Decision making pattern of farm women related to horticultural crops production in Raisen District of Madhya Pradesh
The present study was conducted in Raisen district of Madhya Pradesh during 2020-21 at the school of Agriculture sciences BRAUSS Mhow, M.P. The main objective of the present research was to study the decision making pattern of farm women related to horticultural crops production. For this study 180 randomly selected farm women were taken as a sample from study area. The study revealed that majority of the farmwomen belonged to medium decision making pattern related to horticultural crops production followed by low and high decision making pattern of horticultural crops production respectively.
Evaluation of different crop regulation methods on reproductive parameters of Guava (Psidium guajava L.) cv. G- 27
A crop regulation study was carried out on six- seven year old orchard of guava cv. G-27 during 2020-2021 and 2021-2022 to evaluate the effect of different crop regulation methods on reproductive characteristics. The experiment was laid out in Randomized Block Design comprised of 16 treatments with 3 replication consisting of foliar spray of KI (0.5 %, 0.75 % and 1.0 %), NAA (400 ppm, 600 ppm and 800 ppm), Ethephon (600 ppm, 1200 ppm and 1800 ppm), bending of lateral branches with partial removal of old leaves (mid-April, mid-May and mid-June) and shoot pruning (up to 15 cm, up to 30 cm and up to 45 cm) with complete removal of old leaves and water spray as control. The result showed that all the treatment were significantly effective in summer deblossoming for avoiding rainy season crop and induce profuse flowering and fruiting during winter seasonin both the year as well as pooled data over to control. Among the treatments, foliar spray of NAA 800 ppm was recorded significantly maximum number of buds per plant (483.83), number of flowers per plant (431.36), fruit set (75.92 %), fruit retention (50. 94 %)and minimum bud drop (10.85 %) and flower drop (49.06 %), which was at par with bending of lateral branches with partial removal of old leaves in mid-June as compared to other treatments in pooled data. In case of minimum days taken to initiation of flower bud (39.67 days) was recorded significantly result under treatment of bending of lateral branches with partial removal of old leaves in mid-June followed by bending in mid May as compared to other treatments during pooled analysis.
Achieving higher yields in bell pepper infested with Meloidogyne incognita in organic protected cultivation by soil solarization and application bioagents in Haryana, India
In protected bell pepper cultivation, the root knot nematode Meloidogyne incognita poses a severe threat in North and South India. Growers resort to costly synthetic nematicides, which not only inflate expenses but also exhibit phytotoxicity. To address this, a two-year experiment in Badoli village, Panipat, aimed to save a farmer from dismantling his polyhouse due to three years of losses. Soil solarization was performed for two consecutive years, resulting in an 80.19% and 75.74% reduction in M. incognita in the first and second years, respectively. In the first year, soil solarization with Trichoderma viridae and in the second year with Pochonia chlamydosporia led to the greatest reduction in M. incognita populations in soil and roots. Interestingly, soil solarization with Pochonia chlamydosporia increased the population of free-living nematodes (35.10% and 23.11% above control in the first and second years, respectively), enhanced plant growth (5.89% and 2.64% above control at harvest), and yielded significantly more (25.07 t/ha, a 46.35% increase over control). The farmer's profit surged to Rs. 5.79 lakhs, compared to a meager Rs. 1.0 lakh. Overall, soil solarization alone reduced root knot nematode populations, while FYM fortified with three biocontrol agents improved plant growth, fruit weight, and capsicum quality. The approach of using 25-micron polythene sheets for soil solarization in polyhouses during May-June, combined with FYM enriched with Pochonia chlamydosporia (TNAU-Pc001) at 2 Kg/tonne FYM and 1000 g per sq m before sowing and after six months, is recommended for effective M. incognita control.
What influences the possession of Farm Machinery in Jammu and Kashmir, India?
In comparison to the nations such as USA, Brazil, and China where the rates of agricultural mechanization are 95 percent, 75 percent, and 57 percent, respectively, India's rate of farm mechanization is comparably quite low (4–45 percent). Although, the efforts are being made to enhance the adoption of farm mechanization in India, but still the adoption is far away from an ideal level. It is a proven fact that farmers can gain from the introduction of a range of agricultural equipment. However, there are many factors that differentiate between use, adoption and possession of farm machinery. This paper studied the factors affecting the possession of light and heavy farm machinery in Jammu and Kashmir, India. Multistage random sampling technique was used to select 900 respondents from three zones; sub-tropical, intermediate and temperate of Jammu and Kashmir. The binary logistic regression model was applied to find out the factors affecting the possession of farm machinery. The probability of possessing light machinery is positively affected by factors such as livestock possession, unirrigated land holding, off farm source of income, and government employment, whereas the likelihood of possessing heavy farm machinery is positively affected by plain topography, family income, land holding, off farm income and self-employment. The innovative small farm tools alongwith light machinery need to be promoted in Jammu and Kashmir. The use of heavy machinery can be promoted through Custom Hiring Centres.
Analysis of Heating and Plant Growth Characteristics with Agricultural Plasma Discharge Boiler Unit
We aimed to compare underwater plasma discharge type boiler (Group 1) and conventional electric boiler (Group 2) for the heating energy saving in greenhouses. Two type boilers were installed in Zamioculcas zamiifolia growing greenhouse. As a result, the temperature differences from the set temperature were 2.1℃, 2.5℃ for Group 1 and Group 2. The water temperature difference of Group 1 was about 23~47℃ lower than Group 2, and the water temperature in Group 1 rose faster to the set temperature. The heating energy supplied to greenhouse tended to be high in Group 2, and there was no significant difference in the amount of heat loss according to heating methods. In addition, growth characteristics of Zamioculcas zamiifolia were investigated according to the heating methods, and leaf length, leaf width, tree height, and NDVI (Normalized difference vegetation index) were measured. As a result, it was confirmed that there is no significant difference according to the heating methods. Thus, we considered that the underwater plasma discharge type boiler can be used to heat greenhouse. The energy consumption were 5,051 kWh, 6,073 kWh for Group 1 and Group 2, so it was found that the underwater plasma discharge type boiler had about 17% heating cost saving effect.
