Eight different kinds of papers, viz., glaze paper, brown paper, news paper, magazine paper, chart paper, kite paper, rough copy paper and A-4 size printing paper, and two types of cardboard viz., corrugated cardboard and card board were evaluated for different manifestations of white oyster mushroom Pleurotus florida Strain-P1. Among them news paper was later treated as a control. The mushroom was utilized all the substrates for their growth and sporophore formation. Majority of substrates were taken almost equal time for spawn run, primordial development and fruiting bodies maturation. The measured parameters were net yield (Weight of fresh mushrooms), biological efficiency, number of fruiting bodies produced and average weight of sporophores varied among themselves. The crop of mushroom was harvested in three flushes where yield and biological efficiency ranged 190-495 gm, 38-99% for the substrate used. Magazine paper (450 gm; 90%) and card board (495 gm; 99%) produced significan...

Irrigation scheduling is necessary for increasing onion production in an Agro-climatic zone III A and B of Bihar, where water is becoming scarce gradually and a limiting factor for onion production. Field experiments were conducted during the Rabi season of 2013-14 and 2014-15 at the experimental farm, Nalanda College of Horticulture, Noorsarai, Nalanda. The objectives were to standardize high density planting with drip irrigation and to study the yield performance and storability on onion in Nalanda region. The treatments consisted of factorial combination of three irrigation intervals (2, 4 and 6 days) and four population densities (2000000, 1333333, 1000000 and 666666 plants/ha) corresponding to 10 x 5, 10 x 7.5, 10 x 10 and 15 x 10 cm respectively. The experiments were laid out in randomized block design replicated three times. Results revealed that the highest marketable yield was significantly favoured by 2 days interval followed by 4 days. However, lower plant spacing 10 x 5 ...

Two wastes from animal origin, viz., human hairs and egg shells were evaluated for different manifestations of white oyster mushroom, Pleurotus florida. The mushroom utilized both the substrates for their growth and sporophore formation. The mycelial growth was significantly (P=0.05) faster on egg shell (18 days) as compared to human hair (23 days). The crop of mushroom was harvested in four flushes where human hairs showed higher yield and biological efficiency of mushroom (165 gm, 33%) than egg shells (155 gm, 31%), respectively. In respect of yield parameters such as yield, biological efficiency, number of mushroom fruit bodies and average weight of sporophores, both the substrates were statistically at par to each other. Utilization of human hairs and egg shells by P. florida reveals a new strategy for mycoremediation of these wastes.

To better understand nutrient transport in vegetable, a pot experiment was carried out at the nursery site of the Department of Crop Production, Federal University of Technology, Minna (9°36’ N, 6°33’ E) Niger state, Nigeria. The study aimed at determining the effect of age of celosia plant at harvest on the yield and nutritional composition of the plant as well as the concentration of nutrients at different leaf positions. The experiment was a 3 x 3 factorial combination of three harvest periods (5, 7 and 9 weeks after sowing) and three leaf positions on the mother plant (upper, middle and basal) arranged in a completely randomized design. Harvested leaves were analysed for the nutritional composition. The results showed that the whole plant fresh weight, varied significantly (p<0.05) with the age of plant at harvest, having the maximum and the minimum values at 9 weeks after sowing (266.19 g/pot) and 5 weeks after sowing (96.12 g/pot) respectively. The leaf fresh weight and lea...

Onion (Allium cepa L.) is an important commercial vegetable crop grown by small-holder farmers in Kenya for both local and export markets. The national average production is low and quality is highly compromised due to use of low yielding varieties and poor agronomic practices. Field experiments on the influence of nitrogen and time of application on growth, yield, and quality of onion bulbs were conducted in 2014 and 2015 at the National Agricultural Research Laboratories. The experiments were laid out in a Randomized Complete Block Design (RCBD) with a split-split arrangement and replicated three times. Nitrogen (N) was applied as Calcium Ammonium Nitrate at five levels including, 0 (control), 26, 52, 78 and 104 kg N ha-1. These were applied at four different times of applications at three, six, nine and twelve weeks after transplanting. Two onion varieties popularly grown in Kenya were used, the Red Creole and Red Tropicana F1 hybrid. Nitrogen and time of application showed signi...

Apple (Malus × domestica Borkh) occupies a significant place in the horticultural wealth of temperate zone. The growth and productivity of apple in Indian conditions can be optimised by replacing out-dated  depleted  standard  Delicious  cultivars  by  the  improved  high  yielding  cultivars  and  adopting standard clonal rootstocks instead of seedling stock in addition to improved management practices. The  present  investigation  was  undertaken  to  make  a  preliminary  assessment  for  studying  the performance of newly released apple cultivars viz, Lal Ambri, Sunhari, Shireen, Firdous and Akbar on clonal  rootstocks  M-9  and  MM-106. The  experiment  was  carried  out  at  the  Experimental  Farm  of SKUAST-Kashmir, and was laid out in a randomized block design with ten treatment combinations. ...
