Root knot nematodes are responsible for severe crop loss in cucurbits to the tune of 547.5 million. Pot culture experiments were conducted under glasshouse conditions to study the effect of ischolar_main knot nematode, Meloidogyne incognita Kofoid and White in twelve wild and cultivated cucurbitaceous species and to identify resistant ischolar_main stocks for grafting in bitter gourd. Second stage juveniles of M. incognita were inoculated at 2J2 per cc soil into the rhizosphere of 21 days old seedlings and changes in the growth rate viz., shoot length, shoot fresh and dry weight, ischolar_main length, ischolar_main fresh and dry weight were recorded after sixty days after inoculation. Number of galls per 10 gram of ischolar_main, egg mass and females per gram of ischolar_main, soil nematode population per 200 cc soil, final nematode population and ischolar_main gall indices were also determined at the end of the experiment. Soil and ischolar_main population of nematodes were assessed by standard methods and growth parameters were worked out. Among ten ischolar_mainstocks screened against M. incognita, three genotypes viz., Kumati kai (Citrulus colocynthus), african horned cucumber (Cucumis metuliferus) and pumpkin (Cucurbita moschata) showed resistant reaction followed by two ischolar_mainstocks viz., Sponge gourd (Luffa cylindrica,/i>) and mithi pakal (Momordica charantia var. muricata) which were moderately resistant. These ischolar_mainstocks were further used for grafting with bitter gourd scion.Keywords

A field experiment to study the soil, plant nutrient status and yield of hybrid chilli (Capsicum annuum L.) CCH1 as influenced by fertigation of N and K fertilizers was carried out during 2010-12. The experiment was laid out in Randomized Block Design with three replications and the treatments included were three levels (125, 100 and 75 % recommended dose) each of water soluble and straight fertilizers. The soil nutrient parameters viz., available soil nitrogen, phosphorus, potassium content and plant nutrient parameters viz., leaf nitrogen, phosphorus and potassium were recorded. The yield parameters like number of fruits per plant, fruit girth, and fruit weight, green fruit yield per plant and per plot were also recorded. The study revealed that the soil and plant nutrient contents in general increased up to 120 days and then declined. Among the several treatments, NPK @ 100 per cent recommended dose of water soluble fertilizers along with liquid biofertilizers registered the highest value for the soil, plant nutrient content and yield parameters.Keywords

An experiment was conducted to find the effect of different levels of nutrients through water soluble fertilizers along with Azophosmet and humic acid on nutrient uptake pattern of hybrid watermelon 'Kiran'. Application of 125 per cent of water soluble fertilizers viz., 250:125:125 kg/ha of NPK in addition to Azophosmet and humic acid showed the best performance in almost all the parameters studied in both seasons I and II, as it recorded the highest nitrogen uptake, phosphorus uptake and potassium uptake by plant and it showed an increasing trend from 30th to 75th DAS invariably in all the treatments during both the seasons studied. Control plots showed un-satisfactory results regarding all the parameters.Keywords

An investigation was carried out to assess the extent of heterosis for fruit, yield and quality parameters in pumpkin (Cucurbita moschata Duch. ex Poir). The trial was conducted at Department of Vegetable Crops, Horticulture College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, during 2009-2010. Hybrids developed by line x tester mating design, with twelve lines and three testers along with commercial check MPH 1 in pumpkin, were evaluated for fruit weight, fruit number per vine, fruit equatorial diameter, fruit polar diameter, flesh thickness, seed number per fruit, seed weight per fruit, fruit yield per vine and quality parameters, viz., total carbohydrate content, total carotenoid and crude fibre content in the fruit. Among the hybrids, Kasi Harit x Avinashi Local showed positive and significant heterosis for fruit number per vine, flesh thickness, seed weight per fruit, total carotenoid content and fruit yield per vine. Vadhala Gundu Local x CO 2 was the next best, as, the hybrid possessed desirable traits, viz., high fruit number per vine, flesh thickness, total carotenoid content and fruit yield per vine.Keywords

An investigation was carried out to study the performance of 36 hybrids of pumpkin (Cucurbita moschata Duch. ex Poir) through Line x Tester mating design. Observations were recorded on the traits, viz., vine length, days to first female flower appearance, node number for first female flower appearance, sex ratio, days to first harvest, fruit number per vine, fruit weight, flesh thickness and fruit yield per vine, besides quality traits such as total carbohydrate content, total carotenoid content and crude fibre content in the fruit. Among the 36 hybrids of pumpkin studied, the cross 'Kasi Harit x Avinashi Local' excelled in yield per vine, followed by the crosses 'Vadhalagundu Local x CO-2' and 'Narendra Uphar x CO-2', respectively. Thus, first generation hybrids can be well-utilized for exploiting hybrid vigour to achieve improved quality.Keywords

To study the combining ability and heterosis for yield and quality characters, full diallel analysis was carried out in bitter gourd during January - April 2008 (Thai pattam), with 10 diversified parents, at Research Farm, Horticultural College and Research Institute, TNAU, Coimbatore. Parental mean and gca effects revealed that the parents Preethi, CO-1, MC-30, Uchha Bolder, Green Long and MC-105 were the best genotypes for improvement of yield, combined with quality characters. Hybrids, viz., Preethi x MC-30, KR x USL, MC-105 x MC-10 and Priyanka x CO-1 registered favourable values for mean, significant sca and standard heterosis for yield and quality parameters. Hence, these hybrids are recommended for commercial exploitation of heterosis. Comparison of parental gca and sca of hybrids revealed that hybridization between good x good, good x poor, medium x poor and poor x good combiners gave rise to hybrids with significant sca effects. Considering the mean performance, sca and standard heterosis, hybrid 'Preethi x MC-30' registered favourable values for the most important characters like earliness, number of fruits, fruit yield and quality. Top performing F1 hybrids can be tested over seasons and locations for assessing stability for high yield and quality.Keywords
