Item Fruit rot of bitter gourd(Kerala Agricultural University, 1980) Sukumara Varma, A; Abi Cheeran; Peethambaran, C KItem Extraction pattern of soil moisture by bittergourd (Momordica charantia L.) under varying irrigation levels(Kerala Agricultural University, 1990) George Thomas, C; Pillai, G RItem Consumptive use, pattern of soil moisture extraction and water use efficiency of bittergourd (Momordica Charantia L.) under varying irrigation and nitrogen levels(Kerala Agricultural University, 1993) Manorama Thampatti, K C; Santha Kumari, G; Reena Mathew; Chandrasekharan, PThe influence of graded doses of nitrogen and varying levels of irrigation on consumptive use of water, paltern of soil moisture extraction, water use efficiency and f r u i t yield of biltergourd were evaluated during 1988-89 and 1989-90. The consumptive use of water and lit/Eo values of bittergourd increased progressively with levels of nitrogen and irrigation. At higher moisture regimes the variation in consumptive use and Ht/Eo values did not reflect in crop yield. Wale ruse efficiency of the crop maintained a positive relation with levels of nitrogen and a negative relation with levels of irrigation. The soil moisture extraction paltern was not influenced by nitrogen levels. Major part of water was extracted from upper layers of soil irrespective of treatments.Item Yield, quality and shelf life of bittergourd (Momordica Charantia Linn.) fruits as influenced by plant growth regulators(Kerala Agricultural University, 1994) Veenakumari, D; Raju, V K; Devadas, V SEffect of pre-harvest application of GA (200 and 300 ppm), CCC (250 and 500 ppm) and MH (500 and 1000 ppm) as compared to a no-spray control, on growth, quality components and storage life of hittergourd fruits of MC 84 was studied during 1992. The chemicals were applied twice; 10 days after the first fruit set and 15 days after the first application. GA at 300 ppm produced the highest yield, length and girth of fruits which was followed by GA 200 ppm. Moisture content was maximum in fruits obtained from plants treated with CCC at 250 ppm, whereas the highest ascorbic acid content was in fruits of GA (200 ppm) treated plants. Maximum shelf-life of fruits was observed with MH (500 ppm) spray.Item Typhlocybine leafhopper on bittergourd(Kerala Agricultural University, 1996) Maicykutty P MathewItem Heliothis armigera, a new pest of bittergourd(Kerala Agricultural University, 1996) Maicykutty P Mathew; Sheela Paul, T; Ramachandran Nair, S; Madhu, S
