Cowpea (Vigna unguiculata L. Walp) is one of the potential substitutes of soybean due to its similar nutritional content. This study aims to determine the optimum rate of N fertilizer for the production of cowpea, and to determine the effects of the interaction between N fertilizer rates and goat manure application on cowpea production. The experiment was organized in a split-plot with a complete randomized block design with three replications. The main plot was goat manure, i.e. 0 and 5 tons.ha-1; the sub-plot was nitrogen fertilizer with five rates (0, 50, 100, 150, and 200% of the recommended rate), i.e. 0, 22.5, 45, 67.5, and 90 kg N.ha-1. Application of N fertilizer reduced the 100-seed weight and slightly reduced cowpea yield and yield components. Application of goat manure increased seed dry weight per plant, number of pods per plant, dry pod weight per plant, seed dry weight per m2, productivity, 100-seed weight, and the harvest index. There was no significant interaction between goat manure and different rates of nitrogen in affecting cowpea growth.

Potatoes (Solanum tuberosum L.) which are comonly grown in the highland with Andisols require organic and inorganic fertilizers to maintain soil health and increase yield. The purpose of field experiment was to obtain information on the effect of vermicompost with and without NPK fertilizer on soil acidity, soil phosphor (P) availability and P uptake in potatoes shoot; as well as yield and quality of tuber. The experimental design was a randomized block design with eight treatments and three replication. The treatment consisted of a combination of vermicompost doses (5 and 10 t/ha) with NPK fertilizer doses (0; 0.5 t/ha and 1 t/ha). The two control treatments were 1) without fertilizer and 2) the method of fertilizing local farmers included 10 t /ha chicken manure and 1 t/ha NPK fertilizer. This experiment verified that vermicompost and NPK fertilizer increased plant height as well as soil P availability and acidity compared to those of control. Vermicompost has not yet substitute chicken manure to obtain the same tuber production although the percentage of marketable tuber was quite similar.

The productivity of potatoes in Indonesia is relatively low and unstable caused by unsuitable enviromental and soil conditions and bad cultivation system. This research was conducted to study the effect of NPK fertilizer dosages and soil order to soluble K, K Uptake, and yield of seed potatoes (Solanum tuberosum L.). The experiment design used a factorial randomized block design with two factors and three replication. The first factor was NPK fertilizer dosages with five levels (0, 25, 50, 75, 100% recomendation dosages) and the second factor was soil orders with two levels (Andisols and Inceptisols). The results of experiment showed that the interaction effect between NPK fertilizer dosages and soil orders had significantly effect to soluble K and K Uptake. There were independent effect of NPK dosages to diameter of potatoes tuber and independent effect of soils order to yield of seed potatoes. Andisols with 25% NPK and Inceptisols with 50% NPK were the best combination treatment to increase soluble K while treatment Inceptisols with 25% NPK was the best combination treatment to increase K Uptake. Dosages of 25% NPK was the best treatment to increase diameter of potatoes tuber while Inceptisols was the best treatment to increase yield of seed potatoes.Keywords : NPK Fertilizer Dosages, Andisols, Inceptisols, Potassium, Potatoes

The group Phureja (Solanum tuberosum L.) has been little studied in Peru, despite its culinary, nutritional and industrial quality and the risk of erosion to which it is subjected in recent decades. The objective of this research was to evaluate the total and commercial yield of tubers of fifteen potato cultivars (Solanum tuberosum, Phureja group). Traditional, yellow, and early cultivars were evaluated from Cajamarca region, Peru, to identify the most productive cultivars within the study group. The work was carried out on a plot of the Silvoagricultural Service of the Universidad Nacional de Cajamarca: 7 ° 10`LS and 78 ° 30’ LW, 2670 masl, 14.7 °C average annual temperature, 64.5% relative humidity and 651 mm of annual precipitation. Seeding was carried out at 0.90 m and 0.40 m between rows and between plants, respectively; in completely randomized block design, with three repetitions. Plant height, number of stems, number and total weight of tubers, number and weight of tubers according to categories, specific gravity, dry matter of tubers and foliage, and harvest index were evaluated. Significant statistical differences were found between cultivars for a total number of tubers, number of commercial tubers, a weight of commercial tubers, plant height, number of stems, dry matter of the tubers and harvest index. The best cultivars in tuber yield were Blanca amarilla (27.8 t/ha), Limeña huachuma (27.4 t/ha), Llanqueja (25.0 t/ha), Amarilla redonda (23.3 t/ha) and Piña amarilla (21.8 t/ha).

Potato plants are propagated vegetatively with tubers. The difficulty of getting potato seeds with tubers is an obstacle in the supply of potato seeds, to overcome these obstacles vegetative propagation with cuttings can be a solution for the supply of potato seeds. This research used a factorial Randomized Block Design (RBD). The first factor is the type of Radix Up consisting of 4 levels, namely Z0 (control), Z1 (Radix Up 1), Z2 (Radix Up 2), and Z3 (Radix Up 3), the second factor is the number of segments consisting of 3 levels namely D1 (number of segment 1), D2 (number of segment 2), and D3 (number of segment 3). Observation variables included: when the roots appeared, plant height, number of leaves, and stem diameter. The results showed that there was an interaction between Radix Up types and the number of segments on the growth of potato shoot cuttings when the roots appeared, but there were no interactions on other observational variables. The Z1D3 treatment (Radix Up 1 and segment number 3) gives the fastest average value, which is the average when the root appears 4.33 days.

And Control

The armyworm, Mythimna separata Walker is the potential insect pest of maize, causes a severe damage on the vegetative and reproductive stages of that plant. Insecticides are the common practices to manage the broad categories of the pest in a maize field. Further, these practices have been linked to farmers health, biodiversity loss and declining of predatory arthropods. However, pest management by adopting a tool of integrated pest management is one potential option to reduce the pesticide in maize fields. Field experiments were conducted in winter maize with the aim of evaluating the potential bio-rational pesticides to manage the armyworm. The studies were conducted for two consecutive years in 2015/16 and 2016/17 at Rampur, Chitwan. Treatments were: Metarrhizium anisopliae (0.2ml/lit water), Nuclear Polyhedrosis Virus (NPV) ( 2.5gm/lit water), Spinosad 45% SC (0.25ml/liter of water), Multineem (Azadriachta indica) (2 .0 ml/ liter water), Furadan 3G (3-4g/ Whorl application), Lara (Chloropyriphos 50 EC + Cypermethrin 5 EC) (1.0 ml/liter of water), Magik (Imidacloprid 17.8% (0.5ml/liter of water) and Control. The experiments were completely randomized block design with three replicates. Spinosad treated plots demonstrated the lowest damage (0.884%) followed by Magik (1.27%) which was significantly lower (P< 0.05) than other treatments in 2015/2016. However, in 2016/2017, Spinosad treated plot also showed the significantly lowest damage (1.67%) followed by Lara plots (2.67%), both of these were significantly different (P< 0.05) to Metarhizium and control plots, but similar to the other treatments, but not significantly so. Maximum yield was recorded in spinosad treated plots (9.8 t/ha and 9.12 t/ha) followed by Lara treated plots (9.17t/ha and 8.69t/ha) and were lowest in control plots (4.55 t/ha and 7.18 t/ha) for both years. Hence, Spinosad (soil actinomycete bacterium, Saccharopolyspora spinose ) has the potentiality to maximize the maize yield and also potentially to the reduce the pesticide consumption and incurred cost caused by the pesticide use. Such a safe and eco-friendly insecticide has the potential to replace the synthetic pesticide and provide the benign environment to the natural predators and service providing units of multiple ecosystem services in maize agro-ecosystem.

Field experiments were conducted during rabi seasons of 2011-12, 2012-13, 2013-14 and 2014-15 at C-unit research farm of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India to study the effects of different levels of nitrogen on the productivity of newly released potato (Solanum tuberosum L.) cultivars under lower Gangetic plains of West Bengal. The experiment was laid out in a factorial randomized block design with four replications having ten treatment combinations viz. two levels of newly released cultivars (V1 - Kufri Himalini and V2 - Kufri Shailja) as factor A and five levels of nitrogen (N0 -0 kg ha-1, N75 -75 kg ha-1, N150 -150 kg ha-1 N225-225 kg ha-1 N300 -300 kg ha-1) as factor B. Experimental results revealed that highest tuber yield (25.77 t ha-1) was recorded with Kufri Himalini receiving 300 kg N ha-1 followed by 24.64 t ha-1 and 23.64 t ha-1 with 225 kg N ha-1 and 150 kg N ha-1 respectively which is quite higher than the state average of 22.02 t ha-1 obtained from the state recommended dose of 200 kg N ha-1, 150 P2O5 ha-1 and150 K2O ha-1. Thus recently released variety Kufri Himalini, having moderate resistance against late blight, which is a serious problem in the state at present can be a better option for the farmers of the state to raise the potato production. Kufri Himalini produced significantly higher (14.1%) total tuber yield over Kufri Shailja and it was found to be more acceptable to the farmers in terms of production of marketable tuber (> 75 g grade). Grade wise tuber yield of potato was significantly influenced by N levels. Irrespective of cultivars application of 300 kg N ha-1 along with recommended dose of P and K recorded the highest total potato tuber yield (23.55 t ha-1) which was found statistically at par with the application of 225 kg N ha-1 and 150 kg N ha-1. Nitrogen fertilization improved the tuber yield of potato by 49.5 to 82.1% over control. Kufri Himalini was more responsive to fertilizer nitrogen than Kufri Shailja as it recorded higher agronomic efficiency (AEN), apparent recovery (REN) and physiological efficiency (PEN) at all nitrogen levels. There was a positive balance of nitrogen found in all treatments. Net gain of soil N was highest with Kufri Himalini receiving 150 kg N ha-1. Kufri Himalini gave highest net return with 300 kg N ha-1.SAARC J. Agri., 13(2): 121-130 (2015)
