An experiment was conducted in farmer’s field at different locations of kole lands to study the effect of micro nutrient Boron on yield and soil nutrient status of rice during 2012-2014. The treatments comprised of different levels of B viz; 2.5 kg Borax/ ha, 5 kg Borax/ha, 10 kg Borax/ha, 12.5 kg Borax/ha, 15 kg Borax/ha and untreated control. Observations on growth characters, yield attributes, yield and soil and plant nutrient status were recorded. The application of 15 kg borax /ha recorded the maximum number of panicles/m2 , number of grains /panicles, thousand grain weight, grain and straw yield of rice. The results of pooled data on plant and soil nutrient status revealed that application of boron had a positive effect on uptake and availability of nutrients in soil. The study concluded that the soil application of borax@ 15 kg /ha was found to be good for correcting the deficiency in B deficient areas of Kole lands.

A field experiment was conducted to explore the effects of organic manures and green manuring practices on growth, yield attributes, quality and economics of lemongrass (Cymbopogon flexuosus L.) under custard apple (Annona squamosa L.) based agri-horti system. The findings indicated that growth, yield attributes and yield as well as oil composition, soil nutrient status, microbial populations were significantly increased due to the use of both organic manures and green manuring. The significantly higher results were obtained with vermicompost (2.5 t/ha) + Azotobacter, which was found superior over other practices in terms of growth, yield attributes, oil composition and its quality and soil nutrient status as well as economics of crop cultivation.

The field experiments were conducted in farmer's field at five locations each of kole lands to study the effect of Magnesium (Mg) on yield and soil and plant nutrient status of rice during 2012-2013 and 2013-2014. The experiment was laid out in randomized block design with three replications. The treatments comprised of different levels of Mg viz; 40, 60, 80, 100, and 120 kg Magnesium sulphate(MgSO4)/ha along with control. Observations on growth characters yield attributes, yield and soil and plant nutrient status were recorded. The results revealed that application of 100 kg MgSO4 / ha recorded the maximum number of panicles/m2 (419.13), number of grains/panicle (109.36), thousand grain weight (28.78 g), grain (9.27 t/ha) and straw yield (9.04 t/ha) of rice. The results of pooled data on plant and soil nutrient status revealed that application of magnesium had a positive effect on nutrient content and availability of nutrients in soil. A significant positive correlation was also noticed between Mg application, yield attributes, yield and nutrient contents. The study concluded that application of 100 kg MgSO4 / ha was found to be optimum for correcting the deficiency in Mg deficient areas of kole lands under below sea level farming.

Specific Location

The area of paddy fields in Malinau Kota District is around 463 ha or 10.29 percent of the productive paddy in Malinau Regency which reaches 4,500 ha. The productivity of rice in the area is still low, which is around 3-4 ton ha-1, its caused by the use of fertilizers that are not yet suitable for plant growth requirement. Therefore, in order to improve rice productivity, it is necessary to do soil analysis to formulate spesific location fertilizer recommendations based on soil nutrient status. The assessment was carried out in Malinau District, Malinau Regency, on September-November 2017. The purpose of the asseement was to develop recommendations for fertilizing specific location lowland rice based on soil nutrient status. The assessment method is to take composite soil samples from several representative locations, then analyze in the laboratory, and the results of the analysis are used to formulate recommendations for specific location lowland rice fertilization. The results of soil analysis showed that soil pH was acid, organic C-content was low, N-tot was low, P was medium and K was medium. Recommendations of N fertilization with Urea as the basic fertilizer 50-100 kg ha-1 and subsequent N fertilization based on leaf color chart (LCC), P fertilization with SP-36 as much as 100 kg ha-1, and K fertilization with KCl as much as 50 kg ha-1.

Birbhum District

A GPS based soil sampling and testing was done in 10 blocks of Birbhum district under monitoring of Rathindra Krishi Vigyan Kendra, Birbhum during 2018 and 2019. In this regard, some soil chemical properties were analysed through Mridaparikshak (soil testing kit). After statistical analysis, pooled data of different soil nutrients were compared based on GPS to prepare a data base for easy fertiliser recommendation of different crops without soil testing. It was found that soil pH (6.29 to 5.50), soil O.C (0.77 to 0.31%), available K (292.12 to 226.60 kg/ha), available B (0.81 to 0.17 mg/kg)  and available Fe (44.4 to 21.5 mg/kg) had been decreased with the increase in latitude from 23°04' 07.4500" to 24°11' 15.3400" and longitude. Recommendation of more liming, organic manure, K, B may be done accordingly. On the other hand, available N (184.0 to 296.95 kg/ha), available P (15.05 to 62.76 kg/ha), available S (11.43 to 44.52 kg/ha) and available Zn (0.20 to 1.04 mg/kg) showed sharp direct relation with the increase in Latitude as supported by higher CV value.

SUMMARYMost cocoa farms in Ghana are cultivated in complex agroforest systems, with plant growth and cocoa productivity being affected. The objective of this study was to investigate how shade trees affect cocoa yield, temperature and soil nutrients in low-input cocoa systems. Establishing plots on 24 farms in four locations (districts) in Ghana, we assessed the influence of varying canopy cover and fertilization on cocoa yields. Results showed no relationship between canopy cover and cocoa yields in the light crop season (February to August). For the main crop season (September to January), there was an interaction between shade and yields: Yields were higher on no-shade plots than on shaded plots in two districts, whilst there were no differences at the two other districts possibly due to differences in precipitation and soil nutrient status. On the other hand, there was a positive effect of increased canopy cover on yields within the shaded plots. Soil nutrient analyses revealed no significant differences between shaded and no-shade plots and adequate levels of N, K+, Fe2+, Cu2+ and Zn2+ were recorded. However, soil contents of P, C, Mg2+ and Ca2+ were below recommended values. Peak temperatures recorded in the cocoa canopies were above the recommended range for this species. Although shade trees had a slight modifying effect on peak temperatures, the magnitude appeared too small to have any practical effects.

The uptake of nutrients by the paddy crop better indicative of the fertility, productivity, and plant nutrient status. The main objective of this investigation was that the rate of nutrient application can influence the removal of nutrients into formsavailable to the soil with different landraces in conjunction with the application of different microbial inoculants under different fertility levels. The yield of landraces was significantly influenced by the microbial inoculants under different fertility levels.Significantly higher uptake of N, P and K was observed in the landrace padmarekha compared to other landraces. The nutrient removal from the soil was in the range of 81.57 – 104.08 kg N, 19.55 -33.96 kg P and 88.15 – 111.81 kg/ha Kamong landraces. Similarly, the higher uptake was seen with the application of 100 per centRDF along with the azospirullum, Bacillus megatherium var. Phosphoticum Frateuria quaratia,Thiobacillus thiooxidans and Vesicular ArbescularMycorrizae.The nutrient removal was in the range of 47.11-122.0 kg N, 10.71-36.7 kg P2O5 and 34.22- 141.21 kg/ha K2O among fertility levels in different paddy landraces used in the study. The different microbial inoculants application with the recommended dose of fertilizers in different levels helped in the acquisition of the nutrients from the soil solution illustrating the effects of microbial applications through the increased supply of biologically fixed nitrogen, mobilizing the phosphorus towards plant roots, and potassium availability to the crop. Thus, our investigations acclaim that there is a need to inoculate the crop with different microbial inoculants to increase the use and uptake of the nutrients by the crop and improvement in soil nutrient status.
