Leaf Boron and Potassium and Nut Weight in Coconut (Cocos nucifera L.) as Affected by their Individual and Combined Applications  in Terai Region of West Bengal

Coconut (Cocos nucifera L.) is an important crop in West Bengal, India. The coconut mite, Aceria guerreronis Keifer (Eriophyidae), is becoming a serious threat to its cultivation in that state. This mite lives underneath the perianth, attacking the epidermis and causing damage that leads to considerable yield reduction. The same habitat was found to be shared by several other mites during a one year study in a coconut orchard in South 24 Parganas District ofWest Bengal, in 2007–2008. In total, 11 species of nine families were found in this study, including mites of different feeding habits, but mainly predatory and phytophagous mites. Neoseiulus paspalivorus (De Leon) was the predominant predator, while A. guerreronis was the predominant phytophagous species. Both were found throughout the year. The highest abundance of those species occurred in April and June, respectively. The association of N. paspalivorus and A. guerreronis has been observed in different countries and in other parts of India.

Abstract A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut (Cocos nucifera L.) coir dust (CD) as growing media components for greenhouse production of Dracaena marginata Bak. and Spathiphyllum Schott ‘Petite’. Three soilless foliage plant growing mixes (Cornell, Hybrid, University of Florida #2 [UF-2]) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (% by vol): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2 = 50 CD or SP: 50 PB. Dracaena root growth was not affected by treatments but there were significant mix × media component interactions that affected plant top growth parameters. In general, the growth and quality of D. marginata were reduced by using CD in Cornell, had no effect in Hybrid, and increased in UF-2. S. ‘Petite’ grew equally well in all growing mixes regardless of whether CD or SP was used; however, plants grew more in Cornell and Hybrid than in UF-2. S. ‘Petite’ roots, which were infested with Cylindrocladium spathiphylli, had higher grades when grown in CD than when the media contained SP.

Cocos Nucifera L

Abstract Objectives Lead primarily affects male reproductive functions via hormonal imbalance and morphological damage to the testicular tissue with significant alteration in sperm profile and oxidative markers. Though, different studies have reported that Cocos nucifera L. oil has a wide range of biological effects, this study aimed at investigating the effect of Cocos nucifera L. oil on lead acetate-induced reproductive toxicity in male Wistar rats. Methods Twenty (20) sexually matured male Wistar rats (55–65 days) were randomly distributed into four groups (n=5). Group I (negative control)—distilled water orally for 56 days, Group II (positive control)—5 mg/kg bwt lead acetate intraperitoneally (i.p.) for 14 days, Group III—6.7 mL/kg bwt Cocos nucifera L. oil orally for 56 days and Group IV—lead acetate intraperitoneally (i.p.) for 14 days and Cocos nucifera L. oil for orally for 56 days. Rats were sacrificed by diethyl ether, after which the serum, testis and epididymis were collected and used for semen analysis, biochemical and histological analysis. Results The lead acetate significantly increases (p<0.05) testicular and epididymal malondialdehyde (MDA) levels, while a significant reduction (p<0.05) in sperm parameters, organ weight, testosterone and luteinizing hormone was observed when compared with the negative control. The coadministration of Cocos nucifera oil with lead acetate significantly increases (p<0.05) testosterone, luteinizing hormone, sperm parameters and organ weight, with a significant decrease (p<0.05) in MDA levels compared with positive control. Histological analysis showed that lead acetate distorts testicular cytoarchitecture and germ cell integrity while this was normalized in the cotreated group. Conclusions Cocos nucifera oil attenuates the deleterious effects of lead acetate in male Wistar rats, which could be attributed to its polyphenol content and antioxidant properties.
