This paper reports the productivity of a small-scale pilot biofarm of grey oyster mushroom (Pleurotus sajor-caju (Fr.) Sing.). The pilot was tested in Mekelle city (Ethiopia) in a brick-walled dark room. Growing structures were constructed by erecting three wood poles and fixing them with three wooden side bars at multiple locations to make a prism-shaped rack with multiple triangular open shelves, each capable of carrying one bag of spawned substrate. Mushroom substrates were prepared from maize stalk and wheat bran supplement. Pasteurized chopped maize stalk and wheat bran were mixed at the ratio of 10:0, 9:1, 8:2, and 7:3—yielding four treatments. Five kilograms of substrate was taken from each treatment and was mixed with one kilogram of gypsum to produce a growing mass. Each mass was spawned with 200 g of inoculum under aseptic conditions and put in polyethylene bags. The treatments were replicated thrice and the bags were put on the growth racks in completely randomized design. The growing room was maintained at optimum conditions. Maize stalk substrates supplemented with 10% and 20% of wheat bran have resulted in statistically comparable productivities but statistically significantly higher than those grown on nonsupplemented and highly supplemented maize stalk substrates (p ≤ 0.05). The ingenuity of the design and the convenience of the construction of the racks, the availability of the substrates, and the simplicity of the management and maintenance of the biofarm rendered the piloted design suitable for home-based and small- and medium-scale mushroom biofarm entrepreneurship.

The growth performance and blood profile of forty-eight (48), six (6) weeks old rabbit bucks of cross (Chinchilla and New Zealand White) were assessed for 10 weeks. The bucks were allotted on weight equalization basis in a 2 x 4 factorial experimental layout composed of 24 rabbits into steel hutches and wooden hutches each and on four (4) varying levels (0, 5, 10 and 15 mL/litre of water, respectively) of oyster mushroom (Pleurotus ostreatus Jacq ex fr.) extract. Six (6) bucks were assigned to each treatment group and replicated three times with two (2) bucks per replicate in a Completely Randomized Design. The phytochemicals of the oyster mushroom extract showed that 9,12-Octadecadienoic acid (Z, Z)- methyl ester was the most abundant. Results showed that the feed conversion ratio was significantly (P<0.05) best (6.08) in bucks reared in wooden cage and administered 15 mL oyster mushroom extract. Significantly (P<0.05) highest triglycerides (81.00 mg/dL) was obtained in bucks on steel hutch and on 5 mL oyster mushroom extract and lowest (55.00 mg/dL) in bucks on steel hutch and on 10 mL oyster mushroom extract. The lowest (P<0.05) lymphocytes (59.00%) were recorded in bucks on wooden cage and administered 10 mL oyster mushroom extract. It was concluded that oyster mushroom extract up to 15 mL/litre of water administered in either steel hutch or wooden hutch did not impair the growth performance and blood profile of rabbit bucks.

This study was to evaluate the growth response of Archachatina marginata as influenced by four natural diets: Pawpaw (Carica papaya) cocoyam (Colocasia esculenta), cocoyam (Xanthosoma sagittifolium), and cassava (Manihot esculenta) leaves and growers mash (a compounded ration). One hundred and twenty (120) grower snails (Archachatina marginata) were purchased from a farm in Ibadan, Oyo State. Data were collected on the growth parameters (weight, length and circumference of shell of the snails arranged in a Completely Randomized Design and replicated three (3) times. The results showed that pawpaw (Carica papaya) recorded the highest mean in all the parameters measured and throughout the duration of the experiment. Cocoyam (Colocasia esculenta) leaf had a better mean than the Cassava (Manihot esculenta) leaves in terms of weight gained whereas the reverse is the case in terms of length and circumference of shell. Pawpaw (Carica papaya) is therefore, recommended to both local and small scale farmers in Abia State and in Nigeria for feeding their snails and cocoyam (Colocasia esculenta) leaves and growers mash as an alternate feed.

The evaluation of seed priming methods on the seed and seedling performance of soursop was conducted January 9 to April 3, 2019 in San Nicolas, Ilocos Norte, Philippines.  The study was conducted to investigate the effect of seed priming methods  capable of breaking dormancy; improve germination rate; determine the seed vigor of soursop; and identify the best seed priming method that provide better seedling performance. The experimental  treatments (unprimed and three priming methods, hydropriming, halopriming and hormonal priming) were laid out in Completely Randomized Design with three replications. A     total of 20 polyethylene bags were used per treatment per replication with one seed sown in every bag. Alternative way to improve seed and seedling performance is the use of these seed priming methods. The seed and seedling performance of soursop were significantly affected by priming methods. Primed seeds had higher percentage germination rate (PGR) than unprimed seeds. But numerically, the highest PGR was hydropriming. Hormonal priming produced significantly taller seedlings at 10 and 40 days after emergence (DAE) than unprimed seeds and more leaves per seedling at 30 to 50 DAE. Hormonal, hydropriming and halopriming produced significantly higher fresh weight of seedlings than unprimed seeds.

Oyster mushrooms have the conditions of growing at low temperatures and high relative humidity, so when you want to cultivate it is needed an appropriate environment for the growth and development of oyster mushroom. Banjarbaru City tends to have high temperatures with a relative humidity that tends to below. This is quite different from the requirements for growing oyster mushrooms which require low temperatures with relatively high humidity. One of the easiest and cheapest methods to maintain temperature and relative humidity to remain ideal and appropriate is to water the surrounding oyster mushrooms growing media, so knowledge of the most appropriate and ideal watering frequency for growth and development of oyster mushrooms is needed. The environmental design used was a Completely Randomized Design (CRD), a single factor with 4 treatments, 5 replications, so that 20 experimental units were obtained. The treatments are p1 = once watering per day, p2 = twice watering per day, p3 = three times watering per day, p4 = four times watering per day. The result showed that the watering frequency gave a real difference to the growth time of oyster mushroom shoots and the wet weight of oyster mushrooms. The best treatment in accelerating the time to grow oyster mushroom shoots and increasing the wet weight of oyster mushrooms is the treatment of watering frequency four times per day.

In Brazil, eggplant and gilo are important for the economy of small-scale farms located mainly in the southeast states and other regions, with a significant production volume year-round in the wholesale local markets. However, these species are very susceptible to root-knot nematodes, and there are few or almost none known sources of resistance. The objective of this studywas to prospect sources of resistance to root-knot nematodesin eggplant, scarlet eggplant (gilo), as well in interspecific hybrids between these species and with wildSolanumspecies, to be used as rootstocks. In the first experiment, in 2013,10 eggplant accessions, a hybrid between eggplant andgilo, and a Solanum stramonifoliumxeggplanthybrid, were evalu41atedfor theirreaction to Meloidogyne enterolobii. In the second, in 2016, 20 accessions of gilowere evaluated for their reaction to M. incognita, M. javanica,and M. enterolobii.. And in the third experiment,in 2017,one access and two experimental eggplant hybrids, and one Solanum scuticumx eggplant hybrid, were evaluated for their reaction to M. incognita, and M. enterolobii. All the trials were stablished inagreenhouse, and characters related to root infection were evaluated in a completely randomized design with six replications of one plant per pot, usinga 1.5 L pots filled with a mixedsubstrate inoculated with each nematode species.Itwas found thatall eggplant accessions were susceptible to M. incognitaand M. enterolobii, however, BER 3150 presented lower susceptibility to M. incognita. The gilogenotypes CNPH 056, CNPH 070, CNPH 220,and CNPH 363 shownbetter response to M. incognitaand M. javanicathan the susceptibility pattern, the tomato 'Rutgers'. Other giloaccessions CNPH 070, CNPH 219,and CNPH 387 showed better or equivalent response thanthe resistant tomato 'Nemadoro' for M. enterolobii.4-the BER EG203 x S. scuticuminterspecific hybrid can be recommended as a rootstock for eggplant susceptible to M. incognita, as well the wild S. stramonifoliumvar. inerme species for M. enterolobii.

Coconut Coir

An experiment was conducted at Mushroom Lab of Horticulture Centre under Department of Agricultural Extension (DAE), Khairtala, Jessore to determine the performance of different substrates on the yield of oyster mushroom (Pleurotus ostreatus). Sugarcane bagasse, sawdust, and coconut coir individually and their combinations were used as substrates. The experiment was laid out in Completely Randomized Design (CRD) with five replications. Data were taken from 1st and 2nd flush of different growth and yield attributes of mushroom. The maximum number of effective fruiting bodies was obtained from sawdust (40) and the lowest number (31.6) from combination of sawdust and coconut coir (1:1). In the 1st flush, the maximum weight of individual fruiting body was observed in coconut coir and minimum in sawdust. The highest biological (186.06 g) and economic yield (180.64 g) were obtained from coconut coir and the lowest from sugarcane bagasse. The maximum and minimum harvest index was found in 1st flush at coconut coir and combination of sawdust and sugarcane bagasse (1:1), respectively. Most yield attributes were found higher in coconut coir. Economic yield was positively correlated to number of effective fruiting bodies, pileus diameter, and biological yield.

The bagging of banana bunch can control chilling injury (CI) in the field, which causes browning of banana peel. The purpose of this study was to evaluate the effect of changing the bunch protection material and bagging time on the yield of 'Nanica' banana (AAA) and the occurrence of CI. The experiment was conducted in Jacupiranga, SP, Brazil. The experimental design was completely randomized design arranged in a 2 x 2 x 6 factorial scheme with eight replicates, two bunch formation periods (autumn-winter and winter-spring), two bagging times (early, before the opening of bracts, and late, after complete opening) and six treatments. Treatments were polyethylene bags with different thickness (blue bags of 3µ in thickness and black bags of 6, 8 and 10µ in thickness combined with white non-woven fabric, black bag of 10µ in thickness combined with blue polyethylene bag 5μ in thickness impregnated with insecticide) and non-bagged banana. The change of sunlight transmission with black polyethylene bags of different thickness promoted a small increase in fruit peel temperature (0.14 to 0.57°C) on colder days (8.72°C), reduced CI index and improved peel brightness (L*) and ho (hue angle), although it did not affect bunch mass. However, in late winter, sunburn increased fruit losses. Sunlight transmission in fruit peel was correlated with CI index (r=0.92*), L* (r =-0.77*) and phenols (r=0.85*). Despite not controlling CI, early bagging is recommended for increasing peel L*.

Annatto (Bixa orellana L.) is an important species for several sectors, industrial, food, landscape, among others, which uses parts of the plant or the entire plant. It is an underresearched species, although it has significant economic value for small-scale farmers. The substrate is one of the sources that directly influence the production of a perennial species that need to present good characteristics to ensure a quality seedling. Therefore, the aim was to evaluate the babassu stem decomposed in the formulation of substrates for the production of annatto seedlings. The study was carried out a shading screen with 75% permeability to light. The experiments were conducted in a completely randomized design, with four replications. The treatments consisted of substrates based on babassu stem decomposed (BSD), in the following proportions: S0: 100% soil; S20: 20% BDS + 80% soil; S40: 40% BDS + 60% soil; S60: 60% BDS + 40% soil; S80: 80% BDS + 20% soil; S100: 100% BDS. At 90 days after sowing (DAS), an evaluation of seedling growth variables was performed. A difference was found between the procedures for all the variables analyzed. There was a difference between treatments for all variables analyzed. The substrate constituted of 60% babassu stem decomposed is the most appropriate for the production of taller annatto seedlings.
