Background: Lac is a resin secretion of insects [Kerria lacca (Kerr)], which are commercially cultivated through ages. Lac cultivation has its roots in India and a major source of economy to the local populace. Though different lac hosts have been recorded in Rajasthan, but it is not cultivated commercially. Pigeonpea crop could be utilized for encouraging lac cultivation in the region and yield losses can be compensated by additional income received from lac resin. Methods: The experiment on “Studies on Economics and Yield Attributing Parameters of Lac Cultivation on Yield of Pigeonpea, Cajanus cajan (L.) in Southern Rajasthan” was conducted on Rangeeni strain of lac insect in Baisakhi season at lac insect gene bank cum garden situated at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during 2019-20 and 2020-21 respectively. The life cycle of Rangeeni strain of lac insect were studied on pigeonpea sown in last week of August in plot size measuring 2 × 10 sq m during Baisakhi season of both year. Result: The study revealed that the mean initial settlement density of lac insect on pigeonpea ranged from 67.53 to 84.20 with 4.27 to 5.27 (per sq. cm) mature female cell density during successive years. The mean per cent settlement was found to be the maximum (91.78 and 91.15%) at lower portion of the pigeonpea plant during respective years. The duration of sex differentiation ranged from 48.23 to 49.10 days for both successive years. The benefit cost ratio was also higher (1.95 and 2.09) in lac inoculated experiment then the sole seed crop (control) of pigeon pea (1.84 and 1.35) in season 2019-20 and 2020-21, respectively. All the parameter revealed that pigeon pea is economically efficient host for the Rangeeni strain of lac in agro-climatic region of southern Rajasthan.

Background: Pulse crops are commonly known as poor man’s meat. Pigeon pea is second most important pulse crops of India after chickpea. Weeds are amongst prime biotic factors limiting pigeon pea yield and can cause seed yield losses up to 80 per cent. Promising result of weed control by pendimethalin was documented in pigeon pea. Also Imazethapyr is applied as pre and post emergence to control grasses and broad leaved weeds in other pulse crops but limited research was undertaken in pigeon pea. Therefore, current experiment focused to compare the effect of imidazolinones alone and in combination in pigeon pea. Methods: To control weeds in pigeon pea, pre and post-emergence of imidazolinones alone and in combination with pendimethalin was applied. Nutrient content, nutrient uptake, productivity and economics of pigeon pea were worked out.Conclusion: Among herbicidal treatments, the highest nutrient content, nutrient uptake, productivity, net returns and benefit cost ratio in pigeon pea were observed in the pre-emergence application of pendimethalin + imazethapyr @ 1000 + 75 g ha-1. Therefore, this treatment may be an effective and profitable alternative to the existing manual and costlier recommendation (two hoeing at 25 and 45 DAS) of weed control in pigeon pea in Haryana locality.

Surveys were conducted in 28 districts of Bihar for occurrence of natural population of lac insect; Kerria lacca Kerr (Hemiptera, Tachardiidae), and abundance of its host plant. Naturally occurring lac insect was observed in 18 districts in varied proportion mostly on Ficus religiosa, Ficus benghalensis and rarely on Ziziphus mauritiana and Butea monosperma. Majority of insects were found dead but at few places good live population were noticed. Natural occurrence of lac insect was found highly vulnerable to human interventions, high temperature and parasitoids and predators. Out of 17 districts of south Bihar, falling under zone III, 10 districts were found rich in naturally surviving lac insect. Lac insects in scattered manner were also observed in many districts of Northern Bihar but occurrence and population densities were very low. Survey revealed the abundance of lac host and natural population of lac insects in various districts of zone III (58%) of Bihar. These findings could open a new window for introduction lac cultivation in these areas for livelihood support to resource poor farmers, especially during off-agricultural season.

The research on, ‘Studies on rainwater harvesting and reutilization for protective irrigation with farm pond’ was conducted during the year 2016-17 at demonstration farm of the Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The daily depth of water impounded in the farm pond was recorded for developing stage-storage relationship of the farm pond. For estimation of the loss of water through evaporation from farm pond, daily pan evaporation data was multiplied by pan co-efficient (0.70). The harvested water in the farm pond was utilized for applying protective irrigation to the pigeon pea crop. The experiment consisted six replications and two treatments. One protective irrigation for pigeon pea at pod development stage (T1) was applied on 30.11.2016. The treatment T2 consisted without protective irrigation to pigeon pea. The grain yield of pigeon pea was recorded plot wise.The grain yield data was analyzed using MAUSTAT software and results obtained were compared treatment wise. For economic analysis of the treatments, cost of cultivation, cost of cultural operations, fixed and operational costs of pump and accessories were calculated. These total cost was be used to determine the gross monetary returns (GMR), net monetary returns (NMR) and benefit cost ratio (B:C ratio). The area of top section and bottom section of the farm pond was 279.75 m2 and 516.82 m2 respectively. The average elevation of embankment at top was 413.130m. The average elevation of bottom of pond was 410.210m. The elevation at the bottom of outlet was 412.437m. The maximum depth of water impounded and maximum storage volume in the farm pond was 2.165m and 933.99m3 respectively. The total water evaporated through farm pond for the month of July, August, September, October, November and December 2016 was found to be 19.14 m3, 32.60m3, 25.40 m3, 35.9882m3, 29.8620m3 and 1.1965 m3 respectively. The maximum water evaporated through the farm pond was recorded in the month of October-2016. Total evaporation loss through the farm pond recorded was144.17 m3.The seepage loss through the pond for the month of July August, September, October, November and December 2016 was found to 634.88, 358.05 m3, 651.80 m3, 611.64 m3, 147.33 m3, and 37.89 m3 respectively. The maximum water seepage through the farm pond was recorded in the month of September -2016.The total seepage loss recorded through the farm pond was 2441.59 m3. The harvested water in the farm pond was utilized for irrigating the pigeon pea crop at its pod development stage. One of protective irrigation (T1) recorded significantly higher pigeon pea grain yield than treatment of without protective irrigation (T2). Due to the one protective irrigation, 27.30 per cent grain yield increased over or control was observed. The study revealed that the treatment T1 i. e. one protective irrigations at pod development stage recorded highest GMR (111302.00Rs/ha) and NMR (76302.00) as compared to control (T2) i. e. without protective irrigation. The benefit- cost ratio (2.18) is found to be higher under the treatment T1i. e. one protective irrigation pod development stage. The lowest B:C ratio (1.69) is estimated under the treatment T2 (without protective irrigation).

Fish marketing is gaining prominence especially in the rural communities as an all year-round poverty alleviation micro-enterprise requiring low capital base. This study examined the marketing performance of smoked and fresh fish in the study area. Primary data were obtained from 80 respondents selected through a two-stage sampling technique. Data were analysed using descriptive and inferential statistics. The objectives of the study were to: describe and compare the market structure and performance, determine the profitability, identify marketing intermediaries, and constraints to smoked and fresh fish marketing in the study area. The results showed that that both sexes involved in fish marketing with the female (58.7%) dominating. Majority (67.5%) of the marketers were within the age group of 15–44 years. The mean age was 33 years. Also, 73.7% of the respondents were married and most (58.7%) of the respondents had household size of between 1 and 5 persons and the mean household size was 6 persons. About 65% of the respondents had one form of education or the other. The mean fish marketing experience was estimated at 15 years. The benefit cost ratio for fresh fish marketing was ₦0.26. This implies that ₦0.26 was made for every ₦1 invested in the fresh fish business and the marketing efficiency for fresh fish marketing was calculated at 2.93 (293%), while the net benefit cost ratio of smoked fish was calculated at ₦1.57. This implies that ₦0.57 was made on every ₦1 invested into the smoked fish enterprise. The results further indicated significant revenue differential between smoked fish (₦380,500.00) and fresh fish (₦179,640.00) of ₦200,860.00. This accounted for about 111.82% indicating that smoked fish marketing yields higher revenue than fresh fish, in the study area. The Gini-coefficient (GC) for both fresh and smoked fish marketers were calculated at 0.5857 and 0.4801 respectively. Decentralized routes of marketing channels were observed with retailers having the highest percentage of 32.5 for the traded smoked fish, while consumers had the highest (30.0%) of the traded fresh fish. Some of the identified constraints include; seasonality, inadequate credit, poor storage facilities and poor road networks. It was recommended that the marketers organize themselves into cooperative organizations and set up strong market networks and linkages in order to benefit from available markets outside their immediate vicinities.

Pod fly [Melanagromyza obtusa (Malloch)] is a key biotic constraint for productivity in subsistence crop protection pattern; its damage varies up to 80%; has been estimated about US $ 256 million annually. The research trial was accomplished at Research Farm of SASRD, Nagaland University during Kharif 2011 and 2012 in order to evaluate the new molecules against pod fly. The experiment was consisted 6 treatments (Trizophos 500 g ai. ha-1, Emamectine benzoate 11 g ai. ha-1, Emamectine benzoate 11 g ai. ha-1 + Acetamiprid 30 g ai. ha-1, Flubendiamide 47 g ai. ha-1, Chlorantraniliprole 40 g ai. ha-1 and Spinosade 75 g ai. ha-1) compare with control. The lowest pod damage (9.7% and 9.3%), lowest grain damage (5.3% and 5%) and highest grain yield (1202 kg ha-1 and 1209 kg ha-1) were obtained from Chlorantraniliprole followed by Emamectine benzoate+ Acetamiprid, Spinosade, Emamectine benzoate, Flubendiamide, Trizophos and all the treatments were significantly superior over control. The highest B: C ratio reward (1:4.24) was obtained from Chlorantraniliprole. The results indicated that Chlorantraniliprole was more effectual against pod damage, grain damage, yield and B: C ratio. The safer chemical control methods reduce the pod damage, grain damage and higher yield with high benefit: cost ratio, so therefore chemical control popularizes as an effective, practical alternative and makes lucrative cultivation of pigeon pea.

A research was conducted at Pyuthan district in order to access the profitability of rice production in Pyuthan during the summer season of 2018-2019. Altogether of 70 respondents were selected randomly and surveyed with semi-structured interview schedule. The results revealed that the average land holding was 0.45 hectare, and the average rice cultivation area was 0.34 hectare. On the basis of average rice cultivation area, farmers were categorized as small (39) and large (31). The cost and return was calculated among both the category. t- test was used to compare the mean costs of inputs between small and large farmers. Cost for agronomic operations was found far higher (more than 70%) in both the category in compared to the cost of inputs. Contribution of rice grains and straw to overall return was 72.65% and 27.35% respectively. Benefit Cost ratio was found greater among large farmers. The average B:C ratio was 1.51, which was fairly higher than 1.14 in Dang district indicating the investment of rice production is expected to deliver a positive net return to the farmers of the study area. In a nutshell, rice cultivation is an important enterprise that should be encouraged, considering the fact that it is a major staple crop.
