure is applied to paddy soil based on growth, P uptake, yield, and soil P status evaluation. Treatments included unfertilized control (CK); manure plus chemical nitrogen (N), potassium (K), and P fertilizer (MNK P); MNK and 75% P (MNK ¾ P); MNK and 50% P (MNK ½ P); MNK and 25% P (MNK ¼ P); and MNK. Manure was applied at the rate of 10 t ha−1 in fresh weight base. The P fertilizer was applied at 34.9 kg P ha−1 as full dose. Treatment with MNK resulted in the same growth, P uptake, and yield as that with the P fertilizer. P uptake and yield did not respond to P input from chemical fertilizer owing to high soil Olsen P levels. Moreover, MNK could maintain soil Olsen P and total P. Manure application resulted in a positive partial P balance. These results suggest that manure application can cut P fertilizer requirements in P-rich soils, while maintaining soil P for optimal rice growth and yield. By using cow manure in rice production, farmers can conserve finite P resources.
