Chickpea is one the most important legume crops in Mediterranean semi-arid regions and its sustainable production strongly depends on the nutrient management and water availability. Soils of these regions generally have high pH, and low organic matter, which reduce the availability of micronutrients and led to multi-micronutrient deficiencies. For estimating the effect of integrated application of different levels of organic fertilizer (zero, 20 t ha-1, 40 t ha-1) and micronutrient fertilizers (Zn, Fe) on agronomic traits and yield components of chickpea, an experiment was carried out at the highland semi-arid regions in Piranshahr district (36° 40ʹ N, 45° 08ʹ E; 1840 m). Assessment of phenological development revealed that plants grown under control condition (no-organic and micronutrients fertilizer) had a significantly slower development. Assessment of agronomic characteristics showed that application of micronutrients fertilizer substantially increased plant height, first pod height, canopy width, number of the seed, seed weight, economic and biological yield compared to control condition. By increasing the application rate of organic fertilizer its positive effects became more impressive on growth and yield component. The best growth performance was recorded by integrated application of 40 t ha-1 organic fertilizer and micronutrients fertilizers. However, there was no significant difference between fertilizer of Fe and Zn. Overall, the results indicated that the studied site is facing with micronutrient deficiencies and application organic fertilizer can noticeably improve the efficiency of micronutrients fertilizer. A quick and supplementary approach is therefore required for remedy of both Zn and Fe deficiencies in the short term. The finding showed that a substantial yield improvement is possible by integrated application of organic and micronutrient fertilizer.

The Impact

The experiment was conducted in a greenhouse during 2017 and 2018 growing seasons to evaluate the impact of the shading and various nutrition programs on mitigating heat stress, reducing the use of chemical minerals, improving the reproductive growth and yield of tomato plant. Split-plot within Randomized Complete Block Design (RCBD) with three replications was conducted in this study. Shading factor was allocated in the main plots and the nutrition programs distributed randomly in the subplots. Results indicate that shading resulted in the decrease of daytime temperature by 5.7˚C as an average for both seasons; thus a significant increasing was found in leaf contents of macro nutrients (Nitrogen, Phosphorous, and Potassium), and micro nutrients (Iron, Zinc and Boron), except the Iron content in 2018 growing season. Furthermore, shading improved significantly the reproductive growth and tomato yield. Among the plant nutrition programs, the integrated nutrient management (INM) including the application of organic substances, bio inoculum of AMF and 50% of the recommended dose of chemical fertilizers; lead to the enhancement of nutrients content, reproductive characteristics and plant yield. Generally, combination of both shading and INM showed positive effects on plants nutrient status and persisting balance on tomato flowering growth and fruits yield.

Effects of corn steep liquor (organic fertilizer, OF) and conventional chemical fertilizer (CF) on the growth and yield of bok choy (Brassica rapa var. chinensis) in summer and autumn hydroponic growing systems were compared. When OF and CF were applied with the same amount of total nitrogen in summer cultivation, there was no significant difference between yields; however, the growth rate in OF was slower than in CF. When OF was applied with twice the amount of nitrogen in CF (OF2), bok choy growth and yield were significantly inhibited in summer cultivation, likely owing to dissolved oxygen deficiency and different rates of nitrification and nitrogen absorbance by the plant root. Although the contents of potassium, calcium, and magnesium in bok choy showed no difference among the three treatments in both cultivation seasons, the carbon/nitrogen ratio tended to be higher in OF and OF2 than in CF. Lower nitric acid and higher ascorbic acid content was found in OF and OF2 than in CF. Overall, our results suggest that a comparable yield is expected by using the same nitrogen amount with a conventional recipe of chemical fertilization in autumn cultivation. However, further improvement of hydroponic management is needed in summer cultivation.

<p>ABSTRACT</p><p>Rainfed ricefield, planted at least for one cropping season in a year, depends heavily on rainfall for its water supply. This land generally is low in fertility as indicated by the limited availability of essential plant nutrients in particular nitrogen (N), phosphorus (P), and potassium (K) as well as organic matter. Its productivity is relatively low with a rather erratic precipitation distribution. In order to overcome fertility issue in rainfed land, it is necessary to conduct an integrated nutrient management; one of which is by implementing location specific nutrient management. This study aims to seek the appropriate nutrient management in rainfed paddy field of Semawung village in the sub-district of Andong of Boyolali regency to be provisioned as a technological tool of location specific nutrient management. Research on nutrient management of gogo rancah system-based paddy production was carried out from October 2014 to January 2015. The field experiment was arranged in a Randomized Block Design involving eight treatments and three replications for each treatment. Treatments were combinations of NPK fertilizer, Organofosfat, and straw-based organic fertilizer. Nutrient management using NPK fertilizer and its combination with Organofosfat or organic fertilizer had very significant effect on plant height and number of stem per hill, significantly affected number of panicle per hill, panicle length, and number of fully-filled grain but did not result in difference of fully filled grain percentage and weight of 1000 grains. There was no significant difference between the treatment of 100% of NPK fertilizer and the combination of 75% of NPK fertilizer with straw-based fertilizer regarding these variables: number of stem per hill, number of panicle per hill, panicle length, number of grain per hill, number and percentage of fully-filled grain, weight of 1000 grains, and weight of fresh grain and milled grain yield. Therefore, the latter treatment is feasible as an option of location-specific nutrient management Semawung village.</p>

Trenched beds covered with plastic mulch was used to capture and retain precipitation for dryland cantaloupe production. Two trenches were formed in the fall in raised beds. Plastic mulch was laid over the beds and slitted at ca. 1 meter intervals over the trenches. Soil was placed over the slits, conforming the plastic to the shape of the trenches and channeling precipitation into the beds. Cantaloupes were seeded in the spring and grown with no supplemental irrigation. Planting moisture was significantly greater under the capture system than in unmulched beds. Seedling emergence time was reduced from 18 to 6 days and vine growth in the first 6 weeks was almost doubled. Total and marketable yields were doubled and fruit size significantly increased when water was limiting. Elevated soil temperatures under the mulch enhanced plant growth and yield even when moisture was not limiting. Combining a moisture capture system with supplemental irrigation could allow commercial production of cucurbit crops under limited water conditions in semi-arid areas.

Abstract Acacia nilotica is an important agroforestry specie, which is used in both compact and linear forms. The objective of the current study was to evaluate the effect of compost on the growth performance and biomass production of A. nilotica. Completely randomized design (CRD) was used to analyze the variations among several growth morphological traits. Two parallel trials, pot trial (seedlings), field trial (saplings) were conducted simultaneously. Compost and litter mixture were applied in mentioned trials. Following treatments were used: T0 – control; T1 - 25% of compost and 75% of nursery soil; T2 - mixture of 50% nursery soil and 50% compost; T3 - mixture of 75% compost and 25% of nursery soil; T4 - where 100% compost was applied. Increase in plant growth was observed with the increases in the amount of compost mixture. In field trial maximum plant height, shoot length, root length, rootshoot ratio and biomass production was observed when 100% compost level was applied, while minimum was observed without any compost appli-cation. In pot trials, the maximum plant height, rootshoot ratio and biomass production was recorded when 75% compost level was applied. Overall, Acacia performed better with 100% of compost application in field trail and 75% of compost application in pot trial. The results of this study demonstrated the positive effects of compost on the growth of Acacia. The seedling development was improved considerably with different levels having greater percentage of organic fertilizer and it was concluded that compost improves soil fertility and it should be used as organic fertilizer in farming and forestry practices for improving crop growth and yield.

Liquid organic fertilizer is a technology in fertilizing to facilitate application. This study aims to study the response of three types of caisim plant varieties that are applied liquid organic fertilizer with several levels of concentration. The study was conducted using a Complete Randomized Block Design (RCBD), which was arranged in factorial with three replications. The first factor is three varieties of caisim (V) consisting of three levels, namely: v1 = tosakan variety, v2 = shinta variety, v3 = kumala variety. The second factor is the concentration of organic liquid fertilizer (C) consisting of three levels, namely: c1 = 3 ml / l water, c2 = 6 ml / l, c3 = 9 ml / l. The homogeneity of the research data was tested by Bartlett test and Tuckey tested the data in addictiveness then analyzed with variance and continued with the smallest significant difference test (LSD) at 5% level. The results showed that the use of three types of caisim varieties showed significant differences in the growth and yield of caisim plants as indicated by the plant height, leaf number and shoot-root ratio. The treatment of liquid organic fertilizer concentration showed no significant difference in the growth and yield of caisim plants in all observed variables.

Growing vegetable crops such as lettuce, on Ultisol soil has several obstacles, such as insufficient organic matter and nutrients in the soil. The provision of biochar and POC leri or organic fertilizer from rice washing liquid is expected to be a long-term and sustainable solution. This study was intended to test the addition of biochar to the growing media and the application of leri on lettuce cultivation. This study used a factorial Randomized Block Design (RAK) method. The first factor was the application of biochar to the planting medium (M), which consisted of M1: Ultisol without biochar and M2: Ultisol + 30 g biochar. The second factor was the administration of liquid organic fertilizer (LOF) leri (P), with 5 treatments consisting of P0: without giving LOF leri, P1: giving LOF leri without fermentation once a week, P2: giving LOF leri without fermentation twice a week, P3: giving fermented LOF leri once a week, P4: giving fermented LOF leri twice a week. The results of this study were tested statistically by analysis of variance, with the F test; if there was a significant difference, it was continued with the BNJ test (Honest Significant Difference) at a 0.05 level. The results showed that the best treatment of LOF leri in increasing lettuce growth and yield was 25% fermented LOF leri given 2 times a week, at 250 mL per lettuce plant. As a single treatment the best growing media was M2 (Ultisol soil + 30 g of biochar) with a plant height of 25.80 cm and the leaf number of 12.83; whereas the best LOF leri treatment was P4 (fermented LOF leri given twice a week), with a plant height of 30.27 cm and leaf number of 14.42. Based on whole plant fresh weight, the best treatment was the M2P4 (Ultisol + biochar growing medium and fermented LOF leri given week), which was 185.99 g per plant.

Soil Fertility Status

Soil fertility management in agricultural land is challenging in hilly areas of Nepal. The study assesses the soil fertility status of Bari (upland) and Khet (lowland) agriculture land in Mid-hill of Gorkha district. Altogether 30 samples were collected from soil surface (0 to 20 cm) by using hand shovel in January, 2017. The soil fertility parameters like pH, organic matter (OM), total nitrogen (TN), available phosphorus (P) and available potassium (K) were analyzed using standard methods in the laboratory of Central Department of Environmental Science, Tribhuvan University. Results revealed that an average pH in upland (6.62) was higher than the lowland (5.94). Similarly, OM (3.95%) and K (36.49 kgha-1) were relatively high in upland. In addition, pH, OM and available K were significantly varied at p<0.05 in upland and lowland soils, however, there is no significant difference in TN and available P. In addition, soil nutrient index showed that status of available K in both types of land is low, while OM and TN are medium soil quality in upland and lowland soil. The use of organic fertilizer and improved farming system can maintain and sustain soil fertility for crop growth and yield. Understanding distribution of soil nutrients in the study area might be useful for planners to make effective soil fertilizer management strategies.
