Climatic variations have created many challenges for farmers, but the most important one is the change in the dynamics of nutrient uptake by plants. Nutrients that were sufficient in soil are now found deficient, an issue that needs more focus in order to sustain crop productivity. Magnesium is very important plant nutrient that has a direct role in chlorophyll synthesis and interacts with other nutrients to manage physiological mechanisms. We designed field experiments focusing on the foliar application of magnesium at different growth and reproductive stages of a rice crop. Results reveal that the combination of rice cultivation system and magnesium application, i.e., flooded rice with Mg application at seedling + tillering + panicle initiation (F6T2), significantly improved crop growth and exhibited noticeable results in crop yield and grain quality. Moreover, the rice crop also recorded the highest benefit cost ratio (BCR) when kept flooded and fertilized with Mg at three stages; viz seedling, tillering, and panicle initiation; during both the years. Combined application of magnesium at growth and reproductive stages improved crop performance both in aerobic as well as in flooded rice, but the crop grown under flooded condition showed accelerated performance in both cropping seasons, which reflects its viability and economic feasibility.

Background: Study has been undertaken in SAT (Semi-arid tropics) region located between 23o 8'- 26o 30' latitude and 78o11'- 81o30' longitude with an altitude varying from 230 to 280 m above mean sea level (MSL), Central India for assessing the impact after interventions of natural resource management (NRM) under watershed development programme. Agricultural productivity of Semi-arid tropics oscillates between 0.5 and 2.0 ton ha-1 with an average of one ton per ha (Rockstrom et al., 2010; Wani et al., 2011a, 2011b). The main objectives of this study are to establish agroforestry based crop cultivation which provides nutritional food as well as transform the mankind’s living status and also supports the doubling farmer’s income goal without associated ecological harm. Methods: To evaluate the economic feasibility and crop productivity along with agroforestry was worked out on the basis of survey and sampling. To get uniform samples of crops from cultivated fields some specific area selected (1 m x 1 m size) and get about 80 crop samples for measurements from whole watershed. All data has been collected through survey of 40% households of watershed and then all these data subjected to statistical analysis in the laboratory. To minimize the problem and rejuvenate the water body, water resource development plan helps in identify the available sources so that appropriate and effective with durable solutions can be formulated. The net return of crop cultivated was calculated by subtracting the cost of cultivation incurred from sowing to harvesting, for each crop from the gross return and then benefit-cost ratio was estimated for further improvement or scaled up and livelihood security of former. Result: The study has revealed that after watershed interventions and agroforestry based Crop cultivation, water level increased 2-6 m, crop production increased by 45-47%, cropping intensity increased 97-98% from 44-46% and migration decreased by 70-72%. During both season, the expenses on irrigation and labour will decrease, crop productivity will improve and benefit-cost ratio increased. Nutrition based food production provided the base for food security as it is a key determination of food availability.

The experiment was conducted at multilocation testing (MLT) site, Sujanagar, Pabna during the year of 2003-2004 to find out a soil test based economically viable fertilizer recommendation for the cropping pattern Boro-T. aman. Six treatments viz., moderate yield goal (MYG), high yield goal (HYG), integrated plant nutrient system (IPNS), recommended fertilizer of FRG' 97 (BARC) guide (RF), farmers' practice (FP), and absolute control were employed for the study. The grain yield of Boro and T. aman rice increased 18 and 14%, respectively, by IPNS compared to farmers' practice. Total grain yield of rice was increased by about 16% in the IPNS fertilizer package compared to farmers' practice. Fertilizer nutrients supplied both from organic and inorganic sources in adequate amount have a positive effect on productivity of soil. On an average it was found that highest grain yields of Boro rice (5.37 t/ha) and T. aman (4.49 t/ha) were obtained from integrated plant nutrient system (IPNS) where farmers’ practice gave yield of 4.55 and 3.94 t/ha. The highest average gross margin (70385 Tk./ha) and marginal benefit cost ratio (3.78) was also obtained from IPNS plots. Keywords: Crop productivity; fertilizer management; cropping pattern.

Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

Abstract In the quest to promote bamboo agroforestry in the dry semi-deciduous forest zone of Ghana, we evaluated changes in soil properties, crop productivity and the economic potential of a bamboo-based intercropping system. The intercropping system was established from 3-months old sympodial bamboo (Bambusa balcooa) seedlings planted at a 5 m × 5 m spacing and intercropped with maize, cassava or cowpea. Separate monocropping fields for maize, cassava, cowpea and bamboo were set up adjacent to the intercropped field. In both the intercropping and monocropping fields, plots were with fertilizer treatments and without. The experiment was laid out in a split plot design with four replicates and studied over three years. Economic analysis was conducted using the financial benefit–cost ratio method. The results showed that regardless of fertilizer treatments, bamboo agroforestry and monocropped fields had comparable effects on soil properties and crop productivity within two years of establishment. In the third year, however, bamboo agroforestry had significantly (p < 0.05) higher soil moisture, pH and crop productivity levels. An intercropping advantage over monocropping was evident for all crops with respective partial land equivalent ratios for fertilized and non-fertilized intercropped systems as follows: cowpea (1.37 and 1.54), maize (1.38 and 1.36), and cassava (1.12 and 1.19). The economic evaluation also indicated marginal profitability of bamboo intercropping over monocropping systems. From the results obtained, there are clear indications that where bamboo is a prioritized woody perennial, integrated systems with crops may be encouraged.

Abstract : Based on data from the Central Statistics Agency (BPS) of Bali in 2013, the population density in the Metropolitan area SARBAGITA (Denpasar-Badung-Gianyar-Tabanan) was 1.057 inhabitants/km2 with an area of 1.753,63 km2 and population was 1.853.017 inhabitants. Availability of facilities and adequate transportation infrastructure is needed, but in fact the performance of roads in the city center has declined. It is characterized by an increase in travel delay problem. Traffic delay problems in the City of Denpasar commonly occur on the stretch of Gatot Subroto street. To minimize the existing problems, Denpasar City Government plans to develop an underpass at the intersection of Gatot Subroto street and Ahmad Yani street. The aim of this study was to analyze the direct benefits of underpass for road users, to analyze the costs necessary to realize and operate the underpass, and to analyze the economic feasibility of the underpass development investment. Based on primary data and secondary data were obtained from government agencies, the method of analysis in this study used the technique of Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR). Economic analysis conducted in this study used three criteria (NPV, BCR and IRR) with three interest rates (12%, 15% and 18% per year) stating that the construction of an underpass was economically feasible. For example in the second scenario where the interest rate 15% gain on the analysis of value NPV, BCR and IRR respectively is Rp. 233.462.340.102,00; 1,948 and 30,81%. Suggestions can be submitted from this research is the need to contemplate the effect of changes in land use in areas close to the area around the underpass and needed further study that takes into account the needs of additional traffic lanes.

To increase the area, production and productivity of sugarcane and legumes/oilseeds for increasing the profit of the farmers’, field experiments were conducted at Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Karnal during 2005-06 and 2006-07 followed by demonstrations on intercropping of legumes/oilseed with sugarcane at farmers’ field in Kaithal district during 2009-10 and 2010-11. Cane yield did not reduce significantly due to intercropping except raya during 2005-06. The percent incidence of pink borer, shoot borer, top borer and root borer remained below economical threshold level (ETL). In all intercropping systems, total land equivalent ratio (LERt) was greater than unity, indicated yield advantage for the intercropped plots. Land equivalent coefficient (LEC) followed the same pattern as LERt. Total area time equivalent ratio (ATERt) values showed an advantage (22-28 %) with all intercropping systems than sole cropping with maximum advantage from sugarcane + chickpea. Sugarcane was more competitive than pea and lentil intercrops, whereas, raya and chickpea were more competitive than sugarcane. Higher competitive ratio values for the intercrops (CRi) indicated that all the intercrops were more competitive than sugarcane. Total values of actual yield loss (AYL) showed an advantage of 22-38% from intercropping compared to sole cropping. Highest monetary advantage index (MAI) value was obtained from sugarcane + pea intercropping system (75779). However, the minimum MAI was obtained from sugarcane + lentil intercropping system (62382). Demonstrations on intercropping at farmers’ field also resulted in higher gross returns, returns over variable cost and benefit: cost ratio.

Field experiment was conducted during rice fallow season (January-March), 2011 and 2012 to study the effect of DAP application to preceding rice in last irrigation and foliar nutrition to black gram on the productivity and profitability of black gram(ADT 3) under rice fallow condition. The results indicated that application of DAP at 50 kg/ha to preceding rice in last irrigation and foliar spray of DAP (2 per cent) and KCl (1 per cent) at 30 and 45 days after sowing to black gram registered higher plant height (24.6 cm) at 20 DOS number of pods per plant (18.4), grain yield (639 kg/ha), net returns (Rs.22290/ha) and additional income (Rs. 7563/ha). Application of DAP at 50 kg/ha in last irrigation to preceding rice produced significantly higher grain yield of succeeding black gram (613 kg/ha.) over control (488 kg/ha) which was comparable with foliar application of 2 per cent DAP and 1 per cent KCl to black gram. With reference to return per rupee invested, application of DAP at 50 kg/ha to preceding rice in last irrigation registered higher benefit cost ratio of 3.56 in black gram.

Field experiments were conducted during summer (April to June), 2010 and 2011 to study the effect of post-emergence herbicides in irrigated blackgram (ADT 5). Treatments comprising of three levels (50, 75 and 100 g /ha) of the post- emergence herbicides viz., Imazethapyr 10% SL and Quizalofop ethyl 5% EC were tested alone and in combination and compared with hand weeding twice on 15 and 30 DAS(farmers’ practice). Herbicides were sprayed on 15 DAS when the weeds were 2-4 leaves stage using flat-fan nozzle as per treatment schedule. The results revealed that minimum total weed density (8.44) and weed dry weight ( 27.2 g/m2) and higher weed control efficiency (84.4%) were obtained under combined application of imazethapyr and quizalofop ethyl as tank mix at 100 g /ha. However, this was comparable with application of both the herbicides at 75g /ha. Application of imazethapyr + quizalofop ethyl each at 75 g/ha registered significantly taller plants, higher dry matter production, more number of pods per plant, seeds per pod and higher grain yield (826 kg/ha), net returns (Rs.26621/ha) and benefit cost ratio (2.76). Thus, application of post- emergence herbicides imazethapyr + quizalofop ethyl each at 75 g /ha as tank mix on 15 DAS could be recommended for controlling of emerged weeds in irrigated blackgram.
