Effect of date palm wastes and rice hull mixed with soil on growth and yield of cucumber in greenhouse culture

Okra or Lady’s finger, botanically known as Abelmoschus esculentus (L.) Moench, is a tropical and sub-tropical indigenous vegetable crop commonly grown for its fibrous, slimy, and nutritious fruits and consumed by all classes of population. It has also several medicinal and economic values. Despite its many uses and potential value, its importance is under estimated, under-utilized, and considered a minor crop and little attention was paid to its improvement. The study was conducted to evaluate the effects of different planting densities and mulching materials on the growth and yield of okra grown in slightly sloping area in the marginal uplands in Sta. Rita, Samar, Philippines. A split-plot experiment was set up with planting density as main plot and the different mulching materials as the sub-plot which were: unmulched or bare soil, rice straw, rice hull, hagonoy and plastic mulch. Planting density did not significantly affect the growth and yield of okra. Regardless ofthe mulching materials used, mulched plants were taller and yielded higher compared to unmulched plants. Moreover, the use of plastic mulch resulted to the highest total fruit yield. The results indicate the potential of mulching in increasing yield and thus profitability of okra production under marginal upland conditions.

Dual Treatment

Fresh date palm fruits (cv. Barhi) have received much attention due to their sweet taste and popularity in marketing. There is a critical need to prolong their storability, as well as maintain their quality during the postharvest and marketing periods. In this study, the effects of spraying date palm trees with melatonin (Mt) and/or methyl jasmonate (Mj) at 10, 20, and 50 ppm, on their growth and yield were investigated. In addition, impacts on quality and storability of the fruits were also studied. In general, application of Mt was mostly more effective than that of Mj, even at 50 ppm, with regard to all evaluated parameters. However, the dual treatment at 50 ppm recorded the highest relative chlorophyll and nutrient content in date palm leaves, as well as the yield and its components. Regarding the date palm fruits stored at 4 °C for 28 days, this dual treatment recorded the lowest weight loss and fruit decay values (0.14 and 2%, respectively), the highest firmness (6 g·cm−2), total soluble solids content (36 °Brix), total sugar content (32.5 g/100 g fresh weight), and the lowest total acidity (0.16 g citric acid/100 mL juice). Moreover, the highest total phenolic content and activity of peroxidase and polyphenol oxidase enzymes in the stored fruits were also recorded for the dual treatment. In contrast to the untreated fruits, scanning electron microscopy observations showed that the sprayed fruits had a very good microstructure, showing intact and thick exocarp tissue with a dense layer of epicuticular wax. The mesocarp tissue showed a normal and clear cellular framework with well organized and arranged cells, after 28 days storage at 4 °C. Based on these results, we can conclude that application of the dual treatment (Mt + Mj) at 50 ppm is a promising way to prolong the storability of date palm fruits and maintain their quality during storage periods.

The objective of this study was to evaluate the influence of substrates on the growth and yield of Cascade and Samambaia cherry tomato cultivars under protected environment. A completely randomized experimental design with six treatments and four replications was adopted. The treatments consisted of six substrates resulting from the combination of soil (CS), bovinemanure (BM), rice husk (RH) and rice hull ash (RA), in the proportions: S1 -70% SC + 10% BM + 10% RH + 10% RA; S2 -60% SC + 20% BM + 10% RH + 10% RA; S3 -50% SC + 30% BM + 10% RH + 10% RA;S4 -60% SC + 30% BM + 10% RH; S5 -70% SC + 20% BM + 10% RH; and S6 -100% SC. Plant growth, yield and development parameters were evaluated. Cherry tomato growth and yield changed according to the substrate characteristics. The substrate composed by soil was not efficient, presenting the lowest values for all the vegetative and reproductive parameters studied. The substrates made from alternative ecologically based residues are interesting and alternative sources for tomato cultivation aiming at the reuse of the matter and the sustainability of the production system.

The Media

AbstractNutrient disorder and presence of disease-causing agents in soilless media negatively influence the growth of muskmelon. To combat these issues, use of environmentally-friendly sanitation techniques is crucial for increased crop productivity. The study was conducted under greenhouse and field conditions to investigate the effect of two different sanitation techniques: steaming and formalin fumigation on various media’s characteristics and their impact on muskmelon yield. Media: jantar, guar, wheat straw and rice hull and peat moss of 10% air-filled porosity and sanitized with formalin and steaming. Steaming of guar, jantar, and wheat straw increased the phosphorus (P) and potassium (K) concentrations by 13.80–14.86% and 6.22–8.45% over formalin fumigation. Likewise, P and K concentrations in muskmelon were higher under steaming. Steaming significantly inhibited the survival of Fusarium wilt sp. melonis, root knot nematode sp. meloidogyne and nitrifying bacteria in media than formalin fumigation. In conclusion, steaming decreased the prevalence of nitrifying bacteria and pathogens which thus improved the NO3−–N:NH4+–N ratios, P and K nutritional balance both in the media and muskmelon transplants. Hence, steaming as an environment-friendly approach is recommended for soilless media. Further, optimization of steaming for various composts with different crops needs to be investigated with steaming teachnique.

A field trial was carried out with rice (BRRI 64) grown in saline soil at Kuakata of Patuakhali District to evaluate the potential of rice straw, rice hull and saw dust each applied at the rates of 0, 4, 8 t ha-1 in moist and saturated conditions. Growth parameters and yield of rice were found to increase significantly (p ≤ 0.05) with the increased rates regardless of kinds of organic treatments under both the conditions. The highest plant heights (89 cm in moist and 101 cm in saturated condition) were recorded at maturity in the treatment, which received the combination (RH8RS8SD8) of highest rates of these 3 organic amendments. The lowest plant heights (73 cm in moist and 77 cm in saturated) were recorded in control condition (RH0RS0SD0). The maximum numbers of tillers were observed in RH8RS8SD8 and RH8RS4SD8 followed by RH8RS8SD4, RH8RS4SD4 and RH4RS8SD8 treatments at saturated condition. The straw dry matter and grain yields of rice were also found to vary significantly (p ≤ 0.05) due to single application of rice hull, rice straw, saw dust and moisture conditions but their combined effects were found to be significantly better at the higher levels. The highest grain yield (6.6 t ha-1) was recorded in RH8RS8SD8 treatment followed by RH8RS8SD4, RH8RS4SD8, RH8RS4SD4 and RH4RS8SD8 at saturated condition. Growth and yield of rice were attained better at saturated condition than that of the moist soil. Asiat. Soc. Bangladesh, Sci. 43(2): 197-206, December 2017

Set Up

Basella or malabar spinach locally known as alugbati is a tropical leafy, indigenous vegetable commonly grown for its succulent, nutritious, and tender stems. It has also a number of medicinal applications. Despite its many uses and potential value, its importance is under estimated. The study was conducted to evaluate the effects of different mulching materials on the growth and yield of two Basella species grown in a rolling soil in the marginal uplands of in Inopacan, Leyte. A factorial experiment was set-up with Alugbati species/varieties as the main plot factor and the different mulching materials as the sub-plot. Treatments were: T0 – control, T1- rice hull, T2 – rice straw and T3 – plastic mulch. Basella alba, the green-stemed alugbati had significantly bigger stems, greater number and heavier shoots than the red-stemed Basella rubra. Leaf spot disease caused by Colletotrichum sp. was more evident in B. rubra. Regardless of the mulching materials used, mulched plants yielded higher than the unmulched plants or those planted in bare soil. Moreover, the use of silver plastic mulch resulted to the highest total yield. The results indicate the high potential of mulching in increasing the yield and thus the profitability of alugbati production.
