A field experiment was conducted at Horticultural Research Station (AICRP on Palms), Kahikuchi of Assam Agricultural University for three consecutive years (2018-20) to study the initial performance of cocoa clones as intercrop in adult coconut (Cocos nucifera L) garden spaced at 7.5 m × 7.5 m taking sixteen cocoa clones. Data on tree height, stem girth, number of pods, pod weight, number of beans pod-1, dry bean weight tree-1 year-1 and single dry bean weight revealed significant variations among the 16 cocoa clones. Dried beans are the prime economic produce of cocoa, and single dry bean weight ranged from 0.95 to 1.4 g. With respect to dry bean yield tree-1, VTLC-20 recorded a significantly higher dry bean yield of 2.2 kg tree-1 followed by VTLC-18 (1.5 kg tree-1) compared to other cocoa clones, and eight clones yielded more than 1.0 kg dry bean tree-1. Results showed that the number of leaves on the crown, number of inflorescences per palm and nut yield of coconut was not negatively affected; rather, there was an increase in the yield of coconut over a period.

The coconut is known as Kalpa Vriksa to the world for being its multi faceted uses, which provide livelihood security to millions of people. Every part of it useful to humans in one of the other ways. The coconut palm is grown in more than 93 countries of the tropics. Its botanical name is Cocos-Nucifera L. and belongs to the aracaceae (Palm) family. The climbing methods of coconuts like manual, mechanical and climbing by Tractor Operated Hydraulic Elevator (TOME) were studied. The stability, safety, harvesting efficiency, drudgery of coconut harvesting is reduced by Tractor Mounted and Self Propelled Coconut Climber (TMSPCC) developed by considering the drawbacks of the above methods. The testing of developed TMSPCC was carried out at a Coconut Research Station, Bhyte Ratnagiri, India. To assess the physiological cost and the drudgery involved in the traditional method of tree climbing operation. The digital polar hart rate meter RS400TM having infrared connectivity sensor was used for recording the heart rates. The technical assessments included the use of biomechanical models, ODR, BPDS. The ergonomical evaluation of TMSPCC was carried out for testing feasibility, ease of operation; workers jeopardize safety health and efficiency for coconut harvesting. Ergonomically operational safe and controlled heart rates are recorded. The fourteen to seventeen number of coconut orchards were harvested in one hour by using TMSPCC. The tractor mounted and self propelled coconut climber founds suitable for harvesting 100 to 120 coconut trees in a day. The net coconut harvesting by using TMSPCC are 4000 coconuts/day. Also TMSPCC is safe, less hazardous and economical as compared to manual climbing coconut harvesting and climbing by the existing tractor mounted hydraulic elevator.

Aims: This study aims to identify the best surface sterilization and evaluate the effect of haustorium suppression on in vitro germination of coconut palm (Cocos nucifera L.) zygotic embryos. Study Design: Survival rate and contamination rate of zygotic embryos after different surface sterilization treatments, regeneration rate and organogenesis through the number of leaves and the length of shoots after haustorium suppression were determined. For data processing, the Analysis of Variance was used to compare the means which were separated according to Tukey test            (P = 0.05). Place and Duration of Study: Coconut fruits (hybrid PB121) were collected 12 to 14 months after controlled pollination from CRAPP (Centre de Recherches Agricoles Plantes Pérennes), station of Sèmè-kpodji in Benin. Experiments were done in Central Laboratory of Plant Biotechnology and Plant Improvement, University of Abomey-Calavi and conducted from june to december in 2019. Methodology: For the zygotic embryos surface sterilization, four treatments combining three concentrations (3%, 6% and 15%) of commercial bleach (Javel la Croix© containing 12° active chlorine) and immersion durations (5 min, 10 min and 20 min) were tested and the survival rate were determined for each treatment after two months culture. The zygotic embryos were then divided in two sets (haustorium excised embryos set and the whole embryos set) and cultured in modified Y3 medium supplemented with 7 g L-1 agar, 2.5 g L-1 activated charcoal, 5% sucrose,  6.10-3 mM 2.4 D (2.4-dichlorophonoxyacetic acid), gibberellic acid and 0.3 mM BAP(6-benzylaminopurine). After five months culture, the regeneration rate, the number of leaves and the length of shouts were recorded. Results: The high survival rate (80%) was obtained with 6% of bleach and 20 min for the immersion duration without pre-disinfection. The suppression of haustorium have significantly increased the number of leaves (4.3 ± 0.02) and the length of shoots (16.2 ±0.7cm) compared to the whole zygotic embryos. Conclusion: This protocol can help to ensure better surface sterilization of zygotic embryos before their in vitro culture and the development of vigorous plantlets in order to improve the slow growth of plantlets, when transferred to the greenhouse or field.

Field experiment was carried out at All India Coordinated Research Project on Palms, Regional Coconut Research Station, Bhatye (DBSKKV, Dapoli), Maharashtra, (India) during the period of 2004-2016 to assess the carbon sequestration and productivity potential of twelve coconut hybrids and three varieties which was laid out in a randomized block design with three replications. Results showed that the two hybrids viz, GBGD x ECT (127.6 nuts/palm/year) and COD x LCT (108.0 nuts/palm/year) are superior with respect to nut production followed by WCT x MYD (107.6 nuts), ECT x GBGD (106.9 nuts) and the standard variety ‘Pratap’. Furthermore, the coconut orchard substantially contributed towards improving the above and below ground carbon stock. The above ground standing biomass and carbon stock recorded was the highest in the variety East Coast Tall (312 kg/plant and 27.32 t/ha, respectively) followed by hybrid WCT x GBGD (308.69 kg/plant and 27.01 t/ha, respectively) and the lowest was in hybrid MYD x ECT (138.71 kg/plant and 12.14 t/ha, respectively). The highest soil carbon stock 39.12 t/ha and 37.16 t/ha at 0-30 and 31-60 cm depth was recorded in the rhizosphere of hybrid ECT x MYD and the lowest soil carbon stock (35.52 t/ha and 34.71 t/ha) was observed in hybrid PHOT x GBGD.

A comparison is made on the effect of organic and inorganic fertilizers on the some morphological characters of coconut. The study demonstrated that the treatments T1 {Nitrogen, Phosphorus and Muriate of potash (NPK) + Neem seed powder (NSP) + Gliricidiasepium leaves (GSL)} and T2 (NPK+ GSL) significantly increased most of the morphological characters (stem girth, number of leaves, petiole and leaflets). The study revealed that vegetatively the coconut was grown well on soil amended with organic and inorganic fertilizers. The morphological characters i.e the stem girth (173.77 cm) of coconut at 20 cm height T1 (NPK + NSP + GSL) treatment produced maximum girth as compared to T2 to T8 {T2 (NPK+ NSP), T3 (NPK+ GSL), T4 (NSP + GSL), T5 (NPK), T6 (GSL), T7 (NSP), T8 (Control)} treatments. The 11 leaf scars length (80.44 cm) was significantly (p<0.05) highest in T1 as compared to T3 to T8 treatments. The present study also revealed that the number of leaves (28.77) were significantly (p<0.05) greater in T1 as compared to T5 to T8 treatments. The petiole length (139.44 cm) and thickness (3.27 cm), were found significantly (p<0.05) highest in T1 as compared to T8 treatment. Leaflets length and number of leaflets were significantly high in T1 and T2 as compared to T3 to T8 treatments while, the leaflets width (5.04 cm) was significantly high in T1 as compared to other treatments. It is therefore, recommended that treatment T1 {NPK (1.0:0.5:1.0kg) + NSP (10.0kg) + GSL (20.0kg)}/palm/year was enough to improve the morphological characters to enhance future productivity.

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.

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.
