The Right

The use of fertilizers with the right amount could increase  the growth and yield of lowland rice. This research aims to determine the effect of fertilizer use on the growth and yield of lowland rice. The experiment was conducted on the farmers field in Sungai Lareh, Koto Tangah District, Padang City of West Sumatera Province, from July to December 2009. Research used Randomized Completely Block Design (RCBD) with five replications. The treatments tested were: (A) Urea + KCl, (B) Urea + SP36, (C) Urea + SP36 + KCl, (D) without fertilizers (as control). The dosages of fertilizer were: 150 kg Urea, 100 kg SP36, and 75 kg KCl per hectare. The results showed that the use of a complete fertilizer (Urea + SP36 + KCl), or combination of Urea + KCl, or combination of Urea + SP36 had a significant effect on the growth and yield compared to without fertilizer treatment. The use of Urea + KCl resulted about 5.04 t/ha dry grains harvest (DGH) or increased grain yield as much as 14.03%, and the use of Urea + SP36 gave the results as much as 5.69 t/ha DGH or increased grain yields as much as 28.73%, and use of a complete fertilizer Urea + SP36 + KCl gave the results 6.13 t/ha DGH or increased yields about 38.69%. Whereas, without fertilized gave only grain yield as much as 4.42 t/ha DGH.

Fertilizers and fertilization technology have important roles in increasing crop production including lowland rice. In response to the issue, a field experiment was conducted to study the effects of micronutrients on growth and yield of lowland rice. The experiment was carried out at Cihideung Ilir Village, Dermaga Sub-district, Bogor Regency from November 2015 until March 2016. The experiment consisted of 8 treatments, namely control (without fertilization), NPK-standard, NPK-standard  + ¼ dosage of Hortigro Rice fertilizer, and ¾ NPK  + ¼  until 11/4 dosages of Hortigro Rice fertilizer as a source of macronutrients N, P, K and micronutrients of Mn, Cu, Zn, B, and Mo. The treatments were arranged in a Randomized Block Design with 3 replications. Parameters observed during the research were plant height, tiller number, and yield of grain and straw of INPARI-32 lowland rice as crop indicator. The  results  showed that among other treatments, the highest plant height was resulted from the application of ¾ NPK-standard + ¼ Hortigro Rice, i.e. around 124 cm at 60 days after planting. The highest harvesting dry weight of grain and straw were observed in NPK-standard + 1/4 of Hortigro Rice fertilizer treatment, i.e. around 9.0 Mg ha-1 and 25.9 Mg ha-1, respectively. This yield showed a significant difference with ¾ NPK-standard combined with ¾  -11/4 dosages of Hortigro Rice. The highest  dry weight of  milled grains was  resulted in the application of  ¾ NPK-standard + 1/2 Hortigro Rice, i.e. around 7.3 Mg ha-1, which is significantly different from that in ¾ NPK-standard combined with 1.0 - 11/4 dosages of Hortigro Rice treatments, while the highest dry weight of straw was provided by NPK-standard, i.e. around 14.0 Mg ha-1. The highest  dry weight of 1000 milled grains and ratio of  dry weight of milled grain to straw were provided by ¾ NPK-standard + 1/2 Hortigro Rice around 32.0 gram and  0.63, respectively. The results indicated that the application of micronutrient fertilizer of Hortigro Rice in combination with NPK fertilizers can potentially increase lowland rice productivity due to the micronutrients content of Mn, Cu, Zn, B, and Mo in it.

Rice planting on dry and wet seasons faces a specific climatological characteristic, which affects directly on rice growth and yield. Fifteen rice genotypes were evaluated for their seasonal planting adaptation at Sukamandi Experimental Station, Subang, West Java, during the dry and wet seasons of 2009-2010.<br />Randomized complete block design with three replications was applied on the experiment. Plot size was 4 m x 6 m and plant spacing was 20 cm x 20 cm. Standard agronomic practices were applied on both planting season experiments. Data were collected for major morphological traits, days to grain maturity and grain yield, measured on wet and dry basis (11% moisture content). Data were analysed for analyses of variance for each season and for combined seasons, and mean values separation of the variable used the 5% Duncan Multiple Range Test. Correlation between grain yields and morphological variable data were computed for each season and for combined seasons. The correlation coefficients of variables and grain yield were partitioned into direct and indirect causes using path analyses. Combined analyses of variances indicated significant effects of genotypes, seasons and genotypes x seasons interaction for almost all variables, including grain yields, suggesting there were seasonal adaptation specificity among genotypes. Five genotypes were identified as suitable for dry season planting, and nine<br />genotypes as suitable for wet season planting. Among those genotypes, three genotypes, namely Mekongga, Inpari-10 and OM 5240 were suitable for both dry and wet season planting. Ciherang and Cigeulis varieties were more suitable for dry season, while Cibogo, Inpari-1, Inpari-3, Inpari-5, and Inpari-8 were more suitable for wet season planting. Adopting the most productive rice varieties for planting on dry or wet season as was suggested on this research should increase rice production substantially. To facilitate the availability of varieties adapted<br />for a specific planting season, rice breeding should purposedly apply a directional selection of lines suitable for specific planting season, starting on the early generation of selection. <br />

On-Farm trail was conducted in Longleng district of Nagaland during the kharif season of 2014-15 and 2015-16 to find out the most suitable nutrient management practices viz. recommended doses of fertilizers (RDF) 80:60:40 kg NPK/ha, locally available weed biomass (Eupatorium @ 10 t/ha) and farmers practices at farmers field of Krishi Vigyan Kendra, Longleng, Nagaland. The experiment was laid out in Completely Randomized Block Design. Result revealed that growth and yield parameters were recorded maximum under RDF and followed by Eupatorium @ 10 t/ha compared to farmers practice. The maximum grain yield (3590 kg/ha) was with RDF closely followed by weed biomass @10t/ha (3270 kg/ha) over the farmer's practices (2730 kg/ha), respectively. Grain yield was increased by 31.5 % in RDF and 11.8 % in Eupatorium @ 10 t/ha compared to the farmer's practices. Similarly, production efficiency was recorded the highest with RDF (28 kg/ha/day) followed by Eupatorium @ 10 t/ha (25.5 kg/ha/day) and farmers practice (21.3 kg/ha/day). With respect to economics, the maximum net returns and benefit: cost ratio (B: C ratio) were recorded with RDF (Rs.18850/ha and 1.91) as compared to other treatments. Economic efficiency was also noted highest under RDF (Rs.147.27/ha/day) followed by Eupatorium @10 t/ha (Rs.128.36/ha/day). Hence, it may be concluded that the farmer’s practices can be replaced with the adoption of RDF or locally available weed biomass (Eupatorium) as a source of nutrition for achieving the higher productivity and profitability of the lowland rice under the mid-hill altitude condition of Nagaland

Weed Removal

Weed problem appears to be the most deleterious factor causing between 25 and 60% reduction in potential yield of cowpea. Field trials were therefore conducted to study the effect of inter-row spacing and period of weed interference on growth and yield of cowpea (Vigna unguiculata (L) Walp) at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta (07° 15'; 03° 25' E) in South Western Nigeria during the early and late wet seasons of 2009. The experiment consisted of eight main plots of weed interference which included initial weed removal for 3, 6, 9, and 12 weeks after sowing (WAS) and subsequently weed –infested until harvest as well as initial weed infestation for corresponding periods and thereafter kept weed free until harvest. There were also sub-plot treatments of three inter-row spacing of 60, 75, and 90 cm. All treatments in different combinations were laid out in a split-plot design with three replications. In both trials, the use of inter-row spacing of 60 cm resulted in significant reduction in weed growth as evident in lower weed dry matter production and subsequent higher cowpea pod and grain yields than those of 75 and 90 cm inter-row spacing. Initial weed infestation of up to 3 WAS did not have any adverse effect on crop growth and cowpea grain yields provided the weeds were subsequently removed. On the other hand, cowpea grain yield loss was not significantly averted by keeping the crop weed free for only 3 WAS without subsequent weed removal. In this study, initial weed-infestation for 6 WAS and beyond significantly depressed various crop growth parameter and cowpea grain yield compared with the crop kept weed free throughout its life cycle. In order to obtain optimum yields similar to that of the weed free cowpea field, it was required to keep the crop weed free for 6 WAS and beyond. However, frequent weeding beyond 9 weeks after sowing did not improve cowpea yield significantly and as a matter of fact it may even result in reduction of cowpea grain yield due to mechanical damage of hoe weeding. The practical implication of this finding is that early weeding starting from 3 WAS is very crucial for cowpea production while the critical period of weed removal for optimum yield in cowpea is between 3 and 9 WAS in the forest-savannah transitional zone of south Western Nigeria.

The use of natural hormone of sprout extract, coconut water, and banana stem extract and application of cow biourine has been introduced as an innovation to reduce the use of chemical fertilizers to increase the productivity of shallot. This study aims to compare the growth and yield of shallot with chemical fertilizer treatment and that of shallot treated with combination of natural hormone and cow biourine. The study was conducted in Temon Wetan, Temon, Kulon Progo, Special Region of Yogyakarta using a Complete Randomized Block Design, which consists of two factors and one control (chemical fertilizer). The first factor is a natural hormone: sprout extract, banana stem extract and coconut water. The second factor is the concentration of cow biourine: 30%, 40%, and 50%. Data were analyzed using diversity at 5% level, Orthogonal Contras at 5% level and DMRT Test with 5% level. It was revealed that the control group with a combined treatments was not significantly different from the growth and yield of shallot of the group with chemical fertilizers. Types of treatments with natural hormone and cow biourine concentrations provided the same growth and yield as that of chemical fertilizer.

<p>Rate of NPK fertilization on rice using NPK compound fertilizer needs to consider soil nutrient status and plant nutrient requirement. The research was aimed to determine the optimum rate of compound fertilizer and the effect of enriched S nutrient of NPKS compound (15-15-15-5S) and NPK compound fertilizer (15-15-15) on the growth and yield of rice. The experiments were conducted at two sites in Galuga, Ciampea Bogor, West Java from April to September 2013, using randomised complete block design with 3 replications. Experiment at site I consisted of 9 treatments: six levels of fertilizers NPKS i.e. 0; 150; 300; 450; 600; and 750 kg/ha, standard fertilizer, NPK compound fertilizer equivalent to standard, and standard fertilizer plus S. Rate of urea, SP-36, and KCl for standard fertilizer treatment was respectively 250, 75, and 50 kg/ha. At site II the treatments consisted of 6 levels of NPK compound fertilizer i.e. 0; 150; 300; 450; 600; and 750 kg/ha and the standard fertilizer with rate of 250 kg/ha of urea, 50 kg/ha SP-36, and 75 kg/ha KCl. Plot size was 4 m x 5 m planted with Ciherang variety. Data collection included chemical properties of soil before and after the experiment, plant height, number of tillers, straw weight, and dry grain weight and the nutrient uptake. The effectiveness of fertilizer was calculated by RAE (Relative Agronomic Effectiveness). Results showed that fertilizer NPKS (15-15-15-5S) at 600 kg/ha effectively increased dry grain weight from 3.63 t/ha to 4.67 t/ha, but was not significantly different from a standard fertilizer treatment. It increased dry grain weight by 29% compared to control. NPK fertilizer (15-15-15) effectively promoted growth and dry grain weight equivalent to standard fertilizer at rate of 300-750 kgha. The optimum rate of NPK compound fertilizer (15-15-15) was 440 kg/ha as was shown with the production performance of 4.12 t/ha with RAE by 58%. NPKS compound fertilizer with rate of 750 kg/ha showed the highest uptake of N, P, and K nutrients and significantly increased the available P in the soil. Whereas NPK compound fertilizer with a rate of 600 kg/ha indicated the highest P nutrient uptake. Fertilizer enrichment with sulfur on NPKS fertilizer (15-15-15-5S) did not significant affect on grain dry weight.</p>

The use of biostimulants in the treatment of soybean seeds can provide beneficial effects on the crop due to the synergism between the organic components present in products from natural compounds. Due to the scarcity of results of research on biostimulants in the treatment of soybean seeds, the objective of this study was to evaluate the effects of doses of a biostimulant in the treatment of seeds, on agronomic characteristics, productivity components and profitability of soybean culture. Therefore, two experiments were carried out in the field in the 2016/17 and 2017/18 harvests, using a randomized block design with six replications and four treatments referring to doses of 0.00; 0.05; 0.10; and 0.15 L 100 kg seeds-1. The agronomic characteristics of soybeans, grain yield and profitability of using the biostimulant were evaluated. From the obtained results, it can be seen that the dose of 0.15 L 100 kg seeds-1 provided greater profitability in both harvests. In addition, doses above 0.12 L 100 kg seed-1 provide higher grain yields and a higher grain mass, in addition to other productivity components.
