Dryland Ecosystems

Background: Maize-wheat is the predominant cropping system of dryland ecology of Jammu region, but due to their comparatively higher input requirements especially of nutrients and water under the fragile ecology of these dry lands an untenable threat has been posed to their factor productivities. Therefore, all cropping sequences that suit and sustain better on the natural resources of the dryland ecosystems for a longer period of time needs to be explored.Methods: The treatments consisted of two oilseeds i.e. mustard) and gobhi sarson and two pulse crops i.e. chickpea and field pea taken during rabi were followed by two oilseed i.e. soybean and sesame and two pulse crops i.e. green gram and black gram grown during kharif. The experiment was laid out in randomized block design with four replications.Result: Significantly higher chickpea equivalent yield of green gram was observed with field pea- green gram sequence (10.26 q/ha) which was at par with the chickpea – green gram and field pea - black gram system. The available nitrogen status was significantly influenced and recorded highest (166.82kg/ha) under field pea- green gram system. Further overall nutrient mining by this system was quite low as compared to other systems.

Pests And Diseases

Green gram (Vigna radiata (L.) R. Wilczek) is one of the most economically important grain legumes of the traditional farming systems of Sri Lanka because it is a cheap source of protein and animal feed, and sustains soil fertility by fixing atmospheric nitrogen. Weeds are one of the major problems in green gram cultivation, reducing the yield through competition, interference with harvest and harboring pests and diseases. Controlling of weeds by applying herbicides would definitely cause unexpected damage to human health and the abundant biodiversity of Sri Lanka. Therefore, an investigation was planned to evaluate the yield loss due to weeds and to determine the optimum weed free period to minimize the yield losses. Two experiments were performed. The first experiment was conducted to determine the effects of different weed functional groups on the yield of green gram. In the second experiment, weeds were continuously hand weeded and areas kept weed free. In the third, weeds were allowed to compete with green gram until 2, 3, 4, 5 or 6 weeks after cultivation. All the treatments were conducted in randomized complete block design with three replicates. The data collected on types of weed, number of pods and pod weight at 3–6 weeks after planting (WAP) were analyzed using the SAS 9.4 statistical package, and DMRT was performed to determine the best treatment combination. The results from the first experiment showed that average yield loss due to total weed populations was 54.77%. Yield loss due to grasses alone was 46.56%, far worse than broad leaves (16.49%) and sedges (18.01%) at p < 0.05. Crop stand count at 3–4 WAP was not significantly different among treatments. However, biomass weight of 50 plants, number of pods in 50 plants and grain weight of 10 plants were found to be significantly different after 3–4 WAP in weed free conditions at p < 0.05%. When the weed free period increased, the yield was increased until 3 WAP; thereafter, not significant yield increment was observed. In contrast, yield steeply declined in plots that had weeds until 3 WAP. According to the results of the present study, it can be concluded that the critical weed free period from the planting of green gram is 3 WAP. Maintaining a weed free period for 3–4 weeks is recommended to minimize the yield loss of green gram at minimal weed management cost.

Three cropping systems using 5 crop species were compared over a 10-year period on a cracking clay soil (Vertisol) in the sub-humid subtropics of eastern Australia. The 3 cropping systems were continuous (the same crop every year), alternate (the same crop every second year) and double (a winter and summer crop in the one year). There were 2 cereal crops (sorghum and wheat) and 3 grain legumes (chickpea, green gram and black gram). The effect of cropping system was measured in terms of grain and protein yields and changes in soil organic carbon (surface 0-10 cm) and nitrogen concentrations. Summer and winter rainfall was below average in 8 and 5 years out of 10, respectively. Grain yield of cereal monocultures was about twice that of legume monocultures. The potential for double cropping, despite the generally below-average rainfall, was clearly shown with the highest grain and protein yields coming from the combination of green gram (summer) and wheat (winter). Averaged over 10 years, wheat yield (1460 kg/ha. year) was identical in the continuous and alternate cropping systems. Sorghum yields were marginally higher with alternate cropping (1340 kg/ha. year) than continuous cropping (1050 kg/ha. year). With double cropping, average wheat yields were 1081 and 698 kg/ha when combined with green and black gram, respectively. Black gram gave half the average yield of either green gram or chickpea (about 300 v. 600 kg/ha). This was attributed to the indeterminate nature of the crop in an environment with variable rainfall and to the detrimental effect of above-average rainfall during harvest time. Soil nitrogen and carbon levels, with initial values of 0.22 and 2.96%, were reduced at the end of 10 years by 16 and 27% respectively. Their rate of decline did not differ between cropping systems.

The Impact

Most of the pulses in India are grown in low fertility, problematic soils and unpredictable environmental conditions. Major issues in pulse production are poor establishment and low harvest index. In pulses harvest index is only 15-20%. Physiological manipulations such as spraying of hormones and nutrients that reduce flower drop and thereby facilitate large sink size. The objective of this research is to study the impact of Growth regulating substances on germination and establishment and economic yield of black gram and green gram under Sodic soil conditions. The study area is Anbil Dharmalingam Agricultural College and Research Institute, Trichy. The nature of soil is sodicity with exchangeable sodium percentage (ESP) of 18.94% with pH of 9.02. The two crop varieties green gram VBN (Gg) 2 & black gram VBN (Bg) 6 were employed under sodic soil condition. Field experiment was conducted during late July to October 2017 under sodic soil condition with ten treatments. The experiment was laid out in a Randamized Block Design with three replications. Foliar spray was given at flower initiation and pod initiation stages. Ten treatment combinations were employed by T1: Control, T2: Seed Treatment (ST) with Ammonium Molybdate (AM) 0.05% + foliar spray of ZnSO4 – 0.5%. T3: AM 0.05% + Panchagavya -3.0%,              T4: AM 0.05% + foliar spray of KCl -1%, T5: ST with GA3 50 ppm + foliar spray of ZnSO4 – 0.5%,   T6: GA3 50 ppm + Panchagavya -3.0%, T7: GA3 50 ppm + KCl -1%, T8: Cowpea Sprout Extract 2% +ZnSO4 – 0.5%, T9: Cowpea Sprout Extract 2% +Panchagavya -3.0%, T10: Cowpea Sprout Extract 2% + foliar spray of KCl -1%. In conclusion the yield enhancement in best treatment may be due to the presence of bioactive substances in sprouted cowpea extracts and panchagavya were found effective towards yield maximization.

Drought is one of the major abiotic stresses which adversely affect crop growth and production worldwide as water is vital for every aspect of plant growth and development. The present experiment was carried out during the growing seasons (September – December) of 2012 and 2013 to evaluate the response of black gram (Vigna mungo L.) and green gram (Vigna radiata L.) in terms of some important growth indices, biochemical traits and seed quality under drought stress. Four commonly grown genotypes - T9, KU 301(black gram) and Pratap, SG 21-5 (green gram) of Assam, India were grown in a randomized block design with three replications under stress and non-stress conditions. Stress was applied by withholding irrigation for fifteen consecutive days at vegetative, flowering and pod filling stages. Leaf area index (LAI), seed protein content and protein yield significantly decreased (p ≤ 0.01) whereas proline, total flavonoids and anthocyanin content increased significantly (p ≤ 0.01) in response to water deficiency. Among the studied genotypes, T9 and Pratap showed better tolerance capacity towards the applied drought by presenting higher values of LAI, plant height stress tolerance index (PHSI), dry matter stress tolerance index (DMSI), proline, total flavonoids, anthocyanin, lower percentage of chlorophyll degradation and finally producing high quality seeds.

Fried Snack

Woh is a deep oil fried spongy Nepalese indigenous product. This work was done to find out the basics of woh and to prepare best from different formulations using unlike particle size and different frying media. Green gram and black gram in a ratio of 100:0, 50:50, 60:40, and 70:30 were mixed and ground on stone grinder and mixer grinder for different particle sizes. Batter mixed with spices were whipped and deep fried in mustard, soybean and sunflower oil separately at 204 ± 2ºC for 2.5 ± 0.5 minutes. Woh with 60:40 combination having 103 μm particle size fried in soybean oil was found to be nutritious with less oil uptake and less anti nutritional factors.DOI: http://dx.doi.org/10.3126/jfstn.v8i0.11747 J.
