Experiments were conducted during 2017-19 at the Integrated Farming System Research Station, Karamana, Kerala Agricultural University for assessing the impact of quantity of potting media, foliar application of multinutrient mixture IISR Power Mix G and microbial inoculants Arbuscular Mycorrhizal Fungi (AMF) and Trichoderma on the growth, nutrient uptake and yield of ginger variety Karthika grown as pot culture. The study revealed that 12 and 15 kg of potting media filled grow bags could produce comparable yields of ginger significantly higher than that obtained with 9 kg of potting media. Application of IISR Power Mix G @ 0.5% at 2 and 3 months of planting enhanced the yield of ginger to the tune of 11 per cent in comparison to control. Microbial inoculants AMF (5 g plant-1) and Trichoderma (1 kg mixed with 90 kg FYM and 10 kg neem cake and 250 g of the mixture used) applied at planting time followed by Trichoderma at 1 month after planting resulted in higher fresh ginger yield of 596.67 g bag-1 and was comparable to 550 g of fresh ginger obtained with application of AMF and Trichoderma at planting.
An experiment was conducted at water management research unit of Kerala Agricultural University, Thrissur during 2011 and 2012 from June to November to asses the optimum spacing requirement of chilli grown inside greenhouse. Experiment was laid out in Randomized Block Design with four treatments and five replications. Treatments consisted of three spacing viz., 45 × 45 cm, 50 × 50 cm and 55 × 55 cm in the greenhouse condition and it was compared with chilli grown under open field condition with spacing of 45 × 45 cm. Results revealed that chilli performed better under greenhouse condition than under open condition during rainy season. Spacing had significant influence on the growth and yield of chilli under green house condition. Spacing of 50 × 50 cm recorded highest yield followed by 55 × 55 cm.
A coconut-based integrated farming system (IFS) model suited for lowlands was developed at the Integrated Farming System Research Station (IFSRS), Karamana, Kerala State, India, under Kerala Agricultural University. The area of the model was decided as 0.2 ha, matching the average per capita land availability of a marginal farmer in the State. Apart from the major crop coconut, intercrops, such as vegetables, fruit crops, spices, fodder and tuber crops were included in the model. The allied enterprises integrated were livestock, azolla, and agroforestry. Tree components of the model comprised of teak, jack, breadfruit, garcinia and mango. Research data for five years revealed that the model generated food products above the requirement of a four-member family, and the surplus production could contribute to farmer’s income. The productivity under the IFS model was enhanced ten-folds compared to that under the sole crop of coconut for the same area. Plant nutrients were generated within the farm through organic recycling, which contributed to the substantial saving of chemical fertilizers. The system was found climate-smart because of reduced use of chemical fertilizers and net negative emission of greenhouse gases mostly achieved through agroforestry. This IFS model could also ensure considerable employment generation. The model could be adopted by farmers of lowland tracts of Kerala having similar agro-climatic features for better economic returns and environmental benefits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
