“…The number of days to flowering in both varieties was between 84 and 87 DAS without significant differences between the varieties. In other experiments, blooms were reported from 48-68 days (Anjani et al, 2018) and 47-51 days (Rukshar et al, 2018). The number of days to flowering of eleven varieties in a temperate region of Mexico ranged between 99 and 149 DAS (Solis Bonilla et al, 2016).…”

This study discusses how soil moisture influences the seed yield of two castor plant varieties in an arid zone in Mexico. An experiment was set up with two factors: soil moisture, with three levels (high = -0.05 MPa, medium = -0.31 MPa and low = -0.91 MPa), and castor variety (Krishna and Rincon). The combination resulted in a factorial 3 × 2 experimental design. The experiment was set up as a randomized block with four replications under a split-plot arrangement, where the whole plots were for soil moisture and the subplots were for the castor variety. The measured variables were plant height (PH), days to flowering of 50% of the plants (DF), leaf area (LA), dry weight (DW), source-sink relationship, harvest index (HI) and seed yield. Data were analyzed by ANOVA, mean tests (HSD at α = 0.05) and regression analysis. There were significant differences in PH, LA, DW, HI and yield among the treatments. The values of PH, LA and DW tended to be higher at higher soil moisture levels than at lower moisture levels. The source strength was generally lower than the sink strength in all the treatments. There were significant differences between the varieties for HI, and the interaction between soil moisture and variety was also significant. Significant differences were found in yield; the Krishna variety had a greater yield than the Rincon variety, but there was only a significant difference between the yield of the Krishna variety cultivated under low soil moisture (5200 kg ha -1 ) and that of the Rincon variety cultivated under high soil moisture (2570 kg ha -1 ). The results of this study indicate that castor plants can be cultivated in arid regions at suboptimal soil moisture levels with supplementary irrigation without compromising plant performance or yield.

“…There are hybrids, such as GCH4, that are resistant to the attack by E. flavescens due to the high wax content on the plant stems and leaves (Lakshmi et al 2005). Five accessions viz., RG-43, RG-631, RG-1621, RG-3037 and RG-3067, among 165 core set accessions representing diversity in the entire collection maintained at ICAR-Indian Institute of Oilseeds Research, Hyderabad, India, exhibited resistance reaction against E. flavescens; oil content of these accessions was 46, 51, 51, 51, 52 %, respectively (Anjani et al 2018). On the other hand, Severino et al (2012) recommended parallel research to determine the increased potential susceptibility to pests in breeding programs to develop low-ricin, low-ricinine, and low-allergen cultivars to reduce hazardous chemical products found in R. communis.…”

Interest in bioenergetic crops, such as the castor oil plant Ricinus communis (Euphorbiaceae), for production of biodiesel has increased in recent years. In this paper, phytophagous arthropods, their natural enemies and floral visitors associated with this plant in the world are reviewed. Despite its insecticidal properties, arthropods have been reported feeding on R. communis plants. The arthropod pests of R. communis damage all parts of the plant, including the seeds, where some toxic compounds are even more concentrated. In the scientific databases, we found reports of 193 arthropods associated to R. communis in different parts of the world. This information obtained in the scientific databases was concentrated in a database and analyzed according to the coevolutive hypothesis, which allows us to predict that the greatest wealth and abundance of phytogenic arthropods is found in the center of origin by R. communis. According to this review, Achaea janata, Spodoptera litura, Edwardsiana flavescens, Liriomyza trifolii, L. sativae, Spilosoma obliqua, Cogenethes punctiferalis, Oxyrhachis taranda, and Helicoverpa armigera are the most devastating pests in Asia. In Africa, Agrotis ipsilon, S. exigua, Nezara viridula, Trialeurodes ricini, and Tetranychus urticae were mentioned as the most important. In Central and South-America, Phyllophaga sp., Agrietes sp., Erinnyis ello, N. viridula, Corythucha gossypii, Falconia antioquiana, and S. marima are reported as pests of economic importance. The most commonly reported natural enemies of some of these arthropod pests were species of Bacillus thuringiensis, B. cereus, B. popilliae, Trichogramma achaeae, T. chilonis, T. minutum, T. australicum, T. dendrolimi, T. pretiosum, T. evanescens, Microplitis rufiventris, M. maculipennis, M. ophiusae, Telenomus remus, T. proditor, Stethorus siphonulus and S. histrio. Apis mellifera is recorded as the main insect pollinator of R. communis. Pest management methods used against the arthropod pests of R. communis include biological, ethological, mechanical, cultural, genetic, and chemical control.

“…Anjani et al, stated that although insecticide application is effective in controlling leafhoppers, the length of effective protection varies with an additional requirement of foliar insecticide sprays to control the pest, which eventually increases the cost of production [52].…”

“…Identification and use of resistant genotypes in breeding programme for the development of resistant varieties against the insect pests and their use in IPM (Integrated Pest Management) programmes is the most economical approach and would be inexpensive in long run because it minimizes the number of insecticides application, lessens the expenses involved in plant protection and conserves the natural enemies besides preserving the environmental safety [32]. Host-plant resistance is the most reliable, economical and eco-friendly measure to control leafhopper [52]. Seventeen Indian collections have been identified as stable sources of resistance against leafhopper [38,59].…”
