The variation in the relative humidity in the morning (RH morning) is much smaller than in the relative humidity in the evening (RH evening) (Fig. 4). Seeds of Pusa Mustard 27, Pusa Mustard 26 and Pusa Mustard 25 (Fig. 9) were multiplied for distribution to farmers in the following season.

A total of 74 genotypes were collected from the different parts of the northeastern region cultivated from 241m MSL (Milli, Sikkim) to 2045m MSL (Darjeeling, West Bengal). 74 chow-chow germplasm were collected from the different parts of the northeastern region of India (Fig. 20), where fruit weight varied. To mark the Swachh Bharat Abhiyan, a cleaning drive was also part of the activities in the division.
The increase in Tmax along with DTR is intimate to higher incidence of the extreme temperatures. The Shannon information index was found to indicate the informative nature of the loci. The appearance of the cestode ie. the Asian fish tapeworm Bothriocephalus acheilognathi from the host fish Grass carp, Ctenopharyngodon idella is the first report of the parasite from this region.
Arkel and Vikas, which resulted in an increase of about 25 percent in farmers' adoption of the technology. But with the intervention of high yielding varieties of different vegetables, there was increase in yield as well as increase in income for the farmers. One of the major limitations of water harvesting structures in the hilly region is high construction costs and seepage losses from the storage tanks.
Mrs. Hynniew Rynghang, an adopted farmer from the village, said: “The integrated organic farming system produced very good returns with a very small amount of external inputs” (Figs. 41 and 42).
ARUNACHAL PRADESH CENTRE

MANIPUR CENTRE
Fifty days (50) old seedlings of RC Maniphou-7 showed better yield of 8.4 (t/ha) and 6.45 t/ha under semi-submerged condition for 15 and 10 days respectively. Check (Pusa Composite-3) gave the highest yield of 4.10 t/ha and 4.63 t/ha in first and second sowing followed by purple maize of Mao with 3.54 t/ha in first sowing and Tharathei of Ukhrul in the second sowing with 3.91 t/ha. In the third sowing, Tharathei gave the highest yield at 4.25 t/ha followed by Pusa Composite-3 at 3.80 t/ha.
Tharathei, Khamathei white, Chechat and purple maize were found better suited to cold conditions than the other varieties under the minimum temperature range of 1.1o C to 22.6o C and. The demonstrated front line was carried out in an 80 acre area. The average yield across the locations was 2.12 t/ha. In pre-kharif rice seed production studies in wetland rice, a spacing of 20 cm × 10 cm with 0.5 m spacing after every 1.5 m favored ease of intercropping and scrubbing, yielding a seed yield of 8.75 t/ha .
Growth experiments were conducted in soil ponds of 0.50 ha each in four different agro-climatic zones of Manipur from 1 April 2014 to 31 October 2014. In six to seven months, polyculture with semi-intensive farming practices yielded an average of 1500 - 1800 kg on an area of 0.5 ha.

These fruit fly catches coincided with the tomato fruiting period from April to June. Nine cultivars/hybrids of tomato were screened for fruit flies under open field conditions in Mizoram (Fig. 17). The number of alleles per locus ranged from 3 to 6 with an average of Fig. 20 Performance of green bean line MZFB-48.
Fruit fly attack in chilli, paprika and aubergine was the first report from India (Fig. 27). Methyl eugenol and cue lure based para-pheromone traps were used for monitoring and mass trapping of fruit flies (Fig. 29).

Application of increasing levels of common salt up to 20% at 20 DAS recorded significantly lower weed population and dry matter compared to application of common salt at 40 DAS (Table 2). The total organic carbon content decreased during that time and the lowest was recorded at 42ºC (Fig. 5). The occurrence of blast in rice, anthracnose in beans, leaf blight in colocasia and leaf spot in chili peppers were recorded.
The highest cob/plant (number) of maize was recorded in Chanki local (2.56) and the lowest was recorded by Nyakmakonglak (1.45). Screening experiments on maize showed that the maximum plant height was recorded by Ungma local-2 (209.7 cm) and lowest in Rubbermenti Yisemyong (102.3 cm). The maximum dry matter content was recorded by Ungma local-1 (129.72 g) and Vivek Sankul Makka recorded the minimum (9.47).

Effect of organic nitrogen sources on soil and water productivity rice (Oryza sativa L.) under different planting methods in the mid-hills of Sikkim.
To evaluate the effect of organic nitrogen sources on yield and water productivity of rice under different planting methods in Sikkim, an experiment was set up in a split-plot design that established two methods of rice production, namely System of Rice Intensification (SRI) and conventional. An experiment was conducted to study the effect of biocontrol agents, botanical and other organic approved fungicides against sheath blight in rice under artificially inoculated conditions. The effect of organic nutrient sources on the performance of garden pea (Pisum sativum L) and soil properties.
An experiment was conducted in ICAR Sikkim Center with 2 year old large cardamom cultivar Varlangey to study the effect of shade on the disease incidence and growth of the plants. Effect of cropping system on system productivity In order to evaluate the effect of diversified rice-based cropping system, a fixed plot field experiment was conducted in Completely Randomized Block Design (CRBD) consisting of seven cropping systems viz., rice-maize, rice-fenugreek (leafy greens). -corn (green heads), rice-broccoli-Sesbania (green manure), rice-vegetables-pea-corn (green heads), rice-coriander (green leaf)-cow pea (vegetables), rice-fenugreek (leafy greens) vegetables)- baby corn and rice-buckwheat (Fig 28).

The first observation was made at early vegetative stage and then at flowering stage followed by fruiting stage for various pathological aspects of various diseases like Ascochyta Blight, Botrytis fabae and Alternaria spot, rust, wilt and root rot. Various insect pests such as leaf miners and aphids were also observed. The results show that Table 3 Effect of fungicides in the control of banana leaf spot disease. Overall, the relative abundance of AMF in the soil around the root zone (pH 5) trended as Acaulospora laevis (71.1%) > Gigaspora calospora (13.2%) > Glomus mosseae (7.5%) > Glomus sp.
DMH 849 recorded three types of AMF while variety VQPM 9 recorded 2 types under FYM and vermicompost with spore density in the range of 190-440 per 100 gm soil. Organic fertilizers doubled the increase in AMF spore density over the control for all crops studied. To investigate the effect of resident nutrients on the growth of AMF, the data of samples of different jum sites were collected and regression analysis plots were constructed.
In general, nutrients such as SOC, available N and available P have a positive effect on spore reproduction of AMF. Fig. 26 represents the characteristic colonization of AMF in 40-day-old L. Leucocephala in the study together with control.
