Abstract

Lime application and integrated nutrient management is often recommended to increase the crop productivity on acidic soils. To ascertain the individual and synergistic effects of lime, NPK and farm yard manure (FYM) application on ground nut productivity, a field experiment was undertaken on acid soils of west Tripura. Application of recommended dose of NPK (20:60:42 kg/ha of NPK) along with lime (10 % of actual LR was followed) resulted in 153 per cent yield increase over control whereas, FYM@ 5 ton/ha along with combined application of lime with recommended NPK boosted the yield improvement upto 210 per cent over control (Farmers' practice). Results of this study suggest that liming along with integrated nutrient management practices, if adopted properly, can lead to more than two-fold increase in ground nut productivity on acidic soils of West Tripura and other districts of the states of Tripura with similar soils. Post harvest soil analysis also showed improved status of organic C, N and P in treated plots, but available K status declined emphasising the need for close monitoring and appropriate K application in such soils.

Abstract

An experiment was conducted at West Tripura district to evaluate the soil properties and nutrient availability as influenced by cultivation of green manuring crop in acidic soil condition of West Tripura district. Soil samples were collected randomly in the fields for analysis of nutrients and organic carbon and other physical properties. The study revealed that the change in soil physical properties and nutrient availability was significantly increased under the green manuring practice. The green manuring crop dhaincha and mung bean was grown on the plots and it was incorporated into the soil by ploughing before attaining the flowering stage. Further the land was left for 24 days for decomposition of green manure. Highest grain yield of paddy (5.5 t/ha) was observed in dhaincha- aman paddy- potato cropping system whereas the lowest grain yield of paddy (3.5 t/ha) was obtained in fallow- aman paddy-potato cropping system. The grain yield obtained from mung bean- aman paddy- potato cropping system was 4.8 t/ha.

Abstract

Maintenance or enhancement of soil quality is important for sustainable agricultural production. A field experiment was conducted in farmers fields of North Kamalnagar village of Teliamura sub-division of Khowai district. Surface soil samples were collected from the fields of farmers treated with vermicompost @ 2.5 tonnes per ha along with recommended dose of NPK taking cabbage as test crop. Comparison was made with control plot where no treatment was made. Mean values of organic carbon (OC) and available NPK were found higher in the treated fields which were low in control. In vermicompost treated soils the yield and weight per head of cabbage was found higher as compared to control plot.
