Pineapple is a fruit crop that constantly contribute to Malaysian agricultural GDP. Local pineapple industry is dominated by smallholders who are largely ill-equipped with ICT and modern technology. Sarawak as the nation’s second largest producer after Johor, has a substantial yet declining size of agriculture, forestry, and fishing workforce. Therefore, the state needs to capitalise on the increasingly accessible e-agriculture technology and high value crop such as MD2 pineapple (Ananas comosus var. MD2) to optimise yield and workforce. Efficient fertiliser management is essential to ensure sufficient and timely usage of fertiliser and related resources. Therefore, the AnanasApp mobile app is introduced as a tool to boost ICT application in local pineapple industry. AnanasApp that is built for the Android platform, is designed to assist with fertiliser management across all pineapple farming scales by identifying fertiliser requirements and costs per crop cycle, and guiding users to systematic fertilisation application. Equipped with important features such as simplicity, ease of use, user-friendliness, and high level of accessibility, the app can also attract younger pineapple growers and subsequently sustain the industry’s workforce.
A field experiment entitled “Effect of Weed Management Practices on weed control efficiency, yield and economics of transplanted rice was conducted during Kharif 2016 at Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U. P. (India) to find out the impact of different herbicides on weed flora, yield and economics of transplanted Rice (Oryza sativa L.). Among weed management practices sole application of Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE), Pyrazosulfuron (150 g a.i ha-1 PE), Butachlor (1.5 kg a.i ha-1) obtained selectivity towards broad leave weeds, whereas Oxidiargyl (100 g a.i ha-1 PE), Anilophos fb Bispyribac Sodium (400 g a.i ha-1 PE fb 25g a.i ha-1 POE), Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE) performed selectivity towards narrow leave weeds, respectively. Similarly, Pyrazosulfuron fb Azimsulfuron (150 g a.i ha-1PE fb 30 g a.i ha-1 POE) recorded selectivity towards narrow leave weeds. Among weed management practices, this research finding indicates that the application of Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE) proved to be the most effective in minimizing the total weed density (5.0,6.26 and 6.10 m-2), biomass of weed and enhancing the weed control efficiency (74.96 %), grain yield (46.20), net return (47902) and benefit ratio (2.27) which have the potential of being used as best combination of herbicides. Effective weed control practices could be used for the better production of transplanted rice in Typic Ustochrept soil of Uttar Pradesh.
All aspects of plant growth and development are adversely affected by salinity stress. In arid and semi-arid regions, where rainfall is scanty, this detrimental effect on the crop productivity becomes more prominent. Salt stress induced crop losses are likely to increase substantially in the coming decades if appropriate corrective measures are not undertaken to tackle the intertwined menaces of salinity, water logging, and ions toxicities. This study clarifies the effectiveness of Cut-soiler (machine) constructed rice residue filled preferential shallow sub surface drainage (PSSD) to improve the drainage function and consequent effect on growth traits and yield of mustard during 2019-21. The study comprised of Cut-soiler drains as main plot treatment with two soil types (sub-plot) and three irrigation water salinity (4, 8, 12 dS m-1) as sub-sub plot treatment in a double replicated split-split experiment. Cut-soiler PSSD resulted in higher drainage outflow of water and salts with applied irrigation and rainfall events and reduced soil salinity by ~50.36 % without any extra salt loading even with the application of 12 dS m-1 salinity water irrigation. Such reduction in soil ECe, due to Cut-soiler constructed PSSD, led to significant improvement in plant height, number of leaves, branches and plants, leaf weight ratio, leaf area duration, specific leaf area, specific leaf weight, absolute growth rate and dry matter efficiency. These positive changes consequently enhanced mustard biological yield (18.08 %) and dry matter efficiency. All together it was observed that Cut-soiler PSSD effectively reduced the soil salinity even under the application of saline water (upto 12 dS m-1) irrigation.
The growth of the Scenedesmus spinosus microalgae was evaluated in four culture mediums: Z8, Watanabe, Bristol and BG-11, using a pilot airlift tubular photobioreactor. The reactor used had a culture volume of 1.4 m3 and consisted of 4 vertical tubes assembled to 4 horizontal tubes of transparent polycarbonate with PVC joints. Turbidity, total solids, solar irradiation and temperature were measured for a period of 21 days. Biomass growth was evaluated through the change in turbidity over time and gravimetry tests, for the four analyzed culture mediums. The medium that showed the highest biomass growth over time corresponded to the Z8 medium, while the one that showed the lowest growth was the Bristol medium. The highest biomass productivity corresponded to 81 g m-3d-1 for the Z8 culture medium, and the lower was 14 g m-3d-1 for Watanabe.
Lentinula edodes (Berk.) Peglar, the shiitake mushroom, is worldwide one of the most widely cultivated mushrooms. The cultivation of edible mushrooms is a biotechnological process that uses various residues to produce food of high nutritional value. Two strains of Lentinula edodes (DMR-356 and DMR-35) were cultivated on basal substrate wheat straw and poplar sawdust alone and in combination with supplements (Wheat bran, Rice bran and Maize Meal). Complete spawn run, bump formation, basideocarp formation days, total yield and biological efficiency were recorded. Minimum time taken for complete spawn run, bump formation and basideocarp formation was observed on wheat straw + wheat bran (20%) + CaCo3 (2%). Wheat straw + wheat bran (20%) + CaCo3 (2%) produced maximum total yield and biological efficiency in DMR-356 (567.0g/900g of dry substrate) with biological efficiency (63.0%) and DMR-35 (497.6g /900g of dry substrate) with biological efficiency (55.2%). Poplar sawdust substrates alone proved to be least effective for the cultivation of Lentinula edodes strains, with maximum days taken for complete spawn run, Bump formation and basideocarp formation day, while minimum total yield with DMR-356 (114.0g/ 900g of dry substrate) and corresponding lowest biological efficiency (12.6%) and with DMR-35 strain minimum total yield (57.0g/ 900g of dry substrate) and biological efficiency (6.0%) was recorded.
