| Summary, etc. | A study entitled ‘Site specific nutrient management for bitter gourd<br/>(Momordica charantia L.) was conducted in College of Agriculture, Vellayani<br/>during 2007-12 with the objective of formulating a site specific nutrient<br/>recommendation for enhancing the bitter gourd production in Kalliyur village of<br/>Kerala. The experiment set up included three steps namely Omission trial, SSNM<br/>field study and validation of results. All the experiments were conducted in farmer’s<br/>fields of Kalliyur village. Kalliyur village, located in Thiruvananthapuram district<br/>with an area of 17.23 km<br/>2<br/> is one of the major vegetable growing tracts and bitter<br/>gourd is a popular vegetable in the locality. Spatial variability studies conducted<br/>revealed that remarkable variations existed in the soil properties across the village.<br/>Data on irrigation water analysis showed that the water used for irrigation was<br/>slightly acidic but safe for irrigation as it did not contain significant amount of<br/>soluble salts and other elements. <br/>Nutrient omission trial conducted in a farmer’s field at selected location<br/>showed that the indigenous supply of major nutrients in the locality is limited. The<br/>growth and yield parameters were the highest in (+) NPK treatment. Though the<br/>highest yield was recorded in (+) NPK plots, yield reduction in P omission plot was<br/>less compared to N and K omission owing to the higher supply of indigenous P in<br/>soil. The SSNM experiment revealed that site specific nutrient recommendations for<br/>high yield target with soil application of micronutrients recorded the highest values<br/>for all the growth and yield attributes of bitter gourd. Nutrient uptake and harvest <br/>index were also the highest in this treatment. The lowest value of harvest index was<br/>recorded by absolute control. In the case of nutrient balance sheet the highest value<br/>of N and K balance sheet was obtained in site specific nutrient recommendations for<br/>high yield target with soil application of micronutrients while the highest value of P<br/>balance sheet was obtained in farmer’s practice II. The correlation study revealed<br/>that bitter gourd yield was highly correlated with nutrient uptake as well as dry<br/>matter production and harvest index. Economic analysis showed that the SSNM<br/>practice is beneficial to farmers as it is able to provide more income than the usual farmer’s practice. The validation trial of the best treatments SSNM treatments with<br/>high yield target showed that the yield increase was consistent and hence can be<br/>prescribed to other farmers in Kalliyur village. <br/>The study thus conclusively proved that the present rates of fertiliser<br/>recommendation are not at all sufficient for getting maximum yield and profit to<br/>farmers. A site-specific nutrient prescription of 123: 59: 160: 30: 40: 25: 10 kg N P<br/>K Ca Mg Zn B ha<br/>-1<br/> was found to produce 24 t of fruits ha<br/>-1<br/> and a dose of 123: 59:<br/>160: 30: 40 kg N P K Ca Mg + 1 per cent Zn foliar + 0.5 per cent B foliar ha<br/> were<br/>found to yield 22 t fruits ha<br/>-1<br/>. The farmers in the area could get a monetary benefit<br/>of<br/> 601604/- and 542104/- ha<br/>-1<br/> respectively by adopting these recommendations.<br/>Adoption of SSNM prescriptions is advantageous not only from the point of view of<br/>increasing profitability to farmers but also minimizing environmental degradation. <br/> |
